Broad-Spectrum Microbial Protection in Moisturizing Lotion with ε-Polylysine

Introduction: Moisturizing lotions are essential in daily skincare routines, but their high-water content makes them prone to microbial growth, including bacteria and fungi. Adding ε-Polylysine to the formulation provides broad-spectrum microbial protection, ensuring product safety and extending shelf life without the use of synthetic preservatives.

Issues

Microbial Contamination: Water-based lotions are prone to bacterial and fungal growth, especially when stored for long periods or exposed to air.

Shelf Life: Without preservatives, lotions have a relatively short shelf life of 6-12 months before becoming contaminated.

Consumer Demand: There is a growing trend toward clean-label, natural products, and preservative-free formulations

Solution: ε-Polylysine 0.1%: ε-Polylysine was added to the lotion to provide antimicrobial protection against common skin contaminants like Escherichia coli, Staphylococcus aureus, and Candida albicans.

Results

Inhibition of Microbial Growth: ε-Polylysine successfully prevented microbial growth for 12 months, ensuring the lotion remained safe to use.

Extended Shelf Life: The shelf life of the moisturizing lotion was extended from 6 months to 18 months.

No Sensory Impact: The lotion retained its smooth texture, hydrating properties, and natural scent, with no alterations to its consistency or fragrance

Conclusion: ε-Polylysine is an ideal natural preservative for moisturizing lotions, providing effective microbial protection and extended shelf life. It aligns with consumer demand for safe, preservative-free skincare products
