  • Patent number: 7385001
    Abstract: High viscosity silicone compositions such as silicone gums, silicone rubbers, silicone elastomers, and silicone resins, are emulsified by mechanical inversion in which silicone water-in-oil (W/O) emulsions are inverted to silicone oil-in-water (O/W) emulsions. Silicone resins with a viscosity of about one billion centistoke (mm2/s), i.e., 1,000,000,000 centistoke (mm2/s) have been emulsified. These silicone O/W emulsions are useful in personal care products where they are capable of providing improved aesthetics. They are also useful in products used in the paper industry and medical industry. The silicone O/W emulsions are easier to handle than the high viscosity silicone in the emulsion, which enables the emulsions to mixed with other emulsions or other water-soluble ingredients.

  • Patent number: 6706811
    Abstract: The invention discloses an efficient and convenient method for the preparation of an aqueous emulsion of an organopolysiloxane having long-chain alkyl groups bonded to the silicon atoms. Instead of dispersing and emulsifying an organopolysiloxane modified in advance with long-chain alkyl groups in an aqueous medium, as is the case in the prior art method, an organohydrogenpolysiloxane having silicon-bonded hydrogen atoms and a long-chain &agr;-olefin compound are co-emulsified in an aqueous medium containing a surface active agent and this aqueous emulsion is heated under agitation with addition of a catalytic platinum compound so as to effect the in situ hydrosilation reaction between the silicon-bonded hydrogen atoms in the organohydrogenpolysiloxane and the ethylenically unsaturated bonds in the &agr;-olefin compound. The aqueous emulsion prepared by the inventive method exhibits excellent stability against long-term storage, dilution with water and mechanical shearing force.

    Abstract: It has been discovered that organoamine modified siloxane alkoxylates overcome the antagonism associated with nonionic trisiloxane alkoxylates on pesticide uptake in plants. The organoamine modified siloxane alkoxylates of the present invention have the average general formula: AMe.sub.2 SiO[(Me).sub.2 SiO].sub.x [MeSi(Z)O].sub.y SiMe.sub.2 A, wherein x=0 to 1, y=0 to 2, with the proviso than when y=0, A is Z, A=is Z or Me, Z=RO(R.sup.1).sub.n R.sup.2 N(R.sup.3).sub.2, R is a divalent organic group having from 2 to 4 carbon atoms, R.sup.1 is an alkyleneoxide group containing 2 to 4 carbon atoms, R.sup.2 is a divalent organic group containing 2 to 6 carbons, R.sup.3 may be hydrogen, an alkyl radical with 1 to 4 carbons, an amino alkyl of one to four carbons, or an alkyl of 2 to 4 carbon atoms which may have hydroxy substitutions thereon. Each R.sup.3 may be the same or different.When R.sup.1 is oxyethylene, n is from 1 to 10, preferably 2 to 5. When R.sup.

  • Patent number: 5973066
    Abstract: An oil-in-water aqueous organopolysiloxane emulsion suitable as an adjuvant, in particular, in a toiletry preparation such as a hair-care treatment preparation is disclosed by using a unique emulsification system including a quaternary ammonium chloride as a cationic surface active agent, in order to provide a solution for the problem of a dilemma between the use of a C.sub.16 or lower-alkyl quaternary ammonium salt having high emulsification power but exhibiting irritativeness to the human body and the use of a higher-alkyl quaternary ammonium salt having lower emulsification power but exhibiting no irritativeness.
