Technical Field

The invention relates to the technical field of daily chemical articles, in particular to an antibacterial laundry detergent and a preparation method thereof.

Background

Along with the improvement of the living standard of residents, along with the increasing importance of the society and consumers on health, cleanness and sanitation, the clothes are not cleaned by a pure decontamination effect any more, and more consumers are aware of whether the laundry product can achieve the effects of sterilization and disinfection. The prevention consciousness of the public is improved, so that the frequency of using the product is high, and the safety factor of the product to the human body is put to the first place.

The main circulated bacteriostatic laundry detergent in the current market plays a bacteriostatic and disinfectant role mainly in two forms, one is a disinfectant product mainly made of alcohol, the concentration of the disinfectant product is 75%, and the product has the advantages of low raw material price and low single-product sale price. The disadvantages are that it is not easy to circulate, carry, not sprinkle in air, in clothes, flammable and not recommended to be in direct contact with the skin of the body. The second is chlorine-centered, chlorine dioxide, hypochlorous acid, etc., which are used only occasionally at low concentrations without any problem, but when the concentrations of hypochlorous acid are added after long-term use, there is a risk that the compound may cause carcinogenesis and teratogenesis.

As a further technical scheme, the laundry detergent also comprises 0.1-0.2 parts of propylene glycol alginate.

As a further technical scheme, the composition comprises the following components in parts by weight: 110 parts of deionized water, 0.15 part of disodium ethylene diamine tetraacetate, 7 parts of fatty alcohol-polyoxyethylene ether, 32 parts of ethoxylated alkyl sodium sulfate, 3 parts of sulfonic acid, 10 parts of sodium hydroxide, 6 parts of citric acid, 1.5 parts of tert-butyl hydroquinone, 15 parts of sucrose fatty acid ester, 0.03 part of silver ion bacteriostatic agent, 0.2 part of kasong, 0.3 part of essence and 0.1 part of propylene glycol alginate.

As a further technical scheme, the composition comprises the following components in parts by weight: 105 parts of deionized water, 0.16 part of disodium ethylene diamine tetraacetate, 7.5 parts of fatty alcohol-polyoxyethylene ether, 32 parts of ethoxylated alkyl sodium sulfate, 4 parts of sulfonic acid, 8 parts of sodium hydroxide, 7 parts of citric acid, 1.5 parts of tert-butyl hydroquinone, 18 parts of sucrose fatty acid ester, 0.02 part of silver ion bacteriostatic agent, 0.2 part of kasong, 0.4 part of essence and 0.15 part of propylene glycol alginate.

The invention also provides a preparation method of the antibacterial laundry detergent, which comprises the following steps:

s1, adding tert-butyl hydroquinone into sucrose fatty acid ester for emulsification and homogenization to obtain an S1 mixture;

s2, stirring and mixing the disodium ethylene diamine tetraacetate and the deionized water to obtain an S2 mixture;

s3, adding fatty alcohol-polyoxyethylene ether, ethoxylated alkyl sodium sulfate and sodium hydroxide into the S2 mixture, and uniformly stirring to obtain an S3 mixture;

and S4, uniformly stirring the mixture of S1 and S3, adding other components, and uniformly stirring to obtain the product.

The bacteriostatic laundry detergent is prepared according to the preparation method.

The invention also provides application of the antibacterial laundry detergent in washing clothes.

The invention has the beneficial effects that:

1. the silver ion bacteriostatic agent is the only component which can replace chlorine to finish sterilization in the world at present, and the action mode of the bacteriostatic agent is directly converted into oxygen and water. It is a complex of hydrogen peroxide, can take effect at a concentration of substantially 100ppm ten-thousandth, and is currently a relatively stable, safe, mild ingredient. Therefore, the compound is the preferred component.

2. According to the invention, the tert-butyl hydroquinone is added, on one hand, the decontamination effect is good, on the other hand, the bacteriostatic activity of the laundry detergent can be improved, but due to the oil solubility of the tert-butyl hydroquinone, the inventor finds that the dissolving capacity and the good stability of the tert-butyl hydroquinone in a system can be improved when the fatty alcohol-polyoxyethylene ether is used for emulsification through numerous experiments, the proportion of the tert-butyl hydroquinone and the fatty alcohol-polyoxyethylene ether must be between 5% and 10%, otherwise, the stabilizing effect is poor or the bacteriostatic effect cannot be well exerted.

3. The inventor adopts propylene glycol alginate to replace the conventional thickening agent, and finds out through experimental exploration that the propylene glycol alginate can exert bacteriostatic effect to a certain extent.

Comparative example 5

The bacteriostatic laundry detergent comprises the following components in parts by weight: 105 parts of deionized water, 0.16 part of disodium ethylene diamine tetraacetate, 7.5 parts of fatty alcohol-polyoxyethylene ether, 32 parts of ethoxylated alkyl sodium sulfate, 4 parts of sulfonic acid, 8 parts of sodium hydroxide, 7 parts of citric acid, 1.5 parts of tert-butyl hydroquinone, 25 parts of sucrose fatty acid ester, 0.02 part of silver ion bacteriostatic agent, 0.2 part of kasong, 0.4 part of essence and 0.15 part of propylene glycol alginate. The preparation method is the same as that of example 1.

The laundry detergents in examples 1 to 6 and comparative examples 1 to 5 were subjected to stability and detergency tests (0.1% aqueous solution) according to "QB/T1224-.

TABLE 1 appearance, stability, soil release test results

The bacteriostatic effects of the bacteriostatic laundry liquids (0.1% aqueous solutions) of examples 1 to 6 and comparative examples 1 to 5 were tested according to the evaluation method for the antibacterial and bacteriostatic effects of QB/T2738-.

TABLE 2 results of the test of bacteriostatic effect

As can be seen from tables 1 and 2, in comparative example 1, tert-butyl hydroquinone and sucrose fatty acid ester are not added, and in comparative example 2, sucrose fatty acid ester is replaced by equal amount of fatty alcohol polyoxyethylene ether, so that the obtained laundry detergent has poor sterilization and decontamination effects.

The bacteriostatic effect of examples 1 to 3 was not as good as that of examples 4 to 6, and in comparative example 3, propylene glycol alginate was replaced with hydroxyethyl cellulose, which is a thickener, but the inventors found that propylene glycol alginate exhibited a bacteriostatic effect to some extent, and exhibited an unexpected effect.

In comparative example 4, the addition of sucrose fatty acid ester is less, so that the emulsification effect is poor, and the stability of the laundry detergent is poor, while in comparative example 5, the addition of sucrose fatty acid ester is more, so that although the stability is not affected, the excessive emulsifier causes that the tert-butyl hydroquinone cannot exert the bacteriostatic effect, and the excessive or insufficient sucrose fatty acid ester cannot achieve the optimal effect.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
