The cooperating client is Netherlands Noble Scent, a renowned mid-to-high-end salon fragrance and premium home aromatherapy brand in Western Europe specializing in forest herbal and retro pastoral scents, with offline presence in high-end beauty retailers and star hotels across multiple countries. The brand fully complies with IFRA Version 51, EU REACH regulation and allergen limit standards, and synthetic oakmoss acts as the core base material for multiple classic fragrance lines.
After switching to a new batch of synthetic oakmoss, the client encountered successive abnormalities during formula compounding, production processing and finished product storage: distorted fragrance layers, strange off-odors post-compounding, altered fragrance under heating during production, thickening and caking of raw materials at low temperatures, severe equipment wall adhesion, and cross-contamination of scents during production of different fragrance lines. Repeated adjustments to formula ratios, temperature control parameters and stirring processes by the client’s internal R&D and production teams failed to resolve the issues, resulting in raw material losses, reduced production capacity and suspended sampling for multiple new products. The client subsequently commissioned HiSiaddi’s technical team to conduct problem diagnosis and full-process optimization rectification.
Combining raw material test reports, the client’s formula system, workshop production operating conditions and storage environments, HiSiaddi analyzed and sorted out four core technical issues:
High byproduct content in the batch of synthetic oakmoss resulted in a prominent inherent chemical odor. When blended with floral and herbal fragrance bases, the natural damp mossy green notes were masked, creating a dull, disorganized overall fragrance profile; certain mixing ratios even generated rancid off-odors that completely deviated from the brand’s intended style.
The client’s fragrance production requires a constant-temperature maturation stage at 40–43℃. Within this temperature range, low-boiling residual intermediates in the raw material decomposed and released irritating odors, directly rendering entire batches of finished products unusable.
Winter warehousing and cross-border transportation temperatures in the Netherlands and neighboring regions often drop to approximately 0℃, triggering aggregation of internal components in synthetic oakmoss. The raw material viscosity surges, with partial caking occurring, hindering feeding and causing turbidity and sediment in perfume stock solutions that damage finished product appearance quality.
Elevated base viscosity of the raw material led to heavy adhesion on the inner walls of mixing kettles, conveying pipelines and filling equipment, pushing the single-batch raw material loss rate to 10.5%. Additionally, the strong adhesive aroma of oakmoss lingered after production, requiring prolonged equipment cleaning downtime when switching to fruit or citrus fragrance lines and drastically lowering production efficiency.
HiSiaddi assembled a dedicated team of fragrance application engineers, formulators and process optimization specialists. Without altering the brand’s original fragrance positioning, replacing core production equipment or violating EU safety limits, four-dimensional rectification solutions were rolled out covering raw material refining, formula adaptation, process adjustment and on-site management.
Coordinated upstream factories to conduct secondary deep processing on existing inventory raw materials via high-vacuum multi-stage molecular distillation technology, which selectively removed residual intermediates, low-boiling decomposable substances and sensitizing byproducts.
Post-refining testing confirmed harmful byproduct contents fell below detection limits, harsh chemical odors were fully eliminated, and pure damp mossy green notes with herbal base tones became prominent. Compatibility with all fragrance bases improved significantly, fundamentally resolving off-odor generation during compounding and fragrance deterioration under high heat.
· Optimized feeding sequence: Fully mix alcohol and primary fragrance bases and cool to below 32℃ before adding synthetic oakmoss to avoid prolonged exposure of raw materials to high temperatures.
· Tuned compounding ratios: Fine-tuned auxiliary aromatic material proportions based on the refined raw material’s aroma characteristics to amplify natural mossy texture and neutralize heavy notes, restoring the brand’s classic fragrance profile.
· Multi-round sampling testing: Dozens of formula samples were produced and tested to finalize the optimal mixing ratio, delivering full, consistent fragrance layers free of abnormal odors post-compounding.
EU-certified bio-based rheology regulators compliant with regulations were added to improve raw material crystallization and flow properties. Simulated cold resistance testing showed the raw material retained excellent fluidity with no caking or delamination after 20 days of storage at 0℃, yielding crystal-clear perfume finished products free of sediment defects.
The fragrance maturation temperature was lowered to 38–40℃ to reduce raw material exposure to high heat, while additional temperature monitoring points were installed on production equipment to eliminate local overheating and completely resolve off-odor generation from thermal decomposition.
Raw material viscosity was further optimized via refining technology, while food-grade anti-adhesive treatment was applied to reaction kettle and pipeline inner walls, with an additional 2-minute wall scraping operation added at the end of stirring procedures. Post-rectification, the comprehensive raw material loss rate dropped below 3.2%.
Separate pipelines and filling equipment were designated for forest herbal, floral and citrus fragrance lines to eliminate shared pipeline usage. Standardized cleaning procedures were formulated, with dedicated base solvent circulating flushing of pipelines prior to cross-category production to fully remove residual fragrances, cutting equipment cleaning time by 40% and restoring normal production capacity.
HiSiaddi engineers conducted bilingual practical training at the client’s production facility, clarifying standard operating parameters including feeding sequence, temperature ranges, stirring rotation speeds and equipment cleaning. Bilingual English-Dutch operating instructions were compiled. Meanwhile, the client was assisted in establishing raw material incoming inspection standards, mandating aroma, stability and viscosity testing for every batch to predict quality risks in advance.
· Small-batch trial production: Seven consecutive production batches passed all aroma, appearance, stability and loss rate inspections and received approval from the R&D department.
· Full-line resumption: The client fully adopted the revised formulas and operating specifications. Over thirty consecutive mass production batches exhibited zero recurrence of all technical issues, maintaining a 100% finished product pass rate.
· End-market feedback: Finished products received consistent positive feedback on pure, stable natural fragrance from offline retail stores and premium partner venues, with steadily improving end-consumer reputation.
· Optimized production costs: Simultaneous reductions in raw material loss, labor and energy consumption delivered notable improvements in production efficiency.
· Controllable quality risks: A dual system of raw material sampling inspection and in-process management was established, drastically improving the stability of subsequent raw material supplies.
· Deep client recognition: The client’s technical director stated that HiSiaddi possesses comprehensive expertise in the physical and chemical properties of synthetic oakmoss and European fragrance production operating conditions, delivering pragmatic and efficient solutions alongside long-term control mechanisms fully aligned with the brand’s premium positioning.
· Deepened cooperation: The client designated HiSiaddi as its core supplier of synthetic oakmoss and expanded annual procurement volume; all new product R&D phases now involve early consultation with HiSiaddi for raw material adaptation and process risk prediction.
Mid-to-high-end European fragrance brands utilizing synthetic oakmoss prioritize four core dimensions: pure fragrance, formula compatibility, wide temperature stability and production adaptability, fundamentally differing from low-end daily chemical products that only focus on basic indicators and low costs.
This service adopted a combined solution of "raw material refining + formula optimization + process adjustment + process control" to complete comprehensive rectification at low cost, rapidly resolving immediate production issues while establishing long-term quality assurance mechanisms. Supported by professional fragrance application technology and on-site service capabilities, HiSiaddi consistently meets the stringent premium brand requirements for quality, stability and production efficiency, further consolidating cooperative foundations between both parties.
