PEG-100 Stearate is a product of poly-ethoxylation of stearic acid (18-carbon backbone fatty acid) that contains 100 moles of ethylene oxide (polymer part). The raw materials have mixed origins, namely, petrochemical and botanical. PEG-100 Stearate is a white to light brown solid with a negligibly specific fatty scent.

It is used in skin care preparations as a nonionic surfactant, solubilizer, or emulsifier (HLB value of 18.8) with good hydrophilic properties, which allows the production of stable emulsions with lipophilic ingredients in water.

PEG-100 Stearate allows a combination of salts and other electrolytes in emulsions and is widely used in skin care preparations thanks to its stabilizing action. It is also often used with lower HLB value emulsifiers, such as Glyceryl Stearate, to form stable oil-in-water emulsions with a creamy consistency and good sensory profile.

PEG-100 Stearate is used in hand soaps, lotions, and creams. It can also be a solubilizer for perfumes, bath oils, or other aqueous alcoholic preparations. It is also a viscosity builder and humectant for night and replenishing creams.
