Hexapeptide-9 Powder

A structure peptide, not an expression-line one

Hexapeptide-9 is a six-amino-acid signal peptide. Existing copy links it to collagen and laminin and a firmer, smoother look, and calls it suitable for eye and neck products. The INCI is Hexapeptide-9 and the CAS is 885024-94-2. This listing is the powder, a fine powder per the stored record.

Next to Argireline

Argireline is described as an expression-line peptide, while Hexapeptide-9 is described for structure support. Existing copy says the two can sit in one product, as can copper peptides. No Hexapeptide-9 solution is on our list. Compare dry options in our peptide powders.

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.

Product types that suit it

Firming-look serums, eye creams, neck creams and night creams.

Pairing ideas

Acetyl Hexapeptide-8, copper peptides, sodium hyaluronate and glycerin. 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, sodium hyaluronate, the peptide premix at the supplier level, a chelator and a preservative. The level comes from the CoA, so no gram recipe is shown here.

Claims

Describe skin that looks firmer and smoother 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.
