Palmitoyl Tripeptide-1 Solution (Pal-GHK)

Palmitoyl Tripeptide-1 is also written Pal-GHK and was once listed as Palmitoyl Oligopeptide.

Pal-GHK on its own

Palmitoyl Tripeptide-1 is the palmitoylated form of the GHK tripeptide, often written Pal-GHK, CAS 147732-56-7. It is used in firming and smoothing leave-on products. This listing supplies it alone as a solution; the full vehicle INCI is confirmed on the CoA. It is a liquid suited to water-phase addition.

Where it fits in the catalog

Palmitoyl Tripeptide-1 is one of the two peptides in Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid, where it pairs with Palmitoyl Tetrapeptide-7. It is also sold as the trade solution Biopeptide CL. Buying the INCI-named listing lets you set its level independently, pair it with RIGIN to rebuild the matrikine duo, or combine it with a different partner.

Formulating with Palmitoyl Tripeptide-1

Process

Add the solution during cool-down, below 40 °C, and mix until uniform. The palmitoyl chain makes the peptide partly lipophilic, so a faint haze in clear gels is normal; a small amount of glycol or solubilizer can help.

Bases

Firming serums, night creams, eye creams and neck creams are typical. In emulsions, add after cooling. Take the use level from the supplier documentation for your lot.

Pal-GHK versus copper GHK

Palmitoyl Tripeptide-1 carries a fatty-acid chain and no copper. It is colorless and does not bring the chelation sensitivity of GHK-Cu. Choose it for clear firming serums; choose copper peptide for a blue copper story.

Example: matrikine pair serum architecture

Water, glycerin, a light gel former, Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 added separately, plus hyaluronic acid and a validated preservative. Exact levels come from the supplier documentation.

Claims

Keep claims cosmetic: firmer-looking, smoother skin and the look of fine lines.

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.

Lipopeptides in production

In production, add Palmitoyl Tripeptide-1 after cooling and after any homogenizer step. If you use a solubilizer for clarity, premix it with the peptide in a little batch water before adding it to the main tank. Rinse the weighing vessel with batch water so the full dose goes in. Measure clarity and pH on each production batch and compare them with your pilot.

Ordering

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. Compare all peptide solutions.
