Myristoyl Pentapeptide-17 Powder

The lash peptide in dry form

Myristoyl Pentapeptide-17 is the peptide most closely tied to lash and brow serums. Supplier copy positions it for the look of longer, denser lashes, and brands often build a small product line around it. The INCI is Myristoyl Pentapeptide-17 and the CAS is 959610-30-1. The myristoyl chain makes it a lipopeptide. This listing is the powder.

Powder and solution

Myristoyl Pentapeptide-17 solution is SKU VV24011801 on our peptide solutions list. Keep each card's CoA separate. Lash products often pair it with Biotinoyl Tripeptide-1.

Working with the powder

Dissolving

Weigh the powder on a calibrated balance, dissolve it completely in a small portion of the formula water before it meets the rest of the batch, and add that premix in cool-down, below 40 °C. Check that the premix is fully clear before you add it.

Compatibility

Existing notes for this SKU say to keep it away from strong oxidizers and high-ionic-strength systems, such as products very rich in salts. A mild, water-rich base is the safest home.

Level

This card does not state a use percentage, so follow the CoA and the supplier documentation for the level.

Solvent

Follow any CoA note on solvent for the myristoyl grade.

Product types that suit it

Lash serums, brow gels, lash conditioners, mascara primers and brow tints.

Pairing ideas

Panthenol, sodium hyaluronate, biotinoyl peptides and a light film former. Add each active separately and check clarity, odor and viscosity after each addition instead of premixing several actives in one beaker.

Example architecture

Water, glycerin, panthenol, a light polymer, the peptide premix at the supplier level, a chelator and a mild preservative, filled into a brush tube. The level comes from the CoA, so no gram recipe is shown here.

Claims

Describe lashes and brows that look longer, fuller and more defined with regular use. Keep claims cosmetic and tied to appearance. Any before-and-after statement needs a test on the finished product, not on the raw material.

Testing the finished product

Run a stability check on the finished product at room temperature, at 40 °C and in a fridge for several weeks, and watch color, odor, clarity, viscosity and pH. Check the product in its final pack too, since pumps, droppers and jars expose it to air differently. A preservative challenge test on the final product is the standard step before launch.

Lot handling and storage

Record appearance and pH on arrival, compare them with the CoA, and keep the CoA with your batch records so each finished batch can be traced to its lot. Keep the powder tightly closed and dry, since peptides pick up moisture from the air, and respect the shelf life on the CoA.

Labeling and documents

Write the INCI exactly as the CoA for your lot gives it, in the order the supplier lists it, and keep the CAS line the same as the CoA, including N/A or Mixture where that is what it says. Keep the CoA with your batch records. If your market needs an SDS or a full ingredient breakdown, ask for it before you scale so the paperwork matches the batch you buy.

Ordering

It is sold as a raw material for cosmetic formulation, not as a finished consumer product. Start with a small pack for bench trials and scale once your stability checks pass. It ships from Florida, usually within 1 to 2 business days, in the pack sizes shown above, and US shipping is free on orders of $50 or more.
