Description
Technical Field
The invention relates to the field of daily chemical articles, in particular to an enzyme-containing laundry gel ball and a preparation method thereof.
Background
The working principle of the fabric washing liquid is similar to that of the traditional washing powder and soap, and the active ingredients are all surfactants. The difference lies in that: the traditional washing powder and soap generally adopt anionic surfactants, mainly comprising sodium alkyl sulfonate and sodium stearate, have stronger alkalinity (the pH value of the washing powder with standard dosage is generally more than 10 after being dissolved in water), and further have larger irritation and damage to the skin when in use. The pH of the laundry detergent is usually alkalescent and is about 8-10, the laundry detergent is nearly neutral (the pH is about 7-7.5) after being added into water, is milder to the skin, and is degraded faster than washing powder after being discharged into the nature, so the laundry detergent becomes a new generation detergent in recent years.
The active ingredients of the laundry detergent are mainly nonionic surfactants, and the structure of the laundry detergent comprises a hydrophilic end and an oleophilic end, wherein the oleophilic end is combined with stains, and then the stains and fabrics are separated by physical movement (such as hand rubbing and machine movement). Meanwhile, the surfactant reduces the tension of water, so that the water can reach the surface of the fabric, and the effective components can play a role.
However, the existing laundry detergent contains a large amount of water (generally 50-80%), so that the content of the main active ingredient surfactant is not high (generally below 40%), which makes the volume of the common laundry detergent larger, and at least 50% of the volume is ineffective. This puts a certain pressure on the transportation and storage space of the laundry detergent product. Meanwhile, the laundry detergent needing to be contained in the container is not convenient enough when in use. If the concentration of the laundry detergent is increased, the stability of the product is poor, and phenomena such as layering, turbidity, deposition and the like are easy to occur.
Disclosure of Invention
In order to solve the technical problems, the invention provides an enzyme-containing laundry gel ball and a preparation method thereof. The invention injects the waterless washing liquid into the water-soluble outer gel film layer to prepare the gel ball shape. The washing liquid takes polyethylene glycol as a solvent and contains no moisture, so that the content of the surfactant is greatly improved, the volume is effectively saved, and the washing product is convenient to store and transport. Meanwhile, the spherical product is convenient to use and can be directly thrown into water.
The specific technical scheme of the invention is as follows: an enzyme-containing laundry gel ball comprises a water-soluble outer gel film layer and an anhydrous washing solution hermetically wrapped by the outer gel film layer; the anhydrous washing liquid comprises the following components in parts by weight:
40-60 parts of non-ionic surfactant,
0 to 20 parts of amphoteric surfactant,
1-5 parts of polymer-coated enzyme preparation,
1-5 parts of a seaweed concentrated solution,
0.5 to 10 portions of washing assistant,
10-30 parts of polyethylene glycol.
The invention has the technical effects that:
1. the invention injects the waterless washing liquid into the water-soluble outer gel film layer to prepare the gel ball shape. The washing liquid takes polyethylene glycol as a solvent and contains no moisture, so that the content of the surfactant is greatly improved, the volume is effectively saved (about half of the volume can be reduced), and the washing product is convenient to store and transport. Meanwhile, the spherical product is convenient to use and can be directly thrown into water. In addition, the polyethylene glycol can be used as a solvent, and has the effects of softening clothes and resisting static electricity, so that corresponding washing aids can be omitted or reduced.
2. In recent years, a large number of enzyme-containing laundry detergents have appeared on the market, but the enzymatic activity of the enzyme preparation is subject to many factors, such as pH, temperature, inhibition of other auxiliaries, etc. Particularly, after the enzyme preparation is prepared into the laundry detergent, the enzyme preparation is easily influenced by factors such as storage temperature, inhibition of other reagents in the laundry detergent and the like, the enzyme preparation is easily inactivated in advance and is not easy to store, and in addition, the enzyme preparation is also easily precipitated due to long-time standing in the storage process, so that the dispersibility of the enzyme preparation in the laundry detergent is poor.
The washing liquid contains the polymer-coated enzyme preparation, and the enzyme preparation is protected under the coating of the polymer, is not easily influenced and inhibited by temperature and other reagents in a formula in the storage process, and can always keep higher enzyme activity. In particular, the polymers for coating enzymes of the invention have a specific pH sensitivity which the inventors have tailored to the wash liquor system of the invention: when the polymer is in a strong alkaline water environment (pH is more than 8) or an anhydrous environment, two ends of a polymer molecular chain are folded, so that the enzyme can be tightly wrapped, the enzyme is protected, and the influence of the outside on the enzyme activity is reduced, so that the enzyme is not easy to inactivate when the washing liquid is stored. When the polymer is in water with pH 7-7.5 (water added with washing liquid during washing), the polymer molecular chain can be stretched and straightened, and the enzyme is quickly released into the water, so that the polymer can exert the effect.
As mentioned above, in the prior art, the enzyme preparation is easy to settle due to the standing of the washing liquid for a long time during storage, so that the dispersibility of the enzyme preparation in the washing liquid is poor, and the enzyme-containing washing liquid products on the market are few. For this reason, the invention makes two improvements: 1. the seaweed concentrated solution is added into the formula and is a viscous liquid, a small amount of three-dimensional space network structures can be formed in the washing liquid after the seaweed concentrated solution is added with proper content, and the enzyme preparations are locked in small grids one by one, so that the steric hindrance is increased, and the seaweed concentrated solution is difficult to settle and accumulate. 2. After the polymer coated with the enzyme is compounded with the seaweed concentrated solution, the polymer can also be synergized with the seaweed concentrated solution to form a three-dimensional network structure, so that the steric hindrance is further increased. In addition, as the molecular chain of the polymer is stretched and straightened when clothes are washed (pH is 7-7.5), all groups on the molecular chain are exposed, the groups can also play a role in preventing secondary deposition of dirt particles, and have a certain anti-deposition effect without additionally adding auxiliary agents such as an anti-deposition agent, and the like, thereby achieving multiple purposes.
Preferably, the particle size of the enzyme-containing laundry gel ball is 0.5-5 cm.
Preferably, the outer gel film layer is selected from carrageenan, gelatin, polyvinyl alcohol resin or carbomer.
The water-soluble outer gel film layer can be dissolved in water at a proper temperature when being put into clothes for washing, and is convenient to use. The material also has certain strength and is not easy to break when stored.
Preferably, the concentration of the concentrated seaweed solution is 60-80 wt%.
Preferably, the nonionic surfactant is selected from at least one of fatty alcohol-polyoxyethylene ether, ethoxylated fatty acid ester, alkanolamide and alkyl glycoside; the amphoteric surfactant is selected from at least one of cocamidopropyl betaine and dodecyl dimethyl amine ethyl lactone; the washing assistant is at least one selected from whitening agent, softening agent, essence, pigment, preservative and dye-proofing agent.
Preferably, the polymer-coated enzyme preparation is a complex enzyme coated by a polymer.
Preferably, the complex enzyme is selected from at least two of alkaline protease, alkaline lipase, amylase and cellulase.
Preferably, the preparation method of the polymer-coated enzyme preparation comprises the following steps:
A) mixing 100 parts of caprolactone, 2-4 parts of benzyl alcohol and 1-2 parts of stannous octoate, reacting for 8-12h at the temperature of 120-; dissolving 10 parts of hydroxyl-terminated modified polycaprolactone in chloroform, sequentially adding 0.5-1 part of 2- (dodecyl trithiocarbonate) -2-methylpropanoic acid and 0.5-1 part of N-hydroxysuccinimide/dicyclohexylcarbodiimide, fully reacting, filtering, and precipitating filtrate with anhydrous methanol to obtain a polycaprolactone initiator;
B) mixing 100 parts of lactide with 1-2 parts of benzyl alcohol and 0.5-1 part of stannous octoate, reacting for 8-12h at the temperature of 120-;
C) dissolving 1 part of polycaprolactone initiator in dimethyl sulfoxide, adding 0.01-0.05 part of azobisisobutyronitrile, adding 1-3 parts of histidine, and polymerizing at 55-65 ℃ for 4-8 h; then adding 0.5-1.5 parts of hydroxyl-terminated modified polylactic acid, carrying out thermal insulation polymerization for 6-10h, and precipitating the reaction solution by using n-hexane to obtain a polymer;
D) dispersing 10 parts of polymer in deionized water, adjusting the pH value to 6-7.5, adding 5-15 parts of complex enzyme, stirring and heating to 30-40 ℃, ultrasonically dispersing uniformly, standing and adsorbing for 2-6h, adjusting the pH value to be more than 8, and dialyzing to obtain the polymer-coated enzyme preparation.
The parts of the above substances are all parts by weight.
The molecular main chain of the polymer has a triblock structure, namely polycaprolactone, histidine and polylactic acid, and the polymer formed by the triblock structure has the following characteristics: when the polymer is in a strong alkaline water environment (pH is more than 8) or an anhydrous environment, the middle block of the polymer is positively charged (the isoelectric point of histidine is about 7.6), and the blocks at two ends of the polymer are negatively charged. When the polymer is in water with the pH value of 7-7.5 (water added with washing liquid during washing), three blocks on the molecular chain of the polymer are all positively charged, and due to the principle that like poles repel each other, the molecular chain can stretch and straighten, so that enzyme is quickly released into the water to exert the effect. The polymers are specifically designed according to the invention for the washing liquor system according to the invention and do not belong to the prior art.
In addition, it should be noted that, since the polymer of the present invention can change the structure under different pH environments, the present invention particularly does not add an anionic surfactant having a certain influence thereon and does not add or little add an amphoteric surfactant, but mainly adds a nonionic surfactant.
Preferably, the molecular weight of the polymer is 8-12 w; the particle size of the polymer coated enzyme preparation is 100-500 nm.
The particle size of the enzyme is in the range of several tens of nanometers, and therefore the molecular weight of the polymer needs to be designed to the above reasonable extent so as to be able to better achieve the coating of the enzyme.
A preparation method of enzyme-containing laundry gel balls comprises the following steps:
1) adding a nonionic surfactant, an amphoteric surfactant and a seaweed concentrated solution into polyethylene glycol according to a ratio, and heating and stirring uniformly to obtain a viscous solution;
2) adding a washing assistant into the viscous solution, heating and stirring uniformly, then adding a polymer coated enzyme preparation, and stirring uniformly to obtain an anhydrous washing solution;
3) and (4) injecting the anhydrous washing liquid into the spherical outer gel membrane layer, and sealing to obtain a finished product.
Compared with the prior art, the invention has the beneficial effects that:
1. the invention injects the waterless washing liquid into the water-soluble outer gel film layer to prepare the gel ball shape. The washing liquid takes polyethylene glycol as a solvent and contains no moisture, so that the content of the surfactant is greatly improved, the volume is effectively saved, and the washing product is convenient to store and transport. Meanwhile, the spherical product is convenient to use and can be directly thrown into water.
2. The washing liquid contains the polymer-coated enzyme preparation, and the enzyme preparation is not easily influenced and inhibited by temperature and other reagents in a formula in the storage process under the condition of polymer coating, so that higher enzyme activity can be always kept. And at the same time the polymer coated enzyme preparation is not prone to sedimentation in laundry detergents.

| Example 3 | Non-layering, clarifying and transparent | Without obvious settlement |
| Example 4 | Non-layering, clarifying and transparent | Without obvious settlement |
| Comparative example 1 | Delamination, haze, poor transparency | The bottom layer has obvious settlement |
| Comparative example 2 | No delamination and slight turbidity | The bottom layer has obvious settlement |
From the comparison of the data, it is clear that the washing liquid of the present invention is not easily delaminated and the enzyme preparation is not easily precipitated even if the surfactant is contained at a high concentration, whereas the aqueous laundry liquid of comparative example 1 is easily delaminated and turbid and the enzyme preparation is easily precipitated due to the excessively high surfactant. In contrast, in comparative example 2, the precipitation of the enzyme preparation could not be effectively avoided because no seaweed concentrate was added, which indicates that the precipitation could be effectively avoided only in the case of combining the seaweed concentrate with the polymer.
The washing solutions of examples 1 to 4 and comparative examples 1 to 2 were subjected to a high and low temperature stability test: the product was observed for steady state and the results were as follows:
as is clear from the comparison of the above data, the enzyme preparation in the washing liquid of the present invention is less likely to settle.
In addition, the washing powder in examples 1-4 also contains a reduction whitening agent, wherein various metal ions are dispersed in the reduction whitening agent, and a galvanic cell effect can be formed in a water environment (after the washing powder is put into water) due to the potential difference of various metals; and hydrogen loaded in the reduction whitening agent is matched, so that the reduction whitening agent has strong reducibility, can reduce the oxidized and yellow fabric to restore the original white color, and has a good whitening effect.
In the preparation process, in the step A), a first solution containing hydrogen, magnesium and zinc ions is prepared; when the second solution is prepared, the activity of copper is lower than that of hydrogen, and the copper cannot directly react with hydrogen peroxide. In step B), the two solutions are mixed, and bentonite having excellent adsorptivity and cation exchange capacity capable of successfully supporting thereon metal ions in the solution and a small amount of hydrogen gas is added. In step C), the reduction whitening powder is further loaded on the polyurethane foam liquid, and after further curing and drying, porous hard foam particles loaded with the reduction whitening powder, namely the reduction whitening agent, are formed.
The raw materials and equipment used in the invention are common raw materials and equipment in the field if not specified; the methods used in the present invention are conventional in the art unless otherwise specified.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
