Acetyl Tetrapeptide-5 (Powder) is a powder form of Acetyl Tetrapeptide-5 for eye-area formulas targeting puffiness and dark-circle appearance.

The matched solution form is used for glycation-inhibition and vascular-permeability concepts, both relevant to under-eye bags and dark circles.

This SKU is the powder form intended for formulators who want the same benefit direction as Pep®-Eye (Acetyl Tetrapeptide-5), but prefer to prepare their own stock solution or premix and control the carrier system.

Product Description: This powder lets formulators build their own preservative and humectant system while keeping the same Acetyl Tetrapeptide-5 benefit direction as Pep®-Eye.

Usage: Eye serums, eye gels, under-eye creams, and lightweight leave-on 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 0.001-0.05% active powder, or dose through a stock solution to match the target delivered Acetyl Tetrapeptide-5 level.

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 to off-white peptide powder.

Solubility: Pre-dissolve in water/glycol phase; avoid high electrolyte or harsh preservative systems until compatibility is confirmed.

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