For any serious candle maker, understanding the specifications of the fragrance oils you use is as crucial as selecting the right wax or wick. These details, often provided by a supplier of fragrance oil, dictate performance, safety, and scent quality. When you decide to buy fragrance oil, arming yourself with this knowledge ensures you make informed purchasing decisions.

Key Specifications to Look For:

1. Product Name and Scent Profile: This is the most basic identifier, like 'Wood Sage & Sea Salt Fragrance Oil'. Understand the described scent notes (e.g., floral, woody, fresh) to ensure it aligns with your product concept.

2. Grade: Fragrance oils can come in various grades. For applications like candle making, 'Perfume Grade' or 'Candle Grade' oils are typically recommended. These are formulated for optimal performance in wax and provide a good scent throw. Ensure your chosen aroma chemical supplier clarifies the grade.

3. CAS Number (Chemical Abstracts Service): While many fragrance oils are complex mixtures and may not have a single CAS number for the blend, individual aroma chemical components within the blend will have them. Some suppliers may list a CAS number for the blend itself if it's a standardized formulation. Understanding CAS numbers is more critical when sourcing individual aroma chemicals rather than pre-mixed fragrance oils.

4. Recommended Usage/Dosage: Suppliers often provide a recommended dosage range (e.g., 3-10%) for specific applications like candle making. Adhering to these guidelines ensures optimal scent throw without negatively impacting the wax or flame. When you purchase fragrance oil, check for this information.

5. Safety Data Sheets (SDS/MSDS): These documents are vital. They detail the chemical composition, potential hazards, handling precautions, and first-aid measures. Reputable manufacturers, including those in China, will readily provide these for their products.

6. Packaging and Quantity: Fragrance oils are typically sold in various sizes, from small sample bottles (10-100ml) to larger drums (25kg). This information is important for planning your inventory and understanding pricing tiers.

Where to Source: When you buy fragrance oil, consider manufacturers and suppliers who are transparent about their product specifications. Companies that specialize in fragrance for candle making are often the best resource. They understand the technical requirements and can provide the necessary support.

By carefully reviewing these specifications before you purchase fragrance oil, you ensure that the materials you use will contribute positively to the quality, safety, and appeal of your finished candles. This diligence is a hallmark of professional product development.
