Abstract
The present invention relates to a composite storage technique for perfume essence. The perfume particle is made up by using perfume microcapsule and beta-cyclodextrin for compounding perfume or its water-soluble derivative, bonding them with nonylphenol polyethenoxy ether and coating with modified starch. The liquor core of the perfume microcapsule is formed from rigid support containing phenylethylene or methyl methacrylate. The perfume particle disclosed by said invention can make perfume not easy to volatile and can storage for long time, and in the course of washing, it can effectively control diffusion of fragrance, and make washed clothings retain fragrance durably.
Description
The present invention relates to the compound storing technology of essence and flavoring agent industry, its product is a perfume particle.
As everyone knows, it is quite difficult when fabric washing spices being passed to fabric.Tensio-active agent and other alkaline washing auxiliary agents in the foul, bring very big difficulty also for the spices attachment fabric on removing fabric, and particularly those volatility and unsettled spices are difficult to keep fabric fragrance in rinsing and drying process.In addition, because washing composition generally is alkalescence, Chinese national standard (GB13171-91) regulation I, II class washing powder pH value are less than 10.5, III class washing powder pH value is less than 11, and in this alkaline environment, the spices that contains aldehyde, ester group is unsettled, be easy to decompose, volatilize, be difficult to preserve.Particularly in China, because the washing machine popularity rate is not high, manual prewashing (scrubbing) is more general, and an urgent demand provides a kind of spices consumption few, and the shelf time is long, the persistent washing powder perfuming of washing back lasting technology.
The method of handling fabric with microcapsule and cyclodextrin is known, by literature search, find relevant patent number piece: " perfume microcapsules that is used for granular detergent compositions " (CN1044295A), " perfume particle of covering " (CN1054264A), " microcapsule aromatizing agent and preparation method thereof and purposes " (CN1073711A), these textile treatments formerly, what all adopt is simple essence micro-capsule or essence sorbent material, in a single day in washing process, be subjected to the external force extruding, friction, during shearing, brittle shell is squeezed broken, inner essence distributes rapidly, and fabric is through rinsing, dry back fragrance is lost already and is made a gift of to the greatest extent.Therefore, although above-mentioned disclosure is arranged, the perfume particle of the washing methods of hand-washing and machine-washing appears taking into account yet, with meeting the market requirement.
The purpose of this invention is to provide a kind of spices composite particles that is used for granulated detergent, product can be preserved more for a long time, and simultaneously it can have the release fragrance of control in washing process, again can be after fabric washing lasting 3～5 days.
For solving above-mentioned task, the present invention reaches according to following principle and technical scheme: in view of spices can be compound with beta-cyclodextrin monomer or derivative soluble in water, employing has the perfume microcapsule of rigid support, make it in washing, drying process, keep granular, the fragrance that comprises is come out by slowly-releasing; Adopt beta-cyclodextrin or derivative soluble in water absorption spices simultaneously, make that it dissolves, desorb in washing process, disengage fragrance.The perfume particle that the present invention relates to, it is characterized in that: the beta-cyclodextrin of perfume microcapsule, banana aldehyde or derivative soluble in water, bonding through polyoxyethylene nonylphenol ether, the weight ratio that its component cooperates is a perfume microcapsule 1: beta-cyclodextrin or derivative 1～4 soluble in water: polyoxyethylene nonylphenol ether 0.2～1.0.For granularity and detergent particles are complementary, select the modified starch coating for use.During the fusion coating, the weight ratio of modified starch and perfume microcapsule is 7～15 times.The liquid core of perfume microcapsule is for adsorbing vinylbenzene or the methyl methacrylate or the formed polymkeric substance of the two mixture of spices, and the adsorptive capacity of spices is 2～10 times of polymer weight, is preferably 4～7 times.The shell of microcapsule is by control reaction temperature and stirring velocity, carry out crosslinked back and the water-insoluble hard brittle material that forms constitutes by gelatin gum arabic condensation product and suitable aldehyde or other gelatin hardening agents, microcapsule through mean particle size behind the fluidised bed drying between 30～300 μ m, be preferably 80～220 μ m, particle is too small to be difficult for being deposited on the clothing, excessively then easily discovered by naked eyes, microcapsule shell is thick to be 5～50 μ m, is preferably 20～30 μ m.
The used beta-cyclodextrin derivative of the present invention comprises cyclodextrin carbonates, ethers, or the cyclodextrin derivative that replaced by functional group of one or more hydroxyl, these functional groups comprise: methyl, ethyl, hydroxyethyl, hydroxypropyl or ether base, and any proportioning of cyclodextrin monomer and its derivative.
The spices that the present invention mentions is meant that odoriferous material maybe can offset the material of unpleasant odor, can be any proportioning.Solid essence must be used earlier with the immiscible organic solvent liquefaction of water back and use.The spices of making microcapsule is meant the material of any water-insoluble (or water-fast substantially).
The perfume particle that the present invention mentions is used for granulated detergent, and its weight ratio accounts for 3～15%, is preferably 5～10%, must contain any at the feasible anion surfactant in washing field in the washing composition.Granulated detergent can also comprise following combination among the present invention: enzyme, bleach-activating agent, anti-dirt be deposition agent, fabric white dyes, short enzymic activity agent, sequestrant, suds suppressor, weighting agent, sterilant, polyoxyethylene glycol (molecular weight is 4000～10,000 ten thousand) again, polyvinylpyrrolidone (molecular weight is 8000～15000).
Perfume particle of the present invention, vinylbenzene after its perfume microcapsule employing polymerization or methyl olefin(e) acid methyl esters or the two mixture are as rigid inner core, compare with the perfume microcapsule of no rigid support, under same experiment condition, through ultraviolet spectral analysis, there is the concentration of perfume of the perfume microcapsule of rigid inner core still to keep 33% of former microcapsule concentration, and the perfume microcapsule that does not have rigid support has only 5%, under Electronic Speculum, observe, the perfume microcapsule of 90% tool rigid support is structural integrity still, and the perfume microcapsule that does not have a rigid support has only 25% to keep structural integrity.Because there is the kernel of microcapsule to stop, the fragrance emanation degree is greatly reduced, though fabric through rinsing, dry the back microcapsule and can also major part preserve, thereby reach the lasting effect of lasting.Simultaneously, since to perfume microcapsule and spices compound beta-cyclodextrin through the modified starch embedding, it is not directly contacted with alkaline matter, the loss of spices is greatly reduced, and prevent microcapsule and granulated detergent because of particle difference causes the component segregation too greatly, also can improve the flowability and the anti-sedimentary once more ability of dirt of washing powder in addition.
