CODEN: POXXA7. CLASS: IC: A61K007-06. APPLICATION: PL 78-204863 22 Feb 1978. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) A detergent base for shampoos with relatively low viscosity is prepd. contg. 50-60% (by wt.) of Na polyoxyethylene lauryl sulfate (I) [9004-82-4] with ethoxylation degree, n = 3-4, ~10% polyoxyethylene lauryl ether (II) [9002-92-0] (n = 3-4 and n = 10), 1-5% Na lactate [72-17-3], and H2O. Thus, 7143 kg of water soln. contg. 70% I (n = 4) was mixed with a soln. contg. 200 kg 50% Na lactate soln., 400 kg II (n = 10), 500 kg II (n = 4), and 1757 kg H2O. The final product contained I (n = 4), II (n = 4), II (n = 10), Na lactate, and water (50, 5, 4, 1, and 40%, resp.) (by wt.). .

CLASS: IC: C02F001-44; B01D013-00. ICA: D21C011-00. APPLICATION: JP 82-18014 6 Feb 1982. DOCUMENT TYPE: Patent CA Section: 60 (Waste Treatment and Disposal) Section cross-reference(s): 43 Spent semipermeable membranes made of polysulfone, sulfonated polysulfone, polyether sulfone, polyfluorovinylidene, polyacrylonitrile, or chlorinated PVC for pulp effluent treatment is regenerated by treatment in an aq. soln. contg. a surfactant and an oxidizing agent (ClO- or H2O2) at pH >10 and >55°. Thus, a spent polysulfone permeable membrane with a water permeation rate (1) 50 L/m2 is regenerated in a soln. contg. 0.There are some commonly used reagents with their cas registry numbers 683-10-3 and 9004-82-4 in this article.5 g Neogen R [11067-82-6] and 250 ppm NaClO at pH 12.5. The 1 of the regenerated membrane is 190 L/m2, a 93.3% recovery compared to 66.7% when no oxidizing agent is used. .
