Sorbitan sesquioleate is a synthetic surfactant and emulsifier based on sorbitol and modified oleic acid. It is both a composite polymer emulsifier and a high performance W/O (water-in-oil) nonionic emulsifier, designed for ease of use and excellent performance.
This high-purity versatile ingredient is specially formulated for advanced cosmetic applications including creams, lotions, makeup, and sun care products. It delivers exceptional emulsion stability, texture enhancement, and formulation flexibility.
As a W/O emulsifier, it creates rich, stable formulations with superior spreadability and long-lasting performance. Its compatibility with various cosmetic systems makes it ideal for water-resistant makeup and protective skincare products.



It is commonly used in combination with other W/O emulsifiers to formulate sweat-resistant foundation gels, foundation creams, and water-in-oil emulsions.
Skincare: Ideal for heavy moisturizers, cold creams, or night balms.
Color Cosmetics: Improves pigment dispersion in foundations and lip balms.
Suncare: Improves dispersion of oil-soluble UV filters.
