    Abstract: Cationic polymers (I) are used in hair cosmetic formulations. (I) are obtained by: (1) free radical-initiated copolymerization of (a) 60-99 wt.% optionally substituted, optionally quaternized 1-vinylimidazole, (b) 1-40 wt.% acid or salt containing a polymerizable double bond and (c) 0-30 wt.% other comonomer and (2) quaternization if an unquaternized 1-vinylimidazole is used. An Independent claim is also included for shampoo formulations containing 0.01-5 wt.% (I).

    Abstract: Preparations in solid particle form containing active compounds, obtainable by intimate mixing of the active compound with a water-soluble melt of a) 10 to 90% by weight of a water-soluble polymer A of a viscosity Va of 1,000 to 120,000 cps and b) 10 to 90% by weight of a water-soluble polymer B of a viscosity Vb of 1 to 500 cps as a carrier substance, the viscosities Va and Vb being those of a 2% strength by weight aqueous solution at 20@C, measured by the capillary method ASTM D 2363-72 (European Pharmacopoeia, Vol. III, p. 37), and processing of the melt with shaping to give the particles.
