In one embodiment, the raw materials of the multifunctional cleaning agent for removing oil and inhibiting bacteria further comprise 0.25-0.35 parts by weight of essence.
In a preferred embodiment, the raw material of the multifunctional oil-removing and bacteriostatic cleaning agent further comprises 3-4 parts by weight of an organic solvent.

In a more preferred embodiment, the weight ratio of builder to anionic surfactant is 1: 0.75.
anionic surfactants
In one embodiment, the anionic surfactant comprises alkyl benzene sulfonate.
Most stains are adhered to the surface of a carrier in a liquid form at present, such as silk fabrics and kitchen tableware, the main stains are greasy dirt in the using process, sodium alkyl benzene sulfonate is used in the largest amount in washing, the sodium alkyl benzene sulfonate has good foaming property and detergency, and has a remarkable detergency effect on granular dirt, protein dirt and oily dirt, but the detergency of the alkyl benzene sulfonate is increased along with the increase of the washing stability, and the effect is relatively poor when the sodium alkyl benzene sulfonate is used for cleaning at normal temperature, particularly heavy greasy dirt.
In a preferred embodiment, the alkylbenzene sulfonate is a C10 to C14 alkylbenzene sulfonate and/or a C3 to C5 alkylbenzene sulfonate.
In a more preferred embodiment, the alkylbenzene sulfonate is a mixture of C10-C14 alkylbenzene sulfonate and C3-C5 alkylbenzene sulfonate, and the weight ratio of C10-C14 alkylbenzene sulfonate to C3-C5 alkylbenzene sulfonate is (2-4): 1.
the applicant finds that by using alkylbenzene sulfonates with different chain lengths, compared with the alkylbenzene sulfonates with C10-C14, the alkylbenzene sulfonates with C10-C14, which have higher lipophilicity, have better penetrating effect on the greasy dirt on the surface of the carrier, and the alkylbenzene sulfonates with C3-C5, which have higher hydrophilicity, have better wetting effect on the carrier-water interface, because the alkylbenzene sulfonates with different chain lengths have similar structures, the alkylbenzene sulfonates with short chain length can promote the long-chain alkylbenzene sulfonates to better contact with the dirt and promote the separation of the dirt and the carrier, and because the alkylbenzene sulfonates with short chain length have hydrophilic effect, the separated dirt can be dispersed in the aqueous solution of the cleaning agent, and the cleaning rate of the heavy oil can be improved. The applicant has found that in the system of the present invention, the weight ratio of alkyl benzene sulfonate with different chain lengths needs to be ensured, and when the amount of alkyl benzene sulfonate with short chain is large, the cleaning effect of the cleaning agent is poor, probably because the increase of the alkyl benzene sulfonate with short chain is not beneficial to the separation of oil stain and carrier.
In a more preferred embodiment, the C10-C14 alkylbenzene sulfonate may be sodium dodecylbenzene sulfonate, sodium undecylbenzene sulfonate, sodium dodecylbenzene sulfonate, sodium tridecylbenzene sulfonate, sodium tetradecylbenzene sulfonate, potassium dodecylbenzene sulfonate, potassium undecylbenzene sulfonate, potassium dodecylbenzene sulfonate, potassium tridecylbenzene sulfonate, potassium tetradecylbenzene sulfonate, or the like; and C3-C5 alkylbenzene sulfonate can be sodium cumene sulfonate, sodium butyl benzene sulfonate, potassium cumene sulfonate, potassium butyl benzene sulfonate, etc.
In this embodiment, the C10-C14 alkylbenzene sulfonate is sodium dodecylbenzene sulfonate, and the C3-C5 alkylbenzene sulfonate is sodium cumene sulfonate.
The sodium dodecyl benzene sulfonate is Panoclastf-90; sodium cumene sulfonate is US Hensman STEPANATE SCS-40.
In a more preferred embodiment, the anionic surfactant further comprises a fatty alcohol polyether sulfate.
The applicant has found that when alkylbenzene sulfonate is used as an anionic surfactant and an alkanolamine builder, the lipophilicity and wettability are increased, and the penetration of the alkylbenzene sulfonate into oil stains and the like at normal temperature is promoted, and the separation of the oil stains from the surface of a carrier is promoted, but the increase in lipophilicity of the alkylbenzene sulfonate, particularly long-chain alkylbenzene sulfonate, also causes stains detached from the surface of the carrier to be reattached to the surface of the carrier, and even causes the alkylbenzene sulfonate and the like to be attached to the surface of the carrier, so that the cleaning effect is affected, and the cleaning agent remaining on the surface of the carrier may be harmful, and needs to be washed off as soon as. The applicant finds that the cleaning effect and the bactericidal performance of the cleaning agent can be improved by adding the fatty alcohol polyether sulfate, probably because the dispersion of oil stains acted by the alkylbenzene sulfonate in the aqueous solution of the cleaning agent is promoted due to the action of sulfate and polyether structures in the fatty alcohol polyether sulfate. Meanwhile, the applicant also finds that compared with fatty alcohol sulfate, the cleaning agent has a better cleaning rate on normal-temperature heavy oil stains.
In a more preferred embodiment, the weight ratio of fatty alcohol polyether sulfate salt to alkylbenzene sulfonate is 1: (0.8 to 1).
The applicant has found that when the weight ratio of fatty alcohol polyether sulphate to alkylbenzene sulphonate is 1: (0.8-1), the cleaning rate and the rinsing performance of the cleaning agent are optimal simultaneously, and when the weight ratio of the fatty alcohol polyether sulfate salt to the alkylbenzene sulfonate is more than 1: at 0.8, the cleaning rate of the cleaning agent is reduced, and when the weight ratio of the fatty alcohol polyether sulfate salt to the alkylbenzene sulfonate is less than 1: when 1, the rinsing performance of the cleaning agent is reduced, probably because the amount of the fatty alcohol polyether sulfate salt is too much or too little, so that the synergistic effect of the fatty alcohol polyether sulfate salt and the alkylbenzene sulfonate is reduced, and the cleaning rate and the rinsing performance of the cleaning agent are influenced.
In a more preferred embodiment, the fatty alcohol polyether sulfate is a C12-C15 fatty alcohol polyether sulfate.
The applicant finds that in the system of the invention, when the fatty alcohol polyether sulfate is C12-C15 fatty alcohol polyether sulfate, the cleaning agent has better cleaning rate to heavy oil stains at normal temperature, probably because the long-chain alkyl in the C12-C15 fatty alcohol polyether sulfate is similar to the long-chain alkyl in the C10-C14 alkylbenzene sulfonate in structure and is easier to intertwine with each other, and probably because the C12-C15 fatty alcohol polyether sulfate can promote the penetration of the oil stains on the surface of a carrier.
In the embodiment, the C12-C15 fatty alcohol polyether sulfate is sodium laureth sulfate.
The sodium laureth sulfate was purchased from Shanghai Yichuan chemical science and technology Co., Ltd.
Builder
In one embodiment, the builder is an alcamine builder.
The applicant finds that after the alcohol amine builder is added into the system, the cleaning agent disclosed by the invention has a good cleaning effect on heavy oil stains at normal temperature. Probably, the nitrogen atom on the alcohol amine builder can be coordinated with alkyl benzene sulfonate ions, so that one side of a sulfonate group in partial alkyl benzene sulfonate is combined with monoethanolamine, the end part of long-chain alkyl benzene sulfonate is provided with an ethanol group and shows certain nonionic property, compared with a completely ionized sulfonate anion structure, the lipophilicity is further improved, the penetration of oil stains and the like is promoted, and the combined ethanol hydroxyl is also beneficial to the wetting of an interface.
In a preferred embodiment, the alkanolamine builder is selected from one or more of monoethanolamine, diethanolamine, triethanolamine, monopropanolamine.
In a more preferred embodiment, the amine builder is monoethanolamine.
The monoethanolamine is the Dow monoethanolamine.
The applicant finds that in the system of the present invention, when amine builder such as ethylamine, isopropylamine or the like, triethanolamine or the like is used, the cleaning effect on normal temperature heavy oil stains is poor, while when monoethanolamine is used, the cleaning effect on normal temperature heavy oil stains is optimal, which is probably because the combination of amine builder such as ethylamine, isopropylamine or the like, triethanolamine or the like, and alkylbenzene sulfonate is weak, which affects the cleaning effect of the prepared cleaning agent on normal temperature oil stains.
Bactericide
In one embodiment, the biocide is a quaternary ammonium salt biocide.
The applicant finds that when the bactericide in the system is the quaternary ammonium salt bactericide, the cleaning agent not only has good bactericidal performance, but also has better normal-temperature heavy oil cleaning effect and rinsing performance. The reason is probably that the cationic quaternary ammonium salt bactericide and the anionic surfactant can be closely arranged in an oriented manner on the alkyl chain on the surface of the detergent solution, so that the average area of the surfactant and the bactericide is reduced, the penetration of stains is promoted, the stains separated from the surface of the carrier and part of alkylbenzene sulfonate-alcohol amine are prevented from being re-attached to the surface of the carrier by the oriented alkyl chain, and the components in the detergent can be quickly driven to be dispersed in the water phase in the water rinsing process due to the interaction of the fatty alcohol polyether sulfate salt, the alkylbenzene sulfonate and the quaternary ammonium salt bactericide in a certain weight ratio, so that the residue on the surface of the carrier is avoided.
The applicants have also found that when the quaternary ammonium salt bactericide is less, it may have an effect on the alignment structure or the dispersion of the components of the cleaning agent during rinsing, and when the quaternary ammonium salt bactericide is too much, it may cause an increase in the surface residue of the carrier.
In a preferred embodiment, the quaternary ammonium salt bactericide is selected from the group consisting of dodecyltrimethylammonium chloride, dodecyldimethylbenzylammonium bromide, cyanoquaternary ammonium salts, di-C alkyl quaternary ammonium bromide salts, and one of polyazacycloquaternary ammonium salts, polyquaternary ammonium salts, and diquaternary ammonium salts.
In a more preferred embodiment, the quaternary ammonium salt germicide is dodecyl dimethyl benzyl ammonium chloride.
The dodecyl dimethyl benzyl ammonium chloride was purchased from Shandong Fuster chemical Co., Ltd.
The applicant finds that when the quaternary ammonium salt bactericide is dodecyl dimethyl benzyl ammonium chloride in the system, the bactericidal property, the rinsing property and the cleaning rate of the cleaning agent are better, probably because long-chain alkyl in the dodecyl dimethyl benzyl ammonium chloride is easier to intertwine with long-chain alkyl in C10-C14 alkylbenzene sulfonate and C12-C15 fatty alcohol polyether sulfate, alkyl chains in the system can be arranged in a tighter and oriented way, and meanwhile, benzyl in the dodecyl dimethyl benzyl ammonium chloride interacts with other raw materials in the system, so that the dodecyl dimethyl benzyl ammonium chloride can stably exist in the system.
Organic solvent
In one embodiment, the organic solvent is an alcohol ether based solvent.
In a preferred embodiment, the alcohol ether solvent is at least one selected from the group consisting of dipropylene glycol propyl ether, dipropylene glycol butyl ether, tripropylene glycol methyl ether, tripropylene glycol butyl ether, diethylene glycol butyl ether, propylene glycol butyl ether, and diethylene glycol hexyl ether.
The applicant finds that by adding alcohol ether as an organic solvent in the system, the stability of the cleaning agent under different temperature conditions of high temperature and low temperature can be improved, the rapid rinsing is facilitated, and stains and residues of cleaning agent components in the surface of the carrier are reduced. This is probably because the alcohol ether contains hydrophilic hydroxyl groups and ether bonds, and the alkyl group in the alcohol ether can be in contact with the alkyl group of an anionic surfactant or the like while having good compatibility with water, thereby promoting the stability of the anionic surfactant or the like in an aqueous solution.
In a preferred embodiment, the alcohol ether solvent is a mixture of butyl diethylene glycol monobutyl ether and butyl propylene glycol, and the weight ratio of the butyl diethylene glycol monobutyl ether to the butyl propylene glycol monobutyl ether is (1.6-2.2): (1.3-1.8).
The diethylene glycol butyl ether is Dow's diethylene glycol butyl ether; the propylene glycol butyl ether is the propylene glycol butyl ether of dekahm.
The applicant has found that when the carbon number of the alcohol ether is too small, the alcohol ether is mainly located in the aqueous solution of the cleaning agent, and when the carbon number of the alcohol ether is too large, the hydrophobic effect is too strong, which is not beneficial to improving the effects of the micelle and the water, and even influences the stability and the quick rinsing performance of the cleaning agent. The addition of alcohol ether with a certain carbon atom number, such as propylene glycol butyl ether and diethylene glycol butyl ether, is beneficial to entering between a fence layer of a micelle formed by a surfactant and the like and a solution, exerts good water solubility of the alcohol ether, further reduces the interfacial tension between oil and water, and promotes the dispersion and compatibility of the micelle in the aqueous solution.
Inorganic base
In the present invention, the inorganic base is not limited, and the inorganic base suitable for adjusting the pH value of the cleaning agent is suitable for the system of the present invention, for example, the inorganic base may be one or more of sodium hydroxide, potassium hydroxide, sodium bicarbonate, and sodium carbonate.
In this embodiment, the inorganic base is sodium hydroxide.
In the system of the present invention, the pH of the system can be adjusted using sodium hydroxide.

In the present invention, the essence is not limited, and the essence suitable for use in the cleaning agent is used in the system of the present invention. For example, the essence may be lemon black tea, lemon black tea essence, apple essence, orange essence, banana essence, and the like.
In this embodiment, the essence is lemon black tea essence.
Water (W)
In the present invention, the water is not limited, and the water may be tap water, distilled water, deionized water, or the like.
In the present embodiment, the water is tap water.
The second aspect of the invention provides a preparation method of an oil-removing bacteriostatic multifunctional cleaning agent, which comprises the following steps: the raw materials of the oil-removing and bacteriostatic multifunctional cleaning agent are uniformly mixed to obtain the oil-removing and bacteriostatic multifunctional cleaning agent.
In the present invention: the applicant finds that by using alkylbenzene sulfonate and fatty alcohol polyether sulfate as anionic surfactants and adding alcohol amine as a builder, the coordination effect between the alcohol amine and the anionic surfactants is utilized to increase the penetration and dispersion effect of cleaning agent components on stains on the surface of a carrier, various structures such as wax, fat and grease can be saponified and decomposed, so that the stains are separated from the carrier and are dispersed and suspended in a cleaning agent solution, and by controlling the using amounts and types of the anionic surfactants, the alcohol amine, a bactericide, alcohol ether and the like, secondary dirt is prevented from being generated, a small amount of cleaning agent components with strong lipophilicity are remained on the surfaces of the stains in the process of rinsing with water, the quick rinsing performance is improved, and the stability of a cleaning agent system is improved. And the propylene glycol butyl ether is a green environment-friendly high-grade solvent, has an excellent dissolving effect on heavy oil dirt, and is cooperated with dodecyl benzene sulfonic acid, sodium laureth sulfate, sodium isopropylbenzenesulfonate and the like in a diethylene glycol butyl ether synergistic system, so that the surface of a cleaned object is not easily stained with oil dirt, the cleaning period is shortened, and the cleaning is easy and quick.
