Abstract:
The present invention relates to an Automatic Dishwashing (ADW) detergent composition comprising at least one cationic polysaccharide of molecular weight of less than 1,000,000 g/mol. The invention also relates to a method for eliminating, limiting or preventing the spotting and/or filming phenomena during the washing comprising the use of a detergent composition according to claim 1.
Abstract:
Novel dicarboxylic acid diesters and admixture thereof have the formula (I): R1—OOC-A-COOR2 (I) and are advantageously prepared from fusel oils; these are particularly suited for formulation into useful solvent, cosolvent, stripping, crystallization inhibiting, cleaning and degreasing compositions.
Abstract:
A method for replacing glycol-based mutual solvents in an oil field application comprising: obtaining an alternative solvent and solvent blends and replacing all or a portion a glycol-based mutual solvent, which forms a component of an oil field formulation, with the alternative solvent or solvent blends, wherein the oil field formulation can be utilized in an oil field application.
Abstract:
The invention concerns the use as anti-UV agent, in an elastomer rubber composition, of titanium dioxide particles of not more than 20 mn in size, said particles being coated with a silica, silico-aluminate or alumina layer. The invention also concerns rubber compositions comprising such an anti-UV agent and finished products based on said composition.
Abstract:
Organophilic particles of a metal oxide chosen from alumina Al.sub.2 O.sub.3, silica SiO.sub.2, transition metal oxides, especially titanium oxide TiO.sub.2, and rare-earth metal oxides, especially cerium oxide CeO.sub.2, are prepared by reacting an aqueous-alcoholic suspension (a) of metal Oxide particles which have no pores less than 5 nm in di-meter at their surface with an anhydrous alcoholic solution (b) comprising at least one alkoxysilane of formula (1) Si(OR).sub.x R'.sub.4-x (1) in which R represents an alkyl group containing from 1 to 6 carbon atoms, R' represents a hydrocarbon group chosen from alkyl, cycloalkyl, aryl, alkylaryl, arylalkyl, alkenyl and alkynyl groups containing at least one carbon atom and x is an integer from 1 to 3, the said alcohols, which may be identical or different, containing from 1 to 5 carbon atoms.
Abstract:
The current invention relates to families of scale-inhibitors having different UV/VIS absorption profiles and their application in a method for stimulating an oilfield comprising those families.

Abstract:
Composite core/sheath particulates comprising an organic polymer core at least partly coated with calcium carbonate, these core/sheath particulates having a mean particle size not exceeding 5 .mu.m, well suited for reinforcing plastic/elastomer substrates, are conveniently converted, e.g., via calcination, into hollow calcium carbonate microbeads which comprise CaCO.sub.3 shells having a mean particle size not exceeding 5 .mu.m; such hollow microbeads are themselves well suited for enhancing the low-temperature flexibility of elastomer substrates, notably vehicle tires.
Abstract:
The invention relates to a copolymer having: A) at least one monomer unit a) derived from at least one ethylenically unsaturated aliphatic monocarboxylic or polycarboxylic acid, a corresponding anhydride, or a corresponding water-soluble salt; B) at least one monomer unit b) derived from a particular sulfonated or sulfated ethylenically unsaturated ether or at least one monomer unit (b′) derived from a sulfonated ethylenically unsaturated monomer other than (b), C) at least one monomer unit (c) derived from a monomer with the average general formula [CH2═CH—CH2—R6—O—]xP(═O)(OM)3-x. The invention also relates to a method for preparing such a copolymer, an inhibitor composition including such a copolymer, and a method for inhibiting inorganic deposits in a petroleum reservoir by means of said inhibitor composition.
Abstract:
Composite particles having a core consisting of an organic polymer and a coating including at least one aluminum, silicon, zirconium and/or transition metal oxide and/or hydroxide, and optionally containing calcium carbonate, as well as methods for preparing same, are disclosed. The use of said composite particles for preparing hollow particles with a shell of the same kind as the above-mentioned coating is also disclosed. Finally, the use of said hollow composite particles as fillers or additives in plastics and elastomers is disclosed.
