Example 10

Table 10 below showed that the disinfectant compositions of Formulation DD was obtained at high level of salicylic acid (e.g., above 2% weight based on total weight of the formulation), with high stability and excellent antimicrobial efficacy. The micro efficacy of the disinfectant formulation was determined based on the EPA standard according to the OECD Quantitative Methods for Evaluating the Activity of Microbicides.
