چکیده مقاله:

Background and Aim:In this study, the effect of different type of alcohol in elimination of microbial contamination in glass cleaner has been investigated. Different formulations have been chosen base on specification table in ISIRI 3305.Methods:Glass cleaner formulations with the different percentage (w/w) of ethanol and isopropanol with total 10% (w/w) prepared, and with blend of microorganism Escherichia coli , Pseudomonas aeruginosa , Candida albicans contaminated. After that samples were studied with test method base on ISIRI 11804 and ISIRI 5875.Results:Results show that isopropanol in glass cleaner with the Lowers percentage have the highest effect in elimination of microbial contamination. Also blend of ethanol and isopropanol in glass cleaner formula are more effective than ethanolic glass cleaner in elimination of microbial contamination. Ethanolic formulations with lower than 10 percent ethanol need preservative for elimination of microbial contaminationConclusion:As regards in reversion of ISIRI 3305, the solvent concentration was reduced from 15% to 9% . This study was demonstrated, it is not necessary using of preservative for controlling the microbial contamination at 15% dosage of ethanol. Because of using glass cleaner for cleaning accessible glassy surface, it is necessary to produce this kind of detergent without any contamination. Base on this study microbial check in the standard test method of this product is suggesting.
