The Cosmetic, Toiletry, and Fragrance Association (CTFA) is requesting public comments by March 30, 2007 on the new microbiology method “M-7: A Rapid Method for Preservation Testing of Water-Miscible Personal Care Products."
This procedure allows the rapid determination of preservative performance in water-miscible personal care products. This procedure is intended to be used as a screening test during product development. It can quickly differentiate between preservative systems that may be capable of providing adequate preservation and those which have insufficient anti-microbial activity to protect the product. It is not intended to provide the definitive information on the adequacy of preservation of the final formulation. This method will be included in the 2007 update of the CTFA Microbiology Guidelines that are part of the CTFA Technical Guidelines series.
Each method undergoes an extensive development and review process by CTFA technical committees and staff, as well as public review by CTFA member companies, nonmember companies, federal government agencies, and scientific professional societies.
The CTFA is also requesting public comments by March 30, 2007 on the new microbiology guideline “M-6: A Method for Preservation Testing of Atypical Personal Care Product."
This method represents industry practice as an acceptable procedure for determining the preservative efficacy of atypical cosmetic and toiletry formulations such as oils, powders, or other formulations that have low water content and/or are not miscible with water. It reflects an approach to preservative challenge testing currently used in the personal care products industry. This method will be included in the 2007 update of the CTFA Microbiology Guidelines that is part of the CTFA Technical Guidelines series.
Each method undergoes an extensive development and review process by CTFA technical committees and staff, as well as public review by CTFA member companies, nonmember companies, federal government agencies, and scientific professional societies.
An electronic copy of the draft guidelines is available from the CTFA Public Affairs Department by contacting Jill Marvin at marvinj@ctfa.org.
