On 18 August 2025, CTPA published an updated version of its guidance on Microbial Quality Management (MQM) for cosmetic products.
The CTPA MQM guidance is intended to assist companies manufacturing cosmetics to put into place an effective programme to ensure the appropriate microbiological quality of their products. It covers all aspects of microbial quality management including product development, water treatment systems, raw materials, manufacturing, housekeeping, cleaning and disinfection and microbiological sampling etc. CTPA teamed up with experts within its membership on Good Manufacturing Practices (GMP) and microbiological quality assessment to update this document, adding new information and offering practical guidance to assist companies in ensuring that products are free from the numbers and types of microorganisms which could affect product quality and safety.
The guidance is available for free to CTPA members; and it is now also available for non-members of the association for a fee of 120£.
