Custom Fragrance Development, Benchmark Matching or Customer-Owned Formula Manufacturing: Which Model Fits Your Project?

Not every fragrance project starts from the same point.

Some customers have a product concept and a preferred scent direction but no fragrance formula. Others already have a fragrance sample they want to match. Some customers have completed their own R&D and own a mature fragrance formula—they simply need a reliable manufacturing partner to make samples and produce the formula consistently at scale.

These projects require very different approaches.

In B2B fragrance development, we generally see three common cooperation models:

Custom Fragrance Development – developing a new fragrance according to the customer’s brief.

Benchmark Matching – developing a fragrance based on an existing reference sample, with GC-MS analysis support when useful.

Customer-Owned Formula Manufacturing – producing samples and bulk fragrance according to a formula already owned and supplied by the customer.

Understanding which model fits your project can save considerable time during sampling, testing, and commercial production.

1. Custom Fragrance Development: When You Have a Product Idea but No Formula

The first situation is common among brands, OEM/ODM manufacturers, and companies launching a new product.

The customer knows what they want to make, but does not yet have a finished fragrance formula.

For example, the project may involve:

• Laundry detergent
• Fabric softener
• Dishwashing liquid
• Body wash
• Air care products
• Scented candles
• Fine fragrance or perfume products

The customer may already have a general fragrance direction, such as white tea, floral musk, fresh citrus, woody amber, clean cotton, or a more perfume-inspired scent.

A useful fragrance brief can also include:

• Final product type
• Target market
• Desired scent strength
• Target fragrance style
• Cost range
• Expected dosage
• Performance requirements
• Reference products or scent samples

This type of project is Custom Fragrance Development.

The perfumer develops fragrance samples based on the brief, while also considering the final application.

This is important because the same fragrance idea may need to be designed differently for a perfume, laundry detergent, fabric softener, candle, or room spray.

After receiving the samples, the customer can test them in the actual product base and provide feedback. The fragrance can then be adjusted for scent character, diffusion, longevity, cost, or formula compatibility.

Custom fragrance development is therefore not simply about creating a fragrance that smells good. The goal is to develop a fragrance that fits the product, application system, performance target, price positioning, and intended market.

2. Benchmark Matching: When You Have a Reference Sample but No Formula

The second situation is different.

The customer does not have the original fragrance formula, but already has an existing fragrance, market sample, or target scent that they would like to use as a development reference.

This type of project is better suited to Benchmark Matching.

The development process normally begins with an olfactive evaluation. A perfumer analyzes the overall scent profile, top, heart, and base structure, diffusion, dry down, and key olfactive characteristics of the reference sample.

For some projects, GC-MS analysis support can also help provide additional information about the major volatile components present in the sample.

However, GC-MS should be understood as an analytical support tool—not as a machine that automatically produces the complete original fragrance formula.

A fragrance may contain many raw materials at very different concentrations. Some components may be present only at trace levels, while co-elution, isomers, complex natural materials, and other analytical limitations can make interpretation more difficult.

For this reason, successful benchmark development normally combines:

Olfactive evaluation + GC-MS analysis support + perfumer expertise + formula adjustment + application testing

The final result still depends on the perfumer’s interpretation, raw material selection, proportions, trial formulations, and testing in the customer’s actual application.

Benchmark Matching is therefore very different from manufacturing from a customer-owned formula.

In one case, the supplier is re-developing a fragrance based on a target sample. In the other, the customer has already supplied the actual production formula.

3. Customer-Owned Formula Manufacturing: When You Already Have a Complete Formula

The third model is for customers who have already completed fragrance development and own a mature formula.

These customers may have:

• Their own perfumer
• An internal R&D department
• An established fragrance formula already in commercial use
• A formula developed by an authorized technical partner

They are not looking for a supplier to redesign the fragrance.

Instead, they need a manufacturing partner who can first reproduce the formula at laboratory scale, allow them to test the result, and then manufacture it consistently in bulk.

This model can be described as:

Customer-Owned Formula Manufacturing

or, depending on the project,

Fragrance Contract Manufacturing / Toll Manufacturing

A typical workflow is:

Customer Formula & Specifications → Raw Material Review → Laboratory Sample → Customer Testing → Sample Approval → Bulk Manufacturing

The first step is to review the formula and production requirements.

This may include checking:

• Raw material names and specifications
• Required grades or approved suppliers
• Raw material availability
• Regulatory status
• Production feasibility
• Target physical specifications
• Special processing requirements

If an exact raw material is unavailable, discontinued, or needs to be replaced with another specification, the substitution should not simply be made without discussion.

Any relevant change should first be confirmed with the customer.

After the technical review, a laboratory sample can be made according to the supplied formula.

The customer may then compare the sample with the original fragrance and evaluate factors such as:

• Odor profile
• Color and appearance
• Relative density
• Refractive index, where applicable
• Performance in the final product
• Storage stability
• Batch-to-batch consistency

Once the sample has been approved, the project can move toward bulk production.

For this type of cooperation, the manufacturer’s main value is not to redesign the fragrance.

It is to produce the customer’s established formula accurately, consistently, and repeatably.

Why Would a Customer With an Existing Formula Need a New Manufacturing Partner?

Owning a mature fragrance formula does not mean a company will always use only one manufacturer.

There are many reasons a customer may look for an additional production partner.

A company may want to:

• Establish a second supplier and reduce supply-chain risk
• Improve lead times
• Increase production capacity
• Review manufacturing costs
• Find a more suitable MOQ
• Establish an additional manufacturing source in China or Asia

Some customers already have their own technical and perfumery capabilities but want to separate formula development from industrial manufacturing.

For these customers, the key requirement is not a new fragrance concept. It is reliable formula execution, raw material control, production consistency, and confidentiality.

Who Owns a Customer-Supplied Fragrance Formula?

For a complete fragrance formula supplied by the customer, the formula remains the customer’s property.

The manufacturer uses the formula only for the agreed sampling and production project and does not automatically obtain ownership simply by manufacturing the fragrance.

For companies with proprietary fragrance technology, confidentiality is often one of the most important considerations when selecting a manufacturing partner.

Depending on the project, the parties may define matters such as:

• Formula ownership
• Authorized use of the formula
• Confidentiality obligations
• Access to formula information
• Treatment of technical information after the project ends

An NDA or other confidentiality agreement can also be used when required.

At the same time, the customer should confirm that it owns the supplied formula or is legally authorized to use it for manufacturing.

If the customer only has a third-party reference sample but does not own the formula, the project should normally be evaluated as a Benchmark Matching project rather than Customer-Owned Formula Manufacturing.

Three Fragrance Project Models at a Glance

Clearly explaining which situation applies at the beginning of the inquiry can make the development process much more efficient.

What Technical Documents May Be Needed Before Bulk Production?

Fragrance approval is only one part of a commercial project.

Before bulk production, customers may also need technical and regulatory documentation depending on the fragrance, final application, and target market, including SDS/MSDS, IFRA documentation, COA, and allergen information.

Common documents can include:

SDS / MSDS

A Safety Data Sheet provides information related to product handling, storage, safety, hazards, and transportation.

The term MSDS is still widely used by many customers, although SDS is the more current terminology.

IFRA Documentation

An IFRA Statement or Certificate of Conformity, where applicable, needs to be prepared according to the fragrance and its intended end use.

This is important because perfume, laundry detergent, fabric softener, air care, personal care, and other applications may fall under different IFRA categories and may have different maximum use levels.

IFRA documentation should therefore not be treated as one universal certificate that applies to every possible application.

COA

A Certificate of Analysis can provide batch-specific quality information.

Depending on the agreed specification, this may include items such as appearance, color, relative density, refractive index, or other quality-control parameters.

Allergen Information

An Allergen Declaration may also be required depending on the formula, application, and regulatory requirements of the destination market.

For customer-owned formula manufacturing, these documents need to be based on the final confirmed formula and the actual raw materials used in production.

If the customer has specific regulatory, specification, or document-format requirements, it is better to confirm them during the sampling stage rather than after the formula has already been approved.

What Happens if a Raw Material or Regulation Changes?

Long-term fragrance manufacturing also requires change management.

Raw materials can become unavailable, suppliers may change specifications, and regulatory requirements can evolve.

If a change may affect the fragrance profile, product performance, cost, or regulatory status, the customer should be informed and, where necessary, a new sample should be evaluated before implementation.

This is particularly important for customer-owned formula projects.

Changing an ingredient or its dosage without customer approval may cause the manufactured fragrance to move away from the agreed formula and may also affect the customer’s own product specifications or regulatory documentation.

Consistent manufacturing therefore means more than simply making each batch smell similar. It also requires appropriate control over raw materials, specifications, and formula changes.

How Gar Aromas® Supports Different Fragrance Projects

Gar Aromas® can support customers at different stages of fragrance development.

For customers who have a product concept and scent direction but no formula, we can support Custom Fragrance Development according to the application, scent brief, target market, performance requirements, and budget.

For customers who have a reference fragrance but no complete formula, we can support Benchmark Matching, combining perfumer evaluation, GC-MS analysis support when appropriate, formulation work, and sample testing.

For customers who already own a mature fragrance formula, we can evaluate Customer-Owned Formula Manufacturing. After reviewing the raw materials and production feasibility, we can prepare a laboratory sample according to the supplied formula. Once the customer approves the sample, the project can proceed toward bulk production.

For customer-supplied proprietary formulas, ownership remains with the customer, with confidentiality and permitted use defined according to the project agreement.

Depending on the project, Gar Aromas® can also support technical documentation such as SDS/MSDS, IFRA documentation, COA, and allergen information.

If you are developing a new fragrance, have a reference sample that you want to benchmark, or already own a mature fragrance formula and are looking for another manufacturing partner, contact Gar Aromas® with your project requirements.

The first step is to determine whether your project is best suited to Custom Fragrance Development, Benchmark Matching, or Customer-Owned Formula Manufacturing—and then move into sampling, evaluation, and production accordingly.
