Sorbitan Sesquioleate

Description

Sorbitan Sesquioleate is a versatile emulsifier and surfactant widely used in cosmetic and skincare formulations. This amber-colored, oily liquid is derived from sorbitol and oleic acid, making it a semi-synthetic ingredient with both hydrophilic and lipophilic properties. Its primary function is to stabilize water-in-oil emulsions, allowing for the creation of smooth, homogeneous products.

In skincare applications, Sorbitan Sesquioleate acts as an effective dispersing agent, helping to evenly distribute active ingredients throughout a formulation. It also aids in improving the spreadability and texture of creams, lotions, and ointments. This ingredient is particularly valuable in formulations designed for dry or sensitive skin due to its mild, non-irritating nature.

Sorbitan Sesquioleate has a low HLB (Hydrophilic-Lipophilic Balance) value of approximately 3.7, making it suitable for creating stable water-in-oil emulsions. It is often used in combination with other emulsifiers to achieve optimal stability and texture in various cosmetic products. The typical usage concentration ranges from 0.5% to 5%, depending on the specific formulation requirements and desired product characteristics.
