Adding preservatives to personal care products helps control the microbial content, directly impacting product quality, and is necessary to ensure consumer safety, product integrity, and stability. Preservative efficacy testing (PET) confirms that your preservatives are maintaining their ability to inhibit microorganisms introduced to the product during regular or reasonably anticipated use by the consumer and is required by British Pharmacopoeia (BP), European Pharmacopoeia (Ph. Eur.), and the United States Pharmacopoeia (USP).
