“Concentration” can refer to two related ideas: the dosage of fragrance concentrate in a finished formula, and the marketing classification of perfume products (such as eau de parfum versus eau de toilette).
For B2B development, the practical question is usually dosage: how much fragrance oil or concentrate will be used in the finished product, and whether that dosage is compatible with the base, process, and cost target.
Higher dosage does not automatically mean a better product. Stability, clarity, skin feel, burn performance (for candles), and regulatory limits can all constrain how much fragrance a formula can carry.
During sampling, ask suppliers to recommend a starting dosage for your application and to note whether the material is intended for alcoholic fine fragrance, emulsion systems, surfactants, or wax. Matching dosage guidance to application avoids misleading evaluations.
When moving from sample approval to commercial supply, confirm that the quoted material, dosage assumptions, and packaging units align with your production plan. Misaligned assumptions are a common source of quotation rework.
