Biopeptide CL

A lipid-linked GHK matrikine in liquid form

Biopeptide CL carries Palmitoyl Tripeptide-1, the GHK tripeptide with a palmitic acid chain attached. The fatty-acid tail makes the short peptide more compatible with the lipid-rich surface of skin, which is why palmitoyl peptides became the classic "matrikine" family in collagen-story skin care. The ingredient on this page is a ready solution, so there is no weighing of milligram amounts of dry peptide. CAS for the commercial grade is Mixture; the peptide itself is listed as 147732-56-7. The full vehicle INCI is confirmed on the CoA for each lot.

Where it sits in our peptide range

This listing is one of several palmitoyl options among our peptide solutions. Biopeptide EL is a different molecule, Palmitoyl Hexapeptide-12, built around an elastin-derived sequence. Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid pairs Palmitoyl Tripeptide-1 with Palmitoyl Tetrapeptide-7. Choose Biopeptide CL when you want the tripeptide alone and plan to build the rest of the system yourself.

Formulating with Biopeptide CL

Phase and temperature

Add it in cool-down, below 40 °C, with gentle mixing, and avoid long holds at high temperature. The solution blends into the water phase of gels, serums and emulsions. In emulsions, add it after the emulsion has formed and cooled, never into the hot oil phase.

Level and pH

Take the use level from the supplier documentation for your lot. Record the pH of the finished product and keep it in the range the supplier documentation names. Very acidic products, such as strong acid exfoliants, are a poor home for most peptides and should be checked for stability.

Product types that suit it

Firming-look face serums, eye gels, neck and décolleté creams and night creams are the usual homes for a palmitoyl matrikine. Lightweight water-gels show off the peptide without heavy texture, while richer creams suit drier skin types. It also fits into multi-peptide serums next to Acetyl Hexapeptide-8-class expression-line peptides.

Pairing ideas

Hyaluronic acid, glycerin and panthenol support a plumper, more hydrated look. Niacinamide and ceramides are common companions in barrier-minded creams. Add each active separately and check clarity and viscosity after each addition rather than premixing several actives in a beaker.

Example: firming-look serum architecture

Exact amounts come from the CoA and the supplier documentation, which is why no gram recipe is given here. An airless pump keeps the serum away from air and light.

Claims

Keep claims cosmetic: skin looks firmer, smoother and more elastic with regular use. Before-and-after claims need a test on the finished product, not on the raw material.

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. Store tightly closed, cool and away from light, and respect the shelf life on the CoA.

Ordering

Biopeptide CL is sold as a raw material for cosmetic formulation, not as a finished serum. Start with a small pack for lab trials and scale up once your stability tests 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.
