Physical description & handling notes

• Ammonium lactate appears as white solid or liquid. Has no odor. Sinks and mixes with water. (USCG, 1999)
• Liquid; Liquid; Other Solid
• White solid or liquid; Odorless; [CHRIS] 68-72% Aqueous solution: Light yellow liquid; [PURAC Bioquimica MSDS]
• 1.2 at 59 °F (USCG, 1999) - Denser than water; will sink
• Lactic acid is an alpha-hydroxy acid. It is a normal constituent of tissues and blood. The alpha-hydroxy acids (and their salts) may act as humectants when applied to the skin. This property may influence hydration of the stratum corneum. In addition, lactic acid, when applied to the skin, may act to decrease corneocyte cohesion.
