polyhydroxystearic acid

Description

Polyhydroxystearic acid is a versatile and effective ingredient in skincare formulations, derived from the natural fatty acid stearic acid. This polymer functions primarily as an emollient and dispersing agent, enhancing the texture and stability of various cosmetic products. Its molecular structure allows it to form a protective barrier on the skin's surface, helping to reduce transepidermal water loss and improve hydration.

In formulations, polyhydroxystearic acid excels at dispersing inorganic UV filters and pigments, making it particularly valuable in sunscreens and color cosmetics. It aids in creating smooth, even applications and prevents the agglomeration of particles. This ingredient is also known for its ability to improve the spreadability of formulas, contributing to a more pleasant sensory experience for users.

Polyhydroxystearic acid is generally well-tolerated by most skin types and is considered non-comedogenic. It can be found in a wide range of products, including foundations, BB creams, and moisturizers. Its compatibility with various cosmetic ingredients makes it a popular choice among formulators seeking to enhance product stability and performance without compromising skin health or comfort.
