SORBITAN TRISTEARATE

Description

Sorbitan tristearate is a versatile emulsifier and stabilizing agent commonly used in skincare and cosmetic formulations. This non-ionic surfactant is derived from sorbitol and stearic acid, making it a semi-synthetic ingredient with excellent compatibility with various cosmetic components. Sorbitan tristearate functions primarily as an emulsifier, helping to blend oil and water-based ingredients, creating stable and smooth textures in creams, lotions, and other skincare products.

With an HLB (Hydrophilic-Lipophilic Balance) value of 2.1, sorbitan tristearate is particularly effective in creating water-in-oil emulsions, which are beneficial for formulating rich, moisturizing products. It also acts as a thickening agent, enhancing the viscosity and texture of formulations. Sorbitan tristearate is known for its ability to improve the spreadability of products and provide a silky, non-greasy feel on the skin.

This ingredient is generally well-tolerated and considered safe for use in cosmetics. It is often used in concentrations ranging from 0.5% to 5%, depending on the formulation requirements. Sorbitan tristearate can enhance the stability and shelf life of products, making it a valuable component in various skincare formulations.
