Formulation Guidelines & pH Recommendations

Optimal Formulation pH Range: Keep the system strictly at pH 6.0 – 6.8. This mimics natural physiological parameters-ideal for sensitive ocular/eye-contour environments-and guarantees the lowest hydrolysis rate for the acetyl group.
Recommended Dosage: 0.5% – 2.0% depending on the targeted efficacy (e.g., 0.5% for preventive daily eye creams; 1.5%–2.0% for professional-grade ophthalmic solutions or intensive night repair serums).
Processing Temperature: Add to the formulation during the final cool-down phase at a temperature below 40°C.
Compatibility Matrix: Fully compatible with Hyaluronic Acid, standard polyols, non-ionic surfactants, and advanced cosmetic peptides. Avoid strong oxidizing or highly alkaline systems.

The Uniqueness: Why Choose N-Acetylcarnosine Over Standard L-Carnosine?

Enzymatic Resistance: The acetyl group protects the peptide backbone from immediate cleavage by systemic carnosinase. This guarantees a controlled, sustained release of the active anti-glycation agent directly in the target tissues.

Advanced Corneal & Dermal Penetration: Due to its amphiphilic properties, NAC demonstrates significantly higher lipophilic affinity than standard carnosine, allowing it to easily pass through lipid-rich barriers such as the stratum corneum and the corneal epithelium.
