Industrial Applications of L-Lysine 50% Solution (CAS 56-87-1)

L-Lysine 50% Solution (CAS 56-87-1) is a 49–51% aqueous solution of the essential amino acid L-lysine, supplied by Nexal Inc. as a colorless to pale yellow liquid under cold-chain (2–8 °C). The applications described below reflect long-established, public-domain uses of liquid L-lysine across the feed, food, and industrial sectors. Material is supplied for industrial and research use; the buyer is responsible for verifying suitability for the buyer's specific application.

• Liquid Feed Dosing & Animal Nutrition

Liquid L-lysine has been used in commercial feed manufacturing for several decades as an alternative to crystalline lysine, allowing direct in-line metering into liquid feed systems and eliminating powder dust during plant operations. The 50% concentration is a class of product that has been established in the feed industry for many years.

End Products: liquid feed premix lines, in-line amino acid dosing systems, custom liquid feed blends, swine and poultry liquid feeding programs, aquaculture liquid feed formulations.

• Food & Beverage Ingredient Applications

Aqueous L-lysine solutions are used as a fortification ingredient in liquid food and beverage manufacturing where a pre-dissolved amino acid source is operationally preferred over crystalline material. Buyers using the material in food applications are responsible for confirming that their finished product meets all applicable food regulations in their jurisdiction.

End Products: fortified beverage premixes, liquid food ingredient blends, in-process food fortification streams, plant-based protein beverage formulations.

• Industrial Formulation & Research Use

The pre-dissolved liquid format is convenient for laboratory and industrial chemistry where an aqueous L-lysine source at known concentration is required. Because the solution contains the free-base form, it provides an alkaline-to-neutral pH lysine source without introducing chloride counter-ions into the formulation.

End Products: cosmetic and personal-care raw material blends, industrial fermentation supplementation, analytical reference solutions, custom research formulations, chloride-free amino acid stock solutions.

Pre-Dissolved Liquid Format: The 50% aqueous solution eliminates the powder dissolution and dust-handling steps required when working with crystalline L-lysine, supporting in-line dosing, automated metering, and reduced operator exposure to fine particulates in plant environments. Cold-chain storage (2–8 °C) is required.
