Microbiological Considerations for Refillable Bulk Cosmetics: Survey and Commentary

The commercial sale of refillable products in bulk now includes liquid galenic formulas. Their diverse flow chains pose unique microbial challenges, as shown here, underlining the importance of flow chain planning and assessment tools/strategies.

Caprylyl Glycol/Phenethyl Alcohol Blend for Alternative Preservation of Cosmetics

In recent years, the safety of traditional preservatives has been called into question. Therefore, there is a need for alternatives that are effective, safe and sustainable—and that are non-controversial. In response, the present work investigates a mixture of caprylyl glycol and phenethyl alcohol, which is shown to provide antimicrobial activity in various skin and hair care formulations.

Proposed Method to Evaluate the Microbiological Stability of Cosmetics During Use

The authors propose an approach to assess the microbial stability of a product during use, referred to as the Microbiological Use Test (MUT), and apply this analysis in case studies to predict the microbiological risk of commercial products. The described test has been used successfully in the development of cosmetics.

Preservative Efficacy Testing of Aqueous Cosmetics and Drugs without Counting Colonies

A miniaturized system using broth enrichment followed by either streaking on agar or fluorescence treatments can eliminate colony counting in the linear regression method of preservative efficacy testing.

Multifunctional Cosmetic Ingredients as Antimicrobials

Today's formulator is busy, and their task of creating innovative formulations is boosted by new multifunctional ingredients. The concept of delivering two highly desired benefits for personal care in one product is one of great appeal to formulators globally.

Ingredient Profile—Benzoic Acid/Sodium Benzoate

Benzoic acid (BA) is a leading choice due to its long and successful history of use preserving foods, drugs and cosmetics. Affirmed as GRAS (Generally Recognized As Safe) by the US Food & Drug Administration (FDA), BA and its sodium salt, sodium benzoate (NaB), are perhaps the most globally acceptable preservatives that have managed to avoid the controversy associated with many of the industry’s tried-and-true preservatives.

Natural Preservation from Concepts in Nature

Chemical defense mechanisms used in the plant kingdom are the basis of natural antimicrobials with multifunctionality for preservation of cosmetic formulations. Two examples are organic acids and glyceryl monoesters.

Ingredient Profile—Sorbic Acid/Potassium Sorbate

SorbH and KSorb have become increasingly popular options for cosmetic preservatives due to their worldwide status as Generally Recognized As Safe (GRAS) food ingredients and their long and successful use history.

Preservative Predicaments in Facial Skin Care

Preserving skin care products has become challenging because of attacks by special interest groups, which often lead to negative consumer perceptions. As these assaults on preservatives—some scientifically sound, some not—continue, the industry must look for new preservation methods to gain acceptance.

The Safety Factor in Preservative Efficacy Testing

The authors explain how preservative efficacy testing is done to determine whether a formula is adequately preserved. Product contamination problems are frequently caused by inadequate preservation.
