Science
Mechanism of Action
This ingredient operates fundamentally as a non-ionic surfactant, an emulsifier, and a solubilizer. Its emulsifying action ensures the stable blending of immiscible substances, forming well-integrated oil-in-water emulsions crucial for product stability. As a solubilizer, it effectively disperses lipophilic compounds, such as essential oils and fragrances, into aqueous systems. Furthermore, it acts as a mild cleansing agent, gently lifting impurities from the skin without compromising its barrier function. Polyglyceryl-10 Caprylate/Caprate also contributes to skin conditioning and moisturization by forming a subtle protective layer that helps minimize moisture loss, leading to enhanced skin hydration and a smoother feel.

Key findings
- 01 Polyglyceryl-10 monocaprylate, a structurally similar compound, demonstrated superior removal efficacy against challenging pen eyeliner and good general makeup removal when self-assembled into transparent nanoparticles in water.
- 02 In a HET-CAM assay, polyglyceryl-10 monocaprylate exhibited a moderate irritation score of 8.4 at 4 wt%, which was observed to be lower than PEG-6 caprylic/capric glycerides, suggesting a comparatively milder profile.

The Formula
Formulation
Stability
Polyglyceryl-10 Caprylate/Caprate exhibits broad solubility, dissolving in water, ethanol, propylene glycol, various organic solvents, alcohol, isopropyl alcohol, vegetable oils, and silicones. While some references may suggest water insolubility, it is readily dispersible in hot water and acts as an effective hydrophilic oil-in-water emulsifier and solubilizer for aqueous systems. Its non-ionic nature generally ensures excellent compatibility across diverse cosmetic formulations.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that polyglyceryl fatty acid esters, including Polyglyceryl-10 Caprylate/Caprate, are safe for use in cosmetic formulations under current practices of use and concentration, provided they are formulated to be non-irritating. It is generally recognized for its low hazard profile by EWG, indicating a minimal risk of irritation at typical concentrations ranging from 1% to 10%. This ingredient is widely considered well-tolerated, non-irritating, and non-sensitizing. Notably, polyglyceryl esters offer the advantage of being free of 1,4-dioxane, a potential contaminant found in some PEG-based derivatives.
