The cooperating client is Belgium Royal Fragrance, a renowned mid-to-high-end salon and home fragrance brand in Europe. Specializing in retro forest and herbal scents, its products are popular across Western Europe including Belgium, the Netherlands and Luxembourg. The brand fully complies with IFRA Version 51, EU REACH regulation and comprehensive allergen control standards. Synthetic oakmoss serves as the core base material for the brand’s forest-themed fragrances and vintage colognes, as natural oakmoss has been fully banned under EU regulatory restrictions. The brand has shifted to compliant synthetic oakmoss as a replacement.
In July 2026, the client launched its limited-edition collection "Forest Secret", requiring customized production of 120kg high-compliance synthetic oakmoss with the following specifications:
· Fragrance: Reproduce the damp green notes of natural oakmoss with subtle mossy animalic undertones and a faint woody base; reduce the chemical odor typical of conventional synthetic variants for a mild, natural aroma with long-lasting retention.
· Composition Indicators: Main component content ≥92%; prohibited substances including phthalates and polycyclic aromatic hydrocarbons; single sensitizing impurity content ＜0.05%.
· Physical & Chemical Properties: No solidification at -5℃; stable fragrance without deviation during the 45℃ fragrance maturation process; high compatibility when compounded with floral and herbal bases.
· Confidentiality & Mass Production: Exclusive formula and production process to be kept strictly confidential; stable batch replication required; full delivery of R&D, trial production, mass production and complete compliance documents within 38 days.
The client previously collaborated with multiple domestic manufacturers but encountered widespread issues including distorted fragrance, excessive sensitizing impurities, poor temperature stability, and reluctance to undertake small-batch custom formulation adjustments. Ultimately, the client fully entrusted HiSiaddi to deliver this customized project.
Conventional synthetic oakmoss delivers overly singular green notes with prominent chemical odors, failing to replicate the multi-layered damp mossy aroma of natural oakmoss. Minor adjustments to component ratios easily unbalance the fragrance, resulting in overly sharp green notes or thin, lacking animalic undertones.
The EU enforces strict limit controls on sensitizing substances and harmful additives in oakmoss fragrances. Manufacturers must simultaneously maintain high main component purity and limit trace sensitizing impurities below 0.05%, a threshold difficult to achieve via standard synthetic processes.
Warehousing and long-distance transportation in Western Europe can drop to -5℃ in winter, while fragrance production includes a 45℃ constant-temperature maturation stage. Ordinary products tend to solidify at low temperatures or develop altered fragrances under high heat, making them incompatible with the client’s full-process usage scenarios.
The 120kg order qualifies as a high-end small-batch custom project, which incurs high costs for independent process adjustments on standard factory production lines. Meanwhile, the client mandates strict confidentiality for formulas and process parameters, creating risks of technical leakage.
Targeted at the European high-end market, the limited-edition collection requires concurrent issuance of IFRA Version 51 statements, REACH-SVHC screening reports and full allergen test reports, with document formats and languages meeting EU audit requirements.
HiSiaddi assembled a dedicated team consisting of synthetic fragrance engineers, senior perfumers, compliance specialists and production control managers, collaborating with fine chemical R&D laboratories and custom manufacturing factories to implement phased solutions. All deliverables were completed within 35 days, ahead of the agreed timeline.
Abandoning generic synthetic formulas, multi-component esters and terpene derivatives were selected as the core framework to mimic the molecular aroma structure of natural oakmoss and fundamentally reduce harsh chemical odors. A total of 26 sample iterations were conducted to fine-tune component ratios, ultimately finalizing the exclusive fragrance profile dominated by damp green top notes, mossy animalic middle notes and subtle woody base notes, delivering a rich, natural aroma highly consistent with natural oakmoss.
A combined catalytic synthesis and multi-stage rectification process was adopted. The catalyst system was optimized during synthesis to reduce byproduct generation, followed by high-vacuum rectification to separate sensitizing impurities and residual intermediates in a targeted manner. Final testing confirmed single sensitizing impurity content below 0.04%, exceeding the client’s specified limit.
Trace bio-based conditioning ingredients compliant with regulations were added to optimize the product’s crystallization characteristics. Continuous cold resistance testing was conducted: the product maintained normal fluidity with no solidification or delamination after 20 days of storage at -5℃.
Raw material monomers with superior thermal stability were selected to improve overall heat resistance. After 48 hours of constant-temperature testing at 45℃, no significant changes were observed in fragrance layers or component ratios, satisfying the requirements of the fragrance maturation process.
Hundreds of compounding trials were carried out with the client’s existing floral and herbal fragrance bases, verifying seamless blending without repulsion or off-odor generation.
A dedicated production line was coordinated at the factory, with equipment thoroughly cleaned and disinfected in advance to eliminate cross-contamination from other products. The finalized formula and process parameters were followed throughout production, with on-site dedicated supervisors sampling ingredients and aroma every 2 hours.
Formal non-disclosure agreements were signed with the factory. Custom formulas and process parameters were encrypted and archived, accessible only to HiSiaddi’s dedicated project team and the client. Separate files were created for this exclusive batch, with no identical products shared externally to guarantee the client’s exclusive usage rights.
Upon completion of finished products, samples were sent to a CNAS-accredited laboratory for comprehensive testing. The main component content stabilized at 92.6%, and all controlled substances complied with EU standards, with official test reports issued.
Full sets of English compliance materials were expedited, including IFRA Version 51 conformity statements, REACH-SVHC Substances of Very High Concern screening reports, 80-item full allergen test reports, heavy metal and residual solvent test reports. All reports are verifiable on official EU platforms.
A full-process batch archive system covering "formulation – synthesis – rectification – quality inspection – delivery" was established, recording process parameters for every production stage to enable full traceability per batch, aligning with the traceability management standards of high-end brands.
Light-proof, sealed food-grade containers were used for filling, printed with bilingual English-French exclusive labels marked with batch numbers, compliance identifiers and traceability codes. Outer packaging utilized EU eco-friendly materials with shipping warning labels affixed to accommodate cross-border sea transportation.
Blind testing by the client’s perfumery team confirmed the finished product delivers multi-layered, mild natural fragrance perfectly matching the design style of the "Forest Secret" collection. All composition and impurity indicators passed inspection, with batch component fluctuations controlled below 0.4%.
All high-low temperature simulation tests and fragrance compounding trials passed successfully. The product remained stable throughout production, warehousing and transportation with no solidification or off-odor issues.
The full set of qualification documents passed one-time review by European customs and the client’s compliance department, enabling seamless warehousing of goods.
After the launch of the limited-edition fragrance formulated with this customized synthetic oakmoss, its natural retro forest aroma earned high praise from premium consumers, and the limited stock sold out rapidly.
A three-year exclusive customized framework agreement was signed between both parties, with annual procurement volume increased to 300kg to lock in exclusive formulas and production capacity.
The client designated HiSiaddi as its core custom supplier for synthetic aromatic raw materials, entrusting HiSiaddi with all subsequent raw material customization for new forest and herbal fragrance lines.
