POLYGLYCERYL-10 MONO/DIOLEATE.

Valuable CAS - / SKIN CONDITIONING

Polyglyceryl-10 Mono/Dioleate is a highly effective nonionic emulsifier designed to seamlessly integrate oil and water phases in cosmetic formulations, thereby boosting product stability and refining texture. This polyglycerin derivative further enhances skin's moisture balance and provides a luxurious, smooth feel.

Emulsifying Skin conditioning Surfactant Dispersing Stabilizing Hydrating

Science

Mechanism of Action

This ingredient primarily functions as a nonionic, hydrophilic emulsifier, critically reducing the interfacial tension between oil and water phases to create stable emulsions. It also acts as an effective dispersing and stabilizing agent within formulations. Beyond its emulsifying capabilities, Polyglyceryl-10 Mono/Dioleate contributes to maintaining skin hydration and imparts a refined tactile experience. It demonstrates the ability to enhance the stability and efficacy of other skin-benefiting ingredients, such as ceramides, and can offer skin-refatting properties in rinse-off applications.

Key findings

  1. 01 At a concentration of 0.25%, Polyglyceryl-10 Monooleate significantly decreases the interfacial tension between water and caprylic/capric triglyceride, indicating sufficient effectiveness for achieving stable emulsification. Further increasing the concentration up to 1% results in only a marginal additional reduction in interfacial tension.
  2. 02 Polyglyceryl-10 Oleate has been confirmed safe for topical application at concentrations up to 6%, demonstrating no observable skin sensitivities or irritation.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has concluded that Polyglyceryl-10 Mono/Dioleate, as part of the extensive family of polyglyceryl fatty acid esters, is safe for use in cosmetic formulations under current practices and concentrations, provided the final product is non-irritating. A prior 5% concentration limit for leave-on products was removed after higher concentrations did not induce sensitization. It is generally considered safe for cosmetic applications and complies with FDA guidelines, with an Acceptable Daily Intake (ADI) of 0–25 mg/kg body weight as a food additive by JECFA.
