Closest to the proposed dishwashing detergent "Afol" according to TU 38.507-63-251-92, having the following suck, wt. Nonionic surfactants 20-30 Urea 4-6 Glycerin 2.0-5.0 Water Up to 100
The purpose of this tool is to clean solid metal and non-metal surfaces. This includes the removal of fatty contaminants, the disinfection of dishes, the washing of cutlery in everyday life and in public catering establishments.

 However, despite the presence in the formulation of glycerol as an emollient, the product has a drying effect on the skin of the hands and, with constant use, in some cases causes allergic reactions.

 The invention solves the problem of creating a cleaning product without harmful effects on the skin of the hands with an increased bactericidal effect and improves the smell of the drug.

The goal is achieved by the fact that in the proposed cleaning agent containing nonionic surfactants, urea, glycerin and water, a complex CO ₂ extract from carrot seeds and barley sprouts or from carrot seeds and rice flour or their hydrophytoconcentrates, CO ₂ dill extract or maltol taken in the following ratio, wt. Nonionic surfactants 20-40 Urea 3.0-8.0 Glycerol 2.0-5.0
Complex CO ₂ extract from carrot seeds and barley sprouts or Complex CO ₂ extract from carrot and rice flour seeds or their hydrophytoconcentrates 0.001-1.0 CO ₂ dill extract or 0.001-0.5 Maltol 0.0001 -0.01 Water Up to 100
The introduced phytocomposition, consisting of plant CO ₂ extracts and maltol, enhances the bactericidal action and improves the odor. The cleaning agent does not have allergenic, skin-irritating properties, meets hygienic requirements and consumer tastes.

The listed properties of the cleaning agent are achieved due to the combination in the formulation of the optimal amounts of CO ₂ extracts with other components of the new product being developed taking into account the combined action with the surfactant.

Complex CO ₂ extract from carrot seeds and barley sprouts (N 13) corresponds to TU 10.048549-041-91 and is a mixture of vitamin substances of carrot seeds and barley sprouts, balanced at the stage of preparation and extraction. Extractives of carrot seeds are a vitamin complex of plasticizing, regenerating and nourishing effects. Biologically active acids, tocopherols, sterols, carotenoids, phospholipids are transferred to the complex CO ₂ -extract with extractive substances of carrot seeds. The content of trace amounts of vitamin A (carotene) in the extract has a huge physiological role. It takes part in redox processes, is a carrier of hydrogen and oxygen, affects enzymatic processes, keratization of the epithelium, and the metabolism of fats and carbohydrates.

 Polyunsaturated fatty acids linoleic and linolenic constitute a factor of vitamin F. Fatty oil, combining the properties of oils of carrot seeds and barley sprouts, is a good plasticizer and synergist for vitamin E (tocopherols). With the extractive substances of barley sprouts, lipids represented by triglycerides, phospholipids, waxes, sterols, their constituent acids are linoleic, oleic, palmitic, stearic, myristic, linolenic, are extracted into the complex extract. The lipids and tocopherols of barley sprouts in combination with the extractives of carrot seeds provide a nourishing effect. Tocopherols of seeds of carrots and barley sprouts stabilize the content of carotenoids. Tocopherols are able to accumulate in lipids of various layers of the skin, which in combination with other biologically active components increase the skin's resistance to the development of age-related changes, to radiation. The lipid fraction of the extract provides a balanced thickness of the protective layer on the surface of the skin of the hands through which, on the one hand, nutrients penetrate, and on the other hand, it protects the skin from surfactant surpluses, which, when deeply penetrated into the skin, lead to a sharp degreasing, peeling of the skin of the hands, a feeling of tightness after washing.

The complex СО ₂ extract from carrot seeds and rice waste (N 15) corresponds to TU 10.048549-041-91 and is a vitaminizing and aromatizing complex of plasticizing, regenerating and nourishing effects. Wax, tocopherols, carotenoids, and lipid complex were found in the composition of the complex CO ₂ extract N 15. Linoleic, linolenic, oleic, myristic, palmitic, stearic are identified in the composition of high molecular weight unsaturated fatty acids. Waxes of rice wastes and complex СО ₂ -extract N 15 have high biological activity and increase the stability of labile biologically active components. The stabilization of their content for a long time is provided by the presence of tocopherols, which have an antioxidant effect. Belongs to the carotene-containing group. Carotenoids have anti-infectious properties, affect the permeability of cell membranes, prevent dry skin, and reduce tissue acidity.

Due to the identity of the component composition in the presence of waxes, acids, lipids, vitamins, volatile fractions in the composition of essential oils, the proposed complex CO ₂ extracts are interchangeable.

 Hydrophytoconcentrates of these raw material mixtures are a biologically active complex of water-soluble substances, contain an active plant fraction enriched with vitamin C, chlorophyll, flavonoids, have high permeability and the ability to ensure blood flow to the skin of the hands, which maintains skin-fat balance and prevents dryness.

The CO ₂ dill extract consists of saponifiable, unsaponifiable substances, alcohols, hydrocarbons, carbonyl and other compounds. Dill essential oil contains the following components: pinene, camphene, myrcene, dipentene, limonene, borneol, geraniol, carvone. The main components of the free acid fraction are linoleic, oleic, palmitic. Low molecular acids of this fraction are mainly represented by valerianic and oxalic. The extract has anti-inflammatory and antiseptic effects.

 Maltol is a well-known product obtained from coniferous raw materials (fir), is widely used in the food industry as an aromatic and flavoring additive, as this substance has a pleasant persistent odor and exhibits the properties of a stabilizer for fragrances and aroma.

 Glycerin, attracting the liquid constituents of blood to itself, makes the surface layers of the skin into which it is absorbed soft, juicy, as if transparent. Nutrients penetrate the moistened stratum corneum of the skin much more easily than through the dry one.

 Waxes and sterols of extracts, introduced into the formulation together with glycerin, provide swelling and enhance skin penetration, creating a thin film on its surface, which, on the one hand, is protective, it protects the skin from surfactant surpluses, which, when deeply penetrated into the skin, lead to dryness , irritation, and on the other, promote the penetration of nutrients into the skin. This penetration is possible if the extracts are introduced into the formulation together with glycerin.

 If the skin is often washed, or for other reasons it is in frequent contact with detergents, substances that maintain moisture disappear from it. Detergents remove fat-soluble substances from the skin, further contributing to the removal of water-soluble substances. A decrease in the content of both fat and water soluble substances in the stratum corneum disrupts the water-fat balance and reduces the ability to retain water. When the water content in the stratum corneum decreases to 10% or lower, signs characteristic of dry skin appear: a feeling of dry skin, rough surface, the appearance of small cracks.

 Using moisturizers removes the unpleasant feeling of dry skin.

 Humidifiers are substances that locally increase the amount of water or retain water in the stratum corneum. Some of them are hygroscopic, others form solutions with other substances and with water, from which water evaporates weakly, so we can say that they retain water. As humidifiers, mainly substances contained in the stratum corneum proper and regulate humidity are used. The most important in this group is urea.

 This type of hydrotropic substances breaks hydrogen bonds in water, closing them on itself. Carbamide, destroying the structure of water, complicates the formation of micellar and liquid crystal structures of surfactants, increasing the thermodynamic compatibility between water and surfactant molecules.

The combination of carbamide with exhausting substances and waxes of CO ₂ extracts or hydrophilic complexes of HFC ensures the stability of the water-fat balance of the stratum corneum of the skin of the hands, increases blood flow and thereby reduces dryness and peeling of the skin. Micromolecules of hydrophilic and hydrophobic substances introduced with vegetable biologically active substances ensure the stability of suspensions of contaminants in an aqueous solution of surfactants, thereby increasing the cleaning and washing effect.

 Thus, as a result of a combination of known substances with plant biologically active substances introduced into the recipe, a new highly effective agent with a gentle effect on the skin is obtained.

The effect of dosages of complex and individual CO ₂ extracts on the quality indicators of the cleaning agent in order to select the boundary concentration values of these biologically active components of the formulation was studied using mathematical planning on a simplex. The composition of the mixture of extracts and neonol was varied. The dosage of the remaining components was fixed at the same level. Optimizing parameters were the content of tocopherols and washing ability.

To analyze the relationship between:
-concentration of complex CO ₂ -extract N 13 or CO ₂ -extract N 15 or their HFC, CO ₂ -extract of dill and surfactant;
the concentration of complex CO ₂ -extract N 13 or CO ₂ -extract N 15 or their HFC, maltol and surfactant and the investigated characteristics of the cleaning agent used a second-order equation for three-component mixtures:
P = β ₁ x + β ₂ x ₂ + β ₃ x ₃ + β ₁₂ x ₁ x ₂ +
+ β ₁₃ x ₁ x ₃ + β ₂₃ x ₂ x ₃ + β ₁₂₃ x ₁ x ₂ x ₃ , where П is an indicator of the quality of the cleaning agent;
β _n , β _{nm are the} coefficients of the equation;
x _{n are the} proportions of the variable components.

 The plan and data of experimental studies are shown in tables 1 and 2.

 The data obtained were processed and analyzed using Sheffe simplex lattices in a composition-property system that takes into account the interdependence of detergent quality indicators on the ratio of components in extract mixtures.

Analysis of regression equations An analysis of the relationship between the composition of mixtures of CO ₂ extracts, maltol and surfactants showed that to achieve a high content of biologically active components, it is necessary to introduce 0.001-1.0% of complex CO ₂ extract N 13 or CO ₂ extract N 15 or their HFC, 0.001-0.5% CO ₂ -extract of dill, 0.0001-0.01% maltol and 20-40% surfactant.

The combination of the natural components of the aromatic effect in the complex CO ₂ -extracts N 13 or N 15, dill or maltol gives the product a mild aroma of natural raw materials. The introduction of maltol or dill essential oil provides an additional bactericidal effect, which is especially important when washing dishes for food purposes.

Preparation of liquid detergent is dosed according to the formulation and the dissolution of the individual components under stirring and heating to 60-70 ^{° C,} cooling to 40-50 ^C, and entering the individual integrated CO ₂ extracts and packing.

Preparation Example: into the mixer through the balance of the containers charged neonol AF-9-12 4.0 kg glycerol 0.5 kg and water 94.599 kg, the solution was heated to 60-70 ^{° C} and then charged with 0.8 kg of urea to complete dissolution solid components. After obtaining a homogeneous mixture of clear solution was cooled to 40-50 ^C and 0.1 kg administered CO ₂ extract of complex N 13 or N 15, or GFK, 0.05 kg CO ₂ extract of dill or 0.001 kg maltol. After mixing, the solution from the mixer is fed either to the filter or to the sumps of the finished liquid detergent and fed to the bottling.

All components of the cleaning agent in combination with complex and individual CO ₂ -extracts or HFC at the selected dose limits provide the agent with a bactericidal effect, reduce the harmful effects on the skin, strengthen and deepen the aroma.

 The introduction of a new dishwashing detergent is expected at the Moscow factory of synthetic detergents.
