Tetrapeptide-30 is a high-purity cosmetic peptide powder for brightening, uneven tone, dullness, and post-blemish spot appearance formulas.

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

This peptide is positioned upstream of melanogenesis signaling, making it a useful active for formulas that target a more even-looking complexion and reduced visible discoloration. It fits daily brightening serums, spot-care gels, tone-evening creams, masks, and post-blemish skincare routines.

Product Description: Use Tetrapeptide-30 when the formula needs a modern peptide brightening story that feels more advanced than conventional acids or botanical extracts alone. The powder format gives R&D teams control over stock concentration, pH, preservative system, peptide recovery, and final texture.

Usage: Brightening serums, tone-evening gels, creams, lotions, masks, post-blemish spot 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.
