Toiletry formulations including low molecular carrageenan extractives which are present in amounts effective to provide for substantivity to hair and skin keratin and provide for conditioning of hair and skin as a result of the water-binding capacity of such extractives.

Toiletry formulations comprising low molecular weight carrageenan

An electrophoretic support comprising a base plate having on at least one side thereof, a layer of an adherent resin containing ethylenically unsaturated groups capable of undergoing copolymerization with acrylamide. The support provides excellent adhesion for polyacrylamide gels and other electrophoretic media such as agarose.

Support for electrophoresis and method of producing same

A finely-divided solid blend of (1) purified agarose having an electroendosmosis value (-Mr) below 0.10 with (2) a water-soluble gum which by itself is soluble in boiling water without gelling, free from charged groups and from electroendosmosis, and soluble in water to form a solution of gum having at a concentration no greater than 10% by weight a viscosity of at least 10 cps. at 25.degree. C. The blend is soluble in water to form a gel having no electroendosmosis and useful as a medium for carrying out isoelectric focusing.
