  • Publication number: 20080311050
    Abstract: A method for achieving a retrievable hair restyling is described. Here a composition is applied to the hair, said composition containing at least one first active ingredient or active ingredient complex which can provide a shape memory effect by itself or in combination with other substances after being applied to the hair and after the performance of the treatment of the hair according to the invention. The composition additionally contains at least one second active ingredient, namely a hydrophobic substance with a water solubility of ?5 percent by weight at 20° C. The hair is arranged into a given (permanent) shape and said permanent shape is then fixed by inducing a chemical or physical modification of the applied active ingredients, wherein after a wanted or unwanted deformation of the shape memory, the original shape memory can be restored by means of a physical stimulation. In addition to the permanent hairstyle, a second (temporary) shape can be impressed.

  • Publication number: 20080305545
    Abstract: Methods and compositions are described herein for reconstruction of different functional tissues. Dissociated cells, differentiated cells, adult mesenchymal stem cells or embryonic stem cells are seeded on a scaffold. The scaffold will consist of a biocompatible, biodegradable shape memory (“SM”) polymers. In addition bioactive substances may be incorporated in the scaffold. Thermoplastic as well as thermoset materials with SM-effect can be used. The shape memory effect will be applied as an interactive link between the cells and the used polymeric scaffold. The degradation kinetics as well as shape memory transition temperature will be tailored by adjusting to monomer ratios of the co-oligomers. The shape memory effect will be used to create a degradation or release of bioactive substances on demand, induce forces on seeded cells or induce proliferation and differentiation of cells.

  • Publication number: 20070275020
    Abstract: A method for producing a retrievable hairstyling using shape memory polymers is described. Here a composition is applied to the hair, said composition containing a shape memory polymer P or a macromer M that can be cross-linked to a shape memory polymer, the hair is arranged into a given (permanent) shape and said permanent shape is then fixed by means of chemical cross-linking of the macromer M under the formation of a shape memory polymer and/or under physical cross-linking of the polymer P. The polymer P and the macromer M are formed from block copolymers, each of which comprises at least a first block and at least two additional blocks. The first block is a polyol and is selected from polyethers, dimerdiol and derivatives derived therefrom, as well as from polyesters of dicarboxylic acids with diols. The additional blocks are polyesters of hydroxycarboxylic acids or their lactones.

  • Publication number: 20060088494
    Abstract: A method for the provision of a recallable hair transformation using shape-memory polymers is disclosed. In this respect a composition which comprises a macromer or prepolymer which is cross-linkable to a shape-memory polymer is applied onto the hair and the hair is brought into a defined (permanent) shape and subsequently the permanent shape is fixed by means of the chemical cross-linking of the macromer or prepolymer under formation of the shape-memory polymer. The macromer or prepolymer contains segments which are cross-linkable by means of chemical bonds as well as thermoplastic segments which are not chemically cross-linkable. The shape-memory polymers do possess at least one transition temperature TTrans. In addition to the permanent shape of a hairdo a second (temporary) shape can be impressed.

  • Publication number: 20050244353
    Abstract: Disclosed is a method for achieving a recallable hair deformation. A composition is applied onto hair, comprising at least one first active principle or active complex, which, alone or in combination with further compounds, is able, after application to the hair and after carrying out the treatment of hair in accordance with the present invention, to provide a shape memory effect. The composition comprises at least one second active principle, which is a cationic agent. The hair is brought into a defined (permanent) shape and the permanent shape is subsequently fixed by means of inducing a chemical or physical change of the applied agents, wherein after a desired or undesired deformation, the memory shape of the initial memory shape may be recovered by means of a physical stimulation. In addition to the permanent hairdo, a second (temporary) shape can be impressed.

  • Patent number: 6720402
    Abstract: Shape memory polymer compositions, articles of manufacture thereof, and methods of preparation and use thereof are described. The shape memory polymer compositions can hold more than one shape in memory. Suitable compositions include at least one hard segment and at least one soft segment. At least one of the hard or soft segments can contain a crosslinkable group, and the segments can be linked by formation of an interpenetrating network or a semi-interpenetrating network, or by physical interactions of the blocks. Objects can be formed into a given shape at a temperature above the Ttrans of the hard segment, and cooled to a temperature below to Ttrans of the soft segment. If the object is subsequently formed into a second shape, the object can return to its original shape by heating the object above the Ttrans of the soft segment and below the Ttrans of the hard segment.
