Usage

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.

PROCESS FOR PRODUCING A LACTIC ACID-AMINE COMPLEX

A process for the production of a complex of lactic acid and either ammonia or an amine, comprising: a) reacting a stream rich in saccharide with sodium hydroxide to produce a reaction mixture comprising sodium lactate; b) contacting at least a portion of the 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 sodium carbonate and/or bicarbonate and a stream rich in said complex; c) reacting at least a portion of the sodium carbonate and/or bicarbonate with an alkaline earth metal hydroxide to produce sodium hydroxide and alkaline earth metal carbonate, wherein the alkaline earth metal is selected from the group consisting of calcium and magnesium; and d) recycling at least a portion of the sodium hydroxide produced in step c) to step a).

Process for Producing a Lactic Acid-Amine Complex

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.

Reactive Extraction of Free Organic Acids from the Ammonium Salts Thereof

The invention relates to a process for converting ammonium salts of organic acids to the particular free organic acid, wherein an aqueous solution of the ammonium salt is contacted with an organic extractant and the salt is dissociated at temperatures and pressures at which the aqueous solution and the extractant are in the liquid state, and a stripping medium or entraining gas is introduced in order to remove NH3 from the aqueous solution and transfer at least a portion of the free organic acid formed to the organic extractant. The invention described here thus provides an improved process for releasing an organic acid, preferably a carboxylic, sulphonic or phosphonic acid, especially an alpha-hydroxycarboxylic acid or beta-hydroxycarboxylic acid, from the ammonium salt thereof by release and removal of ammonia and simultaneous extraction of the acid released with a suitable extractant from the aqueous phase. This process corresponds to a reactive extraction. The reactive extraction of an organic acid from the aqueous ammonium salt solution thereof can be improved significantly by the use of a stripping medium or entraining gas, for example nitrogen, air, steam or inert gases, for example argon. The ammonia released is removed from the aqueous solution by the continuous gas stream and can be fed back into a production process. The free acid can be obtained from the extractant by a process such as distillation, rectification, crystallization, re-extraction, chromatography, adsorption, or by a membrane process.

PRODUCTION OF LACTIC ACID

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.

This invention relates to an acidic non-irritating lotion, cream or ointment for rejuvenating skin and hair which comprises a micronized, homogenized hydrogel of a crosslinked N-vinyl lactam polymer and an organic rejuvenating agent selected from the group consisting of pyruvic acid, a mono- or poly-carboxylated C1 to C20 hydrocarbon optionally substituted with from 1 to 3 hydroxy groups and ammonium and alkali metal salts of said acids and mixtures thereof including mixtures of the acids and/or said salts.

Process for preparation of stable aqueous solutions of zirconium chelates

Aqueous solutions of zirconium chelates are prepared by combining an alpha-hydroxycarboxylic acid salt with a solution of a zirconium compound. That preparation first involves formulating an alpha-hydroxycarboxylic acid salt through a stoichiometric reaction between an alpha-hydroxycarboxylic acids and a base. The stoichiometric reaction product consists of an approximately neutral solution of a corresponding alpha-hydroxycarboxylic acid salt. The alpha-hydroxycarboxylic acid salt is then added to a solution of a zirconium compound to produce a mildly acidic or basic solution of the corresponding zirconium alpha-hydroxycarboxylic chelate. Alternatively, the alpha-hydroxycarboxylic acid salt may be pre-prepared and added in solid or liquid form to the zirconium compound before the zirconium compound is placed in solution so that the corresponding zirconium alpha-hydroxycarboxylic chelate is produced.

Process for preparation of stable aqueous solutions of zirconium chelates

The present invention comprises reacting ammonium, sodium or potassium hydroxide or water soluble amines or amine derivatives with alpha-hydroxy carboxylic acid to prepare a neutral solution of the corresponding alpha-hydroxy carboxylic salt in a stoichiometric reaction. The alkali metal, ammonium, amine or amine derivative, alpha-hydroxy carboxylic acid salt is then added to solutions of zirconium which may be zirconium oxychloride, zirconium hydroxy chloride, zirconium acetate and the like, ammonia, water soluble amines or amine derivatives, diisopropylamine or a mixture of two or more of these bases, as well as soluble carbonates and/or bicarbonates of ammonium and alkali metals such as sodium and potassium, while mixing the solutions. The procedure produces a mildly acidic or basic solution of the zirconium alpha-hydroxy carboxylic chelate.
