Ever wondered what the difference is between an Essential Oil and a Fragrance Oil? Below we will cover the differences between the two, recommended fragrance ratios and more!

What is the difference between Essential and fragrance oils?

Essential Oils are made from natural ingredients using processes such as steam distillation and solvent extraction. Fragrance oils are made from synthetic materials with added chemicals to enhance the aroma.

Recommended Ratios

Essential oils usually have different viscosity than fragrance oils as they are made from natural ingredients, while fragrance oils mainly contain synthetic components. As natural oils tend to be more viscous, we recommend using them at a lower ratio. If you are looking to make a candle using essential oils, we advise testing your candles with 6-8%, whilst 15% would be a good starting point for your diffusers. If you prefer fragrance oils, you can start testing your candles with 8-10%, and our recommended diffuser ratio is 15-20%. Please always check the oil product page, as some oils may be subject to limitations under IFRA/CLP guidelines.

We recently introduced new concentrated fragrance oils. You`re able to use a lower ratio with these products. Depending on your wax, our recommended ratio is 3-5% for candles, whilst with diffusers; we would advise you to start testing with 8-10%.

Which wicks are most suited for my oils?

The choice of wick will depend on which wax is being used. LX or TG wicks work well with mineral waxes. Stabilo, CL, V, TB, ECO or PGS wicks can be used with mineral or vegetable blends, while VRL wicks are suited to blends containing a high percentage of plant wax. Overwicking can cause larger flames which can then form larger melt pools and generate more soot. Overwicking is the term used to describe the use of a larger wick than necessary for a particular candle.

What does viscosity affect?

The viscosity will be different for each oil and it is affected by temperature. As temperature increases, viscosity decreases. Fragrance can be quite viscous at room temperature, so warming it up a little before adding it to your wax can help the two materials to mix better. You will achieve a better hot throw when adding fragrance to hotter wax as the hot wax lowers the viscosity of the fragrance - and the wax too - making it
easier to get good fragrance distribution. This can be achieved at lower by simply mixing for longer.

Please Note:


Please ensure you conduct your own testing to ensure you are satisfied with the finished product as the above information only provides you with a starting point for your testing.


Your CLP label must be present at the point of purchase, meaning that if you sell online, the CLP information must be present on the product page. You are required by law to label your products and packaging. Our CLP label design tool is freely available to create your labels for all your products.

Generic Warning Labels: You may be able to use a generic warning label if the used oil doesn`t trigger any hazard warnings under CLP regulation. You can confirm this by referring to our free CLP label design tool to ensure you remain legally compliant, as the generic warning label doesn`t display any hazard-relating information.
