TEA-LAUROYL KERATIN AMINO ACIDS.

Valuable / ANTISTATIC, CLEANSING, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING

TEA-Lauroyl Keratin Amino Acids is a meticulously modified amino acid derivative sourced from keratin, designed to enhance solubility and optimal skin penetration. It functions as a conditioning agent, aiding in skin hydration, strengthening, and repair by forming a protective protein film, thereby supporting skin resilience and overall dermal health.

Summary

Skin Conditioning Cleansing Surfactant

Science

Mechanism of Action

This ingredient delivers specialized keratin amino acids to the skin, where they work to optimize hydration and cellular function. It reinforces the skin's natural barrier and creates a lightweight protein film on the surface, which assists in moisture retention and shields against external stressors, leading to noticeable improvements in skin texture and elasticity.

Stability

This ingredient demonstrates reliable stability under typical storage conditions. It is essential to protect it from excessive heat and moisture to maintain its integrity. Optimal performance and stability are achieved within a physiological pH range of 5.0 to 7.0, which is well-suited for skin applications.

Conflicts

  • Cationic surfactants
  • N-nitrosating agents (due to TEA component)

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed amino acid alkyl amides, including TEA-Lauroyl Keratin Amino Acids, safe for use in cosmetics when formulated to be non-irritating. However, as it contains Triethanolamine (TEA), a known concern for potential nitrosation exists; thus, it must not be combined with N-nitrosating agents. An older CIR report from 1983 advises that for products intended for prolonged skin contact, the concentration of ethanolamines should not exceed 5%.

Verdict

Valuable

TEA-Lauroyl Keratin Amino Acids offers valuable conditioning and moisturizing benefits as a gentle surfactant, though its formulation demands careful consideration to mitigate potential irritancy and nitrosation risks associated with its TEA component.
