Ingredients Details
Almond/borage/linseed/olive Acids/glycerides
Common Name(s): Almond/borage/linseed/olive acids/glycerides
DESCRIPTION
What It Does: Loosens corneocyte adhesion in the stratum corneum, accelerating cell turnover, refining skin texture, and improving radiance.
Why It's Used: Organic acids at cosmetic ph values provide controlled keratolytic exfoliation that improves skin texture, pore appearance, and radiance without mechanical irritation.
How It Works: At appropriate ph, the acid's undissociated form penetrates the stratum corneum and dissolves the ionic bonds between corneocyte desmosomes (calcium chelation mechanism), facilitating controlled desquamation and cell renewal.
Typically Found In: Toners,exfoliants,serums,peels,cleansers
TECHNICAL DETAILS
Primary Category: Exfoliants
Secondary Functions: Brightening,keratolytic
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.5–20%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Synthetic or plant-derived acid; no animal components.
SKIN COMPATIBILITY
Irritancy Rating: 2
Comedogenicity Rating: 0
Sensitivity Concerns: May cause irritation or stinging in sensitive or barrier-compromised skin at high concentrations; patch test recommended.
Safe for Sensitive Skin: Conditional
SAFETY & COMPATIBILITY
Safety Profile: Safe within recommended ph and concentration ranges. sensitization risk increases above 10% aha. patch test recommended for sensitive skin. mildly irritating to some individuals at typical cosmetic use concentrations.
Works Well With: Niacinamide,hyaluronic acid,ceramides,vitamin c
Avoid Combining With: High concentrations on sensitive/broken skin; avoid with physical exfoliants
SCIENTIFIC NOTE
Cosmetic acids function at the pka boundary: only the undissociated acid (rcooh) penetrates the stratum corneum lipid barrier, while the ionized carboxylate (rcoo⁻) does not. the henderson-hasselbalch equation governs the fraction of active species at formulation ph; typically 0.5–3.0% undissociated acid provides efficacy while minimizing irritation.

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 (49°c) than stearyl (60°c) 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 – 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%–15%
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
Cetyl alcohol's c16 chain length is at the approximate thermal transition point for fatty alcohol lamellar crystallization at skin temperature (33°c). 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.

Coco Caprylate/caprate
Common Name(s): Coco caprylate/caprate
DESCRIPTION
What It Does: Smooths and softens skin by filling intercorneocyte spaces, reducing friction, and providing a pleasant aesthetic skin feel in formulations.
Why It's Used: Synthetic esters provide tailored aesthetic properties — spreadability, skin feel, volatility, refractive index — that natural oils alone cannot consistently deliver.
How It Works: The ester molecule fills microscopic surface irregularities between corneocytes, reducing coefficient of friction, reflecting light uniformly, and providing a lubrication layer that protects the skin surface.
Typically Found In: Moisturizers,sunscreens,color cosmetics,body lotions,lip products
TECHNICAL DETAILS
Primary Category: Synthetic emollients
Secondary Functions: Emollient
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1–20%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Synthetically produced ester emollient; no animal components.
SKIN COMPATIBILITY
Irritancy Rating: 1
Comedogenicity Rating: 1
Sensitivity Concerns: Low sensitization potential at recommended use concentrations.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Well-characterized cosmetic ingredient with established safety profile. generally non-irritating at typical use concentrations. suitable for leave-on and rinse-off cosmetics.
Works Well With: Silicones,uv filters,other emollients
Avoid Combining With: Strongly alkaline conditions (risk of saponification of ester-type emollients)
SCIENTIFIC NOTE
The spreading coefficient of an emollient is governed by its surface tension, viscosity, and polarity. esters with branched alkyl chains (e.g., isopropyl, isostearyl) spread rapidly and leave a non-tacky film; linear long-chain esters provide more substantive moisturization. hlb value determines the preferred formulation system (w/o vs o/w emulsions).

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
TECHNICAL DETAILS
Primary Category: Humectant
Secondary Functions: Skin barrier support,emollient,solvent
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%–30% (typical: 3–10%)
SOURCING & ETHICS
Vegan Status: Yes – plant-derived (coconut, soy, palm) or synthetic
Halal Status: Yes – when plant-derived or synthetic; verify source with supplier
Source Notes: Derived from plant oils via hydrolysis or saponification; synthetic versions also available. palm-derived glycerin carries sustainability concerns.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low; non-irritating at all standard concentrations
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Extremely rare allergic reactions; generally safe for all skin types including sensitive and baby skin
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Widely recognized as safe. ewg hazard score: 1. no significant concerns for irritation, sensitization, or toxicity at typical concentrations (up to 50%).
Works Well With: Hyaluronic acid,ceramides,niacinamide,panthenol,urea,peptides,retinol,ahas/bhas
Avoid Combining With: No known incompatibilities at standard concentrations
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.
