Tetrapeptide-21 (Powder) is a powder form of Tetrapeptide-21 for extracellular-matrix support and wrinkle-care formulas.

Tetrapeptide-21 is positioned to support ECM synthesis and reduce ECM degradation, which is relevant to wrinkle and firmness formulas.

This SKU is the powder form intended for formulators who want the same benefit direction as Tetrapeptide-21 solution, but prefer to prepare their own stock solution or premix and control the carrier system.

Product Description: This powder form is for preparing a controlled premix when you want the same ECM-focused benefit direction as the Tetrapeptide-21 liquid solution.

Usage: Anti-wrinkle serums, firming gels, neck creams, face creams, and leave-on ECM-support products.

Mixing method:

- Pre-dissolve or pre-disperse into a small compatible water/glycol phase before adding to the main batch.

- Add during cool-down, preferably below 40°C, and avoid prolonged heat exposure.

- Check final pH, clarity, odor, color, and active stability before scale-up.

Usage rate: typically 0.001-0.01% active powder; prepare a stock solution and dose to match the 2000ppm solution target where needed.

Because this is a concentrated powder, calculate dosage by delivered peptide level and validate performance, stability, and irritation in the finished formula.

Product characteristics: white powder.

Solubility: Pre-dissolve in water/glycol phase; add during cool-down and avoid heat.

Storage: Keep tightly closed, dry, protected from light and heat. Refrigerated storage is preferred for long-term peptide stability.
