Polyglyceryl-2 Sesquioleate

Polyglyceryl-2 sesquioleate is a synthetic emulsifier derived from glycerin and oleic acid (a natural fatty acid). Its role is to stabilise oil-in-water emulsions, allowing products to combine water-soluble and oil-soluble ingredients into a uniform texture without separation.In skincare, this ingredient is used primarily in creams, serums and lotions to improve texture, spreadability and stability. It does not have a direct therapeutic effect on skin itself; rather, it enables the formulation of products that deliver other active ingredients effectively.

Polyglyceryl-2 sesquioleate has both hydrophilic (water-loving) and lipophilic (oil-loving) portions in its molecular structure. This dual affinity allows it to sit at the interface between oil and water phases, reducing surface tension and preventing them from separating. In this way, it acts as a bridge between incompatible ingredients.

This ingredient does not require special application technique; it is used by formulators during product manufacture. As a consumer, you will encounter it in creams, serums and emulsified lotions. Use products containing this ingredient as directed on the label. It is typically well-tolerated by most skin types.

Polyglyceryl-2 sesquioleate is generally well-tolerated and regarded as safe in cosmetic formulations. Some individuals with sensitivities to emulsifiers or fungal acne concerns may wish to avoid products containing this ingredient.
