Description
2-Hydroxypropanoic acid monoammonium salt, also known as ammonium lactate, is an ammonium salt of lactic acid with the chemical formula NH4(C2H4(OH)COO). It is recognized by the E number "E328" and is a key component in various skin care products, including Amlactin and Lac-Hydrin.
Uses
Used in Pharmaceutical and Cosmetic Applications:
2-Hydroxypropanoic acid monoammonium salt is used as an active ingredient in skin care products for its ability to thicken the viable epidermis and reduce the thickness of the stratum corneum layer. This neutralized version of lactic acid provides moisturizing and exfoliating benefits to the skin.
Used in Industrial Applications:
2-Hydroxypropanoic acid monoammonium salt is used as a feedstock for the production of ethyl lactate, which is a bio-sourced and biodegradable cleaning fluid with excellent solvent properties. It has found widespread use in the manufacturing of specialty coatings and inks, contributing to environmentally friendly solutions in various industries.
Used in the Production of Lactate Esters:
In the fermentation process, ammonium lactate is produced and then thermally and catalytically cracked to generate lactic acid. This lactic acid, when combined with an alcohol, forms the ester. The ammonia and water byproducts are separated through a selective membrane and recycled, making the production of lactate esters economically competitive.
Used in Electrodialysis:
Ammonium lactate solution has been utilized in the ammonium lactate fermentation broth for the concentration of organic acid salts by conventional electrodialysis (EDC), which is a process that enhances the efficiency of producing valuable organic compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 515-98-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 515-98:
(5*5)+(4*1)+(3*5)+(2*9)+(1*8)=70
70 % 10 = 0
So 515-98-0 is a valid CAS Registry Number.

Process for Producing a Lactic Acid-Amine Complex
-
Paragraph 0047, (2013/08/14)
A process for the production of a complex of lactic acid and either ammonia or an amine, comprising reacting one or more saccharides with barium hydroxide to produce a first reaction mixture comprising barium lactate, and contacting at least part of the first reaction mixture with ammonia or an amine and with carbon dioxide, or with the carbonate and/or bicarbonate salt of ammonia or an amine, to produce a second reaction mixture comprising said complex and barium carbonate.
PRODUCTION OF LACTIC ACID
-
Page/Page column 8-9, (2008/06/13)
There are disclosed methods for producing lactic acid that comprise fermentation of a sugar to produce a lactate, optionally a salt swapping process to produce an ammonium lactate or akyl ammonium lactate, an extractive salt splitting process to produce a lactic acid loaded extractant, and separation of lactic acid by water back extraction or by direct distillation.
