Solid laundry detergent composition comprising anionic detersive surfactant and calcium-augmented technology

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:
• R1 is a aryl or heteroaryl group;
• R2 is an alkyl;
• R1 and R2 when taken together with the carbon and the nitrogen of the oxaziridinium form a ring;
• R3 is a C1 to C20 substituted alkyl;
• R4 is hydrogen, R2 or, the moiety Qt-A, wherein:
• Q is an alkylene, t=0 or 1 and A is an anionic group selected from the group consisting of OSO3−, SO3−, CO2−, OCO2−, OPO32−, OPO3H− and OPO2−;
• R5 is hydrogen, R2 or the moiety —CR11R12—X-Gb-Xc—[(CR9R10)y—O]k—R8, wherein:
• each X is independently selected from the group consisting of 0, S, N—H, or N—R8;
• and each R8 is independently selected from the group consisting of alkyl, aryl and heteroaryl, said R8 moieties having less than 21 carbons;
• each G is independently selected from the group consisting of CO, SO2, SO, PO and PO2;
• R9 and R10 are independently selected from the group consisting of H and C1-C4 alkyl;
• and R11 and R12 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 R6 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.
