Eyeseryl Solution B

A small pack for lab trials

This listing is Eyeseryl Solution B in a 2 ml pack, the small-format version of the Acetyl Tetrapeptide-5 eye-contour solution, CAS 820959-17-9. A 2 ml pack is designed for bench work: checking how the peptide behaves in your eye-gel base, running a short stability check, and making a first sample for a client before committing to a larger size.

Same chemistry as the larger packs

The active and its documentation match the other Eyeseryl Solution B listings: the main Eyeseryl Solution B page and the 50 ml pack. Confirm the full vehicle INCI on the CoA for each lot. When you move from the 2 ml pack to a larger size, keep the same lot documentation in your file and check that the CoA matches.

Planning lab batches with 2 ml

Two milliliters goes further than it sounds in a lab. Most cosmetic peptide solutions are used at a few percent, so one pack is usually enough for several small trial batches of an eye gel. Use a calibrated micropipette or a precision balance and weigh rather than estimate volumes, because small errors matter at this scale. The use level is not stated on this card; follow the supplier documentation.

Formulating an eye gel

Base

A clear water-gel with a gentle polymer, a humectant such as glycerin and a mild preservative validated for the eye area is the classic base.

Adding the peptide

Add the solution during cool-down, below 40 °C, mixing gently. Record pH and clarity before and after addition.

Pairing ideas

Combine with Hyaluronic Acid Liquid for a cushioned feel and with Dipeptide-2 for a two-peptide under-eye concept. Add each active separately in cool-down.

Claims

Keep claims cosmetic: the look of puffiness, a smoother, fresher-looking eye contour. Avoid wording about circulation or fluid drainage.

Storage

Small packs are opened and closed often. Keep the vial tightly closed, refrigerate after opening where practical, use clean tools, and finish it within the shelf life on the CoA.

From sample pack to production

When the trial batches look good, the next step is a larger lot. Order a bigger pack of the same chemistry, compare its CoA with the 2 ml pack's documents, and run one confirmation batch before full production. Small differences in appearance or pH between lots are normal; record them so you can trace each finished batch back to its peptide lot.

Sharing samples with clients

Contract manufacturers and private-label teams often use small packs to build client samples. A 2 ml vial is enough for several sample batches of an eye gel, which keeps early-stage development costs low while the client decides on texture and packaging.

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 all peptide solutions.
