An aqueous, sulphate free shampoo composition for hair and scalp comprising:—a. a pre-formed emulsified silicone; b. a cationic deposition polymer; c. a hair substantive cationic conditioning polymer which is an APTAC polymer having a molecular weight of less than 1 million Daltons, preferably selected from a homopolymer of (3-acrylamidopropyl) trimethyl ammonium chloride and a (3-acrylamidopropyl) trimethyl ammonium chloride/acrylamide copolymer; d. a total amount of anionic surfactant, amphoteric surfactant and zwitterionic surfactant consisting of: (i) from 3 wt % to 13 wt %, by weight of the total composition at 100% activity, of an alpha olefin sulfonate anionic surfactant of general formula (I): R—CH═CH—CH—SO(I) in which Ris selected from linear or branched alkyl groups having from 11 to 13 carbon atoms and mixtures thereof; and M is a solubilizing cation; (ii) from 1 to 6%, by weight of an amphoteric or zwitterionic surfactant, selected from an alkyl betaine of general formula (II) R—N(CH)—CH—COOM(II) wherein R=C12 (Lauryl) or Coco derived; an alkyl hydroxy sultaine of general formula (III), R—N(CH)—CH—CH(OH)—CH—SOM(III) wherein R=C12 (Lauryl) or Coco derived; an alkyl aminopropyl hydroxy sultaine of general formula (IV), R—CO—NH—(CH)—N(CH)—CH—CH(OH)—CH—SOM(IV) wherein R=C12 (Lauryl) or Coco derived; an alkyl amphoacetate of general formula (V), R—CO—NH—(CH)—N(CH—CH—OH)(CH—COOM) (V) wherein R=C12 (Lauryl) or Coco derived; and mixtures thereof; and e. a suspending agent in which the weight ratio of (i) to (ii) ranges from 1:1 to 6:1 and the pH of the composition is from 3 to 6.5; and wherein the composition has a viscosity from 3,500 to 15,000 mPa·s, preferably from 4,000 to 12,000 mPa·s when measured using a Brookfield V2 viscometer using a spindle RTV5, for 1 minute at 20 rpm at 30° C. results in superior deposition and retention of silicone on hair.

Cleansing composition

Disclosed is a cosmetic composition comprising (i) 0.5 to 20 wt % of an organic sunscreen; and (ii) 2 to 60 wt % of a blend comprising a silicone elastomer gel of the Formula (I) and a non-silicone solvent selected from a hydrocarbon, an oil, a modified oil, an ester, an ether, an alcohol or a mixture thereof; wherein the composition comprises less than 1 wt % volatile silicone solvent. Formula (1)

Cosmetic compositions comprising silicone elastomer

An antimicrobial personal cleansing composition comprises: (i) an aqueous continuous phase including cleansing surfactant, (ii) a dispersed phase including dispersed particles of zinc-containing antimicrobial agents; and (iii) a solubilised oily liquid conditioning agent for skin and/or hair; which is light mineral oil having a kinematic viscosity of 3 to 5 cS (mm&#xb7;s) at 40&#xb0; C. and is solubilised in wormlike micelles in the aqueous continuous phase via the incorporation of an inorganic electrolyte and a linker molecule of formula R(X), wherein R is a C-Caryl ring or a C-Cmono-, di- or trivalent alkyl or hydroxyalkyl chain; n is 1 to 3 and each X is independently selected from &#x2014;OH, &#x2014;COOH and &#x2014;COOMgroups, where M is an alkali metal, ammonium or alkanolammonium cation; and in which the level of solubilised oily liquid conditioning agent is 0.45 to 3% by weight based on the total weight of the composition.

Antimicrobial personal cleansing compositions

The invention provides a personal cleansing composition comprising: (i) an aqueous continuous phase including cleansing surfactant; (ii) one or more oily liquid conditioning agents for skin and/or hair wherein the agent is solubilized in wormlike micelles in the aqueous continuous phase via the incorporation of at least one inorganic electrolyte and at least one linker molecule; (iii) one or more cationic deposition polymers which are selected from cationic polygalactomannans having a mean charge density at pH7 from 0.2 to 2 meq per 10 gram; and (iv) a hair substantive cationic conditioning polymer which is a homopolymer of (3-acrylamidopropyl) trimethyl ammonium chloride.

Personal cleansing compositions

The invention provides a personal cleansing composition having an aqueous continuous phase including cleansing surfactant and a solubilised hydrocarbon oil having a kinematic viscosity of 1 to 35 cSt at 40&#xb0; C. and a specific gravity of 0.76 to 0.87 at 25&#xb0; C.; in which the hydrocarbon oil is solubilised in wormlike micelles in the aqueous continuous phase by means of a linker molecule and an inorganic electrolyte; in which the linker molecule is selected from one or more compounds of formula: R(X), in which R is a Cto Cmono-, di- or trivalent saturated aliphatic or an aromatic hydrocarbyl group, n is 1 to 3 and each X is independently selected from &#x2014;OH and &#x2014;COOH; and in which the level of hydrocarbon oil in the composition ranges from 0.8 to 1.5% by weight based on the total weight of the composition.

Personal cleansing composition

Spray compositions and particularly anhydrous aerosol compositions containing particulate antiperspirant actives exhibit a tendency for nozzle blockage, impeding discharge of the contents when a polyol humectant, such as glycerol, is blended into its base composition. The problem is overcome or at least ameliorated by preparation of a base composition, suitable for employment in conjunction with a propellant, that contains a low molecular weight (liquid) polyethylene glycol (PEG) as humectant, and particularly a PEG of molecular weight 150 to 500.

Spray compositions

The design of the spray nozzle in an aerosol dispenser controls the characteristics of the spray that is produced. In a nozzle that comprises the elements of a multiplicity of inlet channels leading to a swirl chamber and an outlet orifice, the perception of wetness of a spray, such as an aqueous alcoholic deodorant spray, can be reduced by dimensioning the respective elements so that the sum of the widths of the inlet channels is less than the diameter of the swirl chamber and at least 1.5 times the diameter of the outlet orifice and the outlet orifice has a diameter of at least 0.3 mm together with the inlet channels being short, such as less than 0.5 mm. The new nozzle is especially suitable for spraying compositions having a low volatile organic carbon content and compositions comprising a significant proportion of water.
