    Abstract: Fibrous materials consisting of or containing keratinous fibres are permanently shaped by impregnating them with a solution or dispersion of a secondary or tertiary amine which is volatile in steam only to a negligible extent and then heating them with steam during shaping. Suitable amines are dihexylamine, methyloctylamine, tripentylamine, dimethylstearylamine, diethyl-palm kernel fatty amine N-methyltaurine the ammonium salt of dimethylamino acetic acid, b (dimethylamino) ethane sulphonic acid sodium salt, the ammonium or sodium salt of N, N diethylglycocoll, diethanolamine, butyl diethanolamine, triethanolamine, penta-(2-hydroxyethyl) diethylene triamine, penta-(2-hydroxypropyl) diethylene triamine and penta-(2-hydroxypropyl) dipropylene triamine. The amine maybe applied to the materials as an aqueas solution or dispersion or as a solution in a volatile organic solvent, e.g. a low molecular weight alcohol, ketone or ester, by immersion or spraying in an amount of 0.2-5% by weight based on the materials. The amine may be neutralised with an organic acid, e.g. formic or acetic acid, either in the treatment liquor or on the fibrous material. The treating composition may also contain a non-ionic wetting agent and a reducing agent, e.g. an alkali metal bisulphite, sulphite, thio sulphate or dithianite or an alkali metal salt of a hydroxy alkane sulphuric acid or a reaction product thereof with ammonia or a primary amine. After impregnation and drying the materials may be stored and made up into garments prior to shaping. Shaping may be carried out at temperatures of 100 DEG -150 DEG C. using smooth or textured rollers, dies, crimping devices or a flat iron to provide calendered, embossed, crimped and pleated or creased effects. The process may be combined with a shrink-resist finish using oxidising agents, e.g. dichlorocyanuric acid and its salts. Yarns and woven, knitted and non-woven fabrics comprising wool alone or an admixture with cotton or polyester fibres may be treated. Specification 891,217 is referred to.

    Abstract: Substituted 1,4-bis-styryl benzenes of the general formula: in which X and X1 stand for carboxylic ester groups or N-alkyl carboxylic amide groups, are prepared by reacting terephthaladehyde with an ester of a carbalkoxy-benzylphosphonic acid or with an ester of a halogenmethylbenzoic acid, with the aid of a triarylphosphine and an alkali alcoholate, and if necessary converting the ester groups of the products into amide groups. These substituted 1,4-bis-styryl benzenes are optical brightening agents (Group IV(c)). In Example 1, the methyl ester of p-chlormethylbenzoic acid is stirred with triphenylphosphine in dimethylformamide at 80 DEG C. for 3 hours; and then terephthalaldehyde followed by sodium methylate are added. The product is 1,4-bis-(para-carbmethoxy-styryl)-benzene, and this is converted, by heating it with diethanolamine, into 1,4-bis-(para-carbodiethanolamidostyryl)-benzene Example 8 refers to 1,4-bis-(meta-carbdiethanolamido-styryl)-benzene. Example 9 describes the preparation of a mixture of 1,4-bis-(para-carbethoxy-styryl) - benzene, 1,4 - bis - (metacarbmethoxy-styryl)-benzene and 1-(para-carbmethoxy-styryl) - 4-(meta1-carbmethoxy-styryl)-benzene, by reacting terephthalaldehyde with a mixture of meta- and para-carbmethoxy-benzyl-phosphonic acid diethyl ester. The mixture of 1,4-bis-styryl-benzene diesters is then reacted with diethanolamine. Example 19 states that 1,4-bis-(meta-carb-N-cyclohexylisopropanol-amidostyryl)-benzene is obtained by reacting 1,4 - bis - (meta-carbmethoxy-styryl)-benzene with N-cyclohexyl-iso-propanolamine. It is stated that X and X1 in the general formula may stand for COO.C2H4OH, and similar groups. Compounds wherein the hydrogen atoms of the hydroxy groups in both the amides and the esters are substituted by glycol ether groups are obtained by the reaction of the amides or esters with ethylene oxide or propylene oxide. Specification 813,539 is referred to.ALSO:Substituted 1, 4-bis-styryl benzenes of the general formula in which X and X1 stand for carboxylic ester groups or N-alkyl carboxylic amide groups, act as brightening agents for textiles, paper and leather. The brightening agent is preferably used in aqueous medium in amounts of about 0,0015 to 0.05% with reference to the weight of the substrate to be brightened. In Example 1, previously bleached cotton fabric is treated, for 20 minutes, in a liquor, at 50 DEG to 60 DEG C., containing 0,003 to 0,01 grams per litre of the compound having the structure and 5 grams per litre of sodium sulphate decahydrate, the liquor to fabric ratio being 50:1. After rinsing and drying, the fabric has a dazzling whiteness of good fastness to light and washing. Examples 5, 6 and 7 relate to the use of the same compound for brightening polycaprolactam fabric, yellowish paper, and soiled clothing, respectively. Example 8 describes the use of 1, 4-bis-(metacarbdiethanolamidostyryl)-benzene for brightening cotton fabric. For the preparation of the brightening agents, (see Group IV(b)). Specification 813,539 is referred to.

    Abstract: Soaps, synthetic detergents and mixtures thereof in solid form, e.g. in cake, flake, needle and powder form, are stabilized against spotting and rancidity caused by heavy metal ions such as those of iron, nickel and copper by the incorporation of an additive which is substantially free from uncombined alkali metal hydroxide comprising (a) one or more polyhydric alcohols containing more than 4 hydroxyl groups, and (b) one or more complex-forming compounds containing the group where R1 and R2 each represent -C2H4OH or -CH2COOX, X being hydrogen or an alkali metal. The total of (a) and (b) preferably amounts to 0.05-5% by weight of the composition, and the weight ratio of (a) to (b) is 2:1 to 1:1. (a) is for example manitol, xylitol, or hydrogenated wood hydrolysate, but is preferably sorbitol, while (b) may be dihydroxyethylamino-acetic acid, iminodiacetic acid, nitrilotriacetic acid, hydroxyethylethylene diamine triacetic acid, ethylene diamine triacetic acid, 1:2-diaminocyclohexane tetracetic acid, N:N1-dihydroxyethyl-1:2-diaminocyclohexane-N:N1 -diacetic acid, 2-hydroxy-1:3-diaminopropane tetracetic acid, or tetrahydroxyethyl-1:2-diaminocyclohexane, but is preferably ethylenediamine tetracetic acid. Suitable detergents, in addition to soap, include alkyl sulphates or sulphonates, alkylglycol ether sulphates, alkylaryl sulphonates, fatty acid condensates, poly-glycol ethers of alkylphenols or fatty alcohols, or cationic active compounds. Cellulose ether carboxylic acids, cellulose ethers and esters, salts of polyacrylic and polymethacrylic acids, polyvinyl compounds such as polyvinylpyrrolidone, polyglycol ethers, fatty acid alkanolamides, triethanolamine, esters of polyhydric alcohols and glucosides, glucosides themselves and ethylene condensates of such esters and glucosides, potato flour, phosphates, silicates, sodium chloride and sulphate, talc, bentonite, titanium dioxide, paraffin wax, petroleum jelly, skin protectives, disinfectants, optical brighteners and dyestuffs may also be incorporated.
