摘要:
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. Furthermore, disclosed is a method for the recovery of a previously programmed, permanent shape of a hairdo, which has been temporarily brought into a temporary form or which has been deformed in a different manner.

Disclosed is a method for achieving a recallable hair deformation. A composition is applied onto hair, comprising at least one active agent, 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 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. Suitable active agents are for example macromers which may be cross-linked to provide shape memory polymers, wherein the permanent shape is fixed by means of the chemical cross-linking of the macromer, providing a shape memory polymer, which possesses at least one transition temperature Ttrans. Suitable active agents are also shape memory polymers, which have hard segments which may be cross-linked by physical interactions having a first transition temperature T′trans, which preferably is at least 10° C. above room temperature, and soft segments having a second transition temperature which preferably is at least 10° C. below T′trans. In addition to the permanent hairdo, a second (temporary) shape can be impressed. Furthermore, disclosed is a method for the recovery of a once programmed permanent hairdo, which has been brought into a temporary shape or which has been deformed in any other way.

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. Furthermore, disclosed is a method for the recovery of a once programmed permanent hairdo, which has been brought into a temporary shape or which has been deformed in any other way.

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. The macromer M possesses cross-linkable regions, as well as thermoplastic regions that are not cross-linkable and, after cross-linking, has a transition temperature of Ttrans. The polymer P has a hard segment with a first transition temperature T′trans, which is above room temperature, and a soft segment with a second transition temperature Ttrans which is lower than T′trans.

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. A method is also described for restoring a previously programmed permanent hairstyle that was temporarily transformed into a temporary shape or that was otherwise deformed.

摘要:
The object of the invention is a hair-treatment agent in the form of a two-phase gel, containing comminuted particles of a firm and shape-retaining gel based on a carrageenan-containing aqueous base in a fluid polyol matrix. The gel is a clear product with properties of a hair wax or hair cream and it can be dispensed, sprayed or foamed from a suitable container by means of a propellant.

A hair wax product is made by a process, in which a solid wax composition is heated to melt or soften it and then foamed with a gas in a mixer that applies shear energy to it. The gas is preferably air or a non-reactive gas, such as nitrogen. The gas is introduced to the liquified or softened solid wax composition in a sufficient amount so that the density of the resulting hair wax product is less than or equal to 0.9 g/ml, preferably 0.6 to 0.8 g/ml. The hair wax product contains bubbles and/or pores having a size of from 0.0001 to 5 mm and has melting and softening properties such that rubbing it by hand is sufficient to remove a waxy portion from it and work the waxy portion into hair.

The wax composition for styling human hair provides hold, strength and rigidity, includes at least one wax and/or waxy material, and has a density of less than or equal to 0.9 g/ml, after being foamed in a fluid or softened state with a gas, preferably air or a non-reactive gas, such as nitrogen, so that it includes a bubble and/or pore structure. In the method for styling human hair this wax composition is applied to the hair and the hair is shaped with the wax composition applied to it.
