The technical FIELD

The present invention relates to liquid compositions containing microcapsules, and these microcapsules include a resin containing formaldehyde, and formaldehyde scavenger with the rapid kinetics of the reaction. More preferably, the absorber is a formaldehyde scavenger based on sulfur. The composition preferably further comprises at least one additional formaldehyde scavenger is present in the premix suspension of microcapsules, which is added in the liquid composition of the finished product. Specified additional formaldehyde scavenger to be added in the composition of the suspension can be a material based on sulfur, but preferably, is not material on the basis of sulfur.

Prior art

Have positive influence agents 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 for personal care, detergent compositions and compositions for the care of fabrics. Consequently, there is a need to maximize the effectiveness of such agents that have beneficial effects. One way to achieve this is to increase the effektivnosti delivery and increasing the period of activity of the agent, have beneficial effects. This can be achieved through the use of agent that have beneficial effects, as a component of the microcapsules.

Microcapsules are made by applying the agent, which have a beneficial effect on water-insoluble porous carrier or by encapsulating agent, which have a beneficial effect, water-insoluble shell. In the latter category microencapsulation materials produced by deposition and deposition of polymers on the surface of the partition, such as in the koatservatov it is, for example, as disclosed in GB-A-0751600, US-A-3341466 and EP-A-0385534, or using other methods of polymerization, such as interfacial polycondensation, US-A-3577515, US-A-2003/0125222, US-A-6020066, W02003/101606, US-A-5066419. A particularly suitable method of encapsulation is the use of the condensation reaction of melamine/urea - formaldehyde, as described in US-A-3516941, US-A-5066419 and US-A-5154842. Such capsules are obtained by first emulsifying agent, which have a beneficial effect in small droplets in the environment precompensate obtained by the reaction of melamine/urea and formaldehyde, and then create the conditions for reaction polymerisation deposition on the surface section of the oil-in-water. After receiving the encapsulated materials with sizes from n the number of micrometers to millimeters in the form of a suspension in an aqueous environment.

Microcapsules provide several useful effects. They have a useful effect protection agent, which have a beneficial effect on the physical or chemical reactions with incompatible ingredients of the composition, volatilization or evaporation. Microcapsules have an additional advantage, which is that they can be delivered to the substrate agent, which have a beneficial effect, and can be made so that they exploded in the desired conditions, for example after drying fabric. Microcapsules can be particularly effective in the delivery and security of flavors. Flavoring agents can be delivered into the tissue and held in it by using the microcapsules are destroyed and release as a consequence, the flavor only when the fabric dries.

Preferred microcapsules are architecture core-in-shell and includes a shell made of a resin containing formaldehyde. Applicants have discovered, however, that when such microcapsules are introduced into the composition, regardless of the content of the core of the microcapsules, the composition containing the microcapsules, changes color. Particularly problematic is the change in the color blue product on the green. This is particularly problematic in cases where the product is Packed in transparent the first or translucent container. The change of color, apparently, depends on the level of content of the microcapsules and the storage temperature. Higher storage temperatures and/or higher concentration of microcapsules cause the product to lose color quickly and with great depth of color.

Without limitation by theory it is believed that sulfur absorber prevents discoloration of the product due to rapid reaction with formaldehyde present in the product (see graph below). Reaction kinetics of absorption of impurities, as is, depends on a number of factors, including: low-molecular absorbers are more mobile in the reaction with formaldehyde; a simple binding reaction admixture runs faster than a complex multi-stage reaction, the solubility of the absorber in the water because the absorber must be in the same phase, and formaldehyde. Materials that react with formaldehyde with the same or greater rate also prevent discoloration in the same way.

Test method for absorption of formaldehyde:

Evaluation of the kinetics of binding of formaldehyde scavenger is carried out by quantitative definition of the Oia, the resulting reaction product. % completion of reaction is defined as a measured quantity of the reaction product divided by the maximum number of the reaction product, which can be established theoretically (assuming that all the formaldehyde is associated absorber).

Kinetic experiments carried out in commercially available buffer at pH 8 (Merck n° 1.09460, on the basis of a mixture of boric acid/sodium hydroxide/hydrogen chloride) at 21°C. this buffer was added to 0.2% wt. formaldehyde and 2 × theoretical content of the absorber required to bind all of formaldehyde (taking full binding of formaldehyde), and mix. For example, to determine the kinetics of the reaction of formaldehyde and potassium sulfite, 1:1 molar reaction of 2.1% wt. the potassium sulfite was added to 0.2% wt. of formaldehyde. The yield of the reaction between formaldehyde and the absorber in the liquid mixture is measured directly by the method of mass spectrometry. For the purposes of the experiments of the present invention, the applicants used a mass spectrometer API3000 (Sciex Applied Biosystems) with three quadrupole lenses. The mass spectrometer is configured to control the reaction product of the sulfite/formaldehyde 1/1 (hydroxymethanesulfinic acid) and the reaction product acetoacetamide/formaldehyde 2/1 (2,4-diacetylpyridine) in time. The measurements are carried out in accordance with the provider manual.
