Eyeseryl Solution B

The production-size Eyeseryl pack

This listing is Eyeseryl Solution B in a 50 ml pack, the Acetyl Tetrapeptide-5 eye-contour solution, CAS 820959-17-9. It shares its chemistry with the 2 ml sample pack and the main Eyeseryl Solution B listing; this card is the 50 ml size for pilot and small production batches. Confirm the full vehicle INCI on the CoA.

Moving from trials to production

A typical path is to test in a small pack, confirm the base and stability, then move to a 50 ml pack for pilot batches and first production runs. When you change pack size, compare the new CoA with the documents from your trials and run a confirmation batch.

Planning batch quantities

Calculate how much solution each batch needs from the supplier's use level, then plan how many batches one pack will cover. Weigh rather than measure by volume, and keep a log of pack opening dates so material is used within its shelf life.

Formulating an eye gel

Base

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

Process

Add the solution during cool-down, below 40 °C, mixing gently. Record clarity, viscosity and pH. This card does not state a use percentage; follow the supplier documentation.

Pairing ideas

Pair with Dipeptide-2 Eyeliss-lik for a two-peptide puffiness concept and with hyaluronic acid for a cushioned feel. Add each active separately in cool-down.

Example: under-eye gel architecture

Water, glycerin, a gentle gel former, Eyeseryl Solution B, Dipeptide-2 and hyaluronic acid, with an eye-safe preservative. Exact levels come from the supplier documentation.

Claims

Keep claims cosmetic: the look of under-eye puffiness, a smoother, fresher-looking eye contour.

Storage

Keep the pack tightly closed, refrigerate after opening where practical, use clean tools, and finish it within the shelf life on the CoA.

Stock rotation for opened packs

A 50 ml pack may be opened several times across production runs. Label each pack with its opening date, keep it refrigerated where practical, and use the oldest open pack first. Use clean, dry tools each time to avoid contamination. If appearance or odor changes, compare with the CoA before using it in a batch.

Documents

Keep the CoA of each pack with the batch records of every batch it supplied.

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.
