Caprooyl Tetrapeptide-3 Powder, IO

The dry form of a skin-structure peptide

Caprooyl Tetrapeptide-3 Powder is for formulators who want to set their own peptide concentration instead of buying a ready solution. It is a powder of Caprooyl Tetrapeptide-3, the same INCI that is also sold under the Caprooyl Tetrapeptide-3 Solution name, and it is used in leave-ons aimed at firmer, denser-feeling skin. The published CAS is 1012317-71-3. Appearance is confirmed on the CoA for each lot.

Powder or solution

Caprooyl Tetrapeptide-3 Solution is Caprooyl Tetrapeptide-3 in solution, SKU T60064. This page is the powder. Same INCI, different form, so pick the one that matches your process and switch only after a new stability check. Dermican is a different firming tetrapeptide and not a substitute. More 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

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 night serums, face and neck creams, jawline gels and mature-skin moisturizers.

Pairing ideas

Matrikine peptides such as Palmitoyl Pentapeptide-4, sodium hyaluronate, ceramides and squalane. 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, an emulsifier system, light emollients, a ceramide blend, a Caprooyl Tetrapeptide-3 Powder premix at the supplier level in cool-down, a chelator and a broad-spectrum preservative. The level comes from the CoA, so no gram recipe is shown here.

Claims

Describe skin that looks firmer, denser and more resilient 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.

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.
