Natural Preservation in Anti-Aging Cream with Nisin
Introduction: Anti-aging creams are popular in skincare due to their moisturizing, firming, and wrinkle-reducing properties. However, due to their water-based formulations, they are highly susceptible to microbial contamination, which can lead to product spoilage and reduced efficacy. Nisin, a natural antimicrobial peptide, is an excellent choice to extend shelf life and maintain product quality without relying on synthetic preservatives.
Issues
Microbial Contamination: Moisturizing creams are prone to bacterial and fungal contamination, especially after opening.
Short Shelf Life: Without effective preservatives, the shelf life of anti-aging creams can be as short as 6-12 months.
Clean-Label Trend: Consumers are increasingly seeking skincare products with natural and non-toxic preservatives.
Solution: Nisin 0.1%: Nisin was incorporated into the formulation to prevent microbial contamination and extend shelf life without impacting the sensory properties (texture, fragrance, and absorption) of the cream.
Results
Extended Shelf Life: Anti-aging creams with Nisin showed a shelf life extension from 12 months to 18 months, while remaining free from microbial contamination.
No Sensory Changes: The texture and fragrance of the cream remained unchanged, and it maintained its smoothness and hydration properties.
Inhibition of Microbial Growth: Nisin successfully inhibited the growth of common skincare contaminants like Staphylococcus aureus and Candida albicans.
Conclusion: Nisin is an effective, natural preservative in anti-aging creams, extending shelf life while maintaining product quality. Its antimicrobial properties provide a clean-label solution, aligning with consumer preferences for natural skincare products.
