EDP, EDT or Extrait for Private Label? How Buyers Should Specify Concentration

When contacting a private label EDP manufacturer in China, buyers should specify both the desired market position and measurable product requirements. Otherwise, two suppliers can quote products called “eau de parfum” that differ in formula, fragrance load, raw-material quality, testing scope and sensory performance.

Quick answer

Use EDP, EDT or extrait as a starting description, then ask the supplier to confirm in writing:

• the exact fragrance-compound dosage for the quoted formula;
• whether the percentage is calculated by weight or volume;
• the complete base system, including alcohol and other functional ingredients;
• the approved fragrance formula or reference sample;
• stability and packaging-compatibility testing;
• the intended markets and required label review; and
• how a concentration change affects cost, clarity, color, spray behavior and performance.

Do not select a concentration from a generic internet chart and assume it guarantees longevity. Formula architecture, materials, skin, climate and application all affect how a perfume performs.

What EDP, EDT and extrait communicate—and what they do not

The familiar terms include eau de cologne, eau de toilette, eau de parfum, parfum and extrait de parfum. In commercial conversation, they generally suggest a progression in fragrance concentration or product positioning. However, percentage ranges quoted online are not a universal manufacturing specification.

The terminology alone does not tell a buyer:

• the precise fragrance dosage;
• which aroma materials are used;
• the quality or cost of the fragrance compound;
• how volatile and substantive the formula is;
• whether the liquid remains clear and stable;
• the amount of alcohol, water or other solvent;

• the applicable safety limits for the intended product use; or

• whether the proposed product name and label comply in the destination market.

For sourcing purposes, “I need a long-lasting EDP” is an incomplete brief. A better request combines a category, a defined benchmark and technical acceptance criteria.

Concentration is not the same as performance

A higher fragrance-compound percentage can change strength and diffusion, but it does not automatically produce better projection or longer wear.

Performance also depends on:

• the volatility of the chosen materials;
• the balance of top, middle and base notes;
• fixative and substantive materials within the fragrance design;
• the solvent and base system;
• skin type and application amount;
• temperature and humidity;

• bottle and pump output; and

• how performance is evaluated.

An airy citrus composition at a higher dosage may still feel shorter-lived than a lower-dosage amber or woody formula. Increasing concentration can also make a fragrance feel denser, reduce lift or change the balance intended by the perfumer.

The correct question is therefore not, “Which label lasts longest?” It is, “Which approved formula and dosage meet the sensory, technical and commercial target?”

A specification framework for private-label buyers

Use the following fields in the development brief.

The formula identification and dosage should be recorded on every evaluation sample. Feedback such as “Sample B is better” becomes unreliable if the exact version is not traceable.

How to discuss fragrance-compound percentage

Ask the manufacturer or fragrance supplier to state the dosage explicitly and consistently. Avoid ambiguous phrases such as “high concentration” or “premium oil.”

Clarify:

1. Is the stated percentage measured by weight or by volume?
2. Does “fragrance oil” mean the compounded fragrance mixture or a broader base?
3. Is the same compound being evaluated at several dosages?
4. Has the formula been reviewed for its intended product category and market?
5. Does the quotation include the same compound and dosage as the approved sample?

The approved sample, formula code, dosage and production specification should be linked. If the dosage changes after approval, treat it as a controlled revision—not as a silent cost adjustment.

Why simply adding more fragrance can create problems

More fragrance compound changes the physical system as well as the smell. Depending on the formula and packaging, a higher dosage may contribute to:

• cloudiness or sediment;
• color change;
• interaction with coatings, gaskets or plastics;
• staining risk on fabric;
• altered atomization;
• stronger initial impact but less desirable balance;

• higher raw-material cost; or

• a different safety or compliance assessment.

These outcomes are formula-specific. They cannot be predicted from the EDP or extrait name alone. The final concentration must be assessed with the actual fragrance compound, base and package.

See Perfume Stability and Packaging Compatibility Testing for the approval questions to document.

The sample ladder: compare one variable at a time

When concentration is a key decision, request a controlled set of samples. There are two useful approaches.

Same formula, different dosages

This helps the team hear how dosage changes intensity, diffusion, balance, color and drydown. All other variables should remain constant where technically possible.

Different formulas at a similar dosage

This helps isolate fragrance-design differences from concentration differences. It is useful when comparing several olfactive directions.

Avoid changing the formula, dosage and base simultaneously without clear labeling. If everything changes, the buyer cannot identify why one sample performs differently.

For structured feedback, use the process in How to Give Useful Perfume Sample Revision Feedback.

Define how performance will be evaluated

“Long-lasting” is subjective unless the team agrees on the test.

At minimum, record:

• sample code and dosage;
• number of sprays or applied amount;
• testing on blotter, skin or both;
• evaluation intervals;
• room or climate conditions where relevant;

• perceived projection and character over time; and

• evaluator observations.

Skin testing is important for consumer experience, but it varies among people. Blotter testing provides a more repeatable comparison, although it does not reproduce skin. Using both gives a more useful development record.

Do not turn a sensory panel into a false laboratory claim. The purpose is to make comparisons traceable and reduce approval based on memory alone.

Concentration and quotation comparison

When two manufacturers quote an EDP, confirm that the offers contain equivalent scope.

Compare:

• formula or fragrance-compound code;
• exact dosage;
• sample version;
• bottle fill volume and allowed tolerance;
• base composition approach;
• maturation, filtration and filling scope;
• testing included;
• documentation included;

• packaging specification; and

• treatment of reformulation or material substitution.

A lower price may reflect a different dosage, different fragrance compound or narrower testing scope. Requesting a line-item quotation makes those differences visible.

Safety and market compliance are formula-specific

Fragrance-use limits depend on the formula, intended use and applicable requirements. A general statement that a fragrance is “IFRA certified” is not enough to define the finished product.

The International Fragrance Association explains that a Certificate of Conformity to the IFRA Standards is prepared by the company supplying a fragrance mixture for an intended use. IFRA itself does not issue the certificate. The certificate also does not replace a complete safety assessment or compliance with local law.

Ask for documentation linked to the exact fragrance formula and intended product category. Then have the finished product and label reviewed for each destination market by the appropriate responsible party or qualified professional.

Questions to send the manufacturer

• What exact fragrance-compound dosage is included in this quotation?
• Is the dosage calculated by weight or volume?
• Which sample code and formula code correspond to the quote?
• Can we compare the same formula at controlled dosage levels?
• What base and filtration process are proposed?
• What changes in color or clarity are expected over time?
• What stability and packaging tests are included?
• Which documents are available for the exact formula?
• Does increasing the dosage require reformulation or renewed review?
• How will formula and dosage be controlled in mass production?
• What change-control process applies to raw-material substitutions?
• Which label and market claims remain for buyer-side regulatory review?

Common mistakes

Using a generic percentage chart as the purchase specification

Online ranges can be educational, but they do not identify the actual formula or legal position of the finished product.

Assuming “premium oil” defines quality

The phrase is not a measurable specification. Request the formula code, dosage, sample and agreed performance target.

Comparing different formulas only by percentage

Two formulas at the same dosage can have very different cost and performance. Evaluate the full composition and sensory result.

Approving scent on a blotter but ignoring the package

The final liquid must be tested with the selected bottle, pump, gasket, coating and storage conditions.

Letting the quotation drift away from the approved sample

Link purchase specifications to the exact approved formula and dosage, and require approval for changes.

Frequently asked questions

Is EDP always stronger than EDT?

It generally communicates a higher-concentration positioning, but the terms alone do not guarantee greater projection or wear. Exact dosage and formula design must be compared.

What fragrance percentage should I request for an EDP?

There is no single percentage suitable for every formula or market. Ask the development team to propose and document a dosage that meets the intended performance, safety, stability, cost and labeling requirements.

Can a manufacturer increase the concentration after sample approval?

Technically it may be possible, but it creates a new version that should be evaluated and documented. It can affect odor balance, clarity, compatibility, cost and compliance.

Does a higher concentration always cost more?

Using more fragrance compound often affects cost, but compound cost varies greatly by formula. Packaging, labor, testing and order size also influence the finished price.

Should I request an IFRA certificate for the finished perfume?

Ask for documentation appropriate to the exact fragrance mixture and intended use, but understand its scope. IFRA does not itself issue certificates, and a conformity certificate does not replace finished-product safety assessment or local legal compliance.

Final takeaway

EDP, EDT and extrait are useful commercial terms, not complete manufacturing specifications. The reliable sourcing unit is the approved formula code plus exact dosage, base, performance target, test plan, package and destination-market requirements.

When every sample and quotation carries those details, buyers can compare like with like and protect the approved result through mass production.
