After an EPHYON ODM sample, what must be checked before producing a new fragrance version?

After changing a fragrance in a sample, confirm the revised sample version, then review the fragrance information, intended use, packaging text and applicable quality requirements. Both parties should base production on the updated physical sample and documents rather than carrying over the old sample's scent, formulation and labeling conclusions.

First, clarify what has been changed. Is it the intensity of the fragrance, the direction of the scent profile, or switching to a fragrance from another supplier? The brand can provide the original sample number, the experience they wish to adjust, the target sales market, and the expected packaging format to the EPHYON ODM team. EPHYON's publicly available formula customization service supports discussions on fragrance type, cleaning power, pH, viscosity, sampling, and packaging solutions according to specific product categories; complex fragrance formulations require separate confirmation of development time. This way, the communication is not just 'make it a bit more fragrant,' but rather between two comparable sample versions.

The second step is to see whether the fragrance is suitable for the intended use. Standards from the International Fragrance Association may set restrictions, usage limits, or specification conditions for certain fragrance materials, and the limits also depend on the type of finished product. Requesting information from the fragrance supplier regarding the intended use is more useful than just looking at a general 'IFRA compliant' statement; documents provided by the supplier for compliance cannot replace the suitability assessment of the finished product itself. Different products and sales markets may also have additional requirements.

Even if the fragrance has changed, the actual performance of the sample needs to be re-evaluated. Beyond the smell, which aspects need to be rechecked—such as color, appearance, viscosity, and the state after contact with the container—should be determined by the specific formulation and packaging plan. Guidance from the ISO 9001 Auditing Practices Group, jointly supported by ISO and the International Accreditation Forum for design and development audits list design changes, reviews, and verifications as separate control steps: the new version must meet the requirements and also leave confirmation results. For both parties involved, a clear sample number and confirmation record are more reliable than orally saying 'it's about the same as last time.'

The packaging text must also be verified according to the target market. China's Product Quality Law requires that product labeling be truthful and provide necessary information and warnings in Chinese according to the product's characteristics; the UK's Health and Safety Executive has separate labeling rules for fragrances and certain allergenic fragrances on detergents sold in the Great Britain market. The regulations in the two regions cannot be applied interchangeably. If the fragrance or its usage amount changes the information that needs to be provided externally, it should be addressed before the packaging is finalized, rather than waiting to modify it after the finished products are packed.

EPHYON's publicly disclosed OEM process places the confirmation of physical samples before mass production, and production begins only after the packaging documents and materials are confirmed. After an ODM project changes the fragrance, samples, packaging, and schedule can be realigned accordingly; specific testing and delivery conditions are determined by the product plan and mutual agreement. When preparing for communication, bringing the original sample, the target fragrance direction, the target market, and the existing packaging draft can help quickly identify the areas that need modification.
