Polish remover formulations

1. A method for promoting the polish removing performance of a polish remover formulation, comprising including a blend comprising at least two glycerol ketal derivatives of formula I below:

wherein:

R1 and R2, independently from one another, are selected in the group consisting of: hydrogen or a linear or branched C1-C12 alkyl, a C4-C12 cycloalkyl or an aryl, and

R3 is H, a linear or branched alkyl, a cycloalkyl or a C(═O)R4 group, with R4 being a linear or branched C1-C4 alkyl or a C5-C6 cycloalkyl,

as solvent in the polish remover formulation, wherein the formulation also comprises water.

2. A method according to claim 1 , wherein R1 and R2, independently from one another, are selected in the group consisting of methyl, ethyl, isopropyl, n-propyl, isobutyl, n-butyl, tert-butyl, n-pentyl, cyclopentyl, cyclohexyl, and phenyl.

3. A method according to claim 1 , wherein R3 is H or a C(═O)R4 group, and R4 is methyl, ethyl, isopropyl, n-propyl, isobutyl, n-butyl, or tert-butyl.

4. A method according to claim 1 , wherein the blend is a mixture of 2 or 3 glycerol ketal derivatives of formula I.

5. A method according to claim 1 , wherein the blend is a mixture of 2 glycerol ketal derivatives selected in the group consisting of 2,2-dimethyl-1,3-dioxolane-4-methanol, 2,2-diisobutyl-1,3-dioxolane-4-methanol, 2-isobutyl-2-methyl-1,3-dioxolane-4-methanol, 2-isopropyl-1,3-dioxolane-4-methanol, 2-butyl-2-ethyl-1,3-dioxolane-4-methanol, 2-phenyl-1,3-dioxolane-4-methanol and 2-methyl-2-phenyl-1,3-dioxolane-4-methanol, 2,2-dimethyl-1,3-dioxolane-4-acetate, (2-(heptan-3-yl)-1,3-dioxolan-4-yl)methanol, and mixtures thereof.
