Description

A kind of green and safe laundry detergent for removing sweat and odor and preparation method thereof

Technical field

The invention relates to the field of polyurethane elastomers, and in particular to a green and safe deodorizing laundry detergent and a preparation method thereof.

Background technique

Laundry detergent is one of the most frequently used detergents in daily life and is an indispensable part of daily life. After years of development, the functions of laundry detergent have also undergone great changes, from the initial cleaning function to the combination of washing and care. As people's living standards continue to improve, in particular, people pay more attention to a healthy lifestyle and have higher requirements for laundry detergents. People's demand for washing supplies is constantly escalating. In addition to good detergency, it is also required to have other additional functions such as softness, easy bleaching, color protection or sterilization. This has also promoted the development of laundry detergents in a diversified and personalized direction.

Odorhidrosis refers to sweat with odor, and there are two types of odoriferous hyperhidrosis: systemic odoriferous hyperhidrosis and localized odoriferous hyperhidrosis. In the latter, armpit odor and foot odor are the most common. A large amount of stinky sweat on human skin is often caused by abnormal sweat secretion by the apocrine glands. The sweat secreted by the normal eccrine glands is often odorless. However, in the case of excessive sweating, the sweat is decomposed by bacteria attached to the surface and releases fatty acids to form Stink. Systemic dyshidrosis is often a physiological change, usually related to nerves, and only a few are pathological. Patients with dyshidrosis are often accompanied by excessive sweating, and about 80.0% of patients with dyshidrosis worldwide. Patients with dyshidrosis will emit unpleasant odors from their bodies in daily life, and people around them may look at them strangely after smelling it. Excessive sweat will stain clothes yellow, causing trouble in cleaning. Excessive sweat can easily breed bacteria. Various bacteria cause skin diseases; too much water is lost in the body, feces is accumulated in the body, and the body repeatedly absorbs toxins in the body, causing dull skin color, etc.; the odor produced may cause patients to become autistic and feel lonely and embarrassed. Some Patients may even suffer from severe depression.

Health has always been a topic of greatest concern to consumers, and it is also a new source of wealth growth for companies. Therefore, major detergent manufacturers hope to use detergents to enable people to remove sweat and odor through daily cleaning activities, thereby creating a healthier and greener lifestyle for consumers.

Contents of the invention

In view of the problems existing in the prior art, the purpose of the present invention is to provide a green and safe deodorizing laundry detergent and a preparation method thereof.

The purpose of the present invention is achieved by adopting the following technical solutions:

In a first aspect, the present invention provides a green and safe antiperspirant and odor-removing detergent, which, calculated according to mass fraction, includes:

Surfactant 5-10%, bacteriostatic agent 0.5-2%, regulator 0-2.0%, biological surfactant 2-10%, enzyme 0-1.5%, thickener 0-5%, flavor 0-1% , sweat odor eliminator 0-2%, preservative 0-0.5%, the balance is deionized water.

Further, the surfactants include anionic surfactants and nonionic surfactants.

Furthermore, the anionic surfactant is selected from at least one selected from the group consisting of sodium fatty alcohol polyoxyethylene ether sulfate, sodium fatty acid methyl ester sulfonate, and sodium lauryl sulfate.

Furthermore, the nonionic surfactant is selected from at least one of fatty alcohol polyoxyethylene ethers, isomeric alcohol polyoxyethylene ethers, and castor oil polyoxyethylene ethers.

The inventor found that the use of anionic surfactants in combination with nonionic surfactants can improve the decontamination ability. In particular, the combination of fatty alcohol polyoxyethylene ether sodium sulfate and fatty alcohol polyoxyethylene ether greatly improves the decontamination ability.

Further, the regulator is selected from at least one of potassium sodium tartrate, citric acid, sodium citrate, disodium ethylenediaminetetraacetate, and nitrilotriacetic acid.

Further, the bacteriostatic agent is one or more of triclocarban (TCC), triclosan (TCS), diclosan (HP-100), and p-chloroxylenol (PCMX).

Furthermore, the bacteriostatic agent is preferably diclosan (HP-100).

Diclosan (HP-100), whose chemical name is 4,4-dichloro-2-hydroxydiphenyl ether, or HP-100 for short, is normally a light yellow liquid. A solution that is insoluble in water but soluble in organic solvents and surfactants. It can be compounded with anionic, nonionic, amphoteric and cationic surfactants. It has a heat resistance of up to 200°C and has good performance in alkaline environments. stability. HP-100 is a safe and efficient broad-spectrum antibacterial agent, which has good inhibitory effect on both Gram-positive bacteria and Gram-negative bacteria. Suitable for use in household and fabric care products, kitchen appliances or hard surface cleaning. Many antibacterial products on the market now add TCC or TCS ingredients. Some studies cited by the FDA show that long-term exposure to certain active ingredients in antibacterial products, such as triclosan and triclocarban, can affect the body's resistance or hormone levels, posing health risks. This news has caused consumers to have a psychological shadow on the safety of triclosan and triclocarban, and their recognition of this type of products has declined. Since diclosan has one less chlorine atom than triclosan and is less irritating to the human body, it has a tendency to replace triclosan.

Further, the sweat odor eliminator is a composite active deodorant with a particle size of 4-10 μm.

Furthermore, the components of the composite active deodorant are chitosan as the skeleton and zinc/ricinoleic acid catechin ester as the active substance.

Furthermore, the preparation process of the composite active deodorant is:

S1. Weigh the chitosan and acetic acid solution and mix them in a beaker, stir until all are dissolved to form a chitosan solution;

Among them, the concentration of acetic acid solution is 1%, and the concentration of chitosan after dissolution is 5-10mg/mL;

S2. Weigh ricinoleic acid and catechin and mix them into the reaction vessel, add nitrogen as protective gas, add p-toluenesulfonic acid, gradually raise the temperature to 180-200°C, keep the reaction for 3-5 hours, then cool to room temperature. After separation and purification, ricinoleate catechin ester is obtained;

Among them, the molar ratio of ricinoleic acid to catechin is 2-4:1, and the amount of p-toluenesulfonic acid added is 1%-5% of the mass of ricinoleic acid;

S3. Weigh the zinc pyrophosphate and sodium hydroxide solution, mix them, and stir until dissolved to form a zinc pyrophosphate solution;

Among them, the concentration of sodium hydroxide solution is 0.1g/mL, and the concentration of zinc pyrophosphate dissolved in sodium hydroxide solution is 3-5 mg/mL;

S4. Stir and mix the ricinoleic acid catechin ester and the chitosan solution in the flask, add the zinc pyrophosphate solution drop by drop, and continuously stir the liquid in the flask with a stirrer. The dripping acceleration rate is 20- 30 drops/min, after all the drops are added, continue stirring for 0.5 hours, centrifuge to separate out the lower precipitate, and after drying and pulverizing under reduced pressure, a composite active deodorant is obtained;

Among them, the mass ratio of ricinoleate catechin ester, chitosan solution and zinc pyrophosphate solution is 2.4-4.8:20-40:10-20.

Further, the preservative is selected from one or more of Casson, potassium sorbate, sodium benzoate, etc.

Further, the enzyme is: at least one of protease (ROC250 LC) British enzyme preparation, cellulose purifying enzyme (FLX1) British enzyme preparation, mannanase (M9) British enzyme preparation.

Further, the biosurfactant is at least one of SLONE (biosurfactant, ECCECRT certified) and SD100 (biosurfactant, ECCECRT certified).

Further, the thickener is at least one of propylene glycol, glycerin, and coconut oil betaine.

In a second aspect, the present invention provides a method for preparing a green and safe deodorizing detergent, which includes:

(1) Pour deionized water into the container, then add surfactant and biological surfactant to dissolve. After stirring evenly, add sweat odor eliminator and continue stirring until uniform to obtain mixed liquid A;

(2) Pre-dissolve the bacteriostatic agent with a thickener, then add it to Mixed Liquid A, stir evenly, and prepare Mixed Liquid B;

(3) Add preservatives, enzymes and flavors to the mixed solution B in sequence, stir evenly and add a regulator to adjust the pH to obtain a green and safe deodorizing laundry detergent.

The beneficial effects of the present invention are:

Principle of the invention: Through the mechanism of sweat odor produced by the human body, bacteriostatic agents and sweat odor eliminators are added to the detergent in a targeted manner. Through the antibacterial effect of the detergent, bacteria attached to the surface of sweat are eliminated and the generation of odor is reduced. , the sweat odor eliminator is adsorbed into the fabric through technology, and is released along with the movement of the human body to eliminate sweat odor.

The surfactant extracted by biological fermentation used in the present invention has a high degree of biodegradation, making the product more environmentally friendly and safer.

The composite active deodorant of the present invention uses ricinoleate catechin ester synthesized from ricinoleic acid and catechin as the active material, chitosan as the wrapping material, and zinc pyrophosphate solution as the cross-linking agent. Thus, a compound material with excellent antibacterial and deodorizing effects was prepared. Among them, chitosan is not only used as a wrapping material, but also has an antibacterial effect; zinc pyrophosphate solution is not only used as a cross-linking agent, but also contains metal zinc ions that can coordinate and chelate with ricinoleic acid catechin ester, And has a strong deodorizing effect.

The existing active ingredient zinc ricinoleate is known to bind and remove harmful and odorous substances such as sulfur compounds (thiols, thioethers, thiols), nitrogen compounds (amines) and carboxylic acids (butyric acid, isopentyl acid, etc.). However, pure zinc ricinoleate itself is insoluble in water and has almost no activity. It needs to be activated before it can show the deodorizing effect. It is usually combined with a chelating agent in water for activation treatment, which results in its ability to be used during the washing process. It has a deodorizing effect, but the deodorizing effect on washed clothes is less durable. The active substance zinc/ricinoleate catechin ester of the present invention is a product that has been directly activated. Even without additional chelating agents, it can be quickly dispersed in water, and the chitosan-based coating can It remains on the surface of clothing and continuously generates active molecules to combine with odor molecules, thereby achieving a long-term deodorizing effect.

The ingredients of the detergents prepared in Examples 1-3 and Comparative Examples 1-2 are summarized in Table 1:

Table 1 Comparison of the ingredients of different detergents

Performance tests were performed on the laundry detergents obtained in the above-mentioned Examples 1-3 and Comparative Examples 1-2.

Experimental testing

The test items and conditions are as follows:

1. Decontamination performance test: Measured with reference to GB/T13174-2008, including the decontamination value of carbon black stain cloth (JB-01), protein stain cloth (JB-02), and sebum stain cloth (JB-03) Decontamination value, the larger the value, the better the decontamination performance.

The test results are shown in Table 2:

Table 2 Comparison of decontamination capabilities

Carbon black stain removal value Decontamination value of protein stain cloth Decontamination value of sebum stain cloth Implementation case 1 15.3 11.2 10.8 Implementation case 2 15.0 11.2 10.6 Implementation case 3 15.1 11.0 11.0 Comparison case 1 14.8 11.1 10.3 Comparative case 2 15.0 10.8 10.5

2. Antibacterial performance test: The antibacterial rate of Gram-negative bacteria, Staphylococcus aureus and Escherichia coli was tested on clothes washed with the same method. The higher the antibacterial rate, the better the antibacterial performance. The test results are shown in Table 3:

Table 3 Antibacterial performance testing

Gram-negative bacteria Staphylococcus aureus E. coli Implementation case 1 98.52 99.98 99.80 Implementation case 2 99.21 99.92 99.90 Implementation case 3 99.87 99.97 99.90 Comparison case 1 55.70 68.11 60.35 Comparative case 2 87.2 92.31 89.25

As can be seen from Table 3, the antiperspirant and odor-removing laundry detergents of Examples 1-3 of the present invention have better antibacterial properties. From the data of Comparative Example 1 and Comparative Example 2, it can be seen that the antibacterial rates of Gram-negative bacteria, Staphylococcus aureus and Escherichia coli are different, indicating that the selection of bacteriostatic agents plays a key role in antibacterial performance. Although Comparative Examples 1 and 2 also added a certain bacteriostatic agent, the retention may be poor. According to the data of Comparative Example 2, it can be judged that the subsequent antibacterial effect on clothes is more likely to be a sweat odor eliminator.

3. Sweat and odor removal test:

In order to verify the antiperspirant and deodorizing effect of the antiperspirant and deodorant laundry detergent samples, the deodorant and deodorant laundry detergent samples of the above three embodiments were used, distributed to several experiencers for trial use, and usage data were collected.

experiment method

Experiencers wear clothes washed with anti-perspirant and odor-removing laundry detergent to work, and record their experience according to the table below when they get off work.
