NEW!! Zemea® Propanediol May Enhance Efficacy of Preservatives
Skin Irritation and Sensitization

What's New?

Zemea® may enhance efficacy of preservatives!!

Challenge testing was recently conducted with 7 preservative systems that were tested at one-half their recommended use level and evaluated in 4 separate oil-in-water skin care emulsions with varying levels of Zemea® (0.0, 2.0, 4.0 and 6.0 wt%). Zemea® worked well with the Phenoxyethanol-based preservatives against gram-positive, gram-negative, and yeast organisms and had consistent results with each preservative against Aspergillusniger. Zemea® may allow the use of less preservatives in formulations while providing additional performance benefits such as no skin irritation, increased humectancy and excellent aesthetics.
