INCI name
An INCI name is a standardized ingredient name used in cosmetic ingredient labeling under the International Nomenclature of Cosmetic Ingredients system. For example, Copper Tripeptide-1 is an INCI name used for a cosmetic ingredient. The name supports labeling and communication, but it is not a complete purchasing specification or proof of regulatory acceptance.
Why does INCI name matter when sourcing?
The INCI name helps align a raw-material inquiry with the ingredient declaration planned for a finished cosmetic formula. It reduces ambiguity when trade names differ, but buyers still need to reconcile the actual chemical identity, salt form, composition and supplier documentation. Labeling obligations also depend on the product and destination market.
What should you verify about INCI name?
Match the INCI name with the chemical name, CAS reference where applicable, sequence or structure, salt form and composition of the supplied material. If the ingredient is a solution or blend, establish the concentrations and other components. Confirm current labeling and market requirements with the responsible regulatory reviewer and authoritative sources.
What can INCI name not tell you?
An INCI name does not certify purity, net content, manufacturing quality, safety, efficacy or permission to market a finished product. Similar trade names and different material forms can create confusion, and an INCI match alone does not demonstrate that two suppliers offer equivalent specifications.
