Pentaerythrityl Distearate description

Pentaerythrityl distearate is a chemical compound formed through the esterification (reacting an acid with an alcohol) of pentaerythritol with stearic acid, a long-chain fatty acid. In skin care preparations, it serves as a formula emulsifier and emollient. Due to its emollient nature, pentaerythrityl distearate helps prevent water loss and softens skin, allowing it to maintain a healthy, hydrated look. Pentaerythrityl distearate is best used as a part of a well-rounded skin care routine that contains other skin-replenishing and skin-restoring ingredients. In its raw material form, this emulsifying agent is an off-white wax-like substance. Usage levels in cosmetics range from 1–5%.
