It is a genuine mid-to-high-end medical beauty skincare brand with no low-end mass-market businesses. It specializes in clinic anti-aging serums, firming eye creams and post-procedure repair essences. Its products hold Swiss SCCS safety certification, EU EC1223 regulatory access qualification and ECOCERT natural skincare certification, supplying more than 220 private medical beauty clinics and high-end drugstore chains across Switzerland, France and Liechtenstein.
The brand previously purchased acetyl hexapeptide-8 raw materials from Spain’s Lipotec for years. Affected by rising European raw material prices and extended delivery cycles, it launched a customized non-standard domestic substitution plan in 2025. The annual customized procurement volume of acetyl hexapeptide-8 reached 7.8 tons, covering three differentiated customized specifications.
1. High-purity powdered acetyl hexapeptide-8 (purity ≥99.5%): Free amino acid impurities ≤0.15%, moisture content ＜0.3%, single heavy metal content ＜0.08ppm. Designed exclusively for high-concentration anti-aging serums with a 10% addition rate, free of exogenous bacteriostats and inorganic salt residues.
2. 5% plant-derived propylene glycol liquid hexapeptide: The solvent adopts non-GMO corn fermented propylene glycol. Conventional commercial products generally use petrochemical-based propylene glycol, which fails to meet the brand’s organic skincare marketing claims. The product shows no crystal precipitation after 30 days of refrigeration at -5℃.
3. 20% active hyaluronic acid compounded hexapeptide stock solution: Precise compounding of acetyl hexapeptide and ultra-low molecular weight hyaluronic acid. Clients can directly fill eye cream with the finished product, while original manufacturers have no mature mass production compounding process.
The client independently contacted 4 leading domestic peptide manufacturers, yet all their core production lines only mass-produce standard 20% petrochemical propylene glycol-based hexapeptide complying with national standards, with fixed synthesis and purification production lines lacking flexibility: ① Producing high-purity powder requires three additional column chromatography purification procedures. Shutting down production lines for technical transformation incurs high costs, so most manufacturers refuse to carry out dedicated renovations. ② Formulating products with plant-based propylene glycol requires full replacement of solvent feeding equipment. Small-batch customization yields slim profits, and manufacturers only promote their own petrochemical solvent spot goods. ③ Compounding hexapeptide with hyaluronic acid requires coordination between peptide synthesis and biological polysaccharide blending workshops. Most peptide enterprises lack supporting HA blending workshops and decline compound customization orders.
Multiple rounds of sample testing by the client yielded unqualified formulas, delaying the new product launch schedule. The client ultimately entrusted HiSiaddi to coordinate the full implementation of customization.
As a technology-based foreign trade service provider, HiSiaddi screens API manufacturers equipped with flexible peptide pilot production lines and supporting compound blending clean workshops. It connects factory R&D departments, third-party testing institutions and the client’s Swiss R&D laboratory to deliver lab-scale testing, pilot production, mass production and full compliance supporting services throughout the whole process.
1. Purification Process Barrier: Conventional commercial hexapeptide only undergoes single chromatography purification and cannot reach the 99.5% high-purity standard. Three rounds of chromatography drastically reduce production capacity and raise raw material loss, making mass manufacturers reluctant to adjust mature production lines.
2. Solvent Raw Material Barrier: Most domestic propylene glycol is petrochemical-based, while food-grade plant-fermented propylene glycol meeting relevant standards comes with high procurement costs. Formulating liquid products requires re-calibrating dissolution curves, and manufacturers lack mature proportion data for reference.
3. Compounding Process Barrier: Acetyl hexapeptide tends to hydrolyze slowly under weak acid conditions. Compounding with hyaluronic acid requires an accurate buffer system, yet most manufacturers lack research data on compound stability.
4. Compliance Document Barrier: Domestic manufacturers can only issue Chinese national standard COA test reports, lacking itemized impurity test reports and complete INCI raw material filing documents required for Swiss SCCS audits.
HiSiaddi screened two leading domestic peptide enterprises and eliminated manufacturers focusing solely on standardized mass spot goods. It finally settled on a high-tech biological enterprise with solid-phase synthesis flexible pilot workshops and Class 10,000 sterile compound blending workshops. A multi-stage customization agreement (lab test → pilot production → mass production) was signed based on a locked-price annual long-term order of 7.8 tons. Raw material losses incurred during lab testing were included in the long-term order cost, prompting the factory to carry out dedicated production line renovation.
1. Add three rounds of reverse silica gel column chromatography fractional purification at the end of the synthesis process to remove free amino acids and short peptide impurities.
2. Adopt vacuum low-temperature freeze-drying at ≤-45℃ to avoid peptide chain hydrolysis caused by high temperature, stably controlling moisture content within 0.28%. Third-party sample testing recorded a purity of 99.62% and free amino acid content of 0.12%, fully meeting the client’s internal control standards.
1. Fully replace petrochemical propylene glycol with European-certified corn fermented propylene glycol as the solvent.
2. Adopt gradient temperature-controlled stirring and dissolution with segmented heating to prevent oversaturation and precipitation of hexapeptide at local positions. Complete high-low temperature cycle stability testing with no crystallization or delamination at -5℃~45℃.
1. Build a citric acid-sodium citrate buffer system to lock the pH value at 5.2±0.1 and inhibit hexapeptide hydrolysis.
2. Conduct sterile compounding in Class 10,000 clean workshops with 0.22μm terminal ultrafiltration sterilization, no additional preservatives added, compatible with aseptic filling processes for eye cream.
1. Lab samples (30g each): Shipped to the Swiss laboratory via international courier for human irritation patch tests, accelerated stability tests and in vitro anti-wrinkle activity tests. The activity difference between the three products and the original Spanish raw materials was less than 3%.
2. Pilot batches (400kg each): The client carried out small-batch trial production, with the texture and anti-wrinkle efficacy of anti-aging serums and eye creams fully compliant.
3. Mass production scheduling: The total order of 7.8 tons was split into high-purity powder (2.2 tons), 5% plant solvent liquid (3.5 tons) and compound stock solution (2.1 tons), delivered in 5 batches on a monthly basis.
1. Issue bilingual Chinese-English COA reports in accordance with Swiss SCCS and EU cosmetic regulations, detailing full test data including monomer purity, short peptide impurities, heavy metals and residual solvents.
2. Compile new GHS English MSDS documents and assist the client with EU CosIng raw material notification and pre-filing of cosmetic raw materials in Switzerland.
3. Customize light-proof IBC totes and aluminum foil packaging marked with the standard INCI name Acetyl Hexapeptide-8 together with batch traceability QR codes.
The comprehensive procurement cost of customized domestic raw materials decreased by 30% compared with imported Spanish raw materials. The three anti-aging new products successfully passed Swiss drug regulatory filing and were launched across all sales channels. After the first year of cooperation, the client renewed an annual order of 9.2 tons and added customized demand for Palmitoyl Tripeptide-5.
Supported by this high-end customized Swiss order, standardized SOPs for customized production of three types of hexapeptide were established. The export premium of high-end customized grades reached 33%. Relying on complete compliance documents, the factory subsequently developed multiple European clinic skincare brands from France and Italy.
A complete customized service chain for acetyl hexapeptide-8 was built: solid-phase synthesis process optimization → purification customization → solvent modification → compound R&D → EU compliance support. HiSiaddi has continued to undertake foreign trade customization businesses for various cosmetic peptides thereafter.
The core production capacity of domestic peptide manufacturers is concentrated on low-cost general hexapeptide spot goods with petrochemical solvents, and they are reluctant to invest in technical renovations for purification and compounding. Mid-to-high-end European and American medical beauty skincare brands are restricted by strict Swiss and EU regulations, requiring exclusive customization in terms of raw material purity, solvent sources and compound formulas, which cannot be matched by general spot raw materials.
By balancing manufacturers’ technical renovation costs through annual long-term orders, HiSiaddi delivered customized indicators covering the full chain from synthesis source to terminal compounding, achieving a win-win situation for three parties: cost reduction for clients, product upgrading for manufacturers and business growth for service providers.
