Isostearic Acid

Isostearic Acid

Isostearic Acid is a branched chain fatty acid that is derived from the hydrolysis of a naturally occurring wax, such as jojoba oil. It is commonly used in the cosmetic and personal care industry as a emollient, surfactant, and thickening agent. Due to its unique branched structure, it enhances the stability and texture of cosmetic products, making them feel smoother and more luxurious on the skin. Additionally, it is also used in the production of lubricants, plastics, and other industrial applications.
