Abstract

A disposable substantially damp cleansing article is disclosed having a cleansing composition impregnated onto a flexible substrate such as a non-woven cloth. The impregnated compositions include lathering surfactants and water, and a water-binding agent resulting in a composition having a water activity less than 0.977 but no lower than 0.001. Amounts of water range from greater than 15% to no higher than about 40% by weight of the total article. Speed of lather formation and foam volume increases within the window of the stated water activity and water range.

Claims

1. A substantially damp cleansing product comprising:

(i) a water insoluble substrate; and

(ii) a cleansing composition impregnated onto the substrate comprising;

(a) from about 20 to about 60% by weight of total impregnated composition of lathering surfactants;

(b) from about 0.05 to about 5% by weight of total impregnated composition of a cationic conditioning agent salt;

(c) water; and

wherein the water is present at greater than 15% by weight of the product, but no higher than about 40%, and a water-binding agent present in an amount sufficient to result in a composition having a water activity less than 0.977 but no lower than 0.001.

2. The product according to claim 1 wherein the water-binding agent is a polyol or an inorganic salt.

3. The product according to claim 1 wherein the water-binding agent is glycerin.

4. The product according to claim 1 wherein the water insoluble substrate is a sheet selected from a group consisting of non-woven, woven, hydro-entangled and air entangled substrates.

5. The product according to claim 1 wherein the water is present from about 20% to about 35% by weight of the product.

6. A substantially damp cleansing product comprising:

(i) a water insoluble substrate; and

(ii) a cleansing composition impregnated onto the substrate comprising;

(a) from about 20 to about 60% by weight of total impregnated composition of lathering surfactants;

(b) from about 0.05 to about 5% by weight of total impregnated composition of a cationic conditioning agent salt;

(c) water; and

wherein the water is present at greater than 15% by weight of the product, but no higher than about 40%, and a water-binding agent present in an amount sufficient to result in a composition having a water activity less than about 0.94 but no lower than 0.001.

7. The product according to claim 6 wherein the water is present from about 20% to about 35% by weight of the product.

8. A substantially damp cleansing product comprising:

(i) a water insoluble substrate; and

(ii) a cleansing composition impregnated onto the substrate comprising;

(a) from about 20 to about 60% by weight of the composition of lathering surfactants;

(b) from about 0.05 to about 5% by weight of total impregnated composition of a cationic conditioning agent salt;

(c) water; and

wherein the water is present at greater than 15% by weight of the product, but no higher than about 40%, and a water-binding agent present in an amount from about 0.1 to about 60% sufficient to result in a composition having a water activity less than about 0.96 but no lower than 0.001.

9. The product according to claim 8 wherein the water is present from about 20% to about 35% by weight of the product.
