Abstract:
An automatic dishwashing composition comprising:(a) from about 5% to about 90% by weight of the composition of a builder;(b) from about 0.1% to about 15% by weight of the composition of a mixed surfactant system, wherein said mixed surfactant system comprises one or more low cloud point nonionic surfactants having a cloud point of less than 30.degree. C. and one or more charged, foam producing surfactants selected from the group consisting of anionic surfactants, zwitterionic surfactants and mixtures thereof, the ratio of low cloud point nonionic surfactant to charged, foam producing surfactant being within the range of from about 20:1 to about 1:5;(c) optionally, from about 0.1% to about 40% by weight of the composition of a bleaching agent;(d) adjunct materials; andwherein the mixed surfactant system dissolves in water having a hardness of 1.246 mmol/L under dishwashing conditions with a interfacial tension of less than 4 Dynes/cm at 45.degree. C.
