Description
L-α-Alanine (CAS 56-41-7) is a non-essential proteinogenic amino acid commonly abbreviated as Ala or L-Ala. It carries no assigned E-code and is not classified as a food additive under EU regulation, though it functions as a nutritional ingredient and formulation component across multiple industries.
In personal care formulations, L-Ala acts as a skin and hair conditioner by supporting the amino acid balance of the stratum corneum and improving moisture retention through humectant activity. In food and pharmaceutical applications, it serves as a buffering agent and mild reducing agent, helping stabilise pH-sensitive systems and protect oxidation-prone actives.
L-α-Alanine is available in food-grade and pharmaceutical-grade forms, with quality benchmarks including FCC and Ph.Eur. monographs. The substance is registered under REACH and supplied as a white crystalline powder. Standard packaging formats include 25 kg bags, with bulk options available on request.
