Patent ID: 7910533

Claim:
A solid laundry detergent composition in particulate form, comprising: (a) anionic detersive surfactant; (b) a calcium-augmented technology comprising a bleach boosting ingredient having a structure corresponding to Formula 2 below: wherein: R 1 is a aryl or heteroaryl group; R 2 is an alkyl; R 1 and R 2 when taken together with the carbon and the nitrogen of the oxaziridinium form a ring; R 3 is a C 1 to C 20 substituted alkyl; R 4 is hydrogen, R 2 or, the moiety Q t -A, wherein: Q is an alkylene, t=0 or 1 and A is an anionic group selected from the group consisting of OSO 3 − , SO 3 − , CO 2 − , OCO 2 − , OPO 3 2− , OPO 3 H − and OPO 2 − ; R 5 is hydrogen, R 2 or the moiety —CR 11 R 12 —X-G b -X c —[(CR 9 R 10 ) y —O] k —R 8 , wherein: each X is independently selected from the group consisting of 0, S, N—H, or N—R 8 ; and each R 8 is independently selected from the group consisting of alkyl, aryl and heteroaryl, said R 8 moieties having less than 21 carbons; each G is independently selected from the group consisting of CO, SO 2 , SO, PO and PO 2 ; R 9 and R 10 are independently selected from the group consisting of H and C 1 -C 4 alkyl; and R 11 and R 12 are independently selected from the group consisting of H and alkyl, or when taken together may form a carbonyl; b=0 or 1; c can=0 or 1, but c must=0 if b=0; y is an integer from 1 to 6; k is an integer from 0 to 20; and R 6 is H, or an alkyl, aryl or heteroaryl moiety; (c) from 0% to less than 5%, by weight of the composition, of zeolite builder; (d) from 0% to less than 5%, by weight of the composition, of phosphate builder; (e) optionally, from 0% to less than 5%, by weight of the composition, of silicate salt; a polyaminoamide having a structure corresponding to the formula where EO represents an ethylene oxide unit and x is from 21 to 100; (g) magnesium sulfate; and (h) an effervescence system.
