Description

The application relates to the technical field of temporary transformation keratinhaltiger fibers, especially human hair. The application relates to aerosol compositions containing at least one setting agent and at least one specific propellant, as well as the use of these compositions for the temporary transformation keratinhaltiger fibers and a corresponding method of application.

In principle, all animal hair, e.g. Wool, horsehair, angora hair, furs, feathers and products or textiles made from them. Preferably, however, the keratinic fibers are human hairs.

An attractive-looking hairstyle is now generally considered an indispensable part of a well-groomed appearance. Due to current fashion trends, hairstyles are always considered to be chic, which in many hair types can only be built up using firming agents or can be maintained for a longer period of time up to several days. Therefore, hair treatment agents that serve a permanent or temporary shaping of the hair play an important role. While the chemical structure of the keratin-containing fiber is modified by reduction and oxidation during permanent forming, such modifications of the chemical structure do not take place during the temporary forming. Corresponding temporary deformation agents usually contain synthetic polymers and / or waxes as the setting agent. Means for supporting the temporary shaping keratinhaltiger fibers can be formulated for example as a hair spray, hair wax, hair gel, hair foam. In particular, the application by means of aerosol dispensing container in the form of a spray or a foam enjoys high popularity.

The most important property of a temporary deformation agent for keratinous fibers, also referred to below as a styling agent, is that of treating the treated fibers in the newly modeled form - i. a form imprinted on the fibers - to give as strong a hold as possible. If the keratin fibers are human hair, it is also referred to as a strong hairstyle or the high degree of retention of the styling agent. The hairstyle hold is essentially determined by the type and amount of setting active ingredients used, but also an influence of the other components of the styling agent and the application form may be given.

In addition to a high degree of hold, styling agents must meet a whole range of other requirements. These may be broad in properties on the hair, properties of the particular formulation, e.g. Properties of the foam or sprayed aerosol, and properties that affect the handling of the styling agent, are subdivided, with the properties on the hair is of particular importance. Particularly noteworthy are moisture resistance, low tackiness and a balanced conditioning effect. Furthermore, a styling agent should be universally applicable for all hair types and mild to hair and skin.

To meet the different requirements, has been developed in the art as strengthening active ingredients a variety of synthetic polymers that are used in styling agents. The polymers can be subdivided into cationic, anionic, nonionic and amphoteric setting polymers. Ideally, when applied to hair, the polymers give a polymer film which, on the one hand, gives the hairstyle strong hold but, on the other hand, is sufficiently flexible not to break under stress. If the polymer film is too brittle, it leads to the formation of so-called film plaques, that is, residues that detach during the movement of the hair and give the impression that the user of the corresponding styling agent would have dandruff. Similar problems arise when waxes find use as a firming agent in the styling agent.

In particular, the application in the form of an aerosol requires additional measures. The aerosol product must spread well on the keratin fiber, i. for products in the form of an aerosol spray, the composition must be able to be applied uniformly as a fine spray evenly. If the composition is used in the form of an aerosol foam, then this foam must be voluminous and sufficiently stable that it can be applied to the fiber. At the same time, however, this foam must break easily on the fiber to ensure adequate wetting of the fibers with the composition.

The object of the present invention was therefore to provide a means for the temporary deformation of keratin-containing fibers, which is characterized by a high degree of hold and fits well on the Apply keratin fibers. The agent should be applied to the fiber in particular as a fine, targeted spray or as a fast-breaking foam.

To solve this problem, a specific propellant mixture based on fluorinated hydrocarbons is suitable. The use of fluorinated hydrocarbons as blowing agents for hair cosmetic agents is described for example in the international patent application WO2012 / 084529 described.

The aerosol compositions according to the invention comprise a cosmetic preparation a) and a blowing agent mixture b) and optionally further active ingredients and / or auxiliaries.

A first essential component of the aerosol compositions according to the invention is the firming agent contained in the cosmetic preparation. In the context of the temporary shaping of keratin-containing fibers, a firming active substance within the meaning of the invention contributes to the maintenance of the impressed shape of the fibers (in the case of hair, in particular, the hold of a hairstyle or of the hair volume). As a test method for the firming effect of a drug, the so-called curl retention test is often used.

Preferred aerosol compositions according to the invention comprise at least one setting cationic polymer. The setting cationic polymers have at least one structural unit containing at least one permanently cationized nitrogen atom. Permanently cationized nitrogen atoms are to be understood as meaning those nitrogen atoms which carry a positive charge and thereby form a quaternary ammonium compound.

They can be obtained by the relevant methods of preparative organic chemistry. The alkyl and alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose. The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides. The index number p in the general formula (T-II) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides and stands for a number between 1 and 10. While p in the individual molecule must always be integer and here before For all given values p = 1 to 6, the value p for a given alkyloligoglycoside is an analytically determined arithmetic quantity, which usually represents a fractional number.

In the case of the surfactants which are adducts of ethylene oxide and / or propylene oxide with fatty alcohols or derivatives of these addition products, both products with a "normal" homolog distribution and those with a narrow homolog distribution can be used. By "normal" homolog distribution are meant mixtures of homologs obtained in the reaction of fatty alcohol and alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alcoholates as catalysts. Narrowed homolog distributions, on the other hand, are obtained when, for example, hydrotalcites, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates are used as catalysts. The use of products with narrow homolog distribution may be preferred.

The preparations according to the invention very particularly preferably contain as surfactant at least one addition product of from 15 to 100 mol of ethylene oxide, in particular from 15 to 50 mol of ethylene oxide, to a linear or branched (in particular linear) fatty alcohol having from 8 to 22 carbon atoms.
