Dishwashing detergent compositions containing organic diamines

A detergent composition suitable for use in hand dishwashing, said composition comprising:

• a) from about 0.1% to about 5% by weight of an organic diamnine having a molecular weight less than or equal to 400 g/mol;
• b) from about 5% to about 50% by weight of an anionic surfactant;
• c) from about 0.5% to about 10% by weight of an amine oxide surfactant;
• d) from about 0.001% to about 2% by weight of a perfume;
• e) from about 0.01% to about 5% by weight of a polymeric suds stabilizer selected from the group consisting of:
• i) homopolymers of (N,N-dialkylamino)alkyl acrylate esters having the formula:
• wherein 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
• wherein R1 is as described above;
• provided that the ratio of ii) to i) is from about 2:1 to about 1:2;
• and wherein said polymer suds stabilizer has a molecular weight of from about 1,000 to about 2,000,000 daltons;
• wherein said composition contains less than about 5% by weight of magnesium and calcium salts;
• 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 amine oxide to said diamine is from about 27:8:1 to about 11:3:1.
