  • Publication number: 20020098214
    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 forming a polysiloxane macroinitiator by grafting a radical initiator onto a polysiloxane via a nucleophilic displacement reaction between groups on the polysiloxane and radical initiator respectively, and reacting the polysiloxane macroinitiator so obtained with radically polymerisable monomers in an atom transfer radical polymerisation reaction to form a polysiloxane block copolymer. Also provided are cosmetic and personal care compositions, such as hair styling compositions, containing the polysiloxane block copolymers.

  • Publication number: 20020090348
    Abstract: Cosmetic or personal care compositions comprise from 0.01% to 10% by weight of a hair styling polymer comprising one or more hydrophobic groups, from 0.001% to 10% by weight of an optionally substituted cyclodextrin and a cosmetically acceptable diluent or carrier. The cyclodextrin complexes with the hydrophobic groups to increase the solubility of the hair styling polymer in the composition. The cyclodextrin thus allows the formulation of compositions with relatively higher water contents.

  • Patent number: 6365672
    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.

  • Patent number: 5656265
    Abstract: A hair styling and conditioning process comprising the steps of: contacting the hair with a compound having an electrophilic group and at least one hydrophobic group whereby the electrophilic group reacts with nucleophilic sites in and on the hair to give the hair a plurality of hydrophobic groups at the surface, in which the hydrophobic group is selected from the group consisting of C.sub.10-30 and C.sub.10-30 alkenyl groups. Preferably the electrophilic group is azlactone.Also a reversible hair styling process in which the hydrophobic group is selected from the group consisting of C.sub.1-30 alkyl, C.sub.2-30 alkenyl, phenyl, diphenyl, other aromatics, and fluoroalkanes, and the electrophilic group is selected from the group consisting of azlactone, sulphide from disulphide, sulphide from thiosulphonate, vinyl zulphone, vinyl sulphoximines, banzoxazinones and isocyanates.Novel azlactones, including pentadecyl and hexyl azlactone.

  • Patent number: 5464558
    Abstract: Carboxylic polymers useful in detergent compositions contain keto structural units incorporated into the polymer backbone. The units may be introduced by means of the compound 2,2'-diphenyl-4-methylene-1,3-dioxolane. The polymers show better biodegradability than the acrylic and acrylic/maleic polymers commonly used in detergent compositions, while the detergency building (calcium binding) is comparable or better.
