L-aspartic acid
Description
L-Aspartic acid (CAS 56-84-8), also known as L-Aspartate, is a naturally occurring amino acid sourced through fermentation and used across food, pharmaceutical, and personal care manufacturing.
It functions as a pH buffer, chelating agent, and humectant depending on the formulation context. In food and beverage production, it acts as a precursor in the synthesis of aspartame.
It also contributes to flavor profiles in protein hydrolysates. Pharmaceutical manufacturers use it as a mineral carrier in amino acid chelate supplements, where it improves bioavailability of magnesium.
This includes potassium and zinc salts. In personal care formulations, it provides moisture-retention support in skin creams and serums while buffering pH in leave-on products.
It also functions as a sequestrant in industrial and cosmetic formulations where mild chelation of metal ions is required without aggressive chemistry. The material is supplied as a white crystalline powder.
Food-grade material is available to FCC specification, and pharmaceutical-grade supply meets USP and Ph. Eur. standards. Bulk quantities are commonly sourced from fermentation-derived production.
Documentation is available supporting both food and pharma supply chains. This ensures compliance with global regulatory requirements for high-purity chemical distribution and manufacturing.
