Private Mask OEM & ODM Global Contract Manufacturing

Private intimate masks are formulated for non-keratinized or semi-keratinized epithelial tissue characterized by significantly higher mucosal permeability and vulnerability to microbial imbalance. While facial masks average pH 5.5 to 6.5, intimate masks must maintain a physiological acidic buffer between pH 3.8 and 4.5 using stabilized L-lactic acid and citrate buffers. Furthermore, intimate formulas omit standard facial film formers, penetration enhancers, synthetic perfumes, and essential oils that trigger burning or contact dermatitis in the vulvar or perineal zones.

For mature stock formulations utilizing existing die-cut tooling and standard foil sachet dimensions, private labeling typically starts at an agile MOQ of 3,000 to 5,000 units. For fully bespoke ODM developments involving custom ergonomic shapes, specialized bio-cellulose fermentation runs, proprietary active ingredient sourcing, or custom holographic foil printing, MOQs typically begin at 10,000 to 20,000 units depending on substrate availability and packaging component runs.

Yes. Our internal regulatory department operates in accordance with GMPC and ISO 22716 cosmetic Good Manufacturing Practices. For European Union distribution, we compile the complete Product Information File (PIF), oversee 3-month accelerated stability and microbial challenge testing (ISO 11930), and prepare Cosmetic Product Safety Reports (CPSR Part A & B). For the United States, we verify ingredient safety dossiers under MoCRA, manage FDA cosmetic facility listings, and structure compliant labeling text.

Prior to commercial release, every production master batch undergoes a rigorous 4-tier verification protocol: (1) Physicochemical evaluation (viscosity, specific gravity, refractive index, and precise pH monitoring across thermal intervals); (2) Accelerated thermal stability testing at 4°C, 25°C, 40°C, and 48°C for 90 days alongside freeze-thaw cyclics (-10°C to +40°C); (3) Antimicrobial preservative efficacy challenge tests targeting Candida albicans, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa; and (4) Third-party dermatological HRIPT (Human Repeat Insult Patch Test) verifying non-sensitization.

Our standard OEM/ODM timeline follows a structured five-stage pipeline: Lab benchmark sample development and dispatch requires 3 to 5 business days; packaging proofing and custom die-line artwork confirmation takes 5 to 7 days; mass production of bulk serum, automated cleanroom filling, ultrasonic pouch sealing, and secondary box packing is executed within 20 to 25 calendar days; pre-shipment quality inspection and COA issuance takes 2 days. Global freight dispatch via sea (18–30 days), air cargo (4–7 days), or express rail to Europe is managed through our comprehensive logistics network.
