Abstract

A cleansing product containing: (a) a water insoluble substrate; and (b) a surfactant composition impregnated onto the substrate, the composition containing: (i) at least one lathering surfactant; and (ii) at least about 40% by weight, based on the weight of the composition, of water.

Claims (29)

1. A cleansing product comprising:

(a) a water-insoluble substrate; and

(b) a surfactant composition impregnated onto the substrate, the surfactant composition containing:

(i) from about 10% to about 30% by weight of at least one sugar surfactant selected from the group consisting of alkyl polyglycosides and, glucamides;

(ii) a co-surfactant comprising,

(a) about 5% to about 20% by weight of an amphoteric surfactant, and

(b) up to about 20% by weight of an anionic surfactant;

(iii) about 5% to about 40% by weight of a water soluble oil component; and

(iv) at least about 30% by weight of water, all weights based on the total weight of the surfactant composition.

2. The product of claim 1 wherein the sugar surfactant comprises an alkyl polyglycoside corresponding to formula I:

R 1 O(R 2 O) b (Z) a   I

wherein R 1 is a monovalent organic radical having from about 6 to about 30 carbon atoms; R 2 is divalent alkylene radical having from 2 to 4 carbon atoms; Z is a saccharide residue having 5 or 6 carbon atoms; b is a number having a value from 0 to about 12; a is a number having a value from 1 to about 6.

3. The product of claim 1 wherein the amphoteric surfactant is present in the composition in an amount of from about 5 to 15% by weight, based on the weight of the composition.

4. The product of claim 1 wherein the co-surfactant comprises an anionic surfactant.

5. The product of claim 1 wherein the composition has a viscosity of, at most, about 1,000 cps.

6. The product of claim 1 wherein the water-insoluble substrate is a disposable sheet made from a non-woven material.

7. The product of claim 2 wherein in formula I, R 1 is a monovalent organic radical having from about 8 to 16 carbon atoms, b is zero, and a is a number having a value of from about 1.4 to 1.6.

8. The product of claim 4 wherein the anionic surfactant is present in the composition in an amount of from about 5 to 15% by weight, based on the weight of the composition.

9. A cleansing product comprising:

(a) a water-insoluble substrate;

(b) a surfactant composition impregnated onto the substrate, the surfactant composition containing:

(i) from about 15 to about 20% by weight of an alkyl polyglycoside corresponding to formula I:

R 1 O(R 2 O) b (Z) a   I

 wherein R 1 is a monovalent organic radical having from about 8 to about 16 carbon atoms; R 2 is divalent alkylene radical having from 2 to 4 carbon atoms; Z is a saccharide residue having 5 or 6 carbon atoms; b is 0; a is a number having a value from about 1.4 to about 1.6;

(ii)

(a) from about 5 to about 10% by weight of an amphoteric surfactant;

(b) from about 5 to about 10% by weight of an anionic surfactant;

(iii) from about 15 to about 30% by weight of a water soluble oil component; and

(iv) from about 30 to about 50% by weight water, all weights being based on the total weight of the surfactant composition.
