View Product DetailsIn modern cosmeceutical formulations, pairing Azelaic Acid (dicarboxylic acid) with Vitamin C (L-ascorbic acid and its lipophilic/hydrophilic derivatives) represents one of the most effective multi-target strategies for treating post-inflammatory hyperpigmentation (PIH), rosacea, acne vulgaris, and photoaging. As global cosmetic brands transition toward evidence-based functional skincare, Chinese raw material manufacturers have engineered precise molecular derivative grades and co-crystallization techniques to overcome historical formulation incompatibility.
Azelaic acid acts as a competitive, reversible inhibitor of tyrosinase specifically within hyperactive abnormal melanocytes, sparing normal pigmentation. When combined with Vitamin C—which reduces dopaquinone back to DOPA and scavenges reactive oxygen species (ROS)—melanogenesis is suppressed across two distinct catalytic steps, producing faster clinical clearance of melasma.
Azelaic acid downregulates inflammatory cytokine expression (IL-1β, IL-6, and TNF-α) by suppressing the NF-κB pathway while reducing kallikrein-5 and cathelicidin LL-37 in rosacea patients. Vitamin C neutralizes lipid peroxidation free radicals induced by cutaneous inflammation, preserving extracellular matrix integrity.
L-Ascorbic acid requires an acidic environment (pH < 3.5) for epidermal penetration, whereas Azelaic Acid functions optimally between pH 4.0 and 5.5. Advanced Chinese manufacturers resolve this stability paradox using water-soluble derivatives like Ascorbyl Glucoside (AA2G, CAS 129499-78-1) or lipophilic forms like Ascorbyl Tetraisopalmitate (CAS 183476-82-6).
| Active Ingredient / Derivative | CAS Number | Optimal pH Range | Solubility Profile | Synergy Profile with Azelaic Acid |
|---|---|---|---|---|
| Azelaic Acid (Micronized) | 123-99-9 | 4.0 - 5.5 | Slightly soluble in water; Soluble in glycols | Base active: 10-20% formulation target for sebum control & anti-erythema. |
| Ascorbyl Glucoside (AA2G) | 129499-78-1 | 5.0 - 7.0 | Highly Water Soluble | Perfect pH alignment with Azelaic Acid; slow enzymatic conversion to Vitamin C. |
| Ascorbyl Tetraisopalmitate | 183476-82-6 | 4.0 - 6.0 | Lipid / Oil Soluble | Enables anhydrous or dual-phase emulsions; high percutaneous absorption. |
| Glycolic Acid | 79-14-1 | 3.5 - 4.5 | Water Soluble | Keratolytic enhancer; accelerates azelaic acid epidermal penetration. |
| Sodium Phytate | 14306-25-3 | 3.0 - 9.0 | Water Soluble | Natural chelator; prevents trace metal ion oxidation of Vitamin C derivatives. |
China has emerged as the premier global hub for high-purity cosmetic actives, fine chemicals, and specialty ingredients. Leading manufacturers like JIMPOCHEM CO., LTD leverage integrated industrial clusters, advanced green chemistry process loops, and robust quality management systems to supply Fortune 500 cosmetic conglomerates globally.
Headquartered in the Chemical Industry Park of Jinan City, Shandong Province, JIMPOCHEM spans over 500 acres. Direct pipeline access to key intermediate feedstocks lowers logistics costs, allowing high-volume output of ultra-pure Azelaic Acid and Vitamin C derivatives with uncompromised price competitiveness.
Operating under ISO 9001 quality management and ISO 14001 environmental frameworks, every production batch undergoes full-item testing via HPLC, GC-MS, and ICP-MS. Our digital traceability system connects batch numbers directly to raw material origin, process logs, and third-party analytical reports.
In response to global carbon-reduction directives, JIMPOCHEM employs catalytic green oxidation for azelaic synthesis, closed-loop solvent recycling, and advanced VOC/wastewater neutralization, enabling eco-certifiable raw material supply for global clean beauty formulations.
The global demand for co-formulated Azelaic Acid + Vitamin C products is experiencing rapid growth, driven by consumer preference for multifunctional, dermatologically backed skincare routines. Global brands face distinct technical and supply chain requirements during vendor evaluation:
To eliminate hydrolysis of sensitive actives, brands are shifting toward anhydrous suspension gels (e.g., Azelaic Acid in silicone/ester bases paired with oil-soluble Ascorbyl Tetraisopalmitate) or polymeric microencapsulation. Chinese suppliers provide custom micronized powder grades (particle size D90 < 10 μm) designed for uniform suspension without gritty texture.
Cross-border procurement requires comprehensive dossier support. Leading Chinese manufacturers provide REACH registration, US FDA VCRP filling support, EU CPNP compliance, Halal, Kosher, and non-GMO certifications to streamline regulatory submission across North America, Europe, and Southeast Asia.
Global cosmetic companies require flexible batch sizes (MOQs starting from 25kg drums to multi-ton bulk shipments), custom blend pre-mixes, and reliable lead times to mitigate supply chain disruptions in international shipping lanes.
JIMPOCHEM operates across multiple chemical sectors, integrating R&D, continuous flow production, and global technical service. Our product ecosystem extends beyond cosmetic actives into pharmaceutical excipients, organic intermediates, and high-performance industrial additives.

Formulating stable, highly bioavailable products containing both Azelaic Acid and Vitamin C derivatives requires strategic addition of functional co-ingredients. Chinese manufacturers supply specialized supporting materials that solve key technical challenges in product development:
Azelaic Acid exhibits poor water solubility. Utilizing premium ester solvents such as Isopropyl Myristate (CAS 110-27-0) or binder systems with Magnesium Myristate (CAS 4086-70-8) ensures uniform dispersion of micronized azelaic particles, preventing recrystallization and gritty sensory profiles.
Trace metal ions (Fe³⁺, Cu²⁺) accelerate the degradation of Vitamin C derivatives. Incorporating natural chelating agents like Sodium Phytate (CAS 14306-25-3) effectively sequesters transition metal cations, extending shelf life and preventing yellow discoloration in clear serum gels.
To reduce cutaneous stinging or dryness associated with high-dose Azelaic Acid (10-15%), formulators integrate PPG-20 Methyl Glucose Ether (CAS 61849-72-7) as a non-comedogenic humectant and sensory modifier, improving spreadability and moisture retention.
Technical answers to common formulation, purchasing, and regulatory inquiries regarding Azelaic Acid and Vitamin C derivatives sourced from Chinese chemical suppliers.
While possible, it presents formulation stability challenges. L-Ascorbic acid requires a pH < 3.5 for stability, whereas Azelaic Acid works best at pH 4.0-5.5. At pH < 3.5, Azelaic Acid can precipitate out of solution. Chinese manufacturers recommend using Ascorbyl Glucoside (AA2G, CAS 129499-78-1) or oil-soluble Ascorbyl Tetraisopalmitate (CAS 183476-82-6), which remain stable at pH 4.5-5.5, enabling a harmonious dual-active water-based or emulsion system.
Standard commercial grades have a particle size of D90 < 45 μm. However, for leave-on serums, lotions, and suspension gels, JIMPOCHEM offers specialized micronized Azelaic Acid with D90 < 10 μm. This ultra-fine specification enhances skin absorption, improves suspension stability, and eliminates gritty tactile feel in finished cosmetic products.
Vitamin C derivatives and active powders are sensitive to light, oxygen, and humidity. Export shipments are packaged in heavy-duty aluminum foil barrier bags flushed with dry nitrogen gas, enclosed within light-blocking fiber drums. Additionally, free samples and commercial shipments include Certificate of Analysis (COA) documentation verifying purity (HPLC > 99.5%) and low heavy metal limits (< 5 ppm).
For standard cosmetic raw materials like Azelaic Acid, Ascorbyl Glucoside, and Sodium Phytate, the standard MOQ is 25 kg per drum. Custom micronization, liquid pre-mixes, or specialized derivatives have MOQs ranging from 100 kg to 1 metric ton. Standard air-freight sample delivery is 5-7 business days, while ocean bulk container shipments typically take 2-4 weeks depending on destination ports in Europe, North America, or LATAM.
