The technical FIELD

This invention relates to compositions containing microcapsules flavoring, and their stability in detergent compositions.

Prior art

Agents to create useful effects, such as fragrances, silicones, wax, flavoring agents, vitamins and fabrics softeners are expensive and generally less effective when used in large quantities in the compositions of personal hygiene, cleaning compositions and compositions for the care of fabrics. Consequently, there is a desire to increase the efficiency of these agents to produce useful effects. One way of achieving this goal is increasing the efficiency of delivery and time of the active life of the agent to create useful effects. This can be achieved by creating an agent to create useful effects as a component of the microcapsule.

Microcapsules provide several useful effects. They provide protection agent to create useful effects from physical interactions or chemical reactions with incompatible ingredients in the composition, of a transition in flying condition or evaporation. Microcapsules have an additional advantage, which is that they can deliver the agent to create useful effects to the substrate and can be ashitani on the destruction of desirable conditions, for example, when drying fabric. Microcapsules can be particularly effective for delivery and secure flavors. Microcapsules can deliver and keep the flavors in the tissue, breaking down and distinguishing flavor only after drying of the fabric.

Microcapsules are produced by the application of the agent to create useful effects on water-insoluble porous carrier or by encapsulating agent to create useful effects in water-insoluble shell. In the latter case, microencapsulation particles obtained by precipitation and deposition of polymers on the surface of the partition, for example in koatservatov it is, for example, as disclosed in GB-A-0751600, US-A-3341466 and EP-A-0385534, or other methods of polymerization, such as interfacial polycondensation, US-A-3577515, US-A-2003/0125222, US-A-6020066, W02003/101606, US-A-5066419. Particularly suitable means of encapsulation is the use of the condensation reaction of melamine/urea and formaldehyde, as described in US-A-3516941, US-A-5066419 and US-A-5154842. Such capsules are obtained by first emulsifying agent to create useful effects in small droplets environment precompensate obtained by the reaction of melamine/urea and formaldehyde, and then carrying out the polymerization reaction with deposition on the surface section of the oil-in-water. This incapsulate the basic particles, having dimensions in the range from several micrometers to millimeters, get in suspension in the aquatic environment.

However, the most difficult problem with the incorporation of microcapsules in the composition of detergents is their stability. The flavor over time seeps out of the microcapsules. This is particularly noticeable in those cases where the composition contains a surfactant and a solvent, as it happens in most detergent compositions. The applicant has unexpectedly found a solution to this problem when creating compositions flavoring.

Understood that the term fluid includes viscous or flowable liquids with Newtonian or non-Newtonian rheology and gels. This composition may be Packed in the container or made in the form of a standard dose of the encapsulated material. The latter form is described in more detail below. Liquid compositions are essentially non-aqueous. Under non-aqueous means that the compositions of the present invention contain less than 20% water, preferably from 1 to 15%, most preferably from 1 to 10% of the total water. Under the General water is understood as free and bound water. Compositions used in products in the form of standard doses containing liquid composition contained in a water soluble film, often described as non-aqueous.

Compositions of the present invention, preferably, have a viscosity of 1 to 10,000 centipoise (1-10000 MPa·s), more preferably from 100 to 7000 centipoise (100-7000 MPa·s), and most preferably, from 200 to 1500 centipoise (200-1500 MPa·s) at 20-1and 21°C. the Viscosity can be determined by conventional methods. However, in accordance with the laws the AI with the present invention, the viscosity is measured by using a rheometer AR 550 company TA Instruments using spindle diameter 40 mm steel plate and the gap size of 500 ám.

The microcapsule

The composition according to the present invention includes microcapsules flavoring. The microcapsule preferably includes a core material and a wall material that at least partially surrounds the specified core.

In one aspect, at least 75%, 85% or even 90% of these microcapsules may have a particle size from about 1 micron to about 80 microns, from about 5 microns to 60 microns, from about 10 microns to about 50 microns or even from about 15 microns to about 40 microns. In another aspect, at least 75%, 85% or even 90% of these particles for delivery of the agent, creating a useful effect may have a wall thickness of the particles is from about 60 nm to about 250 nm, from about 80 nm to about 180 nm, or even from about 100 nm to about 160 nm.

In one aspect, the material of the wall of the microcapsules may contain a suitable resin, including the reaction product of the aldehyde and amine, and suitable aldehydes include formaldehyde. Suitable amines include melamine, urea, benzoguanamine, glycoluril and mixtures thereof. Suitable melamine include metropolin methylated metropolin, erinomainen and mixtures thereof. Suitable urea include dimethylamino, the methylated dimethylamino, urea-resorcinol and mixtures thereof. Suitable materials for manufacturing can be floor is received from one or more of the following companies: Solutia Inc. (St Louis, Missouri USA), Cytec Industries (West Paterson, New Jeresy, USA), Sigma-Aldrich (St. Louis, Missouri USA). It was found that it is possible to obtain microcapsules containing melamine-5-formaldehyde aminoplast terpolymer containing polyol as one of the fragments, especially aromatic polyol as one of the fragments.

Thus, provided microcapsules containing a core of fragrance and a shell of ameloblastoma polymer, and the shell comprises 75-100% of a thermoset resin containing 50-90%, preferably 60-85% of terpolymer, and 10-50%, preferably 10-25% of a polymeric stabilizer; terpolymer contains: (a) 20-60%, preferably 30-50% of fragments derived from at least one polyamine, (b) 3-50%, preferably 5-25% of fragments derived from at least one aromatic polyol; and (C), 20-70%, preferably 40-60% of the fragments, wybranych from the group consisting of alkilinity, alkylene fragments containing from 1 to 6 methylene units, preferably from 1 to 4 methylene units, and most preferably, methylene link, dimethoxymethane and dimethoxymethane. By "fragment" is meant a chemical particle, which is part of terpolymer and derived from specific molecules. Examples of suitable poliamidowych fragments include, without limitation, derivatives of urea, melamine, 3-substituted 1,5-diamino-2,4,6-Resina (1.5 to 30 diamino-2,4,6-triazine) and glycoluril (glycouril). Examples of suitable aromatic polyol as one of the fragments include, without limitation, derivatives of phenol, 3,5-dihydroxytoluene, bisphenol a, resorcinol, hydroquinone, Xylenol, polyhydroxyalkane and polyphenols produced during the degradation of cellulose and humic acids.

The use of the term "derived from" does not necessarily mean that the movie terpolymer is directly derived from the substance, although it is possible (and often does). In fact, one of the more convenient ways to get terpolymer includes the use of substituted alkylamine groups (alkylolated) polyamines as starting materials; they unite in a single molecule both (a)and (C) fragments of the above.

Suitable substituted alkylamine groups polyamine comprise a mixture of mono - or polyamidine alkylamine groups of polyamines, which, in turn, can be partially alkylated alcohols containing from 1 to 6 methylene units. Alkylated polyamine, especially suitable for use in the present invention include mono - and polymethylsiloxane precondensed, such as commercially available under the trademark URAC (company Cytec Technology Corp.) and/or partially methylated mono - and Polymetal-1,3,5-triamino-2,4,6-triazine precondensed, such as whom archacki available under the trademark CYMEL (company Cytec Technology Corp.) or LURACOLL (BASF), and/or mono - and polyalkyl-benzoguanamine precondensed, and/or mono - and polyalkyl-glycoluril (glycouril) precondensed. Such substituted alkylamine groups polyamine can be obtained in the form of a partially alkyl forms obtained by attaching short-chain alcohols, typically containing from 1 to 6 methylene units. It is known that such partially alkylated forms are less reactive and therefore more stable during storage. Preferred polyalkyl-polyamines are Polimetall-melamine and Polymetal-1-(3,5-dihydroxybenzyl)for 3,5-triamino-2,4,6-triazine.

Polymer stabilizer may be used to prevent agglomerating microcapsules, speaking, therefore, as a protective colloid. It is added to the mixture of monomers before polymerization, and this leads to its partial retention polymer. Specific examples of suitable polymeric stabilizers include acrylic copolymers carrying sulphonate groups, such as commercially available under the trade name LUPASOL (BASF), for example, LUPASOL PA 140 or LUPASOL VFR; copolymers of acrylamide and acrylic acid, copolymers of alkylacrylate and N-vinylpyrrolidone, such as available under the trademark Luviskol (e.g., LUVISKOL TO 15, 30 or 90 BASF); polycarboxylate sodium (Polyscience Inc.) Ripoli(styrelseledamot) sodium (Polyscience Inc.); copolymers of vinyl and methylvinylether simple ether and maleic anhydride (e.g., AGRIMER™ VEMA™ 'AN, the ISP company), and copolymers of ethylene, isobutylene or styrene and maleic anhydride. Thus, the preferred polymeric stabilizers are anionic polyelectrolytes.

Microcapsules of the type indicated above are made in the form of aqueous suspensions, typically having a solids content of from 20 to 50%, more typically, the solids content of 30 to 45%, where the term "solids content" refers to the total weight of the microcapsules. The suspension may contain technological additives such as hydrocolloids for stabilization and control of viscosity, biocides and additional sinks of formaldehyde.

Typically, hydrocolloids or emulsifiers are used in the process of emulsification of flavor. Such colloids increase the stability of the suspension to coagulation, sedimentation and delamination. The term "hydrocolloid" refers to a large class of water-soluble or water-dispersible polymers, anionic, cationic, zwitterionic or non-ionic character. These hydrocolloids/emulsifiers may contain a fragment selected from the group consisting of carboxy, hydroxyl, thiol, amine, amide, and combinations thereof. Hydrocolloids suitable for use in the present invention, Katya the t: Poliplast, such as starch, modified starch, dextrin, maltodextrin and cellulose derivatives, and their stereoselectivity forms; natural gums such as alginate esters, carrageenan, xanthane, agar-agar, pectin, pectic acid, and natural gums such as gum Arabic, tragacanth gum and gum karaya, guar gum and stereoselectivity guar gum; gelatin, protein hydrolysates and their stereoselectivity forms; synthetic polymers and copolymers, such as poly(vinyl pyrrolidone-co-vinyl acetate), polyvinyl alcohol-co-vinyl acetate), poly((meth)acrylic acid), poly(maleic acid), poly(alkyl(meth)acrylate-co-(meth)acrylic acid), copolymer of polyacrylic acid-co-maleinovoi acid), poly(alkylenes), poly(vinylethylene ether), polyvinyl ether-co-maleic anhydride) and the like, as well as poly(ethylenimine), poly((meth)acrylamide), poly(alkylenes-to-dimethylsiloxane), poly(aminodimethylaniline), etc. and their stereoselectivity form. In one aspect the specified emulsifier may have a pKa value less than 5, preferably more than 0 but less than 5. Emulsifying agents include copolymers of acrylic acid-alkylacrylate, polyacrylic acid, fatty esters polyoxyethylenesorbitan, polyalkylene-to-carboxyanhydride, polyalkylene-co-maleic anhydrides, poly(metilidinovy e is Il-co-maleic anhydride), poly(butadiene-co-maleic anhydride) and poly(vinyl acetate-co-maleic anhydride), polyvinyl alcohols, polyalkylene glycols, polyoxyethyleneglycol and mixtures thereof. Most preferably, the hydrocolloid is a polyacrylic acid or a modified polyacrylic acid. The value of pKa of colloids, preferably, has a value of from 4 to 5, and therefore the capsule has a negative charge when the pH value of the suspension of microcapsules flavoring (PMC) above is 5.0.

The microcapsules preferably have a nominal mass ratio of shell to core below 15%, preferably below 10%, and most preferably below 5%. Thus, the microcapsules may have a very thin and fragile shell. The ratio of the shell and the core is determined by measuring the effective amount of the encapsulated perfume oil in microcapsules, pre-washed with water and the selected filter. It is done by extraction of sediment wet microcapsules method enhanced microwave irradiation, solvent extraction and subsequent gas chromatographic analysis of the extract.

Most preferably, the encapsulated flavoring inside aminoplast capsule, and the capsule shell contains urea-formaldehyde or melamine-formaldehyde polymer. More preferably, e is lokapala additionally has a coating or partial coating of a second polymer, containing a polymer or copolymer of one or more anhydrides (such as maleic anhydride or a copolymer of ethylene/maleic anhydride).

The microcapsules of the present invention can be positively or negatively charged. However, preferably, the microcapsules of the present invention are negatively charged and have a Zeta-potential ranging from minus 0.1 MeV -100 MeV, when the dispersion in deionized water. "Zeta-potential (ζ) denotes the apparent electrostatic potential generated by any electrically charged objects in solution, measured by special methods. A detailed description of theoretical basis and practical significance of Zeta-potential see, e.g., in the book "Colloid Science: Zeta Potential in Colloid science: Principles and Applications" (Hunter Robert J.; Editor.; Publisher (Academic Press, London); 1981; p. 1988). The Zeta-potential of the measured object at a certain distance from the surface of the object and it is usually not the same, and has a lower value than the electrostatic potential on the surface.

However, its value is the appropriate measure of an object's ability to engage in electrostatic interactions with other objects present in the solution, especially with molecules with multiple binding sites. Zeta-potential is a relative measure and its value depends is it from the method of its measurement. In this case, the Zeta-potential of the particles is measured by the so-called method of phase analysis of scattered light by using a Malvern instrument Zetasizer (Malvern Zetasizer 3000; Malvern Instruments Ltd, Worcestershire UK, WR14 1XZ). The Zeta-potential of a given object may also depend on the number of ions present in the solution. The magnitude of the Zeta potential indicated in this application is measured in deionized water, in which there are only counterions charged microcapsules. More preferably, the microcapsules of the present invention have a Zeta-potential is equal to -10 -80 MeV to MeV, and most preferably from -20 -75 MeV to MeV.
