1. Define the real product
Shampoo, conditioner and body wash may use different formulation systems. Define the base, audience and market; similar notes do not prove interchangeability.
2. Shortlist notes and cost
Use scent directions and a CNY/kg budget to narrow the library. Matching source notes is a discovery step, not a performance test.
3. Record the unknowns
Dosage, stability, colour change, regulatory restrictions, sampling fees and lead time need confirmation for the specific base and market. The source spreadsheet cannot establish them.
