Valuable / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Glyceryl Ricinoleate SE is a multifaceted monoester, distinguished by its self-emulsifying properties. It functions as a skin-conditioning agent, promoting hydration and smoothness, while simultaneously acting as a crucial stabilizer in cosmetic formulations.

Summary

emollient emulsifying skin protection surfactant

Science

Mechanism of Action

On the skin, this ingredient forms a protective barrier, acting as an emollient to significantly reduce transepidermal water loss and impart softness. Its 'SE' (self-emulsifying) grade contains specific soap molecules, enabling it to effectively stabilize oil-in-water emulsions, ensuring product consistency and optimal texture. Furthermore, it serves as a skin protection agent, decreasing cutaneous reactivity to external aggressors, and possesses mild surfactant qualities for gentle cleansing.

Stability

The 'SE' (self-emulsifying) grade incorporates water-loving soap molecules, such as sodium stearate, which significantly enhance its affinity for water and strengthen its emulsifying capabilities. It is miscible with fats and oils, dispersible in water, and crucial for stabilizing oil and water emulsions, thereby improving formulation texture and spreadability. Stability is further enhanced with the inclusion of BHT.
