About

An ethoxylated long-chain fatty alcohol surfactant with a C40-60 carbon chain range, used as an emulsifier.

C40-60 Pareth-3 is the polyethylene glycol ether of very long chain (C40-60) aliphatic alcohols. The very long carbon chain provides strong hydrophobic character and makes this ingredient particularly useful as an emulsifier for oil-in-water formulations. The ethoxylation degree of 3 mol EO provides limited water solubility. It is not specifically restricted in EU cosmetics regulation.
