Definitions

• the subject of the invention relates to a cleaning product, which is fluid with a low viscosity value in the concentrated state so that it may be pumped and which acquires a viscous form upon the increase of its viscosity when diluted to thereby provide effective cleaning.
• Hygiene is one of the primary factors influencing the human health. Therefore, it is a necessity to provide the ideal hygiene conditions in the bathrooms and toilet rooms in the public spaces and private spaces where the people are present in order to meet their basic needs.
• the ideal hygiene conditions are achieved by way of effective cleaning of the bathrooms and toilet rooms following their use.
• Today, the cleaning of said spaces is performed with the cleaning means that require manual use and/or with the cleaning products that contain the chemicals with various properties.
• the frequency of the cleaning to be performed, the cleaning performance expected from the product, the storage conditions for the product, and the product densities and viscosities affecting these conditions are of significance for the choice of the cleaning products to be employed in the spaces requiring continuous cleaning.
• the non-concentrated viscous cleaning products i.e. the products having a high viscosity value, or the concentrated low-thickness cleaning products, i.e. the products having a low viscosity value
• the non-concentrated high-volume disinfectants containing a small quantity of active disinfectant enable each cleaning process to be realized using a small quantity of disinfectant in the spaces that require continuous cleaning.
• the thickening materials (the agents that increase viscosity) are added to the non-concentrated cleaning products in order to prevent the product from flowing off the surface to be cleaned without performing an effective cleaning.
• the nonconcentrated cleaning products with high viscosity are obtained, which are able to adhere for a longer time on the surfaces to be cleaned to thereby enable the surfaces to be cleaned more effectively and which at the same time enable the use of a small quantity of active ingredient during each cleaning process.
• Said cleaning products adhere for a longer time on the surfaces to be cleaned and thus, enable a more effective and thorough cleaning for the entire surface by using a small quantity of active ingredient.
• some facilities such as hotels requiring continuous industrial cleaning lack the storage areas with sufficient size to store the high- volume cleaning products such as diluted disinfectants.
• the concentrated non-viscose toilet cleaning products diluted at 10% are commercially available.
• viscosity is one of the properties of a fluid cleaning product that affects the cleaning performance.
• the concentrated products used according to the state of the art despite containing a high quantity of cleaning agent and/or anti-limescale agent, are not able to adhere on the surface for a time sufficient to ensure effective cleaning as they lack the viscosity required to provide effective cleaning and are not able to provide a cleaning as effective as that provided by the viscous products as they rapidly flow off the inner surface of the toilet during the use.
• the concentrated cleaning products developed with the purpose of meeting said need are obtained by way of dissolving the active ingredients in a low quantity of solvent and are easy to store owing to their small volume.
• the cleaning performance of the cleaning product increases with increasing concentration of the active disinfectant in the cleaning product; however, this at the same time increases the cost of the product and the toxic and corrosive effects on the living beings. While the use of a product containing a high quantity of disinfectant in the spaces that require frequent cleaning provides ease of storage, they are required to be diluted during the use as they adversely impact the human health. Further, the product is required to have an ideal viscosity to enable the same to adhere on the surface to achieve effective cleaning.
• a toilet cleaning product has been developed wherein said cleaning product has its viscosity increased and becomes viscous when diluted so that it can provide more effective cleaning and is in liquid form when in concentrated state so that it can be pumped.
• the cleaning product according to the invention When in the concentrated state, the cleaning product according to the invention is in fluid form of low viscosity so that it can be pumped.
• the product Upon being diluted, the product acquires thickness and its viscosity increases.
• the cleaning product according to the invention is preferably used byway of being diluted at 5%. Accordingly, the product is also advantageous in that it enables a reduction in the storage area in addition to providing effective cleaning.
• the cleaning product according to the invention Owing to the cleaning product according to the invention becoming viscous when diluted, it displays high cleaning performance and achieves effective cleaning by successfully adhering during the use on the surfaces to be cleaned. Owing to the product's being supplied and stored in concentrated state and used by way of dilution, the useful life of the product is prolonged as compared to the non-concentrated products used in the state of the art. This enables greater quantities of disinfectant-containing products to be stored in a storage area and accordingly, the products to become depleted after longer time periods. It is further aimed to supply the desired quantity of products by a smaller number of shipments and hence provide contribution to the less fuel consumption, the control of the greenhouse gases and the sustainability.
• An object of the invention is to develop a cleaning product, which is fluid and concentrated so that it can be easily pumped, is supplied and stored in this state and thus eliminates the need for greater storage areas and enables greater quantity of active disinfectants to be stored in the currently available storage areas.
• Another object of the invention is to develop a cleaning product, which is able to be brought into viscous form by way of dilution prior to use, thereby reducing the adverse effects of the disinfectants on the human health and environmental health as well as providing an effective cleaning by adhering on the surfaces to be cleaned.

• the lime test was conducted on the marble cubes.
• the solution SI when in the diluted state remained insufficient in removing the limescale. Due to the significant corrosive effect of hydrochloric acid, it was not considered appropriate to increase the acidity by way of increasing the ratio of hydrochloric acid in the solution.
• the ratios of the acid compounds contained in the solution S2-S3 turned out inadequate and thus, the antilimescale performances of these solutions remained low. Because citric acid and formic acid are weak acids, it was considered appropriate to prefer stronger acids as the acid compounds and accordingly, to prepare the solutions comprising stronger acids as the acid compounds, for obtaining the cleaning products used in the industrial areas.
• the anti-limescale performances of the solutions S4-S7 prepared by the use of phosphoric acid as the acid with anti-limescale characteristic were considered sufficient and consequently, phosphoric acid was chosen as the acid compound to be used in the cleaning products to be prepared.
• the surfactants enable the surface tension of the cleaning product to be reduced and thus enable the same to better spread over the surface and effectively clean the uneven surfaces in particular. Accordingly, the surfactants selected from C9-C11 oxo alcohol ethoxylates, oleylamine alcohol ethoxylates, C16-18 and C18 unsaturated ethoxylate mixtures and isotridecanol ethoxylate may be used as the surfactant in the cleaning products. Said surfactants are able to reduce the surface tension; however, they fall short in enabling the cleaning product to be fluid when in the concentrated state and/or to become viscous upon being diluted. For this reason, it is necessary to use within the scope of the invention the surfactants that will not provide thickness to the cleaning product in a highly acidic medium but will be able to provide thickness in a less acidic medium as the acidity will decrease when the product is diluted.
• At least one surfactant was determined, said surfactant enabling the cleaning product to be fluid when in concentrated state, while enabling the same to become viscous when diluted preferably at a ratio of 5-8%.
• at least one surfactant selected from a hydrotrope compound or amines, C12-16-alkyldimethyl, N-oxides or amines, C12-18-alkyldimethyl, N-oxides or 2- hydroxyethyl amine oxide compounds was used as the surfactant.
