Naturaclean is a leading European R&D enterprise of mid-to-high-end natural concentrated cleaning raw materials, specializing in organically certified dishwashing liquids and low-irritation industrial cleaners for maternal and infant use. Its products are supplied to high-end supermarkets and daily chemical OEM manufacturers across Switzerland, Germany and Austria. All product lines comply with EU REACH, ECOCERT natural organic raw material certification, EU biodegradation standards and CLP chemical regulations. Previously, the enterprise sourced its core emulsifying and penetrating additives from customized TO-series isotridecyl alcohol ethoxylate manufactured by BASF Germany.
However, surging natural gas costs in Europe, a minimum order quantity of 35 tons for BASF’s customized products, lead times exceeding 60 days, and an annual raw material price hike of 22% prompted the client to launch localized domestic substitution. The client entrusted HiSiaddi to source manufacturers in China capable of customized production, with an annual customized procurement volume of 180 tons.
1. Customized molecular structure: Isotridecyl alcohol feedstock limited to highly branched carbon chains (C13 branching degree ≥92%); the molar addition amount of ethylene oxide (EO) precisely controlled at 8.3mol (mass-produced commercial grades only feature integer EO additions of 7/8/9mol without non-standard 8.3mol options); narrow EO distribution controlled with a narrow distribution rate ≥85%.
2. Physicochemical indicators: Hydroxyl value 96±1.5mgKOH/g; cloud point of 1% aqueous solution 78±2℃; viscosity 1220~1280mPa·s at 25℃; moisture ≤0.03%; free alcohol ≤0.4%; pH value 5.3~6.2; APEO, formaldehyde by-products and heavy metal impurities prohibited.
3. Application performance: Low foaming (foam height ＜15mm under 500ppm hard water environment); strong alkali resistance (no delamination under pH 13 working conditions); silicone oil emulsification rate ≥98%; required dosage reduced by 22% compared with standard 1309 under identical formulations.
4. Environmental compliance: All components fully registered under REACH; no substances from the 253 SVHC candidate list detected; biodegradation rate ≥93% under OECD301B 28-day testing standard; compatible with EU organic daily chemical certification.
The client independently contacted three leading domestic isotridecyl alcohol ether manufacturers: Wuhan Huangma Technology, Jihechang and Haixing Chemical, yet none could deliver the customized product. Core pain points are summarized as follows:
1. Manufacturers only mass-produce standard grades and refuse non-standard customization: The three factories mainly produce conventional grades with integer EO additions (1306, 1307, 1308, 1309). Switching large continuous production lines for non-standard 8.3mol EO requires equipment shutdown, reactor cleaning and catalyst ratio adjustment, incurring high single-batch debugging costs. Factories declined precise EO customization citing low non-standard order volumes and complicated technical adjustments, only offering off-the-shelf 1308 or 1309 alternatives.
2. Substandard feedstock quality: Conventional domestic products adopt general petroleum-based isotridecyl alcohol with branching degrees ranging from 82% to 86%, failing to meet the client’s ≥92% high-branching feedstock threshold. Domestic factories lack stable import channels for high-purity imported isotridecyl alcohol when attempting to upgrade raw materials.
3. Unstable batch consistency: Mass-produced standard grades feature broad EO distribution with cloud point fluctuations of ±5℃ between batches, failing to meet the client’s narrow tolerance of ±2℃. Small-batch trial samples caused delamination of concentrated cleaning agents at low temperatures and emulsion breakdown after 30 days of storage upon compounding.
4. Incomplete compliance support: Domestic manufacturers can only provide national standard COA certificates, unable to issue full English REACH dossiers, OECD biodegradation test reports and supporting ECOCERT raw material qualification documents required by EU regulations, preventing the client from filing raw material records in the EU registration system.
The Swiss client’s R&D director possessed profound formulation expertise but lacked familiarity with domestic surfactant batch reactor processes, raw material import channels and factory production scheduling rules. Three rounds of trial samples all failed testing, putting the customization project on hold. Without successful domestic substitution, the client would be forced to continue purchasing costly BASF raw materials.
HiSiaddi set up a special task force consisting of chemical customization engineers, raw material procurement specialists and compliance officers, partnering with fine chemical factories equipped with flexible batch reactor customization capacity. The team delivered a closed-loop customized solution covering raw material selection, process debugging, sample optimization, pilot mass production and compliance certification.

Targeted Matching of Upstream Raw Materials to Secure High-Purity Isotridecyl Alcohol Leveraging its imported chemical raw material resources, HiSiaddi coordinated with ExxonMobil’s Asia-Pacific agent to bulk import high-branching C13 isotridecyl alcohol with a branching degree of 93.1%, locking in pricing and stock in advance. Raw materials were shipped directly to production facilities to eliminate markup from intermediate distributors, resolving manufacturers’ inability to source premium feedstock.

Custom Synthetic Process Development for Precise Non-Standard 8.3mol EO Addition (1) A dedicated 5m³ batch reactor was deployed to avoid halting mass production lines. Debugging proceeded in three phases: a special potassium-calcium composite catalyst (distinct from conventional KOH catalysts) was adopted, with ethylene oxide added dropwise in segmented precise doses. Real-time online hydroxyl value monitoring was implemented with sampling and retesting every 2 hours to strictly control the average EO addition at 8.3mol. (2) Post-treatment processes were optimized via vacuum negative pressure stripping to remove residual free ethylene oxide and free alcohol, limiting free alcohol content to 0.32% and moisture to 0.027%, eliminating excessive by-product levels. (3) Three rounds of trials were conducted: 30kg lab-scale samples, 300kg pilot batches and 3-ton pre-production batches. Each batch was sent to a CNAS-accredited third-party laboratory for testing, with cloud points consistently maintained between 77℃ and 79℃, fully complying with tolerance requirements.

Joint Formulation Debugging to Match the Client’s End-User Production Conditions HiSiaddi shipped trial samples of each production stage to the Swiss client’s laboratory and collaborated with the client’s daily chemical engineers on compounding tests:
6.
· Round 1 lab samples recorded foam height of 21mm (exceeding standard); HiSiaddi fine-tuned molecular capping additives to optimize hydrophobic end structures.
· Round 2 pilot samples achieved foam height of 14mm and silicone oil emulsification rate of 98.6%, with no delamination after 72 hours of standing under pH 13 strong alkali conditions and uniform emulsion without precipitation after 30 days of cold storage at -5℃. Performance fully satisfied formulation requirements, matching BASF’s original samples while enabling lower dosage.
1. Delivery of Complete EU Compliance Documents to Meet Mid-to-High-End Client Access Qualifications (1) HiSiaddi coordinated with EU compliance laboratories to conduct 28-day biodegradability testing per OECD standards and issue English test reports recording a biodegradation rate of 93.7%. (2) Compiled raw material monomer REACH registration numbers, product component dossiers, completed full SVHC screening, and prepared bilingual (English/French) CLP-compliant SDS and GHS labeling documents. (3) Organized a full set of qualification files to assist the client with EU organic daily chemical raw material filing and satisfy traceability audits for ECOCERT certification.
1. Initial Order Delivery: After successful pre-production trials, the first customized mass production batch of 25 tons was packed in food-grade IBC totes and shipped from Shanghai Port to Hamburg. After mass production launch at the Swiss client’s facility, finished concentrated maternal and infant cleaners passed third-party supermarket inspections in one go, with superior end-product stability compared to original BASF raw materials. Raw material procurement costs dropped by 31% versus imported BASF supplies, and ocean transit lead time was shortened to 28 days.
2. Annual Framework Agreement Signing: Naturaclean signed a 180-ton annual customized framework order with HiSiaddi, split into six scheduled batches based on demand. HiSiaddi maintained dedicated safety stock of raw materials and flexibly adjusted single-batch production volumes aligned with the client’s seasonal order fluctuations.
3. Long-Term Supporting Services: HiSiaddi conducted full-indicator pre-inspection of all batches prior to delivery and pre-reviewed compliance documents. Annual SVHC retesting was performed in line with REACH regulation updates. Two additional gradient EO-modified customized grades were subsequently developed for the client, sustaining deep collaborative ties.
