Our partner is SWISS NATURE CARE, a high-end Swiss natural skincare group specializing in organic sensitive skin repair lines, maternal and infant-specific wash care products, and luxury fragrance shower gels. Its products cover premium European markets including Switzerland, Germany and Austria, and are supplied to top Swiss drugstores, organic beauty retail chains and SPA supply chains of five-star hotels. Adhering to core standards of natural origin, ultra-low irritation, high salt tolerance stability, full EU compliance and exclusive formula customization, the group imposes stringent requirements on the purity, impurity control, carbon chain distribution, concentration customization and low odor of hydroxypropyl sulfobetaine (CHSB). It purchases 80–100 tons of customized CHSB annually for its full range of premium wash care formulas.
Previously relying on local European suppliers, the client faced high costs and long lead times (45–60 days). This was their first attempt at Chinese sourcing. They put forward five major customized requirements, yet three contacted manufacturers all rejected the project citing "unattainable technical standards, high customization costs, and unwillingness to launch dedicated production lines", stalling the customization project. The client urgently entrusted HiSiaddi to fully manage customized development and implementation.
1. Customized carbon chain distribution: C12 accounting for 65% and C14 accounting for 35% (standard grades mostly feature unspecified mixed C12-14 carbon chains), tailored for low-irritation sensitive skin formulas;
2. Customized concentration: Standard grades generally have 30% solids content, while the client requires 35%±0.5% high-solids content to cut transportation costs and boost formula preparation efficiency;
3. Extreme impurity control: Unreacted amine ≤0.2%, sodium chloride ≤3% (standard grades allow unreacted amine ≤0.5% and sodium chloride ≤6%), colorless and odorless with no residual scent;
4. Customized salt tolerance stability: No turbidity or precipitation after 48 hours in 8% sodium chloride solution (standard grades only withstand 3%–5% salt concentration), compatible with high-salt efficacy formulas;
5. Compliance and traceability customization: EU REACH registration, ECOCERT/COSMOS organic certification and EWG green certification are mandatory; single-batch traceability reports, carbon chain distribution test reports and toxicological safety assessment reports must be provided.
1. High technical threshold: Precise carbon chain ratio control demands dedicated reaction kettles and accurate feeding regulation, a capability absent from ordinary manufacturers;
2. Conflict between cost and production capacity: High-solids formulation and low impurity levels require special purification processes, leading to high costs for dedicated production line operation, making manufacturers reluctant to take small-batch customization orders;
3. Strict testing standards: Gas chromatography testing for carbon chain distribution, special salt tolerance stability tests and sensory odor evaluation are required, equipment unavailable at most manufacturers;
4. Complex compliance documentation: Customized compliance statements and exclusive batch traceability documents are needed, while regular manufacturers only supply standard documents.
Partnering with leading domestic manufacturers specializing in high-end sulfobetaine production (Shandong Jiapeng and Jiangsu Langyou), HiSiaddi’s technical team set up a dedicated customization task force to break through barriers across five dimensions: formula design, process adjustment, purification optimization, customized testing and compliance matching. The full lab test, pilot production and mass production workflow was completed within 30 days.
We coordinated the factory to deploy a dedicated 5-ton reaction kettle, adopting a stepwise feeding process with precise temperature control (±0.5°C) to accurately regulate the raw material ratio of C12/C14 and guarantee C12 at 65% and C14 at 35%. Gas chromatography (GC) carbon chain distribution testing is conducted for every batch with exclusive test reports issued to ensure batch consistency with error margins ≤±1%.
Sulfonation and quaternization reaction parameters were optimized with extended reaction duration and reduced reaction temperature to minimize side reactions, limiting unreacted amine content to ≤0.2%. A two-stage membrane filtration and vacuum concentration process was adopted to remove sodium chloride impurities (≤3%) and precisely concentrate the product to 35%±0.5% solids content. The entire process operates under nitrogen protection to maintain a colorless, odorless product free of residual scent.
The proportion of hydroxypropyl groups in the molecular structure was adjusted to enhance salt resistance. Simulating the client’s high-salt formula environment, a 48-hour stability test in 8% sodium chloride solution was performed to confirm zero turbidity and precipitation, meeting the client’s requirements for extreme formulation conditions.
We extended REACH registration coverage and secured ECOCERT/COSMOS certification scope explicitly including the customized hydroxypropyl sulfobetaine grade (C12=65%/C14=35%, 35% solids content). Exclusive batch traceability reports were compiled to track the full supply chain from raw material procurement, production processes and test data to finished product delivery. EWG green certification (rating 1.0), toxicological safety assessment reports and biodegradation reports (OECD301F, 93% biodegradation rate within 28 days) were provided to satisfy the client’s natural safety standards.
· Lab test (7 days): 50kg laboratory trial with all indicators verified compliant. Samples were sent to the client’s Swiss laboratory for evaluation, demonstrating superior mildness, skin feel and stability compared to the client’s original European supplier material.
· Pilot production (10 days): 500kg trial production to validate process stability and consistent batch indicators.
· Mass production (13 days): 100-ton bulk production with HiSiaddi on-site production supervision and batch-by-batch testing to guarantee 100% compliance.
1. 100% of customized requirements fulfilled: All carbon chain ratio, solids content, impurity, salt tolerance stability and compliance documentation indicators met or exceeded client expectations;
2. Optimized costs and lead time: The customized product price was 22% lower than the client’s original European supplier, with lead time shortened to 30 days (versus the original 45–60 days);
3. Passed sample testing: The customized CHSB was trialed in sensitive skin cleansers and maternal-infant body washes, delivering dense mild foam, moisturizing skin feel, no turbidity at -5°C and stable compatibility with plant essential oils;
4. Signed bulk framework agreement: The client formally signed an annual 100-ton framework contract, appointing HiSiaddi as their exclusive supplier of customized CHSB;
5. Deepened long-term cooperation: The client further entrusted HiSiaddi to customize composite systems of hydroxypropyl betaine and APG for new product development.
The core pain point of this customization project was the conflict between exclusive high-end client demands and standardized mass production by Chinese manufacturers. Ordinary manufacturers declined customization orders due to technical limitations, high costs and low willingness to adapt. Relying on professional technical capabilities, access to premium manufacturing resources and a customized service mindset, HiSiaddi successfully overcame all bottlenecks:
1. Accurate interpretation of high-end demands: In-depth breakdown of the client’s five customized specifications to clarify non-standard, exclusive core requirements;
2. Integration of premium production resources: Collaboration with leading manufacturers capable of customization to coordinate dedicated equipment and processes;
3. Full-process technical oversight: End-to-end technical intervention covering formula, process, purification and testing to ensure all indicators meet standards;
4. Customized compliance documentation: Alignment with EU high-end market regulatory requirements and provision of exclusive traceability and certification documents.
For overseas mid-to-high-end wash care clients, China delivers not only price advantages for standard-grade CHSB but also technical and cost advantages for premium customized CHSB. HiSiaddi’s core value lies in bridging overseas high-end customization demands and China’s premium manufacturing capacity, forming a closed full-link loop of "demand → customization → implementation → compliance". This empowers clients to acquire exclusive premium raw materials while controlling costs and strengthening product competitiveness.
