Fragrance Oils in Candle Making

What’s the difference between fragrance and essential oils?

Essential oils (EO) are 100% natural. They are made from plant material most commonly by either steam distillation or pressing/expelling. These are classed as natural ingredients.

However, we don’t recommend using essential oils in candles for a few reasons:

1. Most EOs have a low flash point which means they will burn off when you light the candle so you won’t get much scent throw.

2. Some EOs can be toxic – especially to pets and children.

3. They can be expensive – especially when you will get very little scent from a candle containing EOs!

Fragrance oils are made from a mixture of synthetic ingredients and natural ingredients. That’s why you can get thousands of different fragrances that aren’t possible with essential oils.

All our fragrances have been tested extensively and have IFRA certification. Our fragrances come from two of the worlds leading fragrance manufacturers based in the USA. All our fragrances are safe to use in candles.

How do I get my candle to smell stronger?

Getting a better scent throw is one of the most commonly asked questions, there are a couple of tricks you can follow to try and maximise the fragrance strength in your candle:

1. Add the fragrance at the optimal temperature of 80-85°C and make sure you stir well for 1-2 minutes so it binds properly to the wax.

2. Use the correct wick size.

3. How big is the room the candle is burning in? Often people complain they can barely smell their candle, while forgetting they have a travel sized tin burning in a large living room. The bigger the room, the bigger the candle needs to be. It doesn’t matter if you use the maximum amount of fragrance oil in a candle – it still won’t smell very strong if it’s in a large/open area.

4. Let your candle cure. 1 – 2 weeks is the optimal time for curing.

5. Don’t over-fragrance. Make sure you’re not using more than the maximum fragrance load for your particular wax. Despite what many people may thing, adding more fragrance won’t necessarily make your candle smell stronger.

Can I mix fragrance oils together?

Sure! Mixing fragrances yourself is the perfect way to get a “custom blend”. The candle market is full of Vanilla or French Pear candles, why not get creative and make your own unique scent.

The easiest way to get started with fragrance blending is to go by drops.

For instance, if I wanted to make a coconut, pineapple and strawberry blend I could start out with:

1 drop coconut
1 drop pineapple
1 drop strawberry
Result: The pineapple was way too strong and I could barely smell the coconut or strawberry

Second attempt:

3 drops coconut
1 drop pineapple
2 drop strawberry
Result: Much better!

 Now I have my blend I can mix this up into a larger bottle so I need to translate drops into millilitres.

To fill a 500ml bottle with my custom blend I would use:

250ml Coconut (3 parts)
83ml Pineapple (1 part)
167ml Strawberry (2 parts)

Do your fragrance oils discolour?

It depends. Many of our fragrances contain natural ingredients such as vanillin, citrus oils and spices. These can all cause discolouration – over time and exposure to sunlight you may notice your candle turning yellow – brown.

There’s nothing wrong with your candle or the fragrance, this is just a natural occurance when using certain fragrances.

Try to keep your candles out of sunlight by storing in a cool dark place and using lids where possible.
