Description
D-Alanine (CAS 338-69-2) is the D-enantiomer of alanine, a non-proteinogenic amino acid also referenced as DAL, D-ALA, or D-Alanin. It carries no assigned E-code and is distinct from its L-form in both biological activity and application profile.
In personal care formulations, D-Alanine functions as a skin and hair conditioner by binding moisture to the stratum corneum and improving texture at concentrations typically between 0.5 and 2%. In pharmaceutical and food applications, it serves as a pH buffer and mild reducing agent, stabilising sensitive active compounds against oxidative degradation.
D-Alanine is available in pharmaceutical-grade (Ph.Eur.-aligned) and food-grade (FCC-compliant) specifications, supplied as a crystalline powder. It falls under HS code 29224900 and is subject to REACH registration requirements within the EU. Standard packaging formats include 1 kg, 5 kg, and 25 kg containers.
