Description
Choline Bitartrate (CAS 87-67-2) is the tartrate salt form of choline, a water-soluble quaternary ammonium compound. Also referred to as choline tartrate or choline hydrogen tartrate, it carries no assigned E-code and is classified under HS code 29231000 within the amino acids and peptides category.
In personal care formulations, it functions as a humectant and skin conditioner by attracting and retaining moisture at the stratum corneum level, while its buffering capacity helps stabilise product pH within target ranges. In pharmaceutical and nutraceutical applications, it serves as a bioavailable choline source in oral supplements and functional food matrices.
Choline Bitartrate is available in food-grade and pharmaceutical-grade forms, with quality benchmarks including FCC and Ph.Eur. specifications. The substance is registered under REACH and supplied as a white crystalline powder in standard packaging formats suited to industrial procurement volumes.
