Abstract
A treatment composition including a plurality of first particles. Each first particle having from greater than 2% to about 50%, by weight of each first particle, of an antioxidant. Each first particle further having a water-soluble first carrier. Each first particle having less than 20%, by weight of each first particle, of polyvinyl alcohol.
Claims18
A treatment composition comprising a plurality of first particles, wherein:
- each first particle comprises a solid matrix and an antioxidant disposed in the solid matrix,
- the solid matrix comprises a water-soluble first carrier,
- the antioxidant is present in an amount of from about 5% to about 50% by weight of each first particle,
- the antioxidant comprises a hindered phenol selected from the group consisting of 2,6-bis(1,1-dimethylethyl)-4-methyl-phenol;
- C1-C18 linear or branched alkyl esters of 3,5-bis(1,1-dimethylethyl)-4-hydroxy-benzenepropanoic acid;
- and mixtures thereof,
- each first particle comprises less than about 20%, by weight of each first particle, of polyvinyl alcohol,
- the first particle is free of diacyl peroxide, and
- the treatment composition is configured to deposit at least about 189 micrograms of the antioxidant per gram of fabric.
A treatment composition comprising:
- a. a plurality of first particles, each first particle comprising a solid matrix and an antioxidant disposed in the solid matrix, wherein the solid matrix comprises a water-soluble first carrier, wherein the antioxidant is present in an amount of from about 10% to about 50%, by weight of the plurality of first particles;
- and
- b. a plurality of second particles, each second particle comprising a solid matrix and a second particle surfactant disposed in the solid matrix, wherein the solid matrix comprises a water-soluble second carrier;
- wherein the ratio of second particle surfactant to antioxidant in the treatment composition is at least 1:1,
- wherein the first particle is free of diacyl peroxide, and
- wherein the treatment composition is configured to deposit greater than about 189 micrograms of the antioxidant per gram of fabric.
A treatment composition comprising a plurality of first particles, each first particle comprising a solid matrix, an antioxidant disposed in the solid matrix, and a first particle surfactant disposed in the solid matrix,
- wherein the solid matrix comprises a water-soluble first carrier,
- wherein the antioxidant is present in an amount of from about 5% to about 50% by weight of each first particle,
- wherein the first particle surfactant is present in an amount of from about 10% to about 25%, by weight of each first particle,
- wherein the first particle is free of diacyl peroxide,
- wherein the treatment composition is configured to deposit greater than about 189 micrograms of the antioxidant per gram of fabric.
