How To Use Stearic Acid In Candle Making

Introduction

Candle making is a great hobby and an excellent form of self-expression. By using stearic acid in candle making, you can increase the quality of your candles and make them last longer. Stearic acid”which is also called octadecanoic acid”is a type of fatty acid compound that acts as both a thickening agent, increasing the hardness of wax, and as an emulsifier to help ensure consistent blending of scent, color dyes and other additives into the wax.

When used in candle making, stearic acid gives the finished product superior shelf life properties while at the same time providing better shape retention when burning. As it helps to increase the thermal stability and frost resistance in candles, this means they will burn more evenly, reducing ‘beading’ or ‘tunneling’ of hot wax down the side of jar and container candles.

Usage Guidelines – How To Effectively Utilize Stearic Acid



Before using stearic acid for candles, mix it into liquid paraffin without heating either ingredient first”this will result in a mixture which looks like soft white cream cheese when cooled. Use this mixture when adding extra hardening ingredients to your candle wax like beeswax chips or granulation thereof; adding up to one tablespoon per pound should do it. Keep in mind however; adding too much will make wax brittle causing cracks later on when being burned in containers or trying to pour over larger candles (tapers).

For use with Paraffin Wax it is recommended that no more than 3% be added based upon total weight for standard dip taper types such as Spiral Tapers ” any higher content may cause issues if not blended properly prior to dipping so try 20 grams per 500 gram batch instead i.e., 4%. With Pillar Candles you can use simple math again to reduce risks associated with using excess amounts ” try 5 grams per 500 gram base = 1%; 10 grams per 1000 grams = 1%. For Container Candles keep it less at approximately 1/2 percent by weight e.g., 15 grams for every 5 liters for products without added fragrances where higher temperatures may not be necessary during oxidation cycles so there won’t be need for additional “stiffening” agents due their already high viscosity ratings.

By following these guidelines on how to effectively utilize stearic acid in candle making processes, you can be sure that your finished products will have good burning characteristics while providing excellent shelf life properties. Additionally, since most waxes are extremely flammable even at low temperatures avoiding too much stearic acid usage is paramount ” too much can cause uneven pouring or crackling sounds during wick lighting possibly causing safety hazards during burning due its quick melting capabilities which could ultimately lead to fires!

What Types of Wax Are Best for Using Stearic Acid in Candle Making?

When using stearic acid in candle making, it is best to use a natural vegetable wax for the main base of your candles. These types of waxes include soy wax, beeswax, and palm wax. You can also use paraffin and gel waxes, although they may not hold their shape as well or last as long as a vegetable-based wax.

When combined with other ingredients such as essential oils and dyes, the stearic acid helps to create a stronger bond between the wax molecules while allowing them to mix and blend more easily. This creates a stronger structure within the candle that is more resistant to heat changes and softening during burning. Additionally, adding stearic acid increases the burn time of your candles by improving its ability to melt and remain solid at lower temperatures. The higher melting point of these type of candles also means that fewer volatile compounds are released into the air” resulting in less soot buildup on surfaces exposed to candlelight.

Preparing the Wax for Candle Making with Stearic Acid

Before you begin making candles with stearic acid, it is important to prepare the wax properly. First of all, measure out the appropriate amount of wax needed based on how many candles you desire. Place this wax into a double boiler and heat it until it has completely melted. Next, add the stearic acid to the melted wax in small increments and stir constantly until the stearic acid is fully incorporated into the liquid wax. Once all of the wax has been melted and combined with stearic acid, it should be immediately removed from heat to prevent burning or oxidation. Additionally, it can be beneficial to remove any solidified particles from inside of the mixture before using it for candle-making by pouring through a sieve or strainer. Finally, at this point you are ready to begin making candles with your now prepared mixture of stearic acid and liquid wax!

Steps for Adding Stearic Acid to the Candle Wax

1. Begin by melting the candle wax in a double boiler or crock pot on low heat.

2. After the wax has melted completely, add the desired amount of stearic acid to it in increments of one teaspoon at a time. Make sure each spoonful has been completely dissolved before adding more of the powder into the mix.

3. Mix the stearic acid in to ensure that it is thoroughly blended.

4. Once all of your desired amount of stearic acid has been added, allow it to cool slightly once removed from heat (around 145°F or according to your personal preferences).

5. Add any fragrance oils, dye chips and/or other ingredients you would like for your candle if applicable and stir until everything is blended evenly throughout their wax mixture.

6. Begin pouring into container molds following personal safety instructions during this process as well as letting the melt set overnight before moving onto additional steps such as finishing off with wicks or labeling!

Tips for Wicking the Candle and Selecting the Appropriate Flame Size

When using stearic acid in candle making, the best way to correctly wick and create the appropriate flame size is to submerge the end of the wick into a container or bowl filled with melted stearic acid. Make sure that you heat up the stearic acid enough so it looks like a liquid. Hold onto one end of the wick as you lower it and leave it submerged for around 30 seconds before lifting it out of the acid. As it dries, try different heights until you achieve your desired flame size.

Additionally, when choosing a wick and deciding which one is best suited to your particular project and container, use one that is ‘pre-waxed’. This means that it has had wax applied to its flat end which allows an easier and cleaner burning when applied to a candle. After this process, hold onto either side of the wick between two fingers before dipping into the melted stearic acid so that it can be spread more evenly while submerged into the liquid stearic acid.

To adjust flame size after setting up your wicks, trim them accordingly so they only reach 3mm above your candle’s surface. This allows for an even utilization of wax and will produce smaller flames when lit, ideal for prolonging burn time, scent diffusion and visual aesthetics of candles. However if you’d like larger flames then allow them to reach 5-7mm from your candle’s surface instead prior to lighting up each time; this will ensure long lasting flames with some mild crackles from time to time during usage.

Adding Color and Fragrance to the Finished Candle



Stearic acid is a wonderful additive for creating candles with extra strength, shine and texture. The acid can also make the candle resistant to melting in hot weather, while simultaneously increasing the hardness of the candle wax. Once properly melted, stearic acid can be added to the molten wax in order to give your candles an extra boost. It is also important to note that when using stearic acid in candles, one must take into account the respective flame size of each type used when adding it so flames are not too large for your vessel.

Adding color and fragrance are an important part of finishing off a candle made with stearic acid. To achieve this effect, additional items such as dye blocks or liquid dye and essential oils should be added to the mix before pouring into molds or containers. Once you have perfected the amount of color and scent for your particular candle design, it’s time for pouring ” simply combine all ingredients according to instructions, stir thoroughly and slowly pour into whatever final form you require! This process also includes adding a wick which will allow your creation to burn once lit. Finally, be sure to allow wax time to cool overnight before trimming the excess wicks!

Benefits of Using Stearic Acid in Candle Making

The benefits of using stearic acid in candle making include an increased level of strength and stability, a longer burning time, and enhanced scent dispersion. Stearic acid is usually added to candle wax in proportions ranging from 1-3%, while the other two components are beeswax or soy wax. The presence of stearic acid helps to stabilize the material and increase its melting point. It also helps strengthen the surface layer of the candle, providing a longer burn time. Finally, molecules of stearic acid attract the molecules emitting scent particles which helps disperse them more evenly throughout your home.

Conclusion

Stearic acid is a popular ingredient for candle makers for its ability to produce a long-lasting burn. When added to the wax in the right proportion, stearic acid helps candles become harder and less prone to melting or deforming. This makes them ideal for situations where the candle must remain lit for extended periods of time. In addition, it also ensures that your candles will maintain their scents longer since stearic acid works to trap any essential oils or fragrances within the wax. Not only does this make your candles more visually appealing, but it also carries their smells further from the source. It’s no wonder why people often turn to stearic acid when creating custom candle creations!
