A composition, comprising:
- at least one silicate builder;
- and
- at least one ester of the formula:
- 6
- wherein R1 is an alkyl group, R2 is an alkyl group, and R3 is hydrogen, a halogen, a metal, or an unsubstituted or substituted ammonium cation.
A detergent composition, comprising:
- an effective amount of at least one silicate builder;
- and
- at least about 25 wt % of at least one ester of the formula:
- 7
- wherein R1 is an alkyl group, R2 is an alkyl group, and R3 is hydrogen, a halogen, a metal, or an unsubstituted or substituted ammonium cation.
A powdered detergent composition, comprising:
- about 20 wt % to about 30 wt % of at least one silicate builder;
- and
- at least about 35 wt % of at least one ester of the formula:
- 8
