Betaine hydrochloride

Betaine hydrochloride (CAS 590-46-5) is the acidic salt form of betaine, supplying hydrochloric acid upon dissolution in water. It is used across pharmaceutical, nutritional supplement, and food processing applications as a controlled acidulant. Buyers sourcing this material should note that it is distinct from anhydrous betaine and delivers measurable acidity alongside the betaine molecule itself. In dietary supplement manufacturing, it is the active ingredient in stomach acid support capsules.

Precise HCl delivery per dose is a key formulation requirement for these products. Food processors use it as an acidulant and buffering agent in products where controlled, gradual acidification is preferred over mineral acids. Pharmaceutical formulators incorporate it into solid dosage forms requiring both pH adjustment and osmolyte activity within the same excipient. This dual functionality makes it a versatile choice for complex chemical formulations.

Personal care manufacturers apply it in scalp and skin formulations where its hygroscopic character supports moisture retention. It helps in maintaining a mildly acidic environment necessary for certain topical applications. Betaine hydrochloride is commercially available as a white crystalline powder. Standard grades include USP, FCC, and technical-grade material, with the food-grade variant being most common for supplement applications.

Bulk supply is typically offered in 25 kg bags for industrial use. High-purity pharmaceutical grades are also available for GMP-compliant manufacturing processes requiring stringent quality control and documentation.
