Abstract
Acylated benzene sulfonated compounds with dual functionality can have the following structure: wherein each R is independently hydrogen or a C1 to C11 alkyl, each X is independently an alkali metal ion, an alkaline earth metal ion, and/or a quaternary ammonium cation, n is 1 to 3, and m is 1 to 2, with the proviso that when m is 2, the —OC(O)R groups are not located in an ortho configuration at positions 1 and 2 of the benzene ring. Cleaning compositions including the acylated benzene sulfonated compound are also disclosed.
Claims29
An acylated benzene sulfonate additive that functions as both a chelating agent and a bleach activator for cleaning compositions, the additive comprising a compound having a structure of Formula Ia:
- wherein:
- R is hydrogen or a C1 to C11 alkyl,
- each X is independently an alkali metal ion, an alkaline earth metal ion, and/or a quaternary ammonium cation, and
- n is 2 or 3.
An automatic dishwasher (ADW) detergent composition comprising:
- (i) an acylated benzene sulfonate additive that functions as both a chelating agent and a bleach activator comprising a compound having a structure of Formula Ia:
- wherein:
- R is hydrogen or a C1 to C11 alkyl,
- each X is independently an alkali metal ion, an alkaline earth metal ion, and/or a quaternary ammonium cation, and
- n is 2 or 3;
- and
- (ii) a peroxide source.
A method of cleaning glassware, dishware and/or silverware, comprising:
- supplying an automatic dishwasher (ADW) detergent composition to an automatic dishwasher including glassware, dishware and/or silverware, wherein:
- the automatic dishwasher (ADW) detergent composition comprises an acylated benzene sulfonate additive and a peroxide source, and
- the acylated benzene sulfonate additive functions as both a chelating agent and a bleach activator and comprises a compound having a structure of Formula Ia:
- wherein:
- R is hydrogen or a C1 to C11 alkyl,
- each X is independently an alkali metal ion, an alkaline earth metal ion, and/or a quaternary ammonium cation, and
- n is 2 or 3;
- and
- operating the automatic dishwasher.
