Myristoyl Pentapeptide-17 Solution (Lash Peptide)

Myristoyl Pentapeptide-17 is the INCI name of the lipopeptide often simply called the lash peptide.

The INCI-named lash peptide

This listing is the INCI-named solution of Myristoyl Pentapeptide-17, CAS 959610-30-1. A myristoyl fatty-acid chain is attached to a five-amino-acid peptide, which makes it a lipopeptide well suited to lash and brow conditioners. The full vehicle INCI is confirmed on the CoA for each lot.

Choosing among the Myristoyl Pentapeptide-17 listings

The same peptide is sold as XLash Peptide, as Eye Lash Penta Peptide, and as a powder. Buying by INCI keeps purchasing documents, label and formula sheet aligned under one name. Solutions and the powder differ in active content, so recalculate whenever you switch.

Formulating a lash conditioner

Base

A lash serum needs a thin, quick-drying base that will not run into the eye. A clear water-gel with a little glycerin, a thin polymer and a preservative validated for eye products is typical.

Process

Add the solution in cool-down, below 40 °C, and mix gently. Record clarity, viscosity and pH. Take the use level from the supplier documentation for your lot.

Brow products

The same peptide works in brow serums and tinted brow gels. In tinted gels, add the peptide after the pigment dispersion and check that the color stays even.

Pairing ideas

Myristoyl Pentapeptide-17 is often combined with Myristoyl Hexapeptide-16, Biotinoyl Tripeptide-1 and panthenol in multi-active lash serums. Add each active separately in cool-down.

Example: lash serum architecture

Water, glycerin, a thin gel former, Myristoyl Pentapeptide-17, a second lash peptide and panthenol, with an eye-safe preservative. Exact levels come from the supplier documentation. A fine liner-style brush in a slim tube allows precise application at the lash line.

Claims

Keep claims cosmetic: longer-looking, fuller-looking lashes and brows after regular use. Ophthalmologist-tested claims need the corresponding test on the finished product.

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. Store tightly closed, cool and away from light.

Applicator and safety notes

Lash products sit close to the eye, so the applicator matters. A fine brush that holds a small amount of serum limits the risk of product running into the eye. Instructions should tell people to apply to clean, dry lash lines once a day and to stop use if irritation occurs. Keep the formula fragrance-free and plan eye-area tolerance testing on the finished product before launch.
