BelClean is a leading mid-to-high-end precision industrial cleaning enterprise in Western Europe, specializing in strong alkali spray cleaners for automotive precision parts and concentrated degreasing solutions for aerospace aluminum components, supplying BMW and Volvo component factories across Europe. Its products comply with EU REACH, OECD biodegradation, CLP and heavy metal limit regulations, with an annual customized isotridecyl alcohol ethoxylate procurement volume of 260 tons. Previously, the enterprise exclusively sourced customized isotridecyl alcohol ether grades from Clariant Germany.
Amid surging European chemical raw material prices, a minimum order quantity of 38 tons and ocean transit lead times of 72 days, the client sourced domestically manufactured narrow-distribution isotridecyl alcohol ethoxylate (EO8.2) via HiSiaddi. After the first 45-ton shipment arrived at the Belgian plant, production was initiated directly using the original mature Clariant formulation and fully automated closed reactor production lines. Four consecutive days of operation forced full production line shutdown, with nearly 7 tons of semi-finished concentrated cleaning agent delaminated and scrapped. Scheduled delivery deadlines for BMW component factories were delayed. The European R&D team spent three weeks troubleshooting without identifying root causes, fully entrusting HiSiaddi’s technical engineers to conduct on-site technical diagnosis and comprehensive rectification of formulations and production workflows.
Client Limitations: European R&D staff possess expertise in end-use cleaning formulation design but lack familiarity with carbon chain composition, free alcohol residues and EO distribution characteristics of domestic isotridecyl alcohol feedstocks. Domestic suppliers can only guarantee national standard basic data including hydroxyl value and cloud point, lacking downstream cleaning compounding and mass production process R&D capacity; they can only fine-tune raw material hydroxyl values without resolving end-formula compatibility and on-site production anomalies.
The client’s finished concentrated strong alkali solution (system pH 13.2~13.8) exhibited obvious oil-water delamination after 72 hours of ambient storage, with white floc precipitates forming under 5℃ cold storage. BMW factory incoming inspections rejected the batches, blocking factory deployment. Root Cause: Domestic customized isotridecyl alcohol ether contained 0.58% residual free isotridecyl alcohol (vs. ≤0.25% for original Clariant products). Small-molecule free alcohols triggered salting-out reactions with inorganic salts in the strong alkali system under high pH conditions, disrupting micellar structures of non-ionic surfactants. Additionally, the raw material featured broad EO distribution with excessive short-chain low-EO fractions, creating a wide HLB range incompatible with formulations engineered around narrow-distribution imported raw materials, severely degrading alkali resistance stability.
The client’s automated high-pressure spray lines (70bar spray pressure) produced foam heights exceeding 420mm (internal control standard ≤80mm for low-foam requirements). Foam overflow submerged motors and electrical control components, forcing temporary shutdown and maintenance of two spray lines. Trigger Factor: Domestic raw materials contained trace ethylene oxide ring-opening by-products and short-chain polyether impurities that sustained foam stability under high-shear spray conditions. Clariant products underwent multi-stage high-temperature vacuum devolatilization to eliminate such impurities. The original defoamer dosage was calibrated for imported raw materials and lacked adequate suppression performance against domestic raw material impurities.
At identical additive dosages, aluminum precision component degreasing efficiency dropped from the original 98.5% to 89.2%, with watermark residues remaining on workpieces after 120℃ drying, failing aerospace component cleanliness standards. Cause: Domestic isotridecyl alcohol feedstock contained mixed C11/C14 hetero-carbon fractions (imported raw materials maintain C13 purity above 97.5%), creating uneven wetting and penetrating capacity that incomplete oil stripping left trace mineral oil residues forming drying stains on substrate surfaces.
HiSiaddi formed a special technical task force comprising surfactant synthesis engineers, daily chemical formulation engineers and on-site production process specialists. The solution retained the client’s core formulation framework and auxiliary raw material procurement system, implementing closed-loop rectification covering upstream raw material modification, compounding formulation fine-tuning and on-site production SOP optimization at the European factory.
1. Remaining 37 tons of domestic isotridecyl alcohol ether inventory were shipped back to cooperative fine chemical factories for secondary high-temperature negative-pressure deep devolatilization via extended vacuum holding periods to remove residual ethylene oxide small-molecule by-products and free isotridecyl alcohol. Post-refining free alcohol levels fell to 0.23%, fully matching imported raw material limits. Fractions enriched with C11/C14 hetero-carbon components were separated and removed, elevating finished C13 main component purity to 97.8%.
2. Terminal ethylene oxide capping processes were fine-tuned to narrow EO distribution ranges, raising the narrow distribution rate from the original 76% to 86%. Retested cloud point and hydroxyl value fluctuations were maintained within client tolerance ranges, with a CNAS-accredited third party issuing full English COA test reports.
1. Rectification of Delamination & Floc Precipitation: 0.32% EDTA disodium chelating agent was added to the original formulation to shield trace metal ions in alkali liquor and inhibit salting-out reactions. A 0.4% short-chain modified isoamyl alcohol solubilizer was incorporated to balance overall HLB values, strengthening micelle stability under strong alkali conditions and eliminating low-temperature floc precipitation.
2. Rectification of Excessive Spraying Foam: The original organosilicon defoamer dosage was increased by 0.18 parts, compounded with trace polyether foam-suppressing components to counteract foam stabilization caused by short-chain raw material impurities while retaining high-temperature spray stability. Foam height was consistently controlled below 72mm, meeting internal low-foam standards.
3. Optimization for Degreasing & Water Stain Elimination: 0.7% narrow-distribution C10 isoalcohol ether blends were added in small quantities to reinforce system wetting and penetrating capacity, offsetting degreasing deficiencies caused by carbon chain disparities in domestic raw materials. Workpiece oil stripping efficiency recovered to 98.3% with no residual watermarks post drying.
1. Feeding Temperature Adjustment: Original uniform ambient-temperature (22℃) feeding was revised to preheat isotridecyl alcohol ether to 32℃ for slow addition, accelerating dispersion and dissolution of low-temperature raw materials to prevent localized high-concentration surfactant agglomeration. Strong alkali components were cooled to 28℃ for dropwise addition to control neutralization exothermic rates and reduce local high-temperature emulsion breakdown risks.
2. Agitation Equipment Parameter Modification: Reactor stirring speed was reduced from the original 115r/min to 82r/min, with low-speed mixed holding time extended by 45 minutes to reduce excessive foam generated by high shear, improving system uniformity and mitigating long-term storage delamination risks.
3. Raw Material Warehouse Storage Standardization: Custom raw materials were stored in sealed constant-temperature tanks maintained at 23℃, with opened containers required to be consumed within 15 days to isolate moisture absorption from ambient air. HiSiaddi compiled bilingual English-Dutch standardized production SOPs and delivered 2 days of hands-on training for workshop operators and quality control personnel on-site.
1. Laboratory Testing: Multiple rounds of lab and pilot trials combining refined raw materials and optimized formulations produced finished products stable without delamination after 90 days of ambient storage and free of precipitation after 30 days of 5℃ cold storage, with spray foam height of 70mm and aluminum component degreasing efficiency of 98.4%. All indicators passed third-party testing by SGS Belgium. The 7 tons of scrapped semi-finished inventory were reworked via auxiliary additive supplementation and converted into qualified products, recovering approximately 13,500 EUR in material losses.
2. Batch Production & Delivery: After rectification, the full 45-ton raw material batch was deployed across five sequential mass production runs. Twenty-two consecutive production shifts operated without delamination, foam overflow or substandard degreasing performance. Concentrated cleaning agents successfully passed full incoming audits at BMW component factories, enabling on-schedule bulk delivery.
3. Long-Term Strategic Cooperation Established: Localized procurement costs decreased by 28.5% versus original Clariant raw materials, and ocean transit lead times were shortened from 72 days to 32 days. The client terminated annual procurement orders with European manufacturers and signed a 260-ton annual long-term contract with HiSiaddi. A new special-grade degreaser for aerospace applications was commissioned for customized development and full technical support the following year.
1. Common Industry Pain Points: Domestic surfactant manufacturers conducting national standard mass production only monitor basic physicochemical indicators (hydroxyl value, cloud point) with loose control over high-end metrics including free alcohol content, hetero-carbon fractions and narrow EO distribution. Factories solely manufacture raw materials without downstream cleaning compound application R&D capacity. European mid-to-high-end precision cleaning clients rely long-term on imported high-purity narrow-distribution raw materials with highly fixed formulations and production line processes; direct substitution with domestic raw materials frequently triggers mass production scrapping and end-customer acceptance failures.
2. Procurement Characteristics of Mid-to-High-End Clients: Raw material quality directly determines supply chain access qualifications for automotive and aerospace component manufacturers. Finished product non-compliance risks order compensation and brand damage far exceeding raw material price differentials, making formulation stability and regulatory compliance top priorities with high tolerance for minor raw material premium pricing.
3. Core Value of HiSiaddi: A full-chain technical service covering upstream raw material refining and modification, downstream end-formula optimization and on-site production process adjustment at overseas factories, with dual technical reserves in surfactant synthesis and cleaning agent application. HiSiaddi bridges application barriers stemming from quality gaps between domestic and imported raw materials, delivering one-stop resolution of all technical challenges during localized substitution.
