Understanding the Science Behind Wax Stratification

When it comes to understanding the science behind wax stratification in soy candle making, exploring the molecular composition is essential. Wax stratification occurs when the components of the wax separate into layers due to differences in molecular weight and polarity. This phenomenon can result in an uneven distribution of fragrance oils and dyes, leading to candles with inconsistent scent throw and color.

To delve deeper into this topic, let’s take a look at the molecular composition of soy wax. Soy wax is primarily composed of triglycerides, which are long-chain fatty acids attached to a glycerol molecule. These triglycerides consist of various types of fatty acids such as palmitic acid, stearic acid, and oleic acid. Each fatty acid has a different molecular structure and characteristics that play a role in determining the behavior of the wax.

Factors such as temperature and mixing techniques can greatly impact wax stratification. When heated, the triglycerides in soy wax melt and become more fluid, allowing for better mixing of fragrance oils and dyes. However, if the temperature drops too quickly or if improper mixing techniques are used, stratification can occur. It is important to maintain a consistent temperature throughout the melting and pouring process and to use proper techniques like stirring gently but thoroughly to avoid separation.

To prevent stratification during candle making, selecting the right soy wax is crucial. Different soy waxes have varying molecular compositions, which can affect their susceptibility to stratification.

Frequently Asked Questions

What happens if you add too much fragrance to soy wax?

Adding too much fragrance to soy wax can have negative effects on the quality and performance of the candle. Soy wax has a limited capacity to hold fragrance oils, so exceeding this capacity can result in issues. One consequence of adding excessive fragrance is poor scent throw, meaning that the candle may not release a strong and consistent aroma when burned.

Additionally, an overload of fragrance can cause the soy wax to become oily or greasy, impacting the appearance and texture of the candle. It may also result in incomplete burning or uneven melting, leading to wasted wax and an inefficient burn time.

Why is my soy wax candle crumbling?

Crumbling in soy wax candles often indicates a problem with the wick selection or improper pouring temperatures during the candle-making process. If the wick size is too small for the diameter of the container, it may not generate enough heat to melt all of the surrounding wax evenly, causing parts of it to be left solid and crumble when burned.

Similarly, if the temperature at which you pour melted soy wax into its container is too low or significantly lower than its recommended pouring range (usually around 110-135°F), it can lead to uneven cooling and contraction before fully setting up, resulting in a crumbly texture.

Why does soy wax crystalize?

Soy wax crystalizes due to a natural phenomenon called “frosting.” This occurs when soy wax cools down quickly after being melted and poured into containers. The appearance of tiny white crystalline structures on the surface or sides of a soy candle is known as frosting. Frosting does not affect how a soy candle burns or its scent throw; instead, it usually results from how soybean oil reacts with temperature changes during cooling.

This phenomenon is unique to soy wax as other types of waxes do not exhibit frosting tendencies. Some people even consider frosting as part of the natural charm and authenticity of soy candles rather than a defect. However, if you wish to reduce frosting, ensuring slower cooling rates, using preheated jars, or experimenting with different soy wax blends can potentially minimize the occurrence of crystalization in your soy wax candles.
