Direct factory supply of pharmaceutical-grade active ingredients, cosmetic cosmetic intermediates, and advanced formulation functional additives.
To successfully formulate topical preparations containing Azelaic Acid, Clindamycin, and Tretinoin, formulation scientists must understand their complementary mechanism of action at the cellular and follicular level. Combining these three active pharmaceutical ingredients (APIs) eliminates treatment resistance and accelerates skin clearance.
A natural dicarboxylic acid that acts as a reversible inhibitor of 5-alpha-reductase, reducing follicular keratinization. It selectively targets hyperactive melanocytes through competitive inhibition of tyrosinase, making it indispensable for acne, melasma, and rosacea without causing hypopigmentation in normal tissue.
A semi-synthetic lincosamide antibiotic prodrug that binds to the 50S ribosomal subunit of Cutibacterium acnes (formerly Propionibacterium acnes). It suppresses bacterial protein synthesis and dramatically curtails free fatty acid production in follicular lipids.
A potent retinoic acid receptor (RAR) agonist (CAS 302-79-4). It normalizes desquamation of the follicular epithelium, prevents microcomedone formation, and accelerates cellular turnover, allowing Azelaic Acid and Clindamycin to penetrate deeper into lesion sites.
| Active Ingredient | CAS Number | Molecular Formula | Standard Assay (USP/EP) | Primary Clinical Function |
|---|---|---|---|---|
| Azelaic Acid | 123-99-9 | C9H16O4 | 98.0% – 102.0% | Comedolytic, Anti-tyrosinase, Anti-inflammatory |
| Clindamycin Phosphate | 24729-96-2 | C18H35ClN2O8PS | 97.5% – 102.0% | Bactericidal (Anti-C. acnes), Anti-cytokine |
| Tretinoin (Retinoic Acid) | 302-79-4 | C20H28O2 | 97.0% – 103.0% | RAR Agonist, Epithelial Desquamation, Collagen Synthesis |
Formulating Azelaic Acid, Clindamycin, and Tretinoin within a single stable topical vehicle poses significant physicochemical challenges. Azelaic Acid is sparingly soluble in water and oil, requiring precise micronization (D90 < 10 µm) or micro-emulsification. Tretinoin is exceptionally photosensitive and vulnerable to oxidative degradation. Clindamycin Phosphate requires an aqueous pH range of 5.5 to 6.5 for maximum stability.
At JIMPOCHEM, our process engineering team has established state-of-the-art technological pathways to overcome formulation incompatibilities:
The international demand for high-purity dermatological APIs has surged driven by expanding prescription access, telehealth dermatology platforms, and global OEM product innovation. Global pharmaceutical procurement officers face stringent quality demands, regulatory compliance checks, and volatile supply chain constraints.
Requires USP/EP grade Azelaic Acid and Clindamycin APIs with complete DMF documentation, low impurity profiles (individual unspecified impurities < 0.1%), and reliable batch-to-batch consistency for regulatory registration in US FDA and EU EMA markets.
Demands stabilized Azelaic Acid derivatives (e.g., Potassium Azeloyl Diglycinate) and customized cosmetic-grade raw materials that offer rapid skin absorption, zero crystal precipitation, and seamless cold-process emulsification.
Requires flexible batch sizing (from 1kg pilot quantities to 1000kg commercial lots), ultra-pure micronized powders, and comprehensive Certificate of Analysis (CoA) verifications for customized prescription formulas.
Leverages JIMPOCHEM's massive manufacturing throughput, bonded warehousing, and multi-country regulatory clearances to maintain continuous regional stocks without supply disruption.
Designated Chemical Service Provider | Quality Leads the Future
JIMPOCHEM CO., LTD was established in 2010 and is headquartered in the Chemical Industry Park of Jinan City, Shandong Province. The company covers an area of over 500 acres and is a professional chemical raw material manufacturer integrating research and development, production, sales, and technical services.
Our core focus is centered on high-end fine chemicals, active pharmaceutical ingredients, and cosmetic raw materials. We hold multiple certifications, including ISO quality management system and environmental management system standards, committing ourselves to delivering top-grade chemical products and end-to-end procurement solutions to global client networks.
Supply Chain & Intelligent Production Capacity: Leveraging over 16 years of domain experience, we maintain strategic raw material procurement channels alongside automated continuous production lines. Our Jinan production hub balances high-volume industrial output with flexible custom batch synthesis.
Rigorous Quality Control & Full Traceability: Every production batch undergoes comprehensive HPLC, GC, MS, and FT-IR testing. Our end-to-end digital traceability system allows downstream partners to inspect raw material sources, processing parameters, and analytical test data via unique lot numbers.
Green Chemistry & Environmental Stewardship: Aligning with global "Dual-Carbon" sustainability goals, our modern facility integrates closed-loop wastewater recovery, advanced catalytic oxidation for VOC gas treatment, and green bio-fermentation pathways.
Navigating global pharmaceutical regulatory frameworks requires meticulous documentation and rigorous audit readiness. JIMPOCHEM supports global purchasers with complete dossier packages compliant with international standards.
We provide full eCTD Module 3 regulatory dossiers, Drug Master Files (DMF), Certificates of Suitability (CEP), EU REACH registration documents, and complete ICH Q1A stability testing protocols (accelerated and long-term data).
Light-sensitive actives like Tretinoin are packaged under inert nitrogen gas in triple-laminated aluminum foil bags within light-proof fiber drums. Temperature-controlled cold chain logistics safeguard API integrity during transit.
Our R&D team provides specialized formulation assistance—from resolving solubility limitations and viscosity tuning to optimizing active skin absorption rates in client-specific base formulations.
Detailed technical clarity for procurement directors, regulatory specialists, and cosmetic formulation chemists.
We utilize high-energy fluid energy jet mills equipped with inline laser diffraction particle size analyzers (Malvern Mastersizer). Our standard micronized grade achieves D90 < 10 µm and D50 < 3 µm. This micro-fine distribution prevents gritty textures in topical creams and significantly enhances skin penetration without requiring aggressive chemical solubilizers.
Tretinoin is inherently sensitive to light, oxygen, and heat. We manufacture Tretinoin under yellow actinic lighting, purge the inner aluminum foil packaging with high-purity nitrogen (>99.99%), incorporate food-grade antioxidants where specified, and ship via temperature-monitored cold chain containers to ensure zero degradation during sea or air transit.
Direct procurement from JIMPOCHEM eliminates middleman markups while guaranteeing origin transparency. Our Jinan production center operates integrated fermentation and chemical synthesis lines, giving us strict control over impurity profiles (B-epimer and clindamycin B content well within USP limits) at highly competitive volume pricing.
Yes. In addition to high-purity individual APIs, our contract manufacturing (OEM/ODM) division develops customized active pre-mixes, lipid suspensions, or finished bulk creams and gels tailored to client specifications under cGMP compliant cleanroom conditions.
Every shipment includes a batch-specific Certificate of Analysis (CoA) featuring complete analytical testing data (Assay, Heavy Metals, Residual Solvents via GC-HS, Particle Size Distribution, Microorganism limits), Safety Data Sheet (SDS), Certificate of Origin (COO), and ISO audit compliance reports.
