Science
Mechanism of Action
This ingredient functions as an effective emulsifier, facilitating the stable blending of disparate oil and water phases within a formulation. As a mild surfactant, it enables gentle yet thorough cleansing, making it particularly suitable for sensitive skin. Furthermore, it acts as a PEG-free refatting agent, helping to replenish the skin's lipid content, thereby improving skin feel and reducing transepidermal water loss (TEWL) to enhance the skin barrier. It also offers mild antimicrobial and deodorizing properties, and can support the penetration of other active ingredients.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Polyglyceryl-3 Caprate, within a group of 274 polyglyceryl fatty acid esters, is safe for cosmetic use under current practices and concentrations, provided the final formulations are non-irritating. It demonstrates a low risk of inducing irritation or allergic reactions and is generally well-tolerated, including by individuals with sensitive skin.
