Product Description
N-Lauroyl-L-Glutamic Acid, CAS 3397-65-7, is an N-acyl derivative of L-glutamic acid featuring a twelve-carbon lauroyl chain. Also known as Lauroyl Glutamic Acid or N-Dodecanoyl-L-Glutamic Acid, this organic compound combines an amino acid-derived structure with a hydrophobic fatty acyl group.
The molecular structure of N-Lauroyl-L-Glutamic Acid includes an amide linkage and two carboxylic acid groups. These functional groups affect its acid-base behavior, solubility, and interaction with other formulation ingredients. The material is therefore relevant to specialty chemical research and the development of personal care ingredients.
In the cosmetics and personal care sector, Lauroyl Glutamic Acid is associated with amino acid-based ingredient systems and can be evaluated as a formulation ingredient or chemical intermediate, depending on the intended product. It should be distinguished from sodium lauroyl glutamate and other lauroyl glutamate salts, which have different chemical identities and may exhibit different solubility and surfactant properties.
For manufacturers sourcing N-Lauroyl-L-Glutamic Acid CAS 3397-65-7, key selection criteria include assay, appearance, acid value, moisture content, residual impurities, and compatibility with the intended formulation process. The appropriate grade should be selected according to the final application and its relevant quality requirements.
