Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid, IO

Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid is the trade name for a solution of two INCI peptides, Palmitoyl Tripeptide-1 (also written Pal-GHK) and Palmitoyl Tetrapeptide-7 (Pal-GQPR). Buyers who want one of the pair alone can order Palmitoyl Tripeptide-1, and the single-matrikine option is Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid KTTKS.

What is Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid?

Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid is a ready-to-use commercial solution that combines two matrikine peptides, Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7, for serums and creams aimed at firmer, smoother-looking skin. The published commercial INCI is Glycerin (and) Water (Aqua) (and) Butylene Glycol (and) Carbomer (and) Polysorbate 20 (and) Palmitoyl Tripeptide-1 (and) Palmitoyl Tetrapeptide-7. CAS is listed as Mixture, with Palmitoyl Tripeptide-1 at 147732-56-7 and Palmitoyl Tetrapeptide-7 at 221227-05-0. Confirm the full INCI on the CoA for each lot.

Why formulators choose it

The two peptides are palmitoylated, which makes them more compatible with skin lipids, and the supplier vehicle already contains glycerin, a carbomer and a solubilizer. That means the peptides arrive pre-dispersed: you add one liquid instead of handling two fine powders. It is the classic choice for a firming serum, a night cream or an eye cream where the claim language focuses on the look of firmness, texture and fine lines.

How to use the solution

Order of addition

Add Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid to the water phase during cool-down, below 40 °C, after the base viscosity is built. Mix gently; avoid prolonged high heat and aggressive shear after addition. The solution is slightly viscous because of its carbomer, so allow a few minutes of slow stirring for it to disperse evenly.

Compatibility notes

Because the vehicle contains a carbomer and polysorbate, check the final viscosity and clarity in your own base, especially in clear gels with high electrolyte loads. Use level is not stated on this card; follow the supplier documentation for the lot you receive.

Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid versus expression-line peptides

Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid belongs to the matrikine family and is positioned for firmness and texture. Expression-line peptides such as Acetyl Hexapeptide-8 Amplified Solution and Acetyl Octapeptide-3 Solution have a different claim architecture. Many serums combine one of each family, added separately in cool-down. Formulators who want a single matrikine can also look at Palmitoyl Pentapeptide-4.

Finished product ideas

Common homes include firming face serums with hyaluronic acid, night creams with a light emulsion base, eye creams, and neck and décolleté creams. Pair the peptides with humectants such as glycerin and a hydrating layer built on Hyaluronic Acid Liquid for a plump, comfortable feel.

Quality checks before scale-up

Before scaling, run a small pilot and record pH, viscosity and appearance before and after the peptide addition. Because the solution brings its own carbomer, a gel may thicken slightly, while a high-salt formula may thin out. Test in the final packaging at room temperature and at 40 °C for several weeks, checking odor and color at each time point.

Storage

Keep the solution tightly closed in a cool place away from light, refrigerate opened material where practical, and respect the shelf life shown on the CoA. Do not freeze unless the supplier documentation allows it.

Buying and shipping
