Abstract: A method of enhancing the dispersibility of alpha-alumina monohydrate wherein there is formed a mixture of an alpha-alumnina monohydrate, water, and a dispersibility enhancer comprising an effective amount of a monobasic acid, a salt selected from the group consisting of salts having the formula MX wherein M is a polyvalent metal cation constituent for which the solubility product KSP of the corresponding metal hydroxide is less than 10−20 and wherein X is an anion constituent derived from a monovalent acid having an ionization constant KA greater than 10+1 and certain phosphorus and antimony chlorides, followed by drying the mixture, without aging, to produce a dried, alpha-alumina monohydrate having advanced water dispersibility.

Abstract: Water-redispersible granules prepared by drying a water-in-oil emulsion including at least one active material in the form of a hydrophobic liquid; at least one water-soluble compound capable of forming, during the drying process, a solid continuous film in which droplets of the hydrophobic active material are trapped; water; and at least one main surfactant with a binary water-surfactant phase diagram comprising an isotropic phase which is fluid at 25° C. up to a surfactant concentration of at least 50% by weight, followed at higher concentrations by a hexagonal, cubic or lamellar liquid crystal phase that is stable at least up to 65° C.

Abstract: Dispersion powders with a reduced tendency to autoignition are obtained by adding antioxidants to dispersions before spray drying or to dispersion powders after spray drying.

Abstract: Water-redispersible granules including at least one active material in the form of a hydrophobic liquid, at least one non-ionic surfactant selected from polyoxyalkylene derivatives, and at least one water-soluble compound selected from polyelectrolytes belonging to the weak polyacid family are disclosed. A method for prepang such granules by preparing an aqueous emulsion of at least one active material, at least one non-ionic surfactant and at least one water-soluble compound, and drying the resulting emulsion, is also disclosed.

Abstract: The present invention relates to a foam control composition and to its use in foaming systems. More particularly, this invention relates to a foam control composition comprising a polysiloxane and a resin-filler made from MQ resins having at least one polyoxyalkylene group. The compositions of this invention exhibit excellent defoam effects and antifoam persistency.

Abstract: The present invention is in the area of administration forms and delivery systems for drugs, vaccines and other biologically active agents. More specifically the invention is related to the preparation of suspensions of colloidal solid lipid particles (SLPs) of predominantly anisometrical shape with the lipid matrix being in a stable polymorphic modification and of suspensions of micron and submicron particles of bioactive agents (PBAs); as well as to the use of such suspensions or the lyophilizates thereof as delivery systems primarily for the parenteral administration of preferably poorly water-soluble bioactive substances, particularly drugs, and to their use in cosmetic, food and agricultural products. SLPs and PBAs are prepared by the following emulsification process: (1) A solid lipid or bioactive agent or a mixture of solid lipids or bioactive agents is melted.

Abstract: The invention relates to the production of polyaspartic acid homo- and copolymers by biotechnological processes and to the use of the resulting products (for influencing the crystallization or agglomeration behavior of sparingly soluble salts or solids in aqueous systems).

Abstract: This invention provides water-based compositions, particularly coating, ink, and agricultural compositions, manifesting reduced equilibrium and dynamic surface tension by the incorporation of a surface tension reducing amount of certain cyclic urea compounds of the structure where R is a C6 to C12 alkyl group or R″O—(CH2)m—, R′ is hydrogen or methyl, R″ is a C4 to C12 alkyl group, m is 2-4 and n is 1 or 2.

Abstract: The present invention relates to a boron-containing aqueous solution comprising at least one amino compound and/or one organic polyhydroxylated compound, characterized in that: it comprises a theoretical amount of B2O3 of between 25 and 55% by weight, at least one solubilized complex between at least one boron-containing product and the amino compound and/or one organic polyhydroxylated compound, and optionally at least one biocide and/or one antifoam and/or one anionic or non-ionic surfactant, it is obtained from at least one initial boron-containing solute consisting of a mixture of at least one borate, boric acid and/or B2O3 and optionally at least one strong base, and its pH is between 6 and 9. Application: Addition to starch paste, brightening products or biocides and for the decontamination of radioactive materials, inter alia.
