  • Reduced foam petroleum composition
    Patent number: 10010813
    Abstract: A reduced foam or reduced foam and water petroleum composition includes crude oil and a preformed antifoam emulsion. The antifoam emulsion includes a hydrophilic continuous phase and a polyorganosiloxane dispersed in the hydrophilic continuous phase. The hydrophilic continuous phase may also contain a demulsifier. The antifoam emulsion includes less than 50 weight percent of a hydrophobic solvent. A method of reducing foam or foam and water in crude oil disposed in a tank is also described.
    Type: Grant
    Filed: August 26, 2014
    Date of Patent: July 3, 2018
    Assignee: Dow Brasil Sudeste Industrial Ltda

  • OXIDATION HAIR DYEING AGENT COMPOSITION
    Publication number: 20020120989
    Abstract: An oxidation hair dyeing agent composition provides a color tone for dyed hair which is not easily affected by repeated washing with cold and hot water containing shampoo and soap, and it has superior wash resistance. The oxidation hair dyeing agent composition is characterized as containing a cyclic silicone and a silicone elastomer. As a two-component type oxidation hair dyeing agent composition, it contains as the first component a mixture of an oxidation dye precursor, a cyclic silicone, a silicone elastomer, an emulsifying agent, and water. The mixture is emulsified in water using the emulsifying agent. The second component of the composition is an aqueous hydrogen peroxide solution.
