Description

Technical Field

[0001] The invention relates to the technical field of daily chemical products, in particular to a natural antibacterial detergent added with citrus plant extracts. Background Art

[0002] Daily chemical products refer to some chemical products used in people's daily lives, including shower gel, cosmetics, shampoo, laundry detergent, soap, detergent and so on.

[0003] As people's living standards continue to improve, people's awareness of cleaning and disinfection of tableware, kitchen utensils, vegetables, fruits and other items is also constantly increasing. If they are washed directly with clean water, the cleaning effect is poor. With the advent of detergents, more and more detergents are used to clean these items.

[0004] At present, most dishwashing liquids use petroleum-derived products sodium alkylbenzene sulfonate (LAS) and fatty alcohol polyoxyethylene sulfate (AES) as the main foaming and cleaning ingredients. These two surfactants are easily soluble in water, are inexpensive, and have good washing performance and are widely used. As dishwashing liquids are endowed with various properties, they are widely used in the catering industry.

[0005] With the development of the detergent industry, detergents are becoming more and more natural and environmentally friendly. Traditional detergents are mainly used to clean dirt on the surface of tableware, but have limited inhibitory effects on bacteria.

[0006] Based on this, we proposed a natural antibacterial detergent with added citrus plant extracts, hoping to solve the shortcomings of the existing technology. Summary of the invention

[0007] 1. Technical issues to be solved

[0008] In view of the deficiencies in the prior art, the present invention provides a natural antibacterial detergent added with citrus plant extracts.

[0009] (II) Technical solution

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0011] A natural antibacterial detergent with citrus plant extracts added, comprising the following ingredients by weight percentage:

[0012] Plant extract 1%-5%, surfactant 15-35%, gelling agent 0.5-1.5%, food preservative 0.01-0.2%, auxiliary agent 0.3-0.5%, the balance is deionized water;

[0013] The plant extract is a citrus plant extract.

[0014] As a further technical solution, the preparation method of the citrus plant extract is:

[0015] (1) Pretreatment: First, wash, dry and grind the citrus peel through a 40-mesh sieve;

[0016] Weigh 5 g of citrus peel powder and dissolve it in 200 ml of 95% ethanol, then ultrasonically treat it for 30 minutes to obtain a pretreated mixture;

[0017] (2) Extraction preparation: The pretreated mixture was kept in an oil bath at 70°C for 2 h to obtain a crude ethanol extract of citrus plants;

[0018] (3) Concentration: The crude ethanol extract of citrus plants is subjected to vacuum filtration to remove solid particles, and then the remaining liquid is subjected to rotary evaporation to recover the ethanol to obtain the citrus plant extract.

[0019] As a further technical solution, the citrus plant peel in step (1) is a mixture of the peels of cocktail grapefruit, golden pomelo, and kumquat;

[0020] Among them, the mixed mass ratio of cocktail grapefruit peel, golden pomelo peel and kumquat peel is 3:1:5.

[0021] As a further technical solution: the surfactant is a composition consisting of: coconut oil foaming agent (CAB-35), coconut oil diethanolamide (6501), sodium polyoxyethylene lauryl ether sulfate (AES), C8-C10 fatty alcohol polyoxyethylene ether (AEO-9) and polyethylene glycol octyl phenyl ether (OP-10 emulsifier), and the weight ratio of the above components in the surfactant is 3:2:8:2:2.

[0022] As a further technical solution, the gelling agent is alginate.

[0023] As a further technical solution, the food preservative is any one of sorbic acid, potassium sorbate, benzyl alcohol, sodium benzoate, and imidazolidinyl urea.

[0024] As a further technical solution: the preparation method of the auxiliary agent is:

[0025] First, curcumin is added to N,N-dimethylformamide, stirred at a speed of 500 r / min for 30 minutes, and then dicyclohexylcarbodiimide and 4-dimethylaminopyridine are added, and the temperature is cooled to below 6° C. in an ice bath, and then ferulic acid is added, and the stirring reaction is continued for 2 hours, and then filtered to obtain a crude product, and the crude product is eluted with ethyl acetate-petroleum ether, and then separated and purified by column chromatography;

[0026] Among them, the volume ratio of ethyl acetate to petroleum ether is 1:1.

[0027] As a further technical solution: the mixing ratio of curcumin and N,N-dimethylformamide is 2.34 g:40 mL;

[0028] The mixing ratio of curcumin, dicyclohexylcarbodiimide, 4-dimethylaminopyridine and ferulic acid is 2.34 g: 2.86 g: 0.154 g: 2.46 g.

[0029] As a further technical solution: the preparation method of the natural antibacterial detergent is:

[0030] (1) heating deionized water to 50-60° C., and then adding surfactants thereto, in the order of coconut oil foaming agent (CAB-35), coconut oil diethanolamide (6501), sodium polyoxyethylene lauryl ether sulfate (AES), C8-C10 fatty alcohol polyoxyethylene ether (AEO-9) and polyethylene glycol octylphenyl ether (OP-10 emulsifier), and stirring thoroughly to dissolve the above components;

[0031] (2) cooling the solution to 45° C., adding the citrus plant extract to the solution, and stirring thoroughly to dissolve the components;

[0032] (3) Cooling the mixture to below 40° C., adding food preservatives and additives, stirring to dissolve evenly, then adding a gelling agent to adjust the viscosity of the solution, and mixing evenly to obtain the product.

[0033] (III) Beneficial effects

[0034] Compared with the prior art, the present invention provides a natural antibacterial detergent with citrus plant extracts added, which has the following beneficial effects:

[0035] The surfactants used in the natural antibacterial detergent formula of citrus extracts prepared by the present invention are all green surfactants, with excellent biodegradability, environmental protection and pollution-free, and the various components show good compatibility and synergy to ensure the quality, stability and effect of the detergent. At the same time, it is easy to rinse clean, mild and non-irritating, safe and non-toxic.

[0036] The natural antibacterial detergent with citrus plant extract added prepared by the preparation method provided by the present invention can improve the antibacterial ability of washing products on the one hand; on the other hand, it can meet the high market demand for green, natural, and environmentally friendly washing products, and can simultaneously meet people's needs for cleaning and hygiene.

[0037] The present invention introduces citrus plant extracts into dishwashing liquid, which has strong antibacterial activity and can greatly improve the antibacterial performance of the dishwashing liquid. The antibacterial mechanism is mainly to achieve the antibacterial purpose by inhibiting the synthesis of bacterial cell walls. Since the main structural component of the bacterial cell wall is the cell wall mucopeptide, the formation of the intracytoplasmic mucopeptide precursor can be hindered by the active ingredients in the citrus plant extract, and the mucopeptide synthesis process at the cytoplasmic membrane stage will also be destroyed, thereby preventing the synthesis of the bacterial cell wall and achieving the purpose of efficient antibacterial.

[0038] The detergent prepared by the present invention can also be used to wash fruits, vegetables, etc., and has excellent decontamination ability. After washing, it can be rinsed with clean water without residue. Compared with ordinary detergents, the residue is higher after washing, which has a great advantage. The detergent prepared by the present invention has a broad-spectrum and strong antibacterial effect, and has a high antibacterial effect on a variety of bacterial microorganisms.

[0039] The invention optimizes the ingredients and cooperates with each other to make the prepared detergent milder, less irritating to the skin and capable of well protecting the safety of the hand skin. BRIEF DESCRIPTION OF THE DRAWINGS
