This guide helps compare concentrations for a brand brief. If you are selecting a manufacturing service, explore EDP and extrait perfume manufacturing. Use sample evaluation to compare the actual result rather than choosing by percentage alone.
Define what the percentage refers to
When a perfume brief says 20%, 25% or 30%, record what the percentage refers to and how the formulation is measured. Fravanta can discuss these concentration directions for perfume projects, with the actual formula, carrier and specification agreed for the project. A product name such as eau de parfum or extrait is not a substitute for that specification.
Ask the supplier to identify the concentration alongside the sample version and carrier. This makes later comparisons meaningful and reduces ambiguity when a brief, sample label and quote use different shorthand. The percentage alone does not define the complete scent, its quality or a fixed number of wear hours.
Consider the carrier and use
| Product direction | What to include in the comparison |
|---|---|
| Alcohol-based perfume | Scent, alcohol-based carrier, concentration, dispensing and intended use |
| Alcohol-free perfume | Exact base requirement, application, feel and packaging suitability |
| Oil-based finished perfume | Oil carrier, application amount, feel and container or applicator |
The same percentage in different carriers does not establish identical performance or use experience. Compare each product in its intended format. An oil-based finished perfume is also a different request from raw fragrance concentrate for further formulation, so make that supply requirement explicit.
Connect concentration to the quotation
Concentration is one quotation input alongside scent composition, carrier, quantity, performance target, development work, packaging and delivery scope. Changing a percentage can change the formula being discussed, but it does not justify a universal cost multiplier or an assumption that one product offers better value.
For a useful comparison, request the same scent and carrier direction at the concentrations you genuinely want to evaluate. Ask which development and sample work is included, and keep the finished liquid, pack, filling and delivery items visible. The cost guide provides a structure for comparing the scope.
Compare samples under consistent conditions
Identify each sample by scent, version, carrier and stated concentration. Use the supplier’s agreed product instructions and the same reference and evaluation setting. Record your chosen observation times and conditions, along with what you notice at each point; the observations should support your target rather than chase a promised number of hours.
Separate the fragrance character from the intensity. A sample may be stronger than the reference yet have a sweeter opening that is less suitable for the brand. Use the evaluation record to list the characteristics to retain, changes needed and their priority. Sample evaluation is also separate from the packaging compatibility and other checking scope agreed for production.
Write a performance direction, not just a number
A practical brief combines audience, occasion, market, scent, carrier, desired presence and budget. For example: “An alcohol-based perfume with a clear woody identity for everyday use; compare the agreed concentration options against our reference, keeping the dry finish and avoiding a sweeter opening.” This is a development direction, not a finished specification or performance claim.
Add the intended fill, dispensing format, number of scents and quantity so that the sample and quote address the same product. Discuss sample options or review the sample process when you are ready to choose between formula directions. The accepted sample and written specification should settle the final concentration choice together.
