Widely used as a preservative in cosmetics and personal care products due to its strong antimicrobial and antifungal properties. It prevents the growth of bacteria and mold in creams, lotions, shampoos, and makeup, extending shelf life without affecting product texture or scent. Commonly found in water-based formulations where microbial contamination is a concern.

Also popular in certain food industries, such as cheese, butter, and dairy products, to prevent spoilage from mold, especially in high-humidity environments.

Additionally, used in cleaning products or liquids requiring long-term storage to prevent microbial contamination during use.

Further applied in some industrial contexts to protect materials from microbial degradation. Its effectiveness at low concentrations makes it a preferred choice for preserving sensitive formulations.
