Octapeptide 2 Powder

An eight-amino-acid peptide with limited public data

Octapeptide-2 is a synthetic peptide of eight amino acids, used in leave-on skin and scalp products. Its public documentation is thin, so this page sticks to what we can confirm. This page is the powder. The US catalog INCI is Octapeptide-2. CAS is N/A, because no number has been verified for this grade. Appearance and any supplier positioning should be checked on the CoA and documents for your lot.

Not Acetyl Octapeptide-3 Solution

The names are close, but Acetyl Octapeptide-3 Solution is Acetyl Octapeptide-3, a different eight-amino-acid sequence on the solution list with an expression-line story. Octapeptide-2 is not a substitute for it. There is no Octapeptide-2 solution on our solution list, so the powder is the only form we carry. Other dry peptides are 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

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

Take the use level from the supplier documentation for your lot.

Product types that suit it

Leave-on serums, scalp tonics, essences and light gel creams. Start with a simple base so any stability change is easy to trace.

Pairing ideas

D-Panthenol, sodium hyaluronate, glycerin and a gentle preservative system. Add each active separately and check clarity, odor and viscosity after each addition instead of premixing several actives in one beaker.

Example architecture

The level comes from the CoA, so no gram recipe is shown here.

Claims

Keep claims general and cosmetic, such as skin that looks smoother or hair that looks fuller, and back them with a test on the finished product. 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.

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 $35 or more.
