POLYGLYCERYL-10 HEPTAOLEATE.

Valuable CAS 103175-09-3 / SKIN CONDITIONING

Polyglyceryl-10 Heptaoleate is a versatile polyglyceryl ester that functions primarily as an emulsifier and surfactant, stabilizing oil and water phases in cosmetic formulations. It also acts as a skin conditioning agent, providing moisturizing and softening benefits to enhance skin smoothness and elasticity.

Summary

Emulsifying Skin Conditioning Surfactant Emollient Cleansing Agent

Science

Mechanism of Action

This ingredient works by reducing the interfacial tension between immiscible oil and water components, thereby creating stable emulsions essential for creams, lotions, and other formulations. Beyond its role in binding ingredients, Polyglyceryl-10 Heptaoleate functions as an emollient, moisturizing the skin, enhancing its smoothness, and promoting elasticity. It further aids in strengthening the skin's natural barrier function by retaining essential moisture and preventing transepidermal water loss. As a gentle surfactant, it effectively boosts the cleansing power of products, making it suitable even for sensitive skin.

Key findings

  1. 01 Studies on Polyglyceryl-10 Monooleate demonstrated significant reduction in interfacial tension at concentrations as low as 0.25% (wt/wt), improving emulsification stability, with further benefits observed up to 1%. This indicates the potential for stable formulations, including low-viscosity products and liposomal structures.
  2. 02 Research on Polyglyceryl-10 monocaprylate revealed its ability to self-assemble into transparent nanoparticles in water, effectively removing makeup like pen eyeliner at 2.5-10 wt%. Notably, it was found to be less irritating than PEG-6 caprylic/capric glycerides, highlighting its suitability for gentle cleansing applications.

Stability

Polyglyceryl-10 Heptaoleate is anticipated to be a stable oil-in-water emulsifier. Related polyglyceryl esters exhibit robust thermal and cold stability, alongside effective emulsification capabilities even under acidic conditions. It functions as a hydrophilic, nonionic surfactant with notable resistance to salts and acids. While specific solubility for Heptaoleate is categorized as 'both', related compounds like Polyglyceryl-10 Oleate show varying solubility in water (dispersible in hot, less so in cold) but are soluble in alcohols, vegetable oils, and silicones, indicating its amphiphilic nature and versatility in diverse formulation bases.
