AI Technical Summary
There is no universal antimicrobial agent that effectively inhibits a wide spectrum of bacteria, yeast, and mold, and existing agents like parabens face safety concerns, necessitating the development of multifunctional, natural compounds for various formulations.
A mixture comprising at least two of the following compounds: a pyrone derivative, a tropolone derivative, a phenylpropanoid, a mono- or sesquiterpene, an aromatic acid or salt, and an alkanediol, which exhibit synergistic antimicrobial properties against microorganisms like Staphylococcus aureus, Candida albicans, and others, and can be naturally derived or synthetically obtained.
The synergistic mixtures provide strong antimicrobial effects, are well-tolerated for skin use, and offer additional cosmetic benefits, making them suitable for pharmaceutical, cosmetic, personal care, animal care, and cleaning formulations.
