Description

Underwear laundry detergent containing yeast fermentation product extract

Technical Field

The invention belongs to the technical field of washing products, and particularly relates to an underwear laundry detergent containing a yeast fermentation product extract.

Background

Everyone is likely to suffer from skin disorders because most skin disorders occur through the transmission of microorganisms on clothing. This has led to an increasing desire by consumers to use highly effective antimicrobial laundry products that can be sterilized and blocked from microbial transmission during the daily laundering of laundry, reducing the likelihood of daily illness. Therefore, the demand of consumers also promotes the diversified development of washing products, and the antibacterial laundry detergent is widely applied to the life of people.

However, most of the conventional antibacterial laundry detergents achieve the purpose of removing bacteria by adding chemical bacteriostatic agents, such as Parachlorometaxylenol (PCMX), triclosan and the like, which are commonly used bacteriostatic and bactericidal components, these bacteriostatic and bactericidal active substances only have the function of partially inactivating harmful microorganisms on clothes, and cannot remove microbial films (bacterial films) attached to the clothes, and the chemical bacteriostatic agents usually contain chlorine and have certain irritation, and improper use of the chemical bacteriostatic agents may cause skin irritation or damage to the skin. Microbial films are protective umbrellas and nutrient donors of microorganisms that are difficult to remove and easily regenerate once formed on clothing. The main reason is that bacteria have strong adhesion, once the bacteria adhere to the surface of clothes, extracellular polysaccharide is secreted, then the bacteria begin to rapidly breed, polysaccharide is continuously secreted on the surface of the fabric, gaps among bacteria are filled, a layer of bacterial plaque or biological film stain is formed in a short time, and the bacterial plaque or biological film stain is difficult to remove after a long time.

The yeast fermentation product extract contains glycolipid type biosurfactant, and according to the principle of 'similar intermiscibility', the biosurfactant can effectively decompose and remove microbial membranes (mycoderm) through a special amphoteric molecular group structure, can effectively remove skin pathogenic bacteria, and has unique and innovative action mechanism which is obviously different from that of the traditional surfactants and bactericides. The yeast fermentation product extract is applied to the laundry detergent, so that microorganisms and microbial films on clothes can be effectively decomposed and removed, stubborn stains (such as stubborn blood stains on underwear) on the clothes can be thoroughly removed, the natural fermentation product cannot damage the clothes and irritate the skin, the natural fermentation product has biodegradability, natural pollution cannot be caused, the green environmental protection concept is met, and the yeast fermentation product extract is suitable for cleaning and sterilizing high-grade underwear and cleaning infant clothes.

Example 6

A commercial product containing bacteriostatic agents was used as a control.

The main efficacy of the related laundry detergent is verified as follows:

1. decontamination capability: measured according to the specification of QB/T1224-; the detergency of the respective examples was calculated and compared, and the results are shown in table 1: table 1: detergency of each example

Table 1: detergency test

2. The effect of removing blood stain of stubborn underwear in the market is as follows:

the stubborn underwear bloodstains are difficult to be removed by using common laundry detergent and always leave traces, because the stubborn underwear bloodstains are more than a complete biological membrane, the stubborn underwear bloodstains are difficult to be completely dissolved and removed by using common surfactant or clothing detergent. In this test, the samples of examples 1 to 6, 6 in total, were distributed to A to F6 volunteers for use (the removal of tough blood stain in underwear was tested by soaking for 20 to 60 minutes, and observation was made to test the concentration of 300ml of water plus 5ml of sample, which was then rubbed once by hand, and the results of the return visit are shown in Table 2:

table 2: removing blood stain from underwear

3. Biofilm (pellicle) removal capacity simulation experiment: (1) preparing 10 cotton sheets (silk fabrics) with the same specification; (2) after autoclaving, each piece of fabric was put into a bacterial suspension of equal amounts of microorganisms (bacteria and fungi) and cultured for 48 hours (formation of a bacterial film); (3) the cotton pieces (silk fabrics) after culture were taken out and divided into five groups, soaked for 30 minutes (temperature 25 ℃) by using the laundry detergents (concentration 10%) of examples 1, 2, 3, 4 and 5 respectively, and then washed once by deionized water, and the soaking and washing methods and the concentrations of the samples were kept the same and the sterile state is kept in the process. Finally, five groups of treated samples were suspended and dried (sterile environment), and the residual condition of the microbial film on each group of silk fabrics was observed by using a microscope, and the results are shown in table 3:

table 3: simulation experiment result of biological membrane (mycoderm) removal effect

4. Irritation property: preparing the to-be-detected embodiment into a solution with the mass fraction of 10%, adding a certain amount of zein, stirring for 2 hours at 25 ℃, and then filtering. The zein values for the examples were calculated and are shown in Table 4

Table 4: zein values of the examples

The efficacy test conclusion of the involved laundry detergent is as follows:

according to the results in table 1, the laundry detergents of the present invention are the laundry detergents of example 1, example 4 and example 5, and the detergency of the three examples is obviously compared with that of the standard laundry detergent, which proves that the detergent is superior to the detergent of the product without yeast fermentation product extract in the formula, including the commercial products

Remove underwear bloodstain market according to table 2 and adjust consumption feedback results: the underwear cleaning agent has good underwear stubborn blood stain removing effect in the embodiments 1, 4 and 5, and particularly, the underwear cleaning agent has the best effect in the embodiment 5.

The results of the biofilm (pellicle) removal effect simulation experiment were as follows: the experimental results show that examples 1, 4 and 5 of the present invention have better biofilm (pellicle) removal effects than examples 2 and 3. In terms of the performance of removing the biofilm (see fig. 1 and fig. 2), the surfaces of the silk fabrics of the examples 1, 4 and 5 are relatively smooth, the biofilm (bacteria film) is basically washed off, and the attached biofilm is obviously removed. Meanwhile, the underwear laundry detergent containing the yeast fermentation product extract provided by the invention is proved to be capable of more effectively removing the biological fungus membranes on the surface of clothes (see the attached drawing of the specification) compared with the underwear laundry detergent containing the traditional bacteriostatic agent in example 2

Comparative irritation results according to table 4 for the examples: the experimental results of the zein values show that the zein values of the laundry detergents of the invention in the example 1, the example 4 and the example 5 are obviously lower than those of the laundry detergent of the example 2 without the yeast fermentation product extract, which indicates that the laundry detergents are low in irritation and milder and have no irritation.

Finally, it can be seen from the comparison of examples 4 and 5 with example 1 that the main efficacy of the yeast fermentation product extract of the present invention is not affected when other components in the laundry detergent are changed.
