Common Name(s): Peg/ppg-3/10 dimethicone,peg/ppg-3/10 dimethicone,silicone peg/ppg emulsifier
DESCRIPTION
What It Does: Helps silicone and water blend together smoothly for a light, non-greasy skin feel.
Why It's Used: Peg-3/ppg-10 balance (hlb ~5) enables stable w/si emulsification with excellent skin feel.
How It Works: Peg-3 arms are hydrophilic; ppg-10 arms provide intermediate polarity; dimethicone backbone anchors in silicone phase; hlb ~5 enables w/si emulsification.
Typically Found In: Water-in-silicone emulsions,lightweight sunscreens,silicone skin care,primers
