Abstract

A multiple product system regimen for providing improved conditioning benefits to hair.

Claims

1. A multiple product system for keratinic material comprising:

(1) a hair cleaning composition, for applying from about 0.3 mL to about 0.67 mL per 10 g of hair of the hair cleaning composition, comprising a dermatologically acceptable carrier, and from about 3% to about 40% of at least one surfactant selected from the group consisting of a branched and non-branched versions of decyl and undecyl alkyl sulfates which are either ethoxylated or non-ethoxylated;

decyl alcohol modified lauryl sulfate;

paraffin sulfonates with chain lengths ranging from C₁₃ to C₁₇;

mixtures of linear and branched-chain alcohol sulfates with carbon chain lengths C₁₂ to C₁₇ which are ethoxylated or non-ethoxylated;

sodium salts of branched, methyl-2-hydroxy-decyl ether sulfates, hydroxyethyl-2-dodecyl ether sulfates, hydroxyethyl-2-decyl ether sulfates;

monoethoxylated lauryl alkyl sulfates; and

mixtures thereof; and

about 0.05 wt % to about 10 wt % of a silicone emulsion; and

(2) a hair conditioning composition, for applying from about 0.3 mL to about 0.67 mL per 10 g of hair of the hair conditioning composition, comprising;

(a) a cationic surfactant having the formula (XII);

2. The multiple product system for keratinic material of claim 1 wherein the at least one surfactant is selected from at least one undecyl sulfate compound selected from the group consisting of:

CH₃—

(CH₂)_z—

CHR₂—

CH₂—

O(CH₂ CHR₃O)_y—

SO₃M;

where R₂ represents H or a hydrocarbon radical comprising 1 to 4 carbon atoms such that the sum of the carbon atoms in z and R₂ is 8, R₃ is H or CH₃, y is 0 to 7, the average value of y is about 1 when y is not=0, and M is a mono-valent or di-valent, positively-charged cation.

3. The multiple product system for keratinic material of claim 1 wherein the high melting point fatty compound is selected from the group consisting of cetyl alcohol, stearyl alcohol and behenyl alcohol.

4. The multiple product system for keratinic material of claim 1 wherein the cationic surfactant is selected from the group consisting of behenyl trimethyl ammonium chloride, methyl sulfate or ethyl sulfate, and stearyl trimethyl ammonium chloride, methyl sulfate and ethyl sulfate.

5. The multiple product system for keratinic material of claim 1 wherein the hair cleaning composition further comprises an additional anionic surfactant.

6. The multiple product system of claim 1 wherein the hair cleaning compositions is substantially free of organic solvent and hydrotrope;

and the hair conditioning composition is substantially free of anionic surfactants and anionic polymers.

7. A multiple product system for keratinic material comprising:

(1) a hair cleaning composition, for applying from about 0.3 mL to about 0.67 mL per 10 g of hair of the hair cleaning composition, comprising a dermatologically acceptable carrier, and from about 3% to about 40% of at least one surfactant selected from the group consisting of;

CH₃—

(CH₂)_z—

CHR₂—

CH₂—

O(CH₂ CHR₃O)_y—

SO₃M;

where R₂ represents H or a hydrocarbon radical comprising 1 to 4 carbon atoms such that the sum of the carbon atoms in z and R₂ is 8, R₃ is H or CH₃, y is 0 to 7, the average value of y is about 1 when y is not=0, and M is a mono-valent or di-valent, positively-charged cation; and

about 0.05 wt % to about 10 wt % of a silicone emulsion; and

(2) a hair conditioning composition, for applying from about 0.3 mL to about 0.67 mL per 10 g of hair of the hair conditioning composition, comprising;

(a) a cationic surfactant selected from the group consisting of behenyl trimethyl ammonium chloride, methyl sulfate or ethyl sulfate, and stearyl trimethyl ammonium chloride, methyl sulfate and ethyl sulfate;

(b) a high melting point fatty compound selected from the group consisting of cetyl alcohol, stearyl alcohol and behenyl alcohol; and

(c) an aqueous carrier;

wherein the hair conditioning composition has a yield point of at least 5 Pa, and the yield point meeting the following mathematical expression;

Y≧

5.13X−

17.80

wherein Y is yield point of the composition, X is a total amount (percentage by weigh of the composition) of the cationic surfactant and the high melting point fatty compound;

and wherein the composition is substantially free of thickening polymers;

wherein upon application of the hair cleaning composition with or in series with the hair conditioning composition to keratinic material, more than about 350 ppm of silicone is deposited on the keratinic material; and

wherein the hair conditioning composition is substantially free of tertiary amines, tertiary amine salts, and di-long alkyl quaternized ammonium salts.

8. The multiple product system of claim 7 wherein the hair cleaning composition is substantially free of organic solvent and hydrotrope;

and the hair conditioning composition is substantially free of anionic surfactants and anionic polymers.

9. The multiple product system for keratinic material of claim 7 wherein the high melting point fatty compound is selected from the group consisting of cetyl alcohol, stearyl alcohol and behenyl alcohol.

10. The multiple product system for keratinic material of claim 7 wherein the cationic surfactant is selected from the group consisting of behenyl trimethyl ammonium chloride, methyl sulfate or ethyl sulfate, and stearyl trimethyl ammonium chloride, methyl sulfate and ethyl sulfate.

11. The multiple product system for keratinic material of claim 7 wherein the hair cleaning composition further comprises an additional anionic surfactant.
