Definitions

• the invention relates to an agent for setting the hair on an aqueous, alcoholic or aqueous-alcoholic basis, which contains 50 to 100 percent neutralized shellac in combination with hydroxypropylchitosan, hydroxybutylchitosan, hydroxypropylcellulose and / or hydroxybutylcellulose.
• the temporary reshaping of the hair is generally based on the use of hair-setting agents, the essential component of which are solutions of film-forming natural or synthetic polymers.
• synthetic polymers are anionic polymers such as acrylic acid or methacrylic acid homopolymers or copolymers, copolymers of acrylic acid and acrylamides and copolymers based on alkyl vinyl ethers and maleic acid monoalkyl esters, amphoteric polymers such as copolymers of octylacrylamide, acrylate and butylaminoethyl methacrylate and nonionic polymers such as vinylpyrrolidone homopolymers, vinylpyrrolidone-vinyl acetate copolymers and copolymers of vinylpyrrolidone, vinyl acetate and vinyl propionate.
• Synthetic hair-fixing polymers are preferred by radical polymerization of monomeric petro- chemical products, i.e. from non-renewable raw materials.
• synthetic polymers can contain contaminants from monomers, polymerization stoppers and polymerization regulators, which can be toxicologically unsafe.
• Natural polymers do not have the disadvantages of synthetic polymers described above.
• the most suitable natural hair-setting polymers are Schel varnish, polysaccharides or derivatives of polysaccharides, in particular cellulose derivatives, chitosan or chitosan derivatives.
• Hair fixatives the hair-setting effect of which is based on shellac as a film-forming agent, generally adhere strongly to the hair, making the hair difficult to style. In addition, such hair fixatives leave residues on the hair which are difficult to remove.
• Hair-setting agents containing polysaccharides are generally difficult to spray due to the thickening effect of polysaccharides. Furthermore, these agents have the disadvantage that when combing out the hair, dandruff formation and the formation of a gray coating on the hair can occur.
• Polymers suitable for use in hair setting agents must have a multitude of properties. For example, they have to Dissolve alcohols and alcohol-water mixtures well and be contracted with the commonly used aerosol propellants.
• a general problem with setting products is the durability of the hairstyles created with them. For example, washing the hair loses the setting effect of the products.
• the object was therefore to provide a means for setting the hair that does not have the disadvantages of the previously known means.
• the middle is said to make the hair easy to style, to give the hair shine and to ensure good hair strengthening beyond washing. Furthermore, with good sprayability and resistance to atmospheric humidity, it should dry quickly and act less stressfully on the hair.
• the present invention therefore relates to an agent for setting the hair on an aqueous, alcoholic or aqueous-alcoholic basis, which is characterized in that it
