Description

Technical Field

[0001] The present invention relates to the technical field of washing and cleaning, and in particular to an antibacterial washing and cleaning tablet and a preparation method and a use method thereof. Background Art

[0002] At present, shampoo products are mainly in the form of liquid or gel, usually packaged in plastic bottles, and the specifications are mostly 100-1000mL, which is suitable for many personal or family use, but for the tourism and hotel industries, the demand for small-dose shampoo products is higher. Shampoo cleaning tablets are an innovative shampoo product that comes in sheet form and is more portable and environmentally friendly than traditional liquid shampoos. When using, just put a shampoo cleaning tablet into an appropriate amount of water to dissolve, or rub it directly on wet hair to produce foam, and then perform the usual shampooing steps. It is small in size and easy to carry, which is very suitable for travel or business trips. It reduces the use of packaging materials, especially the use of plastic bottles, which helps to reduce environmental pollution. It has the advantages of hygiene, quantitative, easy to carry, and environmental protection, and has great application prospects.

[0003] Since the form and usage conditions of shampoo tablets are significantly different from those of traditional shampoos, there are many technical problems that need to be solved in their formulations, such as (1) Solubility: Shampoo tablets need to dissolve quickly and effectively in water in order to quickly generate enough foam to clean the hair. To achieve this, the ingredients in the formula must be able to dissolve quickly without sacrificing the cleaning effect and gentleness to the scalp. (2) Stability: Compared with liquid shampoo, solid shampoo tablets need to maintain their physical form for a long time, which means that the ingredients in the formula need to have good stability and durability to prevent deterioration due to temperature changes or humidity. (3) Cleansing ability: Shampoo tablets need to have effective degreasing and cleaning abilities to meet consumers' basic needs for hair cleansing. This requires that the cleaning ingredients in the formula can be effectively present in the cleaning tablet carrier. (4) Moisturizing and care: In addition to the basic cleaning function, modern consumers also expect shampoo products to provide additional scalp care and hair conditioning effects. Therefore, it is a challenge to add effective nourishing ingredients in a limited space while keeping other product properties intact.

[0004] In the prior art, sulfate surfactants represented by sodium fatty alcohol sulfate (mainly sodium alkyl sulfate SLS) and sodium fatty alcohol polyether sulfate are the main surfactants in current cleaning products. Chinese patent CN105769615A provides a portable shampoo tablet and its preparation method, which has a certain cleaning effect on several stains on hair. However, on the one hand, the formula contains sodium lauryl ether sulfate surfactant that is easy to produce dioxane; the chelating agent tetrasodium ethylenediaminetetraacetic acid used is also easy to cause skin itching and allergies, and is not environmentally friendly. On the other hand, 15-20% of ordinary starch with poor water solubility is added as a filler. When used as a shampoo product, due to the small amount of water used and the low water temperature, the starch will remain on the hair.

[0005] Chinese patent CN105796385A provides environmentally friendly super-concentrated shampoo tablets / granules and their production methods, in which sodium lauryl polyoxyethylene ether sulfate (AES) accounts for 58% of the formula, which may bring more dioxane into the shampoo tablets. Chinese patent CN106726634A provides a sheet-like shampoo product, in which sodium lauryl sulfate (SLS) accounts for 10-40% and AES accounts for 1-10%, which has too strong cleaning power and is not suitable for long-term use.

[0006] Therefore, developing an antibacterial cleaning tablet has great application prospects. Summary of the invention

[0007] The object of the present invention is to provide an antibacterial cleaning tablet. The antibacterial cleaning tablet of the present invention does not add SLS surfactant, does not add ethoxylated surfactant, and does not add preservatives. It has the advantages of mild cleaning, strong solubility and inhibition of Malassezia, and can be used for daily shampooing, hand washing, and cleaning underwear.

[0008] The first aspect of the present invention provides an antibacterial cleaning tablet. The raw materials for preparation include, by weight: 10-30 parts of a film-forming agent, 10-40 parts of a surfactant, 1-10 parts of a filler, 0.5-6 parts of a chelating agent, 0.5-5 parts of a hair conditioner, 0.5-5 parts of a plant extract, 1-5 parts of an auxiliary agent, 0.1-1 parts of an antibacterial agent, 0.1-1 parts of a fragrance, and 10-100 parts of deionized water.

[0009] In some embodiments, the film-forming agent includes film-forming agent A and film-forming agent B, and the mass ratio of the film-forming agent A and film-forming agent B is (2-20):1; film-forming agent A is polyvinyl alcohol, and film-forming agent B is selected from at least one of acetate starch and hydroxyethyl cellulose.

[0010] Since polyvinyl alcohol is rich in hydroxyl groups, it has a strong affinity with starch acetate and hydroxyethyl cellulose. The inventors have found that physical blending of polyvinyl alcohol with starch acetate and hydroxyethyl cellulose within a certain proportion range can improve the moisture resistance of the cleaning tablets during daily storage. When combined with specific surfactants, the poor water solubility of the composite film of polyvinyl alcohol and other bio-based polymer compounds can be improved, and the film can be quickly dissolved during use.

[0011] Starch acetate is produced by the esterification reaction of starch under the action of acetic acid, and has high safety and biodegradability. Compared with ordinary starch, starch acetate has higher water dispersibility, heat resistance and film-forming property. As a film-forming agent for shampoo tablets, it can improve the moisture resistance of the product. In addition, the high water dispersibility can be stirred faster and more evenly during the slurry preparation process, thereby improving the preparation efficiency.

[0012] In some embodiments, the surfactant includes an amino acid surfactant, an anionic surfactant and a nonionic surfactant, and the mass ratio of the three is (10-35): (3-32): (1-10).

[0013] In some embodiments, the amino acid surfactant includes at least one of lauroyl glutamate, lauroyl sarcosinate, myristoyl glutamate, palmitoyl glutamate, and cocoyl glycinate.

[0014] Amino acid surfactants have the characteristics of mild performance, low irritation and good biodegradability, but they are easy to affect the viscosity of the product. The inventors found that when amino acid surfactants and anionic surfactants are mixed, the electrostatic interaction between them may cause the distance between molecules to increase, thereby reducing the viscosity of the system. Compared with liquid shampoo products, which can increase the viscosity of the product by adding thickeners, tablet shampoo products require the slurry to have an appropriate viscosity. If the viscosity is too low, it cannot be formed, or the forming speed is slow, resulting in the product being too dry and brittle; if the viscosity is too high, the feeding speed is slow during the film making process, and the slurry tails and cannot be formed into sheets.

[0015] In some embodiments, the anionic surfactant includes at least two of α-olefin sulfonate, fatty acid methyl ester sulfonate, and methyl lauroyl taurate.

[0016] In some embodiments, the nonionic surfactant includes at least one of alkyl glucoside, maltoside, and xylitol glucoside.

[0017] In some embodiments, the filler includes at least one of kaolin, bentonite, porous starch, cyclodextrin, and maltodextrin.

[0018] The specific filler selected by the present invention can not only assist in the molding of the shampoo tablet, but also absorb active substances such as hair conditioners and plant extracts to protect the active substances during the tablet making process; in addition, when used, the active substances can be released to absorb scalp and hair oil, thereby playing a role in cleaning the oil and dirt of the hair follicles and scalp.

[0019] In some embodiments, the hair conditioner includes at least one of allantoin, shea butter, coconut oil, hydrolyzed soy protein, hydrolyzed corn starch, and hydrolyzed wheat protein.

[0020] In some embodiments, the plant extract includes at least one of tea tree oil, Platycladus orientalis leaf extract, Camellia oleifera extract, and Sapindus mukorossi extract.

[0021] Natural plant extracts are green, non-toxic, mild, safe, and easily degradable. The present invention uses specific tea tree oil, perilla leaves, camellia oleifera, and soapberry, which are rich in saponins, volatile oils, fatty acids, and other active ingredients, so that the product has multiple effects such as anti-inflammatory, antibacterial, sterilization, antipruritic and anti-dandruff while maintaining cleaning power.

[0022] In some embodiments, the antibacterial agent includes at least one of colloidal sulfur, selenium disulfide and pyridone ethanolamine salt.

[0023] In some embodiments, the chelating agent includes at least one of citric acid and its salts, methylglycine diacetic acid and its salts, and glutamic acid diacetic acid and its salts.

[0024] In some embodiments, the auxiliary agent includes dimethylsiloxane and a polyol, and the polyol includes at least one of glycerol, propylene glycol, butylene glycol, hexylene glycol, caprylyl glycol, sorbitol, and mannitol.

[0025] The second aspect of the present invention provides a method for preparing an antibacterial cleaning tablet, comprising the following steps:

[0026] S1. The filler and the hair care agent, the plant extract and one-half the mass of deionized water are mixed at 25-35 ℃ to obtain a composition;

[0027] S2. Mix the film-forming agent with the remaining deionized water, raise the temperature to 75-85°C, and stir at a constant temperature until the material is swollen and fully dissolved, add a surfactant and a chelating agent, stir and dissolve evenly, then cool to 45-60°C, add the composition, stir evenly to obtain a slurry, dry, shape into sheets, slice, and obtain an antibacterial cleaning tablet.

[0028] The third aspect of the present invention provides an application of an antibacterial cleaning tablet, which is used for cleaning hair, hands and clothes.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] Traditional anti-dandruff components such as sulfur, selenium disulfide and pyridone ethanolamine salt have poor water solubility, anti-precipitation and dispersibility, and are easy to sink and stratify in shampoo, resulting in uneven distribution of anti-dandruff agents and excessive local concentration. At present, a large amount of thickener is usually added to shampoo to reduce fluidity to improve the above problems, but as the storage time increases, the anti-dandruff components eventually sink to the bottom. The innovative tablet washing and care products of the present invention can fundamentally solve the above problems. BRIEF DESCRIPTION OF THE DRAWINGS
