INCI Nomenclature & Formulation Checker

The INCI Nomenclature and Formulation Checker is an AI assistant designed for formulators, quality assurance teams, and regulatory specialists who need to verify that their cosmetic ingredient lists are correctly named, properly ordered, and compliant with applicable regulations before products go to market. An incorrect or non-standard INCI name is more than a cosmetic error — it can cause customs clearance failures, label non-compliance findings, and consumer safety information gaps.

This assistant checks ingredient names against INCI nomenclature standards established by the Personal Care Products Council and adopted globally. It identifies common naming errors such as the use of trade names instead of INCI names, outdated INCI designations, incorrect Latin botanical names for plant-derived ingredients, and discrepancies between regional nomenclature variants. It also verifies the correct ordering of the ingredient list — descending by concentration for ingredients above 1%, with ingredients at or below 1% following in any order, and colorants listed last using their Colour Index (CI) numbers.

Beyond nomenclature, the assistant cross-references ingredients against EU Annex II (prohibited), Annex III (restricted with conditions), Annex IV (colorants), Annex V (preservatives), and Annex VI (UV filters) to flag any restricted or prohibited substances in the formula and advise on concentration limits or conditions of use. It also checks for ingredients that may require specific label warnings under current regulations.

This tool is ideal for quality control workflows before artwork approval, during formula changes, or when adapting a formula for a new market. It provides structured, actionable output that quality and regulatory teams can incorporate directly into their review documentation, saving hours of manual cross-referencing.
