Abstract: A detergent composition comprises a trisiloxane having at least one carbinol functional group. The trisiloxane comprises the reaction product of (A) an initial trisiloxane and (B) an organic compound. Component (A) has a pendant silicon-bonded functional group selected from a hydrogen atom, an epoxy-containing group, an ethylenically unsaturated group, and an amine group. Typically, component (A) is free of certain terminal silicon-bonded functional groups and is free of polyoxyalkylene groups. Component (B) has a functional group reactive with the pendant silicon-bonded functional group of component (A), and has at least one hydroxyl functional group. The trisiloxane may be of the following general formula (I): (R13SiO1/2)(R1R3SiO2/2)(R13SiO1/2) (I). In formula (I), each R1 is an independently selected hydrocarbyl group. R3 may be selected from the groups (i) to (x) described herein, each of the groups having at least one carbinol group. Typically, the trisiloxane has 1-6 carbinol groups.
