candle fragrance oil

When sourcing fragrance oils, the Flash Point is critical; oils with a flash point above 200°F (93°C) are safer for gel candles and easier to ship. You must also verify the Scent Throw (both cold and hot), ensuring the oil performs well when the candle is unlit and while burning. Additionally, check the Specific Gravity and Refractive Index to ensure batch-to-batch consistency and purity.

Suppliers must provide an IFRA (International Fragrance Association) Certificate of Conformity, which specifies safe usage levels for different applications. A comprehensive SDS (Safety Data Sheet) is mandatory for customs and logistics. For specific markets, ensure compliance with REACH (EU) or California Proposition 65 (US) to avoid legal risks regarding hazardous substances.

Fragrance oils behave differently in Soy Wax, Paraffin, and Beeswax. You should request the Solubility Profile from the supplier. High-quality oils should have a Fragrance Load capacity of 6-10% without causing 'sweating' (oil leaching) on the candle surface. Always request 10ml-50ml samples to conduct burn tests with your specific wax blend before placing bulk orders.

Premium oils should be Phthalate-Free and Paraben-Free to appeal to health-conscious consumers. They must possess high thermal stability to prevent the scent from 'fading' or changing notes when exposed to the high heat of a candle flame. Ensure the oil is UV-inhibited or advise on stabilizers if the fragrance is prone to discoloring the wax when exposed to sunlight.

Fragrance oils are often classified as Class 3 Flammable Liquids or Class 9 Miscellaneous Dangerous Goods depending on their flash point. You must ensure the supplier uses UN-certified packaging (typically fluorinated HDPE bottles or lined aluminum canisters) to prevent leakage and evaporation. Failure to declare these as Dangerous Goods (DG) can lead to heavy fines or seizure by customs.

For large-scale procurement, use Made-in-China.com's Secured Trading Services to protect your payment until the goods pass inspection. Negotiate a tiered pricing structure where the unit price drops by 15-20% for orders exceeding 100kg. Request a Certificate of Analysis (COA) for every batch to ensure the quality matches the initial sample provided.

Due to the liquid nature and chemical sensitivity, Sea Freight is the most economical for bulk (200kg+), but ensure the containers are stored away from heat sources. For smaller batches, use specialized chemical couriers (like FedEx/DHL with DG accounts). Always confirm the Incoterms; FOB (Free On Board) is recommended so you can maintain control over the specialized logistics provider.

Prioritize suppliers on Made-in-China.com that have the 'Audited Supplier' badge. Check if they have ISO 22716 (GMP for Cosmetics) or ISO 9001 certifications. A reliable manufacturer should offer custom scent formulation (OEM/ODM) and provide a Gas Chromatography-Mass Spectrometry (GC-MS) report upon request to prove the chemical composition.
