  • Publication number: 20140148407
    Abstract: The invention provides an aqueous gel comprising: a) from 0.5 to 5 wt % dispersed modified cellulose biopolymer, wherein the modification consists of the cellulose having its C6 primary alcohols oxidised to carboxyl moieties (acid/COOH—) on 10 to 70% of the glucose units and substantially all the remainder of the C6 positions occupied by unmodified primary alcohols; b) a water-soluble or water-miscible organic non-solvent for the modified cellulose biopolymer; c) 0 to 10 wt % non-surfactant electrolyte, and d) water; in which the aqueous gel comprises less than 3 wt % oil phase ingredients. The aqueous gels of the invention offer excellent tactile properties, in particular superior skin feel and reduced stickiness. Furthermore, the gels have thixotropic properties, allowing their usage in pumpable or sprayable formats. They also provide sufficient structure for the suspension of a variety of particulate materials.

  • Patent number: 8450260
    Abstract: A structured aqueous detergent composition comprising modified cellulose and surfactant characterized in that the composition comprises: a) 0.2 to 10 wt %, preferably 0.4 to 7 wt %, anionic surfactant or zwitterionic surfactant or mixtures thereof, b) 0.5 to 5 wt %, preferably 1 to 2 wt %, dispersed modified cellulose biopolymer, wherein the modification consists of the cellulose having its C6 primary alcohols oxidized to carboxyl moieties (acid/COOH—) on 10 to 70% of the glucose units and substantially all the remainder of the C6 positions occupied by unmodified primary alcohols, c) 0 to 10 wt % non-surfactant electrolyte; d) 0 to 15 wt % other conventional detergent composition additives e) balance water. The invention also provides a method to manufacture the composition.

  • Patent number: 6338840
    Abstract: In a first aspect, a process for forming deodorant or antiperspirant sticks by continuously forming a mobile composition for dispensing into containers or molds at a rate matched with the rate at which it is dispensed, and in other aspects a process in which a mobile deodorant or antiperspirant composition is dispensed by injection molding, i.e. a process in which the deodorant or antiperspirant composition is dispensed under pressure. The composition at the time of injection moulding is preferably either in the vicinity of its regular set temperature, particularly in the range of about 0-3° C. below the regular set temperature and/or partially structured at the time of its delivery it into a container or mold.

  • Patent number: 6051734
    Abstract: A process for the optical resolution of racemic 3-(p-chlorophenyl)glutaramide (GAM) into its R isomer R--COOH and its S isomer S--COOH, which process includes the steps of either:(1) reacting racemic 3-(p-chlorophenyl)-glutaramide dissolved in a suitable solvent with S-(-)-.alpha.-methylbenzylamine of the formula H.sub.2 N--S'(2) precipitating out of the solution of step (1) R--CO.sub.2.sup.-.H.sub.3.sup.+ N--S';(3) dissolving the precipitate of step (2) in water, with the addition of a suitable acid; and(4) precipitating out of the solution of step (3) R--COOH; or(5) reacting racemic -3-(p-chlorophenyl)-glutaramide dissolved in a suitable solvent with R-(+)-.alpha.-methylbenzylamine of the formula H.sub.2 N--R';(6) precipitating out of the solution of step (5) S--CO.sub.2.sup.-.H.sub.3.sup.+ N--R';(7) dissolving the precipitate of step (6) in water, with the addition of a suitable acid, and(8) precipitating out of the solution of step (7) S--COOH.

  • Patent number: 5773222
    Abstract: A solid phase method of detection or assay of the presence or amount in a serum or plasma sample of a target antibody specific to a cell surface antigen. The sample is contacted with an immobilised preparation of cells bearing the antigen and antibody bound thereto is detected or assayed by means of an indicator comprising a binding partner for the antibody bound to labelled latex particles.
