Candle Making Additives

If you are just starting out on your home candle making business, the chances are that you will be consulting various resources for instructions and troubleshooting. It is highly likely that the use of additives will crop up at one point or another. Here is a quick rundown of some of the most common candle making additives together with tips on when and why they should be used.

Before getting into detail about each individual type, there are a few things to consider when working with these products. Use of any additives in your candles will usually affect the way the dye works with your wax. Your dye recipes may need to be adjusted when using additives.

In addition, additives will most likely have an effect on your wick size. Because they are often used to increase the wax’s melting point, you may need to adjust your wick size accordingly.

Here are several of the more commonly used additives that you may likely have a need for at one time or another.

Candle Making Additives


One additive you will hear frequently discussed is vybar. Vybar acts as a binding agent and is used to make wax more opaque. Vybar can also be used to reduce air bubbling and mottling effects in your candles.

Stearic Acid

This is another popular additive, which increases the scent throw of your candles by making it possible to add more fragrance oil to the wax. Stearic acid also helps your candles achieve a smooth, even finish.

Universal Additive

Several companies also produce what is referred to as a Universal Additive. This has several functions, some of which are to help in mold release, harden wax, bind oil to wax, increase opacity and lengthen candle burn time.

UV Stabilizer

One additive that most candle makers will find extremely useful is UV Stabilizer. If you sell your candles outdoors or under fluorescent lights, you may want to seriously consider incorporating this additive into your finished product.

UV Stabilizer is added to candles to help prevent candle fading and to improve the stability of the color. When exposed to light, some candle dyes will fade severely. In other cases, dye and fragrance oil may not react well together and over time, the color may fade. The use of Universal Additive helps combat these annoying problems.

Other products that you may sometimes see advertised as additives are beeswax and petrolatum. Beeswax is often added to wax blends to increase the overall burn time of a candle. Petrolatum is commonly used to soften the wax and to increase the melt pool.

Every additive has one or more specific, intended uses. As you gain candle-making experience, familiarize yourself with these additives and consider whether they may benefit your candle products.

Some candle makers choose to not incorporate additives at all. Some wax blends are pre-blended and sold with the additives already included. Check with your suppliers and consult various resources if you believe your candles may benefit from one of these many candle making additive options.
