Ingredients Details
Cetyl Alcohol
Common Name(s): 1-hexadecanol,palmityl alcohol,n-cetyl alcohol
CAS Number: 36653-82-4
DESCRIPTION
What It Does: Provides c16 fatty alcohol emolliency and thickening for well-textured cosmetic emulsions.
Why It's Used: Lighter-textured fatty alcohol alternative to stearyl alcohol for creams and conditioners requiring less heavy emolliency.
How It Works: C16 chain length provides slightly lower melting point (49ยฐc) than stearyl (60ยฐc) giving softer, lighter emulsion texture. forms lamellar networks for thickening and stability. direct skin and hair conditioning via fatty alcohol film.
Typically Found In: Creams,hair conditioners,lotions
TECHNICAL DETAILS
Primary Category: Functional ingredient โ fatty alcohol
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%โ15%
SOURCING & ETHICS
Vegan Status: Yes โ 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 โ very low
Comedogenicity Rating: 1/5 โ 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
Cetyl alcohol's c16 chain length is at the approximate thermal transition point for fatty alcohol lamellar crystallization at skin temperature (33ยฐc). this transition (from ordered crystalline to disordered liquid phase near skin temperature) provides the characteristic 'melts on application' sensory profile that makes cetyl alcohol-containing products feel cooling and light on initial application.

Glycerin
Common Name(s): Glycerol,glycerine,1,2,3-propanetriol
CAS Number: 56-81-5
DESCRIPTION
What It Does: Glycerin pulls water from the environment and deeper skin layers into the outer skin layer (epidermis), boosting moisture levels and keeping skin soft, smooth, and plump.
Why It's Used: It is used in virtually every moisturizer, serum, and cleanser because it is highly effective at hydrating skin, is well-tolerated by all skin types, and enhances the texture and spreadability of formulations.
How It Works: As a humectant, glycerin forms hydrogen bonds with water molecules, trapping them in the skin. it also reinforces the skin barrier by integrating into lipid structures between skin cells.
Typically Found In: Moisturizers,serums,cleansers,toners,sheet masks,sunscreens,body lotions,shampoos,conditioners

SCIENTIFIC NOTE
Glycerin is an endogenous skin component found naturally in the stratum corneum. aquaporin-3 channels in keratinocytes facilitate glycerin transport, making it integral to natural skin hydration pathways.
