Science

Mechanism of Action

Functioning as fundamental building blocks for crucial dermal proteins such as keratin, collagen, and elastin, SODIUM/TEA-LAUROYL KERATIN AMINO ACIDS actively enhance the skin's inherent hydration mechanisms. They fortify the cutaneous barrier, contribute to precise pH regulation, and bolster natural cellular repair processes. Furthermore, they support water retention within the stratum corneum, offer protection against UV-induced damage, and help sustain a balanced skin microbiome. The integrated lauroyl group augments its emollient properties and promotes efficient dermal absorption.

Stability

Generally stable under normal storage conditions; however, it should be protected from excessive heat and moisture. The optimal pH range for applications is typically neutral to slightly acidic, between 5.0 and 7.0.

Conflicts

  • Nitrosating systems (due to the Triethanolamine (TEA) component)
  • Cationic surfactants (common for amino acid surfactants)
  • High temperature and humidity, particularly if the cysteine component is present in salt form

Safety

Safety Profile

CIR Status
Safe with restrictions
Max tested
45%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed SODIUM/TEA-LAUROYL KERATIN AMINO ACIDS safe for use at concentrations up to 45% within cosmetic formulations, provided they are developed to be non-irritating. Due to its Triethanolamine (TEA) content, this ingredient must not be combined with nitrosating systems. Raw materials must meet stringent purity standards, including a minimum 99% purity, a maximum secondary amine content of 0.5%, and a nitrosamine content not exceeding 50 micrograms/kg, stored exclusively in nitrite-free containers.
