ε-Polylysine hydrochloride has a wide range of applications in daily chemical products, mainly due to its excellent antibacterial properties, thermal stability, broad pH tolerance, and synergistic effects with other additives.
ε-Polylysine hydrochloridee exhibits significant inhibitory effects against both Gram-positive and Gram-negative bacteria, yeast, molds, and other microorganisms. Its broad-spectrum antibacterial activity effectively prevents microbial contamination in daily chemical products and extends the shelf life of these products.
It remains stable at high temperatures (e.g., 121°C for 30 minutes), making it suitable for use in heat-treated daily chemical products, ensuring product safety during production, storage, and use.
ε-Polylysine hydrochloride maintains strong antibacterial activity within a wide pH range of 2 to 9. This makes it applicable to a variety of daily chemical products, including acidic, neutral, and alkaline formulations.
When used in combination with other additives such as acetic acid, ethanol, glycine, and organic acids,ε-polylysine hydrochloride can produce a better antibacterial effect. This synergistic activity makes its use in daily chemical products more flexible and efficient.
Specific Applications:
1. Cosmetics:
ε-Polylysine hydrochloride can serve as a preservative in cosmetics, effectively inhibiting microbial growth and ensuring product hygiene. It can also act as a moisturizer, helping to lock in moisture and maintain skin hydration and elasticity.
2. Oral Care Products:
In oral care products like toothpaste and mouthwash, ε-poly-L-lysine hydrochloride can inhibit harmful bacteria in the mouth, preventing oral diseases. It can be used in combination with fluoride and other ingredients to enhance the effectiveness of oral care products.
3. Personal Care Products:
In personal care products such as shampoos and body washes, ε-polylysine hydrochloride can suppress harmful bacteria on the skin's surface, preventing skin infections. It also helps to clean dirt and oil, keeping the skin clean and comfortable.
4. Other Daily Chemical Products:
ε-Polylysine hydrochloride can be used in disposable hygiene products like wet wipes and tissue papers to prevent microbial contamination and improve hygiene. It can also serve as a preservative in textiles and leather products, extending the lifespan of these goods.
Acute toxicity studies show that the LD50 of ε-polylysine hydrochloride is 5g/kg, similar to that of common table salt, indicating a high level of safety. It breaks down into lysine, an essential nutrient that is absorbed and utilized by the body, posing no harm to human health.
ε-Polylysine hydrochloride has broad application prospects and potential in daily chemical products. Its excellent antibacterial properties, thermal stability, wide pH tolerance, and synergistic effects with other additives make it an indispensable ingredient in daily chemical products.
