Diisostearate
What is Diisostearate?
Diisostearate is derived from diisostearic acid, a dicarboxylic acid formed by dimerizing isostearic acid sourced from tall oil fatty acids or vegetable oils like oleic acid. This branched-chain structure gives it surfactant properties ideal for cosmetic use. Primarily functioning as an emulsifying agent, it reduces surface tension to mix immiscible oil and water phases, creating stable emulsions in products such as lotions, creams, deodorants, and sunscreens. This stabilization prevents phase separation, improves spreadability, and enhances texture for a smooth application. Its lipophilic nature allows effective incorporation into oil-based or anhydrous formulations, supporting consistent performance across various personal care items without altering skin feel significantly.
