How do you calculate fragrance oil for wax melts? ›

We simply explain it as the ratio of fragrance oil to the weight of your wax. Yes, 30g is 10% of 300g, but it's not 10% of the wax weight, which is what you need. A 10% scent load of 300g would actually be 30g of fragrance oil added to 300g of wax, making your finish product weight 330g.

Most waxes will hold no more than 12% of fragrance oil however to assure the candle stability is not compromised we advise using 10% fragrance oil for optimal scent throw. This means if your candle is 100g in total- 90g should be wax and 10g would be your fragrance oil.

Using too little fragrance may result in a low scent throw, while using too much may get a strong hot throw and overload the wax, and cause candle sweating or curdling. The fragrance oil ratio may also impact what candle wicks to use and how the melt pool of the candle turns out.

Calculating Fragrance Oil for Your 8 Oz Candle

Determine the weight of your wax in ounces. Multiply the weight of the wax by the fragrance load percentage (e.g., 7%). This gives you the amount of fragrance oil in ounces to add to your candle.

The amount of fragrance oil needed per pound of wax varies based on factors like the type of wax and personal preference. As a general guideline, a fragrance load of 6-10% of the wax weight is often recommended.

Add your fragrance at the right temp: Adding your fragrance oil when your wax is at the proper temperature will help it bind to the wax, which will help give you a stronger scent throw. It is usually recommended to add your fragrance to the wax at 180-185F for soy and paraffin wax 200-205ºF for palm wax.

One pound of wax should make you two 14 oz candles with some wax left over. So 10 lbs should be more than enough.

The molecules in the candle wax and oxygen from the air combine and rearrange, and release heat and light as they do so. Optional: use molecule models to show a simple version of the chemical reaction: CH4 + 2O2 → CO2 + 2H2O.

A: The industry standard is considered 0.5 ounce of fragrance per pound of wax. For double-scenting, you would use 1 ounce of fragrance per pound of wax. For triple-scenting your candles you can use 1.5 ounces of fragrance per pound of wax.

Which Candle Wax Gives The Best Scent Throw? Currently Paraffin waxes are considered the best for achieving a strong fragrance – this is why many high street brands still use paraffin wax in their candles.

What is the best percentage of fragrance oil in candles? ›

Calculating the percentage of fragrance to use

Most waxes will hold no more than 12% of fragrance oil however to assure the candle stability is not compromised we advise using 10% fragrance oil for optimal scent throw. This means if your candle is 100g in total- 90g should be wax and 10g would be your fragrance oil.

There is no one set answer to this as basically it depends on how strong you want your handmade wax melts to smell once they are heated. You may even want to experiment a bit with different amounts. The maximum amount you should use is 10% oil to wax ratio – so for 100g of wax you would add 10g of oil.

Once you have decided on how much to use, add the fragrance oil to the wax once the wax has fully melted in the mould/container and stir in for at least two minutes to allow it to fully bond with the wax.

Everywhere I've looked online it says you should be using around 10% ml fragrance oil to the grams of wax. So 100g wax means 10ml oil. Given that most easily sourced bottles of fragrance oil are 10ml this would mean a whole bottle per 100g and that's not exactly a huge candle.

Chemical formula of candle wax:

The chemical formula of candle wax is CnH2n+2. N is the number of carbon atoms that can vary. Basically, it is a hydrocarbon, and the exact formula can be determined by examining the type of wax used in the candle-making process.
