Abstract

In our work we dealt with microbial contamination of cosmetics products. Microorganisms have important role in our lives. They are used in food processing and in pharmacy, but their pathogenic triebes can mean health risk for costumers. Hundred thousands of people use cremes every day. That‘s why we think, that this topic is important and results can be relevant for practice. In cosmetics products is sterility not expected, but some of specific microorganisms are controlled. These microorganisms can mean health risk for users. As model microorganism we chose yeast Candida glabrata. Genus Candida can cause oral and genital infections. We could not work with pathogenic triebes so we chose nonpathogenic. We also chose bakteria Escherichia coli, which is an indicator of fecal contamination. If E. coli is in product, it means, that there are lacks of hygiene. Conservants should have same effect against contamination caused by all species of bacterias and yeasts [1,2]. Our aim was verificaion of effectiveness of conservants K 145 and K 702 against contamination caused by mentioned microorganisms. Principle of effect of conservants are chemical reactions with microorganisms. Conservant K 145 has these active substances: 2-Bromo-2-Nitropropane-1.3-Diol, Methylchloroisothiazolinone, Methylisothiazolinone. Conservant K 702 has these active substances: Phenoxyethanol, Benzoic Acid, Dehydroacetic Acid, Ethylhexylglycerin, Polyaminopropyl Biguanide. Every conservant used in the European union has its own maximum authorised concentration. For conservant K 145 this vaule is 0.2%, for conservant K 702 it is 1%. Conservant K 145 is not recommended for products used for mucous membranes and lips and also for toothpastes. Conservant K 702 can be used for leave-on as well as rinse-off products [3,4].

验证保育剂k145及k702的有效性
在我们的工作中,我们处理化妆品的微生物污染。微生物在我们的生活中扮演着重要的角色。它们被用于食品加工和制药,但它们的致病部落可能意味着对消费者的健康风险。每天有成千上万的人使用面霜。这就是为什么我们认为,这个话题很重要,结果可以与实践相关。在化妆品产品中是无菌性不被期望的,但是一些特定的微生物是被控制的。这些微生物可能对使用者构成健康风险。我们选择了酵母平滑念珠菌作为模式微生物。念珠菌属可引起口腔和生殖器感染。我们无法研究致病的部落所以我们选择了非致病的部落。我们还选择了大肠杆菌,这是粪便污染的一个指标。如果产品中有大肠杆菌,那就意味着缺乏卫生。对于所有种类的细菌和酵母菌造成的污染,保原剂应具有相同的效果[1,2]。我们的目的是验证保护剂k145和k702对上述微生物污染的有效性。保护剂的作用原理是与微生物的化学反应。保守的k145有这些活性物质:2-溴-2-硝基丙烷-1.3-二醇,甲基氯异噻唑啉酮,甲基异噻唑啉酮。保守的k702有这些活性物质:苯氧乙醇、苯甲酸、脱氢乙酸、乙基己基甘油、聚氨丙基双胍。在欧盟使用的每一种防腐剂都有自己的最高许可浓度。对于保守的k145,这个值是0.2%,对于保守的k702,这个值是1%。保守的k145不建议用于粘膜和嘴唇的产品,也不建议用于牙膏。保洁剂k702可用于免洗产品,也可用于冲洗产品[3,4]。
