A recently granted patent (Publication Number: US11911493B2) discloses a unique composition for removing nail polish while also moisturizing the hands. The composition includes a co-mixture of C2-C3 monoalcohol, glycerin, and a nail polish-removing solvent such as acetone or C2-C4 alkyl acetate(s), with acetone being essentially absent or present in minimal amounts. The glycerin to C2-C3 monoalcohol weight ratio is specified to be greater than 0.6, with water content lower than glycerin. Additionally, polyacrylamide is included in the composition to aid in the removal process.
Furthermore, the patent claims detail specific concentrations and ratios within the composition, such as the concentration of water ranging from 3% to 10% by weight, and the glycerin to C2-C4 alkyl acetate weight ratio being less than 2.0. The method of using the composition involves applying it to the nails and hands, removing the nail polish, and moisturizing the hands simultaneously. The composition is designed to be free of acetone, providing a safer and more moisturizing alternative for nail polish removal. This patent highlights a novel approach to nail care products, combining effective nail polish removal with moisturizing properties for improved hand care.
