Abstract:
A hand dishwashing detergent 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 about 8.0 to about 11.5; b) an anionic surfactant; c) an amine oxide; d) magnesium ions; and e) a polymeric suds stabilizer selected from the group consisting of: i) homopolymers of (N,N-dialkylamino)alkyl acrylate esters having the formula: â€ƒwherein each R is independently hydrogen, C1-C8 alkyl, and mixtures thereof, R1 is hydrogen, C1-C6 alkyl, and mixtures thereof, n is from 2 to about 6; and ii) copolymers of (i) and â€ƒwherein R1 is hydrogen, C1-C6 alkyl, and mixtures thereof; provided that the ratio of (ii) to (i) is from about 2 to 1 to about 1 to 2; and wherein said polymeric suds stabilizer has a molecular weight of from about 1,000 to about 2,000,000 daltons; wherein the pH as measured as 10% aqueous solution is from about 5.0 to about 12.5; wherein said magnesium ions are present at an equimolar or less than equimolar amount of said diamine; and wherein the mole ratio of said anionic surfactant to said amine oxide to said diamine is from about 100:40:1 to about 9:0.5:1.
