High-purity Myristoyl Pentapeptide-17 powder for fuller-looking, longer-looking, stronger-looking lash and brow serums. Freeze-dried powder form.
Myristoyl Pentapeptide-17 is a high-purity cosmetic peptide powder for lash and brow conditioning formulas that target fuller-looking, longer-looking, stronger-looking lash and brow appearance.
Physical form: This product is supplied as a freeze-dried powder.
This peptide is a strong fit for premium lash serums, brow serums, targeted leave-on gels, and conditioning treatments where a low-ppm peptide active can be delivered accurately. It is commonly used in lash-conditioning concepts and pairs well with complementary lash peptides such as Myristoyl Hexapeptide-16.
Product Description: Use Myristoyl Pentapeptide-17 when the formula needs a clean peptide story for stronger-looking lashes and brows without using drug-style lash-growth claims. The powder format is ideal for professional R&D teams that want precise control over stock solution concentration, pH, preservative system, and final peptide recovery.
| Formula target | Recommended positioning |
|---|---|
| Lash conditioning | Fuller-looking, longer-looking, stronger-looking lash appearance with routine use. |
| Brow care | Brow serums and conditioners for brows that look denser, better groomed, and healthier. |
| Premium peptide blend | Works well in multi-peptide lash/brow systems with Myristoyl Hexapeptide-16 and compatible humectants. |
Usage: Lash serums, brow serums, lash conditioners, brow conditioners, lightweight gels, and targeted leave-on products for lash/brow appearance care.
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.
- For eye-area use, confirm clarity, preservative compatibility, peptide recovery, and irritation profile in the finished 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.
