Abstract
A laundry composition including a plurality of granules, where each of said granules has a longest dimension of no less than 3 mm and no more than 12 mm, and an aspect ratio of no more than 5, and each of said granules has a mass from 1 mg to 1 g; wherein said granules comprise 25% to 99.9% of a water soluble carrier by weight of the granules. The laundry composition also includes from 0.1% to 10% of a plurality of fine particles, by weight of the laundry composition, said fine particles having an average particle size of 0.05 μm to 50 μm.
Claims14
A laundry composition comprising:
- a plurality of granules, wherein each of said granules has a longest dimension of no less than 3 mm and no more than 12 mm, and an aspect ratio of no more than 5, and wherein each of said granules has a mass from 1 mg to 1 g;
- wherein said granules comprise 25% to 99.9% of a water-soluble carrier by weight of the granules;
- and
- from 0.1% to 10% of a plurality of fine particles, by weight of the laundry composition, said fine particles having an average particle size of 0.05 μm to 50 μm.
A laundry composition comprising:
- (i) from 10% to 90% of a plurality of first granules by weight of the laundry composition, wherein each of said first granules has a hemispherical or compressed hemispherical shape, wherein each of said first granules has a longest dimension of no less than 3 mm and no more than 12 mm, and an aspect ratio of no more than 5;
- wherein said first granules comprise:
- from 25% to 99.9%, by weight of the first granules, of a polyethylene glycol having a weight average molecular weight from 3,000 to 13,000 Daltons;
- and
- from 0.1% to 25%, by weight of the granules, of a perfume ingredient selected from free perfumes, pro-perfumes, encapsulated perfumes, perfume microcapsules, and combinations thereof;
- (ii) from 10% to 90% of a plurality of second granules by weight of the laundry composition, wherein each of said second granules has a hemispherical or compressed hemispherical shape, wherein each of said second granules has a longest dimension of no less than 3 mm and no more than 12 mm, and an aspect ratio of no more than 5;
- wherein said second granules comprise:
- from 25% to 99.9%, by weight of the second granules, of a polyethylene glycol having a weight average molecular weight from 3,000 to 13,000 Daltons,
- from 0.5% to 40%, by weight of the second granules, of an ester quaternary ammonium compound;
- and
- from 0.2% to 5%, by weight of the second granules, of a cationic polysaccharide;
- and
- (iii) from 0.1% to 10% of a plurality of fine particles by weight of the laundry composition, said fine particles having an average particle size of from 0.1 μm to 15 μm, wherein said fine particles are selected from the group consisting of zeolite, fume silica, precipitated silica, calcium carbonate, titanium dioxide, magnesium carbonate, clays, kaolins, calcium stearate, magnesium stearate, starch, and combinations thereof.
A method of making a laundry composition, comprising the step of:
- a. providing a viscous material comprising from 40% to 99% by weight of the composition of polyethylene glycol, wherein said polyethylene glycol has a weight average molecular weight from 3,000 to 13,000 Daltons,
- b. passing said viscous material through small openings and onto a moving conveyor surface upon which said viscous material is cooled to form a plurality of granules, and
- c. mixing the plurality of granules with a plurality of fine particles having an average particle size of from 0.1 μm to 15 μm, to form said laundry composition.
