DESCRIPTION:
BRIEF SUMMARY
This application is a continuation under 35 U.S.C. 371 of PCT/EP94/01422, filed May 4, 1994.
BACKGROUND OF THE INVENTION
The subject of the present invention is an aqueous composition for fixing hair in the form of a highly viscous sprayable gel which contains a combination of at least one disaccharide or a disaccharide and an oligosaccharide with a cationic polymer and a thickener and has no monovalent aliphatic alcohols with 1 to 4 carbon atoms and determined salts.
At present, along with the conditioning and cleaning of hair, increasing importance is placed on shaping or hairstyling. In this respect, a distinction must be drawn between permanent and temporary hair-shaping.
Permanent shaping involves chemical action in the structure of the hair with the use of permanent wave compositions, whereas in temporary shaping, compositions whose essential constituents are film-forming polymers are used for fixing hair.
Film-forming polymers are conventionally used in alcoholic or aqueous-alcoholic solution in hair fixing compositions, foam fixing compositions, hair sprays and fixing gels.
The greatest disadvantages of known gel formulations are the poor proportioning and distributing properties of these gels, which are normally dispensed from tubes, and the intensive loading of hair associated with these gels.
This poses the problem of finding a hair fixing composition in gel form which provides good fixing of the hair and is easy to proportion and distribute in the hair.
SUMMARY OF THE INVENTION
Surprisingly, it has now been found that this problem is solved in an outstanding manner by an aqueous composition for fixing hair in the form of a highly viscous sprayable gel which contains a combination of a disaccharide or a mixture of a disaccharide and an oligosaccharide with a cationic polymer and a thickener and is free of monovalent aliphatic alcohols with 1 to 4 carbon atoms and certain inorganic salts.
Therefore, the subject of the present invention is an aqueous hair fixing composition in the form of a highly viscous sprayable gel containing 2 to 37 percent by weight of at least one disaccharide and 63 to 98 percent by weight of at least one oligosaccharide, contains trivalent metals.
The highly viscous sprayable gel according to the invention preferably has a viscosity of 200 to 10,000 m Pa.s (milli-pascal seconds), in particular preferably 500 to 6,000 m Pa.s. The viscosity of the gel according to the invention was measured by a Haake viscosimeter VT 501 at 25.degree. C. and a SV-DIN shear rate of 12.9 s.sup.-1 (row B, position 5).
Although it takes the form of a high-viscosity gel, the composition according to the invention can be sprayed with a conventional mechanical spraying device (e.g., a spray pump) or with a propellant from a conventional aerosol pressurized container with a conventional spray head as a finely distributed gel.
Since it may be sprayed, the composition according to the invention can be proportioned precisely and distributed uniformly in hair. The polymer film produced on the hair by the composition according to the invention is resilient and resistant to moisture in the air.
The composition according to the invention has a very good fixing action and may be washed out of hair easily. Surprisingly, in spite of the saccharide content in the composition according to the invention, hair which has been treated with the composition according to the invention does not have a sticky feel. Moreover, the composition according to the invention has none of the monovalent aliphatic alcohols with 1 to 4 carbon atoms which are contained in conventional compositions for fixing hair.
Saccharide-containing hair treatment compositions are known, for example, from DE-OS 34 04 627. The described compositions preferably take the form of lotions and necessarily contain salts. DE-OS 34 04 627 does not suggest providing a hair fixing composition in the form of a highly viscous sprayable gel which can be favorably proportioned and distributed easily and uniformly.
In the present invention, oligosaccharid
