Micellar water is a nonsterile cosmetic product with water as the main ingredient, which vulnerable to microbial contamination. One of the strategies to protect micellar water products from the risk of microbial contamination is the addition of preservatives. 2-phenoxyethanol has been known as a preservative in the formulation of cosmetic products. Objective: This study aimed to determine the content and effectiveness of 2-phenoxyethanol that is used in the formulation of micellar water products in Indonesia. Methods: The preservative content assay was carried out using a reversephase HPLC instrument. The antimicrobial effectiveness testing was carried out using the principle of challenge test for contamination-free products against five tested microbes. Results: The determination of the 2-phenoxyethanol content in six micellar water products is in a range of 0.551 to 0.767% w/w. The use of 2-phenoxyethanol with a concentration of 0.705% was proven to protect micellar water products from bacterial contamination and the use of 2-phenoxyethanol with a concentration of 0.767% was proven to protect micellar water products from bacterial, yeast, and mold contamination. Conclusions: (1) The content of 2-phenoxyethanol in six micellar water products meet the maximum level required by the Badan POM RI (2) The use of 2-phenoxyethanol with a content of 0.767% w/w proved effective to protect micellar water product from microbial contamination.
