摘要

对目前可获得的17种伊朗制造的洗发水产品的防腐剂容量进行了测量。购买时,细菌计数显示没有任何微生物污染的痕迹。洗发水瓶子被分发给17名女研究生,她们当时住在塔比亚特莫德雷斯大学(TMU)的不同宿舍。40天后,将分配的瓶子归还,并在相同的条件下重复其细菌计数。令我们惊讶的是,没有观察到任何微生物污染的痕迹。考虑了三种可能性。这家工厂有效地使用了防腐剂。2)洗发水成分本身具有杀菌作用。3) TMU有卫生条件,没有任何微生物污染物!显然,第三种可能性被排除了。第二种选择也被抛弃了,因为洗发水的四种主要成分,包括十二烷基醚硫酸钠(SLES)、甜菜碱、椰子脂肪酸和甘油,实际上没有任何显著的抗菌活性。因此,最有可能的是第一种,因为故意污染了17个品牌;工厂使用的防腐剂[5-氯-2-甲基-4-异噻唑啉-3- 1和2-甲基-4-异噻唑啉-3- 1 (KATHON CG)]证明对四种主要污染物具有很强的杀菌作用:大肠杆菌、金黄色葡萄球菌、铜绿假单胞菌和耐甲氧西林金黄色葡萄球菌(MRSA)。

Analysis of Preservative Capacity for Contemporary Iranian Shampoos
Preservative capacity is measured for seventeen currently accessible Iranian made shampoo products. Upon purchase, bacterial counts show no trace of any microbial contamination. The shampoo bottles are distributed to seventeen female graduate students, residing at the time in different dormitories of Tarbiat Modares University (TMU). After 40 days, the allocated bottles are returned and their bacterial counts repeated, under the same conditions. To our surprise, no trace of any microbial contamination is observed. Three possibilities are considered. 1) The factory employed preservative(s) act very efficiently. 2) The shampoo component(s) are themselves bactericidal. 3) Existence of sanitary conditions and the absence of any microbial contaminants at TMU! Evidently, the third possibility is ruled out. The second choice is also discarded, because practically no significant antimicrobial activity is demonstrated by any of the four main ingredients of the shampoos including sodium lauryl ether sulfate (SLES), betaine, coconut fatty acid, and glycerin. Hence, the most likely possibility is the first one, since upon deliberate contamination of the seventeen brands; the factory employed preservatives [5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one (KATHON CG)] prove highly bactericidal against four major contaminants: Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and the methicillin-resistant Staphylococcus aureus (MRSA).
