Science
Mechanism of Action
As a non-ionic surfactant, Sorbitan Palmitate primarily functions by reducing the surface tension between immiscible oil and water phases, enabling them to blend uniformly and maintain a stable emulsion over time. This mechanism prevents phase separation, ensuring product consistency. It also acts as an auxiliary emulsifier and dispersant, improving the even distribution of other ingredients within a formulation, contributing to a smooth skin feel, and potentially offering mild moisturizing benefits.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Sorbitan Palmitate is safe for use in cosmetics under current concentrations and conditions, with safety assessments conducted up to 100% concentration. While sorbitan esters as a class may exhibit mild skin irritation, comprehensive human studies, including a 206-subject Repeated Insult Patch Test (RIPT), found Sorbitan Palmitate to be non-irritating and non-sensitizing.
