Isodeceth-6

Isodeceth-6 is a polyethylene-glycol ether of branched isodecyl alcohol, used as a nonionic surfactant and emulsifier in cosmetics.

What it is

Isodeceth-6 is an ethoxylated alcohol made by reacting branched isodecyl alcohol with about six units of ethylene oxide. It functions as a nonionic surfactant and emulsifier, helping to blend oil and water phases and to solubilize oily or fragrance components into formulas. It is used as a processing aid in lotions, sun care, and other emulsions.

Safety & warnings

Isodeceth-6 is generally well tolerated as used in cosmetics. Like other PEG-type (ethoxylated) ingredients, manufacturing controls are used to limit residual reaction byproducts such as 1,4-dioxane.

Origin & sourcing

It is a synthetic ingredient produced by ethoxylating isodecyl alcohol, a branched fatty alcohol.
