A laundry particle comprising:
- a) a porous carrier selected from the group consisting of zeolite X, zeolite Y, and mixtures thereof;
- and
- b) one or more laundry agents, said laundry agents selected from:
- i) from about 5% to about 100% by weight, of one or more deliverable agents, said deliverable agents having a volume/surface area ratio versus cross sectional area defined by the formula:
- y+0.01068x.ltoreq.1.497
- wherein x is the molecular cross sectional area and y is the molecular volume/surface area ratio;
- ii) from 5% to about 95% by weight, of one or more non-deliverable agents, said non-deliverable agents having a volume/surface area ratio versus cross sectional area defined by the formula:
- y+0.01068x>1.497
- wherein x is the molecular cross sectional area and y is the molecular volume/surface area ratio;
- provided said laundry agents do not comprise greater than 6% of the mixture comprising:
