Description
Technical Field
The invention belongs to daily chemical detergents, and particularly relates to a laundry composition.
Background
The laundry detergent is a common article for washing and protecting clothes in daily life, and has the unique advantages of energy conservation, environmental protection, convenient use, quick dissolution, low alkalinity, mild property to fabrics and skin and the like. Laundry beads have been gradually introduced into the market since the 21 st century as a completely new form of fabric washing. The washing form wraps the detergent in the water-soluble film, and the whole detergent is thrown into the washing machine during washing, so that the detergent has the advantages of accurate dosage, convenience and quickness in use, reduction of unnecessary external packages, and environmental friendliness.
Whether laundry detergent or laundry beads, sudsing is an important aspect of consumer awareness of their detersive cleaning power. In the daily clothes washing process, consumers often judge whether the fabric is rinsed cleanly according to the amount of the foam. According to market research, consumers generally feel that much foam is generated when using the conventional laundry detergent or laundry beads, and the laundry detergent is difficult to rinse and clean, and sometimes the foam is too high during washing and overflows from the washing machine. The traditional laundry detergent has high surfactant content and less addition of other auxiliary agents, so that more foam is generated and the foam is difficult to rinse, water resources are wasted, the laundry cost is increased, large-scale water pollution is caused, and the traditional laundry detergent is not beneficial to energy conservation and emission reduction and green environmental protection.
The common method for solving the difficulty in rinsing liquid detergent in the industry is to adopt polyether surfactant or isomeric alcohol ether, and add fatty acid salt or organosilicon defoamer into the detergent to control foam. The laundry detergent mainly containing fatty alcohol-polyoxyethylene ether has good detergency, but has defoaming property which is not as good as that of the laundry detergent mainly containing heterogeneous alcohol ether, and the laundry detergent mainly containing heterogeneous alcohol ether has good defoaming property but has weaker detergency. Patent document 1 discloses a low-foam easy-to-rinse laundry detergent composition, which achieves a low-foam easy-to-rinse effect by compounding a saturated fatty acid soap and an unsaturated fatty acid soap. However, unsaturated fatty acids have low defoaming efficiency, and saturated fatty acids, although having high defoaming efficiency, tend to form calcium soaps in water, have poor solubility in water, and have a much lower adsorption rate at the gas-liquid interface than other surfactants, so that the phenomenon of excessive foam at the initial stage of machine washing may occur. Patent document 2 discloses a low-foaming easy-rinsing laundry detergent composition, which selects low-foaming main surfactants (AEO, MES), selects fatty acid soap for compounding to cooperatively remove dirt and rapidly promote foam rupture, uses 0.02-10% modified silicone oil defoamer, can diffuse in foam due to very low surface tension of modified dimethyl silicone oil, and the silicone oil active ingredient replaces the surfactant, so that a foam layer film becomes thin, and the foam becomes unstable and is easy to rupture. The organosilicon defoaming agent can be used for quickly defoaming, but the bleaching easiness of the laundry detergent cannot be improved, the scheme can only achieve 2 times of bleaching, and the stability of organosilicon in the laundry detergent is also a problem recognized in the industry. Patent document 3 discloses a concentrated detergent composition, which is prepared by compounding fatty alcohol EO/PO block polyether nonionic with a specific structure and saturated fatty acid soap according to a certain proportion, so that the problem of excessive foam in the initial washing stage of the concentrated laundry detergent is solved, but the low foam is not equal to the problem of one-time rinsing.
At present, in addition to the requirement of improving the property of easy rinsing, the traditional laundry detergent mostly has the function of removing visible dirt but does not have the function of bacteriostasis and sterilization, and the demand of providing the laundry detergent with antibacterial property also exists in consideration of the problems of environmental pollution, humidity in a washing machine and the like, and bacteria are easy to breed on clothes, so that the body health is influenced. Patent document 4 discloses a detergent composition for kitchen use, which is added with a quaternary ammonium salt cationic surfactant and has a strong antibacterial and disinfecting function, but the formula is not suitable for laundry detergent. Patent document 5 discloses an antibacterial laundry detergent comprising 0.1 to 1.0% of silver nanoparticles and a surfactant which is a mixture of an anionic surfactant and a nonionic surfactant.
Therefore, in the field of laundry detergent or laundry beads, it is an object of research and development to find a laundry composition which is stable in various properties of the Pinghu lake, such as primary rinsing, antibacterial property, normal temperature and low temperature, strong detergency, and environmental friendliness.

< laundry composition >
The invention provides a laundry composition comprising three nonionic surfactants and a fatty acid salt and a degerming agent.
In one embodiment, the composition comprises:
fatty alcohol polyoxyethylene polyoxypropylene ether: 5 to 80 wt%
Fatty acid methyl ester ethoxylate: 1 to 60 wt%
Fatty alcohol polyoxyethylene ether: 5 to 80 wt%
0.1-5 wt% of degerming agent
Fatty acid salts: 0.1 to 5 wt%
And a solvent.
Fatty alcohol polyoxyethylene polyoxypropylene ether (EO/PO ether) is a low-foaming nonionic surfactant. The EO group in the fatty alcohol EO/PO polyether nonionic is hydrophilic, the PO is hydrophobic, the hydrophilic group and the hydrophobic group block are more easily aggregated in water to form micelles or aggregated on a gas-liquid interface, on one hand, the surface tension of the gas-liquid interface is increased, so that the gas-liquid interface is unstable, on the other hand, the hydrophobic group and the hydrophilic group are staggered to generate steric hindrance, and a large number of gaps are generated in a liquid film, so that the liquid film is more easily broken. Fatty alcohol polyoxyethylene polyoxypropylene ethers are known in the industry to have low foaming properties, but in complex laundry composition systems, the polyoxyethylene polyoxypropylene ethers are only one of many surfactants, the problem of foaming of laundry detergent or laundry beads cannot be solved only by means of the surfactants, and in addition, the foaming problem cannot be solved by all the surfactants with EO/PO block polyether structures, the molecular HLB value, the EO number, the PO number and the carbon chain length influence the defoaming effect, and in addition, the low foaming effect is not equal to one-time rinsing. Low foaming means that the surfactant in the solution generates low foam under the action of force, and "one rinse" means that the foam can be rinsed clean by rinsing 1 time. Compared with surfactants such as fatty alcohol polyoxyethylene ether sodium sulfate AES, cocoamidopropyl amine oxide and the like, the polyoxyethylene polyoxypropylene ether has low foam, but the foam can be rinsed clean only by rinsing for many times because the polyoxyethylene polyoxypropylene ether cannot achieve the effect of rinsing for one time. In the invention, the inventor adopts a surfactant with a specific structure in the surfactants as a first nonionic surfactant to be matched with other two nonionic surfactants and fatty acid salt for solving the problem of realizing one-time rinsing while maintaining the detergency. In one embodiment, the fatty alcohol polyoxyethylene polyoxypropylene ether used in the present invention satisfies the general formula:

Further preferably, R1Is a saturated straight chain hydrocarbon group having 12 to 16 carbon atoms, m is 6 to 10, and n is 2 to 6. When M is not less than the lower limit, the liquid stability is more easily improved, and when M is not more than the upper limit, the detergency is more easily improved. When N is less than the upper limit, the liquid stability is more easily improved.
The addition amount of the fatty alcohol polyoxyethylene polyoxypropylene ether relative to the total mass of the composition is 5-80 wt%, preferably, the addition amount of the fatty alcohol polyoxyethylene polyoxypropylene ether relative to the total mass of the composition is 5-30 wt%, or the fatty alcohol polyoxyethylene polyoxypropylene ether accounts for 30-50% of the total addition amount of the three nonionic surfactants.

Further, R2Is a saturated straight chain or branched chain alkyl with 12-16 carbon atoms, a is 7-10, preferably AEO7 (average ethoxylation degree is 7) or AEO9 (average ethoxylation degree is 9) or isomeric alcohol ether TO-8 is used.
The addition amount of the fatty alcohol-polyoxyethylene ether relative to the total mass of the composition is 5-80 wt%, the fatty alcohol-polyoxyethylene ether mainly plays a cleaning role, poor detergency can be caused if the addition amount is too low, fluidity can be affected if the addition amount is too high, preferably, the addition amount of the fatty alcohol-polyoxyethylene ether relative to the total mass of the composition is 5-60 wt%, further 5-30 wt%, or the fatty alcohol-polyoxyethylene ether accounts for 15-50% of the total addition amount of the three nonionic surfactants. When the laundry composition is prepared into a laundry detergent, the preferable addition amount of the fatty alcohol-polyoxyethylene ether is 5-60 wt%, and further 5-30 wt%. When the laundry composition is prepared into a liquid composition in a laundry bead, the preferable addition amount of the fatty alcohol-polyoxyethylene ether is 10-60 wt%, and further 10-30 wt%. The fatty alcohol-polyoxyethylene ether may be a commercially available one, or may be prepared by adding a natural fatty alcohol or an isomeric alcohol to ethylene oxide by a known synthesis method. The second nonionic surfactant may be used alone in 1 kind, or in a combination of 2 or more kinds, and preferably used alone in 1 kind.
The third nonionic surfactant is a fatty acid methyl ester ethoxy compound (MEE for short), which is a novel double-end-capped ester ether type nonionic surfactant. MEE not only has similar performance with fatty alcohol polyoxyethylene ether (AEO), but also has the characteristics of cheap raw materials, low foam, high water-soluble speed, strong oil solubilization capacity, small skin irritation, good biodegradability and the like compared with the MEE. In one embodiment of the present invention, the fatty acid methyl ester ethoxylate used in the present invention satisfies the following general formula:
