Abstract: 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.

Abstract: The packaging system has two storage chambers for separately storing two components and a static micromixer for mixing them to prepare a formulation. The static micromixer is provided with plural disks (1) arranged in a stack. Each disk (1) has at least one inlet opening (2) for a feed stream, which is connected via a linking channel (3) with at least one outlet opening (4) for outflow of the feed stream into a mixing zone (5). The linking channel (3) is divided into two or more part channels (7) by microstructure units (6). Each part channel has a respective width that is smaller than a width of the mixing zone (5). A method of in-situ preparation of a formulation by mixing the components in the packaging system is also described.

Abstract: 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.

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.

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.

Abstract: The permanent shaping composition for permanent shaping of hair includes from 2 to 25 percent by weight of a conventional keratin-reducing compound and from 0.02 to 5 percent by weight of certain diquaternary polysiloxanes. The permanent wave-pretreatment composition includes from 0.02 to 5 percent by weight of the diquaternary polysiloxanes. The permanent shaping composition advantageously includes mercaptocarbonic acid reducing agents and has a pH of from 6 to 10 and may include conventional cosmetic additives. Methods for using the permanent shaping composition and the permanent wave-pretreatment composition are described which provide a more uniform permanant wave from the hair roots to the hair tips.
