About

A long-chain ethoxylated fatty alcohol used as a co-emulsifier and viscosity enhancer in cosmetic formulations.

C30-50 Pareth-3 is the polyethylene glycol ether of C30-50 aliphatic alcohols with approximately 3 mol EO. The long alkyl chains provide strong hydrophobicity, making this ingredient useful as a co-emulsifier and thickener. The high carbon number means limited water solubility. It is not restricted under EU cosmetics legislation. These very long chain alcohols are typically derived from synthetic sources.
