Detailed Analysis
Yeast (Saccharomyces cerevisiae, CAS 68876-77-7) is a single-celled fungus used in cosmetics as a skin-conditioning agent. It contains a rich complex of B vitamins (niacinamide, riboflavin, thiamine), amino acids, beta-glucans, glutathione, and minerals. These components support cellular energy production via ATP synthesis, provide antioxidant protection, and promote skin repair. The CIR Expert Panel has concluded that yeast-derived ingredients pose minimal risk under normal use conditions. Commonly used at concentrations up to 5% in leave-on and rinse-off products.
