Description

Pigmented spray gels

The invention relates to a sprayable gel for the treatment of hair, which contains at least one thixotropic thickener and optionally pigments, the use of a thixotropic thickener to stabilize insoluble pigments in sprayable gels, the use of the gel for shaping and / or luster of the hair and a corresponding method for shaping and / or luster of the hair.

Keratinic fibers, especially human hair, are now undergoing a variety of treatments. Treatments that serve permanent or temporary styling of the hair to create attractive-looking hairstyles play an important role. Due to current fashion trends hairstyles are always considered chic, which build up in many hair types only with the use of certain firming agents or can be maintained for a longer period of time, in contrast to a permanent deformation of the hair due to a chemical intervention in the hair structure with the help of a Permanent waving agents are used to achieve a temporary shaping hair treatment agent whose main components are film-forming polymers. As a temporary shapes, for example, designs such as curl, smoothing, Toupierung or consolidation in question. Temporary shapes that are supposed to give a good hold without affecting the healthy appearance of the hair, such as its gloss, for example, by styling agents, such as hair sprays, hair waxes, hair gels, hair fixatives, hair drier, styling sprays, etc. can be achieved. The temporary shaping is also referred to as hair styling or styling, shaping agents are also referred to as styling agents. In addition to the hair-fixing properties, these products are often also glossing effects. This is achieved by the addition of certain insoluble pigments, which produce light reflections on the hair.

From the prior art, as a possible application form of styling agents, higher-viscosity hair gels are known which have shaping properties, contain such pigments and also bring about the desired luster. These gels are taken from a tube or crucible, first rubbed by hand and then spread on the hair. Due to the high viscosity of these gels, the solid pigment particles remain distributed over longer periods in the gel and do not sediment.

Furthermore, lower viscosity hair gels are known from the prior art which can be mixed with a conventional mechanical spray device, e.g. spray a spray pump, or with a propellant from a conventional aerosol pressure vessel with a conventional spray head as a finely divided gel. The sprayable gels are much easier to dose and distribute in the hair than the high-viscosity gels. The sprayable hair gels known from the prior art have good hair-firming properties. Furthermore, sprayable hair gels containing solid pigments are also known from the prior art. A disadvantage of the sprayable hair gels known from the prior art, however, is that added glossy solid pigments sediment sometimes in part, and sometimes after longer periods of time in the spray bottles, so that these products are not optically satisfactory.

Since the appearance of a transparent viscous gel in a transparent container is an aesthetic pleasure and of particular charm, there is a strong interest in a hair gel, which has the known advantages of Sprühbarkeit, but at the same time overcomes the disadvantages mentioned.

It was therefore an object of the present invention to provide a sprayable hair gel in which solid pigments do not sediment even after long storage. This object is achieved by providing a sprayable gel for treating hair containing at least one thixotropic thickening agent.

A first subject of the present invention is therefore a sprayable hair treatment gel containing at least one thixotropic thickener. The dependent claims represent preferred embodiments of this subject invention.

Another object is the use of this gel for the temporary shaping / glossing of the hair.

Another object of the present invention is the use of thixotropic thickening agents to stabilize insoluble pigments in sprayable gels.

Finally, another object of the invention is a method for temporary hair shaping / glossing.

Thixotropic behavior is understood to mean the phenomenon that gels, when exposed to mechanical forces, e.g. by stirring or shaking, liquefy, but after completion of the mechanical stress solidify again.

In the context of the investigations on which the present invention is based, it has surprisingly been found that hair treatment gels containing at least one thixotropic thickener are very readily sprayable and solid pigment particles remain stable over longer periods of more than 6 months without sedimentation.

The gel of the invention can be sprayed with a conventional mechanical spray device, such as a spray pump, or with a propellant from a conventional aerosol pressure vessel with a conventional spray head as a finely divided gel. By its sprayability, the gel of the invention can be dosed more accurately and distributed to the hair evenly than conventional gels that hold solid pigments stable in solution and are offered in tubes or crucibles because of their high viscosity. In addition, contamination of the hands by the gel can be avoided by the gels according to the invention.

Furthermore, the gel of the invention holds stable pigment particles stable for longer periods of more than 6 months in solution and is therefore visually very appealing even after long storage times in contrast to commercially available pigmented spray gels, where already after a few weeks of storage significantly sedimentation phenomena are observed.

According to the invention come as a thixotropic thickener pseudo cationic polymers in question. Preferred pseudo cationic polymers are thixotropic copolymers of an acrylate component, an aminoacrylate component and a compound of the formula I,

wherein R ¹ and R ^{2 are} independently a Ci-C ₃₀ alkyl group or a group - [(CH ₂ CH ₂ O) XR ³ ], wherein R ^{3 is} hydrogen or a Ci-C ₃₀ alkyl group and X is stands for an integer of 1-30. Particularly preferred is the pseudo cationic copolymer of an acrylate, an amino acrylate and Cio-C ₃ o-alkyl-PEG-20-itaconate according to formula I, wherein the acrylate component of acrylic acid, C ₁ -C ₆ -alkylacrylic acid esters and C ₁ -C ₆ -alkyl methacrylates and
