摘要

Automatic dishwashing detergent compositions comprising: a) 5 % to 90 % by weight of builder; b) 0.1 % to 15 % by weight of: I) a surfactant of the formula R1(EO)a(PO)b(BO)c, wherein R1 is a linear or branched C6 to C20 alky l; a is from 2 to 30; b is from 0 to 30; c is from 1 to 30; and said surfactant has an X/Y number less than 1.90; and or ii) a surfactant of the formula R1O[CH2CH(R3)O]eR2, wherein R1 is a hydrocarbon radical having from 1 to 30 carbon atoms; R2 is a hydrocarbon radical having 1 to 30 carbon atoms; R3 is H, or a linear aliphatic hydrocarbon radical having from 1 to 4 carbon atoms ; e is an integer having an average value from 1 to 40; c) optionally, from 0. 1 % to 40 % by weight of a bleaching agent and d) adjunct materials, such as enzymes, surfactants other than (b), or chelating agents.
