North Carolina-based Active Micro Technologies has developed and patented a range of natural multi-functional ingredients combining cosmetic functionality with antimicrobial activity. These include aqueous, oil-soluble, anhydrous and powders.
AMTicide VAF (INCI: Propanediol & Bacillus Ferment & Saccharomyces Ferment Filtrate) was patented on 7 December. It was developed by co-fermenting Bacillus subtilis, a rhizosphere found in many crops, with Saccharomyces boulardii, a probiotic strain of yeast, in a defined growth media. US Patent 11,193,147 describes this as an antimicrobial agent which can prevent or inhibit fungal growth within an area of a closed container housing a product.
“This co-inoculation captures an enhanced production of volatile compounds by the Bacillus cells,” the company said. “Through selective filtration techniques, the volatile organic metabolites are isolated and extracted to deliver a high potency volatile agent that delivers a moisturising and antifungal activity for effective headspace protection.”
