Emulsifying Emollient Hydrating Surfactant

Science

Mechanism of Action

This ingredient functions primarily as an effective emulsifier, enabling the stable combination of immiscible oil and water components crucial for uniform product consistency and texture. It also acts as a mild surfactant, reducing surface tension between ingredients to enhance cleansing efficacy, and as an emollient and hydrator, helping to maintain skin softness and smoothness.

Dusting Analysis

Not commonly dusted

As a fundamental emulsifier and emollient, Polyglyceryl-10 Dioleate's functional concentration range is well-defined (1-5%). Its inclusion typically indicates a genuine functional role in product stability, texture, and conditioning, rather than being used at sub-efficacious levels merely for label appeal.

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that polyglyceryl fatty acid esters, including Polyglyceryl-10 Dioleate, are safe for use in cosmetics under current practices of use and concentration, provided formulations are non-irritating. This aligns with general safety assessments by regulatory bodies such as the FDA and compliance with European cosmetic regulations. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) of 0-25 mg/kg body weight for polyglycerol esters of fatty acids.
