Use the exact INCI name Acetyl Dipeptide-1 Cetyl Ester in your brief. Distinguish the peptide ingredient from a prepared multi-ingredient blend. For a liquid supply option, ask for the complete INCI composition, carrier ingredients, preservation system and the basis used to report active content.
Carrier and formulation fit
Share your skin-care or hair-care formulation format, solvent system and intended use area. Ask the supplier for compatibility information relevant to your emulsion or aqueous system, then define your own stability and finished-formula evaluation.
Identity and assay questions
Specify the identity test and assay method required by your team. Clarify whether a result describes the peptide component or the complete blend, how active content is calculated and which carrier ingredients must be declared.
Trial material and documents
Describe the trial purpose and sample quantity. Request a current specification, relevant batch COA, SDS and technical information from the selected supplier; confirm document scope and sample availability before procurement.
