RO120650B1 - Concentrated detergent for ceramic surfaces - Google Patents

Abstract

The invention relates to a concentrated detergent for the ceramic surfaces in the bathrooms or in public buildings, consisting of 10...19% natural C12-C14 fatty coconut alcohols, ethoxylated with 3 moles of ethylene oxide and propoxylated with 2 moles of propylene oxide, 3...7% natural coconut fatty alcohols, ethoxylated with 9 moles of ethylene oxide, 15...25% citric acid, 0.1...1% curing agent, 0.01...01% dye and 0.5...1% perfume.

Description

The invention relates to a concentrated detergent for ceramic surfaces such as floors, walls in bathrooms, showers, toilets, as well as for ceramic surfaces existing in public buildings or industrial premises.

Cleaning is the process of physical removal of dirt adhered to surfaces by mechanical adhesion, van der Waals forces or electrostatic adhesion. This process can be a physico-chemical reaction by reaction between detergent and dirt, or a physical one only, by solvating or emulsifying the particles of dirt. During the cleaning process, the residues being removed, the environment of microorganism development also disappears. At the same time, most bacteria are removed, in the proportion of 90 ... 99.9%. depending on their type.

Washing hard surfaces can be done manually or automatically. The detergent compositions for washing hard surfaces must be formulated so as to take into account factors such as: the type of dirt, the degree of cleaning required, the cleaning equipment, the sensitivity of the substrate to the chemical attack of the ingredients.

A liquid detergent intended for hard surfaces should have a washing effect so that, upon clearing, it will allow water to drain from the washed surface in the form of a continuous film.

A liquid, concentrated, environmentally friendly and biodegradable detergent is known for hard surfaces, consisting of polyethylene glycols with an average molecular weight of 200 to 4000 and / or their mixture, stabilized and purified and a non-ionic surface agent (RO 116100), but which it has the disadvantage that it involves the use of purified products.

Also known is a disinfectant-detergent composition, used as a sanitizing agent, consisting of sodium or potassium hypochlorite, alkaline hydroxide, water-soluble polycarboxylic acids, phosphoric acid salts, detergent, sodium carbonate, triethanolamine and water (RO 11). ), but which has the disadvantage of a small scope.

The technical problem that the invention solves is to determine the detergent components and their proportions, so as to ensure multiple effects of cleaning and disinfection, maintenance and biodegradability.

The concentrated detergent, for ceramic surfaces, according to the invention, removes the disadvantages mentioned in that it consists of 10 ... 19%, preferably 11 ... 14%. nonionic surfactant, selected from natural coconut fatty alcohols, C ₁₂ -C ₁₄ ethoxylates with 3 moles of ethylene oxide and propoxylates with 2 moles of propylene oxide, 3 ... 7%, preferably

4 ... 6% ethoxylated natural coconut fatty alcohols with 9 moles ethylene oxide, 15 ... 25%. preferably 18 ... 22%. citric acid, 0.1 ... 1%, preferably 0.2 ... 0.4%. preservative, 0.01 ... 0.1%. preferably 0.06 ... 0.08%. dye, 0.5 ... 1%, preferably 0.7 ... 0.9%, perfume composition and 30 ... 65% water.

The concentrated detergent is in the form of an aqueous solution.

The detergent according to the invention has the following advantages:

- can be easily obtained from easily accessible components;

- it is a concentrated product and thus reduces transport and labor costs;

- working solutions with low concentrations are obtained by simply diluting with water;

- it is effective on a large number of deposits;

- does not attack the surfaces, being compatible with the usual materials of their manufacture.

The following is an example of an embodiment of the invention.

In a reaction vessel equipped with a stirring system, 60 L of water is charged, then gradually add, under stirring, 12 kg of natural coconut fatty acids, C ₁₂ -C ₁₄ ethoxylates with 3 moles of ethylene oxide and propoxylated with 2 moles of propylene oxide, 4 kg of C ₁₂ -C ₁₄ ethoxylated fatty alcohols

RO 120650 Β1 with 9 moles of ethylene oxide, 20 kg citric acid, 0.2 kg perfume, 0.4 kg preservative 0.008 kg 1 colorant. If the product is clear, gradually add the rest of the water (5.4 l) and leave it to mix for about 15 minutes while stirring. If it is cloudy or has 3 separation tendencies, it is used to clear isopropyl alcohol, introduced gradually, as

I, within the limit of 6%, percentage of mass, of the quantity of product. The product obtained is packaged 5.

The product is diluted with water in a first step, in a proportion of 3/1 and used 7 as such. Apply to the cleaning surface, leave for a few minutes for action, then rinse the surface with water. For walls, it is further diluted, in a second step, 9 in proportions of 0.5 ... 5% in water. The application can be done with the mop or with mechanical means of washing, rinsing and vacuuming. 11
