Preservative Efficacy Testing (PET)

At GLOW ESSENTIALS , we put safety first. That's why we highly recommend you doing PET before launching your products to ensure products safety and avoid costly recalls. We partner with trusted labs in Southern California and New Jersey to perform preservative efficacy tests, including USP <61> and USP <62>. Your formulas will be challenged by disease-causing microorganisms, bacteria, yeast and mold to determine growth and preservative system efficacy. The test runs about 8 weeks (Prep +Transit: 2weeks, Testing 4weeks, Reporting 2 weeks)
