Description

Disinfectant

Technical area

The technical field concerns a combined disinfectant used for these purposes, according to PT classes according to ECHA-EU. That is, according to the established groups of disinfectants according to the Regulation on the placing on the market and use of biocidal products, biocidal products are divided into 22 different types grouped into four main areas, of which this product is intended for classes PT-2 and PT-4.

This means that the product is intended for use for disinfecting various surfaces, floors, linings and equipment, e.g. for the brewing, wine, distillery, beverage (soft drinks) industries, as well as the dairy, poultry, meat, canning, freezing, fish, mill-bakery, pharmaceutical and healthcare industries.

Furthermore, the product is intended for treating various surfaces and warehouse spaces - storage of fruit and vegetables, storage of seeds, feed mixtures, etc.

State of the art

Currently, disinfectants based on chlorine, alcohol, etc. are widely used, basically in the entire food industry (eventually, where it is possible in terms of regulations and standards). The content of active chlorine has a negative effect on human health, which causes, for example, irritation of the mucous membranes of the eyes, mouth, skin and respiratory tract. The most serious consequences are - pulmonary edema, toxic pneumonia, etc. In addition to active chlorine, the greatest danger is posed by by-products - the interaction of chlorine with organic substances, which increases the risk of developing diseases and, of course, the reproductive system of the person who is in contact with this chemical more often also suffers.

Another disadvantage is the smell of chlorine. At the same time, another major disadvantage of chlorine is its inability to effectively penetrate biofilm (microorganisms that form the so-called microbial biofilm and are therefore more resistant to toxic substances). The chlorine contained in disinfectants can also cause itchy skin and burning eyes.

Most disinfectants used, for example, in the dairy industry, include sodium hypochlorite, which, however, has other disadvantages: low storage temperature, high corrosiveness, instability of aqueous solutions over time, which significantly reduces shelf life, and high allergenic activity.

The purpose of disinfection is to remove bacteria, viruses and other impurities - organic and mineral substances that form on the surfaces of technical and technological equipment, floors, walls, etc. That is, to destroy residual microorganisms and pollution present on these surfaces. Inadequate or incorrect cleaning or disinfection of equipment surfaces and areas (so-called general disinfection) allows bacteria to remain on the surfaces of the equipment, i.e. to grow and multiply. This results in an increased number of bacteria. Therefore, it is necessary to focus on effective sanitation and disinfection in general of all parts of the equipment and technical equipment in a given operation. That is, sanitation and disinfection of equipment is the best way to achieve not only microbial cleanliness. Because, if the equipment is not cleaned sufficiently, there is an enormous increase in bacteria with subsequent contamination of products - e.g. milk, various types of beverages, meat, vegetables, etc., which pass through the entire production system. Food impurities and especially deposits in the pipes can increase the operating costs of the entire system, e.g. - by reducing the flow rate, supporting the growth of bacteria and algae and at the same time acting as an insulating layer that reduces heat transfer during pipe cleaning, where the concentration of cations and anions is supersaturated. Resistance to various bacteria, viruses and fungi is currently a very big problem in the field of disinfectants. Because it is possible to generally speak of newly emerging very strong (resistant) strains of bacteria, etc. Currently, disinfectants with strong detergent properties are gradually gaining ground.

As already mentioned, this product also contains a detergent component - Propan-2-ol (isopropyl), which has a strong detergent (cleaning) effect and loosens and removes, for example, deposits and limescale.

List of uses of the disinfectant in question, associated with detergent effects:

The field of technology concerns the area of - disinfectant (with detergent effect) used for disinfection of surfaces (PT-2), materials and equipment. Also for disinfection of emptied warehouses of fruit, vegetables, seeds (active substances according to PT classes - 2 and 4, ECHA-EU).

The product is intended, among other things, for disinfection and mild passivation of equipment made of food-grade stainless steel for the brewing, winemaking, distilling, beverage (soft drinks) industries, as well as the dairy, meat, poultry, canning, freezing, fish, and mill-bakery sectors.

PT 2 area preparations - used for the disinfection of surfaces, materials, equipment that are not used for direct contact with food or feed. Areas of use include, but are not limited to, swimming pools, aquariums, bathing water and other waters; air conditioning systems; and walls and floors in private, public and industrial areas and in other areas of industrial activity.

PT 4 preparations for the food industry - preparations used for the disinfection of equipment, containers, utensils, surfaces and pipes related to the production, transport, storage or consumption of food or feed (including drinking water) for humans and animals.

The form of the preparation - a concentrate containing two quaternary ammonium compounds (QAC), cationic surfactants have a positively charged functional group in their polar part and are strongly hydrophilic, with a broad-spectrum effect, both against microbes, viruses, and molds and fungi (bactericidal, virucidal and fungicidal) with an admixture of other substances. At the same time, the preparation acts as a detergent (cleaning agent), which means that in this case there is no need to use a disinfectant separately and a detergent (cleaning agent) separately, but both functions of this preparation are combined.

New quaternary ammonium compounds (QAC) have a wide range of uses, e.g. as surfactants or antistatic agents, etc. Thus, they are used wherever protection of surfaces against microbial infection is necessary and where virucidal, bactericidal and fungicidal protection is required, in the form of a detergent/sanitizing effect (see DDAC with integrated isopropanol).

As for the quaternary ammonium compounds contained in this disinfectant, i.e. DDAC didecyldimethylammonium chloride (DDAC) and dodecyldipropylenetriamine (Triameen Y152D) - this has a significant effect at a given concentration against microorganisms and bacteria, including enveloped viruses, etc. This means that achieving the full viricidal effect is very effective. Didecyldimethylammonium chloride (DDAC) is a quaternary ammonium compound also used as an antiseptic disinfectant and cleaning agent, and this substance causes the formation of intermolecular interactions and the dissociation of lipid bilayers.

Washing and rinsing are phases of sanitary processing of technological equipment, inventory and various technological devices - potable systems, containers (tanks, etc.), which are used to remove various impurities from the surfaces of the equipment, etc., by a physico-chemical process.

Dirt on surfaces and also deposits in the boiler can increase the operating costs of the entire system

• disinfection (PT 2, 3, 4) • preservation (PT 6, 11, 12, 13)

N-(3-Aminopropyl)-N-dodecylpropane-1,3-diamine, CAS No. 2372-82-9 is a highly effective biocidal active ingredient used in a wide range of disinfectants and preservatives. It is highly effective against Gram-positive bacteria, but significantly less effective against fungi and Gram-negative bacteria in the standard tests EN 1276:2020 and EN 1650:2020.

-8CZ 38468 UI

Triameen® Y12D is also effective against enveloped (lipophilic) viruses. For example, against the H1N1 influenza virus, the EN 14476:2019 test (0.03% protein content) was passed at 300 ppm active ingredient, with a contact time of 10 minutes.

Results of efficacy tests for surface disinfection (conducted by NOURYON, manufacturer of Triameen):

Various standard efficacy tests were performed for surface disinfection with a protein content of 0.03% bovine albumin and a water hardness of 17 °dH.

• EN 1276:2020, bactericidal activity: passed at 0.4% (= 120 ppm active substance) for all 4 test organisms • EN 1650:2020, yeasticidal activity: passed at 0.3% (= 90 ppm active substance) for Candida albicans • ΕΝ 13697:2023 (Surface test without mechanical action for bactericidal and yeasticidal activity): passed for all 5 test organisms at - 1.5% (= 450 ppm active substance) when 0.03% bovine albumin was used as protein load for Pseuomonas aeruginosa (new method) - 2% (600 ppm active substance) when 0.85% skimmed milk was used as protein load for Pseudomonas aeruginosa (old method).

Although Triameen® Y12D is highly soluble in water, after dilution it must first overcome the so-called gel phase. Dilution of Triameen® Y12D requires vigorous stirring and heating to prevent gel formation, which can otherwise lead to uneven distribution of the active ingredient in the formulations. For those customers who have difficulty implementing such conditions in their own production, we recommend using the pre-diluted 30% preparation Triameen® Y12D-30.

Many active ingredients for preservation have strong limitations on their applicability due to their hazard classification as sensitizer, mutagen or carcinogen. Triameen® Y12D has none of these properties. It is also free of aldehydes and halogens. Another limitation of many active ingredients is their suitability as preservatives for EU Ecolabel products.

Many substances have a stated concentration limit that is below the level of effectiveness. There is no stated limit for Triameen® Y12D. It is largely of natural origin with a natural plant-based component, resulting in a 67% Renewable Carbon Index (RCI). Triameen® Y12 will soon be available in an RSPO certified version (a product that is sustainably sourced and meets strict environmental criteria).

Citric acid, monohydrate: (E 330, CAS: 5949-29-1)

1. Citric acid (a biodegradable, weak organic acid) biocidal substance:

-9CZ 38468 UI deposits, rust, mold, mildew and streaks from brass and copper. Uses citric acid as an eco-friendly cleaner.

2. Citric acid - Passivating agent (stainless steel corrosion inhibitor):

The chelation mechanism of citric acid is one of the primary mechanisms by which citric acid hydrate works. This is the ability to act as a chelating agent. Chelation is the process by which a substance forms multiple bonds with a single metal ion. The multiple carboxyl and hydroxyl groups of citric acid allow it to form stable complexes with metal ions. This chemical passivation treats stainless steel equipment to regenerate the protective passive oxide layer (in our case, the acid forms a protective film, thereby achieving a mild antioxidant effect). Citric acid binds very well to metal atoms/minerals in a chemical reaction known as chelation (a physicochemical process in which organic compounds bind to metal cations. Rapid and complete application of passivation protection to these surfaces restores the surface's corrosion resistance, increases the surface's lifespan, and preserves its original appearance.

2.1. Effect of surface damage on materials for stainless steel processing (passivation agent):

After installation and operation of stainless steel equipment, the passive layer of stainless steel can be damaged or removed by physical abrasion or chemical reactions. The passive layer can also be weakened by physical damage due to expansion and contraction caused by heating and cooling. If this damage occurs faster than the passive layer can naturally heal itself, rusting will occur. Citric acid passivation offers a safer and more environmentally friendly alternative to nitric acid passivation. Citric acid is an organic acid and as such is safe for employees. Citric acid fumes are non-toxic and do not harm the air. The term “passive” refers to steel that is now non-reactive, which is very beneficial for equipment used in the food, beverage, dairy, pharmaceutical and cosmetic industries.

Examples of implementing a technical solution

It is a so-called disinfectant concentrate, which is then diluted with water in a given ratio and is then ready for use on surfaces, areas and for mild passivation of stainless steel equipment (Citric acid), etc.

Before use, the product is diluted with water in a ratio of 1:100 (for example: 10 liters of product - per 1000 liters of water) and then ready for use for the purpose of disinfection and sanitation (cleaning) of food systems and other equipment, for so-called general cleaning - sanitation/disinfection by applying to surfaces, areas and rinsing of operating equipment, including slight passivation of equipment, or fogging.

2. Furthermore, the product is intended for the treatment of warehouse spaces and surfaces:

- storage of fruits and vegetables (use when warehouses are empty)

- storage of seeds, feed mixtures, etc. (use when warehouses are empty)

3. The product is also intended for removing dirt, deposits and biofilms:

3.1. Food impurities and especially deposits in the pipes can increase the operating costs of the entire pipe system, for example: by reducing the flow rate of milk, supporting the growth of bacteria and algae, which are removed by didecyldimethylammonium chloride and Citric acid (citric acid) - for disinfecting various pipe systems and jets of hydro-massage baths in healthcare and balneological operations (the product also has an algicidal effect - killing algae, it is also fungicidal, phytopathogenic, i.e. on - fungi, bacteria and at the same time has a detergent - cleaning effect, loosens deposits and limescale.

3.2. A biofilm is usually defined as a loose matrix of many types of microorganisms - bacteria, fungi, algae, yeasts and protozoa - that is held together by a slimy substance called extracellular polysaccharide (EPS). Biofilms form in moist and especially aqueous environments where free-floating bacteria settle and then adhere to surfaces.

Once sessile, bacteria begin to develop a complex three-dimensional community that enhances the survival of individual organisms in the community through their coexistence. Biofilms form on a wide variety of surfaces, piping systems, including metals, plastics, etc.

4. Mild passivating agent - also used to treat stainless steel as a chelating agent:

Chemical passivation treats stainless steel equipment to regenerate a protective passive oxide layer (the layer improves the functional properties of the underlying alloy). Citric acid binds very well to metal atoms, in a chemical reaction known as chelation - a physicochemical process in which organic compounds bind to metal cations.

The rapid and complete application of passivation protection to these surfaces restores the corrosion resistance of stainless steel, increases the life of the surface and preserves its original appearance.

The term “passive” refers to stainless steel that is now non-reactive, which is very beneficial for equipment used in the processing of food, beverages, dairy products, pharmaceuticals and cosmetics.

Citric acid also kills bacteria, mold and fungi, making it suitable for general disinfection and cleaning.

5. Cationic surfactants contained in didecyldimethylammonium chloride (DDAC) and Triameen (DDTA), have a positively charged functional group in their polar part and are strongly hydrophilic.

They have the ability to form electrostatic bonds with negatively charged proteins, which leads to the adhesion of the surfactant to the surface, with a broad-spectrum effect, both against microbes, viruses, and fungi and molds (bactericidal, virucidal, fungicidal, algicidal) with the addition of other substances.

6. The disinfectant/sanitizer and mild passivator is strong enough to fight non-enveloped viruses, including noroviruses, polioviruses, rotaviruses, adenovirus type 2, etc.

At the same time, it also offers a broad-spectrum solution for demanding cleaning tasks - it acts as a detergent (cleaning agent), which means that in this case there is no need to use a disinfectant separately and a detergent (cleaning agent) separately for sanitizing equipment, with both functions of this product being combined, including the function of mild passivation.

- 14 CZ 38468 UI

The product is also suitable for treating walls, ceilings, floors and other parts of spaces intended for storage, for example, and thus ensures the possibility of long-term storage, for example, in warehouses of fruit, vegetables, potatoes, etc. It can also be disinfected - crates, boxes, tools, instruments and other aids.

Since this disinfection/sanitation is effective against bacteria, viruses, fungi and spores, this disinfection can also be used for spaces and areas - veterinary hygiene, hospitals, social services, as well as, for example, in laboratories and the food industry and other fields, including epidemic situations. For use against mold on walls, it is very suitable for effective disinfection of, for example, showers and wellness facilities.
