Abstract: A method of setting hair or fur comprises applying to the hair or fur a composition for reducing keratin disulfide bonds, allowing the hair or fur to stand in a desired configuration, applying to the hair or fur a composition to set the hair or fur in a desired wave or straightened configuration, and washing or drying the hair or fur, where the composition to set the hair or fur is an ionic, water-soluble compound, which is substantially non-oxidizing to the products of keratin reduction and which reforms substantially all the keratin disulfide bonds, while substantially avoiding precipitation. The kit comprising and facilitating the same method is included.

Abstract: The invention relates to novel reducing compositions for reducing the disulfide bonds of keratin, comprising a regenerable reducing agent, such as an iodide salt, ferrocyanide salt, bromide salt and antimony(III) tartrate salt, capable of reducing the disulfide bonds of keratin, in combination with a consumable reducing agent, such as a salt or ester of thioglycolic acid, or a sulfite, bisulfite, hydrosulfite, metabisulfite or sulfoxylate salt, in which the consumable reducing agent is capable of regenerating the regenerable reducing agent by reducing the oxidized form of the regenerable reducing agent. Neutralizing compositions compatible with such reducing compositions, as well as methods for permanently waving or straightening hair or fur, are also encompassed by the invention.

Abstract: This disclosure is concerned with a novel limp, low-pressure-drop catalytic mat, particularly adapted for use in ignitible gas-flow systems, such as heated hair curlers and the like, comprising in preferred form a loosely packed quartz fiber mat to the fibers of which have been adhered oxide particles as of alumina and the like, coated with platinum catalytic particles, without, however, impairing the limpness, looseness and flexibility of the mat.

Abstract: This disclosure deals with removing rapidly chlorine retained by the skin and hair of, for example, swimmers, after exposure to chlorinated water by means of a stoichiometric excess of a suitable reducing agent, such as an alkali thiosulfate and the like in aqueous solution, and with toilet soaps and shampoos comprising said agent adapted to effect said removal.

Abstract: In the repeated production of a fuel cell component consisting of a uniform mixture of an electrocatalyst and a wetproofing agent, an aqueous colloidal fluorinated hydrocarbon resin dispersion is rapidly and reproducibly flocculated, preferably in less than 5 minutes, in the presence of an aqueous suspension of a novel platinum-on-carbon electrocatalyst by means of a polycationic salt solution, the salt concentration being preferably between 10.sup.-3 and 10.sup.-6 molar.
