About

A low-molecular-weight PEG diester that acts as a solubilizer and conditioning agent in cosmetic products. Widely used with a good safety profile.

PEG-6 Diisostearate is a polyethylene glycol (6 mol EO) diester of isostearic acid, functioning primarily as a solubilizer and skin-conditioning agent in cosmetic formulations. It is not listed in EU Annexes II–VI and carries no harmonized restrictions under Regulation (EC) No 1223/2009. Like all low-EO PEG esters, it may contain trace 1,4-dioxane as a manufacturing by-product.

Skin benefits

  • Solubilizes oil-soluble ingredients in aqueous formulations
  • Imparts smooth feel to skin and hair

Known concerns

  • Potential 1,4-dioxane trace contamination from manufacturing
