Vegan USP Testing

  • USP 51 - Antimicrobial Effectiveness Test


    This Vegan friendly edition of United States Pharmacopeia(USP) test is most commonly used for products sold in the United States but is recognised worldwide.

    Unlike a traditional USP Antimicrobial effectiveness test, this adaptation uses animal free products and is approved by The Vegan Society.

  • The United States Pharmacopeia (USP) differs to the traditional European Pharmacopoeia method with the addition of an extra microorganism culture, E. coli. 

    During this antimicrobial effectiveness test, the testing is conducted at 7, 14 and 28 days compared to the traditional European Pharmacopoeia (EP) method where testing is conducted at 2, 7, 14 and28-days. This does make the USP test method less stringent but if you are planning on selling your product within the United States of America this is the minimum required test.

  • When selling cosmetic products, it is crucial to comply with the regulatory requirements of the country in which the product is being sold. For cosmetics, the quality and safety standards are typically determined by one of three major standards: the European Pharmacopoeia (EP), the International Organization for Standardization (ISO), or the United States Pharmacopeia (USP).

    Each of these organisations sets different standards for product testing and quality control, so it is important to choose the appropriate standard for the country in which you are selling your product. For example, if you are selling your product in Europe, you may need to comply with EP standards, while products sold in the US may need to meet USP standards.

    We can offer Vegan Society certified version of the EP, USP and ISO 11930 challenge test methods.
