Science
Mechanism of Action
This modified keratin features aminoethyl disulfide groups, enabling it to form a resilient, moisturizing film on the skin's surface. These disulfide bonds can also re-bond to damaged keratin, enhancing structural integrity and elasticity.

The Formula
Formulation
Stability
Significantly more stable and soluble than unmodified keratin, it performs optimally at pH 6.0-8.0. Maintain temperatures below 60°C and avoid extreme pH to preserve disulfide bond integrity.
Conflicts
- Strong reducing agents (e.g., Sodium Hydrogen Sulfite)
- Strong oxidizing agents (e.g., Hydrogen Peroxide)
- Extreme pH environments (<3 or >12)
Safety
Safety Profile
While often categorized under broader 'Keratin' by CIR, this derivative is generally considered safe for cosmetic use. The inferred maximum concentration of 18% is based on wider amino acid and protein derivative safety data.
