Description

AEROSOL SPRAY FOR TREATING KERATINIC FIBERS

The invention relates to a preparation for the treatment of keratin fibers, in particular human hair in the form of an aerosol spray, and the use of this preparation for the treatment of keratin fibers, in particular human hair.

Keratin fibers, especially human hair, are undergoing a variety of treatments nowadays. The treatments that serve to permanently or temporarily shape the hair play an important role. Temporary shapes that are supposed to give a good hold without impairing the healthy appearance of the hair, such as, for example, its shine, can be achieved, for example, by hair sprays, hair waxes, blow dryer waves, etc.

Hair sprays usually contain synthetic polymers as a shaping component. Preparations which contain a dissolved or dispersed polymer can be applied to the hair by means of propellant gases or by a pump mechanism. As a rule, a satisfactorily uniform distribution of the polymer on the hair is achieved; application from spray or pump containers is easy and clean.

Hair waxes usually contain vegetable, animal or mineral waxes as a shaping component and are offered as solid formulations, usually in jars. For use, these products are first rubbed in the hand and then spread over the hair. These hair waxes, based on natural raw materials, ensure a good hold of the hair with a strong shine. Nevertheless, the hair waxes on the market can meet the needs of users simple application and easy distribution on the hair are not yet completely satisfactory. Rubbing on the hand requires either the use of gloves or a subsequent intensive cleaning of the hands to remove the greasy product residues. Furthermore, a very even distribution of the product on the hair is difficult to achieve and requires a lot of time.

Finally, so-called gloss sprays are also on the market. These can give human hair in particular a special shine due to their content of vegetable, mineral and / or synthetic oils. Since the conventional synthetic and natural film formers are practically insoluble in these oils, these gloss sprays have no styling properties. The possibility of incorporating film formers into gloss sprays using solvents, such as high amounts of ethanol, does not lead to satisfactory results, since the additional styling properties can only be achieved at the expense of a significantly poorer gloss and feel.

It has now surprisingly been found that the waxes used in hair waxes can also be formulated and used as aerosol sprays. This allows the product to be applied to the hair much more easily and evenly than the conventional solid formulations. Furthermore, even when the spray cans were completely emptied, there were no problems with the nozzle components being blocked by the wax components. The problem of "greasy hands" after application of the product is completely eliminated.

The present invention therefore relates to preparations for the treatment of keratin fibers, in particular human hair, for spraying as an aerosol spray, characterized in that they

At least one wax with a melting point in a range from 40 ° C to 90 ° C,

• at least one emulsifier and

• at least one blowing agent contain.

The first mandatory component of the preparations according to the invention is a wax with a melting point in a range from 40 to 90 ° C. In principle, all waxes can be used, which melt in the temperature range mentioned, which meet the general definition for waxes, as they exist for. B. is listed in UUmanns Encyklopadie der Technische Chemie, 4th edition, volume 24, page 3, left column, and which are physiologically compatible.

However, the waxes are preferably selected from vegetable, animal and mineral waxes, it being possible to use waxes which have a melting point in the range from 50 ° C. to 85 ° C., in particular from 60 ° C. to 75 ° C.

Particularly preferred waxes according to the invention are beeswax (Gera Alba), carnauba wax, candelilla wax, montan wax, microcrystalline waxes (microcrystalline paraffins) and cetyl palmitate.

The teaching according to the invention also includes the combined use of several waxes. An addition of small amounts of carnauba wax can be used to increase the melting and dropping point of another wax and to reduce its stickiness. Furthermore, a number of wax mixtures, possibly in a mixture with other additives, are also commercially available. The under the names "special wax 7686 OE" (a mixture of cetyl palmitate, beeswax, microcrystalline wax and polyethylene with a melting range of 73-75 ° C; manufacturer: Kahl & Co), Polywax ^® GP 200 (a mixture of stearyl alcohol and polyethylene glycol stearate with a melting point of 47-51 ° C; manufacturer: Croda) and "Weichceresin ^® FL 400" (a petroleum jelly / petroleum jelly / wax mixture with a melting point of 50-54 ° C; manufacturer: Parafluid Mineralölgesellschaft) are • Examples of mixtures preferably used according to the invention.

In a special embodiment of the invention, in addition to the compounds usually defined as waxes (see above), so-called “liquid waxes”, such as jojoba oil, can also be used, provided that the melting point of this “wax mixture” is not below 40 ° C.

Preferred anionic surface-active compounds are the salts of ether carboxylic acids and compounds containing phosphate groups, in particular the phosphoric acid mono-, di- and triesters of ethoxylated C10-C18, in particular C12-C14, fatty alcohols with degrees of ethoxylation of 2 to 10, in particular 3 to 5 , Non-ionic surface-active compounds contain z. B. a polyol group, a polyalkylene glycol ether group or a combination of polyol and polyglycol ether group. Such connections are, for example

Addition products of 2 to 30 moles of ethylene oxide and / or 0 to 5 moles of propylene oxide with linear fatty alcohols with 8 to 22 C atoms, with fatty acids with 12 to 22 C atoms and with alkylphenols with 8 to 15 C atoms in the alkyl group , C _j 2 C 22 "F ^ett säuremono- and diesters of addition products of 1 to 30 mol

May continue to the very readily biodegradable quaternary Esterverbindungen as they are for example sold under the trademark Dehyquart ^® series, and quaternized protein hydrolyzates, and silicone compounds are used according to the invention.

The compounds with alkyl groups used as surfactants can each be uniform substances. However, it is generally preferred to start from natural vegetable or animal raw materials in the production of these substances, so that substance mixtures with different alkyl chain lengths depending on the respective raw material are obtained.

In the case of the surfactants, which are addition products of ethylene and / or propylene oxide onto fatty alcohols or derivatives of these addition products, both products with a "normal" homolog distribution and those with a narrowed homolog distribution can be used. "Normal" homolog distribution is understood to mean mixtures of homologs that are used in the implementation of fatty alcohol and Alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alcoholates as catalysts. By contrast, narrow homolog distributions are obtained if, for example, hydrotalcites, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates are used as catalysts.

The third mandatory component of the preparations according to the invention is the blowing agent.

The blowing agent is advantageously selected so that it simultaneously serves as a solvent for the wax components. The blowing agent can then serve as a solvent for the wax components if they are at least 1% by weight, based on the blowing agent, soluble in it at 20 ° C.

Propellants preferred according to the invention are alkanes with 3 to 5 carbon atoms, such as propane, n-butane, isobutane, n-pentane and isopentane; n-butane and propane are particularly preferred.

According to a preferred embodiment, the preparations according to the invention contain the alkanes mentioned or mixtures of the alkanes mentioned as the only blowing agent. However, the invention also expressly includes the use of blowing agents of the chlorofluorocarbon type, but in particular the fluorocarbons. Dimethyl ether in amounts below 5%, based on the entire preparation, can also be present in the preparations according to the invention as an additional blowing agent. The blowing agents are preferably present in the preparations according to the invention in amounts of 40 to 98% by weight, based on the entire preparation. Amounts of 50 to 95% by weight, in particular 60-90% by weight, are particularly preferred.

The preparations according to the invention can consist solely of the three mandatory components mentioned. In particular, they contain the wax as the only styling component and are free of polymers, in particular polymers with a styling effect.

Furthermore, it has surprisingly been found that the oil components used in gloss sprays can also be incorporated into the preparations according to the invention. Thus, by applying preparations according to the invention in accordance with this embodiment, the hair can be given an improved shine. Furthermore, preparations according to this embodiment can achieve the object of imparting additional styling properties to the conventional gloss sprays. Both vegetable and mineral or synthetic oils can be used as the oil component.

A preferred embodiment of the present invention is therefore preparations which further contain at least one oil component selected from vegetable, mineral and synthetic oils. These oil components or oil components are preferably contained in the preparations according to this preferred embodiment in amounts of 0.5 to 50% by weight, in particular 5 to 50% by weight, based on the entire preparation.

According to the invention, (sweet) almond oil, avocado oil, soybean oil, sesame oil, sunflower oil, palm kernel oil, mango kernel oil, macadamia nut oil, apricot kernel oil, olive oil, wheat germ oil, pumpkin seed oil, mallow oil and hazelnut oil are particularly preferred.

Mineral oils, paraffin and isoparaffin oils and synthetic hydrocarbons are used in particular as mineral oils. An inventively employable synthetic hydrocarbon is for example the commercial products available as compound l, 3-di- (2-ethyl-hexyl) -cyclohexane (Cetiol ^® S). Mineral oils preferred according to the invention are paraffin oils.

Suitable synthetic oils are silicone compounds, in particular dialkyl and alkylarylsiloxanes, such as, for example, dimethylpolysiloxane and methylphenylpolysiloxane, and their hydroxyl-terminated, alkoxylated and quaternized analogs. Examples of such silicones are the products sold by Dow Corning under the names DC 190, DC 200 and DC 1401 and the commercial products DC 344 and DC 345 from Dow Corning, Q2-7224 (manufacturer: Dow Corning; a stabilized trimethylsilylamodimethicone), Dow Corning ^® 929 emulsion (containing a hydroxylamino-modified silicone, which is also referred to as amodimethicone), SM-2059 (manufacturer: General Electric) and SLM-55067 (manufacturer: Wacker). Preferred silicone compounds according to the invention are linear and cyclic, alkoxylated and non-alkoxylated dialkylsiloxanes, alkylarylsiloxanes and siloxanes with amino groups.

The oils which can be used according to the invention also include dialkyl ethers and dialkyl carbonates.

Dialkyl ethers which can be used according to the invention are, in particular, di-n-alkyl ethers with a total of between 12 to 36 carbon atoms, in particular 12 to 24 carbon atoms, such as, for example, di-n-octyl ether, di-n-decyl ether, di-n-nonyl ether, di- n-undecyl ether, di-n-dodecyl ether, n-hexyl-n-octyl ether, n-octyl-n-decyl ether, n-decyl-n-undecyl ether, n- Undecyl-n-dodecyl ether and n-hexyl-n-undecyl ether as well as di-tert-butyl ether, di-isopentyl ether, di-3-ethyldecyl ether, tert-butyl-n-octyl ether, isopentyl-n-octyl ether and 2-methyl-pentyl-n-octyl ether. The di-n-octyl ether is commercially available under the name Cetiol ^® OE.

The dialkyl carbonates which can be used according to the invention can be obtained by complete transesterification of low molecular weight dialkyl carbonates, for example dimethyl carbonate or diethyl carbonate, with, for example, fatty alcohols having 6 to 22 carbon atoms or their ethylene oxide and / or propylene oxide addition products. According to the invention particularly suitable for the symmetrical transesterification is di-n-octyl carbonate, which is obtainable by the transesterification of n-octanol (capryl alcohol), and is sold under the trade name Cetiol ^® CC. Further dialkyl carbonates which can be used according to the invention have branched alkyl groups. A commercially available product of this type is, for example, di- (2-hexyldecyl) carbonate, which is obtained by transesterification of diethyl carbonate with 2-hexyl-decanoI, a Guerbet alcohol, and is also referred to as “Guerbet carbonate”. Another preferred one Dialkyl carbonate with branched alkyl chains is di- (2-ethylhexyl) carbonate.

Although usually at room temperature, i.e. at 25 ° C, liquid oils are used, the invention also includes the use of mixtures of liquid and solid oil components, provided that these mixtures are liquid at room temperature.

In the preparations according to the invention of this preferred embodiment, the quantitative ratio of wax components and oil components is not subject to any fundamental restrictions. The proportion of wax components, based on the sum of the wax and oil components, is usually in the range from 0.5 to 99.5% by weight, in particular in the range from 10 to 90% by weight. Preparations in which this wax content is in the range from 40 to 75% by weight are distinguished by particularly outstanding properties. The proportion of propellant gas in the preparations according to this preferred embodiment is preferably 20 to 98% by weight, in particular 40 to 90% by weight and particularly preferably 50 to 80% by weight, based on the overall preparation.

Furthermore, it has been found that when silicone oils of the linear dialkylsiloxane type are used, the gloss on the hair is increased without the characteristics of the wax component changing to any appreciable extent. In contrast, when paraffin oils, silicone oils of the cyclic dialkylsiloxane type and vegetable oils were used, a softening effect with regard to the wax components was observed. The person skilled in the art can therefore use the oil component not only to increase the gloss effect, but also to influence the properties of the wax component in a targeted manner.

The preparations according to the invention generally contain further components which are customary for the corresponding products. Such other components are special
