Nonapeptide-1 is a high-purity cosmetic peptide powder for alpha-MSH/MC1R-pathway brightening, uneven tone, and visible spot-appearance formulas.

Physical form: This product is supplied as a freeze-dried powder.

Nonapeptide-1 is commonly positioned as an alpha-MSH antagonist peptide, making it a strong active story for formulas that target melanin signaling, dullness, uneven tone, and localized dark-spot appearance. It is best used in leave-on serums, gels, creams, masks, and targeted tone-correcting products.

Product Description: Use Nonapeptide-1 when the formula needs a modern peptide brightening story beyond conventional acids and botanical extracts. The powder format gives formulators full control over stock solution concentration, pH, preservative system, peptide recovery, and final texture.

Usage: Brightening serums, tone-evening gels, creams, lotions, masks, spot-care products, and targeted leave-on peptide treatments.

Mixing method:

- Pre-dissolve in purified water, water/propanediol, water/butylene glycol, or water/glycerin before adding to the main batch.

- Add at the final step during cool-down when the formula is below 40°C. Avoid hot emulsification, hot-fill processing, and prolonged heating.

- Recommended finished-product pH is 5.0-7.0.

- Confirm clarity, preservative compatibility, peptide recovery, color stability, and irritation profile in the final formula.

Usage rate: 0.001-0.01% pure peptide powder. Start at the low end for first prototypes and adjust by assay, stability, irritation, and claim substantiation.

Product characteristics: white to off-white cosmetic peptide powder.

Solubility: Best handled through a water/glycol stock solution; dispersible in cream or gel bases. Do not assume direct oil solubility without validation.

Storage: Store tightly closed, protected from moisture. Keep refrigerated at 2-8°C for long-term storage; avoid repeated opening and freeze-thaw cycling.
