What it is
Sodium Lauroyl Aspartate is an acylated amino acid surfactant formed by combining lauric acid with the amino acid aspartic acid and neutralizing to the sodium salt. It is valued as a mild, skin-friendly surfactant that can serve as a gentle cleanser, an emulsifier, or a dispersing aid for pigments and mineral particles. In sunscreens it often helps disperse UV filters and stabilize the formula.
Safety & warnings
Amino-acid-based surfactants such as Sodium Lauroyl Aspartate are generally regarded as mild and well tolerated, making them common choices for sensitive-skin and gentle formulations.
Origin & sourcing
Synthesized from lauric acid (commonly of coconut or palm origin) and aspartic acid, an amino acid; the resulting acyl amino acid is neutralized with sodium.
