Description

The invention relates to liquid detergent compositions for household use, namely, detergents for washing dishes.

Almost all known detergent compositions are based on cleaning surfactants, foam enhancers, pH-controlling agents, in addition, known compositions contain, as a rule, auxiliary additives that provide dishwashing detergents with attractive aesthetic properties - pleasant smell, color.

Known liquid detergent composition for washing dishes containing a system of surface-active substances, including alkyl / C ₁₀ -C ₁₆ / alkene or alkaline earth metal benzenesulfonate 7.5-20.0, alkaline salt of alkyl / C ₁₀ -C ₁₈ / sulfosuccinate or sulfosuccinamate 0.5-8.0, alkaline salt of ethoxylated alkyl / C ₁₀ -C ₂₀ / sulfate 8.0-20.0, an alkyl polyglucoside having an average of 12 to 16 carbon atoms in the alkyl chain and with an average degree of polymerization of 1 to 3 3.0-12.0, a foam stabilizer based on at least one lower alkanolamide higher carbon slots 0.5-6.0, organic solvent no more than 10.0, hydrotrop no more than 8.0, one or more functional additives no more than 20.0 and water up to 100, and the total number of surfactant system and foam stabilizer is 25-54% for the entire composition (RF patent No. 2073700, MKI C11D 1/12, publ. 02.20.97)

The disadvantage is that the indicated dishwashing detergent effectively removes fatty residues, as well as other types of contaminants from the dishes only when using room, medium or high temperature water, and at low temperatures the emulsifying and cleaning ability of the detergent drops. The specified tool is also not designed for use in water of increased stiffness. In addition, the mixture of anionic surfactants (surfactants) in the composition of the product has a high effect of irritation and drying of the skin of the hands.

As a prototype, a liquid detergent with the following content of components was selected, wt.%: Sodium alpha-olefin sulfonate 10.0-25.0; amine oxide 2.0-4.0; betaine 0.5-5.0; an ethoxylated fatty alcohol C ₁₂ -C ₁₅ having the chemical formula C _12/15 H _25/31 -O- (CH ₂ -CH ₂ -O) ₅ -H 1.0-5.0; glycerol 0.1-1.0; tetrasodium salt of ethylenediaminetetraacetic acid 0.1-0.6; trisodium salt of nitriloacetic acid 0.01-0.5; viscosity modifier 1.0-10.0; dye 0.0015-0.005; flavoring 0.2-0.6; preservative 0.03-0.2; an agent providing a pH of 6-8.5 0.2-1.0; demineralized water to 100% (RF patent No. 2241741, MKI C11D 1/94, publ. 12.10.2004).

The specified detergent provides a washing ability at different temperatures and in water of different hardness. However, a complex mixture of anionic and nonionic surfactants in the composition of the specified detergent has an irritating and drying hand skin property, despite the presence of glycerol in the composition. In addition, the complex composition of the product worsens its environmental properties, increases the cost of detergent and complicates the process of its production.

The objective of the invention is to provide a mild liquid detergent with high washing ability by increasing the fat-cleaning effect and without harmful effects on the skin of the hands, reducing the cost of the resulting product, increasing the environmental friendliness of the product, as well as expanding the range of liquid detergents.

The problem is solved in that the liquid detergent contains a system of surfactants, including sodium alpha olefin sulfonate or sodium alkyl sulfate, sodium sulfoethoxylate and alkyl dimethylamine oxide or cocoamidopropylamine oxide, as well as the tetrasodium salt of ethylenediamine-tetraacetic acid, 2-methylazole-4-iso-4-from-3-from-3-out -one, sodium chloride, colorants, flavoring agent, phosphoric acid, an additive to protect the skin of the hands and water, while the product also contains an extract of vitamin E or silt as an additive to protect the skin of the hands aloe vera gel, or an extract of peach or lemon extract or apple extract, or an extract of almond milk, and these components are shown in the following ratio, wt.%:

Sodium alpha olefin sulfonate or Sodium Alkyl Sulfate 13.0-16.0 Alkyldimethylamine oxide or cocoamidopropylamine oxide 2.0-4.0 Sodium Sulfoethoxylate 0.1-4.0 Tetrasodium salt ethylenediaminetetraacetic acid 0.1-0.4 Sodium chloride 0.1-6.0 Hand Protector 0.1 Dyes 0.001-0.01 Flavoring 0.3-0.5 2-methyl-4-isothiazolin-3-one 0.05-0.1 Orthophosphoric acid 0.1-0.5 Demineralized water The rest is up to 100%

The technical result obtained from the use of the proposed composition, is to improve the washing qualities, reduce consumption and environmental friendliness.

The proposed qualitative and quantitative composition of the product is necessary and sufficient to achieve the specified result.

The product contains a balanced composition of surface-active substances: anionic and nonionic, which reduces the consumption of the number of loaded components and the harmful effects on the skin of the hands, as well as increases the environmental friendliness of the product.

Optimally selected content and ratio of detergent components can reduce the total amount of surfactants and create a more effective surfactant system with high detergent characteristics. The claimed content and amount of anionic and nonionic surfactants in the tool increases the effectiveness of the detergent due to the phenomenon of synergism - mutual enhancement of the action of the components.

It is also possible to increase the washing characteristics by increasing the solubility of surfactants: each component of the surfactant system is indifferent to hardness salts and prevents the formation of deposits of indelible stiffness salts on dishes.

As the anionic sulfonate surfactant according to the invention, alpha olefin sulfonate (it is less sensitive to hardness salts present in water), taken in the form of a 35% solution or sodium alkyl sulfate, taken in the form of a 28-30% solution, is used. Their content in the composition of the inventive detergent provides effective removal of fatty residues, as well as other types of contamination from dishes in medium hardness water (5.35 mg Ca ²⁺ / g) and in water called "hard", while this effect is achieved as at room and at a lower temperature.

Alkyldimethylamine oxide or cocoamidopropylamine oxide are used as a foam enhancer, which, being also a component of the surfactant system, contribute to the effective cleaning of the contaminated surface.

The second anionic surfactant of the surfactant system of the proposed detergent is sodium sulfoethoxylate (with 2 or 3 moles of ethylene oxide). This product acts as a cleaning detergent.

The combination of these components of the surfactant system provides the inventive detergent stable gel-like structure, contributing to the cost-effectiveness of its use.

Thus, the selected detergent composition allows you to quickly and efficiently clean dishes from grease and dried food residues, dissolving dirt, putting it into suspension and washing it off with a stream of water, forms a thick foam, which increases the cleaning efficiency.

Traditionally, glycerin is used in detergent formulations as an additive to protect hand skin. In addition to glycerin, the proposed detergent also uses other additives to protect the skin of the hands, expanding the product range and providing the consumer with a choice of detergent compositions that meet his needs. Due to the optimal composition of the surfactant system in combination with the proposed additives, the claimed tool does not cause allergies in people with sensitive skin.

Glycerin is used as a water-retaining additive for hand skin care, as it forms a water-retaining film on the surface of the skin, softens the skin, protecting the stratum corneum from drying out, and increases the resistance of skin cells to low temperatures.

Aloe vera gel extract has a healing, bactericidal, tonic effect on the skin due to the content of allantoin. In addition to allantoin, aloe contains natural antioxidants in the form of vitamins B complex, vitamins C and E, as well as beta-carotene. All of these nutrients are very important for healthy skin. It is especially recommended for use in preparations for sensitive skin. Tones up skin cells, eliminates irritation, normalizes the water-fat balance of the skin, exhibits decongestant and antipruritic effects, promotes tissue regeneration after burns.

Lemon extract is valuable due to the content of vitamin C, sugars, citric acid, has a tonic, whitening and refreshing effect on the skin, prevents the development of lipid peroxidation processes.

Apple extract is used as a nutritious, moisturizing, fortifying, softening, tonic, anti-inflammatory and refreshing component due to the content of vitamin A and group B vitamins in its composition, useful, in particular, for skin and nails.

Peach extract is a source of vitamin B ₁₅ (pangamic acid), which has high biological activity. Peach extract also softens, moisturizes and nourishes the skin with vitamins C and E.

Almond milk extract has a good emollient and nourishing effect due to the content of almond oil in its composition, which is 95% composed of valuable fatty acids (linoleic acid, etc.), which restore the barrier functions of the skin. The tocopherol (vitamin E) and β-sitosterol contained in almond oil activate skin regeneration processes, soften and nourish it. Almond oil regulates the permeability of the epidermal barrier, lipid and water balance of the skin, activates the regeneration process. Therefore, almond milk has nourishing and regenerating properties, favorably affects dry skin, relieves irritation and inflammation, softens the skin, normalizing metabolic processes and fluid balance in the skin cells, thereby restoring skin elasticity and elasticity.

Vitamin E extract has antioxidant properties, protects the skin from the negative effects of free radicals, regulates the water balance of the skin, protects the lipid layer of the epidermis from destruction, slows down the aging process of the skin.

Thus, the use of the above additives provides maximum care and protection for the skin of the hands, which allows people with sensitive skin to use it without fear.

In addition to these essential components, the inventive detergent contains sodium chloride as a modifier of viscosity, tetrasodium salt of ethylenediaminetetraacetic acid as complexon, as a preservative 2-Methyl-4-isothiazolin-3-one, as well as dyes, flavoring (perfume) and orthophosphoric acid, providing a pH of 6.0-9.0.

The role of the complexing agent is played by the tetrasodium salt of ethylenediaminetetraacetic acid (manufactured in industry under the trade name Trilon B). The selected optimal composition of the components allows only one complexing agent to be contained in the composition, which reduces the harmful effects on the skin of the hands, and also allows to simplify the composition of the product while increasing the washing characteristics.

As a preservative, the inventive liquid detergent mainly contains 2-Methyl-4-isothiazolin-3-one (or a mixture of methylisothiazolinone, benzylisothiazolinone, methylchloroisothiazolinone), mainly taken in the form of a 9.5-9.9% solution.

As a dye, the product contains Tartrazin 85 E 102 and Iragon Blau ABL 9.

As a flavoring agent, the product contains, for example, a perfumery composition fragrance with a grapefruit aroma having the trade name Red Grapefruit or a perfumery composition fragrance providing a lemon aroma having the trade name Lemon Squeeze and other perfumes such as Nefis Almond 058IE (for “AOS” almond milk ), Apfel with the scent of apple, E Shinning Peach with the scent of peach and SPA Waters (for the name “AOS Aqua”). Aromatic additives give the product a pleasant smell.

It retains its qualities during storage for a long time without discoloration or loss of any insoluble substances.
