Whether you’re experimenting with new scents or refining your candle-making process, gaining insight into this crucial aspect will elevate your craft and ensure every candle you create is a fragrant success.

Determining the Ideal Fragrance Load for Soy Wax

When working with soy wax, the amount of fragrance oil used per pound significantly impacts both the scent throw and the candle’s overall performance. Fragrance load refers to the percentage of fragrance oil added to the wax by weight. For soy wax, this load typically ranges between 6% and 10%, depending on the specific wax formulation and the desired scent intensity.

Using too little fragrance oil results in a weak scent throw, while exceeding the maximum recommended load can cause issues such as poor scent retention, wax sweating, or even structural problems in the candle. It is crucial to follow the wax manufacturer’s guidelines and consider the fragrance oil’s compatibility and strength.

Common Fragrance Load Guidelines for Soy Wax

Most soy waxes are formulated to hold a fragrance load of around 6% to 10%. Some specialty soy wax blends allow up to 12%, but exceeding this is generally discouraged. The exact amount depends on:

  • The wax’s fragrance holding capacity
  • The fragrance oil’s strength and concentration
  • The candle’s intended use and size
  • Desired scent throw (cold and hot)

Typically, a fragrance load of 6%-8% offers a moderate scent throw suitable for most candle sizes, while 9%-10% is used for stronger fragrance impact.

Fragrance Oil Quantities per Pound of Soy Wax

The following table provides a reference for how many ounces of fragrance oil correspond to various fragrance load percentages per one pound of soy wax:

Fragrance Load (%) Fragrance Oil (oz) per 1 lb Soy Wax Fragrance Oil (grams) per 1 lb Soy Wax
6% 0.96 oz 27.2 g
7% 1.12 oz 31.5 g
8% 1.28 oz 36.3 g
9% 1.44 oz 40.8 g
10% 1.60 oz 45.4 g

This conversion is based on 1 pound equaling 16 ounces (approximately 454 grams), making it easier to scale fragrance additions depending on batch size.
