Ingredients Details
Coumarin
Common Name(s): 2h-chromen-2-one,1,2-benzopyrone,tonka bean compound
CAS Number: 91-64-5
DESCRIPTION
What It Does: Provides the characteristic sweet hay-vanilla warmth central to fougère fragrance compositions.
Why It's Used: The fougère fragrance family-defining compound – coumarin is the essential warm-sweet note in lavender-oakmoss-coumarin fougère compositions that define men's cologne classics.
How It Works: Bicyclic lactone provides sweet hay-vanilla scent from its conjugated carbonyl system. good skin absorption for lasting fragrance. low volatility provides fixative properties.
Typically Found In: Fougère fragrances,men's cologne,warm oriental fragrances
TECHNICAL DETAILS
Primary Category: Fragrance component – lactone
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.001%–1%
SOURCING & ETHICS
Vegan Status: Yes – synthetic; natural from dipteryx odorata
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Eu cosmetics regulation: declared fragrance allergen. ifra guidelines restrict due to hepatotoxicity at high oral doses (not from topical use).
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Coumarin's natural source (tonka beans, dipteryx odorata) led to its historical use in food flavouring until toxicological studies revealed hepatotoxicity at high oral doses. the restriction of coumarin from food flavouring (eu and fda) drove fragrance reformulation in some cosmetic categories, though topical exposure levels from cosmetics are orders of magnitude below hepatotoxic doses.

Dimethicone
Common Name(s): Pdms,polydimethylsiloxane,silicone fluid
CAS Number: 9006-65-9
DESCRIPTION
What It Does: Provides silicone-characteristic silky feel and skin protection with adjustable viscosity.
Why It's Used: The benchmark cosmetic silicone – sets the gold standard for silky application feel, spreadability, and skin protection in virtually all skin care categories.
How It Works: Polydimethylsiloxane chain flexibility provides extremely low surface tension and high spreadability. inert si-o backbone provides chemical stability and excellent skin tolerance. occlusive film formation reduces tewl. higher viscosity grades provide more intense conditioning.
Typically Found In: Moisturizers,foundations,primers,sunscreens – nearly universal
TECHNICAL DETAILS
Primary Category: Functional ingredient – polydimethylsiloxane
Secondary Functions: Barrier sealing,softening
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%–30%
SOURCING & ETHICS
Vegan Status: Yes – synthetic
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
Dimethicone's exceptional silky feel arises from its very low intermolecular attractive forces (weak van der waals forces due to non-polar methyl groups) that allow silicone chains to slide freely over skin. the coefficient of kinetic friction for pdms against skin (~0.04) is among the lowest of any cosmetic material – explaining why even small amounts transform product feel.

Dimethiconol
Common Name(s): Dimethiconol,cosmetic active,functional ingredient
CAS Number: N/a
DESCRIPTION
What It Does: Delivers characteristic cosmetic function at recommended use concentration.
Why It's Used: Selected for functional contribution and formulation compatibility supported by cosmetic science and regulatory safety data.
How It Works: Works through the mechanism of its molecular class — physicochemical or biological interaction with skin proteins, lipids, or receptors as documented in peer-reviewed cosmetic literature.
Typically Found In: Skin care formulations
TECHNICAL DETAILS
Primary Category: Active ingredient – cosmetic active
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%–10%
SOURCING & ETHICS
Vegan Status: Conditional
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1–2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Dimethiconol has an established safety and efficacy profile within the cosmetic regulatory framework at standard use concentrations.

Isododecane
Common Name(s): Permethyl 99a,c12 isoparaffin,volatile hydrocarbon
CAS Number: 31807-55-3
DESCRIPTION
What It Does: Provides quick-dry volatile hydrocarbon carrier for colour cosmetics with complete evaporation and no residue.
Why It's Used: Primary colour cosmetic carrier — isododecane's volatility and excellent pigment dispersion combined with complete evaporation make it the standard carrier for long-wear foundations and colour cosmetics.
How It Works: Volatile isoparaffin (bp 177-188°c) evaporates from skin within 10-20 minutes. excellent pigment dispersion for colour cosmetics. spreading enhancement from low surface tension. no residue after evaporation provides clean, long-wear finish.
Typically Found In: Long-wear foundations,colour cosmetics,primers,sunscreens
TECHNICAL DETAILS
Primary Category: Functional ingredient – volatile hydrocarbon
Secondary Functions: Barrier sealing,softening
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 5%–60%
SOURCING & ETHICS
Vegan Status: Yes – synthetic
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
Isododecane's position as the preferred colour cosmetic carrier arises from a unique combination of properties that no other solvent provides simultaneously: volatility (complete evaporation for clean finish), pigment dispersion (superior to water or alcohols), compatibility with silicones (unlike many solvents), and skin safety (inert hydrocarbon without irritation potential of polar solvents).
