Isostearic Acid

Description

Isostearic Acid is a versatile fatty acid derived from natural sources, predominantly vegetable oils. This branched-chain aliphatic acid plays a crucial role in cosmetic and skincare formulations due to its unique properties. With a molecular structure that imparts both hydrophobic and hydrophilic characteristics, Isostearic Acid functions as an effective emollient and emulsifier.

In skincare products, Isostearic Acid serves multiple purposes. It acts as a thickening agent, enhancing the texture and stability of creams and lotions. Its emollient properties help to soften and smooth the skin, reducing roughness and improving overall skin feel. As an emulsifier, it aids in blending oil and water-based ingredients, creating stable and homogeneous formulations.

Isostearic Acid also exhibits mild cleansing properties, making it suitable for use in gentle cleansing products. Its ability to form clear solutions with many cosmetic ingredients makes it valuable in transparent formulations. Additionally, this fatty acid can function as a co-emulsifier, enhancing the performance of other emulsifying agents in complex formulations. Its low irritation potential and compatibility with various skin types contribute to its widespread use in skincare products.
