Isopentyldiol
What is Isopentyldiol?
Isopentyldiol is a synthetic diol, a type of alcohol with two hydroxyl groups, derived from petrochemical processes. It appears as a clear, colorless, odorless liquid commonly used in skincare, haircare, and cosmetic formulations. Primarily functioning as a solvent, it dissolves both water-soluble and oil-soluble ingredients, enabling stable product textures and controlled release of active components. As a humectant, it attracts and binds moisture to the skin and hair surface, promoting hydration without greasiness. Its low viscosity helps reduce the thickness of formulations, improving spreadability and absorption. In hair products, it penetrates the cuticle to support fiber integrity. Overall, it enhances product performance across lotions, serums, shampoos, and conditioners by balancing evaporation rates and boosting solubility.
