Ammonium lactate is a compound with formula NH₄(C₂H₄(OH)COO). It is the ammonium salt of lactic acid. Has mild anti-bacterial properties.

It has E number "E328" and is the active ingredient of the skin lotions Amlactin and Lac-Hydrin.^[1]

Ammonium lactate is a mix of lactic acid and ammonium hydroxide. It is used as a skin moisturizer lotion to treat dry, scaly, itchy skin. Those who are using it should avoid exposure to sunlight or artificial UV rays, such as sunlamps or tanning beds. Ammonium lactate makes skin more sensitive to sunlight. Skin is more likely to sunburn. Use sunblock and wear clothes when exposed to sunlight.

According to LAC-HYDRIN brand ammonium lactate lotion by Ranbaxy, Inc: "...a long-term photocarcinogenicity study in hairless albino mice suggested that topically applied 12% ammonium lactate formulations enhanced the rate of ultraviolet light-induced skin tumor formation."

Lac-Hydrin specially formulates 12% lactic acid, neutralized with ammonium hydroxide, as ammonium lactate to provide a lotion pH of 4.4-5.5. … 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.
