Science
Mechanism of Action
This ester conditions the skin by providing emollience, which translates to enhanced softness and a nourished feel. It is believed to create a delicate, non-occlusive film on the epidermal surface, thereby aiding in the reduction of moisture loss. Furthermore, it significantly improves the sensory experience of cosmetic formulations by promoting smooth spreadability and contributing to a luxurious, silky, non-greasy after-feel. Its oil-soluble nature also suggests a capacity to aid in the uniform dispersion of other oil-soluble active compounds and pigments within a formula.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed alkyl esters, including Heptylundecyl Hydroxystearate, safe for use under current practices and concentrations, provided formulations are non-irritating. While a specific maximum concentration for this compound is not available, similar hydroxystearic acid derivatives have been reported in leave-on products at up to 28% (Octyldodecyl Stearoyl Stearate), in lipsticks at 14.2% (Polyhydroxystearic Acid), and in other makeup formulations at 13.2% (Hydroxystearic acid).
