RIGIN

Half of Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid, on its own

RIGIN is a cosmetic solution of Palmitoyl Tetrapeptide-7, CAS 221227-05-0. If the name sounds familiar, it is because this peptide is one of the two actives in Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid, where it is paired with Palmitoyl Tripeptide-1. Selling it alone lets formulators set its level independently, for example in a soothing-leaning firming cream or a custom multi-peptide blend.

INCI and documents

The INCI is Palmitoyl Tetrapeptide-7, with the full vehicle confirmed on the CoA for each lot. Take the use level from the supplier documentation for your lot.

Why buy RIGIN alone

The ready Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid blend fixes the ratio of its two peptides. Buying the peptides separately, RIGIN plus Palmitoyl Tripeptide-1, lets you adjust each one, match an existing formula sheet, or build a different matrikine pair. It also suits briefs where only the tetrapeptide is wanted, such as comfort-positioned creams for skin that looks stressed.

Formulating with RIGIN

Process

Add the solution in the water phase during cool-down, below 40 °C. Palmitoylated peptides are more lipid-compatible than plain peptides, so the solution may look slightly hazy; mix until uniform.

Bases

Firming serums, day and night creams, eye creams and neck creams are typical. In emulsions, add after the emulsion has formed and cooled.

Pairing ideas

Pair with Palmitoyl Tripeptide-1 to rebuild the classic matrikine duo, or with an expression-line peptide in a broader age-care serum. Hydrators such as glycerin and hyaluronic acid help the finish. Add each peptide separately in cool-down.

Claims

Keep claims cosmetic: firmer-looking skin, smoother texture, a calmer, more even look.

Quality and storage

Record pH and appearance before and after addition, and run stability at room temperature and 40 °C in the final packaging. Store tightly closed, cool and away from light.

Rebuilding the matrikine pair yourself

Some brands prefer to buy Palmitoyl Tetrapeptide-7 and Palmitoyl Tripeptide-1 separately rather than as a blend. It lets them list both peptides on the label, set each level from the supplier documentation and adjust the balance between products in a range, for example more tetrapeptide in a comfort-positioned night cream and a balanced pair in a day serum.

Practical notes for palmitoyl peptides

The palmitoyl chain makes these peptides partly lipophilic. In clear water gels they may give a slight haze; a small amount of a solubilizer or glycol often helps. In emulsions they disperse easily once the emulsion has cooled. Always add them after heating steps are finished.

Documents

The CoA confirms identity and the vehicle for each lot. Keep it with your batch records, and record pH and appearance on arrival so you can compare lots over time.
