The public overview identifies the catalogue material. Confirm the supplied grade, full composition and current batch specifications in the supplier documents.
Development directions
Facial-care formulation enquiry with the cetyl-ester identity and supplied form confirmed first.
Possible formulation formats
- Facial emulsion concept after dispersion review
- Serum concept with a supplier-defined carrier system
These are development concepts for discussion. Confirm identity and supplied-material guidance before formula evaluation.
Identity and supplied form
PubChem CID 11685829 records CAS 196604-48-5 as Acetyl Dipeptide-1 Cetyl Ester. The cetyl ester is part of this identity and should be checked on the quotation and ingredient declaration. The catalogue title is retained; request the current supplier declaration for the offered powder or solution.
Formulation review priorities
| Review point | What to establish |
|---|---|
| Identity and supplied concentration | Match the cetyl-ester name and CAS to the declaration; compare powder assay and solution peptide content on the same basis. |
| Formula and evaluation | Request dispersion and processing guidance for the supplied material, then define stability and finished-formula evaluation. |

Questions for your brief
- Does the quotation specify Acetyl Dipeptide-1 Cetyl Ester under CAS 196604-48-5?
- Is the offer a powder or a formulated solution, and how is peptide content expressed?
- What carrier, addition process and compatibility checks are advised for the proposed serum or emulsion?
Why does the reference name include Cetyl Ester?
PubChem links the listed CAS to the cetyl-ester derivative. Use that complete identity when checking the offered material; the shorter catalogue name alone is not enough to distinguish derivatives.
Can powder and solution offers use the same dosage?
Compare their actual peptide-content basis and carrier composition first. A percentage of a supplied solution is not automatically the same amount of peptide as the same percentage of powder.
