OEM Nivea Deodorant Factory & Contract Manufacturing Hub

Yes. The iconic sensory profile of leading Nivea roll-on formulations is built upon a fine-tuned Oil-in-Water (O/W) emulsion matrix stabilized by steareth-2 and steareth-21 ether surfactants, paired with volatile cyclomethicones or lightweight isohexadecane emollients. Our Huadu and Qingyuan laboratories have mapped the viscosity profile (1,800 to 2,400 mPa·s at 25°C) to ensure ideal rolling glide, instantaneous shear-thinning upon dermal application, and a non-tacky finish that dries in under 45 seconds.

Under international regulatory frameworks (especially US FDA and China NMPA), an Antiperspirant contains aluminum or zirconium salts that plug sweat ducts to reduce actual sweat flow; in the US, it is classified as an OTC drug requiring an NDC (National Drug Code) and strict monograph compliance. A Deodorant simply prevents or masks odor via antibacterial agents or fragrance and is regulated as a general cosmetic. Our factory is equipped and certified to manufacture both formats, supplying full drug master files (DMF) or cosmetic safety dossiers accordingly.

Ocean container transport exposes products to severe ambient pressure fluctuations and thermal expansions inside ship holds. We eliminate roll-on leakage through: (1) High-precision injection tooling with ball diameter tolerances held to ±0.005mm; (2) An internal sealing bead on the cap that presses the ball firmly against the housing rim when torqued; (3) Automated in-line capping torque testing; and (4) 100% pneumatic vacuum chamber leak checks at 0.5 bar during quality release.

For standard formulations utilizing in-stock packaging components (bottles, roll-on balls, caps), our entry MOQ begins at 5,000 to 10,000 units per SKU. For custom packaging colors, custom-tooled plastic bottles, or specialized aluminum aerosol lithographic printing, our production line MOQs start at 20,000 to 30,000 units due to automated batch emulsification minimums and industrial printing run constraints.

Yes. Baking soda (sodium bicarbonate) can irritate axillary skin due to its high pH (around 8.5–9.0). We manufacture sensitive-skin natural deodorants utilizing micronized magnesium hydroxide, zinc ricinoleate, and bamboo-derived silica powders. This achieves physiological pH compatibility (pH 5.5 to 6.2), absorbing moisture and neutralizing odor without disrupting the skin's protective acid mantle.

Every shipment is accompanied by a comprehensive Certificate of Analysis (COA) containing: pH levels, specific gravity, kinematic viscosity, active ingredient assay (ACH/AZAG percentage verified via titration or ICP-OES), heavy metal testing (lead, arsenic, mercury, cadmium below 1 ppm), and total aerobic microbial counts (<10 CFU/g). Additional clinical trials (dermatological patch testing, 48-hour anti-odor sniffer panel assessments) can be arranged via third-party testing partners like SGS or Intertek.

Aluminum salts have an acidic pH (approx. 3.0 to 4.5 in aqueous solution), which causes unstable fragrance oils to oxidize, discolor, or split from emulsion matrices. We use specially screened, acid-tolerant fragrance formulations created in partnership with international fragrance houses (Givaudan, Firmenich, IFF) and incorporate beta-cyclodextrin microencapsulation. These capsules rupture upon friction and contact with body heat, releasing fresh fragrance notes precisely when the consumer begins to perspire.

Yes. Aerosol antiperspirants contain liquefied petroleum gases (LPG) and are classified as UN 1950 Class 2.1 Dangerous Goods. Guangdong Aodai operates dedicated explosive-rated gassing lines and maintains full Chinese Dangerous Goods export packaging certifications. We coordinate all maritime hazard bookings, MSDS declarations, container placarding, and customs documentation directly through major shipping ports in Guangzhou and Shenzhen.
