Abstract: A process of dyeing hair by preparing and applying to the hair an aqueous reaction medium comprising an aminoethanethiol, a dihydroxybenzene and a ferricyanide or persulfate oxidizing agent, the composition optionally containing a color modifier selected from the group consisting of direct dyes, primary intermediates, couplers and mixtures thereof, and also containing a buffer to maintain the pH in the range from 2 to 11 during the oxidation reaction, and removing the aqueous reaction medium from the hair after the desired color is attained, and compositions and kits for practicing such processes.
Abstract: The present invention relates to compositions for inhibiting dye transfer between fabrics during washing. The compositions are specifically selected metallo catalysts; namely, porphyrins and phthalocyanines. Detergent compositions containing such porphyrins and/or phthalocyanines are also disclosed.
Abstract: There is provided a cationic organic peroxyacid having the general formula ##STR1## wherein: R.sub.1 is an optionally substituted, linear or branched, C.sub.8 -C.sub.12 alkyl or alkenyl group; R.sub.2 and R.sub.3 are each a methyl group; R.sub.4 is an optionally substituted, linear or branched C.sub.3 -C.sub.5 alkyl or alkenyl group; p is 0 or 1; z is an integer selected from 0-3; y is an integer selected from 0-5; w is 0 or 1; and X.sup.- is a counter anion. This peroxyacid was found to have good bleaching performance without showing incompatibility with anionic surfactants.

Abstract: The present invention relates to a process for printing characters or image with high durability on a fibrous sheet by a dry method, fabrics prepared by said printing process, and an apparatus for preparing said fabrics. The present invention relates to a process for preparing an information-bearing fibrous sheet, comprising the steps of temporarily forming an image such as characters or identification mark on a fibrous sheet by a dye; heating it to let the dye migrate into the fibrous sheet; and pressing another sheet material to the fibrous sheet with the image temporarily formed, with heat treatment for removing the excessive dye. The process of the present invention does not include the step of washing by water and allows dyeing with a sense of OA apparatuses. Therefore, it can be widely applied for clothing, and industrial and fashion fabric goods, etc. and expected to tempt the development of quite new applications.
Abstract: The invention relates to a composition, in particular a cosmetic composition, and more particularly one for dyeing keratin fibers, this composition containing at least one substance P antagonist in order to reduce or even eliminate the irritant effects of the dyes and/or pigments and/or dye precursors used during this dyeing. The substance P antagonist may form part of the dye composition itself or may be contained in a composition which is applied prior to the application of the dye composition.

The pH of the concentrates exceeds 12.5.
Abstract: A hydroxypropylated 2-nitro-p-phenylenediamine of formula (I), wherein R1 is a C1-4 alkyl, .beta.-hydroxyethyl, .beta.-hydroxypropyl or .gamma.-hydroxypropyl radical; R2 and R3 independently represent a .beta.-hydroxyethyl, .beta.-hydroxypropyl, .gamma.-hydroxypropyl or .beta.,.gamma.-dihydroxypropyl radical, with the proviso that at least one of R1, R2 and R3 is a .gamma.-hydroxypropyl radical, while the other two are not both a .beta.-hydroxyethyl radical; and cosmetically acceptable salts thereof. This compound may be used for directly dyeing hair to give blue through purplish blue shades which are wash-fast, light-fast, waterproof and sweat resistant.

Abstract: Stable granular detergent compositions with good flow and dispensing properties are prepared using percarbonate bleach and selected sulfate salts. Thus, particles comprising builders and surfactants are prepared separately from percarbonate bleach particles of defined particle size. Water-soluble sulfate particles having a defined size range and no more than 40 ppm iron and no more than 5 ppm copper are used in the compositions. The specified moisture content of the ingredients and overall compositions improves stability and flow/dispensing properties.

Abstract: Granular laundry detergents are formulated with percarbonate bleach and oxidation-sensitive ingredients such as brighteners, enzymes, perfumes and the like. The storage stability of such compositions is improved by the presence of silicate. For example, the tendency of stilbene-type brighteners to form undesirable yellow shades in the presence of percarbonate is diminished by the corporation of silicate materials into the granules.
