Silusyne Powder

A hexapeptide for contour-look body care

Silusyne is the peptide brands use when they want a body cream or jawline gel to carry a contour story. Existing supplier positioning describes it for the look of smoother, more defined body contours. This page is the powder, a raw cosmetic ingredient and not a finished body cream. The published INCI is Acetyl Hexapeptide-39 and the CAS is 1382088-38-1. Appearance is confirmed on the CoA for each lot.

How it compares

Tripeptide-41 and Ucpeptide V, Pentapeptide-25, are other body-contour peptides. They are different sequences, so pick one by its own documentation or combine them with each at its own level. Silusyne also shares only part of its name with Acetyl Hexapeptide-8; they are unrelated in use. There is no Silusyne solution on our solution list. 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, jawline and neck serums, and post-shower body lotions.

Pairing ideas

Caffeine, glycerin, sodium hyaluronate and light plant oils. 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 and contours that look smoother, firmer and more defined. 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.
