Abstract: Hair and similar cosmetic preparations, i.e., aerosol hair sprays, hair conditioners, and hair setting lotions, etc. containing as the film-forming resin a quaternized copolymer of vinyl pyrrolidone and a copolymerizable vinyl monomer, i. e., a di-loweralkylaminoalkyl (or hydroxy alkyl) acrylate or methacrylate. Such compositions containing the quaternized copolymer exhibit excellent adhesion and holding power when employed for hair care preparations.
Abstract: A method for chemically fogging a silver halide photographic emulsion comprising reacting cyanoborohydride anion with the silver halide thereby forming metallic silver. The cyanoborohydride is preferably in the form of an alkali metal salt. Additionally, the emulsion may optionally include a gold salt.
Abstract: Crosslinked homopolymers and copolymers of N-vinyl-2-pyrrolidone formed by addition polymerization through ethylenically unsaturated groups are polymerized on solid, inert carriers. Heavy crosslinking is employed to render the polymers insoluble. The polymers can be made by copolymerizing, with N-vinyl-2-pyrrolidone, amides or substituted amides of unsaturated carboxylic acids, such as acrylamide, substituted and unsubstituted unsaturated carboxylic acids, such as methacrylic acid or halfacid maleates. Also included are comonomers containing basic nitrogen groups therein, such as vinyl pyridine, or alkylamino acrylates and methacrylates. The polymers are formed on inert substrates of both solid and porous types.
Abstract: Improved amphoteric surface active agents are obtained from tertiary amides that have been formed by condensation of esters of fatty acids with an aminoalkyl alkanolamine, e.g., aminoethyl ethanolamine, under special conditions, by conventional carboxymethylation with ClCH.sub.2 CO.sub.2 Na or ClCH.sub.2 CO.sub.2 H. The resultant amphoteric surface active agents are especially useful as wetting agents, forming agents, emulsifiers, etc., and in the manufacture of improved shampoos.
Abstract: A photographic element or film, such as photographic or medical X-ray film, having improved antistatic and slippage properties can be prepared by applying to said element or film a protective surface containing a calcium stearate dispersion and stearamido-propyl dimethyl-beta-hydroxy-ethyl ammonium nitrate.
