Methyl gluceth-20

Methyl Gluceth-20, CAS 68239-42-9, is a polyethoxylated methyl glucose derivative carrying approximately 20 ethylene oxide units. It is also referenced under the names Gluco e 20, MethylGluceth, methyl glucose-20, and POE 20 methyl glucose. No E-code applies to this ingredient.

In rinse-off and leave-on personal care formulations, Methyl Gluceth-20 functions as a humectant by binding water within the skin matrix and as a co-emulsifier that stabilises oil-in-water systems through its amphiphilic ethoxylated structure. In pharmaceutical topical preparations, it serves as a carrier solvent that improves active ingredient solubility and spreadability.

Methyl Gluceth-20 is supplied in cosmetic and pharmaceutical grades and falls under REACH registration requirements for EU market access. Procurement quantities are typically available in drum and IBC formats. Buyers should confirm grade specifications against relevant regional cosmetic regulations, including EU Cosmetics Regulation 1223/2009.
