Common Name(s): Ppg-9-steareth-3,ppg-9 peg-3 stearyl ether (combined ppg-9/peg-3 stearyl) derivative

DESCRIPTION

What It Does: Helps oil and water blend and provides emollient conditioning.

Why It's Used: Ppg-9 modification of peg-3 stearyl ether (combined ppg-9/peg-3 stearyl) gives hlb ~8–10; o/w balanced; ppg-9 lipophilicity + peg-3 hydrophilicity + stearyl emolliency.

How It Works: Ppg-9 arms provide lipophilic character; peg-3 stearyl ether (combined ppg-9/peg-3 stearyl) contributes the hydrophobic/emollient tail; hlb ~8–10.
