Ethoxydiglycol is a solubilizer, solvent, humectant, moisturizer, and perfuming agent widely used in cosmetics and personal care products. It boosts the efficacy of cosmetic formulations. Its chemical formula is C6H14O3.

What is ETHOXYDIGLYCOL used for?

Ethoxydiglycol is primarily used as a solvent in cosmetics to help dissolve or suspend other formulation ingredients. It is soluble in various other solvents like ethanol, propylene glycol, and vegetable oil, due to which it is found in almost every other cosmetic product like antiperspirants, soaps, nail polish removers, fragrances, hair conditioners, etc.
  • Skin care: It functions as a humectant and attracts moisture from the air and draws it into your skin, it improves moisture retention in the skin, and may help other topical ingredients to perform well. It prevents the skin from drying and also delays the signs of aging. It is used at a concentration of 1-10%. It boosts the efficacy of certain active ingredients like vitamin C, self-tanning active DHA, or benzoyl peroxide and is thus used in vitamin C serums
  • Hair care: It gives a longer-lasting and more uniform color to the hair, and also prevents split ends. Solvents like ethoxydiglycol are used to make thinner formulations and decrease the viscosity of a formulation to make the formulation readily spreadable on the skin or hair


The ethoxylation of ethanol produces Ethoxydiglycol. Ethoxylation is a chemical reaction in which ethylene oxide is added to a substrate. In this case, the substrate is ethanol, a type of alcohol.

What does ETHOXYDIGLYCOL do in a formulation?

  • Humectant
  • Solvent
  • Perfuming
