Hair care products

The invention relates to a hair care product based on a combination of at least one compound which is water-insoluble at room temperature but soluble in the medium and a water-soluble, halogen-free organic solvent.

Repeated bleaching, permanent waves or dyeing, but also due to climatic influences such as temperature differences or when irradiated with sunlight or by frequent washing of the hair with degreasing hair cleansing agents, causes damage to the hair structure. The hair becomes brittle and loses its shine. Furthermore, the hair becomes electrostatically charged when combing and the roughened hair surface causes matting and knotting of the hair. This makes it particularly difficult to comb and disentangle wet hair. Agents for the care of the hair with a combability-improving and nourishing effect which are applied to the wet hair have therefore become of considerable importance. Such agents are often distributed, for example, in the form of a hair conditioner, as so-called cream rinses, or as a hair treatment after shampooing in wet hair, left to act for a few minutes to an hour and then rinsed out with water.

Mainly cationic surfactants, in particular quaternary ammonium compounds, are used as hair-conditioning active ingredients for improving the hair structure. However, customary hair care products based on cationic surfactants only give satisfactory results when treating dry and porous hair. They are less suitable for the treatment of quickly regreasing hair, since their use increases the natural regreasing of the hair, which in turn deteriorates the durability of the hairstyle.

Accordingly, the object of the invention is to provide a hair care product based on more suitable hair-conditioning active ingredients, and to avoid the disadvantages described above.

For this purpose, it has now been found that a hair care product is characterized in that it is a combination of the components

(A) at least one water-soluble, halogen-free organic solvent and

(B) at least one water 0.05 to 2 weight percent at room temperature, but soluble in the agent compound selected from lkandiolen CSS to C20 ^_A, Cg to C20 ^-A l ^kantr i ^len ° and the mono- or monodiglycerides of saturated or unsaturated C12 to C20 ^{fatty acids} r

The hair care composition according to the invention can be in the form of a non-aerosol foam that can be sprayed with the aid of a suitable mechanically operated spraying device, or a spray cure.

Mechanical spraying devices are to be understood as devices which enable the spraying of a liquid without using a liquefied propellant. A suitable mechanical spray device can be, for example, a spray pump or an elastic container provided with a spray valve, into which the cosmetic agent according to the invention is filled under pressure, the elastic container expanding and from which the agent as a result of the contraction of the elastic container can be removed continuously when the spray valve is opened, used.

The agent according to the invention can also be filled into a pressure vessel with the addition of a propellant, the preparation being removed as foam and being easily metered and conveniently distributed over the hair by means of a valve provided with an application nozzle. Easily volatile chlorofluorocarbons, such as difluorodichloromethane or trichloromonofluoromethane, tetrafluorodichloroethane or lower alkanes, such as n-butane, i-butane and propane or also di- methyl ether and, furthermore, gaseous blowing agents present at the pressures under consideration, such as, for example, N2 N2O and CO2, and mixtures of the above-mentioned compounds. The blowing agents are advantageously contained in this agent in an amount of about 2 to 10 percent by weight.

Agents according to the invention which are rinsed out after use, such as hair treatments and rinses, are usually distributed in an amount of about 10 to 30 g in the towel-dried hair after shampooing, depending on the fullness of the hair. After an exposure time of 1 to 30 minutes, preferably 3 to 15 minutes, the hair is rinsed with water and then dried.

The exposure time of the agent according to the invention depends on the intended use of the agent within the given time limits. If it is a rinse, it is left on the hair for 1 to 5 minutes, while a duration of action of 3 to 15 minutes is customary for a hair treatment and the exposure time for a hair treatment with simultaneous tinting of the hair is 10 to 30 minutes is.

In the case of agents according to the invention which are not rinsed out again after use, such as spray cures, depending on the hair volume, 2 to 4 g of the agent are distributed in towel-dried hair. The hair is then dried.

The hair treated with the agent according to the invention has excellent wet and dry combability, a pleasant handle and an appealing gloss when dry.
