Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] the application requires the right of priority of No. 11/479,679, the U.S. Patent application submitted on June 30th, 2006, and its content is attached to herein by reference.
Background of invention
[0002] know the consumer's goods in the art, fabric nursing articles for use, personal-care supplies and family articles for use of keeping a public place clean for example, they contain usually gives the consumer's goods and/or handles or one or more essence of the matrix fragrance of coating with the consumer's goods; But these essence in the consumer's goods or the matrix are passed disappearance in time.Another problem of essence is that they discharged before optimal release time in the consumer's goods, and the user of the consumer's goods can't experience the fragrance of essence.For example, need essence to be present in for a long time, and there is the trend of evaporation in time or diffusion in the essence in the clothing at the clothing of using after washing composition and/or fabric emulsifying agent are handled.
[0003] therefore, existing make minimum and make essence discharge the trial of fragrance the best because of essence loss due to volatility and the evaporation.A kind of such method is that essence is encapsulated in the shell, makes fragrance microcapsule.
[0004] be known in the art the theoretical log P (Clog P) of multiple essence, can be at for example Daylight Chemical Information Systems, Inc. (Daylight CIS) Irvine finds in Ponoma 92 databases that CA obtains.The also method of known calculations Clog P in the art.The bigger essence high volatility of the comparable Clog P of essence value that Clog P value is less, therefore water-soluble height is preferred for the consumer's goods.But when the less material of encapsulation ClogP, their leach or be diffused into the trend that shell enters the consumer's goods outward may strong (hindering the best of fragrance to discharge), and essence may finally be diffused into outside the consumer's goods before the human consumer uses.
[0005] developed the method that the essence that prevents in the fragrance microcapsule leaches.These methods can comprise one or more polymer-coated on shell inside or shell outside, or stablizer is mixed in the core.But there is continuous demand in the system that exploitation is discharged fragrance.The essence of more effective release system or more stable encapsulation can cause more effectively using essence, thereby reduces preparation cost.
[0006] contains solvent and/or tensio-active agent for example during the consumer's goods of shampoo when fragrance microcapsule is mixed, may produce stability problem.Packed essence may ooze out outside the shell.Shell also may absorb solvent, tensio-active agent or any other material in the consumer's goods, causes the integrity of shell impaired.Because other diffuse is in shell or core, shell also may expand, or because core material is diffused into outside the shell, shell also may shrink.Really, shell component even can be diffused in the consumer's goods.
[0007] similarly considers to be applied to use other material for example in the release of the micro-capsule of flavouring agent or antimicrobial substance that provides benefit for the human consumer.
[0008] therefore, need the development group compound, said composition is applicable in the composition that stability is provided for the micro-capsule that encapsulates fragrance or antimicrobial material and uses.
The invention summary
[0009] in one embodiment, the invention provides composition, said composition contains:
A. micro-capsule, this micro-capsule contain the shell that the average Clog P of encapsulation is at least about 2.5 material, and greater than the Clog P of 60% (weight) material be at least 3.3 and
