Acetylated Sucrose Distearate

Acetylated sucrose distearate is a modified sugar derivative created by combining sucrose (table sugar) with stearic acid, a naturally occurring fatty acid found in plants and animals. The acetylation process—a chemical modification—makes it more stable and compatible with cosmetic formulations.

In skincare products, this ingredient functions as an emollient and skin conditioner. It works by coating the skin's surface to improve texture, smoothness and hydration feel, making it a common choice in creams, lotions and moisturisers.

Acetylated sucrose distearate is an occlusive—it sits on the skin's surface and creates a protective barrier that slows water loss. This helps maintain hydration levels, which is particularly useful in moisturising formulations.

Unlike heavier oils, this ingredient tends to have a lighter feel because of its molecular structure, making it suitable for products intended to condition without leaving a sticky or heavy residue.

This ingredient is typically found in rinse-off or leave-on moisturising products; you do not need to apply it in a specific way beyond using your product as directed. It works well in layered routines and is unlikely to interact negatively with other skincare ingredients. If you are using multiple moisturising products, observe how your skin responds to the overall hydration level.
