GLYCERETH-17 POLYHYDROXYSTEARATE

Description

Glycereth-17 Polyhydroxystearate is a versatile emulsifier and thickening agent widely used in cosmetic and skincare formulations. This synthetic ingredient is derived from glycerin and stearic acid, combining the hydrating properties of glycerin with the emollient characteristics of fatty acids. Its primary function is to stabilize oil-in-water emulsions, creating smooth and consistent textures in various products such as lotions, creams, and sunscreens.

The "17" in its name refers to the average number of ethylene oxide units added to glycerin, while "polyhydroxystearate" indicates multiple hydroxyl groups attached to a stearate chain. This unique structure allows Glycereth-17 Polyhydroxystearate to effectively bridge the gap between oil and water phases in formulations, promoting long-term stability and preventing separation.

In addition to its emulsifying properties, this ingredient contributes to the overall feel of products, imparting a silky, non-greasy texture. It is particularly valuable in formulations requiring enhanced spreadability and a light skin feel. Glycereth-17 Polyhydroxystearate is generally well-tolerated by most skin types and is considered safe for use in cosmetic applications when used at appropriate concentrations.
