Description
Potassium lactate is a transparent, nearly colorless liquid derived from lactic acid. It is widely recognized for its multifunctional properties, including moisture retention, pH regulation, and antimicrobial performance. It is a key ingredient in food preservation and is also used in pharmaceuticals, cosmetics, and de-icing solutions.
This liquid salt is biodegradable, water-soluble, and non-corrosive, making it a safe and effective component across various industries. It inhibits the growth of harmful microbes while improving texture and shelf life, especially in meat products. Potassium lactate also finds use in sports nutrition, electrolyte solutions, and industrial formulations requiring low-sodium alternatives.
