Common Name(s): Peg-6 dimethicone,peg-6 dimethicone,specialty silicone,sc conditioning polymer

CAS Number: N/a

DESCRIPTION

What It Does: Provides si-o backbone conditioning with low surface energy (20 mn/m) providing smooth, dry-touch skin feel.

Why It's Used: Si-o bond properties (low rotational barrier 0.6 kcal/mol, surface energy 20 mn/m, thermal stability >200°c) provide performance unavailable from organic emollients.

How It Works: Si-o backbone flexibility allows maximal surface contact. methyl group surface energy (20 mn/m) provides dry non-tacky feel. functional modifications extend performance scope.

Typically Found In: Skin care,hair care,conditioning
