Isostearic Acid is an exceptionally mild, odor-free liquid fatty acid that offers a light, lubricious feel and can be used in an extensive, broad range of cosmetic applications. This ingredient provides excellent superfatting properties, a light, elegant feel, and low viscosity.

Isostearic Acid has been shown to increase SPF in sunscreen emulsions using solid or liquid filters. It also offers film-forming properties, making it an ideal ingredient in hot and cold-process soap emulsions, liquid cleansers, and shaving soaps.

Isostearic Acid is a safe and eco-friendly ingredient. It is cold-processable, vegetable-derived, and biodegradable. It is used in cleansing applications, sun care, moisturizers, and decorative cosmetics.
