Science
Mechanism of Action
On the skin, SD Alcohol 23-F functions to effectively dissolve other components within a formulation, thereby creating an elegant and swift-drying finish. It also acts as a penetration enhancer, facilitating the deeper absorption of active ingredients. Beyond these roles, it offers astringent properties that provide a refreshing sensation and a temporary skin-tightening effect. Its antimicrobial qualities aid in skin disinfection, and it can also serve as a preservative, though it is notably associated with a drying effect on the skin.

Stability
Ethanol, the principal component of SD Alcohol 23-F, is a volatile compound, requiring formulation strategies to control evaporation and maintain product stability. It is also flammable.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of denatured alcohols, including specially denatured (SD) alcohols, when utilized in cosmetic formulations. The safety assessment considers the denaturing agents, which are present at low concentrations. SD Alcohol 23-F is specifically denatured with salicylic acid, resorcinol, and bergamot or bay oil, all of which have undergone independent safety evaluations by the CIR Expert Panel. The FDA regulates SD alcohol denaturing processes under 27CFR21. While the SCCS has not issued an opinion on ethanol, high margins of safety are anticipated.
