Abstract: A method produces polar-modified rubber and olefin thermoplastic waste by grafting during a grinding process, for treatment, usable as compatibility agents in various plastic blends and composites, without the disadvantages of known functionalized recycled plastics, particularly the mechanical characteristics that are insufficient for their use. The waste is simultaneously ground and graft-modified in a temperature range between 40° C. and 140° C., in one method step. Scrap parts of vulcanized elastomer or olefin thermoplastic are comminuted to a particle size diameter of approximately 4 and 8 mm. The waste should be sorted by type, if possible. The shredded material is mixed with at least one organic peroxide and an ?,?-ethylene compound possessing at least one unsaturated polar group. The mixture is simultaneously ground and grafted at a specified dwell time and temperature range to a particle size diameter <1 mm. Residual components and byproducts are removed via nitrogen flushing.

Abstract: An applicator consisting of a dispenser in the form of a comb or brush and an active-substance preparation containing at least one hair-softening or hair-setting component in a concentration of from 0.01 to 20% by weight, based on the total weight of the active-substance preparation, and having a viscosity at room temperature of from 0.9 to 12 mPa.s enables hair to be specifically aftertreated with minimal effort and without adversely affecting the hair or scalp.

Abstract: An improved device for continuous application of a hair dye to a person's hair, without wetting the scalp, incorporates a hair dye reservoir consisting of a first porous material within a housing and teeth made of a second porous material, inserted into the first porous material and in capillary connection with it. The teeth in the surface area of their free ends are free from open pores, and the main pore direction of both the second porous material of the teeth and the first porous material of the reservoir is essentially parallel in the same direction as the longitudinal direction of the teeth. The first porous material of the reservoir extends over several times the penetration depth of the teeth in the penetration direction, and the pore size in the teeth is smaller than in the remainder of the reservoir.

Abstract: A dispenser for multicomponent hair-cosmetic products, such as hair-dyeing preparations, includes in one embodiment a tubular element including absorbent material in separate storage compartments for each product component, respectively, and a plurality of tines of absorbent material partially inserted into the storage compartments for transferring the components by capillary action from the storage compartments into the tines, where the components are mixed and immediately thereafter available for transfer from the tines to hair to be dyed.

Abstract: An applicator for the continuous application of a hair dye to the head hair of human beings, comprises a reservoir for hair dye absorbed in a first absorbent material within a tubular element, and teeth of a second absorbent material inserted into the element in a manner not contacting the first absorbent material, whereby for the transfer of the hair dye from the first absorbent material to the teeth not in contact therewith, the reservoir is connected to a rotation mechanism.

Abstract: Quaternary ammonium compounds corresponding to the formula ##STR1## are produced by esterification of ether amines corresponding to the formula ##STR2## with a fatty acid of the formula R.sup.2 --COOH and quaternization of the product obtained with an alkyl halide or a dialkyl sulfate. They are suitable for use as conditioning and revitalizing agents in hair-cosmetic preparations.

Abstract: There is disclosed a dispenser for hair treating solution and the like in the form of a comb or brush having a hollow spine and teeth of absorbent material inserted therein in capillary-active communication with treatment solution in a reservoir in the spine, the flow of solution from the spine through the teeth to the hair being dependent solely on the quantity of solution applied to the hair through capillarly action. Spacers may also be provided to hold the teeth in spaced relation to the scalp.

Abstract: An applicator for hair treating liquids comprising a hair clip in which one or more such liquids are expressed through mutually opposed linings in the jaw face; the combination of the applicator with such hair treating liquids; and a method for using the combination.

Abstract: Hair-treatment preparations containing as additive at least one surface-active phosphonic acid corresponding to general formula I, II or III below ##STR1## in which R.sup.1 represents a C.sub.5 -C.sub.21 alkyl, R.sup.2 represents hydrogen or --PO.sub.3 H.sub.2, and R.sup.3 represents hydrogen, hydroxyl, or, if R.sup.2 is --PO.sub.3 H.sub.2, --NH.sub.2, and R.sup.4 represents hydrogen or a lower alkyl group containing from 1 to 4 carbon atoms, or a water-soluble salt thereof, improved the wet combability of hair and reduce its tendency to develop static charges. Octane-1-phosphonic acid, decane-1-phosphonic acid and dodecane-1-phosphonic acid or their salts are particularly effective. The phophonic acids are used in quantities of from 0.05 to 10% by weight, and preferably in quantities of from 0.1 to 2.0% by weight together with anionic tensides.

Abstract: Cationic polymer - containing compositions in dry, powder form and having enhanced water-solubility are obtained by mixing (1) from about 5% to about 99% by weight of a solid, finely divided water-soluble cationic polymer and (2) from about 1.0% to about 95% by weight of a solid, finely divided, water-soluble anionic surfactant. The compositions are useful in cosmetic preparations and as flocculating agents, sludge dewatering agents and paper auxiliaries.

Abstract: A hair care preparation containing a hair conditioning effective amount of a compound of the formula: ##STR1## wherein: R.sup.1 is a C.sub.12-16 -n-alkyl;R.sup.2 is a C.sub.1-4 -n-alkyl;is a C.sub.1-4 -hydroxyalkyl;R.sup.4 is a C.sub.1-4 -n-alkyl or a C.sub.2-4 -hydroxyalkyl;A is an inorganic or organic acid anion; andn is the valence of said anion.

Abstract: Phosphonic acid esters obtained by reacting organophosphonic acids corresponding to the general formula R--PO.sub.3 H.sub.2, in which R is preferably an alkyl group containing from 6 to 18 C-atoms, with from 1 to 10 moles and preferably with from 1 to 5 moles of ethylene oxide and/or propylene oxide. These esters are useful as additives to hair treatment preparations, preferably to shampoos based on anionic surfactants and, preferably, ampholytic or betaine surfactants for improving the wet combability of hair. They are added in amounts between 0.1 to 10% by weight to hair treatment preparations, and between 1 and 5% by weight to shampoos.

Abstract: In order to neutralize the electrostatic charging of the hair which occurs where a plastic comb is used, the comb is made up of at least one section which negatively charges the hair during combing and at least one section which positively charges the hair during combing.

Abstract: In an induction energy transfer device comprising a static power conversion circuit for producing an alternating magnetic field of ultrasonic frequency of the type wherein the static power conversion circuit includes a parallel resonant circuit which comprises a coil which also couples power across an air gap, an improvement in efficiency and power transfer is obtained by including at least two such parallel resonant circuits in the power conversion circuit, one of which resonant circuits is tuned to the third harmonic of said fundamental frequency.
