Because your bath bomb contains red, yellow and blue pigments, as we know: red + yellow + blue = black.

Many people don’t like this color, especially children, black scares them. To change this, you can only choose the color at your discretion, don’t let all three colors exist at the same time in your products, or the amount of one of the pigments should be very small.

Why soap “sweating”?

This is because glycerin absorbs moisture in the air. Glycerin is a natural by-product of saponification and can also be added as a moisturizer. “Sweating” is a normal occurrence and is not a quality issue.

Are there any preservatives in soap?

Not, you never have to use preservatives in any soap, the soap have a pH level(from 8-11) that doesn’t allow mold or bacteria growth.

Is cold process soap better?

USA: F2417, F2601, F2058. Learn more

Why it has wet spots in candles?

Because of thermal expansion and contraction, this is not a quality issue. Wet spots appear when the wax is pulled away from the edge of the container. and dissolving and cooling are the key steps in candle making.

Why is my candle seeping oil?

This happens more often with soy wax, which is more sensitive to extreme temperature changes. It causes the fragrance oil to separate from the candle. Also, when the fragrance oil is not compatible with the candle, sweating occur.

What causes a candle to smoke and how to correct?

Due to incomplete combustion, lack of oxygen in the flame.

Specifically for the product itself, it may be because the wick is so long that it cannot absorb the wax to the top, and the wick keeps burning causing the smoke.

What cause the frosting on candles and how to prevent?

The frosting is the crystalline layer that forms on the surface of natural waxes (e.g. soy wax) as an attempt by the natural wax to return to its natural state. It does not affect the performance of the candle.

The following methods can reduce frosting during production: 

Do not stir the melted wax vigorously, prevent the candle from cooling too quickly.

What is “tunneling” in a candle and how to prevent?

Tunneling means that when the candle is burning, only a small part around the wick melts, we also call it “insufficient burning”, this is a quality defect.

Tunneling is related to the size of the wick. If a candle with a large area uses only a very small wick, then heat is certainly not enough to melt the whole plane. So the size of the wick and candle should match each other when making. 

Why soy wax is better?

Natural, Burns Cleaner, ECO. 

What is the best storage ℃ for candles?

Around 20℃, no more than 30℃. If too heat, it will bleed oil even melt, if too cool, there is wet spots. 

How to choose the size of the candle wick?

It depends on the size of your candle, generally, a 100g candle needs a 24-27 strand wick so that it burns well and doesn’t hang on the walls.

The cotton wick is never wrong, it has strong water absorption, will continue to absorb wax, and use it as fuel to burn constantly.

Reed Diffuser

Is it necessary to use alcohol in diffuser oil?

Not, we can use other solvents, but adding a little alcohol can make it diffuse faster.

Is diffuser oil DG for transport if there is alcohol?

If you add too much alcohol, thus making the flash point of the oil exceed 65, then it will be judged as dangerous under the regulations. We have done the testing, 6% alcohol or less is generally safe.

Can I just use essential/fragrance oil for the diffuser?

No. The Standard oil is too thick to diffuse(or diffuse too slow), it does not allow the fragrance to fill the entire space.

How many times the reed diffuser can be used?

The reeds should be turned for every two to three weeks to keep the scent alive. This is because over time the reeds become completely saturated and can become clogged with dust.

Can a diffuser use for different scent?

This is not recommended, once the reeds have been used for a certain scent you should not use them for others, the scent already absorbed by the reeds will mix with the new scent and may produce a strange smell.

How many reeds should you put in a diffuser?

We recommend starting with 6-8 reeds, but you may choose to add more. Be aware that the more reeds you use, the more fragrance you will release, and the faster the liquid will be used up. Pair your reeds with a smooth clear or silver glass bottle.

How long should a reed diffuser last?

Typically 1-6 months, depending on the amount of aroma oil, and how many reeds you used. However, the most critical thing is the solvent used in the oil.
