There is disclosed a foam control composition comprising (I) a silicone defoamer reaction product and (II) a silicone glycol copolymer, which composition is particularly effective in defoaming highly acidic or highly basic aqueous systems. The compositions of the present invention can further comprise (III) a finely divided filler, and/or (IV) a trimethylsilyl or hydroxyl endblocked polyorganosiloxane.

Silicone foam control compositions

There is disclosed a foam control composition comprising (I) a silicone defoamer reaction product and (II) a silicone glycol copolymer, which composition is particularly effective in defoaming highly acidic or highly basic aqueous systems. Component (I) is prepared by heating a mixture of (i) a polyorganosiloxane fluid, (ii) a resinous silicon compound, (iii) a finely divided filler and (iv) a catalytic amount of a compound for promoting the reaction of the other components at a temperature of 50.degree. C. to 300.degree. C.

Silicone foam control composition

A method of coloring hair in which there is applied to the hair a hair coloring preparation consisting essentially of a water based organic solvent free mixture of 0.01 to 10.0 percent by weight of a temporary dye color which is a water soluble acid dye, 0.1 to 10.0 percent by weight of a quaternary ammonium functional silane, the remainder of the mixture being water. The mixture is combed through the hair and the hair is allowed to dry without rinsing.

Method of coloring hair with water soluble acid dyes

A method of making the surface of a fluorochemically treated substrate antimicrobially active by exposing the fluorochemically treated substrate to a compound selected from the group consisting of inorganic acids and organic acids. Exemplary of the acids are sulfuric, hydrofluoric, hydrochloric, hydrobromic, hydriodic, nitric, perchloric, phosphoric, boric, acetic, adipic, anisic, benzoic, butyric, fumaric, gallic, glutaric, glycolic, lactic, lauric, tannic, and tartaric acids.

Antimicrobial flourochemically treated plastic (nylon) surfaces

A method of enchancing the cleanability and facilitating the removal of algae and other microorganisms from surfaces prone to biofouling by immobilizing on said surfaces and bonding thereto a coating of organosilanes, forming on the coated surfaces a layer of dead cells of the algae and other microorganisms, utilizing the layer of dead cells and inherent release characteristics of silicone surface as a release medium to facilitate removal of succeeding layers of algae and other microorganisms that accumulate thereon, and cleaning the surfaces by dislodging the accumulated layers from the release medium layer.

Cleaning method for water containing vessels and systems

This invention relates to a method and composition for inhibiting discoloration of the emulsions due to contact with ferrous materials. The invention comprises adding from 0.1 to 1.6 wt. %, preferably, from 0.3 to 0.9 wt. % based on the oil phase of the emulsion of one or more members of the group consisting of phosphoric acid and disodium phosphate. The invention also optionally comprises an amount of pit corrosion inhibitor selected from the group consisting of zinc pyrithione and a zinc containing siloxane resin. The invention also includes the composition of a silicone polymer in water emulsion, wherein the emulsion contains form 0.1 to 1.6 wt%, preferably, from 0.3 to 0.9 wt. % based on the oil phase of the emulsion of one or more mebers of the group consisting of phosphoric acid and disodium phosphate and optionally comprises an amount of pit corrosion inhibitor.

Method of inhibiting the discoloration of emulsions and discoloration

What is disclosed is a method of improving the adhesion of thin metal coatings to various solid substrates by pretreatment of the solid substrates using organofunctional silanes or mixtures of organofunctional silanes with organosilanes and thereafter depositing metals to form films or coatings.
