Question

Are Sodium Lauroyl Glutamate and Lauroyl Glutamic Acid the same ingredient? I am also asking about the products with ID 513 and ID 214.

Answer

Yes, as the staff replied, Sodium Lauroyl Glutamate and Lauroyl Glutamic Acid are different substances.

  • Lauroyl Glutamic Acid is the acidic form. It is an amino acid derivative.
  • Sodium Lauroyl Glutamate is the sodium salt of Lauroyl Glutamic Acid. This means the acidic proton has been replaced by a sodium ion.

This difference in chemical structure (acid vs. salt) results in different properties. Sodium Lauroyl Glutamate is commonly used as a mild anionic surfactant in cleansers due to its solubility and ability to create foam, while Lauroyl Glutamic Acid may have different applications or require neutralization in a formulation.

The product you linked with ID 513 is Sodium Lauroyl Glutamate. The product you linked with ID 214 is named "Natural Moisturizing Amino Acids", which is a different product name than Lauroyl Glutamic Acid, although it might contain it or be related.
