Description
The cross reference of related application
The application requires the right of priority and the rights and interests of the U.S. Provisional Application 60/645,596 of submission on January 24th, 2005, by reference its full content is added this paper at this.
Technical field
The present invention relates to perfume delivery system (perfume delivery system), it comprises having with the organosilane grafting and have the insoluble carrier granule of amino surface silicon alkanol; The polymkeric substance that has positive charge functional group; And spices, described spices is adsorbed on the described carrier granule or absorbs in the described carrier granule.Described perfume delivery system is given the fabric long lasting fragrance with the compositions-treated that contains described perfume delivery system.
Background technology
Fabric care product such as washing composition or fabric softener often contain spices.Described spices not only is used to shelter fabric that the stink beastly and giving of some components of fabric care product handled by fabric care product with pleasant fragrance.
Spices is one of the most expensive composition of fabric care product, therefore wishes to be included in as much as possible being retained in the fabric of handling with fabric care product of spices in the fabric care product.For the fabric care product that is used for handling in water base process fabric, this point particularly important is for example in laundry detergent or rinse cycle fabric softener.For these products, need on fiber, there be perfume delivery system, this means that perfume delivery system will adhere to fiber in fabric treating, can not run off with washing lotion or rinsing liquid.The delay that this perfume delivery system should also provide spices discharges, and with long lasting fragrance, flavour intensity can not feel to have unhappiness the appropriate level during beginning with the fabric of giving processing.
GB 1306924 discloses finely divided silicon-dioxide and the finely divided silica gel carrier granule as spice oil.Use these carrier granules, liquid perfume oil can be mixed with the free-pouring powder that comprises the spice oil that is not higher than 70 weight %.
US 5,840, and 668 disclose the laundry detergent powders that contains spices.Disclosed washing composition contains and is comprising that soft silica is as the spices on the carrier system of carrier.Walk on the 7th hurdle the 58th the 26th row record of the 9th hurdle experiment confirm the spices that is adsorbed on the carrier particles of silica only be discharged in the water lotion apace in the presence of the low quantity of surfactant.Therefore, this perfume delivery system can not be transported to spices on the fabric of handling with disclosed washing composition effectively.
US 4,954, and 285 disclose the silica dioxide granule that will be adsorbed with spices on it is added in the solid drier activatory fabric softener composition.The document walks to the 55th row and discloses the silica dioxide granule that contains spices and can discharge spices during in the use fluid wets on the 4th hurdle the 53rd.According to its instruction, the document discloses the particle of the fabric softener composition that comprises the silica dioxide granule that contains spices, and for this fabric softener is used for water base process, it has extra water-insoluble coating.
US 4,954, and 285 disclose a kind of spices, and it comprises by the particle of montmorillonite type clay or contains the carrier that the zeolite that absorbs the spices in the particle constitutes, and has the preferably textile binding agent coating of quaternary ammonium compound.This perfume delivery system is used for laundry detergent, and the document discloses and contained spices but do not have the fabric of the laundry detergent washing of carrier system to compare, with the fabric fragrance level increase of this laundry detergent washing.Yet US 4,536, and its shortcoming of disclosed perfume delivery system is in 315, and in the process of handling fabric, tensio-active agent or dispersion agent are easy to remove the particulate coating, and this can reduce spices and carry effect.
US 5,476, and 660 disclose the composition that is used on target surface such as fabric deposition active substance such as spices, its comprise have cationic surface, the carrier granule of positively charged organic carbyl and the suppressed by vector particle absorbs or the active substance of absorption.Can be by making carrier granule with the polymer-coated solid material with the positively charged group of side chain such as porous silica, zeolite or latex particle.The another kind of method of making carrier granule is to make solid material with surface reaction group and one or more contain the polymer graft of organic carbyl of two functional groups.
US 6,020, and 302 disclose the color care composition, and it comprises polymkeric substance and the optional spices with solid support material such as zeolite, starch, cyclodextrin or wax protection that exists with polyamine backbone of modification via quaternized, replacement or oxidation.The document is not instructed the perfume intensity with the fabric of described compositions-treated.
Have been found that now and comprise insoluble carrier granule, have the polymkeric substance of positive charge functional group and be adsorbed to or the perfume delivery system that adsorbs the spices of described carrier granule into can have the carrier of surface silicon alkanol and has the amino described surface silicon alkanol of organosilane grafting and improve with at least a by use.Compare with comprising not the perfume delivery system of grafted carrier granule described comprising with the perfume delivery system that has amino organosilane grafted carrier granule, unexpectedly gives to and more long lasting fragrance stronger with the fabric of the compositions-treated that comprises described perfume delivery system.
