Description of Anti-yeast: anti-yeast agents are a kind of antimicrobial ingredients or chemicals that specifically target yeasts. Yeasts are single-celled microorganisms belonging to the fungus family. While some yeasts are beneficial and important for human health, other yeasts can cause significant infections and pose a serious risk to the human health. Yeasts also form a risk for the quality of Food and Personal Care products. Yeasts can metabolize the formulation, leaving behind spoiled material. Common preservatives are sometimes ineffective against yeast proliferation. For this reason, it is important to incorporate in formulations that are vulnerable to yeasts, specific anti-yeast preservatives, such as Ingrephen BWPS, PDI Plus Liquid or Ingrephen PBD.
