Abstract:
A solid, form-stable gel for hair treatment comprisingan aqueous or aqueous-alcoholic base; from 0.5 to less than 2 percent by weight of a carrageenan mixture containing kappa-carrageenans; and at least one additive selected from the group consisting of hair fixing polymers, amphiphilic associative thickeners, monoalcohols with 1 to 5 carbon atoms and polyalcohols with 2 to 5 carbon atoms; wherein said amphiphilic associative thickeners, when included in said at least one additive, are contained in an amount of from 0.2 to 10 percent by weight; said monoalcohols, when included in said at least one additive, are contained in an amount of at least 15 percent by weight; said polyalcohols, when included in said at least one additive, are contained in an amount of at least 15 percent by weight; and said hair fixing polymers, when included in said at least one additive, are contained in an amount of from 0.5 to 30 percent by weight; and wherein said carrageenan mixture containing kappa-carrageenan and said at least one additive are contained in the gel in respective amounts such that the gel is solid and form-stable and has a resistance of at least 0.15 N to a compressive force applied at 20Â° C. and 65% relative humidity by means of a cylindrical piston of a diameter of 8 mm 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.
