CZ403792A3 - Cleansing agent and process for producing thereof - Google Patents

Abstract

A cleaning agent contains from 6 to 8 percent by weight of diethyleneglycol, 9 to 11 percent by weight of tenside, 3 to 5 percent of triethanol-amine and/or diethanoleamine, 27 to 33 percent by weight of ethylenediaminetetraacetic acid salt, 0.3 to 0.5 percent by weight of formaldehyde, 1 to 2 percent by weight of spirit, 1.5 to 2.5 % by weight of fragrance, and water. One portion of water, which is heated to 30 - 40 degrees Celsius, is added with ethylenediaminetetraacetic acid salt and thus obtained mixture is cooled down to 12 - 18 degrees Celsius, preferably to 15 degrees Celsius, whilst diethyleneglycol, tenside, diethanolamine and/or triethanolamine are gradually added thereto. Formaldehyde is added to the second part of water. The fragrance is added to an aqueous mixture of spirit. Thus prepared mixture is subjected at 10 - 20 degrees Celsius to ultrasound with 9 - 11 Hz frequency during 30 - 60 min and consequently the mixture is exposed to the light with 500 - 100,000 lux intensity.

Description

The invention relates to the composition of the cleaning composition as a mixture of substances and to a process for its preparation.

BACKGROUND OF THE INVENTION

Current cleaning agents are categorized according to the type of cleaning material for commercial purposes. For example, textile and carpet cleaners consist of anionic and non-ionic surfactants, soap, phosphates, silicates, dirt binding agents and salt. Other more progressive formulations include borates, sulfate, soda, dyes, copolymers and strength regulators. For ceramics and enamelled metal sheets, surfactants with natural ingredients such as fine quartz sand or marble flour are an essential component. The fragrance component is further added to the substances thus prepared. Alcoholic preparations are another group of cleaning products.

The disadvantage of current formulations is the necessity of their heat preparation, especially when applied to textile materials.

SUMMARY OF THE INVENTION

The essence of the detergent solution lies in its composition and preparation method. The composition consists of 6-8% by weight of diethylene glycol, 9-11% by weight of a surfactant selected from oxoethylene and oxopropylene fatty alcohol, polyethylene oxide and a copolymer of ethylene oxide with propylene oxide, 3-5% by weight of a substituted amine selected from triethanolamine and diethanolamine, 27-33% % by weight of tetrasodium ethylenediaminetetraacetic acid, 0.12 to 0.5% by weight of formaldehyde, 1 to 2% by weight of ethanol, up to 1.5 to 2.5% by weight of the fragrance component and the remainder to 100% by weight of water.

The process according to the invention is characterized in that to a part of the corresponding quantity of water at a temperature of 30 to 40 [deg.] C. the tetrasodium ethylenediaminotetraacetic acid salt is first added and the resulting mixture is cooled to 15 to 20 [deg.] C. the surfactant, di- and / or triethanolamine and to the rest of the water formaldehyde and to the aqueous ethanol solution the fragrance component and the thus prepared mixture are subjected to ultrasound at a frequency of 9 to 11 Hz for 30 to 60 min. and then irradiated with light of 500 to 100,000 lux.

In this way, better and easier mixing of the components of the mixture is achieved without sedimentation.

The quality requirements according to PND 25-203-81 type B for the diethylene glycol used are as follows: external appearance - colorless transparent liquid without impurities and mechanical impurities, ethylene glycol content max. 0.8% by weight, triethylene glycol content max. 1.5% by weight, acidity calculated as acetic acid max. 0.005% by weight, water content max. 0.2% by weight, color in units Handball max. 20, ash content max. 0.005% by weight

The requirements for triethanolamine and diethanolamine properties are as follows: - light yellow to yellow viscous liquid, highly hygroscopic with a slight ammonia odor, density at 20 ° C min. 1120 kg / m3, water content - max. 0.5% by weight, equivalent molar mass - min 140, alkalinity in mg KOH / g max.400, diethanolamine content - max. 20% wt, triethanolamine content - min. 80% wt.

Ethylenediaminotetraacetic acid tetrasodium salt may be added in the form of a cleaning product under the trade name Syntron B containing 75% of the active ingredient of the tetrasodium ethylenediaminotetraacetic acid salt. Its alkalinity, expressed as Na ₂ CO _3, is at most 4% and at most 5% by weight of moisture.

hydrophilic

Alternatively, a surfactant such as Slovanik 3070/7, which is a non-ionic surfactant, and wherein the polypropylene glycol chain forms a hydrophobic moiety and a polyethylene glycol moiety, may be used as a surfactant. Slovanik is a viscous liquid with a min. 70% Soluble in water. The cloud point is above 100 ° C. Toxicity DL50 = 7.3 g / kg.

Quality indicator: appearance at 20 ° C - viscous yellow liquid, water content - max. 30% by weight, active substance content min. 70% by weight, density at 20 ° C in kg / m3 - 1070 to 1099, solubility of 10% solution - clear, pH of aqueous solution

6.5 to 8.5.

The aqueous concentration of the detergent composition in the water when applied may be about 50%, the solution thus prepared having a pH of 7-8.5. When disposed of, there is no increase in the pH of the waste water and its discharge therefore does not contradict the sewage regulations and applicable regulations. At this concentration, the cleaning agent is particularly suitable for machine cleaning. In addition to the following advantages of absence of toxicity and irritability, its other advantage is its excellent degreasing capacity and high efficiency in removing even hard-to-remove substances such as blood, eggs, carbohydrates and the like.

Acute oral toxicity and skin irritation tests were performed to determine the potential toxicity of the cleanser. Four types of FA, tangerine, galemia and lemon were also tested.

Acute oral toxicity:

male rats: oral LDO 10.000 mg / kg body weight, 24 hours, female rats: LDO 10.000 mg / kg body weight, 24 hours.

Acute oral LDO i.e. the mean lethal dose could not be determined. No animal died after a dose of 10,000 mg / kg.

Animals used: Wistar SPF / specific pathogen free male rats 170-190 g, female 160-180 g, VELAZ PRAHA.

Acute dermal toxicity:

male rats: dermal LDD 5,000 mg / kg body weight, 24 hours, female rats: dermal LDD 5,000 mg / kg body weight, 24 hours.

The value of acute dermal LDD could not be determined. After a dose of 5,000 mg / kg per cut skin. no animal died in the back under wrap for 24 hours. Higher doses cannot be administered.

Animals used: Wistar SPF rats male and female weighing 200 g, VELAZ PRAHA.

Primary skin irritation:

A group of experimental rats with an initial weight of 180 g received 250 g of undiluted test products a total of 5 times daily. Repeated administration did not induce irritation at the application site. Degree of irritation: 0

Overall rating:

Test product of the cleaning composition according to the invention using 4 types of fragrance based on the values of acute oral and dermal toxicity in accordance with the valid regulations of the Ministries of Health and Justice, implementing the Act No. 206/88 Coll. poisons and certain other substances harmful to health shall not qualify as poison. According to the 1979 European Community Categorization of Hazardous Substances, it is a non-toxic substance. The product does not irritate the skin after repeated applications. The methodology 401, 402, 404, OECD was used for testing

Guideline for Chemicals, ED OECD 1987. Tests were carried out to maintain the GLP criteria.
