Microbial contamination in the cosmetic industry has attracted attention because it risked human health. We examined the effect of preservatives such as 1,2-hexanediol (H), 1,2-octanediol (O), 4-hydroxy acetophenone (A), and their combinations in preventing microbial contamination and reducing the viscosity drop of CNF suspensions. Antimicrobial activity was evaluated by colony count method for B. subtilis , S. xylosus, C. albicans, and the percentage of contaminated area for A . niger . CNF viscosity was measured using a rheometer. The viscosity of CNF was drastically diminished by decreasing the concentration of preservatives used in the suspension. 1,2-hexanediol was the most effective in inhibiting the growth of B . subtilis and S . xylosus at the lowest concentration (0.25%). 4-hydroxy acetophenone was able to reduce CNF degradation by B. subtilis and S. xylosus, more effective than other preservatives. 1,2-octanediol was the most powerful in preventing the growth of C . albicans and A . niger . It was also able to reduce the degradation by C . albicans to 18.96%, followed by O+A and H+O at the concentration of 2%. In the case of A. niger, H+O and H+A presented the interesting results to decrease CNF degradation of 38.32% and 39.21%, respectively.
