Ammonium Lactate

Whatsapp Order

Ammonium Lactate is the ammonium salt of lactic acid, appearing as a clear, hygroscopic liquid or syrupy solution. It is widely used in pharmaceutical, cosmetic, and food industries primarily for its moisturizing, pH adjusting, and antimicrobial properties. In topical formulations, it acts as a keratolytic agent to help exfoliate and hydrate skin, making it popular in treatments for dry, scaly, or ichthyotic skin conditions. Its biocompatibility and mild acidic nature make it a versatile ingredient in various industrial and personal care products.

Primary Uses

Pharmaceutical & Dermatological Applications

Used in topical formulations such as creams, lotions, and gels to treat xerosis (dry skin), ichthyosis, and keratosis pilaris.
Acts as a humectant and exfoliant by promoting skin hydration and mild exfoliation of dead skin cells.
Incorporated in moisturizers to improve skin softness and elasticity.
Sometimes used in anti-aging and acne treatment products.

Cosmetics & Personal Care

Added to lotions, body washes, shampoos, and conditioners as a moisturizing agent.
Adjusts pH to maintain skin-friendly levels in formulations.
Enhances product stability and effectiveness.

Food Industry

Occasionally used as a food additive for pH regulation or as a flavor enhancer, though less common than lactic acid itself.
May be found in fermented food processing or preservation.

Secondary Uses

Chemical & Industrial Uses

Used as a pH buffer and stabilizer in various chemical processes.
Can act as a biodegradable acidulant in cleaning and detergent formulations.

Agricultural Uses

Employed in certain formulations for soil pH adjustment or as a biodegradable additive in fertilizers.

Pharmaceutical Manufacturing
