The present invention relates especially to a composition for manufacturing an article comprising one or more superposed layers each less than 5 centimeters thick, comprising a hydraulic binder and at least one compound chosen from an organic compound comprising at least two hydrophilic functions and a hydrophobic chain, and a polyamide oligomer. The use of these additives in the presence of hydraulic binder allows the manufacture of articles and coatings with good protection against water uptake, satisfactory water resistance and good mechanical properties such as breaking strength.

Hydraulic binder composition

Hydrophilized compositions including normally hydrophobic thermoplastic polymers, e.g., polypropylene, and hydrophilizing amounts of anionic surfactants, e.g., sodium alkylsulfonates, are shaped into such articles as molded objects having hydrophilic surfaces.

The present invention relates to a novel agent for promoting adhesion to a heat-insulating surface and in particular to a polystyrene surface, especially when wet or under the effect of a large variation in temperature. The invention also relates to the use of the said agent in a water-insoluble film-forming polymer composition or in a mineral binder composition for applications in the construction field and more particularly in external heat-insulation systems.

The present invention relates to novel coating compositions, or surface-treatment compositions, in particular paint compositions. These compositions can be used in various applications, such as interior or exterior water-based paints, render, varnish, a semi-thick coating, formulations for finishes for architectural textiles, rigid or flexible plastic surfaces, or surface-protection products.

Hydraulic binders, such as cements, mortars with enhanced aging properties, are described. More particularly, hydraulic binders based on mineral silicates are described having greater aging strength, a method for making said binders and their uses and articles obtained from same. An organic compound comprising two hydrophilic functions and a hydrophobic chain such as adipic acid are added to the hydraulic binder to slow down the water uptake rate of said binder.

The invention concerns water dispersible granulates comprising: at least a hydrophobic perfume (P), in the form of droplets, finely divided in and encapsulated by a water soluble or water dispersible solid organic matrix (MO) selected among: polypeptides (PP) of plant or synthetic origin; polyelectrolytes (PE) belonging to the family of weak polyacids; or their mixtures; and at least an emulsifying agent (AE) at the droplet/matrix interface. The invention also concerns a method, in two steps, for preparing said granulates, the first step consisting in preparing an emulsion in water comprising at least a hydrophobic perfume (P), at least an emulsifying agent (AE); and said water soluble or water dispersible organic matrix (MO), the second step consisting in drying said emulsion until a granulate is formed.

Laundry treatment compositions, especially detergent compositions or rinse conditioners, which deposit cellulosic polymers or related polysaccharide fabric rebuild agents onto textile fabrics are described. Such agents are used for laundering cellulosic fabrics such as cotton, to compensate for gradual loss of fibrous material on repeated washing. Preferred rebuild agents are cellulose monoacetate, cellulose hemisuccinate and other cellulose esters.

A system in the form of an aqueous dispersion or granules containing at least one liquid, waxy or pasty non-ionic surfactant and an alkali metal silicate. The system is prepared using a concentrated aqueous alkali metal silicate solution as the continuous liquid phase optionally containing glycerol, in which is dispersed at least one liquid, pasty or waxy non-ionic surfactant that is non-miscible or poorly compatible with said concentrated alkali metal silicate solution, and at least one non-ionic or anionic surfactant that is compatible with said concentrated alkali metal silicate solution and capable of causing the dispersion of said liquid, pasty or waxy non-ionic surfactant(s) in said concentrated alkali metal silicate solution. The resulting dispersion is optionally dried to produce a rigid alkali metal silicate shell encapsulating droplets or particles of the liquid, pasty or waxy non-ionic surfactant(s). The system may optionally further contain at least one other detergent builder and may be used as a component of a detergent composition, particularly for use in washing machines, or as the detergent composition itself.
