10-HYDROXYSTEARIC ACID

Description

10-Hydroxystearic acid is a naturally occurring fatty acid derivative found in various plant oils and animal fats. This versatile ingredient plays a crucial role in skincare formulations due to its unique chemical structure and beneficial properties. As a hydroxy fatty acid, it combines the characteristics of both fatty acids and hydroxy compounds, offering enhanced functionality in cosmetic products.

The molecule consists of an 18-carbon chain with a hydroxyl group attached at the tenth carbon position, giving it both hydrophilic and lipophilic properties. This amphiphilic nature allows 10-hydroxystearic acid to act as an effective emulsifier, stabilizing oil-in-water and water-in-oil emulsions in skincare formulations. It also functions as a thickening agent, improving the texture and consistency of creams and lotions.

In addition to its formulation benefits, 10-hydroxystearic acid exhibits mild antimicrobial properties, contributing to product preservation. Its emollient properties help to soften and smooth the skin, while its occlusive nature aids in reducing transepidermal water loss. These attributes make 10-hydroxystearic acid a valuable ingredient in moisturizers, barrier creams, and other skincare products designed to improve skin hydration and texture.
