Abstract

Claims (39)

1. A detergent composition comprising:

a) from 30.0 to 40.0 wt % sorbent carrier comprising hydrophobic silica;

b) from 0.1 to 15% of an acid precursor comprising citrate;

c) a sorbed component comprising by weight of the detergent composition:

i) from 5 to 15% surfactant;

ii) from 5 to 15% phosphoric acid;

iii) from 2 to 10% gluconic acid;

iv) from 10 to 20% malic acid;

v) from 20 to 30% citric acid; and

vi) from 5 to 15% water;

wherein the sorbed component is sorbed by the sorbent carrier.

2. The detergent composition of claim 1 wherein the sorbent carrier comprises particles and wherein the particles are dispersed in a personal care product.

3. The detergent composition of claim 1 wherein the citrate is sodium dihydrogen citrate.

4. The detergent composition of claim 1 wherein the surfactant is caprylyl/capryl glucoside.

5. The detergent composition of claim 4 wherein the sorbed component is in aqueous form.

6. The detergent composition of claim 1 wherein the sorbed component has a pH of less than about 3.5.

7. The detergent composition of claim 1 wherein the sorbed component has a pH of less than about 2.

8. The detergent composition of claim 1 wherein the sorbent carrier comprises a mixture of hydrophobic silica particles comprising a first portion and a second portion, wherein the second portion is less hydrophobic than the first portion.

9. The detergent composition of claim 1 wherein the sorbent carrier comprises porous hydrophobic silica particles, wherein each silica particle has an inner portion and an outer coating, and wherein the inner portion is less hydrophobic than the outer coating.

10. The detergent composition of claim 1 wherein the sorbent carrier is configured to at least partially dissolve in an alkaline environment with a pH greater than about 9 and to release the sorbed component.

11. A detergent composition comprising:

a) an aqueous component comprising by weight of the detergent composition:

i) from 5 to 15% surfactant;

ii) from 5 to 15% phosphoric acid;

iii) from 32 to 70% alpha hydroxy acid; and

iv) from 5 to 25% water;

wherein the aqueous component has a pH less than about 1; and

b) from 30.0 to 40.0 wt % sorbent carrier comprising hydrophobic silica, wherein the aqueous component is sorbed by the sorbent carrier.

12. The detergent composition of claim 11 wherein the sorbent carrier comprises a mixture of hydrophobic silica particles comprising a first portion and a second portion, wherein the second portion is less hydrophobic than the first portion.

13. The detergent composition of claim 11 wherein the sorbent carrier comprises porous hydrophobic silica particles, wherein each silica particle has an inner portion and an outer coating, and wherein the inner portion is less hydrophobic than the outer coating.

14. The detergent composition of claim 11 wherein the sorbent carrier is configured to dissolve or partially dissolve in an alkaline environment with a pH greater than about 9 and to release the aqueous component.

15. The detergent composition of claim 11 wherein the sorbent carrier comprises particles and wherein the particles are dispersed in a personal care product.

16. A detergent composition dispersed in a personal care product and comprising:

a) an aqueous component comprising by weight of the detergent composition:

i) from 5 to 15% surfactant;

ii) from 37 to 75% acid;

iii) from 5 to 25% water; and

b) from 30.0 to 40.0 wt % sorbent carrier comprising hydrophobic silica particles, wherein each particle has an inner portion and an outer coating, wherein the inner portion is less hydrophobic than the outer coating, and wherein the aqueous component is sorbed by the inner portion of the sorbent carrier.

17. The detergent composition of claim 16 wherein each portion of the sorbent carrier is configured to dissolve in an alkaline environment with a pH greater than about 9 and to release the sorbed component.
