Product Application of L-ASPARTIC ACIDCAS6899-03-2
L-Aspartic acid is a naturally occurring non-essential amino acid that widely distributes in animal tissues, plant sources, sugarcane, sugar beets and molasses. Chemically synthesized L-aspartic acid dominates current industrial and commercial consumption markets compared with natural extracted variants.
In cosmetic raw material field, it is commonly added into skincare formulas targeting dry skin; the ingredient helps optimize skin texture and boost skin smoothness effectively. Besides cosmetic usage, this amino acid also serves as key intermediate raw material for food additives, pharmaceutical intermediates and fine chemical synthesis in multiple downstream manufacturing sectors.
