Calcium Lactate
Calcium Lactate is known as Antimicrobial preservative, buffering agent, crosslinking agent, tablet and capsule diluent, tablet binder, tablet filler, therapeutic agent, thickening agent. This product is available in Arvin Kala’s diverse product portfolio.
Description
Calcium lactate occurs as white or almost white, crystalline or granular powder. It is slightly efflorescent.
The structural formula of this substance is as follows:
Calcium lactate is utilized as a bioavailability enhancer and a nutrient supplement in pharmaceutical formulations.
A spray-dried grade of calcium lactate pentahydrate has been employed as a tablet diluent in direct compression systems and has demonstrated good compactability. The pentahydrate form’s properties are considered superior to those of calcium lactate trihydrate in direct compression tablet formulations. The hydration state of calcium lactate and the particle size of the material can influence tablet properties: reducing particle size increases crushing strength, while storing tablets at elevated temperatures leads to dehydration and a subsequent reduction in crushing strength.
Calcium lactate has also been utilized as a source of calcium ions in the preparation of calcium alginate microspheres for controlled release.
Therapeutically, calcium lactate has been employed in formulations for treating calcium deficiency.
