Tripeptide-41 Powder

A tripeptide for the body-care shelf

Most peptides on our list end up in face serums. Tripeptide-41 is one of the few aimed at the body. Existing supplier literature, in the Liporexin and CG-Lipoxin class, positions it for body-contour leave-ons such as firming creams and contour gels. This page is the powder. The published INCI is Tripeptide-41 and the CAS is 1093241-16-7. Appearance is confirmed on the CoA for each lot.

Other body-contour peptides

Silusyne is Acetyl Hexapeptide-39 and Ucpeptide V is Pentapeptide-25. Both have a body-contour story, but they are different sequences, and some brands combine two of them in one product. There is no Tripeptide-41 solution on our solution list, so the powder is the only form we sell. The dry range is 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

Body-contour creams, firming body gels, thigh and arm serums, and massage gels with a smoothing story. Fast-absorbing gels suit body products that people apply daily.

Pairing ideas

Caffeine, other body-contour peptides, glycerin and light plant oils. Caffeine is a classic partner in contour gels. 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

Describe skin that looks smoother, firmer and more toned with regular use. Avoid claims about fat loss or body weight. 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.
