Hydroxystearic Acid

Description

Hydroxystearic acid is a multifunctional ingredient derived from the hydrogenation of oleic acid, a naturally occurring fatty acid found in various plant oils. This white, waxy solid is widely utilized in skincare and cosmetic formulations due to its versatile properties. As an emollient, it helps to soften and smooth the skin, improving its texture and appearance. Hydroxystearic acid also functions as an effective emulsifier, aiding in the stable combination of oil and water-based components in product formulations.

The ingredient demonstrates excellent thickening and stabilizing capabilities, contributing to the desired consistency and shelf-life of skincare products. Its mild nature makes it suitable for use in formulations designed for sensitive skin types. Hydroxystearic acid can enhance the spreadability of creams and lotions, promoting even application and improved product performance.

In addition to its cosmetic benefits, hydroxystearic acid exhibits some antimicrobial properties, potentially contributing to the preservation of formulations. Its ability to form a protective barrier on the skin's surface helps to reduce transepidermal water loss, supporting skin hydration and overall skin health. These attributes make hydroxystearic acid a valuable component in a wide range of skincare products, including moisturizers, sunscreens, and anti-aging formulations.
