Description

Oleth-8 is a non-ionic surfactant belonging to the polyoxyethylene alkyl ether family, derived from oleyl alcohol and ethylene oxide. This versatile compound is valued for its excellent emulsifying, solubilizing, and wetting properties, making it a critical component in formulations requiring stability and mildness. It is primarily used by manufacturers in the personal care, cosmetics, and pharmaceutical industries to create stable emulsions and enhance the delivery of active ingredients.

Application

• Primary emulsifier and solubilizer in cosmetic creams, lotions, and ointments.
• Key ingredient in hair care products such as conditioners and styling aids for its lubricating and antistatic effects.
• Wetting and dispersing agent in topical pharmaceutical formulations and medicated creams.
• Emulsifying agent for fragrances and essential oils in personal care products.
• Co-emulsifier and stabilizer in sunscreen and skincare formulations.
• Raw material in the synthesis of other specialty surfactants and chemical intermediates.
• Industrial applications as a lubricant additive and in textile processing aids.
