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): (R 1 3 SiO 1/2 )(R 1 R 3 SiO 2/2 )(R 1 3 SiO 1/2 ) (I). In formula (I), each R 1 is an independently selected hydrocarbyl group. R 3 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.

Claims (22)

1. A detergent composition comprising a) a dispersant comprising propylene glycol;

b) an anionic surfactant;

c) a nonionic surfactant; and

d) a trisiloxane of the following general formula (I):

(R 1 3 SiO 1/2 )(R 1 R 3 SiO 2/2 )(R 1 3 SiO 1/2 )  (I);

wherein each R 1 is an independently selected hydrocarbyl group and R 3 is selected from the following groups (i) to (iii) and (v) to (x);

2. The detergent composition as set forth in claim 1 , wherein each R 1 is an independently selected C 1 -C 6 alkyl group.

3. The detergent composition as set forth in claim 1 , wherein the dispersant is present in an amount of from about 0.01 to about 50, alternatively in an amount of from about 0.1 to about 40, part(s) by weight, based on 100 parts by weight of the detergent composition.

4. The detergent composition as set forth in claim 1 , further comprising water and further defined as an aqueous detergent composition.

5. The detergent composition as set forth in claim 1 , further comprising at least one surfactant.

6. The detergent composition as set forth in claim 1 , further defined as a dishwashing detergent composition, a laundry detergent composition, a stain removal/pre-treatment composition, or a hard surface cleaning composition.

7. The detergent composition as set forth in claim 2 , wherein each R 1 is a methyl group.

8. The detergent composition as set forth in claim 1 , wherein R 3 is group (i).

9. The detergent composition as set forth in claim 1 , wherein R 3 is group (ii).

10. The detergent composition as set forth in claim 1 , wherein R 3 is group (iii).

11. The detergent composition as set forth in claim 1 , wherein R 3 is group (v).

12. The detergent composition as set forth in claim 1 , wherein R 3 is group (vi).

13. The detergent composition as set forth in claim 1 , wherein R 3 is group (vii).

14. The detergent composition as set forth in claim 1 , wherein R 3 is group (viii).

15. The detergent composition as set forth in claim 1 , wherein R 3 is group (ix).

16. The detergent composition as set forth in claim 1 , wherein R 3 is group (x).

17. The detergent composition as set forth in claim 6 , further defined as an auto dishwashing (ADW) detergent composition.
