SORBITAN LAURATE.

Valuable CAS 1338-39-2 / SURFACTANT - EMULSIFYING

Sorbitan Laurate is a versatile partial monoester, precisely engineered to function as a surfactant, emulsifier, and cleansing agent in advanced skincare formulations. It effectively reduces surface tension, enabling the stable blending of oil and water components while proficiently lifting impurities from the skin's surface.

Science

Mechanism of Action

This ingredient operates by decreasing the interfacial tension between disparate phases, facilitating the formation of stable and homogeneous emulsions from otherwise immiscible liquids. As a cleansing agent, its unique lipophilic (oil-loving) molecular structure allows it to bind to epidermal debris, excess sebum, and environmental particulates. This mechanism supports their efficient removal with water, contributing to clear skin and potentially mitigating conditions like acne by reducing microbial attachment.

While generally regarded as safe, concentrations of Sorbitan Laurate exceeding 5% significantly increase the likelihood of skin irritation. Formulations are typically designed to keep its concentration well below this critical threshold to ensure optimal functionality without adverse dermal reactions.

Stability

Sorbitan Laurate demonstrates good stability under standard conditions but is susceptible to hydrolysis when exposed to strong acid or strong alkali environments. It exhibits broad compatibility with a diverse range of cosmetic ingredients and synergistically enhances the performance of other emulsifiers.

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded Sorbitan Laurate is safe for use in cosmetics under current conditions of concentration and application, with a maximum recommended concentration of 5%. Although sorbitan esters as a class are classified as nonsensitizers, human provocative patch tests have reported a 0.4% incidence of positive reactions in individuals with contact allergy and dermatitis, suggesting a minor risk for highly sensitive skin types. Animal studies indicated mild, dose-dependent skin irritation. Furthermore, it holds approval as a food additive by the FDA and as an emulsifier in EU feedingstuffs.
