Sodium Lactate 60%
Sodium Lactate 60% is a clear to slightly yellowish, viscous liquid obtained by neutralizing lactic acid with sodium hydroxide. It is widely used as a food additive, pharmaceutical excipient, and in cosmetic formulations due to its humectant, buffering, and antimicrobial properties. This grade is valued for its ability to retain moisture, regulate acidity, and act as a preservative in various industries. It also finds applications in the medical field as an electrolyte replenisher and pH stabilizer.
