The present invention relates to an aqueous composition comprising hydrogen peroxide and its use for cleaning surfaces.
Cleaning or dezinfitciruushsie compositions containing hydrogen peroxide, are well known. Thus, in U.S. Patent No. 5349083 described aqueous composition containing lower aliphatic, nagkalat (e.g., peracetic acid) and produced by combinations of hydrogen peroxide and a lower aliphatic acid.
In WO 99/28427 describes whitening aqueous composition comprising hydrogen peroxide, a polymeric thickener, additives, stabilizing the rheological properties and alkaline buffer agent. The pH value of the compositions disclosed in the examples, is at least 7.
The method of cleaning roofs using aqueous cleaning compositions containing peroxide, known from Patent Application Australia No. 2002100596. This document discloses a method of cleaning the roof, which includes the following stages: (i) drawing on the lower part of the roof of an effective amount of a neutralizing means, (ii) the application to the roof aqueous compositions containing detergent, (iii) washing with water the specified files from the roof, in which wash water flows from the roof towards neutralizing means, so that the remaining detergent was kind of balanced out. Described detergent is predstavlyaet a hydrogen peroxide, percarbonate, prior percarbonate acid, prsilikat, persulfates, perborates, organic and inorganic peroxides and/or hydroperoxides. Washing composition also contains a surfactant.
It was found that such detergent compositions can be improved by the addition of active thickener. Active thickener is a polymer thickener capable in an acid medium in the presence of hydrogen peroxide to form a peroxide group (for example, group nakilat).
The pH value of the aqueous compositions according to the present invention is 3 or less, and the composition according to the present invention includes the following ingredients (based on the total weight of the composition):
a) 0.05 to 40% (mass.) polymeric thickener containing-OOR group, where R is independently selected from H, HE, and carbon-containing group,
b) 0.05 to 60% (mass.) hydrogen peroxide
where the content of active oxygen provided by the ingredient (a)is at least 0.02 percent (based on the total weight of the composition) provided that the (co)polymers derived from (meth)acrylate monomers are missing.
The aqueous composition according to the present invention includes an active agent containing a peroxide group and having the washing ability. The advantage of an active agent with whom is he remains active for a longer period of time and is more effective, in particular, on the surface to be treated, in comparison with standard nagkakamali. The relatively low value of pH of the aqueous composition allows the composition to remain stable during storage, i.e. leads to a reduction in the loss of activity over time. The storage stability is particularly increased if the water composition, in particular a polymeric thickener, essentially, does not contain impurities, such as compounds of transition metals, such as copper, cobalt, iron, etc. If such transition metals are present, to ensure the stability of the composition to the aqueous composition may be added connections, linking metal ion in the chelate complex. In addition, the lower pH values, more stable functional group nagkalat combined with the specified spot stabilizer.
In one embodiment of the invention the pH value of the aqueous composition is 3 or less, and the composition comprises the following ingredients (based on the total weight of the composition):
a) 0.05 to 20% (mass.) polymeric thickener containing 20-100000 of monomer units and an average of at least 0.8-OOR groups, a monomer where R is independently selected from H, HE, and carbon-containing group,
b) 005-30% (mass.) hydrogen peroxide
C) 0.5 to 60% (mass.) one or more aliphatic carboxylic acids containing from 1 to 8 carbon atoms, their complex alilovic esters, anhydrides, and/or nagkalat,
where the content of active oxygen provided by ingredients (a) and (C)is at least 0.02 percent based on the total weight of the composition.
Due to the presence of a polymeric thickening agent (ingredient a), the washing composition according to the invention is more active against surface cleaning than comparable compositions which do not contain a thickener or contain other thickeners.
Moreover, thickeners reduce the mobility of the composition so that the possible longer periods of its contact with not horizontal surfaces. When cleaning the roof composition according to the present invention the composition before its admission into the environment is deactivated (i.e. has a lower content of active oxygen and a higher pH). Therefore, a separate neutralizing agent, which is used in the above-mentioned Application for Patent Australia, there is no need, and this means that the cleaning composition according to the present invention is more environmentally friendly and allows you to simplify the purification procedure.
The polymeric thickener is present in the composition and according to the invention in a concentration of, equal to at least 0.05% of (mass.), preferably, at least 0,1% (mass.), more preferably, at least 0.2 percent (mass.). The maximum concentration of 20% (mass.), preferably 10% (mass.), more preferably of 2.5% (mass.) (all percentages are given based on the total weight of the composition). Specialist in the art will understand that the concentration of the polymeric thickener in the composition also depends on the molecular weight of thickener: when a higher molecular weight, the preferred lower concentration.
Polymeric thickening agent usually contains at least 20 Monomeric units, preferably the thickener contains 20-100000, more preferably 100-75000, even more preferably 200-50000 of monomer units.
In one embodiment of the invention the polymeric thickening agent contains an average of at least 0.6-COOR groups, a monomer, preferably at least 0.7 and-COOR groups, a monomer, most preferably at least 0,8-COOR groups, a monomer where R is independently selected from H, HE or carbon-containing group. In other words, the thickener contains carboxylic acid (R=H), nakilat (R= OH) and/or ester (R=group containing a carbon atom). Group containing a carbon atom, may be any Deputy containing p is at least one carbon atom. Usually a group containing a carbon atom, selected from the group comprising alkyl, acyl and aryl.
At least in part-COOR groups present in the Deputy, R is a HE that speaks about the formation of functional groups nagkalat. It should be noted that the-COOR group can be present in the polymeric thickener already before adding it to the aqueous composition, that is, before contact with hydrogen peroxide, or they may be formed after contact with hydrogen peroxide.
In this description, the term "Monomeric link" does not apply to duplicate the link, but refers to the basic Monomeric unit. For example, xanthan gum duplicate link is pentamer of five pyranose rings. However, the monomer units are separate pyranose ring. As another example, Monomeric units of carboxymethyl cellulose (CMC) are individual glucose units. In the context of the present invention, the expression "R is independently selected" means that for each individual-COOR groups in a polymeric thickener R is selected independently.
The polymeric thickener may be any polymeric thickener containing-COOR groups, which can form a peroxide group. In addition, the content of active oxygen in peroxidebased polymeric thickener which leaves at least 0,02% (mass.) based on the total weight of the composition. The authors of the present invention found that xanthan gum contains 0,6-COOR groups, a monomer, but does not form peroxide groups in the number corresponding to the present invention. Examples of suitable polymeric thickeners are Homo-, co - and terpolymer carboxylic acids, functionalized cellulose functionalized and/or cross-linked carboxymethylcellulose, polyacrylates, polymethacrylates, functionalized polystyrene (SMA polymers), alpha-methylthiopyrimidine acids, functionalized, EHEC, polyvinyl alcohol (PVA), PVP and functionalized polyolefins and/or halogenated polyolefins.
Synthetic polymers obtained through polymerization, in particular (co)polymers derived from (meth)acrylate monomers, are less preferred because they are usually more difficult to biological decomposition method and more burdensome for the environment. Such synthetic polymers are also expensive. In addition, peroxidizable acrylate (co)polymers have a tendency to stand out and/or deposited from aqueous composition.
In one embodiment of the invention the polymeric thickener selected from ethers of cellulose, starch and polyesters. Examples of such polymer zagustiteleyj carboxymethylcellulose (CMC) and carboximetilkrahmal.
We have also studied the application of a combination of two or more of the above polymeric thickeners.
In yet another embodiment of the invention, such compositions thickeners may contain other inert thickeners to facilitate adjusting the viscosity without any adverse effect on the cleaning ability of the composition.
The pH value of the composition is 3 or less, preferably is in the range from 1 to 3.

The maximum number of such third ingredient is 60% (mass.), preferably 55% (mass.), most preferably 50% (mass.) based on the total weight of the composition.
In this description, the term "aliphatic carboxylic acid" refers to carboxylic acids in which the carboxylic acid group (i.e.- COOR group) is not attached directly to the aromatic ring. Although aromatic carboxylic acids, i.e. acids that contain a fragment of a carboxylic acid, directly attached to the aromatic ring (as benzoic acid or dipicolinic acid) can be present in compositions according to the invention as an additive, it is important that the composition includes at least a 0.5% (mass.) aliphatic carboxylic acid containing from 1 to 8 carbon atoms, the corresponding complex Olkiluoto ester, anhydride and/or nagkalat.
