The technical field to which the invention relates.

The present invention relates to delivery systems of odoriferous substances, including particles of insoluble carrier containing silanol on the surface of the grafted silicone compound containing an amino group, a polymer containing positively charged functional groups, and aromatic substances adsorbed on the surface of the particles or the particles of the medium. Delivery systems of odoriferous substances give long-lasting scent fabrics treated with compositions containing the delivery system of odoriferous substances.

The background to the present invention

Products for treatment of tissue, such as surfactants or softeners tissues usually contain fragrances that don't just mask the odors of some components in the composition of products to care for fabrics, but also give a pleasant smell processed tissues.

Fragrances are the most expensive ingredients for processing tissues, so the creature is t the need to retain the maximum possible number of odoriferous substances in the treated tissue. This condition is primarily important for products for textiles, which are used in water, such as surfactants for washing, or the finest fabrics for rinsing. When using such products, there is a need to develop delivery systems of odoriferous substances, which are retained on the fibers, i.e. stick to the fibers during processing of the tissue and are not washed from it in the wash or rinse. Such delivery systems of odoriferous substances must also provide slow release of odoriferous substances for imparting processed tissues of long-lasting fragrance, from the average level of intensity of smell, which is not perceived as unpleasant.

In the United Kingdom patent GB 1306924 described finely dispersed silicon dioxide and micronized silica gel, used as carrier particles for fragrant oils. With the use of such particles in the carrier liquid scented oils processed into compositions in the form of a freely running powders containing not more than 70 wt.% sweet oil.

In the patent US 5840668 described scented washing powder-based surfactants. Described surfactants contain aromatic substances applied on the system carrier, comprising as a carrier of amorphous silicon dioxide. The experiments described in the text (column 7, line 58 column 9, line 26), the show is about what fragrant substances adsorbed on the particles of the medium is silicon dioxide is quickly released into the aquatic environment in the presence of even small amounts of surfactants. Thus, the delivery system of odoriferous substances is not effective for delivery of odoriferous substances in the tissue treated with surfactants described.

In the patent US 4954285 described the inclusion of particles of silicon dioxide containing adsorbed aromatic substances in the composition of the solid softener tissue activated during drying. The patent describes (column 4, lines 53-55), which is aromatized particles of silicon dioxide release fragrances when wetted with aqueous fluid. Accordingly, the patent describes particles of the composition of the softener tissues, including flavored particles of silicon dioxide with an additional water-insoluble coating for use softener tissues in the water.

In the patent US 4954285 described flavored carrier consisting of smectite particles or zeolite, with fragrant substances adsorbed on particles containing a coating of adhesive to the fabric, which preferably is a compound of Quaternary ammonium. The delivery system of odoriferous substances used in the means for washing, and the patent describes the increased intensity of the odor in fabrics washed in such means for washing, compared to what Konami, washed using a detergent containing odoriferous substances without media. However, the lack of a delivery system of odoriferous substances described in patent US 4536315, is that the use of surfactants or dispersing agents leads to rapid destruction of the coating particles in the processing of tissues, which, in turn, leads to a decrease in the efficiency of delivery of odoriferous substances.

In the patent US 5476660 described compositions intended for application of the active component, such as a fragrant substance on the surface of a target, such as a fabric containing particles of the medium with a cationic surface containing positively charged organic hydrocarbon group, and an active component, absorbed or adsorbed on the particles of the medium. The particles of the medium they are applied on a solid material, such as particles of porous silica, zeolite or latex, polymer with positively charged side groups. Another way of obtaining particles of the medium is the inoculation of one or more polymers, including bifunctional hydrocarbon organic groups on the solid material surface with reactive groups.

In the patent US 6020302 described composition intended for the care of colored things containing polymer with Polyamin the th chain, modified by quaternization, substitution or oxidation, and optionally a fragrant substance, protected by materials of the carrier, such as zeolite, starch, cyclodextrin or wax. In the patent there is no information about the intensity of the aroma of fabrics treated with such compositions.

It is established that the efficiency of the delivery system of odoriferous substances, including particles of insoluble carrier, a polymer containing positively charged functional groups, and aromatic substances adsorbed on the surface of the particles or the particles of the medium can be improved with the use of carrier particles containing surface silanol, and grafting on the surface silanol at least one organosilicon compounds containing amino groups. Such delivery systems of odoriferous substances, containing carrier particles with grafted silicone compound with the amine groups, unexpectedly give a more stable fragrance to fabrics treated with compositions containing the delivery system of odoriferous substances, compared with the delivery systems of odoriferous substances, containing unvaccinated particles of the medium.
