Abstract

Opaque cleaning compositions substantially free of opacifying agents and pearlizers, and methods for the same are disclosed. The cleaning composition may include a synergistic combination of a surfactant system and one or more salts. The surfactant system may include a nonionic surfactant and two anionic surfactants, and the one or more salts may include a multivalent ion. In some examples, the cleaning composition is free of thickeners.

First claim

What is claimed is:

1. A cleaning composition, comprising:
a surfactant system comprising one or more surfactants; and
one or more salts;
wherein the one or more salts comprise calcium chloride and the one or more surfactants comprise sodium lauryl ether sulfate (SLES);
wherein the cleaning composition comprises, based on the total weight of the cleaning composition,
2 wt % SLES and 3 wt % calcium chloride,
3 wt % SLES and 2 wt % calcium chloride, or
3 wt % SLES and 3 wt % calcium chloride;
wherein the cleaning composition is opaque without an opacifying agent or pearlizing agent; and
wherein the cleaning composition has no phase separation and/or sedimentation.

2. The cleaning composition of claim 1 , wherein the cleaning composition is substantially free of thickeners.

3. The cleaning composition of claim 1 , wherein the one or more surfactants further comprise a linear alkylbenzene sulfonates (LAS).

4. The cleaning composition of claim 3 , wherein the cleaning composition comprises a ratio of LAS to SLES of from about 0.5:1 to about 1.5:1.

5. The cleaning composition of claim 1 , wherein the one or more surfactants comprise a nonionic surfactant and two anionic surfactants.

6. The cleaning composition of claim 5 , wherein the nonionic surfactant comprises alkoxylated fatty alcohol nonionic surfactants.

7. The cleaning composition of claim 5 , wherein the two anionic surfactants comprise LAS and SLES.

8. The cleaning composition of claim 5 , wherein the one or more surfactants consist of the nonionic surfactant and the two anionic surfactants.

9. The cleaning composition of claim 1 , wherein the surfactant system comprises LAS, SLES, and alkoxylated fatty alcohol present with a LAS:SLES:alkoxylated fatty alcohol ratio of about 2:2:1.

10. The cleaning composition of claim 9 , further comprising a fragrance, wherein the presence of the fragrance does not affect opacity, viscosity, and stability of the cleaning composition.

11. The cleaning composition of claim 5 , wherein the one or more surfactants comprise LAS, SLES, and alkoxylated fatty alcohol in a ratio of about 3:3:2 to about 2:2:1, respectively.

12. A method for preparing the cleaning composition of claim 1 , the method comprising contacting the surfactant system and the one or more salts with one another.
