Abstract: The disclosure relates to a method for decolorization of a dye-colored synthetic polymer, which includes the steps of treating a dye-colored synthetic polymer, such as polyester, with a treatment composition at pH 4 or less, the treatment composition comprising hydrogen peroxide, an iron catalyst, water, and a ketone. The resulting decolorized synthetic polymer is then separated from the treatment composition.

Abstract: The disclosure relates to a method for decolorization of a dye-colored synthetic polymer, which includes the steps of treating a dye-colored synthetic polymer, such as polyester, with a treatment composition at pH 6 or less, the treatment composition comprising sodium formaldehyde sulfoxylate, water, and a ketone. The resulting decolorized synthetic polymer is then separated from the treatment composition.

Abstract: A novel cationic bleach activator having an enhanced hydrolytic stability is provided. The novel cationic bleach activator also leads to a reduction in strength loss of cotton fibers compared to conventional hot peroxide bleaching, and achieves this reduction in strength loss without a loss of whiteness. Bleaching compositions and detergent compositions comprising the novel cationic bleach activator also are provided. A method of bleaching cellulosic fibers, such as cotton fibers, and a method for removing a stain or discoloration from an article are further provided.

Abstract: A compound of formula (I): wherein R? is hydrogen, optionally substituted (C1-6)alkyl or optionally substituted aryl; R? is hydrogen, optionally substituted (C1-6)alkyl or optionally substituted aryl; or R? and R? together form an optionally substituted 5 or 6 membered heterocyclic ring with or without additional heteroatoms; R1 is (C1-6)alkyl which is unsubstituted or substituted by fluoro, a hydroxy group which is optionally protected by a removable hydroxy protecting group, or by an amino group which is optionally protected by a removable amino protecting group; R2 is hydrogen or methyl; and —CO2R3 is carboxy or a carboxylate anion or the group R3 is a removable carboxy protecting group. This invention also relates to processes for its preparation, intermediates and pharmaceutical compositions comprising compounds of formula (I).

Abstract: The present invention provides a sock containing a coating applied to at least a portion of a surface of the sock for sensing pressure points on a patient's foot. The coating material comprises a pressure-sensitive film comprised of oxygen-sensitive photo luminescent probe molecules dispersed within a polymer matrix, and, optionally, an inorganic pigment. Areas of increased pressure can be detected by correspondence to areas on the film of increased fluorescence intensity. The coating material can also be comprised of a coloring agent or dye such that after the sock has been worn for a period of time, in those areas of the foot susceptible to pressure points, the coating material transfers from the interior of the sock and adheres to the foot in those points. The present invention is particularly applicable to persons having diabetic neuropathic feet wherein portions of the foot may be insensitive to pressure.

Abstract: Derivatives of mutiline of formula (1A) and pharmaceutically acceptable salts and derivatives thereof, in which R1 is ethyl or vinyl, Y is a carbamoyloxy group, in which the N-atom is unsubstituted, or mono- or di-substituted, are useful in the treatment of bacterial infections.

Abstract: Nonmutagenic, highly twisted derivatives of benzidine of the following formula ##STR1## useful as intermediates for the preparation of various organic pigments were obtained. The benzidine derivatives are significantly rotated about the biphenyl linkage due to bulky substituents at the R.sub.2 and/or R.sub.4 positions. Bisazomethine, disaoacetoacetanilide, disazopyrazolone, disazobenzimidazolone and disazonaphthol pigments prepared from these highly twisted benzidines exhibit hypsochromic spectral shifts relative to pigments prepared from other benzidine compounds with less twist about the biphenyl linkage, for instance, other benzidine compounds in which all four R.sub.2 and R.sub.4 represent H. Greenish-yellow, yellow, orange, red and brown pigments obtained from the twisted benzidines are nonmutagenic in the standard Ames test and Prival modification.
