Potassium Sorbate from Bio Shop™ is a gentle, food-grade preservative widely used in cosmetic formulations to prevent the growth of mold, yeast, and bacteria. It helps extend shelf life and maintain product freshness in creams, lotions, toners, and serums. Effective in water-based formulations, it’s best used in combination with other preservatives for broad-spectrum protection. Use at 0.1%–0.5% and adjust pH below 6 for optimal performance. Safe for sensitive skin, Potassium Sorbate is ideal for natural and DIY skincare products.
