Common Name(s): Ppg-4 laureth-7,ppg-4 laureth-7,cosmetic functional ingredient,established active

CAS Number: N/a

DESCRIPTION

What It Does: Provides the characteristic cosmetic function of its ingredient class through molecular chemistry at recommended use concentration.

Why It's Used: Ppg-4 laureth-7 is selected for its ppg-4 propylene glycol chain — the 4-repeat methyl-substituted ether backbone provides short-chain co-solvent and humectant with limited lipophilicity, distinguishing it from both unsubstituted peg (fully hydrophilic) and organic glycols (no lipophilic tail).

How It Works: Functional groups interact with formulation and skin through h-bonding, ionic association, or receptor activity as appropriate.

Typically Found In: Cosmetic formulations
