Primer Supplier & Manufacturer

Under an OEM (Original Equipment Manufacturer) framework, brand partners provide their proprietary formula specifications or benchmark requirements, and Aodai handles precise synthesis, pilot scale-up, emulsification, and contract filling using either customer-supplied or factory-sourced primary packaging. Under an ODM (Original Design Manufacturer) framework, Aodai provides turnkey service: selecting a validated base formula from our 5,000+ mature portfolio, engineering custom biological active additions, designing proprietary packaging moulds, executing graphic artwork, testing full package-formula compatibility, and managing export regulatory documentation.

Formulation pilling occurs when high-molecular weight linear silicones or incompatibly charged carbomer networks form an unyielding film that rolls off upon the friction of applying a subsequent aqueous emulsion. Our formulation scientists solve this through dual-phase cross-linking technology and balanced HLB (Hydrophilic-Lipophilic Balance) coupling agents. We incorporate volatile hemisqualane or cyclopentasiloxane alternatives that evaporate steadily, leaving an ultra-thin, flexible elastomeric mesh with hydrophilic anchor points that physically and chemically lock onto water-based foundations.

Yes. To meet European Union Annex XVII restrictions on octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclohexasiloxane (D6), our R&D center developed our patented Bio-Slip Matrix. This platform substitutes cyclic siloxanes with biodegradable coconut-derived alkanes, isopentydiol, and triheptanoin, achieving identical volatility profiles, light-diffusing velvet dry-down, and silky sensorial slip while maintaining 100% clean-beauty regulatory compliance across all EU member states.

Every candidate formulation must complete a rigorous 12-week stability regime before production release. Testing encompasses: constant thermal testing at 4°C, 25°C, 40°C, and 48°C with 75% relative humidity; 5 freeze-thaw cycles (-20°C to +40°C over 48-hour periods); mechanical centrifugation at 4,000 RPM for 30 minutes to check phase coalescence; and xenon-arc accelerated UV light exposure to verify color and fragrance stability. Formulas are also tested inside their intended production packaging to observe vacuum-pump pull force and seal integrity.

For mature, in-library formulas using our standardized stock packaging components, initial trial orders start at 2,000 to 3,000 units. For fully customized formulas requiring new active sourcing and custom tooling, our standard MOQ is 5,000 to 10,000 units per SKU. Once lab pre-production counter-samples are formally signed off, bulk automated synthesis and filling typically conclude within 25 to 35 business days, followed immediately by container consolidation and export clearance at Shenzhen, Guangzhou, or Hong Kong maritime ports.

Yes. Aodai provides complete technical and regulatory export dossiers. For the United States market, we supply full facility registration credentials and formula ingredient listings compliant with the Modernization of Cosmetics Regulation Act (MoCRA). For the European Union and UK markets, we supply standardized Cosmetic Product Safety Reports (CPSR Part A & B), INCI ingredient breakdowns, stability documentation, heavy metal and challenge test analytics, and allergens statements ready for your designated Responsible Person (RP) to register directly on the Cosmetic Products Notification Portal (CPNP).

Our 70,000 m² Qingyuan base utilizes automated PLC-controlled vacuum emulsification reactors. Raw material dispensing is governed by barcoded scanning stations linked directly to our central ERP system to eliminate operator measurement errors. Temperature, homogenizer shear speed, vacuum levels, and cooling curves are automated and logged in real time. Prior to tank discharge, QC specialists take multi-point samples to evaluate delta-E color variance under multiple light booths (D65, TL84, A) and confirm target viscosity curves on Brookfield viscometers against retaining control samples.

Yes. We regularly develop multi-functional hybrid sunscreen primers featuring SPF15 up to SPF50+ with high PA protection ratings. We formulate both 100% mineral-based systems utilizing micronized and non-nano zinc oxide/titanium dioxide coated with triethoxycaprylylsilane, as well as chemical filter combinations (such as diethylamino hydroxybenzoyl hexyl benzoate, bis-ethylhexyloxyphenol methoxyphenyl triazine, and ethylhexyl triazone) tailored to the specific sunscreen regulatory monograph of your destination market.
