Pentapeptide-18 is a high-purity cosmetic peptide powder for anti-aging formulas that target the appearance of expression lines. It is especially suitable for serums, eye-area products, gels, and creams designed to make dynamic wrinkles look smoother and more relaxed.

This peptide is commonly selected for expression-line concepts because it is used as an enkephalin-like cosmetic peptide in leave-on skin care. It gives formulators a precise, modern active for forehead lines, crow's feet, and other facial-expression areas where customers want a smoother-looking finish without a heavy texture.

Product Description: Pentapeptide-18 is supplied as a concentrated peptide powder for professional cosmetic formulation. It is ideal for premium anti-wrinkle serums, eye gels, targeted line-smoothing products, masks, and lightweight creams.

Usage: Use in leave-on products for expression-line smoothing, forehead lines, eye-area lines, and dynamic wrinkle appearance. It can be used in serum, gel, lotion, cream, mask, and targeted treatment-style cosmetic formulas.

Mixing method:

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

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

- Recommended finished-product pH: 5.0-7.0.

- For eye-area or sensitive-skin products, confirm irritation profile and peptide recovery in the finished formula.

Usage rate: 0.001-0.01% of pure peptide powder. For first prototypes, start at a low level and adjust according to performance target, stability, and claim support.

Product characteristics: White to off-white powder.

Solubility: Best prepared as a water/glycol stock solution before blending into the formula.

Storage: Store tightly closed, protected from moisture. Keep refrigerated at 2-8°C for long-term storage.
