Control indicators and testing standards for microorganisms in cosmetics

Biotechnology Channel News: Microbial contamination of cosmetics not only affects the quality of the product itself, but also endangers the health and safety of consumersTherefore, countries all over the world attach great importance to the health standards of microorganisms in cosmetics, the pollution of microorganisms in cosmetics as a quality index of products, to prevent and control the pollution of cosmetics, which improve the quality of cosmetics and ensure the safety of cosmetics has an important significance(1) The control index of microorganisms in cosmetics on the control index of microorganisms in cosmetics, there is no uniform standard in the world, countries are based on their own situation to develop their own cosmetics micro-organisms indicatorsTwo points need to be explained:(1) in various countries on the microbiological control indicators in cosmetics is the first is the total number of bacteria indicators, such as China's regulations in the eyes, lips, oral mucous film cosmetics and infant and children's cosmetics bacteria must not be greater than 500 / ml or 500 / 8, the total number of other cosmetics bacteria must not be greater than 1000 / mi or 1000it refers to the number of bacteria in unit capacity (m1) (or unit weight (g), which is referred to here as a unit of bacterial countingIn the actual detection of the total number of bacteria in cosmetics, the total number of live bacteria is cultivated under certain conditions after the test sample treatment, the number of colony-forming units (in cfu)colony (colony) it is a unique form of microbial bacteria, refers to the development of bacteria on solid media and the formation of growth that can be recognized by the naked eye, it is made up of tens of thousands of the same bacteria, so there is a bacterial colonyTherefore, the total number of colonies refers to the total number of bacteria contained in each g or per m1 cosmetics on solid media, under certain conditions after culture produced by the total number of bacteriaBacterial cells based on cosmetic samples are present in a single, double, stinar, grape-like or piles, so the colonies that appear on the medium plate can be derived from cell blocks or from individual cells, so the number of oxygen needs and conjugant anaerobic colonies should not be expressed in the total number of bacteria (or the number of live bacteria), but should be formed in units of mass (g) or capacity (m1) in the form of bacteria(m1)And generally still in (m1), only in the actual test, the detection is actually cfu/g (m1)(2) The second indicator of microbes in cosmetics in various countries is that cosmetics must not contain pathogenic bacteriaThe definition of pathogenic bacteria should be very clear in microbiology, but its connotations include bacteria that are very wideIn the microorganism indicator in cosmetics, the pathogenic bacteria referred to should be specific identified bacteriaSpecia microor-ganism is a specific microorganism that cannot be detected in cosmetics, including pathogenic and conditional pathogenic bacteriaThere are no uniform provisions in the world for the determination of specific bacteria, and each country is differentThere are 10 specific bacteria, such as E coli, Krebs, salmonella, Morphite, Les Porma, Staphylococcus aureus, maltoma pseudomonas, polyseofmy, no nitrosis, sticky salinitus; 3 species: Cynobacteria, Staphylococcus aureus, E coli (Japan for E coli group); China and Japan prescribe the same specific bacteria (2) The standard of detection of microorganisms in cosmetics In China promulgated the standard of cosmetichygienc, is China's cosmetics health regulations, the national cosmetics production and sales enterprises and other departments must be implemented, health supervision departments should be strictly supervised In order to implement and supervise the implementation of standards, the microbiological testing of cosmetics is essential, in order to standardize the microbiological testing of cosmetics, China has promulgated a series of standard methods for microbiological testing, including: the general rules, the total number of bacteria, fecal coliforms, pneumonobacteria, Staphylococcus aureus and other 5 standards (GB 7918 1—5 87)。 The implementation of these standards, so that China's cosmetics microbial pollution has significantly improved, but the microbial pollution of cosmetics is still an important factor affecting the quality and safety of Cosmeticproduct products in China According to a coastal area health department in the region 623 kinds of cosmetics microbiological testing, the result is that the total number of bacteria exceeded the standard of 73 species, the rate of exceeding the standard of 11 72% and 14 species of fecal coliform were detected, with a detection rate of 2 25%; 14 species of lactus bacteria were detected, with a detection rate of 2 25%。 It can be seen that the microbial pollution of cosmetics in China is not optimistic, but also must greatly improve the health of cosmetics, improve the health and safety level of cosmetics What are microorganisms? Microbes are tiny organisms that are invisible or invisible to the naked eye They are small in size and simple in structure It is closely related to mankind, it can benefit both human beings and bring devastating disasters to mankind microbiology plays an important role in solving major social problems in the modern era Microbial oil extraction, for example, plays an incredibly large role It can reduce the viscosity of crude oil, increase the liquidity of crude oil, thereby greatly improving the recovery rate of crude oil This kind of technology is low in cost, simple equipment, does not harm the formation, does not pollute the environment, and the benefits are significant From 1995 to 2000, snooker Petroleum Technologies implemented the technology and achieved good results Japan, on the other hand, composed of more than 80 kinds of microorganisms with different functions, such as photosynthesis, lactic acid bacteria, yeast, fermented silk bacteria, line bacteria and other functions These microbial combinations, in a single body, promote each other to form a complex and stable multi-functional micro-ecosystem that inhibits the activities of harmful microorganisms, especially pathogens and corrupt bacteria, and promotes plant growth This technology is widely used in natural agricultural law With the development of national economy, the application of microorganisms is becoming more and more extensive Microbes play an important role in biopharmaceuticals, energy, environmental protection, food, industry, etc however, microbes have brought many benefits to humanbeings, but also brought many negative effects that can not be ignored The cosmetics we use contain a variety of nutrients, providing a suitable environment for the growth of microorganisms, in the production, storage and use of the process is highly susceptible to microbial contamination Common bacteria in cosmetics mainly to bacillus, pseudomonas, staphylococcus-based, these genus bacteria in the natural world widely distributed, strong resistance to the environment, pollution opportunities more Fungi mainly have wood mold genus, couric genus, root mold genus, vasculature genus, short stem mold genus, false silk yeast genus and red yeast genus, these bacteria are also common mold and yeast in the natural environment Cosmetics contaminated with microorganisms not only have products corrupt and spoiled, but more importantly, pathogenic microbial contamination will cause harm to human health Other drinking fountain pollution has also become a health problem that can not be ignored, some drinking water quality has been far from qualified drinking water hygiene quality, so-called pure water, mineral water, etc can not be directly drinking, mainly by E coli and other microorganisms pollution This condition is likely to exacerbate the prevalence of intestinal disease in summer and autumn The researchers also point out that there is also microbial contamination in indoor air, which can cause eye irritation, asthma, allergic dermatitis, allergic pneumonia and infectious diseases, and even death from infection Indoor building materials and household appliances are the main sources of indoor air, which can not only release harmful chemicals to human body, but also provide favorable conditions for the growth of microorganisms it is clear that microbes are very close lying with humans, not only for the benefit of human beings, but also for human harm Therefore, we should recognize the microorganism correctly and use it to protect the environment and benefit humanity, which is our expectation and the duty of each of us
