The ingredient narratives reshaping clean beauty.

Dimethicone

aka polydimethylsiloxane · PDMS · dimethylpolysiloxane

Silicone polymer providing slip, adhesion, and wear in colour cosmetics. Under pressure from the silicone-alternatives trend in clean beauty despite an excellent human safety record.

Benefits
  • Slip and glide in eyeshadow and lip formulas
  • Wear and adhesion improvement
  • Semi-occlusive barrier protection
  • Smooth application texture
  • Long-wear performance
Example uses
  • Eyeshadow sticks
  • Silky primer formulas
  • Long-wear lip products
  • Foundation vehicles
  • Skin prep serums
Formulation notes

Functions in anhydrous or low-water colour cosmetics. Immiscible with water unless specifically emulsified. Forms flexible silicone film on skin surface.

Watchouts

Non-biodegradable — environmental persistence concern in rinse-off products. Banned in many clean-beauty brand standards on environmental grounds despite strong human safety profile.

Clean beauty perception

Contested in clean beauty. Excellent human safety profile but environmental persistence drives exclusion. Clean-beauty movement has positioned silicones as problematic despite limited evidence of skin harm at cosmetic use.
