Common Name(s): Peg-8 dimethicone/dimer dilinoleic acid copolymer
DESCRIPTION
What It Does: Creates premium elastomeric silky texture with better compatibility with organic ingredients than standard silicone.
Why It's Used: Used where silicone elastomeric texture is desired alongside improved organic oil compatibility.
How It Works: Peg-8 dimethicone enables w/si emulsification; dimer acid copolymerization adds organic affinity and elastomeric network.
Typically Found In: Premium hybrid skin care,w/si emulsions
