Ingredients Details
Caprylic/capric Triglyceride
Common Name(s): Mct oil,fractionated coconut oil,c8/c10 triglyceride
CAS Number: 73398-61-5
DESCRIPTION
What It Does: Lightweight, stable emollient that solubilizes oil-soluble actives for excellent delivery without greasy feel.
Why It's Used: Universal lightweight emollient base and solubilizer for oil-soluble actives in serums and low-viscosity formulations where mineral oil or petrolatum would be too heavy.
How It Works: Medium-chain length provides ideal balance of spreading coefficient, penetration rate, and barrier-sealing properties. excellent solubilizer for vitamin e, retinoids, and other lipophilic actives.
Typically Found In: Serums,facial oils,sunscreens,anti-aging products,hair products
TECHNICAL DETAILS
Primary Category: Active ingredient – medium-chain triglyceride emollient
Secondary Functions: Active solubilizer,spreading agent
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%–50%
SOURCING & ETHICS
Vegan Status: Yes – from coconut/palm kernel oil
Halal Status: Yes
Source Notes: Fractionated by hydrolysis and re-esterification of coconut oil. only c8 and c10 fatty acids retained.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 1/5 – very low; medium-chain length generally non-comedogenic
Sensitivity Concerns: Non-irritating.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Humectants,ceramides,actives as carrier
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Mct oil's medium-chain length (c8/c10) provides superior oxidative stability vs longer polyunsaturated chains and better skin aesthetics (lighter, less greasy) vs longer chain emollients (c16/c18). excellent solubilizer for retinoic acid, tocopheryl esters, and other lipophilic actives.

Cetearyl Alcohol
Common Name(s): Cetostearyl alcohol,c16-18 fatty alcohol
CAS Number: 8005-44-5
DESCRIPTION
What It Does: Provides fatty alcohol emulsification and thickening for stable, well-textured emulsions.
Why It's Used: The most widely used fatty alcohol in cosmetics – provides emulsification, thickening, and emolliency simultaneously from a single ingredient with excellent safety profile.
How It Works: Forms bilayer lamellar structures in water with emulsifiers creating a viscous structured network that thickens and stabilizes emulsions. fatty alcohol emolliency provides direct skin conditioning. bilayer formation reduces inter-droplet coalescence in emulsions.
Typically Found In: Creams,lotions,conditioners – virtually all emulsion products
TECHNICAL DETAILS
Primary Category: Functional ingredient – fatty alcohol emulsifier/thickener
Secondary Functions: Barrier sealing,softening
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%–25%
SOURCING & ETHICS
Vegan Status: Yes – from vegetable or coconut/palm fatty acids
Halal Status: Yes
Source Notes: Plant-derived, synthetic or animal-derived. verify source.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 1/5 – low; formulation-dependent
Sensitivity Concerns: Non-irritating.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Humectants,ceramides,actives as carrier
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Cetearyl alcohol's ability to form lamellar liquid crystal structures ('krafft phases') with water and co-emulsifiers provides not only emulsion stability but also enhanced skin penetration via the lamellar skin barrier pathway. these crystalline structures can act as a reservoir for active ingredients, slowly releasing them as the lamellar structure melts on skin contact.

Cocos Nucifera (coconut) Fruit Extract
Common Name(s): Cocos nucifera (coconut) fruit extract,botanical extract,phytochemical active

Why It's Used: Chosen for its natural origin narrative, traditional use heritage, and multi-functional phytochemical profile that supports several concurrent skin care claims from one ingredient.
How It Works: Polyphenols, terpenoids, and alkaloids in the extract scavenge ros via hydrogen atom transfer, inhibit nf-kb or cox-2 inflammatory pathways, and interact with skin surface proteins for conditioning.
