  • Method of preparing hydrophobic precipitated silica
    Patent number: 5908660
    Abstract: A method for the preparation of hydrophobic precipitated silicas which are useful, for example, as reinforcing fillers in rubber compositions. The method comprises two steps, where in the first step an aqueous suspension of precipitated silica is contacted with an organosilicon compound in the presence of a catalytic amount of an acid to effect hydrophobing of the precipitated silica. In the second step the aqueous suspension of the hydrophobic precipitated silica is contacted with a water-immiscible organic solvent at a solvent to silica weight ratio greater than 5:1 to effect separation of the hydrophobic precipitated silica from the aqueous phase.

  • Compositions and process for treating hair
    Patent number: 4601902
    Abstract: A hair treating composition which comprises (1) a silane or a polydiorganosiloxane having quaternary ammonium substituted groups attached to silicon, (2) a polydiorganosiloxane having silicon-bonded substituents which are amino-substituted hydrocarbon groups, (3) one or more surfactants, and (4) water. The compositions can be formulated as e.g. hair conditioning agents or as shampoos.
