What is Ammonium Lactate

Lac-Hydrin® 12% is a prescription formulation of 12% lactic acid neutralized with ammonium hydroxide (i.e., ammonium lactate); both a cream and a lotion are available as prescription products for the treatment of ichthyosis vulgaris (hyperkeratotic disorder) and mild to severe xerosis (dry skin).

Lac-Hydrin® 12% cream and lotion also contain mineral oil, propylene glycol, glycerin, cetyl alcohol, and other ingredients.

Lac-Hydrin® 5% is a non-prescription, fragrance-free lotion used to relieve dry skin. It contains ammonium lactate, glycerin, petrolatum, cetyl alcohol, urea, and other ingredients.

The lotion formulation of Lac-Hydrin® 12% was approved by the FDA in April 1985; Lac-Hydrin® 12% cream was later approved in August 1996. Generic versions of 12% ammonium lactate cream and lotion are available.

However, Amlactin® is classified as a cosmetic and has not been shown to be bioequivalent or therapeutically equivalent to Lac-Hydrin®.

Therefore, Amlactin® is not an FDA-approved generic substitute for Lac-Hydrin® 12%.
