Science
Mechanism of Action
This saccharide ester possesses both hydrophilic (sucrose) and lipophilic (fatty acid) components, making it amphipathic. This dual nature allows it to bridge oil and water phases, effectively emulsifying formulations. On the skin, its emollient properties contribute to a smoother texture and improved hydration. Furthermore, sucrose esters like Sucrose Acetate/Stearate have a general capacity to enhance the penetration of other active ingredients into the skin, optimizing overall product performance.

Stability
Sucrose Acetate/Stearate maintains stability within a pH range of 4 to 8. Exposure to pH levels outside this range (below 4 or above 8) may lead to saponification, a hydrolysis of the ester bond. It demonstrates robust stability under conditions of weak acids or bases, enhances high-temperature stability in formulations, and is broadly compatible with performance ingredients, fragrances, acids, and bases.
Synergies
- Enhances penetration of other active ingredients
Conflicts
- Saponification occurs outside pH 4-8
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed saccharide esters, including Sucrose Acetate/Stearate, safe for use in cosmetics under current practices. While specific usage concentrations for Sucrose Acetate/Stearate itself were not reported in industry surveys, related ingredients such as Sucrose Stearate and Sucrose Palmitate demonstrated tolerability on human skin at concentrations up to 2% in nanoemulsions. Sucrose Stearate is also recognized as generally safe by the U.S. FDA.
