Science
Mechanism of Action
This ingredient operates by significantly reducing the surface tension of water, thereby facilitating the efficient emulsification and removal of impurities, dirt, and excess oil from both skin and hair. Its unique structure allows it to maintain skin's integrity while cleansing, and it possesses the additional benefit of mitigating the potential for irritation often associated with more aggressive anionic surfactants, such as SLS or traditional fatty acid soaps.

Stability
Potassium Lauroyl Glutamate demonstrates robust stability within formulations formulated between a pH of 4.5 and 8.5. Consistent with other amino acid-derived surfactants, it requires proper preservation to prevent microbial contamination. It exhibits moderate tolerance to both salt and hard water conditions.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Potassium Lauroyl Glutamate, along with a group of 115 related amino acid alkyl amides, is safe for use in cosmetic products under current practices and concentrations, provided the final formulation is non-irritating. Data from a related ingredient, sodium lauroyl glutamate, showed no dermal irritation in human studies at concentrations up to 10% and no ocular irritation at up to 5% in in vitro studies, despite being a mild irritant at 5% in rabbits.
