Mixing Wax and Fragrance Oils: Step-by-Step Guide

Mixing wax and fragrance oils is a crucial step in making scented candles. Here’s a step-by-step guide on how to do it:

Materials needed:

  • Candle wax (paraffin, soy, beeswax, etc.)
  • Fragrance oil
  • A double boiler or a wax melter
  • A thermometer
  • Stirring utensil (a spoon or spatula)
  • Candle molds
  • Wick (with wick tab and glue)

Step 1: Prepare your work area and materials. Ensure your work area is clean and free of debris or flammable materials. Set up your double boiler, a heat-safe container, a thermometer, and a stirring utensil. Place your candle molds on a flat surface and insert the wick, ensuring it’s centered and straight.

Step 2: Melt the wax. The easiest way to do so – is a wax melter, but you also can use the double boiler method. Place the wax in the double boiler or heat-safe container and heat it up slowly until it melts. Monitor the temperature using a thermometer and ensure it doesn’t exceed the recommended temperature for your wax type.

Step 3: Add fragrance oil. Once the wax has melted, remove it from the heat source and let it cool for a few minutes. Add your desired amount of fragrance oil, usually between 6-10% of the total wax weight. Stir the mixture thoroughly for at least 2 minutes, ensuring the fragrance oil is evenly distributed throughout the wax.

Step 4: Pour the wax into molds. Carefully pour the scented wax into the prepared molds, making sure not to spill or drip any wax. Fill the molds up to the desired level, leaving some space for the wax to contract as it cools.

Step 5: Let the candles cool and cure. Allow the candles to cool down and solidify completely, which usually takes a few hours or overnight. Once the candles have hardened, remove them from the molds and trim the wick to the desired length.

Step 6: Enjoy your scented candles! Light them up and enjoy the aroma in your home or give them as gifts to your friends and family.

Remember to always follow safety guidelines when handling hot wax and fragrance oils, such as wearing protective gloves and keeping a fire extinguisher nearby. With practice and patience, you can create beautiful and fragrant candles that will fill your home with warmth and ambiance.

Safety Precautions When Mixing Wax and Fragrance Oils

Mixing wax and fragrance oils is a common practice among candlemakers. While it may seem like a simple process, important safety precautions must be taken to prevent accidents and ensure the quality of the finished product. Here are some essential tips to follow when mixing wax and fragrance oils:

  • Always work in a well-ventilated area. Wax can release harmful vapors when heated, and prolonged exposure can cause respiratory problems. It’s crucial to have good air circulation in your workspace to minimize any health risks.
  • Use protective gear such as gloves and goggles while handling hot wax or fragrance oils. Hot wax can cause severe burns if it comes into contact with your skin while splashing fragrance oil can irritate your eyes or skin.
  • Ensure the wax temperature is within the recommended range (185°F – 200°F or 85°C – 93°C) before adding fragrance oils.

The Most Fragrant Combinations of Wax and Fragrance Oil

Many combinations of wax and fragrance oil can create wonderful and fragrant candles, but some of the most popular and effective ones are:

  • Soy Wax and Lavender Essential Oil: Soy wax is a popular choice for candle-making because it is natural and eco-friendly. When combined with lavender essential oil, it creates a calming and relaxing aroma that is perfect for use in the bedroom or during a spa day.
  • Beeswax and Vanilla Fragrance Oil: Beeswax has a natural honey-like scent that can be enhanced by adding vanilla fragrance oil, resulting in a sweet and warm aroma that is perfect for use in the kitchen or living room.
  • Palm Wax and Lemongrass Essential Oil: Palm wax is a hard and long-lasting wax that is perfect for creating pillar candles, and when combined with lemongrass essential oil, it creates a fresh and invigorating aroma that is perfect for use in the bathroom or during a workout.
  • Paraffin Wax and Sandalwood Fragrance Oil: Paraffin wax is a popular choice for making scented candles because it is easy to work with and can hold a high concentration of fragrance oil. When combined with sandalwood fragrance oil, it creates a warm and woodsy aroma that is perfect for use in the office or study.
  • Coconut Wax and Jasmine Essential Oil: Coconut wax is a natural and eco-friendly wax with a creamy and smooth texture. When mixed with jasmine essential oil, it creates a romantic and sensual aroma that is perfect for use in the bedroom or during a date night.

It’s important to note that the specific ratio of wax to fragrance oil will depend on the type and concentration of the fragrance oil used and the desired strength of the scent. It’s always a good idea to conduct a small test batch to determine the optimal ratio for your specific combination of wax and fragrance oil.


What is the ratio of fragrance oil to wax?

The ratio of fragrance oil to wax when making candles is 0.5 ounces of fragrance per pound of wax. This ratio ensures the scent is strong enough to fill a room without overpowering it. It also ensures that the scent won’t fade quickly, so your candle will last longer. 

When using this ratio, it’s important to use high-quality fragrance oils and waxes. Cheaper ingredients may not produce the same results as higher-quality ones, so it’s worth investing in quality materials if your candles smell great and last a long time. Additionally, make sure you properly measure out the amounts of oil and wax you’re using – too much or too little can throw off the ratio and affect the strength of the scent.

How much fragrance oil do I add to 1kg of wax?

The amount of fragrance oil you add to 1kg of wax depends on the type of wax and the intensity of the scent you wish to achieve. Generally speaking, 10% is a good starting point for most types of wax. This means that for every 1kg of wax, you would add 100g (or 10 ml) of fragrance oil. 

It’s important to be aware that different types of wax may require different amounts of fragrance oil to achieve the desired scent strength. For example, soy wax typically requires a higher concentration than paraffin-based waxes. Additionally, some fragrances are more potent than others, so it’s always best to start with a small amount and gradually increase until you reach your desired scent strength. 

Finally, when adding fragrance oil to your melted wax, make sure it is completely blended before pouring it into molds or containers. This will ensure an even distribution and consistent scent throughout your finished product.

What happens if you put too much fragrance oil in a candle?

If you put too much fragrance oil in a candle, it can have a negative impact on the performance of the candle. The fragrance oil will overpower the wax and can cause the flame to burn too hot, leading to sooting. Additionally, if there is too much fragrance oil in the wax, it may not be able to hold as much heat as necessary for an even burn. This means that your candle may tunnel or create an uneven surface as it burns down. To avoid these issues, using the correct amount of fragrance oil when making candles is important. A good rule of thumb is to use no more than 10% fragrance oil by weight compared to the wax used in your candle.

How many drops of fragrance oil for soy candles?

The amount of fragrance oil used for soy candles depends on the desired scent strength. Generally, use 1 to 2 ounces (30-60 ml) of fragrance oil per pound (450 g) of wax for a light scent. For a medium scent, use 3 to 4 ounces (90-120 ml) of fragrance oil per pound (450 g) of wax. For a strong scent, use 5 to 6 ounces (150-180 ml) of fragrance oil per pound (450 g) of wax. 

When using essential oils instead of fragrance oils for soy candles, 100 drops should be used for every pound (450 g) of wax. Essential oils are more concentrated than fragrance oils and may produce an overpowering smell if too much is used. It’s best to start with fewer drops and increase the amount as needed until you achieve the desired scent strength.

How to mix candle fragrance oils?

You’ll wondering, but mixing candle fragrance oils is a great way to create unique scents for your candles. The process is relatively simple and requires only a few basic supplies. 

To start, you’ll need to purchase the fragrance oils of your choice. Be sure to check the oil’s flashpoint before purchasing, as this will determine how much heat is needed for the oil to vaporize and disperse its scent. You should also make sure the oils are compatible with one another. Different types of fragrance oils may react differently when mixed together, so it’s important to do some research beforehand. 

Once you have all of your supplies, you can begin mixing! Start by adding a small amount of each oil into an empty container, then slowly increase the amounts until you get your desired scent. It’s best to mix in small batches so that you can experiment with different combinations without wasting too much product.

What wax holds the most fragrance?

Paraffin wax is a popular candle choice because it holds the most fragrance. This is due to its high melting point, which allows the fragrance to be held in the wax longer than other types of wax. Additionally, paraffin wax is less expensive than other types of wax, so it’s a great option if you’re looking to make candles on a budget. Finally, paraffin wax has a higher melting point and is not as brittle as other types of wax, making it easier to work with when creating candles.

Why is my fragrance not mixing with wax?

Fragrance oils and waxes have different properties, so mixing them together is difficult. The most common issue is temperature. It won’t blend properly if the wax is too hot or cold when adding the fragrance oil.

Another possibility is that your fragrance oil has gone bad. Fragrance oils can oxidize over time, losing their scent and becoming less effective in wax melts. It’s best to use fresh oils for optimal results. To tell if an oil has gone bad, smell it directly from the bottle – if you can’t detect any scent, it’s time to replace it with a new one.


Mixing wax and fragrance oils is a great way to create your own unique scent combinations. With some practice, you can create a variety of scented candles, each with its own unique aroma. Remember proper safety instructions when working with hot wax, and always wear gloves when handling fragrance oils. Additionally, make sure to use the right ratio of wax to oil for optimal results. Finally, have fun experimenting with different scents; don’t be afraid to get creative!
