Dive deep into the science of coconut oil in skincare—one of the most debated, misunderstood, and widely used ingredients in both natural beauty formulations and artisanal skincare products. In this episode, we break down the truth behind coconut oil for skin, separating hype from cosmetic chemistry facts so you can confidently decide whether it belongs in your routine or on your formulation bench.
We explore the critical differences between unrefined virgin coconut oil and fractionated coconut oil (MCT oil), analyzing their molecular structure, fatty acid composition, and real-world performance in skincare formulations. With a high concentration of lauric acid, coconut oil offers powerful antimicrobial properties and forms a strong occlusive barrier that helps lock in moisture—making it a staple in body butters, sugar scrubs, and cold-processed soap recipes.
But is coconut oil comedogenic? We take a close look at the comedogenic rating of coconut oil, how it interacts with different skin types, and why it may trigger breakouts and clogged pores—especially in acne-prone or oily skin. Learn when to embrace coconut oil for deep hydration and skin softening, and when to avoid it in favor of lightweight, non-comedogenic oils for facial skincare formulations.
Perfect for cosmetic formulators, DIY skincare creators, and clean beauty enthusiasts, this episode covers everything from ingredient selection and formulation balance to holistic skincare education. Whether you're crafting luxury handmade soaps or developing non-toxic skincare products, this is your guide to understanding the true chemistry behind coconut oil.

We are embarking on an extraordinary journey. This isn’t just a brief look at an ingredient; this is a deep dive.
Today, we are opening the ultimate Alluring Tranquility archive to conduct a massive ingredient deep dive into one of the most famous, highly debated, and multifaceted raw materials in the botanical world: Yes, we are talking about Coconut Oil. It has been elevated to mythical status as a cure-all that can solve every beauty dilemma from head to toe, yet simultaneously blacklisted by dermatologists as a pore-clogging hazard.
Today, we are going to strip away the loud marketing noise, the social media trends, and the skincare myths. We are diving deep into the exact molecular chemistry, structural mechanics, and formulation realities of this tropical powerhouse. We are going to explore how this single oil behaves across the entire spectrum of artisan product creation. We'll cover why it can transform a bar of cold process soap into a foaming luxury, but it can spell absolute disaster for a facial moisturizer. We will look at its performance in hard-working heel balms, whipped body butters, emulsified lotions, exfoliating sugar scrubs, delicate lip care, and Structural Hair Care Treatments
Let's begin our deep dive into the true nature of coconut oil
The Chemical Anatomy of Cocos Nucifera or Coconut Oil
To understand how an ingredient behaves on the skin or hair, you must first understand its molecular structure. You cannot formulate with intention until you know exactly what is happening at a chemical level. Coconut oil is cold-pressed or expeller-pressed from the internal white kernel or meat of mature coconuts harvested from the Cocos nucifera palm tree. When you hold raw, virgin coconut oil in your hands at normal
room temperature, it feels completely different from liquid plant oils like sunflower, argan, or grapeseed. It is a solid, pearlescent white fat that behaves almost like a soft butter. This solid-to-liquid transformation happens at a very specific temperature: 76 degrees Fahrenheit. The moment your environment or your skin drops below that number, the oil locks into a rigid, crystalline structure. The second it climbs above it, the crystals
melt instantly into a crystal-clear, low-viscosity liquid. This sharp phase change is a vital tool for formulators. Why does it behave this way? The secret lies within its fatty acid profile. Unlike many liquid vegetable oils that are rich in unsaturated fluid fats, coconut oil is composed of roughly 90% saturated fatty acids. In organic chemistry, saturated fatty acids have single bonds between their carbon atoms. This allows their molecular chains to be straight and linear. Because they are straight, they can pack tightly together like bricks in a wall, which is why the oil stays solid at
cooler temperatures.
Let’s break down the fatty acid profile of coconut oil,
because this dictates everything it does: [Coconut Oil Fatty Acid Distribution]
Lauric Acid (C12): ███████████████████████████ 49%
Myristic Acid (C14): ██████████ 18%
Caprylic/Capric: ███████ 13%
Palmitic Acid (C16): ████ 8%
Oleic Acid (C18:1): ███ 6%
Linoleic Acid (C18:2):█ 2%
First, we have the undisputed king of coconut oil: Lauric Acid, representing approximately 49% of the total oil profile. Lauric acid is a medium-chain fatty acid and a biological powerhouse. It has an incredibly high affinity for proteins and features unique antimicrobial, antibacterial, and antifungal properties.
Next comes Myristic Acid at about 18%. This specific acid provides exceptional cleansing properties when turned into soap, while offering great slip and structural body in leave-on applications.
Then we have Palmitic Acid sitting at around 8%. This is a heavier saturated fat that mirrors the skin's natural lipid barrier, providing excellent structure and protection against dryness.
The remaining profile consists of short-chain Caprylic and Capric acids, a small dash of monounsaturated Oleic Acid, and a tiny 2% fraction of polyunsaturated Linoleic Acid. Because it contains so little linoleic acid, Coconut oil is highly resistant to oxidation. It can sit on your formulation shelf for up to two full years without going rancid, making it an incredibly reliable base ingredient.
The Skincare Paradox – Facial Realities vs. Topical Triumphs
The Facial Verdict – Will It Clog Pores?
Now that we understand the chemistry, let's address the big question that every clean beauty brand and conscious consumer runs into: Can I use coconut oil in my daily face cream? Or will it cause a major
breakout?
Let's look closely at the science. In cosmetic chemistry, we evaluate every single oil and butter on a standardized comedogenic scale ranging from 0 to 5.
0: Completely non-comedogenic; will not clog pores.
1: Very low probability of clogging pores.
2: Moderately low; safe for most skin types.
3: Moderate; can cause congestion in acne-prone individuals.
4: Highly comedogenic; high probability of clogging pores.
5: Severely comedogenic; almost guaranteed to cause acne.
Coconut oil sits at a resounding 4 out of 5 on this scale. Because of those tightly packed, straight-chain saturated fatty acids—specifically the combination of lauric, myristic, and palmitic acids—coconut oil creates a highly cohesive, heavy film when applied to the skin. On the body, this is fantastic. But on your face, your skin has an incredibly high density of sebaceous glands, which are microscopic exocrine glands in the skin that
secrete Sebum, which is an oily and waxy substance. When you apply a leave-on face cream containing a high percentage of coconut oil, the heavy, occlusive layer sits directly over your pores. It traps sebum, sweat, pollution, and dead keratinized skin cells underneath it. This lack of breathability creates an ideal suffocating environment, promoting acne-causing bacteria. If you are prone to breakouts, oiliness, or combination skin, coconut oil can lead to blackheads, whiteheads, and deep cystic blemishes. If your goal as a creator or user is to build a facial moisturizer that imparts a fresh, youthful radiance, you want to avoid coconut oil entirely. Instead, look to non-comedogenic alternatives. Consider Jojoba Oil, which is technically a liquid wax ester that closely mimics the human skin's natural sebum, helping to balance oil production. Or choose Squalane, a lightweight, completely stable lipid that provides deep moisture without suffocating the pores, or Rosehip Seed Oil, which is rich in polyunsaturated linoleic acid to bring dynamic brightness and nourishment to the skin. Leave the coconut oil out of facial products and save it for areas that truly require its protective strength.
The True Calling – Trans-Epidermal Water Loss and Body Care
Now that we have set clear boundaries for facial care, let's look at the areas where coconut oil excels. The skin on your body—especially on your arms, legs, elbows, and torso—is anatomically very different from the skin on your face. It is thicker, has far fewer sebaceous glands, and is constantly exposed to the elements, friction from clothing, and drying environmental factors. This is where coconut oil becomes a true asset. One of its greatest strengths is its ability to combat Trans-Epidermal Water Loss (TEWL). When your skin barrier becomes compromised due to dry weather, harsh body washes, or aging, the microscopic lipids that hold your skin cells together begin to deplete. This allows deep hydration to evaporate into the air, leaving your skin looking dry, flaky, and dull. Because of its heavy saturated fat content, coconut oil acts as a highly effective emollient and occlusive barrier. It fills the gaps between your skin cells, smoothing flakiness and locking essential moisture deep within the skin.
Additionally, we cannot ignore the therapeutic benefits of its high lauric acid content. When you apply coconut oil to irritated or compromised skin on the body, it doesn't just moisturize; it provides a clean, protected environment for the skin to heal naturally. It acts as a shield against environmental stressors, making it a reliable choice for rich body lotions, deep moisturizing creams, and protective salves. So right now let's enter the artisan's studio for a minute and let's talk about – Formulating Across Product Lines.
Cold process soap: coconut oil adds hardness and a rich lather; to achieve that, you want between 15 and 25% of the total oils and butters to be Coconut Oil.
Heel balms and salves: coconut oil adds heavy occlusion and a shield. To achieve this, you want to have between 30 and 50% of your total oils and butters to be coconut oil.
Lotions and Body Butters: coconut oil gives your product that great melt-on-contact sensation. To achieve this, you want between 10 and 30% of your total oils and butters to be coconut oil.
Sugar & Salt Scrubs: coconut oil adds a great suspension base for the scrub, to achieve this, you want to have between 40 and 60% of your total oils and butters to be coconut oil.
Saponification Kinetics – The Architecture of Soap
Let's step directly into the soap-making laboratory, because this is where coconut oil undergoes a complete molecular transformation. In cold process soap making, we aren't simply blending raw ingredients together. We are managing a definitive chemical reaction called saponification. When you combine plant oils with an alkali—specifically sodium hydroxide (lye) dissolved in water—the lye cleaves the glycerol backbone off the fatty acids, converting them into sodium salts. This reaction creates an entirely new substance: natural soap. Every single oil you select for your soap recipe contributes a distinct property to the final bar. For example, olive oil provides exceptional conditioning but produces a low, slimy lather. Castor oil provides excellent bubble stability. But coconut oil? Coconut oil provides structural strength and performance. When coconut oil undergoes saponification, its high concentration of lauric and myristic acids converts into sodium laurate and sodium myristate. These two molecular salts are responsible for two critical characteristics in a bar of soap: unmatched hardness and an incredibly fluffy, voluminous lather. If you try to formulate a natural bar of soap without any hard fats or coconut oil, you will often end up with a soft, spongy bar that dissolves quickly in water and produces a weak, minimal lather. Coconut oil ensures your bar cures to a rock-hard texture that lasts in the shower while generating big, luxurious bubbles that rinse away cleanly. However, there is an important caveat that every artisan maker must respect: Coconut oil cleanses with extreme efficiency. Sodium laurate has an exceptionally strong affinity for oils. If the percentage of coconut oil in your soap recipe is too high, it will not only strip away surface dirt but also wash away the skin's natural protective lipid barrier. This can leave the skin feeling tight, itchy, dry, and irritated after a shower. To create a balanced, skin-loving bar of soap, a good rule of thumb is to cap your coconut oil at 15%-25% of your total oil blend. To ensure the bar remains gentle, you should always design your recipe with an intentional superfat—typically between 5% and 8%. A superfat means you add extra oils that do not convert into soap, leaving them to float freely within the rich lather to
condition and protect the skin while it cleanses. When formulated with this balance, your soap will deliver an outstanding cleansing experience without stripping the skin.
Anhydrous Formulations – Heel Balms, Lotions, and Body Butters
Moving away from the wash-off products, let's discuss leave-on artisan body care, starting with one of my absolute favorite targeted treatments: Heel Balms. The anatomy of our feet is entirely unique. The skin on your heels is remarkably thick to withstand constant impact, and it contains absolutely zero sebaceous glands. Because they cannot produce their own oils, your feet rely entirely on external moisture to maintain their elasticity. When feet are neglected, the thick skin dries out, loses its flexibility, and splits into deep, painful cracks. This is where coconut oil truly shines. When you formulate a dedicated heel balm, you can use a much higher percentage of coconut oil—often between 30% and 50% of the formula. When you blend it with structural elements like natural beeswax and rich seed butters, coconut oil creates a heavy, durable shield that stays put. It fills in those deep micro-cracks, softens tough calluses, and its natural properties help keep the skin clean and protected. It is an exceptional ingredient for high-performance foot care. Now, we’ll shift our focus to Whipped Body Butters and Emulsified Lotions. In an anhydrous whipped body butter—such as a blend of shea, mango, and cocoa butters—coconut oil provides the "melt-on-contact" effect. Because its melting point is 76 degrees Fahrenheit, a whipped butter containing coconut oil looks like a fluffy, dense cream in the jar. But the moment a scoop touches your warm skin, your body heat lowers the melting point, causing the butter to melt instantly into a smooth liquid that glides effortlessly across your skin. However, keep this formulation tip in mind: if your body butter contains too much coconut oil, it can leave a greasy, heavy residue that takes a long time to absorb. To solve this like a professional formulator, balance your recipe by incorporating a small percentage of a natural starch—like Arrowroot Powder or cornstarch—at around 1% to 2% of your total weight, or blend it with a lightweight,
dry ester like Isopropyl Myristate. This cuts through the heavy feel of the saturated fats, giving your whipped butter a velvety, high-end matte finish. In Emulsified Lotions—where water and oil are brought together with an emulsifying wax—coconut oil adds excellent body, stability, and thickness to the cream. It gives the lotion a rich feel upon application, though it should be combined with fluid oils like sweet almond or apricot kernel oil to ensure a balanced, comfortable skin feel.
Exfoliation Physics –Lets talk about Crafting the Perfect Sugar Scrub
Let’s move on to an indispensable product in any artisan bath line: The Sugar Scrub. Have you ever purchased a natural sugar scrub, only to open the jar and find all the oil floating in a thick pool at the top, while the sugar has settled into a rock-hard, immovable brick at the bottom? This separation occurs when a scrub is formulated exclusively with liquid oils such as sunflower, olive, or canola oil. These oils lack the structural density to hold the heavy exfoliating granules in place. This is where coconut oil acts as a fantastic natural stabilizer. Because it semi-solidifies at standard room temperatures, it forms a soft, cohesive matrix that holds organic sugar granules in a perfectly uniform suspension. It creates a stable, scoopable texture that won't separate on retail shelves or in your bathroom. When you scoop that scrub out of the jar and apply it to
damp skin in a warm shower, the thermodynamics change completely. The combination of warm water and your natural body heat instantly breaks down the coconut oil's crystalline structure. It melts down completely, allowing the sugar granules to glide smoothly over your skin without scratching or causing irritation. As the sugar gently removes dead, dull skin cells from the surface, the melting coconut oil steps in
immediately to condition the newly exposed skin. When you rinse the scrub away, the sugar dissolves completely, while the coconut oil leaves behind a light, velvety, moisture-locking barrier. You step out of the shower with skin that feels completely exfoliated, soft, and beautifully conditioned, eliminating the need for an extra step of lotion.
Specialized Anatomy – Advanced Application in Lip & Hair Care
Lip Care – The Lip Barrier Dilemma. Now, we're going to explore an area of specialized skincare that requires careful attention: Lip Care. Just like our heels, our lips have a completely unique anatomical structure. The skin on our lips is incredibly thin—consisting of only three to five cellular layers compared to the fifteen to sixteen layers on the rest of the face. The lips contain no sweat glands or sebaceous glands, meaning they have no natural means of forming a protective hydrolipid film. They are highly susceptible to drying out and chapping from wind, sun, and cold weather.
When you add coconut oil to a lip balm or a gentle lip scrub, its rapid melting behavior provides immediate relief for dry skin. It offers an elegant glide that prevents the balm from dragging across sore, sensitive lips, leaving behind a subtle, flattering radiance. Its lauric acid content also helps protect chapped or split lips as they recover. But as a formulator, you must account for its low melting point. If you create a lip balm using primarily
Coconut oil will soften too much in a pocket or car during warmer months, and it will evaporate off the lips too quickly to offer long-term hydration. To create a successful artisan lip balm, coconut oil must be paired with firm structural components. You want to combine it with hard botanical waxes—such as Beeswax or Candelilla Wax—which provide structural integrity and a higher melting point. Pair these with slow-absorbing, protective butters like Shea Butter or Cocoa Butter. The wax creates a durable barrier on the lips that holds the coconut oil in place, allowing it to provide deep, continuous hydration over several hours.
The Chemistry of Hair Penetration
For our final technical segment today, we are stepping into the field of haircare. This is where coconut oil reveals an extraordinary property that separates it from almost every other vegetable oil on earth. In hair science, oils are fundamentally divided into two distinct groups based on how they interact with the hair shaft: coating oils and penetrating oils. Coating oils—like jojoba, argan, and broccoli seed oil—have large, bulky, complex molecular structures. They cannot fit beneath the protective outer cuticle scales of the hair strand. Instead, they sit smoothly on the surface, sealing the cuticle, reducing frizz, and acting as a shield to enhance external shine. They are excellent for surface styling. Coconut oil, however, is a premier penetrating oil. It doesn't simply coat the surface; it travels deep into the hair shaft, past the outer cuticle, and embeds itself directly inside the inner core, known as the cortex. So, how does it achieve this? It all comes down to its chemical structure. As we established, coconut oil is predominantly made up of lauric acid. Lauric acid has a completely straight, compact molecular chain and a very low molecular weight. Crucially, it possesses a strong chemical affinity for hair proteins. Your hair is composed of a tough, fibrous protein called keratin. Because lauric acid is small and structurally linear, it easily slips between the overlapping scales of the hair cuticle, binding directly to the internal protein chains inside the cortex. This molecular ability makes coconut oil a powerful defense against hygral fatigue. Every time you wash your hair, the hair shaft absorbs
water and swells up like a sponge. As it dries, it shrinks back down to its normal size. This continuous swelling and contracting places incredible structural stress on the hair fiber over time, eventually causing the cuticle scales to lift, crack, and break. This leads to split ends, brittleness, and chronic frizz. By applying a coconut oil treatment to your hair before you wash it—a technique affectionately known in our home as a "pre-poo" treatment—the oil occupies the spaces within the cortex. Because oil and water repel each other, the embedded coconut oil prevents the hair
shaft from absorbing excess water. This controls the swelling process during washing, protects the hair's internal protein structure, and maintains its natural strength. However, we must look at the flip side: Coconut oil is not suitable for every hair type. Because it fills the hair shaft so effectively and binds to proteins, it can cause a buildup on certain hair textures. If you have very fine hair, low-porosity hair, or hair that is naturally protein-dense, coconut oil can overload the strands. Instead of leaving the hair soft and manageable, it can make it feel stiff, brittle, rough, and weighed down. Coconut oil is truly at home when used on thick, coarse, curly, or highly porous hair types that need internal structural support and deep moisture sealing. For these textures, it adds exceptional elasticity, bounce, and a beautiful shine. When formulating artisan haircare products like solid conditioner bars or rich hair masks, balance is everything. If you are designing a general hair serum, avoid using pure coconut oil. Instead, blend its deep-penetrating properties with lightweight, surface-coating oils like camellia seed or argan oil. This combination ensures your product delivers both internal structural support and a weightless, smooth finish on the outside.
Elevating the Craft
It is truly remarkable to realize how much depth, science, and artistry can be found in a single ingredient from nature. When we take the time
to step away from the surface trends and look closely at the molecular reality of an oil like coconut, we unlock the true potential of intentional creation. So, today, we talked about how there are no inherently "perfect" or "imperfect" ingredients in skincare. There are only ingredients used in the right context, at the right percentages, for the right parts of our perfectly unique bodies. Understanding these details is what transforms a simple hobby into a true craft and a standard routine into a meaningful ritual of self-care. Whether you are formulating a beautifully balanced bar
of soap for your shop, whipping up a rich butter for the winter months, or simply choosing the right products to care for your own hair and skin—remember to create with intention, honor the science behind the botanicals, and listen to what your body is telling you.
