Phytosteryl/Octyldodecyl Lauroyl Glutamate
Phytosteryl/Octyldodecyl Lauroyl Glutamate is a skin-friendly, plant-derived emollient and hair conditioner used in many UK moisturisers, serums and haircare products. It helps soften skin and hair while leaving a smooth, non-greasy feel. Gentle enough for sensitive skin, it is often found in premium natural and clean-beauty formulas.
How it works in skincare
In cosmetics and skincare, Phytosteryl/Octyldodecyl Lauroyl Glutamate functions as a highly skin-compatible emollient and conditioning agent. It is formed by combining plant sterols with an amino acid derivative, creating a molecule that mimics the skin’s natural lipids. This allows it to integrate seamlessly into the skin’s barrier, delivering softness and smoothness while helping to reduce transepidermal water loss without a heavy or occlusive feel. In haircare it coats the hair shaft lightly to improve manageability and shine.
