Science
Mechanism of Action
This ingredient acts primarily as a solvent, facilitating the dissolution of various substances in a cosmetic product. It functions as an astringent, providing a temporary skin-tightening effect, and serves as a viscosity-controlling agent. Its quick evaporation helps neutralize excess oil, imparting a smooth, matte skin feel, and its ethanol component may increase the penetration of other ingredients.

Hydroalcoholic formulations incorporating this ingredient are inherently resistant to microbial growth. Cosmetic products containing denatured alcohol have demonstrated adequate stability over standard 4-week testing periods.
Safety
Safety Profile
SD Alcohol 38-F is denatured ethyl alcohol, formulated according to 27CFR21 with specific agents including thymol, chlorothymol, menthol, and either boric acid or polysorbate-80. While the Cosmetic Ingredient Review (CIR) Expert Panel has evaluated other denatured alcohols, determining safety based on their denaturants, a direct CIR assessment for SD Alcohol 38-F with its unique denaturant blend was not explicitly identified in the provided data. Therefore, its specific safety profile regarding these denaturants remains formally unreviewed by CIR.
