Description

The invention relates to the field of sanitation and hygiene, namely to disinfectant detergents and can be used as a composition of a sanitary detergent for a chemical dry toilet, ensuring the decomposition of organic waste, for filling the upper and lower tanks of the dry closet in order to ensure high-quality flushing, washing its body , as well as disinfection, deodorization of the contents of the upper and lower tanks, and ensuring the recycling of waste collected in the lower tank of the dry closet.

A dry closet is an autonomous device, for the operation of which there is no need to connect a sewerage system or other communications, so modern dry closets can be used almost anywhere where there are no appropriate amenities, for example, in a country house.

Liquid composting toilets usually consist of two parts. On top there is a toilet and a container for flushing fluid (upper tank), and below there is a container for collecting and recycling waste (lower tank).

Liquid chemical toilets use special chemicals to break down waste.

Typically, the upper tank is filled with water or a waste flushing solution. These compositions provide deodorization of water in the upper tank and improve the procedure for removing the contents of the toilet bowl, and also disinfect the toilet bowl. The lower tank is filled with compounds that decompose human waste, ensuring recycling and neutralization of waste.

Liquids for dry toilets based on microorganisms (biological preparations), as well as based on a mixture of chemicals, are widely known from the prior art. However, the advantages of using chemical substances in biotoilets for waste processing over biological preparations based on microorganisms is the ability of chemicals to work effectively at almost any temperature, including winter, while the temperature range for the vital activity of living bacteria is limited and amounts to +4 - ( +30) degrees. In this regard, it is not recommended to use biological products in winter or under conditions of sudden temperature changes. In addition, biological products cannot be combined with chemicals, that is, when filling the lower tank of a dry closet with a biological product, you cannot use antiseptics and deodorants in the upper tank, since beneficial microorganisms die upon contact with these substances.

Also known from the prior art is a large number of chemical-based liquids for dry closets of different compositions. However, they also have some disadvantages.

In particular, known bottom tank liquids do not provide a high rate of breakdown of biological waste.

Some compositions for the lower tank of a dry closet contain components (for example, ammonium preparations) that cannot effectively process dry closet waste if they contain household chemicals or detergent components, which limits their use in conjunction with liquids for the upper tank of a dry closet intended, in including for cleaning and disinfecting the toilet bowl of a dry closet.

In addition, many liquids for the bottom tank of composting toilets contain aggressive chemicals to ensure effective waste recycling. These are liquids for dry toilets, for example, based on chlorine, as well as containing salts of phosphoric acid and phosphonates. The use of such liquids over time can lead to damage to the plastic casing or destruction of rubber or metal casing elements (for example, seals) of the dry closet. And the need for periodic cleaning of the dry closet, that is, additional mechanical impact (for example, with a brush) on the body and body elements of the dry closet significantly increases the risk of damage to them, which leads to a decrease in the service life of the dry closet.

In addition, liquids for the lower tank of a toilet often contain formaldehyde as a decomposition agent, which is a very toxic substance, which does not allow the liquid for a dry closet to be considered environmentally friendly and which creates problems with the disposal of recycled waste, since recycled waste cannot be discharged into the environment.

For example, a liquid for the care of toilet cabins, Goodhim Bio-T Prof, is known from the prior art in the form of a concentrate, intended for conservation, disinfection and deodorization, rapid decomposition of waste (prior to subsequent disposal) of the contents of mobile and autonomous toilet cabins, dry closets, country toilets , cesspools and garbage containers (https://www.bafus.ru/100149900/). The specified liquid contains in its composition, %: aromatic composition - less than 5%, dye - less than 5%, active detergent surfactant component - 5 - 15%, QAC (quaternary ammonium compound) - 15-30%, water - from 30% and more. The disadvantage of the known liquid is the insufficiently high rate of decomposition of waste from the lower tank of the dry closet, due to the ingress of detergents included in the liquid for the upper tank, which excludes the possibility of using this liquid in the lower tank, as well as using this liquid simultaneously for the upper and lower tanks of the dry closet.

The technical problem to be solved by the claimed invention is the development of a universal composition of a sanitary detergent for a dry closet, ensuring the decomposition of organic waste, and performing the functions of both a liquid for the upper and lower tanks of a dry closet, while maintaining operating efficiency over a wide temperature range .

The technical result achieved by implementing the claimed invention is the expansion of functional characteristics due to the possibility of using the developed composition for both the upper and lower tanks of a dry closet, increasing the efficiency of cleaning the toilet bowl of a dry closet from various types of contaminants, improving the flushing of waste, as well as a significant increase in speed splitting organic waste from dry closets while maintaining the environmental friendliness of the composition.

Composition for a dry toilet containing Neonol AF 9-10, and/or Neonol AF 9-9, and/or Neonol AF9-12, Katamine AB, Bioneutral C5 or Katon LXE, fragrance, dye, water in the following ratio, wt.%:

Neonol AF 9-10 and/or Neonol AF 9-9, and/or Neonol AF 9-12 - 8.5 - 10.0;

Katamin AB - 38.0 - 45.0;

Bioneutral C5 or Katon LXE - 0.05;

Fragrance - 0.2 - 0.4;

Dye - 0.1 - 0.3;

water - the rest.

The finished product is a liquid, the color and smell of which is determined by the choice of dye color, as well as fragrance, and is characterized by high consumer properties (high detergency, cleaning ability and high speed and efficiency of breakdown of organic waste from the dry closet), due to the optimal qualitative and quantitative composition.

Bioneutral C5 or Kathon LXE is a biocidal preparation based on a mixture of active components: 5-chloro-2-methyl-4-isothiazolin-3-one, 2-methyl-4-isothiazolin-3-one, present in a ratio of 1 :1, and stabilizers based on magnesium chloride and nitrate, activators.

Katamine AB is a disinfectant and biocide, belongs to cationic surfactants and is a quaternary ammonium salt - a mixture of alkyldimethylbenzylammonium chlorides, where alkyl is a mixture of normal alkyl radicals C10-C18 or C12-C14.

Neonol AF 9-10 is an ethoxylated monoalkylphenol based on propylene trimers and is a highly effective nonionic surfactant (formula C9H19C6H4O(C2H4O)10H).

Neonol AF 9-12 is also an oxyethylated monoalkylphenol, while the version of Neonol AF 9-10 differs from Neonol AF 9-12 in that the number of moles of ethylene oxide combined with the alkyl radical is 10, not 12. Accordingly, Neonol AF 9-9 contains the number of moles of ethylene oxide combined with an alkyl radical equal to 9.

As a result of the research, the optimal component and quantitative composition of the detergent was established. It has been shown that the combination of Neonol AF 9-10 and/or Neonol AF 9-9, and/or Neonol AF 9-12, Katamina AB, Bioneutral C5 or Katon LXE in a specific quantitative ratio allows achieving a synergistic effect in the resulting composition, which provides the composition good consumer properties: high washing (cleaning) and decomposing ability, which makes it possible to achieve complete removal of contaminants from the toilet bowl of the dry closet with each flush, eliminate the formation of plaque on the toilet bowl, and also significantly increase the efficiency and rate of decomposition of organic waste of the dry closet.

The inventive composition of a sanitary detergent is obtained by mechanical mixing of the components. The components of the product are available and are produced by industry in a form (liquid) suitable for the technological process. To prepare the composition, water heated to 40°C was loaded into the mixer and Neonol AF 9-10 (or Neonol AF 9-9, or Neonol AF 9-12, or a mixture thereof) and Katamine AB were added while stirring, after which stirring was carried out until complete dissolution of the components (within 20-25 minutes). Next, Bioneutral C5 or Katon LXE, fragrance and yellow dye were loaded into the solution, after which stirring was carried out for 10-15 minutes.

Thus, in the process of work, a series of samples of sanitary detergent compositions with different ratios of components were developed and studied. Table 1 shows examples of the compositions of 16 samples.

At the same time, examples 1-6 disclose the compositions of the composition according to the claimed solution, and examples 7-16 are given for comparison and disclose compositions that differ in the ratio of the components of the product from the claimed solution.

We also conducted a study of a commercial product - liquid for the care of toilet cabins (in the form of a concentrate) Goodhim Bio-T Prof, characterized by the following composition: aromatic composition - less than 5%, dye - less than 5%, active detergent surfactant component - 5 - 15%, HOUR 15% - 30%, water -30% or more. The specified product was accepted as an analogue.

A comparison of the consumer properties of the prepared compositions and the analogue was carried out on the basis of the obtained indicators of washing and decomposition abilities (Table 2).

The consumer properties of the resulting compositions (washing (cleaning) and decomposition abilities) were determined as follows.

The composition was poured into the upper or lower, or simultaneously into the upper and lower tanks of the ECOS OC07 chemical dry closet, the volume of the lower and upper tanks being 10 and 12 liters, respectively. The consumption of the composition is as follows: 50 ml of the composition for every 10 liters of tank volume. Thus, 50 ml of the composition and 10 liters of fresh water were added to the upper tank, and 50 ml to the lower tank. composition and 2 liters of fresh water. Next, the dry closet was operated for 30 days under the most approximate conditions (number of users), after which the contamination of the toilet bowl of the dry closet (indicator of washing (cleaning) ability), the rate and efficiency of decomposition of organic waste of the dry closet (indicator of decomposition capacity) were assessed. The rate of decomposition of organic waste from the dry closet was assessed by the frequency of cleaning the bottom tank of the dry closet for 30 days. Cleaning was carried out when the lower tank was filled to 95%. The process of decomposition of organic waste is accompanied by the transformation of sewage into a cloudy, odorless liquid and sediment (silt). At the same time, it is known that as a result of decomposition, the amount of feces decreases several times. Thus, it is obvious that with a high rate of waste decomposition, fewer cleanings of the bottom tank of the dry closet are required. The efficiency of organic waste decomposition was assessed by the appearance of the contents of the bottom tank of the dry closet, while effective decomposition means the presence of only sludge and water in the bottom tank.

Tests have shown that the compositions of the developed composition (patented composition) according to examples 1-6 are characterized by a higher rate and efficiency of decomposition of organic waste, as well as a higher efficiency in cleaning the toilet bowl of a dry closet than the compositions according to examples 7-16 and the like. It was also noted that the compositions of the developed composition (patented composition) according to examples 1, 3, 6 showed unexpectedly maximum speed and efficiency of decomposition of organic waste with high efficiency in cleaning the toilet bowl from plaque and other contaminants.

It is also important to note that the results obtained allow us to conclude that only the simultaneous presence of all three active components in the composition: Neonol AF 9-10 in the stated ratio allows achieving high results (Examples 1-6). Study of compositions with a similar qualitative, but different quantitative composition (Examples 7-16), as well as compositions that do not contain the drug Bioneutral C5 or Caton LXE (but essentially a mixture of 5-chloro-2-methyl-4-isothiazoline-3 -one, 2-methyl-4-isothiazolin-3-one, present in a ratio of 1:1) (Example 17) or a composition containing, instead of the drug Bioneutral C5 or Caton LXE, only one of its active components (Examples 18, 19) - showed that these compositions are characterized by lower consumer properties, which confirms the principle of choosing a certain quantitative and qualitative composition of the composition.

In addition, compositions corresponding to the compositions in Examples 1-6 were also tested, with the only difference that instead of Neonol AF 9-10, Neonol AF 9-9 or Neonol AF 9-12 or a mixture of all three drugs with a 1:1 ratio was used :1. When studying the consumer properties of these compositions (the results are not shown in the table), it was also found that these compositions are characterized by a high level of washing (cleaning) ability and a high rate and efficiency of decomposition of organic waste from the dry closet. The results obtained were comparable to the results obtained when testing the compositions in Examples 1-6, however, nevertheless somewhat lower, which, obviously, was the result of using Neonol AF 9-9 or Neonol AF 9-12 instead of Neonol AF 9-10 or a mixture of all three drugs with a 1:1:1 ratio. Thus, we can conclude that in order to obtain the highest possible cleaning and degrading properties, it is important to use ethoxylated monoalkylphenol in the composition, in which the number of moles of ethylene oxide combined with an alkyl radical is 10, that is, the drug Neonol AF 9-10.

Thus, the developed composition of a sanitary detergent (disclosed in Examples 1-6) is characterized by high cleaning power and high efficiency and speed of processing (splitting, decomposition) of organic waste from dry toilets, with a high environmental friendliness of the composition and disinfecting ability. At the same time, the developed composition is universal and can be used both for filling the upper and lower tanks, as well as simultaneously the upper and lower tanks of the dry closet. Moreover, when the composition is used simultaneously in both the lower and upper tanks of the dry closet, the high efficiency of the liquid in cleaning the toilet bowl of the dry closet and the rate of decomposition of the organic waste of the dry closet are maintained. In addition, the developed composition was tested when operating at ambient temperatures from 0°C to +30°C. It was found that temperature does not have a negative effect on the consumer properties of the composition.

Also, the developed composition does not contain aggressive substances, which eliminates damage to elements made of metal, plastic, rubber and wood and can significantly extend the service life of the dry closet. In addition, the penetration of detergents into the lower tank containing the developed composition does not impair the efficiency of the latter, which allows the use of detergents when cleaning the lower tank.
