Abstract: 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.

Abstract: The conditioning performance of small particle size emulsified silicone in a surfactant-based shampoo composition can be significantly boosted by the inclusion in the shampoo composition of an amino functionalised silicone. Accordingly, the invention provides an aqueous shampoo composition comprising, in addition to water: i) at least one surfactant chosen from anionic, nonionic, zwitterionic or amphoteric surfactants or mixtures thereof; ii) an amino functionalised silicone; and iii) emulsified particles of an insoluble, non-amino functionalised silicone, in which the average silicone particle size of the emulsified non-amino functional silicone in the shampoo composition is less than 2 microns.

Abstract: The invention relates to aqueous hair care compositions including conditioners, shampoos, and mousses. The invention also relates to methods of treating hair, and more particularly to treating hair with aqueous hair care compositions which contain one or more elastomeric resinous materials. These materials when tested at the same concentration that could be incorporated into a product exhibit a G′ modulus between 1×102 and 1×105 dynes/cm2. Furthermore these resins when mixed with a hydrophilic or hydrophobic diluent at a ratio of 1:95 to 95:1% and this mixture then incorporated into an aqueous emulsion in the range of 0.1 to 10% have been demonstrated to deliver a consumer perceptible increase in hair body without sacrificing conditioning attributes.

Abstract: The invention provides a hair treatment composition such as a shampoo or conditioner suitable for topical application to hair for the repair and prevention of damage, comprising (i) cholesterol, and (ii) a hair benefit agent which is a mixture of a basic amino acid and a fatty acid. Preferably the cholesterol and hair benefit agent are compounded into a dispersion of multilamellar vesicles, stabilised with nonionic surfactant.

The invention also relates to hair conditioning compositions. The invention also relates to a method for conditioning the hair, which comprises contacting said hair with a composition according to the invention.

Abstract: In the present invention, an actuating mechanism for a hand held canister is provided in which a slider is moveable by finger pressure from a valve-disengaged position into a valve-engagable position and a concealed spring returns the slider to a valve-disengaged position when finger pressure is removed. The spring is preferably molded with the slider, projects through a slit in the over-cap of the canister and acts in a vertical plane against a stop depending from the over-cap. It is energised when the slider is moved into the valve engagable position. The slider is preferably releasably locked in the valve disengaged position.

Abstract: The invention provides the use of a hair benefit agent as an ingredient in a topical hair treatment composition for the purpose of targeting an active endogenous hair fiber enzyme when the composition is applied to the hair, thereby delivering a hair benefit via the interaction of the hair benefit agent with the enzyme.

Abstract: An aqueous non-aerosol hair styling composition having 55% or less VOC content, said composition comprising (i) a water soluble or dispersable fixative polymer of about 10 to about 1000 Kilo Daltons and in an amount ranging from 1% to 40% by weight of the composition; (ii) a neutralizing agent in an amount ranging from 0.1 to 10% by weight and selected from the group consisting of 2-amino, 2-methyl, 1-propanol, dimethyl stearamine, sodium hydroxide, and potassium hydroxide; (iii) a surfactant in an amount ranging from 0.01% to 5% by weight and selected from the group consisting of sodium dioctyl sulfo succinate, sodium dodecyl sulfate, cocoamidopropyl betaine, and sodium laureth sulfate; (iv) a salt ranging from 0.01% to 10% by weight and selected from the group consisting of sodium benzoate, and magnesium acetate; (v) an alcohol ranging from 10% to 90% by weight; and (vi) water ranging from 10% to 90% by weight.

Abstract: A process for making a polysiloxane block copolymer which is built up from units of the formula [A] [B], in which A is a polymeric block built up from radically polymerisable monomer, and B is a polysiloxane block, the process comprising the steps of polymerising a radically polymerisable monomer in the presence of an atom transfer radical initiator to form an polymer which is end-functionalized with a leaving group capable of nucleophilic substitution by nucleophilic end-groups on a polysiloxane, and reacting the polymer with a polysiloxane having nucleophilic end-groups so that a polysiloxane block copolymer is formed via a nucleophilic displacement reaction between the end-groups on the polysiloxane and leaving groups on the polymer respectively. Also provided is a cosmetic and personal care composition, such as a hair styling composition, comprising the polysiloxane block copolymer as described above.
