Description

Natural antibacterial detergent for lady clothes

Technical Field

The invention belongs to the technical field of daily chemicals. More particularly, relates to a natural antibacterial detergent for ladies' clothes.

Background

The conventional clothes washing products have single function and serious homogenization phenomenon at present. With the improvement of living standard, people pursue high-quality life and the demand of laundry products is diversified. The disease incidence of modern women is increased from 30% to 75%, and the body function is reduced due to poor life, hygiene habits and the like, so that the disease is difficult to resist the invasion of pathogenic bacteria. The world health organization survey reports show that: underwear, an article that is touched every day, is one of the leading causes of female illness. Because the physiological structure of women is special, if the underwear is not cleaned in place, bacteria are easy to breed in a warm and humid environment. At present, people have great demand on special washing products for women underwear.

At present, most of female washing and caring products in the market are alkaline cleaning products, but the female washing and caring products are too alkaline and contain phosphorus and fluorescent agents, so that gynecological diseases are easily induced. And the female underwear is not suitable for machine washing and hand washing, while the alkaline product has larger pH difference with the human epidermis, is more irritant to the hand skin and too dry, comprises too many additives and is not beneficial to the hand skin care.

Patent application CN201510234953.9 discloses a special laundry detergent for women's underpants, which utilizes a traditional Chinese medicine bacteriostasis formula to realize a bacteriostasis function, but does not pay attention to simultaneous efficient bacteriostasis of common infectious bacteria of three women, namely escherichia coli, candida albicans and staphylococcus aureus. Moreover, the bacteriostatic effect of traditional Chinese medicines is not very ideal, or the product has too many additives and the components are not natural.

Detailed Description

The present invention is further illustrated by the following specific examples, which are not intended to limit the invention in any way. Reagents, methods and apparatus used in the present invention are conventional in the art unless otherwise indicated.

Unless otherwise indicated, reagents and materials used in the following examples are commercially available.

Example 1 development of bacteriostatic compositions

The invention aims to explore a pure natural bacteriostatic composition which can be used for laundry products, in particular to a composition product which has strong bacteriostatic effects on three bacteria of escherichia coli, candida albicans and staphylococcus aureus.

Research on natural antibacterial component essential oil

In recent years, researches show that the essential oil components have the characteristic of inhibiting or killing certain microorganisms and can be used as a natural preservative bacteriostatic agent. In order to develop a natural bacteriostatic agent for a private underwear washing product for women, a large number of researches are carried out to preliminarily determine tea tree essential oil, thyme essential oil, lemongrass essential oil (lemongrass essential oil), basil essential oil, sweet orange essential oil, grapefruit essential oil and the like as main bacteriostatic essential oils, and further carry out bacteriostatic detection experiments (as shown in table 1).

TABLE 1

Test results show that most of the essential oils have strong inhibition effects on escherichia coli and staphylococcus aureus, but have little effect on candida albicans. Therefore, the pure essential oil bacteriostasis system cannot simultaneously achieve the bacteriostasis rate of at least 50 percent on escherichia coli, candida albicans and staphylococcus aureus.

Secondly, screening essential oil compound components

Based on the result that the essential oil cannot meet the requirement of the essential oil on the bacteriostasis rate, compounding of various bacteriostasis components such as salicylic acid, propylene glycol, CAS-100N and the like with the essential oil is continuously tried, but the effects are still not ideal. Therefore, new antibacterial components which have good antibacterial effect and can be compounded with the essential oil are continuously searched until lauroyl arginine ethyl hydrochloride (LAE) is found, the antibacterial rate of escherichia coli, candida albicans and staphylococcus aureus can be guaranteed to be not less than 50%, and the antibacterial effect can be remarkably improved by compounding with the essential oil. The specific data are shown in Table 2.

TABLE 2

To sum up, the composition for remarkably improving the bacteriostatic effects of the three bacteria is determined as follows: tea tree essential oil, lemongrass essential oil and lauroyl arginine ethyl ester hydrochloride.

In addition, the mass ratio of each substance is optimized through a single-factor experiment and an orthogonal experiment, and the mass ratio of the three antibacterial components can be controlled to be 0.02-0.2: 0.02-0.2: 0.1-0.5; the optimal mass ratio is 0.09: 0.05: 0.2 (as in table 3).

TABLE 3

Example 2 research and development of bacteriostatic composition special for laundry detergent

1. Optimization of LAE bacteriostatic system

Lauroyl arginine acetate hydrochloride (LAE) is a cationic surfactant with the molecular formula: the C20H41N4O3Cl is a white hygroscopic solid, has stable chemical property within the range of pH3-7, has higher bacteriostatic activity, has a melting point of 50-58 ℃, has a distribution coefficient of more than 10 in water and oil, namely is mainly present in a water phase, and compared with other preservatives with different chemical structures and similar functions, the LAE can be more conveniently dissolved in a water-based food and cosmetic system to better exert the bacteriostatic effect. Lauroyl arginine ethyl ester hydrochloride (LAE) has excellent safety, is hydrolyzed into compounds which are taken in daily diet of human body through chemical and metabolic routes in human body, and is mostly used as preservative in meat food and poultry food in the prior art. The antibacterial liquid laundry detergent is rarely used in the field of daily chemicals, particularly in laundry detergents, and is not reported to be used as an antibacterial component in the laundry detergent products.

We found that the bacteriostatic effect of LAE is significantly inhibited by the laundry detergent system. In our research, 0.3% of LAE is directly added into a formula of a laundry detergent containing an essential oil bacteriostatic system, so that the bacteriostatic effect on escherichia coli, candida albicans and staphylococcus aureus is worse than that of the original essential oil bacteriostatic formula, and the bacteriostatic rates on the escherichia coli, candida albicans and staphylococcus aureus are respectively reduced from 92.24%, 90.21% and 97.14% to 11.29%, 6.67% and 72.34%.

Through multi-party research, the surfactant component is mainly found to influence the LAE antibacterial effect, so that the optimization experiment research is carried out on the proper surfactant.

Preparing a laundry detergent by using LAE as a bacteriostatic component, wherein the basic system is as follows 4:

TABLE 4

Each experimental group is different in surfactant system, each prepared group of laundry detergents is diluted according to a ratio of 1:8 and then is subjected to an antibacterial experiment, and the antibacterial rate after 20min is tested (part of data is shown in table 5):

TABLE 5

By adjusting the type of the surfactant, the addition amount of the LAE is also 0.3%, and under the condition of not adding essential oil, the three bacteria all reach the bacteriostasis rate (system 1) of more than 50%, thereby meeting the requirement of people on the bacteriostasis rate. Therefore, a surfactant system consisting of cocamidopropyl betaine, lauryl glucoside and disodium cocoyl glutamate is selected to be compounded with the LAE to prepare the antibacterial laundry detergent. In the surfactant combination, the cocoamidopropyl betaine is a zwitterionic surfactant, the lauryl glucoside is a nonionic surfactant, the cocoyl disodium glutamate is a weak anionic surfactant, and the cocoamidopropyl betaine, the lauryl glucoside and the cocoyl disodium glutamate are compounded and comprehensively coordinated, so that the detergency and the foamability of the laundry detergent can be ensured, and the inhibition effect of a conventional laundry detergent system on the LAE (laundry detergent emulsion) antibacterial effect is reduced to the minimum.

2. In summary, we have determined that the bacteriostatic composition useful for bacteriostatic laundry detergents (especially for lady's underwear) is: tea tree essential oil, lemongrass essential oil, lauroyl arginine ethyl ester hydrochloride, cocamidopropyl betaine, lauryl glucoside, and disodium cocoyl glutamate.

In addition, the mass ratio of the substances is optimized through a single-factor experiment and an orthogonal experiment, and the mass ratio of the tea tree essential oil, the lemongrass essential oil, the lauroyl arginine ethyl ester hydrochloride, the cocamidopropyl betaine, the lauryl glucoside and the sodium cocoyl glutamate can be controlled to be 0.02-0.2: 0.02-0.2: 0.1-0.5: 5-10: 8-15: 5-10; the optimal mass ratio is 0.09: 0.05: 0.2: 8: 12: 8.

Second, detection of physicochemical Properties and detergency

1. Entrusted testing organization: the analysis and detection center of the national institute of daily chemical industry. The detection result is 14.

TABLE 14

The result shows that the detergent has the detergency JB-02 more than 2.8 and is 2.8 times of the standard requirement (the requirement of the industry standard for JB-02 is more than or equal to 1). Meanwhile, the formula is a weakly acidic formula, has the pH value of 5.6, conforms to the pH value of human epidermis, has little stimulation to the hand skin, and cannot feel dry.

Third, desmearing test

(1) Experimental materials: dropping fresh duck blood on Modal cotton cloth, and naturally drying for 24 hr.

The laundry detergent to be tested: the invention relates to a detergent, a pharmaceutical female underwear lotion of Japan, a special washing liquid for French Shu organic underwear and a special washing liquid for bright hand washing of certain month.

The cleaning method comprises the following steps: and after cotton cloth is fully soaked, respectively taking the same amount of laundry detergent to coat the laundry detergent on bloodstains, scrubbing for 60s, cleaning, and taking a picture for comparison.

The results are shown in FIGS. 1 and 2. The detergent disclosed by the invention has a very strong blood stain removing effect and is obviously superior to the products on the market.

(2) Experimental materials: antarctic people pure cotton pants. Dripping three drops of fresh duck blood on each piece of cloth, standing, air drying for 48h, and cleaning. The test was intended to test and compare the removal of very difficult-to-remove old stains (48h) with several laundry detergents.

The laundry detergent to be tested: the detergent of the invention (Qianjin moisture natural authentication type), pharmaceutical female underwear lotion of Japan, special washing liquid for French Shi Yishu organic underwear, anti-bacterial detergent for inflammation, Xiamen product formula 1 and Xiamen product formula 2.

The cleaning method comprises the following steps: preparing six plastic basins, respectively adding the same amount of clear water, soaking each piece of bloodstain cloth in water for 60s, taking 2ml of laundry detergent at the bloodstain, scrubbing for 60s, rinsing to remove foams, and taking a picture for comparison.

The results are shown in FIGS. 3 and 4. The test result of instant cleaning shows that the blood stain removing effect of the natural authentication type underwear detergent is the best, and the blood stain removing effect is the best in Yanjie, Leshu in France, pharmacy in forest, mansion door 1 and mansion door 2.

Although the bloodstain is not completely removed, the influence on the practical application of the product is small, and the reasons are three: (1) the female can clean the bloodstain of the underpants in time, which is not more than 24 hours; (2) a layer of thin and soft pure cotton fabric is added at the crotch part of common pure cotton underwear, so that the blood stain cleaning difficulty is greatly reduced; (3) few women will wear pure white underwear or will choose other softer, more skin-friendly fabrics like modal. Therefore, the antibacterial underwear detergent (natural authentication type) can completely meet the requirement of removing bloodstains from women's underpants, and has stronger cleaning power than similar competitive products.
