    摘要： The invention provides a method of conditioning hair by application of a conditioning shampoo composition, in which the hair is oxidatively-treated hair and in which the conditioning shampoo composition comprises: i) an aqueous continuous phase including cleansing surfactant, ii) a dispersed phase including emulsified droplets of non-volatile silicone having a mean droplet diameter (D3,2) of 1 micrometre or less, and iii) a solubilised oily liquid conditioning agent for skin and/or hair; in which the oily liquid conditioning agent is solubilised in wormlike micelles in the aqueous continuous phase via the incorporation of at least one inorganic electrolyte and at least one linker molecule which is selected from compounds of general formula R(X)n, in which R is an aryl ring having from 6 to 10 carbon atoms or a mono-, di- or trivalent alkyl or hydroxyalkyl chain having from 3 to 14 carbon atoms; n is 1 to 3 and each X is independently selected from —OH, —COOH and —COO-M+ groups, where M is an alkali metal, ammonium or alkanolammonium cation; and in which the level of solubilised oily liquid conditioning agent in the conditioning shampoo composition ranges from 0.45 to 3% by weight based on the total weight of the conditioning shampoo composition. The method according to the invention provides for the enhanced conditioning of oxidatively-treated hair compared to virgin hair.

    摘要： 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): R1—CH═CH—CH2—SO3−M+(I) in which R1 is 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) R2—N+(CH3)2—CH2—COO−M+(II) wherein R2=C12 (Lauryl) or Coco derived; an alkyl hydroxy sultaine of general formula (III), R3—N+(CH3)2—CH2—CH(OH)—CH2—SO3M+(III) wherein R3=C12 (Lauryl) or Coco derived; an alkyl aminopropyl hydroxy sultaine of general formula (IV), R4—CO—NH—(CH2)3—N+(CH3)2—CH2—CH(OH)—CH2—SO3−M+(IV) wherein R4=C12 (Lauryl) or Coco derived; an alkyl amphoacetate of general formula (V), R5—CO—NH—(CH2)2—N(CH2—CH2—OH)(CH2—COO−M+) (V) wherein R5=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.

    摘要： The invention provides an antimicrobial personal cleansing composition comprising: (i) an aqueous continuous phase including cleansing surfactant, (ii) a dispersed phase including dispersed particles of one or more zinc-containing antimicrobial agents; and (iii) a solubilised oily liquid conditioning agent for skin and/or hair; in which the oily liquid conditioning agent is light mineral oil having a kinematic viscosity of 3 to 5 cS (mm2·s−1) at 40° C. and is solubilised in wormlike micelles in the aqueous continuous phase via the incorporation of at least one inorganic electrolyte and at least one linker molecule which is selected from compounds of general formula R(X)n, in which R is an aryl ring having from 6 to 10 carbon atoms or a mono-, di- or trivalent alkyl or hydroxyalkyl chain having from 3 to 14 carbon atoms; n is 1 to 3 and each X is independently selected from —OH, —COOH and —COO−M+ groups, where M is an alkali metal, ammonium or alkanolammonium cation; and in which the level of solubilised oily liquid conditioning agent in the conditioning shampoo composition ranges from 0.45 to 3% by weight based on the total weight of the conditioning shampoo composition. The invention also provides the use of the composition described above for the enhanced deposition of one or more zinc-containing antimicrobial agents onto the skin and/or hair.
