The preservatives traditionally used in the cosmetics such as parabens are regarded as a component to be eliminated because of their harmful properties. Nonetheless, the addition of anti-microbial agents is unavoidable to prevent the microbial contamination. Alkane diols, one of the widely used moisturizing components of cosmetics, are now used as the alternative of anti-microbial agents. In this work, alkane diols such as 1,2-pentanediol, 1,2-hexanediol, 1,2-octanediol and phenoxyethanol were tested to determine their anti-microbial activity and the possibility to be used as the preservatives in the cosmetics. The inhibition of microbial growth with single alkane diol was not strong enough except the 1,2-octanediol, which could weakly inhibit the four tested microorganisms including E. coli, P. aeruginosa, S. aureus, C. albicans . For this reason, each alkane diol and phenoxyethanol combination is not suitable for the cosmetic preservatives. On the other hand, the combined three chemicals, 1,2-hexanediol (0.3%), 1,2-octanediol (0.3%) and phenoxyethanol (0.3%) could successfully inhibit the growth of the four microorganisms and this was confirmed by applying them to the cosmetic emulsion and showing that a 3 log reduction of microorganism was possible. On the basis of these results, the combination of alkane diols with phenoxyethanol could be used as a good alternative of cosmetic preservatives.
