A hair treatment composition comprising: a) a conditioning base comprising: i) a cationic conditioning surfactant having from 16 to 32 carbon atoms; ii) a fatty alcohol having from 8 to 22 carbon atoms; and b) from 0.1 to 10 wt % of a conditioning silicone; (c) from 0.1 to 5 wt % of a diesterquat selected from a diesterquat that comprises branched, saturated chains, a diesterquat that comprises unbranched, unsaturated chains, and mixtures thereof; wherein the ratio of b) to c) is from 1:1 to 1:0.1, provides improved deposition of silicone on hair surfaces.

Deposition system for hair

i) an alkali metal salt of an aldonic acid; ii) 0.1 to 5 wt %, citric acid by weight of the total composition; and iii) a surfactant; wherein the composition has a pH of from 3 to 5, provides repair to damaged internal protein of hair.

Hair treatment compositions

A hair treatment composition comprising: a) a conditioning base comprising: i) a cationic conditioning surfactant having from 16 to 32 carbon atoms; ii) a fatty alcohol having from 8 to 22 carbon atoms; and b) from 0.1 to 10 wt % of a microcapsule in which a core comprising benefit agent is encapsulated in a polymeric shell; and (c) from 0.1 to 5 wt % of a diesterquat, provides improved deposition of microcapsules and delivery of benefit agent to hair surfaces.

A hair treatment composition comprising: a) a conditioning base comprising: i) a cationic conditioning surfactant having from 16 to 32 carbon atoms; ii) a fatty alcohol having from 8 to 22 carbon atoms; and b) from 0.1 to 10 wt % of metal pyrithiones and mixtures thereof; wherein the composition further comprises: (c) from 0.1 to 5 wt % of a diesterquat; and wherein the ratio of b) to c) is from 1:1 to 1:0.1, provides improved deposition of metal pyrithione on hair surfaces.

A method of measuring a wet friction of a bundle of hair, using a system which includes a friction probe having a contact surface and fitted with a weight in the range of from 10 g to 500 g, inclusive, a means for securing the bundle of hair, and a water bath, the friction probe being connected to a texture analyser, the method including the step of i) providing a bundle of hair fibres. The method also includes the steps of ii) aligning the bundle of hair fibres; iii) securing the bundle of hair fibres; iv) immersing the bundle of hair fibres under water in the water bath; v) contacting the bundle of hair fibres with the contact surface of the friction probe, which is fitted with the weight; vi) moving the probe along the hair fibres; and vii) recording the friction generated under step vi).

Method for measuring wet friction of hair

Hair conditioning shampoo compositions are provided which contain a combination of conditioning agents including emulsified silicones, cationic polymers and certain fatty acid polyesters of polyols. Suitable fatty acid polyesters are sucrose pentalaurate, sucrose tetraoleate, sucrose pentaerucate, sucrose tetraerucate, sucrose tetrastearate, sucrose pentaoleate, sucrose octaoleate, sucrose pentatallowate, sucrose trirapeate, sucrose tetrarapeate, sucrose pentarapeate, sucrose tristearate and sucrose pentastearate, and mixtures thereof. The compositions give improved hair conditioning benefits, especially to hair which has been damaged, e.g. through environmental exposure or harsh mechanical or chemical treatments such as heat styling, perming or bleaching.

Shampoo compositions

Hair treatment compositions are provided which have conditioning benefits and which contain a fatty acid polyester of a polyol selected from cyclic polyols, sugar derivatives and mixtures thereof, in which at least 50% by weight of the total fatty acid moieties of the polyester are C20 or higher unsaturated fatty acid moieties. Specific examples of suitable fatty acid polyesters are sucrose trierucate, sucrose pentaerucate, sucrose tetraerucate, sucrose trirapeate, sucrose tetrarapeate, and sucrose pentarapeate, and mixtures thereof. The compositions are typically in the form of shampoos or conditioners and give surprisingly improved overall conditioning, in particular hair softness.
