l-Carnitine l-tartrate

L-Carnitine L-Tartrate (CAS 36687-82-8) is the tartrate salt form of L-Carnitine, also marketed under the trade name Carnipure Tartrate. It carries no assigned E-code and is classified under HS code 2923.90.0100. The compound is recognised in the amino acids and peptides category and is sometimes referred to as Vitamin BT L-tartrate.

In cosmetic formulations, L-Carnitine L-Tartrate functions as a humectant by attracting and retaining moisture within the skin matrix, and as a skin conditioner that supports barrier integrity. In food and nutraceutical applications, it serves as a bioavailable carnitine source, while its buffering capacity allows formulators to stabilise pH in aqueous systems without additional acidulants.

The material is supplied as a crystalline powder meeting food-grade and cosmetic-grade specifications, with compliance applicable under REACH regulation for EU market supply. Procurement teams should confirm grade suitability against FCC or Ph.Eur. standards depending on the target application. Standard packaging formats include fibre drums and multi-layer bags.
