HYDROXYPROPYL DIMETHICONE STEARATE

Description

Hydroxypropyl Dimethicone Stearate is a multifunctional silicone-based ingredient widely used in skincare and cosmetic formulations. This compound is a hybrid of dimethicone, a silicone oil, and stearic acid, a fatty acid, combined with hydroxypropyl groups. Its unique structure imparts both hydrophobic and hydrophilic properties, making it an excellent emollient and emulsifier.

In skincare products, Hydroxypropyl Dimethicone Stearate acts as a conditioning agent, providing a smooth, silky feel to the skin without leaving a greasy residue. It forms a protective barrier on the skin's surface, helping to reduce transepidermal water loss and improve skin hydration. This ingredient also enhances the spreadability of formulations, contributing to a more even application of products.

Hydroxypropyl Dimethicone Stearate is particularly beneficial in sun care products, as it can improve the water resistance of sunscreens. It also aids in the dispersion of pigments and other active ingredients, ensuring a more uniform distribution within the formulation. Due to its low irritation potential and compatibility with various skin types, this ingredient is suitable for use in sensitive skin products.
