Description

Plant acarid-removing and acarid-inhibiting laundry detergent and preparation method thereof

The technical field is as follows:

the invention relates to the field of washing products, in particular to a plant acarid-removing and acarid-inhibiting laundry detergent and a preparation method thereof.

Background art:

the laundry detergent is a detergent variety which is developed rapidly in recent years in fabric care markets at home and abroad. In China, the laundry detergent has already entered families of common people, and with the continuous improvement of living standard, the requirements of people on the laundry detergent are no longer only satisfied with the basic decontamination efficacy, and the laundry detergent is expected to have other functions, such as: bacteriostasis, mite killing and other effects. The bacterial mites can be found anywhere, such as clothes, bed sheets, underwear, bedding and the like. Clothes are easy to inhabit a large number of mites, which causes allergic skin diseases; the prior laundry detergent for killing mites on the market is divided into two types, one type is that the laundry detergent is added with chemical components to achieve mite killing, the chemical components kill mites, the mite killing effect is poor, mites are easy to generate drug resistance, after the laundry detergent is used for a long time, the mite killing effect is avoided, the lasting mite inhibiting effect is lacked, and the residual chemical components are easy to damage clothes and skin. The other is that the plant acaricidal component is added into the laundry detergent, so that the acarid cannot generate drug resistance, and the acarid killing effect can be maintained for a long time, but the plant acarid killing component is added into the laundry detergent, so that the plant acarid killing component is sensitive to air, sunlight, temperature and the like, the components added into the laundry detergent are unstable, the deterioration is easy to occur, the acarid killing effect is unstable, the acarid killing effect is easy to lose, the components in the plant component are partially deposited on white clothes, and the white clothes and the like are dull after long-term washing. In addition, the existing laundry detergent generates too much foam, which causes liquid overflow when the washing machine washes the laundry detergent, a large amount of water is wasted in both machine washing and hand washing, and after the laundry detergent washes away dirt, a small part of oil dirt is deposited again and deposited on the surface of clothes, so that the decontamination effect of the laundry detergent is not ideal, and therefore, it is urgently needed to develop a laundry detergent which removes bacteria, mites, dirt and the like attached to the laundry detergent while washing the clothes and does not settle again.

The invention content is as follows:

the invention aims to overcome the defects in the prior art and provides the plant acarid-removing and acarid-inhibiting laundry detergent and the preparation method thereof.

The technical scheme adopted by the invention is as follows: the plant mite-killing and mite-inhibiting laundry detergent comprises the following components in percentage by weight: 8-25% of vegetable oil A, 8-25% of surfactant, 1-5% of alkali, 10-25% of traditional Chinese medicine extract, 0.3-1.5% of vegetable oil B and the balance of water.

Preferably, the laundry detergent comprises the following components in percentage by weight: 15-20% of vegetable oil A, 13-19% of surfactant, 2-4% of alkali, 15-20% of traditional Chinese medicine extract, 0.5-1.0% of vegetable oil B and the balance of water.

Preferably, the laundry detergent comprises the following components in percentage by weight: 18% of vegetable oil A, 16% of surfactant, 3% of alkali, 15% of traditional Chinese medicine extract, 1.0% of vegetable oil B and the balance of water.

Preferably, the surfactant comprises the following components in percentage by weight: 3-10% of cocamidopropyl betaine, 2-5% of potassium cocoyl glycinate and 3-10% of myristyl glucoside.

Preferably, the component of the vegetable oil A and the weight percentage of each component are 1-5% of palm oil, 1-5% of rapeseed oil, 1-5% of olive oil and 5-10% of chinaberry oil.

Preferably, the alkali is selected from any one, any two or a mixture of any two or more of potassium hydroxide, sodium carbonate and triethanolamine. The soap solution prepared by reacting the sodium carbonate, the triethanolamine and the vegetable oil A has low detergency, but can be used as a softening agent to soften fabrics, improve the hand feeling of the laundry detergent, improve the luster of the fabrics, enhance the dyeing fastness of the fabrics and enable the fabrics to be more bright in color. The soap liquid prepared by the reaction of the sodium hydroxide and the vegetable oil A has poor solubility and high freezing point, and the soap liquid prepared by the reaction of the potassium hydroxide and the vegetable oil B has good solubility and low freezing point, so that the optimum implementation mode of the invention is to perform saponification reaction of the potassium hydroxide and the vegetable oil A to improve the compatibility and the solubility of the soap liquid, so that the prepared laundry detergent has more uniform components and better hand feeling.

Preferably, the components of the traditional Chinese medicine extract and the weight percentage of each component are 2-5% of the extract of the root of flavescent sophora root, 2-5% of the extract of the tuber of stemona, 2-5% of the extract of honeysuckle, 2-5% of the extract of common cnidium fruit and 2-5% of the extract of common andrographis herb.

Preferably, the component of the vegetable oil B and the weight percentage of each component are 0.1-0.5% of lavender oil, 0.1-0.5% of green zanthoxylum oil and 0.1-0.5% of peppermint oil.

A preparation method of a plant acarid-removing and acarid-inhibiting laundry detergent comprises the following steps:

the method comprises the following steps: stirring and mixing the vegetable oil A with the formula ratio, and heating to 60-70 ℃;

step two: dissolving the formula amount of alkali with the formula amount of water, slowly adding the alkali liquor into the vegetable oil A in the step one, stirring and keeping the temperature for 50-60min at 75-80 ℃, fully saponifying, and slowly cooling to 40-45 ℃ for later use;

step three: sequentially adding the surfactant, the traditional Chinese medicine extract and the vegetable oil B into the soap liquid obtained in the second step, uniformly stirring, and discharging after the inspection is qualified; the lavender oil, the zanthoxylum oil and the mint oil are volatile vegetable oil, if the volatile oil is added in the saponification process, the volatile oil can volatilize from a reaction container or deteriorate at high temperature to lose activity, so that the activity of the vegetable oil B is influenced, and therefore, the volatile oil is added at low temperature after saponification, so that the effect of active ingredients in the vegetable oil B can be ensured.

Step four: filling and packaging to obtain the finished product.

Saponification is an ester hydrolysis reaction which takes place under the catalysis of alkali, especially the reaction of alkali and grease. In a narrow sense, the saponification reaction is a reaction between fats and oils and potassium/sodium hydroxide, which finally produces higher fatty acid salts and glycerin. The glycerin generated by the saponification reaction can weaken the thickening property of the cocamidopropyl betaine in the formula of the laundry detergent, reduce the system viscosity of the prepared laundry detergent and improve the low-temperature transparency of the laundry detergent containing the cocamidopropyl betaine. The soap base system generated in the saponification reaction process can irritate the skin, easily causes the phenomena of allergy, skin surface irritation, red swelling and the like, and how to avoid the irritation of the saponification reaction product is still a difficult problem in the industry at present.

Cocamidopropyl betaine (CAB) is the most commonly used amphoteric surfactant, is stable in a wide pH range, can be compatible with anionic surfactants and other nonionic surfactants, and is convenient to use. The detergent has the obvious characteristics of low irritation to eyes and skin, mild surfactant, good cleaning and foaming performances, more foams, strong detergency, excellent thickening performance, softness, bactericidal performance, antistatic performance and hard water resistance, and can obviously improve the softness, conditioning performance and low-temperature stability of washing products.

The cocoyl potassium glycinate is amino acid surfactant, has mild property, dense and rich foam, is easy to wash, has strong foaming power under neutral or alkaline conditions, and can improve the quality of the foam. The cocoyl potassium glycinate added in the invention can improve the washing feeling of a soap base system generated by saponification reaction and reduce the irritation thereof, thereby enabling the whole laundry detergent system to be mild and non-irritant, and solving the irritation problem commonly existing in the soap base.

As a surfactant which is commonly used in the industry and is suitable for a facial cleansing product, coconut acyl potassium glycinate is easy to have the problems of thin material body, weak foaming capacity, poor stability, particle precipitation after long-time placement, rough material body, layering and the like in the development process. In the laundry detergent system, the foaming amount of cocoamidopropyl betaine and myristyl glucoside can be effectively reduced by adding the potassium cocoamidoglycinate, the dissolution of the potassium cocoamidoglycinate is promoted by the interaction of the potassium cocoamidoglycinate and other surfactants, and the layering of the potassium cocoamidoglycinate is avoided. In addition, the applicant has found that the laundry detergent generates moderate amounts of foam when used, both in machine washing and in hand washing, the applicant conjectures that the glycerol generated by saponification reaction plays a certain defoaming role in the field of the laundry detergent, the glycerol has certain water solubility, the water structure is destroyed by the action with water molecules, the glycerol can be attached on the surface of the air bubble or penetrate through the air bubble to enter the air bubble, when glycerin is attached to the surface of the bubbles, the bubbles are easy to enlarge, after the bubbles are enlarged, the bubble walls are broken, when the glycerin enters the air bubbles through the air bubbles, the air bubble walls can be broken, so that the air bubbles generated by the laundry detergent system are moderate, the rinsing is convenient, the overflowing is prevented, and the water waste is caused during the laundry.

The myristyl glucoside is a surfactant of alkyl glucoside, and has excellent decontamination, foaming, foam stabilization, emulsification, dispersion, solubilization, wetting, penetration capacity, acid resistance, alkali resistance, insensitivity to electrolyte, and reduced irritation of other surfactants.

Honeysuckle flower: the efficacy of the traditional Chinese medicine is mainly to clear away heat and toxic materials and mainly treat epidemic febrile disease fever, heat toxin and bloody dysentery, carbuncle, cellulitis, furuncle and the like. Contains chlorogenic acid, luteolin glycoside and other pharmacologically active components, and has strong inhibitory effect on hemolytic streptococcus, Staphylococcus aureus and other pathogenic bacteria and upper respiratory infection pathogenic virus.

Stemona root: cough and ascending of qi. It is indicated for liquor stir-baked with fire (Bie Lu). Treat lung heat and moisten lung (check right). For bone-steaming fatigue in dead body, malnutrition, ascarid, cun-Bai, pinworm and all kinds of wood-boring insects, which die after being eaten. Killing lice and flies and midges (the expression of Hongjing is that the lice are removed by washing cattle and dogs in soup). For scabies and tinea, the toxin is bitten by silkworm (Tibetan device) after the fire-stir-baked wine is soaked in the empty stomach.

Flavescent sophora root: the heat-clearing and dampness-drying herbs are mainly used for: dysentery due to damp-heat; hematochezia due to intestinal wind; jaundice; difficulty in urination; edema; leucorrhea; pruritus vulvae; scabies; leprosy; itch of the skin; sores and ulcers due to damp toxin.

Fructus Cnidii is dried mature fruit of cnidium monnieri (L.) DC of Umbelliferae, has pungent and cool taste, enters kidney channel, and has effects of warming kidney, tonifying yang, dispelling pathogenic wind, eliminating dampness, and killing parasite.

Andrographis paniculata, also known as Yijianxi, Kudancao, Sifangcao, etc., has the main actions of clearing heat and removing toxicity, cooling blood and relieving swelling, and also has the action of expelling superficial evils, so it is indicated for all heat-toxin syndromes. It is used for treating common cold, fever, sore throat, cough, diarrhea, dysentery, mosquito bite, etc. Modern medical research proves that the andrographis decoction has a certain inhibiting effect on leptospira, pneumococcus, streptococcus agalactiae and catacoccus.

Palm oil, it is mainly extracted from oil palm pulp, become semisolid at the normal temperature, its melting point and viscosity are mainly influenced by content of free fatty acid, its saturated fatty acid content is higher, stability is good, it is difficult to be oxidized and rancid, the soap made from it can play a durable foam and have stronger detergency, but palm oil contains more carotene (0.05% -2%), so generally it is orange red, alkali refining can't remove this pigment effectively, therefore, often need hydrogenation, hydrogenate, reduce the degree of unsaturation in order to improve the pigment.

The lavender oil is colorless to light yellow liquid, the relative density is 0.880-0.900, and the refractive index is 1.465-1.470. The main components are linalyl acetate, linalool, lavender alcohol, lavender acetate ester, p-1-menthene-4-ol, terpineol, caryophyllene and alloocimene, and small amount of 1, 8-cineole and camphor.

Peppermint oil is a clear liquid that is colorless or yellowish. Has special cool fragrance, pungent taste and cool aftertaste. The color of the tea is gradually deepened after the tea is stored for a long time. Is often used for repelling mosquitoes and relieving body fatigue.

The lavender oil, the peppermint oil and the zanthoxylum oil are volatile plant essential oils which are matched with each other, so that the laundry detergent can be endowed with special cool fragrance, clothes can be fragrant after clothes are washed, the clothes can be prevented from mildewing, the special effects of expelling insects and the like can be realized, in addition, the plant essential oil can inhibit the propagation and growth of mildew and the like by generating irreversible damage to cell walls, cell membranes and organelles of mites or bacteria and the like and promoting the decomposition of hyphae of the fungi and the like during mite killing, sterilization and the like, and the bacteria and the like are fundamentally inhibited. The plant essential oil and the traditional Chinese medicine extract are mutually matched, have a synergistic effect and a good sterilization effect, and can prevent microorganisms, parasites and the like from generating drug resistance to single active ingredients. The vegetable oil B can volatilize when being added into the common laundry detergent, and the vegetable oil B can volatilize in the storage process of the laundry detergent.

The lightyellow sophora root, the sessile stemona root, the honeysuckle, the common cnidium fruit and the common andrographis herb are all traditional Chinese herbal medicines for resisting bacteria and removing mites. Many data report that matrine, stemonine, chlorogenic acid, osthole and andrographolide in the plant extracts have wider antimicrobial and deinsectization functions. The plant extract has low effective component, and several extracts have synergistic effect, so as to prevent the drug resistance of microorganisms and parasites to single active component. When the traditional Chinese medicine extract is used, active ingredients in the traditional Chinese medicine extract are sensitive to air, sunlight, temperature and the like, and are easy to deteriorate or volatilize.

The vegetable oil and the traditional Chinese medicine extract are added into the laundry detergent, cross network structures, micelle structures and the like are formed between macromolecules such as fatty acid salts generated by saponification and surfactants, the vegetable oil B and the traditional Chinese medicine extract are repeatedly wrapped, the vegetable oil B and the traditional Chinese medicine extract are limited between the cross network structures and between the micelles, the volatilization of the vegetable oil B is avoided, and the heat resistance, the light resistance and the like of the traditional Chinese medicine extract are improved. Therefore, the problems of volatilization of the vegetable oil B, deterioration of the traditional Chinese medicine extract and the like are solved, the phenomena of dull color, color change and the like of the fabric caused by deposition of dirt and the traditional Chinese medicine extract on the surface of the fabric can be avoided, and the color of the fabric and the color fixing effect of the color can be improved by the oxidation components in the traditional Chinese medicine extract.
