NaturaRose, a leading mid-to-high-end skincare and salon perfume brand in Southern Italy, focuses on organic natural product lines including premium rose essence cream, single-note perfumes and salon body oils sold at luxury malls in Milan, high-end spas in Rome and organic beauty retailers nationwide across Italy. Its raw materials comply with EU Cosmetics Regulation 1223, IFRA 50th Edition fragrance specifications and Italy’s local organic beauty access standards. The brand long sourced original natural geraniol from Givaudan. To cut raw material costs and shorten supply lead times, the client first mass-adopted domestic premium geraniol to replace imported raw materials. After mass production launch, four major technical failures emerged: off-odor perfume, oxidative sensitization during cream storage, stratification during emulsification and excessive loss at high-temperature batching. Domestic suppliers could only provide national standard raw material test reports and lacked R&D capacity for terminal cosmetic formulations, making them unable to deliver solutions covering raw material modification, formula adjustment and workshop process optimization. Approximately 4 tons of semi-finished products faced scrapping losses. The client entrusted HiSiaddi to resolve full-chain production technical challenges across four dimensions: raw material traceability, formula optimization, workshop SOP revision and refined raw material calibration. After rectification, finished product quality matched original Givaudan raw materials, and an annual fixed procurement order of 35 tons was finalized.
The client directly replicated the addition ratio, feeding temperature and emulsification process of imported European geraniol for domestic raw material production. Restricted by raw material sources and rectification refinement depth, domestic generic geraniol exhibited obvious gaps versus imported original materials in impurities, isomer ratios and oxidation resistance, leading to mass disqualification across three core product lines:
Original Givaudan geraniol undergoes multi-stage precise rectification with strict control of neroli, citronellol and trace terpene impurities. Domestic raw materials contain 11.2% neroli (client formula standard: 4%~5%) and residual trace limonene impurities, generating prominent terpene off-notes that disrupt the brand’s mild rose base. At identical addition dosages, the top notes become harsh, and multiple perfume batches failed brand internal quality control sensory evaluation.
Domestic geraniol has a peroxide value of 7.2 mmol/L, far exceeding the imported raw material standard of ≤2.5 mmol/L. Peroxides continuously oxidize during storage to generate sensitizing derivatives; the cream’s weakly acidic emulsification system accelerates fragrance degradation, leading to broken emulsion stratification within the shelf life and excessive EU allergen test results, disqualifying products for sale in Italian terminal retail channels.
The client’s original process added geraniol during the 75°C oil-water co-homogenization stage. Domestic raw materials contain trace high-boiling polymer impurities that trigger flocculation reactions with plant oils upon high-temperature contact with emulsification substrates, destabilizing the emulsion system and rendering 1.8 tons of cream semi-finished product per batch unfit for sale.
Domestic geraniol features disordered distillate fractions with high levels of low-boiling light components. During 85°C compounding stirring, light fragrance components volatilize rapidly, creating inconsistent rose aroma intensity across batches even with identical raw material addition ratios and preventing standardized mass production.
Domestic raw material manufacturers only guaranteed compliance with national standard geraniol content and refused to adjust rectification processes or provide expertise on cosmetic compounding logic. The client’s new product launch schedule was delayed, with direct semi-finished product losses exceeding EUR 93,000.
Equipped with dedicated flavorists, cosmetic formulation engineers and fragrance process technicians, HiSiaddi adopted a closed-loop solution: upstream raw material customized refinement + terminal formula fine-tuning + workshop production process revision + warehouse storage control upgrade. While coordinating raw material factories to optimize geraniol refining parameters, remote technical support was provided to the client’s Italian R&D department and production workshop for formula and operational standard optimization.
1. HiSiaddi collaborated with manufacturing factories to retrofit two-stage negative-pressure molecular distillation equipment for precise fraction cutting, stripping excess neroli, citronellol and terpene impurities to achieve finished geraniol ≥93.8% with neroli locked within 4.3%~4.9%, matching the client’s formula design values.
2. A low-temperature nitrogen-sealed storage procedure was added at the final stage, with recrystallization impurity reduction controlling peroxide values at 2.2~2.7 mmol/L and removing oxidation-prone precursor impurities.
3. Finished products were repackaged in 10L light-proof nitrogen-purged stainless steel drums to isolate air and moisture oxidation. Each batch is accompanied by full-component GC chromatograms and SGS EU-standard test reports.
1. Rose Single-Note Perfume Formula Optimization Geraniol addition dosage reduced from original 0.32% to 0.25%, with 0.06% natural rose absolute compounded to balance aroma, offsetting the floral weakness of domestic raw materials and neutralizing sharp terpene notes. A low-temperature ethanol pre-dissolution method was adopted: fragrances are fully dissolved in room-temperature anhydrous ethanol before blending into perfume base liquid to avoid high-temperature volatilization loss.
2. Organic Cream Formula Optimization Geraniol feeding was delayed from the 75°C high-temperature stage to post-emulsification cooling at 48°C. 0.03% natural vitamin E antioxidant auxiliary was added to the formula to synergistically inhibit geraniol oxidation into sensitizing substances, and cream oil ratios were optimized to improve system compatibility, eliminating storage stratification and yellowing issues.
3. SPA Body Oil Optimization A carrier oil pre-coating process was adopted: geraniol is pre-encapsulated with a small amount of sweet almond oil at room temperature before addition to the 85°C hot oil system, locking low-boiling components to control fragrance volatilization loss and standardize batch aroma consistency with fixed feeding ratios.
1. Abolished direct feeding of dry powder/stock solution and rolled out a universal pre-dissolved mother liquor feeding standard. HiSiaddi issued bilingual Italian-English operation guides.
2. Raw material warehouse storage standards: Customized geraniol stored in constant-temperature (18~22°C) light-shielded warehouses; opened drums must be fully consumed within 7 days, prohibiting high-temperature open storage that accelerates oxidation.
3. Online video training for workshop operators and quality control staff covering geraniol isomers, oxidation characteristics and acid-base compatibility taboos, unifying feeding control standards across the entire factory.
Four additional internal control indicators were added on top of national standards: neroli content limit, peroxide value, light terpene impurities and 45-day 60°C accelerated stability testing. All incoming raw materials must be accompanied by third-party special test reports, with unqualified raw materials rejected at intake to avoid quality fluctuations at the source.
1. Multi-Category Sample Validation Optimized customized geraniol samples of each specification (4kg) were air-shipped to NaturaRose’s Italian R&D laboratory for long-term room-temperature storage (3 months), accelerated aging testing, skin patch testing and perfume sensory blind evaluation. Perfume aroma, cream stability and sensitization indicators all matched original Givaudan reference samples.
2. Rework of Disqualified Semi-Finished Products Using the optimized new formula, nearly 4 tons of defective semi-finished inventory were reprocessed with supplementary auxiliary materials to meet all standards, recovering massive scrapping losses.
3. Formal Order Delivery First trial order breakdown: 12 tons perfume-grade, 15 tons cream-grade, 8 tons body oil-grade, totaling 35 tons shipped from Shanghai Port to Genoa Port, Italy. HiSiaddi provided supporting IFRA compliance statements, CPSR safety assessment reports and free sales certificates for smooth Italian customs clearance and warehouse storage.
1. Recovered EUR 93,000 in semi-finished scrapping losses, enabling timely new product launch across Italian high-end beauty channels. Comprehensive procurement cost for customized domestic geraniol dropped by 31% versus original Givaudan imports, and ocean transit lead time was shortened from 52 days to 21 days. A 38-ton annual long-term order was renewed for the following year.
2. Established exclusive formulation systems and raw material acceptance specifications tailored to domestic geraniol, with its Spanish and Croatian subsidiaries launching domestic geraniol replacement projects simultaneously.
Leveraging the benchmark Italian high-end beauty client, the factory refined production processes for high-end refined geraniol, escaping low-price generic product homogenization competition. This customized grade achieved a 37% export premium and secured follow-up orders from multiple mid-to-high-end aromatherapy brands in Portugal and Greece.
Established a standardized technical service package covering geraniol raw material rectification improvement, cosmetic formula optimization, workshop process implementation and internal control standard formulation. Subsequent fragrance selection and process rectification projects were undertaken for premium beauty enterprises in Finland and Denmark in Northern Europe.
1. Industry Pain Point: Most domestic geraniol manufacturers focus on national-standard mass production, only controlling basic indicators such as main content, lacking terminal cosmetic formulation R&D expertise and insufficient understanding of the impact of varying pH and temperature environments in perfumes and creams on fragrance stability. Long-term use of refined fragrances from international manufacturers by mid-to-high-end European and American beauty brands creates mass production failures when directly replicating imported formulas with domestic raw materials, resulting in severe technical information disconnect between upstream and downstream supply chains.
2. Procurement Characteristics of Mid-to-High-End Clients: Brands carry high product premiums, prioritizing stable finished product aroma and compliance safety above raw material procurement price, willing to bear reasonable costs for raw material customization and formula fine-tuning. Core demand: finished product sensory experience and safety fully equivalent to imported original raw materials.
3. Core Value of HiSiaddi: As a third-party foreign trade service provider bridging technical barriers between raw material factories and overseas terminal manufacturers, delivering full-chain rectification covering raw materials, formulas, production and warehousing to resolve mass production technical pain points during domestic fragrance import replacement.
