Whatsapp Order

Potassium Lactate is the potassium salt of lactic acid, typically available as a clear, colorless to pale yellow liquid or solid powder. It functions primarily as a food additive, humectant, and preservative with antimicrobial properties. Widely used in the food industry, it also finds applications in pharmaceuticals, cosmetics, and industrial processes. Potassium Lactate helps improve moisture retention, extend shelf life, and enhance safety by inhibiting microbial growth.
