HAIR TREATMENT COMPOSITION

Abstract

A hair treatment composition comprising: i) a cleansing phase comprising a surfactant, in which at least 50 wt % of the total surfactant comprises an ethoxylated alkyl sulphate anionic surfactant; ii) an oil-in-water emulsion comprising a silicone; iii) a piroctone compound at a level of 0.15 to 1.5 wt % of the composition; and iv) a cationic polymer in which the cationic polymer comprises a dimethyl diallyl ammonium moiety, at a level of 0.1 to 1.0 wt % of the composition; wherein the anti-dandruff agent component in the composition is less than 50 wt % in solid form.

6. The hair treatment composition according to claim 1 in which the piroctone compound antidandruff agent is piroctone olamine.

7. The hair treatment composition according to claim 1 wherein none of the anti-dandruff agent in the composition is in solid form.

8. The hair treatment composition according to claim 1 that is a shampoo.

9. The hair treatment composition according to claim 1 that comprises surfactant at a level from 3 to 45 wt % of the total composition.

10. A non-therapeutic method of treating hair or the scalp, comprising application of a hair treatment composition according to claim 1, to the hair or scalp.

11. The non-therapeutic method according to claim 10 in which the composition is washed off after use.

12. The hair treatment composition according to claim 9, comprising surfactant at a level from 5 to 25 wt % of the total composition.

[0090] 0.1 g of Example composition/g hair was applied evenly over a hair switch. Hair switches were washed twice. Once washed, switches were placed in drying cabinet (50° C.) until dry. Once dry, the switch was transferred to a jar containing 10 ml of ethanol. The jar was sealed and placed on a bottle roller for a fixed time. Using a syringe, an appropriately sized sample for analysis was removed from jar, and filtered through a syringe filter into a vial for analysis, using HPLC-UV methodologies, against a set of standards containing known amounts of Octopirox in ethanol (μg/ml).

[0091] The Examples of the invention deposit Octopirox onto the hair more effectively than the comparative Examples.

Example 2

[0092] A shampoo composition comprising (by weight of the composition) 13.0% sodium laureth sulphate, 1.5% cocamidopropyl betaine, 2.0% DC1788 silicone emulsion, 0.4% Carbopol 980, 0.75% perfume, 0.5% piroctone olamine, water to 100% and preservatives, citric acid and sodium hydroxide to specification, was tested for piroctone olamine deposition with a range of deposition polymers at the levels stated below. The amounts stated are for ppm deposition, with the standard deviation in brackets:

[0093] The deposition of piroctone olamine with Polyquaternium-6 as the deposition polymer is relatively high compared to other polymers, but also beneficially demonstrates a dose response.
