How do You Calculate the Required Volume of Fragrance oil?

Step 1 — Pick a candle container.

Candle volume depends on the size of the vessel and how much wax you can fit inside it. For example, we will say that a candle will weigh 6.35 ounces (wax and oil). Even if the vessel is 10 ounces, it doesn’t have to be completely full.

Step 2 — Determine the percent of fragrance you want to use

The right amount of oil can only be worked out experimentally, and everybody likes it differently. As an example, we’ll use 10% of the oil.

Step 3 — Find out how much candle wax to use

So, we learned that our candle needs to weigh 6.35 ounces and would like a 10% aromatic load. Now, we can use the formula to find out the amount of candle wax:

Amount of wax = Volume of the vessel / (1 + Fragrance oil (%))

In this example, we are getting a wax quantity of 5.87 oz.

Step 4 — Find out the oil amount.

Now that we found out the weight of our candle and we have calculated the weight of the wax that we are using, it is easy to work out the amount of oil:

Amount of fragrance = Volume of the vessel – Amount of wax

Thus, we find that our candle requires 0.48 oz. of oil.

Frequently Asked Questions

What happens if you use too much oil?

If we add too much oil, our candle may not burn properly. The flame may burn off extra oil that hasn’t been able to mix into the wax if your fragrance load is too high, producing a heavier-than-usual dark smoke.

Another crucial factor is the oil’s temperature at the time of addition. If oil is added at a temperature that is too high, the wax may burn out or the oil may disperse.

What if I add too little oil?

It’s quite possible that as the candle burns, you won’t be able to smell the oil. The heat of the melted wax will cause some of the fragrance to simply burn off.

How much oil do I need for an 8 oz candle?

Let’s use the formulas we talked about earlier. Let’s say we want to add 10% of oil to our candle. First, we need to find out the wax weight.

Wax amount = 8 oz / (1+10%) = 8 / 1,1 = 7,2 oz.

And now, we need to use another formula to find the oil amount.

Fragrance amount = 8 oz – 7.2 oz = 0.8 oz

So, on an 8 oz candle, we need 0,8 oz of oil.

Does fragrance oil brand matter?

The process used by various manufacturers to create essential oils varies. Some try to reduce the price of the oil without sacrificing its quality and natural qualities. Others, on the other hand, produce it using unique recipes and exclusive suppliers with the intention of using it professionally in therapy and aromatherapy.

Additionally, several brands only use specific types of oils, which are also reasonably priced.

The oil you choose solely depends on your preferences, but buying natural oils is advised. They have been tried and tested for years and won’t hurt your health.

What are phthalates in fragrances?

Phthalates are phthalic acid salts and esters that are used to add softness and elasticity to plastics and cosmetics. They are incredibly cheap, so producers use them in massive amounts to reduce the price of a product.

For good reason, phthalates are classified as hazardous chemicals. They build up in the body and are extremely harmful to your health. Phthalates can occasionally be identified by the marking as the letter “V” or the abbreviation “PVC.” However, manufacturers frequently omit to list the ingredients and cover up dangerous ingredients with the word “fragrance.”

The majority of phthalates are found in synthetic oils.

What is an oil flashpoint?

The temperature at which scented oil becomes flammable when in contact with a flame or fire is known as the flashpoint. Those who manufacture gel candles and choose the delivery techniques are typically the only ones who require the flashpoint.

Some age waxes call for aromatic oils with a 170°C or higher flashpoint. The candle scented oil’s flashpoint can also determine whether it can be sent via airmail or if ground delivery is required.

Even though some aromatic oils have a lower flashpoint, if they don’t come into contact with a spark or an open flame, they are safe to use in molten wax. Wax heated to about 185°C will not ignite when aromatic oil with a flashpoint lower than that is poured into it.

What about chemicals in fragrance oils?

Some dishonest producers do add harmful chemicals to their oils. You can use any fragrance oil that is worthwhile by looking for one that has an IFRA certificate from the International Fragrance Association. Finding brands with all the required certifications is simple online.

If you cannot determine the origin and composition of the oils, do not order them. If at all possible, stick to reputable brands.
