The technical field to which the invention relates.
The invention relates to a molded solid detergent compositions for cleaning hard surfaces, for washing fabrics or for personal hygiene and, more specifically, to compositions having improved strength and, thus, retains shape even after prolonged contact with water.
The level of technology
Detergent compositions for washing textiles or clean solid surfaces, typically include surfactants, whose role is to remove dirt. Washing textiles or clean solid surfaces of surfactants often consist mainly of nemylnya surface-active substances.
Solid detergent compositions are considerably cheaper than the liquid, due to the low cost of the package and they are very popular forms in developing countries. The solid dosage product easier, this eliminates splashing and application of the product can be better adjusted. Among the solid forms of popular and rapidly expanding markets in developing countries is in lump form. Cleansing compositions in the form of pieces from an economic point of view superior to other forms of product, and dispensing from a piece of well regulated.
For lump detergent required p is Jemima physical strength, such that they retain their structural integrity during handling, transport and application. Accordingly, they can also be incorporated in various abrasives, fillers, modifying additives and other ingredients such as coloring, flavoring, preservatives, etc.
Pieces detergent for washing fabrics and cleaning hard surfaces are in continuous contact with water during use and also often during subsequent storage and, therefore, are moist and usually collapse to form a paste. The shape and contours of such chunks is not maintained in a satisfactory condition.
This problem usually tried to solve it by implementing various changes in the composition of the piece. Any attempt otvetit piece, if not properly regulated the composition, can lead to too solid product that will not release a sufficient amount of product to clean. So this is a major obstacle in order to ensure that: a) is not the destruction of the product during application, (b) no loss of product due to the formation of a slurry, and (C) the product is still soft enough to allow the user to have the ability to find the correct amount of product during purification.
At the same time consider the request of the authors 417/Mum/201 describe the direct application of the molded detergent product, having a water resistant coating that can wear off with washing liquid during application. Preferably, the molded detergent product is an extruded piece and contains abrasive, and on the outer surface of the specified piece of detergent applied one or more materials with a permeability coefficient for water

Composition, cured under UV irradiation
According to a preferred embodiment of the present invention, on the outer surface of the specified lump detergent coated with a polymer cured under UV irradiation. In General, methods of curing under the action of UV radiation are the photopolymerization and can be selected from two main categories: 1) free radical polymerization containing functional group of the (meth)acrylic resins and (2) the cationic polymerization of epoxy resins. Both categories are well known and described in the prior art. Containing functional group of the (meth)acrylic resin, as a rule, contain containing functional group of the (meth)acrylic oligomers and monomers in combination with photoinitiators causing the curing under the action of UV radiation. There is a tendency to use the Snov, cationic system cycloaliphatic epoxides and photoinitiator for the formation of a strong acid under the influence of UV radiation. Strong acid causes rapid disclosure of epoxy groups in the monomers with the formation of reactive cationic groups, attacking and revealing the epoxy group in the next monomer. General description of such systems can be found in Radiation Curing in Polymer Science and Technology, Vol.1: Fundamentals in Methods, Edited by J.P.Foussier and J.E.Rabek, Published by Elsevier Applied Science (1993), and in N.S.Allen, M.A.Johnson, P.Oldring (ed.) and M.S.Salim, Chemistry &Technology of UV&EB Curing Formulations for Coatings, Inks &Paints, Vol.2, SITA Technology, London, 1991.

Photoinitiator cationic polymerization may consist of salts one, ferrocene or page, which form a strong acid when exposed to UV radiation. Typical salts are used as initiators, t is Auda hexafluoroantimonate triarylsulfonium and hexaphosphate definality. One such commercially available initiators initiator sold by UCB Chemicals, Inc., called Uvacure™ 1590. It is a mixture of hexaflurophosphate triarylsulfonium with the solvent propylene carbonate, capable of copolymerization.
Typically, epoxy resins and monomers suitable for the production of polymer coatings according to the invention, curable under the action of UV radiation, are organic compounds containing at least one oxiranyl cycle, capable of polymerization by reacting disclosure cycle. Such materials are called General epoxides, include Monomeric and polymeric epoxides, and can be aliphatic, cycloaliphatic, heterocyclic or aromatic compounds or their combinations. They can be liquid or solid substances or mixtures thereof. Suitable epoxy resins are cycloaliphatic epoxy resins, such as resins containing cyclohexanamine groups, such as epoxycyclohexanecarboxylate.

Typical polyfunctional acrylate monomers are diluted reactions is nesposobnye monomers with a molecular weight of from about 170 to about 1000. Specific examples of polyfunctional monomers that can be used in the present invention are trimethylaminuria (TMRCA), pentaerythrityl, pentaerythritoltetranitrate, glyceryltrinitrate, triarylmethylhalogenides, glycerylphosphorylcholine (GPTA), diacrylates ether hexandiol (HDODA), diacrylates ether of triethylene glycol (TEGDA) and/or its alkoxysilane derived, diacrylates broadcast tripropyleneglycol (TPGDA) and/or its alkoxysilane derived, diacrylates ether of neopentyl glycol (NPGDA) and/or its alkoxysilane derived, tetraacetylethylenediamine, dipentaerythritol(three, Tetra, Penta or hexa)acrylate or similar connection. These monomers can be used singly or in combinations of two or more. The preferred composition for coating include polyfunctional acrylates in an amount of from about 10% wt. to about 60 wt.%, moreover, preferably the range from about 20% to about 50%.
Suitable oligomers are acrylic oligomers with the main chain of carbon atoms, which is formed by the polymerization of acrylate and other monomers with ethylene unsaturation. Other suitable oligomers are atilirovanie or metakrilovoy urethane, atilirovanie complex is polyester, acelerando epoxysilane or atilirovanie simple polyester, in which the main chain contains oxygen and nitrogen urethane [-OC(O)NH-], oxygen of ester [-C(O)O-] or oxygen epoxypropyl or simple ether [-O-]. Acrylic oligomers have an average molecular weight of from about 500 to about 10,000, and preferably 500-4000. Acrylic oligomers are typically copolymers Ethylenediamine monomers, such as styrene, glutaric acid, maleic acid, and esters of acrylic acid containing residual acrylic unsaturation capable of photopolymerization. A preferred example epoxyacrylate oligomer, commercially available from UCB Chemicals, Inc., has an average molecular weight of about 500, diluted to 25% TPGDA and sold under the name Ebecryl™ 605. A mixture of the oligomer/monomer gives utverzhdennuyu UV film, which, according to the manufacturer, has a tensile strength tensile ˜95840 kPa (13900 f/d2), elongation at elongation of 7% and a glass transition temperature of 67°C. the oligomer is a fast curing, provides good gloss and excellent resistance.
A preferred example of the oligomer complex poliefirdiakrilata commercially available from UCB Chemicals, Inc., under the name Ebecryl™ 450 and has an average molecular weight of about 1500. It represents the quick curing polyetiological, modified fatty acid, with excellent wettability. The film formed after curing under UV irradiation, as reported by the manufacturer, has a tensile strength tensile ˜29650 kPa (4300 f/d2), elongation at elongation of 4% and a glass transition temperature of 17°C.
A preferred example of the oligomer acrylic resin commercially available from UCB Chemicals, Inc., under the name Ebecryl™ 745. This oligomer diluted to 46% of the monomer, such as TPGDA. The film formed after curing under UV irradiation, as reported by the manufacturer, has a tensile strength tensile ˜13100 kPa (1900 f/d2), elongation at elongation of 52% and a glass transition temperature of 30°C. This film has excellent mechanical properties and superior adhesion to detergent substrates.
Oligomers, which are examples polyurethanecoated oligomers, as a rule, are synthesized by the interaction of a diisocyanate with a complex polyester or easy polyester with terminal hydroxyl groups to form urethane with terminal isocyanate groups. Then acrylates with terminal hydroxy groups enter into interaction with terminal isocyanate groups. Urethaneacrylate oligomers by nature can be aliphatic or aromatic, depending on the choice of diisocyanate. Typically Polym rnie film based on aliphatic urethaneacrylate are more stable and provide more flexibility. In contrast, aromatic urethaneacrylate more rigid and provide chemical resistance. Similarly, the main chain of the polyol plays an important role in determining the rate of curing and the properties utverzhdenii film. The elasticity of the polymer film, for example, is a function of molecular weight and functionality of the polyol, and higher molecular weight diols provides greater elasticity.
One such commercially available aliphatic urethaneacrylate is commercially available EV 244™, UCB Chemicals, Inc.. This oligomer is a 10% solution of monomer, such as HDODA. The film formed after curing under UV irradiation, as reported by the manufacturer, has a tensile strength tensile ˜25510 kPa (3700 f/d2), and elongation at tensile 60%.
In the composition for coating use, the initiator of photopolymerization to create the possibility of forming curing the above coating film of the polymer components of the composition. The preferred amount in the resin composition for coating is 2-10 wt.%. polymeric composition, and preferably 4-8 wt.%. If the content of the photopolymerization initiator of the less than 2%, the curing of the coating film under the action of UV radiation would be inadequate, and is not pre is respectful content, exceeding 10 wt.%, as will decrease the resistance of a coating film, and the cured coating can be painted.
Suitable free radical initiators for the photopolymerization are compounds of the type of acetophenone, connection type benzoic ether, compounds of the benzophenone type, connection type, phosphine oxide, organic peroxides and similar compounds. Specific examples of such compounds are:
i) carbonyl compounds such as benzoin, benzoylmethylene ether, antinational ether, benzonitrile ether, acetoin, butirosin, tawain, benzil, benzophenone, p-methoxybenzophenone, diethoxyacetophenone, α,α-dimethoxy-α-phenylacetophenone, methylphenylglycidate, ethyleneglycol, 4,4'-bis(dimethylamino)benzophenone. 2-hydroxy-2-methyl-1-phenylpropane-1-it, 1-hydroxycyclohexane;
ii) sulfur compounds, such as tetramethylthiuramdisulphide, tetramethylthiuramdisulphide;
iii) compounds, such as azobisisobutyronitrile and 2,2'-azobis(2,4-dimethylvaleronitrile);
iv) peroxides, such as benzoyl peroxide, di-tert-butylperoxide.
In order to promote rapid curing under the action of UV radiation, typically use synergists mono - or difunctional amines in combination with photoinitiators, such as alkyl/arylketones, or D. the natives initiators type compounds, chip off the hydrogen. Synergists calironia amines promotirovat hardening by formation of free radicals, but also by overcoming the inhibition of polymerization by oxygen on the surface of the coating. In the latter case, aminoacyl interacts with free oxygen, reducing the amount of oxygen available on the coating surface to break polymerization. Not only depleted the oxygen, but also formed another free radical Amin. In the hardened films such calironia amines become part of the cured polymer. Commercially available accelerandi amines are Ebecryl™ R and Ebecryl™ 7100, which sells UCB Chemicals, Inc..
Polymer composition for coating may also contain other conventional additives. For example, it may contain a polymer or silicone additives for improving surface properties, additives that improve the fluidity, dyes, pigments, antioxidants, matting additives (for example, silica with a waxy coating or without it or other inorganic materials), etc. In more preferred embodiments additive to improve fluidity, include at the level of about 0.3-3%, and in one particularly preferred composition include improving the fluidity additive Tego 2100, available from Goldschmidt, Germany.
The polymer composition also in the cancel, optional, suitable inert solvent. Typical solvents are esters, such as ethyl acetate, butyl acetate; ketones, such as acetone, methyl isobutyl ketone and methyl ethyl ketone; alcohols, for example, butyl alcohol; and aromatic solvents such as toluene and xylene. The number of included solvent will vary in accordance with the specific method of application at work. For example, in the case of spray application, typically, will include a larger amount of solvent, while for application with a roller will be used less solvent, if it will ever be used. In any case, the inert solvent will comprise from 0 wt.%. to about 95% wt. the whole composition for coating, and in the preferred compositions for coating 20-80%, more preferred 40 to 60%.
Accordingly, and in another embodiment, the invention relates to a method of obtaining a lump of detergent according to the invention, incorporating the following stages:
(a) forming detergent compositions with obtaining pieces detergent
(b) applying to pieces coating : resin, cured under the action of light,

The formation of pieces of detergent can be accomplished in any Izv the STN in the technique of the method of obtaining a solid molded detergent products such as extrusion, pressing the scroll machine for soap or casting. The first method is usually used for obtaining pieces of detergent for washing clothes and pieces of detergent for cleaning hard surfaces, in particular pieces to work in the dishwasher. The second and third methods are usually used for obtaining pieces of detergent, such as bars of soap for personal hygiene.
With regard to the application of the resin composition for coating, then it can apply the usual method of coating known in the prior art. The method of applying the polymer composition of the present invention is not limited, and usually you can use well-known methods of coating, such as coating using a brush device, coating spray drenching, coating by immersion or dipping, and coating, spraying, or any other way to get a lot of small droplets of resin and allowing them to settle on the surfaces of the piece of detergent with the formation of a smooth film. When coated, preferably using an organic solvent, to find the viscosity of the resin composition for coating from the viewpoint of improving job opportunities, smoothness and uniformity of a coating film and adhesion utverzhdenii pokr the main film to the weight of the piece. Examples of preferred organic solvents are given above, and to such solvents include ethanol, isopropanol, butanol, toluene, xylene, acetone, methyl ethyl ketone, ethyl acetate, butyl acetate and the like solvents. The composition can be applied directly to the surface of the piece or apply to other pre-cured (for example, paints or primers) or wet (for example, in the case of the adhesive layer coating film. The material is advantageously used when the thickness of utverzhdenii film from about 5 microns to 100 microns, with the preferred thickness utverzhdenii film 20-50 μm. The preferred thickness will provide sufficient uniformity of the film without formation of flows and promote a satisfactory cure.

In this regard, the irradiation continues until completion of curing, and preferred exposure time is typically less than 10 seconds. The preferred source of ultraviolet radiation with a wavelength interval from about 180 nm to 450 nm. For example, you can use sunlight, mercury lamps, arc lamps, xenon lamps, gallium lamps and the such sources, but mercury lamps, medium pressure, high pressure or ultra high pressure provide particularly advantageous for fast drying. Preferred mercury lamp medium to high pressure with an intensity of approximately 28 W/cm (70 watts/inch) up to 395 watts/cm (1000 watts/inch). Such preferred methods of curing provide full curing and ensure a suitable coating, resistant to premature yellowing and showing the desired resistance to cracking.
The coating is applied on at least one side of the piece of detergent, preferably at a few parties. However, it is preferable that one side of the piece remained for the most part without coating. Most preferably, the side that remains uncoated, is the side opposite the side on which the piece can easily be put on a flat surface.
The composition according to the invention contains the active detergents, which can be soap or nemalymi surface-active substances and, as a rule, are selected among anionic, nonionic, cationogenic and zwitterionic/amphoteric surfactants or mixtures thereof.
