Abstract

The invention relates stable compact low viscosity hair care compositions comprising: from about 20 weight % to about 45 weight % total surfactant; from about 2 weight % to about 25 weight % branched anionic surfactant with a tail having an alkyl chain with 12 to 18 carbon atoms; from about 5% weight % to about 30 weight % linear anionic surfactant with a tail having an alkyl chain with 12 to 18 carbon atom; from about 0.1 weight % to about 8 weight % of a viscosity reducing agent; from about 40 weight % to about 80 weight % of water; wherein the concentrated shampoo has Ratio of Linear anionic surfactant to Branched anionic surfactant of about 0.3 to about 5, wherein the concentrated shampoo has a viscosity of less than 3000 cP at 26.5° C.

First claim

What is claimed is:

1. A stable shampoo composition comprising:
a) from about 20 weight % to about 45 weight % total detersive surfactant;
b) from about 2 weight % to about 25 weight % branched anionic surfactant with a tail having an alkyl chain with 12 to 18 carbon atoms; wherein the branched surfactant is sodium tridecyl sulfate;
c) from about 5 weight % to about 30 weight % linear anionic surfactant; wherein the linear anionic surfactant is sodium laureth sulfate with an average of one mole ethoxylate;
d) from 0.1 weight % to about 8 weight % of a viscosity reducing agent;
e) from about 40 weight % to about 80 weight % of water;
wherein the shampoo has Ratio of Linear anionic surfactant/Branched anionic surfactant of about 0.3 to about 5 wherein the shampoo has a viscosity of less than 3000 cps at 26.5° C.;
and wherein the composition further comprises from about 1 weight % to about 10 weight % of one or more foaming agent.

2. The shampoo of claim 1 is delivered in a foam form via an aerosol dispenser.

3. The shampoo of claim 1 , wherein the foaming agent is selected from the group containing hydrocarbon, halogenated hydrocarbon and mixtures thereof.

4. The shampoo of claim 3 , wherein the hydrocarbon foaming agent is selected from a group containing n-butane, isobutane, propane, cyclopropane and mixtures thereof.

5. The shampoo of claim 3 , wherein the halogenated hydrocarbon foaming agent is trans-1,3,3,3-tetrafluoropropene.

6. The shampoo of claim 1 , wherein the viscosity reducing agent is a water miscible solvent.

7. The shampoo of claim 1 , wherein the viscosity reducing agent is selected from the group containing dipropylene glycol, propylene glycol, glycerin, sodium xylene sulfonate and mixtures thereof.

8. The shampoo of claim 1 , wherein the composition further comprises from about 0.1 weight % to about 10 weight % amphoteric surfactant.

9. The shampoo of claim 1 , wherein the hair care composition further contains about 0.05 to 5 weight percent of a silicone conditioning agent.

10. The shampoo of claim 1 , wherein the composition further comprises from about 0.1 weight % to about 5 weight % of one or more anti-dandruff active.

11. The shampoo of claim 10 , wherein the anti-dandruff active is selected from the group containing piroctone olamine, climbazole, and salicylic acid and mixtures thereof.

12. The shampoo of claim 1 wherein the hair care composition further comprises from about 0.05 to about 2 weight % of the hair care composition of one or more cationic polymers.

13. The shampoo of claim 12 , wherein the cationic polymers are selected from the group consisting of guar hydroxylpropyltrimonium chloride, Polyquaternium-6, Polyquaternium-7, Polyquaternium-10, Polyquaternium-39, Polyquaternium-67, and mixtures thereof.

14. The shampoo of claim 13 , wherein the guar hydroxylpropyltrimonium chloride has a weight average molecular weight of from about 100,000 to about 2,000,000 g/m and a charge density of from about 0.2 to about 2.2 meg/g.

15. The shampoo of claim 1 , wherein the total surfactant level is from about 20% to about 45% by weight.

16. The shampoo of claim 1 , wherein the total surfactant level is from about 25% to about 35% by weight.

17. The shampoo of claim 1 , wherein the hair care composition further comprises about 0.5 to about 7 weight % of a perfume.
