Abstract
A multiple product system regimen for providing improved conditioning benefits to hair.
Claims11
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):
- wherein one of R71, R72, R73 and R74 of formula (XII) is selected from an aliphatic group of from 16 to 40 carbon atoms or an aromatic, alkoxy, polyoxyalkylene, alkylamido, hydroxyalkyl, aryl or alkylaryl group having up to about 40 carbon atoms;
- the remainder of R71, R72, R73 and R74 of formula (XII) are independently selected from an aliphatic group of from 1 to about 8 carbon atoms or an aromatic, alkoxy, polyoxyalkylene, alkylamido, hydroxyalkyl, aryl or alkylaryl group having up to about 8 carbon atoms;
- and X− of formula (XII) is a salt-forming anion selected from the group consisting of halides such as chloride and bromide, C1-C4 alkyl sulfate, and mixtures thereof;
- (b) a high melting point fatty compound;
- 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 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

- 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.
