Title: Process for improving the quality of hair
IPC: A45D7/00
Filed: 1974-03-07
Abstract: 1466621 Setting hair L'OREAL 7 March 1974 [8 March 1973] 10319/74 Heading D1P 15 to 70% of the cystine in living hair (i.e. hair on the head) is converted to lanthionine, the hair not being subject to any extension forces during the conversion. (The conversion involves the replacement of the -S-S- linkage of cystine with the -S- linkage of lanthionine). Lanthionised hair is more elastic in the wet state, so that fewer breakages occur on combing after shampooing; it retains its set longer after subsequent wavings, it is more permeable e.g. to dye and bleach and is less soluble in alkali. Undegraded hair should be at least 25% lanthionised; hair degraded by previous treatment the degree of lanthionisation should be reduced (down to a minimum of 15% by the proportion of cystine that has been destroyed by the damage. Preferably the hair is treated with an aqueous composition (gel, cream or solution) having a pH of 10.5 to 13 at 25 to 50C for 10 to 60 minutes. The hair may be covered with a cap during treatment to retain moisture. The pH is produced by calcium, lithium, sodium or potassium oxide. Lanthionisation is assisted by the presence of up to 5 moles/litre of an electrolyte having a neutral oxidation-reduction potential, e.g. sodium or calcium chloride, lithium bromide or sodium, potassium or calcium sulphate or up to 3 x 10<SP>-2</SP> moles/litre of an alkali metal or alkaline earth metal sulphide (e.g. S r S) or 10<SP>-3</SP> to 10<SP>-1</SP> moles/litre of an alkali metal or alkaline earth metal sulphite (e.g. Na 2 SO 3 ), up to 3 x 10<SP>-2</SP> moles/litre of cetyl-trimethylammonium bromide or up to 10<SP>-1</SP> moles/litre of a quaternary ammonium hydroxide or up to 1 mole per litre of guanidine carbonatehydroxyethyl cellulose, oleic acid, oleyl alcohol, polyoxyethylene glycol and nonylphenol polyethylene ethers may also be present. Lanthionisation is more rapid if the hair is dry before the treating composition is applied. Specification 1466622 describes converting 10 to 50% of the cystine present in living hair, the hair being tensioned during the treatment at a temperature of 25 to 120C.

Title: Fertilizer materials
Inventor: BRADLEY JOHN KENNETH
IPC: C05B11/06
Filed: 1958-04-01
Abstract: <FORM:0916422/III/1> A compound fertilizer is produced by reacting potassium chloride solid or solution with nitric and sulphuric acids to produce a liquid product containing free acid, removing nitrosyl chloride and chlorine formed, and treating the liquid product with phosphoric acid and/or phosphate rock.  HNO3 may be 40-95%, H2SO4 may be 70-98% and the acids may be in mole ratio 1:10 to 10:1 with 1,3-2,5 moles mixed acids being used per mole KCl.  The reaction may be at above 80 DEG C. under normal, sub-, or superatmospheric pressure and the water content of the mixed acids should be 20-40%. The acids should be at least 10% excess yielding a product containing KNO3 and KHSO4.  The phosphate rock may be calcium or alumino phosphate particulate rocks and the phosphoric acid may be 50-70% to provide a P content at least 15%.  When phosphate rock is used CaSO4 may be filtered off.  The liquid product after phosphate treatment may be neutralized with 25-33% aqueous or anhydrous ammonia, or aqueous or anhydrous KOH or K2CO3 with vigorous agitation. The granulated dried product may be mixed with phosphate, superphosphates, potassium, or ammonium salts, or fillers, e.g. chalk, gypsum, or brick dust.  Fertilizers with desired NKP ratios may be obtained by selection of proportions of reactants used. KCl and mixed HNO3 and H2SO4 are reacted in series-connected reactors 1, 2, 3, and the liquid product containing acids, KHSO4, and KNO3 is treated with phosphate rock in series-connected reactors 4, 5.  CaSO4 is filtered off at 6 and the filtrate containing H3PO4, HNO3 and nitrates is neutralized to pH 4,5 in 7 with ammonia.  The resulting product containing KNO3 and/or KHSO4, mono-ammonium phosphate, (NH4)2 SO4, with or without NH4NO3 is granulated and dried.  The NOCl+Cl2 from 1, 2, 3 is washed with a countercurrent of conc. H2SO4 in 8 to yield Cl2+HCl gas, which is washed with H2O in 9 to yield Cl2, which is recovered, and aqueous HCl which may be passed to reactor 1 or recovered.  The mixture of nitrososulphuric and sulphuric acids from 8 is contacted with H2O or dilute HNO3 and lair or O2 in 10 to yield a mixture of HNO3 and H2SO4, which is recycled to reactor 1, and oxides of nitrogen, which are converted to dilute HNO3 by H2O and O2 in 11.  The HNO3 may be recycled to 10 or to reactor 1.  Reactor 4 and filter 6 may be eliminated when H3PO4 is used alone and the product before ammoniation still contains bisulphate.
