Description

Polyglyceryl-4 Oleyl Ether is a non-ionic surfactant derived from oleyl alcohol and polyglycerin, valued for its excellent emulsifying, dispersing, and solubilizing properties. This versatile compound is particularly effective in creating stable oil-in-water emulsions and offers enhanced mildness and skin compatibility. It is a key ingredient for formulators in the personal care, cosmetics, and pharmaceutical industries seeking high-performance, multifunctional raw materials.

Application

• Primary emulsifier and co-emulsifier in skin creams, lotions, and sun care products.
• Stabilizing agent for fragrances and essential oils in cosmetic formulations.
• Key ingredient in mild cleansing systems for facial washes, shower gels, and shampoos.
• Solubilizer for active pharmaceutical ingredients (APIs) and vitamins in topical preparations.
• Dispersing aid for pigments and powders in color cosmetics and make-up.
• Emollient and conditioning agent in hair care and skincare products.
• Component in industrial and institutional cleaning formulations requiring mild surfactants.
