A process for making a hair colorant composition involving: (a) providing a phase inversion temperature emulsion or microemulsion containing: (i) an oil component; and (ii) an emusifier selected from the group consisting of an alkyl and/or alkenyl oligoglycoside, an anionic surfactant, an esterquat, a polyolpoly-12-hydroxystearate, a fatty alcohol, a fatty alcohol polyethylene glycol ether, and mixtures thereof; (b) providing a dye component; and (c) combining (a) and (b) at a temperature of from 15 to 25&deg; C.

Method for producing hair dye products

Skin-conditioning succinic acid derivatives

Hair treatment applicator

Continuous hair dye dispensing device

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.

Dispenser for multicomponent hair-cosmetic products

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.

Applicator for continuous application of hair dye

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.

Quaternary ammonium compounds

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.

Dispenser for hair cosmetics

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.

Hair clip applicator for liquids and method

New zwitterionic polymers are obtained as the copolymerization product of:

Zwitterionic polymers and their use in hair treatment preparations

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.

Hair-treatment preparation for improved wet combability

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.

Water-soluble polymer compositions

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;

Quaternary ammonium compound hair conditioners

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.

Method and composition for increasing wet hair combability

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.
