Abstract:
A liquid dishwashing detergent composition suitable for use in hand dishwashing, said composition comprising:(a) a low molecular weight organic diamine having a pK1 and a pK2, wherein the pK1 and the pK2 of said diamine are both in the range of from 8.0 to 115; (b) an anionic surfactant; (c) an amphoteric surfactant, (d) a solvent selected from the group consisting of a diol, a polymeric glycol, and mixtures thereof, wherein said diol is represented by the formula: â€ƒwherein n=0-3, R7=H, methyl or ethyl; and R8=H, methyl, ethyl, propyl, isopropyl, butyl and isobutyl; and wherein the polymeric glycol is represented by the formula: (PO)x(EO)yH wherein PO represents a propylene oxide group and EO represents an ethylene oxide group and x+y is from 17 to 68, and x/(x+y) is from 0.25 to 1.0; wherein the pH as measured as 10% aqueous solution is from 5.0 to 12.5; and wherein the mole ratio of said anionic surfactant to said amphoteric surfactant to said diamine is from 100:40:1 to 9:05:1.
