LAUNDRY DETERGENT FORMULATION
An improved binder for use in making laundry detergent compositions, more specifically bleach activator granules, is described. The binder utilizes glycerin as a replacement for fatty acids in the overall granule mixture which improves solubility and reduces odor.
1 . A process for the preparation of bleach activator granules, the process comprising the step of extruding a mixture comprising a bleach activator and a binder, said binder comprising an anionic or nonionic surfactant, a polyglycol and glycerin.
2 . A process according to claim 1 wherein said binder does not contain a fatty acid.
3 . A process according to claim 1 wherein said binder further comprises afatty acid.
4 . A process according to claim 1 wherein said bleach activator is selected from the group consisting of TAED, NOBS, iso-NOBS, DOBA, LOBS, DOBS, GOBS, and NOBA.
5 . A process according to claim 3 wherein said bleach activator is selected from the group consisting of TAED, NOBS, iso-NOBS, DOBA, LOBS, DOBS, GOBS, and NOBA.
6 . A process according to claim 1 wherein the total mixture comprises, by weight, 50%-95% bleach activator, 0.1%-18% anionic or nonionic surfactant, 1.0% to 23% polyglycol, and 0.5%-19.0% glycerin.
7 . A process according to claim 3 wherein the total mixture comprises, by weight, 50%-95% bleach activator, 0.1%-18% anionic or nonionic surfactant, 1.0% to 23% polyglycol, 0.5%-19.0% glycerin and 0.01%-8.0% fatty acid.
8 . A laundry detergent composition comprising:
a bleach activator, and
a binder, said binder comprising an anionic or nonionic surfactant, a polygycol and glycerin.
9 . A laundry detergent composition according to claim 8 wherein said binder does not contain a fatty acid.
10 . A laundry detergent composition according to claim 8 wherein said binder further comprises a fatty acid.
11 . A laundry detergent composition according to claim 8 wherein said bleach activator is selected from the group consisting of TAED, NOBS, iso-NOBS, DOBA, LOBS, DOBS, GOBS and NOBA.
12 . A laundry detergent composition according to claim 10 wherein said bleach activator is selected from the group consisting of TAED, NOBS, iso-NOBS, DOBA, LOBS, DOBS, OOBS, and NOBA.
13 . A laundry detergent composition according to claim 8 wherein the composition comprises, by weight, 50%-95% bleach activator, 0.1%-18% anionic or nonionic surfactant, 1.0% to 23% polyglycol, and 0.5%-19.0% glycerin.
14 . A laundry detergent composition according to claim 10 wherein the composition comprises, by weight, 50%-95% bleach activator, 0.1%-18% anionic or nonionic surfactant, 1.0% to 23% polyglycol, 0.5%-19.0% glycerin and 0.01%-8.0% fatty acid.
