1. Basic Information
Product Name: ε-Polylysine Hydrochloride
Synonym: ε-Poly-L-lysine Hydrochloride(ε-poly-L-lysine HCl)
Appearance: Light yellow powder with strong hygroscopic properties and a slightly bitter taste.
Solubility: Easily soluble in water.
2. Uses
·Food Preservative: ε-Polylysine Hydrochloride is widely used as a food preservative to extend shelf life. It can inhibit the growth of Gram-positive bacteria, Gram-negative bacteria, fungi, and some heat-resistant spore-forming bacteria. Therefore, it is suitable for various foods, such as fruits, vegetables, beans, edible fungi, rice and rice products, wheat flour and its products, coarse grain products, meat and meat products, seasonings, and beverages.
·Personal Care Products: In the personal care industry, ε-polylysine hydrochloride is used for its broad-spectrum antibacterial properties in products such as toothpaste, mouthwash, soap, hand sanitizer, wet wipes, kitchen cleaners, sanitary pads, and baby diapers to ensure product quality and safety.
·Pharmaceutical Applications: Due to its cationic nature, ε-polylysine hydrochloride has strong electrostatic interactions with anionic substances and good penetration into biofilms, making it useful as a drug carrier. For example, when combined with methotrexate (a drug used to treat leukemia and tumors), it can enhance the drug's efficacy.
3. Characteristics
·High Safety: ε-Polylysine Hydrochloride is completely digestible and absorbable by the human body, breaking down into the essential amino acid lysine with no toxic side effects.
·Broad-Spectrum Antimicrobial Activity: It inhibits the growth of a variety of microorganisms, including Gram-positive and Gram-negative bacteria, fungi, and some heat-resistant spore-forming bacteria.
Minimal pH Impact: ε-Polylysine Hydrochloride retains good antimicrobial activity in neutral and slightly acidic pH ranges.
4. Storage and Shelf Life
·Storage Conditions: Should be stored in a dry, clean, and cool place.
·Shelf Life: Generally two years.
