Polydimethylsiloxyethyl Dimethicone
What is Polydimethylsiloxyethyl Dimethicone?
Polydimethylsiloxyethyl Dimethicone is a complex silicone polymer used in skincare formulations as a sensory modifier and film-former. It creates a smooth, non-greasy feel on the skin while helping to improve the spreadability and stability of emulsions. This ingredient is particularly valued in makeup primers and moisturizers for its ability to provide a silky texture and enhance product performance.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Slip modifier
Improves the spreadability and glide of products on skin.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Film former
Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.
