  • Patent number: 5302658
    Abstract: A method is described for making an emulsion in which a mixture is formed containing a polysiloxane and a primary nonionic surfactant having an HLB value of 10 to 19. There is added to the mixture a first portion of surfactant free water gradually in a series of separate incremental steps. This is followed by the addition to the mixture of a secondary nonionic surfactant having an HLB value of 1.8-15. The mixture is stirred until the particle size of the polysiloxane in the mixture is in the range of 1-100 microns. A second portion of water is added to the mixture in an amount sufficient to provide a total content of water in the product of 25-65 percent by weight.

  • Patent number: 5300286
    Abstract: A silicone oil-in-water emulsion composition and a method of topically treating human skin with the composition. The emulsion constitutes water, a silicone oil, and at least two nonionic emulsifiers. Each nonionic emulsifier is a solid at room temperature. One nonionic emulsifier has an HLB value less than 8.0, while the other nonionic emulsifiers has an HLB value greater than 15.0.

  • Patent number: 5152924
    Abstract: Disclosed are emulsions which do not rust or corrode steel surfaces and further do not contain rust or corrosion inhibiting additives. The emulsions encompassed in this invention are produced using mechanical or emulsion polymerization emulsification methods. The mechanically produced emulsions must contain at least one cationic surfactant containing an anion which has a parent acid with a pK.sub.a of 3 or greater. The emulsion produced using emulsion polymerization methods are produced from (A) at least one cationic surfactant containing an anion which has a parent acid with a pK.sub.a of 3 or greater; (B) a basic or strongly basic catalyst; and (C) a catalyst neutralizer selected from acids having a pK.sub.a of 3 or greater and having the capability of neutralizing the catalyst. These emulsions are useful in applications where they might come in contact with steel surfaces.

  • Patent number: 5064694
    Abstract: This invention pertains to the use of silicone fine and micro emulsions in the web printing process. The use of the fine and micro emulsions provide improved antistatic and antimarring properties to the paper. They also have improved wetting onto the applicator roll and are dilution stable.

  • Patent number: 4733677
    Abstract: Hair fixative preparations suitable for application to hair without subsequent rinsing are disclosed. The preparations are clear, aqueous mixtures of polydiorganosiloxane and a cationic, organic polymer. The preparations are used for setting hair and may be formulated into lotion and gel type products with superior aesthetics because of the clarity of the mixtures. The preparations are effective in providing flexible, long-lasting hold for hair styles.

  • Patent number: 4620878
    Abstract: A method of preparing fine polyorganosiloxane emulsions with an average particle size of less than 0.3 micron and polyorganosiloxane microemulsions with an average particle size of less than 0.14 micron is described. A translucent oil concentrate is prepared by mixing a polyorganosiloxane which contains polar groups, a surfactant which is insoluble in the polyorganosiloxane, and sufficient water to obtain a translucent mixture. The translucent oil concentrate is then rapidly dispersed in water to form the desired fine emulsion or microemulsion. In general, if the translucent oil concentrate is not transparent a fine emulsion with an average particle size of less than 0.3 micron is obtained; whereas, if the oil concentrate is transparent, a microemulsion with an average particle size of less than 0.14 micron is obtained.

  • Patent number: 4501619
    Abstract: Highly stable emulsions of carboxyl-containing silicone fluids in water are prepared by using a combination of two surfactants. The first, or primary surfactant, has the formula RO(C.sub.m H.sub.2m O).sub.n H, where R is a hydrocarbon lipophile, m has a value of 1, 2, or 3, and n has an average value greater than 15. The second or cosurfactant, is selected from fatty acid esters of sorbitol and surfactants having the formula R'O(C.sub.p H.sub.2p O).sub.q H, wherein R' is a hydrocarbon lipophile, p has a value of 1, 2, or 3 and q has a value such that the cosurfactant is just insoluble in the carboxyl-containing silicone fluid.

  • Patent number: 4477514
    Abstract: A method for improving properties of a cellulosic textile fabric is disclosed. The fabric is first impregnated with an aqueous emulsion of a carboxyfunctional silicone fluid stabilized by a nonionic surfactant having a particular HLB value, and then heated to crosslink the carboxyfunctional silicone fluid.

  • Patent number: 4122029
    Abstract: Stable emulsions of a polar liquid in a non-polar base liquid are prepared with the cooperating action of a mixture of a water-in-oil surfactant having an HLB value of from 2 to 10 and certain polydiorganosiloxane-polyoxyalkylene copolymers. An emulsion of interest is an anti-perspirant composition comprising an aqueous solution of aluminum chlorhydrate as the polar liquid dispersed in cyclopolydimethylsiloxanes as the non-polar base liquid, using a mixture of nonylphenoxy polyethoxyethanol and a copolymer of a trimethylsiloxane-endblocked polydimethylsiloxane containing a minor amount of methylhydrogensiloxane units and an allyloxy-endblocked polyoxyethylenepolyoxypropylene copolymer.
