Common Name(s): Polyglyceryl-3 decyltetradecyl ether,pg-3 decyltetradecanol ether,branched c24 polyglycerol ether

DESCRIPTION

What It Does: Helps oil and water blend in formulas while providing a smooth skin feel that remains stable in cold temperatures.

Why It's Used: Branched c24 chain on pg-3 provides cold stability; ether linkage provides hydrolytic stability; hlb ~7-9 for o/w emulsification.

How It Works: Ether linkage; branched decyltetradecyl c24 chain reduces crystallization versus linear c24 fatty ethers; pg-3 hydrophilic head; hlb ~7-9.

Typically Found In: Cold-stable creams,o/w emulsions,natural cosmetics
