It is quickly becoming the "go to" test method for evaluating the preservative effectiveness of cosmetics and personal care products. It is intended for water soluble cosmetic products, but can be adapted for products where water is the internal phase.

The ISO preservative efficacy test method is based on the inoculation of a personal care product with a known concentration of 5 relevant strains of microorganisms, specifically S. The remaining concentration of microorganisms is determined at defined intervals during a period of 28 days. For each time and each microorganism, the log reduction or percent reduction is calculated and compared to the acceptance criteria required by the method for acceptable preservation.

Breadcrumb Home. The initial concentration of each microorganism is determined by standard dilution and plating techniques.

At the time of test initiation, a separate aliquot of the product, typically 1 g or 1 ml, is placed in a volume of neutralization broth to be used in the neutralization and recovery validation. The product is held at room temperature for a period of no less than 28 days. The inoculated product is evaluated at 7, 14 and 28 days after inoculation and surviving microorganims are enumerated using standard dilution and plating techniques. Test sample colonies are counted at each specified interval to determine the amount of microorganisms remaining.

The log reduction of each microorganism at each interval is calculated and reported. The effectiveness of the preservative system is determined by comparison to the acceptance criteria. Criteria B: For bacteria, the product must demonstrate no less than a 3 log reduction from the initial count at 14 days and no increase from the 14 day count at day Industry Term.

Safety and Efficacy of Palm-based Ingredients in Cosmetic and Personal Care Products

Cosmetics are required to be safe when consumers use them according to directions in the labeling, or in the customary or expected way. Product testing is just one of the things a manufacturer might do to ensure the safety of a cosmetic product. FDA does not have the legal authority to approve cosmetic products and ingredients other than color additives before they go on the market. We also do not have a list of tests required for any particular cosmetic product or ingredient. However, a manufacturer or distributor of a cosmetic is legally responsible for ensuring that a marketed product is safe when consumers use it according to the directions in the labeling or in the customary or expected way.

All rights reserved. Zoe Diana Draelos, M. Are cosmetics really tested for efficacy? If so, how are they tested? Zoe Diana Draelos answers these questions in this month's Cosmetic Conundrums column. I have been asked many times to write a book chapter or review article on cosmetics citing evidence and rating the evidence for validity and scientific relevance. One such request involved making a list of all the facial moisturizers and then providing the evidence for their efficacy.

When considering the regulation and validation of pharmaceutical products, the efficacy of the active pharmaceutical ingredient API is often the main concern. Ensuring that this compound elicits the appropriate effect at the correct target site is of vital importance. Another regulatory requirement of drug development and manufacturing is guaranteeing that no inappropriate organisms are able to sustain themselves within the product or its packaging. Antimicrobial preservatives are added to pharmaceuticals, medical devices, personal care products, cosmetics and food products to inhibit the growth of micro-organisms inadvertently introduced during the manufacturing process or during the use of products with multiple-dose containers. Preservative efficacy testing PET — also known as antimicrobial effectiveness testing — is undertaken to ensure that the preservative maintains its ability to inhibit micro-organisms and is required by British Pharmacopoeia BP , European Pharmacopoeia Ph. This article will explain the importance of PET for manufacturers, providing examples of when specific challenges to preventing microbial growth might occur and how partnering with testing facilities such as Wickham Laboratories enables companies to comply with international regulations. For example, a topical cream contained in a pot that the user dips their fingers into will be affected differently to a cream contained in a tube applied directly to the skin.

Much like a Preservative Challenge Screen , it is used to evaluate the effect of preservatives in cosmetics, personal care products, and drug products.
