Oligopeptide 8

What Oligopeptide-8 is

Oligopeptide-8 is an INCI name for a short synthetic peptide chain. This listing supplies it as a water-compatible solution for leave-on skin care. During our catalog review the CAS for Oligopeptide-8 was not verified in open registries, so the page shows CAS as N/A. The INCI is Oligopeptide-8, with the full vehicle confirmed on the CoA for each lot.

How it differs from other oligopeptides

"Oligopeptide" plus a number is a family of INCI names, and each number is a different material. Oligopeptide-1 and Oligopeptide-2 are separate listings, often tied to biotech-style trade names, and they are not interchangeable with Oligopeptide-8. Choose by the INCI on your formula sheet and confirm it on the CoA.

Formulating with Oligopeptide-8

Process

Add the solution to the water phase during cool-down, below 40 °C, and mix gently. Avoid prolonged high heat after addition and avoid strong shear.

Base

Serums, essences and light gel-creams suit a water-compatible peptide. Record pH, clarity and viscosity in your base before and after addition, and keep the finished pH within the range of your preservative.

Use level

Take the use level from the supplier documentation for your lot. Follow the supplier documentation and run a small pilot first.

Claims and positioning

Without supplier data tied to a specific claim, keep wording general: skin that looks smoother and feels conditioned. If your supplier provides test data for this lot, align claims with that data only.

Formula ideas

A minimal essence can combine water, glycerin, a light humectant such as Hyaluronic Acid Liquid, Oligopeptide-8 and a preservative. In a multi-peptide serum, add each peptide separately in cool-down and check compatibility.

Quality and storage

Run stability at room temperature and 40 °C in the final packaging. Keep the raw material tightly closed, cool and away from light, and refrigerate opened material where practical. Keep the CoA with your batch records.

Building a multi-peptide essence

Oligopeptides are often used in light essences and ampoules, where a few actives at modest levels sit in a thin, fast-absorbing base. Oligopeptide-8 can share that base with humectants, a soothing ingredient such as panthenol and a second peptide chosen for a specific claim. Add each peptide separately in cool-down so you can track how each one affects clarity and pH.

Qualifying the lot

On arrival, compare appearance and pH with the CoA. Run a compatibility check in your base and a stability study in the final packaging before you scale. If the CoA lists an INCI other than Oligopeptide-8, use the CoA name on your label.

Packaging

Airless pumps and dropper bottles with small openings limit air contact and contamination. For ampoules, single-use formats avoid the need for a strong preservative system, but still validate microbiological quality.

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 $50 or more. Compare other oligopeptides in our peptide solutions section.
