LubriFine is a leading mid-to-high-end lubricant raw material manufacturer in Europe. Its core products include raw materials for high-performance lithium complex greases, cosmetic ointment bases, and sustained-release pharmaceutical ointment substrates. It supplies specialty lubricant plants of Shell Europe and local organic beauty brands in the Netherlands. All its products comply with EU REACH, CLP, EU cosmetic raw material regulations, and FDA indirect food contact standards.
The enterprise has long purchased refined 12-hydroxystearic acid from Cognis Germany. However, surging overseas raw material prices, a minimum order quantity of 40 tons for customized products, and sea transit times exceeding 75 days drove the client to develop custom-grade 12-hydroxystearic acid manufactured in China. Its annual demand stands at 150 tons, with an initial trial custom order of 22 tons.
1. Customized Main Component & Hydroxyl Value: 12-hydroxystearic acid content ≥92.5%, hydroxyl value 158±2mgKOH/g. Conventional domestic industrial grades only reach 85%~89% purity with hydroxyl value fluctuations of ±6mgKOH/g, failing to meet formulation requirements for high-end lubricant thickeners.
2. Precision Impurity Control: Free stearic acid ≤2.2%, iodine value ≤2.8gI₂/100g, moisture ≤0.05%; heavy metals Pb, As <0.1ppm; residual catalysts (zinc, aluminum ions) ≤2ppm. Low-carbon fatty acid impurities are prohibited to meet access standards for pharmaceutical and organic cosmetic raw materials.
3. Customized Crystallization & Physical Properties: Congealing point 72.5±1℃, fine crystal grains without massive agglomeration; fully clear with no suspended matter after melting at 60℃. Conventional domestic products turn turbid after melting and tend to precipitate impurities during high-temperature storage.
4. Customized Raw Material Source & Environmental Protection: Feedstock limited to natural fatty acids derived from hydrogenated palm kernel oil; waste gutter oil and recycled waste oils are forbidden. 28-day biodegradability ≥82%. A full set of EU compliance documents is required for the client’s organic product filing.
The client independently contacted three leading domestic 12-hydroxystearic acid manufacturers (Jiangsu Jinke, Anhui Keyuan, Shandong Youbao), yet the project stalled for the following reasons:
1. Factories primarily mass-produce standard national standard grades and are reluctant to suspend continuous production lines for small-batch non-standard customization of 22 tons. Process modification costs pushed quotations up by 38%.
2. Most manufacturers utilize mixed industrial oil feedstocks and cannot source food-grade imported palm-based fatty acids separately, failing the client’s traceability requirements for raw material origins.
3. Facilities lack supporting deep hydrogenation and molecular distillation refining processes, making it impossible to reduce free acid and trace metal impurities to the required levels.
4. Factories can only provide Chinese-language national standard COAs, without EU-compliant biodegradation reports or complete REACH documentation. The Dutch R&D team excels in formulation application but lacks familiarity with China’s oil deep processing industrial chain. Three rounds of sample testing yielded products failing physical property standards, halting customization work entirely. The client fully entrusted HiSiaddi to coordinate the full workflow covering raw material procurement, customized process design, pilot trial mass production, and compliance management.
HiSiaddi assembled a team of oleochemical engineers, raw material procurement specialists, and EU compliance officers, and partnered with manufacturers equipped with flexible batch reactor refining capacity. The project was executed in four stages: targeted upstream raw material sourcing → formulation & process tuning → small-batch trial → pilot test → formal mass production.
HiSiaddi coordinated with domestic agents of Southeast Asian palm oil refineries to procure food-grade refined hydrogenated palm fatty acids uniformly, complete with certificates of origin and customs declaration documents for full traceability, eliminating adulteration with miscellaneous oils. Raw materials underwent GC component testing upon arrival to remove short-chain mixed acids, preventing excessive impurity levels in subsequent production.
1. We coordinated the factory to pause mass-production continuous lines and deploy a dedicated 3m³ batch reactor, optimizing core process parameters for epoxidation, hydrolysis, and hydrogenation stages: precise control of reaction temperature, catalyst dosage, and reaction duration. A two-stage short-path molecular distillation procedure was added at the later stage to remove free stearic acid, unreacted feedstock, and residual metal catalysts under negative pressure.
2. Six rounds of small-batch sample adjustments were completed in total: the first three batches suffered from excessive free acid and insufficient hydroxyl value. After optimizing hydrolysis holding time and vacuum devolatilization parameters, the 6th sample delivered the following test results: 12-hydroxystearic acid content 93.1%, hydroxyl value 157.3mgKOH/g, free stearic acid 2.01%, iodine value 2.5gI₂/100g — all falling within the client’s tolerance range. The molten product at 60℃ was completely transparent without impurities, with a congealing point of 72.3℃.
The pilot test replicated small-batch process parameters with strict control over heating curves and distillation negative pressure, resulting in batch index fluctuations of less than ±1%. Samples were shipped to the Netherlands for formulation trials in three categories: lubricating grease, cosmetic ointment, and pharmaceutical substrate. After 90 days of cold-heat cycling storage (-10℃~80℃), no delamination or recrystallization occurred, with consistency and stability matching original Cognis products.
During mass production, HiSiaddi stationed on-site QC personnel. Production was split into four batches, with separate sampling from each tank for full CNAS-certified testing and English COA issuance. Finished products were packed in PE-lined iron drums sealed with nitrogen to avoid moisture absorption and oxidation during transportation and storage.
1. A third-party laboratory conducted biodegradability testing in accordance with OECD301B standards and issued an English test report with a measured biodegradation rate of 83.6%.
2. Leveraging a registered EU REACH Only Representative, we completed monomer REACH registration for the product and a 253-item SVHC screening report. Bilingual English-Dutch 16-section compliant SDS documents and GHS outer packaging warning labels were prepared in line with CLP regulations.
3. A complete traceability archive for palm feedstock origins was compiled to satisfy EU raw material filing audits for the client’s cosmetic and pharmaceutical lines.
1. Initial Order Fulfillment: The 22-ton customized cargo was shipped from Shanghai Port to Rotterdam. All customs documentation passed Dutch customs inspection in a single review. After production launch, the specialty lubricating grease successfully passed incoming material audits by Shell, and cosmetic raw materials cleared EU organic raw material warehousing testing. Localized procurement costs dropped by 30.2% compared to imported Cognis materials, and transit time was shortened from 75 days to 33 days.
2. Annual Long-Term Contract Signing: LubriFine canceled its procurement contract with the European original manufacturer and signed an annual 150-ton procurement framework agreement with HiSiaddi, with quarterly batch production scheduling. Later, the client’s high-end anti-rust additive product line required modified 12-hydroxystearic acid, which was also entrusted to HiSiaddi for customized development.
1. Industry Pain Points: Domestic manufacturers of 12-hydroxystearic acid focus on large-scale production of standard national standard grades, with scarce flexible customized production capacity. Factories are reluctant to adjust processes for small-batch non-standard orders. Most producers utilize low-cost mixed industrial oils, failing to meet the natural feedstock and ultra-low impurity standards required by mid-to-high-end European and American clients. Additionally, manufacturers generally lack supporting capabilities for EU compliance documentation.
2. Mid-to-High-End Client Demand Characteristics: The product covers three high-end sectors: lubricants, cosmetics, and pharmaceuticals. Purity, impurity limits, raw material traceability, and environmental compliance are equally critical. Non-compliant raw materials will cause downstream end products to fail audits by brand owners and EU supermarkets, resulting in losses far exceeding raw material price differences.
3. Core Value of HiSiaddi: We connect high-end imported feedstock sourcing, flexible customized factory processes, full-process quality control, and cross-border compliance support across the entire industrial chain. Acting as a technical bridge between overseas R&D teams and domestic oil processing manufacturers, we successfully realized localized customized substitution of high-end raw materials.
