Purchaser: ITALHEALTH Group, a premium health pharmaceutical enterprise headquartered in Milan, Italy. It has long supplied raw materials for clinical oral care, oral stomach-soothing softgels and high-end skincare serums across Italy. Its products are sold at high-end private clinics in Milan, Italian organic pharmacy chains and premium wellness supermarkets in Geneva, Switzerland. All product lines comply with EU E141 (ii) pigment specifications, EFSA food additive standards, USP Pharmacopoeia, REACH regulations and access requirements of Italy’s MINISTERO DELLA SALUTE. Its three core premium product lines are antibacterial medical mouthwash, stomach-soothing softgels and soothing skincare serums, targeting middle-class Europeans, medical aesthetic clients and high-net-worth gut health consumers. The group maintains a stable annual procurement volume of 16 tons of pharmaceutical-grade sodium copper chlorophyllin sourced locally in Europe.
Faced with continuous price hikes and extended shipping cycles for European raw materials, the client first purchased 5 tons of standard national standard sodium copper chlorophyllin from China. Upon arrival and production launch, five major mass production failures emerged en masse: flocculent precipitation in liquid mouthwash, screen clogging during softgel automatic filling, discoloration and fading of finished goods during storage, fluctuating heavy metal levels in raw materials, and stratification caused by chemical reactions with compound raw materials. Domestic suppliers only offered standardized off-the-shelf production with no capacity for formula compatibility R&D, powder modification or fine-tuning of production processes, unable to assist the client in formula optimization and resolve on-site production issues. Launch of new products stalled, and multiple automated production lines were forced to semi-shut down. The client fully entrusted HiSiaddi to deliver full-dimensional technical rectification covering raw material process improvement, end-product formula optimization, production process adjustment and storage & transportation control.
1.
Flocculent precipitation and turbidity in weakly acidic mouthwash formulation The client’s mouthwash formula contains chlorhexidine, citric acid and plant essential oils, with a finished product pH range of 5.2~5.6 (weakly acidic). Conventional national standard sodium copper chlorophyllin readily agglomerates and precipitates out of porphyrin rings under pH <6 environments. After standing for 12 hours, dark green flocculent sediment forms at the bottom of the liquid, failing light transmittance tests required by Italian drug administration and rendering entire batches of semi-finished products scrapped. Raw materials manufactured via fixed conventional saponification synthesis processes are only compatible with neutral formulations and lack stability in weak acid environments.

3.
Poor powder physical properties causing frequent screen blockage and excessive filling weight deviation in softgel automatic filling equipment The client operates German imported automatic softgel filling machines requiring uniform 200-mesh fine powder with repose angle 33°±2° and bulk density 0.54~0.58g/cm³. Off-the-shelf domestic products contain mixed particle sizes ranging from 80 to 180 mesh with heavy fine powder agglomeration and poor flowability. Screens clog after 2~3 hours of feeding, with capsule filling weight error exceeding 4% – far above the brand’s internal qualified standard of ±1.8%. Frequent equipment shutdowns for cleaning reduce production efficiency by 40%.

5.
Insufficient light stability of finished goods leading to discoloration and fading during storage and ocean shipping Sodium copper chlorophyllin is inherently light-sensitive, and the client’s finished products require a 24-month shelf life. Unmodified bare standard raw materials discolor from bright blue-green to dark brown after 45 days of normal temperature light-shielded storage, with partial fading of softgel contents. Color value attenuation exceeds 12% during high-temperature, high-humidity Mediterranean ocean shipping, failing quality standards for EU retail launch.
6.
7.
Fluctuating free copper and heavy metal levels triggering flocculation in compound skincare serums National standard raw materials allow free copper ≤25ppm, while the client’s premium skincare raw material internal control limit is ≤3ppm. Free copper levels in standard batches fluctuate between 8~22ppm. Raw materials with high copper content undergo complexation reactions with vitamin C and plant flavonoids in serums, resulting in colloidal flocculation and stratification that destroys the active system of skincare products.
8.
9.
Trace inherent off-odour in raw materials causing rework of oral softgels Conventional raw materials use low-cost forage grass and spinach for extraction, retaining burnt plant off-odours. When incorporated into stomach-soothing softgels, odours are released during high-temperature pelleting, resulting in abnormal taste in finished products that cannot enter premium pharmacy channels. Factories maintain fixed raw material supply chains and cannot switch to low-odour organic raw materials.
10.
1. HiSiaddi collaborated with source manufacturers to refine processes by adding trace food-grade cyclodextrin coating modification in the refining section, forming a protective outer film around sodium copper chlorophyllin molecules to boost stability in weak acid environments. Modified products fully dissolve without precipitation at pH ≥5.0.
2. Synchronously assist the client in fine-tuning mouthwash formulation via staged feeding: pre-dissolve sodium copper chlorophyllin with propylene glycol + warm water prior to adding acidic main ingredients to avoid instantaneous local over-acid agglomeration. Three small-batch formula trials yielded fully clear, precipitation-free solutions.
1. Revise raw material drying processes: replace traditional oven drying with low-temperature vacuum spray drying to form regular spherical particles, followed by closed airflow classification and sieving to precisely lock 200-mesh powder. Measured repose angle reaches 33.2° with bulk density 0.55g/cm³.
2. Client 24-hour continuous mass production machine testing recorded zero screen blockage during filling, with filling weight error stably controlled within ±1.3%, perfectly matching automatic softgel production lines.
1. Raw Material End: Add trace food-grade anti-light auxiliaries in post-production low-temperature homogenization for surface modification to boost pigment UV and heat resistance. Accelerated stability testing recorded color value attenuation <2.1% after 60 days.
2. Packaging Optimization: Adopt double-layer protection of inner light-shielded vacuum aluminum foil bags + black light-proof HDPE drums for raw materials. Simultaneously guide the client to package finished mouthwash in amber light-shielded bottles to resolve discoloration defects during ocean shipping and storage.
1. Adjust copper substitution reaction feed ratios and add a three-stage ion exchange rectification process to remove unreacted free copper ions and heavy metal impurities. Free copper levels in mass-produced finished products remain stably between 2.2~2.8ppm, with lead, arsenic and cadmium indicators all superior to EFSA EU limit standards.
2. Client skincare serum compatibility testing showed no flocculation or stratification after 90 days of mixing with vitamin C and plant extracts, meeting formulation compatibility requirements.
1. Coordinate factories to switch extraction substrates to organically certified silkworm excrement and mulberry leaves sourced from Sichuan fixed bases for lower pesticide residues and impurities.
2. Add alcohol elution deodorization processes and vacuum negative pressure removal of small-molecule odour impurities to deliver odour-free finished raw materials with no off-odour release during high-temperature softgel pelleting, resolving taste defects in end products.
1. HiSiaddi sent five groups of optimized samples to the client’s R&D centre in Italy for full-dimensional verification covering mouthwash compatibility testing, softgel mass production machine trials, accelerated storage stability, skincare serum compounding and sensory odour assessment. All indicators met the internal control standards for the client’s mid-to-high-end product lines.
2. The original 5-ton order was re-produced under optimized new processes and split into three specialized grades: 2.7 tons acid-resistant modified grade for mouthwash, 1.5 tons specialized powder grade for softgels, 0.8 tons high-purity grade for skincare serums. Prior to delivery, SGS conducted full-item testing under EU E141 (ii) and Italian standards to issue English COA and compliance documents.
3. HiSiaddi supplied full supporting documents including REACH-SDS, CCPIT Free Sales Certificate with Italian consular authentication. Goods shipped from Shanghai Port to Naples Port cleared customs without detention, and raw materials were warehoused for production, enabling timely launch of the client’s three new product lines in Italian premium pharmacies and private clinics.
The client terminated procurement from European local manufacturers and signed an annual framework purchase contract for 16 tons, with quarterly batch orders for modified customized sodium copper chlorophyllin. Subsequent expansion into premium Spanish clinical channels entrusted HiSiaddi with advance raw material formula pre-optimization for all new product formulations, deepening sustained long-term cooperation.
Domestic pigment manufacturers prioritize standardized national standard mass production with fixed processes and lack supporting R&D for end-product formula compatibility, with limited familiarity with strict internal control indicators and multi-dose formulation characteristics of overseas mid-to-high-end brands spanning liquid mouthwash, softgel and skincare serum categories. Minor physical and chemical defects in raw materials can trigger full-line production shutdown and finished product scrapping. Supported by reserves of chemical raw material process technology and end-product formulation application expertise, HiSiaddi closed the full technical service loop covering raw material process improvement, powder customization, formula compatibility and packaging & storage optimization, resolving mass production pain points via professional technical capabilities and securing stable long-term repeat orders.
