Literature/Data
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.
Preservation
The Importance of Formaldehyde-Donor Preservatives in Personal Care Products
Preservatives are critical ingredients in personal care products and cosmetics, where they help to ensure consumer safety as well as product performance and stability. Among these materials, formaldehyde-donor (FD) preservatives have demonstrated a long history of safe and effective use for controlling microbial growth.

Sun Care
Preserve and Protect: Shielding the Sunscreen Umbrella
The sunscreen market is trending toward higher SPF levels, but these formulas tend to be more difficult to preserve. This study shows how high-SPF sunscreens can be adequately preserved using nontraditional approaches combining antimicrobials and multifunctional additives with boosting aids.

2005 Preservatives Use: Frequency Report and Registration
The U.S. Food and Drug Administration (FDA) compiles frequency of use data from registrations submitted through the Voluntary Cosmetic Registration Program (VCRP). Here, a review of the latest preservative data collected is presented as well as a discussion of the importance of the registration program.

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.

Water Activity Strategy Boosts Microbial Stability and Barrier Function
Work published in
Cosmetics
outlines how reducing water activity in o/w emulsions by using natural humectants can provide a formulation preservation strategy while improving the skin's barrier function.
Preservation
Alternative Preservation for Wet Wipes and Cold Process Cosmetics
Hurdle technology is a holistic formulation approach that assesses the impact of multiple factors on the ability of a formulation to support microbial growth. A particular challenge has been the identification of ingredients that can be used in the hurdle technology approach for solutions and emulsions in non-woven substrates, and INOLEX has created two ingredients to help formulators address this need.
