Self-policing has long been the standard for the industry, although
several entities have a say in what constitutes Best Practice in the
manufacturing and production of cosmetics and personal care products. 

The FDA’s  (Federal Food, Drug, and Cosmetics)
oversight is mainly focused on regulating adulterated and misbranded
products. Products classified as improving the appearance and causing a
change (improvement, cure, or prevention/protection), are considered
both a cosmetic and a drug by the FDA and must adhere to more robust
requirements.

FDA's Bacteriological Analytical Manual
(the BAM) states preferred laboratory procedures for the detection in
food and cosmetic products of pathogens (bacterial, viral, parasitic,
plus yeast and mold) and of microbial toxins.

 ISO 22716
is the international standard for the good manufacturing practices
(GMP) for cosmetics, with guidelines accepted by many global regulatory
entities, including the FDA.  The ISO standard focuses on the
production, control, storage, and shipment of cosmetics products.

With roots going back to 1894, the Personal Care Products Council (PCPC)
is , according to their website, “…the leading national trade
association representing cosmetic and personal care products companies
and serving as the voice on scientific, legal, regulatory, legislative
and international issues….”  The council advocates for modernizing
government policies, product safety and sound science, ensuring global
access, and maintaining consumer confidence.
