A method for compacting powdery compositions wherein the composition is compacted down to a reduced volume and the composition is then maintained at constant volume until the solid compact product is obtained.

Method for compacting a powdery composition at constant volume

The invention relates to a double-layered compacted solid water-purification product, comprising at least one first layer and at least one second layer, characterized in that the first layer comprises at least one flocculating system and at least one dispersion system, the second layer comprises at least one disinfectant which liberates free chlorine on contact with water and at least one excipient for the disinfectant, whereby said excipient releases the disinfectant into the water at a controlled rate such that the combination of excipient and disinfectant releases 0.1 to 100 mg/l of free chlorine per hour. The invention further relates to the method for production of such a product.

Double-layered compacted solid water-purification product

The present invention relates to tablets allowing hot drinks to be prepared by lixiviation and especially coffee. It also relates to the preparation method by which said tablets may be made.

Compact plant powder product, method of making same, and use in preparing a hot drink

The present invention relates to a compacted solid product for water purification comprising:&#x2014;at least a first layer comprising at least a coagulant/flocculant system comprising at least one polyvalent inorganic salt, at least one water-soluble cationic polymer and at least one high-molecular-weight anionic polymer,&#x2014;at least a second layer comprising at least one disinfectant that releases active chlorine on contact with water, characterized in that said coagulant/flocculant system moreover comprises a sodium alginate. The invention also relates to the method for preparing such a product.

Two-layer compacted solid product for water potabilization and preparation method

Silicone coating on various soft supports, for instance textiles, made of synthetic polymers (polyamide, polyester) provides an efficient method for producing water impermeable and water permeable coatings, on soft supports, said method enabling to improve permeability to water vapor of the silicones while preserving impermeability to water. The inventive method enabling this consists mainly in: coating one of the surfaces of the support with a film formed by an invert water-in-oil silicone emulsion comprising a continuous oily silicone phase phi s, crosslinkable into elastomer and including a polyorganosiloxane (POS) A crosslinkable by addition polymerization, by cationic process or free-radical process; optionally a crosslinking organosilicon compound B; and optionally at least a catalyst C; an aqueous phase phi a; a stabilizing agent; and in ensuring crosslinking of the silicone phase phi s and elimination of water. The invention also concerns water impermeable and water vapor permeable soft polyamide or polyester substrates obtained by using an invert water-in-oil silicone emulsion.

Use of a crosslinkable silicone-based inverse emulsion for producing 'breathable waterproof' coatings

The invention concerns a coating composition, in particular a paint comprising (A) 3 to 30 parts of a latex consisting of organic (co)polymers having a glass transition temperature ranging between &minus;20&deg; C. and 50&deg; C.; (B) 0.05 to 5 parts of an epoxyfunctionalized polyorganosiloxane emulsion; (C) and 100 parts of mineral fillers.

Coating compositions containing functionalized silicones

Process for combating the appearance of mist during the coating of flexible supports with a crosslinkable liquid silicone composition in a roll device

The invention concerns a cosmetic composition comprising a specific functionalized organopolysiloxane which is linear or cyclic. Said functionalized organopolysiloxane is used as emollient and/or carrier and/or anti-transfer agent in cosmetic compositions.

Cosmetic composition comprising a functionalized polyorganosiloxane

The invention concerns a method for preparing high purity polyorganosiloxanes with arylalkyl function(s) by: hydrosilylation of a hydrogenopolyorganosiloxane, reagent (SiH), and an aromatic monovinyl compound, reagent (Vi), with simultaneous introduction of reagent (SiH) and reagent (Vi), in a reaction medium containing an inert solvent and a hydrosilylation catalyst; then elimination of the solvent, the possible residual reagents (SiH) and (Vi), and/or hydrogenation, the hydrogenation process being optionally followed by an elimination process (or another elimination process) of the products other than polyorganosiloxanes with arylalkyl function(s). The resulting silicones with arylalkyl function(s) can be used as emollients and/or carriers in cosmetic compositions, or as solubilizing agents and emollients in perfume compositions.

Method for preparing silicones with arylalkyl function(s) by hydrosilylation

The invention concerns a perfume composition comprising a perfume base and a lipophilic solubilizing agent based on at least an organopolysiloxane having according to Hansen solubility parameter the following characteristics: &dgr; London interactions ranging from (8) to (21) (J/cm ) , &dgr; of Keesom interactions greater than 0 and capable of reaching 25 (J/cm ) , &dgr; of hydrogen binding ranging from (0) to (23) (J/cm ) . Said organotrisiloxanes with polar or polarizsable function of formula (I) are used as solubilizing agents and emollients in perfume composition.

Perfume composition using organopolysiloxanes

The invention concerns a novel cross-linkable composition and its use for preparing novel polyurethane films. The cross-linkable composition comprises (a) 20 to 50 wt. % of polyisocyanate, (b) 50 to 80 wt. % of acrylic oligomer containing hydroxyl groupings whose content in weight relative to the acrylic oligomer is between 2.5 and 4.5% and (c) 1 to 10 wt. % of a silicon fluid of formula (1).

Cross-linkable compositions containing functionalized silicon fluids and use of these compositions for preparing polyurethane films

A rubber formulation including (a) a hydrogenated nitrile rubber, (b) an organopolysiloxane, (c) a cross-linking controller selected from (i) an ester or polyester of acrylic or methacrylic acid with a polyhydric alcohol, (ii) an amide or polyamide of acrylic or methacrylic acid with a polyamine, (iii) an alkoxysilane having a C.dbd.C double bond, an amino group or a mercapto group and (iv) triallyl isocyanate, (d) an optional filler, and (e) a peroxide crosslinking agent. The rubber formulation is prepared by mixing together (a') a hydrogenated nitrile rubber composition having added therein an optional filler, (b') an organopolysiloxane composition having added therein an optional filler, and (c) the crosslinking controller, and thereafter adding (e) the peroxide crosslinking agent.
