• Mulls containing chain structure clay suspension aids
  申请人：THE PROCTER & GAMBLE COMPANY

  公开号：EP0034387A2

  公开（公告）日：1981-08-26

  A liquid mull is provided having improved physical stability, consisting of a liquid phase, comprising a major proportion of a nonionic surfactant and optionally a minor proportion of a nonaqueous solvent, and a dispersed solid phase comprising a particulate material which is insoluble in the liquid phase of the mull. From 1 % to 15% by weight of the composition of a chain structure type clay is included to aid the physical stability of the mull, so that insoluble particulate materials such as builders having ordinary particle sizes may also be incorporated. Preferred compositions are substantially anhydrous to allowthe optional inclusion of water sensi. tive detergency adjuvants such as enzymes or bleaches. The compositions may optionally contain up to 25% of a further dispersion aid selected from anionic surfactants, cationic surfactants, zwitterionic surfactants and hydrotropic materials. Such mulls have utility, for example, as detergent compositions.

  本发明提供了一种具有更好物理稳定性的液体闷闷不乐剂，它由液相和分散固相组成，液相主要由非离子表面活性剂和少量非水溶剂组成，分散固相由不溶于闷闷不乐剂液相的颗粒材料组成。按重量计，在组合物中加入 1%至 15%的链状结构粘土，以提高泥浆的物理稳定性，这样也可以加入不溶于泥浆的颗粒材料，如具有普通粒度的建筑材料。优选的组合物基本上是无水的，这样就可以选择性地加入对水敏感的去污佐剂，如酶或漂白剂。组合物还可以选择性地含有高达 25% 的其它分散助剂，这些助剂选自阴离子表面活性剂、阳离子表面活性剂、齐聚亚铵盐表面活性剂和亲水材料。例如，这种混合物可用作洗涤剂组合物。

  Polymers containing by weight (i) from about 50 to about 85 parts of units derived from at least one monomer (FM) having the formula wherein R1 is straight or branched-chain perfluoroalkyl containing 4-20 carbons; R is H or CH3; and n is an integer from 1-15; and (ii) from about 50 to about 15 parts of units derived from 3-chloro-2-hydroxypropyl methacrylate and/or acrylate (CHPM/A) or their bromo analogs. Preferably, the polymers contain by weight between 65 and 75 parts of units derived from FM and 35-25 parts of units derived from CHPM/A, particularly a copolymer consisting essentially by weight of 75 percent of a mixture of FM and 25 percent of CHPM. Polymers impart superior oil- and water-repellency and anti-soiling characteristics to fibrous substrates, and may be applied as a spin finish, particularly to nylon filaments.

  公开号：EP0195676A2

  公开（公告）日：1986-09-24

  A method of bleaching textile materials in water at lower temperatures and reduced time intervals wherein: a source of bromide ions is added to the water to impart an initial concentration between 1 and 25 ppm; a chlorine ion source is added to the water to yield an initial concentration between 25 and 90 ppm; the wash water and textile materials are agitated for an interval between 30 seconds and 5 minutes; and the bleached textiles are recovered. The process may be carried out at temperatures between 80° and 120°F. Preferred ion donating sources are sodium bromide and sodium hypochlorite. If desired, the sodium bromide may be compounded with conventional detergent formulations.
