In the field of daily chemicals, the use of preservatives is crucial, as they can protect cosmetics from microorganisms. ε-polylysine and nisin are both polypeptide preservatives with natural, safe and efficient properties. However, in terms of antibacterial range, E-polylysine has shown wider application prospects. As a natural preservative, nisin mainly shows good antibacterial effects on Gram-positive bacteria, but its effect on Gram-negative bacteria and Escherichia coli is not obvious. This limitation limits the application of nisin in some daily chemical fields.

Product advantages of polylysine

In contrast, ε-polylysine breaks this limitation. It can not only effectively inhibit the growth of Gram-positive bacteria and Gram-negative bacteria, but also exhibits significant bacteriostatic and killing effects on Escherichia coli, Arthrobacter and the like. This feature allows ε-polylysine to have a wider application space in the field of daily chemicals, especially in products that need to fight against both Gram-positive and Gram-negative bacteria.

In addition to its wider antibacterial range, Ahualyn ε-polylysine has many other advantages. For example, it has good water solubility and stability. At the same time, ε-polylysine also has high heat resistance (120°C for 20 minutes) and can not be damaged during high-temperature sterilization.

In summary, ε-polylysine stands out for its broad-spectrum antibacterial effect, showing powerful bactericidal effects on Gram-positive and -negative bacteria, yeasts, molds, and viruses. This feature makes the application of ε-polylysine in the field of daily chemicals more potential, providing a strong guarantee for the safety and quality of cosmetics.

Applications of polylysine

In cosmetics, polylysine as a preservative has been included in China's "Catalogue of Names of Used Cosmetic Raw Materials". In view of its good antibacterial properties and safety, cosmetic companies in South Korea, Japan, Europe and the United States have used polylysine as a preservative in some lotions, creams, lotions and makeup removers. As a safe, environmentally friendly, efficient and broad-spectrum fungicide, polylysine will have a large application space in the daily chemical industry. In addition, ε-polylysine has strong hygroscopicity and can be used as a moisturizer in cosmetics. It can also be combined with propylene glycol to form a hydrogel to prepare highly water-absorbent polymer materials for use in disposable diapers. and sanitary napkins and other daily chemical products.
