Why This Works for Your Specific Profile
Damage Index:
Damaged hair structure cannot withstand product intensity causing increased breakage and further compromise
Water Quality:
Fine hair becomes weighed down and greasy from heavy formulation
Hair:
Porous structure over-absorbs product leading to buildup, stiffness, or excessive dryness
Active Lifestyle:
High activity and frequent washing rapidly strip product benefits requiring excessive reapplication

Ingredients Details
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 โ 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 โ nearly universal
TECHNICAL DETAILS
Primary Category: Functional ingredient โ 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%โ30%
SOURCING & ETHICS
Vegan Status: Yes โ synthetic
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
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 โ explaining why even small amounts transform product feel.

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 โ 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 177-188ยฐc) 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 โ volatile hydrocarbon
Secondary Functions: Barrier sealing,softening
Application Areas:

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).
