Description
Ammonium lactate (CAS 515-98-0) is the ammonium salt of lactic acid, commercially known under trade names including Lac-Hydrin and BMS-186091. It carries no assigned E-code and is classified within the salts and minerals category, supplied as a liquid solution.
In pharmaceutical topical formulations, ammonium lactate functions as a keratolytic humectant, breaking down excess keratin in dry or hyperkeratotic skin while simultaneously drawing moisture into the stratum corneum. In personal care and food applications, it serves as a pH buffer, maintaining target acidity ranges that support preservation and product stability.
Ammonium lactate is available in pharmaceutical-grade liquid form, with compliance referenced against Ph.Eur. and USP monographs depending on end-use requirements. Suppliers operating under REACH must provide a compliant safety data sheet for EU distribution. Procurement teams should confirm concentration grade and packaging format directly with the supplier.
