Candle Perfumery





You could spend a lifetime in the study of fragrances and even then you wouldn't know all that is to be known. However, science has made giant strides over the past hundred years and chemists can now replicate any odour very precisely in the laboratory - perfume manufactures spend millions doing this every year, it's a multi billion pound industry.

When I say they can closely replicate any smell, that means good or bad. One manufacturer has even produced a  fun fragrance called "Monkey Fart" which smells like, well yes, Monkey Fart - we're not quite sure what species of monkey was used as a model, but let's hope it wasn't gorilla, because that's not nice :).

Fragrances for candles are no different from any other perfume, they are made up essentially from short chain organic compounds (the shorter the chain the more volatile and short-lived is the fragrance).

You will hear perfumers speak of top (or high) , middle (or heart) and bottom (or base) notes of a fragrance, with the high notes being the highly volatile components you smell immediately and doesn't last very long, The middle notes are bigger molecules which take longer to evaporate and appear perhaps after a few minutes as well as lasting a lot longer, then finally, the really heavy bottom notes which don't develop in sufficient concentration for a much longer period perhaps even hours and can last for days. So with any fragrance, there is an initial belt which hits you, and after some minutes the perfume develops a much rounder character and finally you get left with the lingering base notes.

NB: The heavy base notes are longer chain molecules and tend to be more expensive to produce or obtain which is why many cheap perfumes don't contain so much and consequently are not so long lasting.

Candle perfumes use exactly the same components as any other commercial perfume and come distributed in a light oil which will mix readily in candle waxes (to a greater or lesser degree). If you imagine a candle wax as a sponge, you should be able to visualise how the perfume gets distributed and held in the wax matrix and while some of the lighter molecules will evaporate from the surface of the unlit candle in sufficient quantity to produce a detectable aroma (the cold throw) most of it is held locked in the matrix until the candle is lit.

Of course, it is in the interest of the candle maker to have some cold throw in order for customers to be able to select something they find pleasing. One thing you should understand though, is that very little of the fragrance of a candle is distributed (thrown) via the flame - in fact any that does get sucked up when the wax (fuel) burns, will be instantly destroyed in the very high temperatures that exist there and creates little or no odour. The smell from a candle actually comes from the melt pool, so the bigger and warmer the melt pool, generally the greater the throw will be (for a given fragrance). This is why choosing the correct wick for a scented candle is absolutely critical and this is why test burns of a new candle design are a fundamental part of the process for us candle makers.

If you think about it, you will realise there are a virtually an infinite number of variables you need to juggle to get consistent results. The perfume itself is a complex mix of organic molecules which evaporate at different rates, the wax used will determine how much of a given perfume can be held in its matrix, any additives (Stearin, Vybar, Bipol, Polymers etc. etc.) will have an effect on that too as will the size and shape of the candle and the configuration of the wick (or wicks). So, getting the combination right for any given candle is what sets apart amateurs from professionals and some candle manufactures can spend many months test burning different configurations to get the perfect result they and their customers are after. They will also retest for new batches of wax and new batches of fragrance because there can be subtle difference ( particularly with the wax - fragrances can be much more precisely controlled during manufacture).

Of course, a hobbyist just starting out can still produce exquisite candles by following the same techniques the pros use - test test test.

All of the fragrances we sell have been developed by expert perfumers specifically for use in candles and are safe and consistently good from batch to batch. We aim to test all of the fragrances we receive with the waxes, dyes and wicks we sell, to check their performance and give us the raw data that allows us to offer sensible advice to newcomers and established makers moving to our range of products - you can be confident of being able to achieve very good results with your own candle designs.

Because there are an infinite number of variables of wax, perfume concentration, additive concentration, and wick it is impossible for anyone to predict exactly which wick to use for a given application and combination of elements, but we can offer a guide on which wicks may be a good starting point, after that it's down to you and your testing. As your experience grows, you will get better at selecting the perfect wick for your projects.

As we mentioned above, testing is absolutely fundamental to candle making success and hand in hand with that premise is the keeping of good records so you can reproduce results consistently. We have created a Candle Design Record sheet which we use for our own testing and we have made a version available for free for our customers to use for their own records if they choose to.

Always buy from you and am very happy with the service. I was a little worried when the product I buy was out of stock for a while. However when I called, your sales assistant was very apologetic. She explained what the problem was and assured me that it would be in stock soon. She offered to let me know when the item was back in stock and I received an email today so, I would like to thank Paula for the email and the rest of the team for great customer service. Thank you.

This is definitely the best UK site I've found for candle making. I haven't made them before and lack of options was making me hesitant to try this. But I found your site and I'm definitely going to try it, I've wanted to do it for ages and was held back by high delivery prices and prices of oils. So I'm very grateful to have found your site and will most definitely use it again!!
