Solid, form-stable gels for hair treatment

摘要

The solid, form-stable gel for hair treatment contains an aqueous or aqueous-alcoholic base; from 0.5 to less than 2 percent by weight of a carrageenan or a mixture of carrageenans; at least one carrageenan-amount-reducing additive selected from the group consisting of hair fixing polymers, amphiphilic associative thickeners, monovalent alcohols having 1 to 5 carbon atoms, polyvalent alcohols having 2 to 5 carbon atoms and water-soluble salts that release calcium and/or potassium ions in aqueous media. The carrageenan or mixture of carrageenans and the at least one additive are contained in the gel in respective amounts so that the gel is solid and form-stable to a compressive force of at least 0.15 N applied at 20° C. and 65% relative humidity by means of a cylindrical piston that is depressed at a rate of 0.5 mm/s until a compression depth of 1 mm is reached after which the piston is removed at a rate of 0.5 mm/s.
