Science
Mechanism of Action
Methoxyisopropanol functions by dissolving other cosmetic ingredients, thereby acting as a solvent. Additionally, it serves as a viscosity decreasing agent, which helps to improve the texture and spreadability of formulations.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded Methoxyisopropanol is safe for use in nail care products at concentrations up to 35%. Dermal exposure studies have indicated it is non-irritating to slightly irritating and non-sensitizing to the skin. While the FDA lists it as an indirect food additive (for adhesives), Canada's Cosmetic Ingredient Hotlist indicates potential safety issues for its isomer, 2-methoxypropanol (CAS: 1589-47-5), restricting its use to a maximum of 0.5%.
