Demonstration of lower efficacy of organic preservative compared to synthetic formulations using the example of a cosmetic emulsion.

Preservatives are chemical substances used in many industries to ensure the shelf life of products by inhibiting the growth of microorganisms. This study aimed to determine the effectiveness of natural plant-based substances as preservatives in emulsions, compared to synthetic preservative systems. Based on the research, it can be concluded that the most effective preservative was a synthetic preservative with INCI: Benzyl Alcohol, Dehydroacetic Acid, and Aqua. Additionally, airless packaging provides better product protection against microorganisms.
