Abstract
Antimicrobial detergent compositions especially suitable for manual diswashing comprise 0.001-2% iodine ions complexed with an amphoteric surfactant, 5-90% uncomplexed surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, amphoteric surfactants and mixture thereof, and 5-50% water. The detergent compositions have pH of 7-10. Preferably at least a portion of the iodine ions are added as an iodine in the form of a compound selected from the group consisting of KI, NaI, KOI, NaOI and Ca(0I)2.

A light duty liquid detergent composition characterized by weight of the composition:
- (1) from 0.001% to 2.0% of iodine ions, characterized in that at least a portion of the iodine ions are complexed iodine that is complexed with a complexing surfactant selected from the group consisting of amido propyl betaines, derivatives of aliphatic or heterocylclic secondary and tertiary amines, semi-polar nonionic surfactants, alcohol ethoxylates and mixtures thereof;
- (2) from 5% to 90% of an uncomplexed surfactant selected form the group consisting of anionic surfactants, nonionic surfactants, semi-polar nonionic surfactants and mixtures thereof;
- and
- (3) from 5% to 50% water;
- characterized in that the light duty liquid detergent composition has a pH of between 7 and 10.
