New consumer moisturisation and sensory testing has shown that by using a blend of Zemea and glycerin in a lotion formulation it is possible to improve the consumer perceived aesthetics without compromising hydration performance.
The objective of this study was to determine if Zemea® Propanediol could improve consumer sensory perceptions of a typical high moisturising lotion based on glycerin while maintaining satisfactory humectancy performance. The generic lotion containing 20 wt.% glycerin was compared to both a lotion with 20 wt.% Zemea, and a lotion using a blend of Zemea/glycerin (10 wt.% each). This study used Corneometer assessments of skin hydration and consumer sensory evaluations. The subjects of the study were 6 male and 23 female healthy volunteers between the ages of 19 and 66 who use moisturising lotion on a daily basis. The study was conducted by Princeton Consumer Research, Princeton, NJ, US on behalf of DuPont Tate & Lyle Bio Products Company, LLC.
Previous studies have been conducted to evaluate the moisturisation efficacy and consumer sensory perceptions of various formulations containing Zemea propanediol (now referred to as ‘biobased propanediol’), glycerin and/or other diols:
In the current study, we evaluated the moisturisation values and consumer sensory perceptions of three high moisturising formulations that contained either:
