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.

This article investigates the ability of Zemea (INCI: Propanediol) to boost preservative efficacy in an aqueous personal care formulation. This 100% bio-based propanediol is a colorless, pure glycol alternative derived from a sustainable, renewable corn fermentation process. The testing was conducted using standardized microbiology guidelines, known as preservative efficacy testing or challenge tests.

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.

Straight chain 1,2-alkanediols are multifunctional ingredients with moisturizing and antimicrobial activities. Here, the authors examine the ability of these materials to boost the activity of preservatives and to provide broad-spectrum antimicrobial activity. In addition, the authors describe how to combine these compounds into formulations to optimize stability and efficacy.
