Yes! It's so true that it's even funny. I am a chemical technologist by education with a bias in inorganic chemistry, and one of the things that we were constantly told: we should always focus on the average value. I was engaged in crystal growth, and it turned out that we cut off the upper (purest) and lower (most polluted) parts from the grown crystal so that the bulk of the crystal was homogeneous. The cleanest part was used for seedings for the growth of other crystals, the most polluted part was used for melting. Sorry for the off-topic message. I'm happy to learn something new, like how to make candles, but I miss crystal growth very much. My last attempts to make candles led me to the idea that it is more convenient to pour wax into glasses when the melt turns white (the crystallization process begins). I don't know yet how to implement this correctly for a large number of candles, but I'm trying.

The manufacturer of fragrances offers fragrances on DPM (dowanol) in candles, but it is written on the Internet that this is also glycolic ether. Tell me, please, have you by any chance had any experience working with him?

Thank you all again for your answers! They helped me in a conversation with my superiors. It turned out that some of our fragrances use dipropylene glycol as a solvent. Perhaps someone knows why the fragrances with DPG work so poorly in candles?

I tried to heat the wax to this temperature, but the fragrance manufacturer (Givaudan and Frey & Lau) advised to lower the temperature, as part of the fragrance may evaporate. and now I try not to heat the wax above 170 degrees.

thanks for the advice! my first attempts to make a candle were attempts to make a candle from pure soy wax without adding fragrance and stearin. this allowed me to find a suitable wick. then I started adding flavor to find the best concentration. it turned out that the wax I used wasn't too good for making the candle smell, and my boss and I found wax with different physical characteristics. then my search was repeated again: I took the wick, raised the concentration of the fragrance. due to the fact that soy wax becomes strong only after a week, it was decided to strengthen it artificially with stearin. I started testing again. During the search I made about 100 candles, that's for sure. the problems started when it became necessary to produce them in large quantities, rather than 10-20 pieces per day. When I made test candles, I could heat their surface with a hair dryer to achieve a smooth surface, but in mass production this is impractical. I'm also thinking of trying to add a little coconut wax to a mixture of soy wax and stearin, but I'm afraid there will be too much difference in melting temperature, and the candle will burn incorrectly.

I forgot to clarify that candles are aromatic. I also selected the percentage of fragrance input, it does not exceed 10%, for some candles the fragrance concentration is less, but this does not affect the quality, unfortunately. I pour a mixture of stearin and soy wax into the heater. The wax melts at a temperature of 167 degrees , I introduce a fragrance and mix thoroughly, but do not shake (an experiment with a colored fragrance showed that it is not always so easy to completely mix it with melted wax). Then I wait for the temperature to drop to 122-125 degrees and pour the melt into glasses. The windows in the room where I make candles are always closed and people rarely pass by them, so I don't think it's a draft. I tried to experiment with the conditions in which candles freeze: I tried to make them on a grate, in cold water, in warm water, in a heated glass, in foil, far or close to each other. I also used a different range of melting temperatures, fragrance input and pouring. But the 167-125 interval is the most convenient.

Yes, I think the same way, unfortunately, I don't have as much time to search as I would like. I would be glad if someone could tell me the name of some good literature, because it seems that I have already seen everything about candles on the Internet.

We order wax from a distributor of raw materials, unfortunately, I do not know the wax manufacturer, and the supplier does not disclose this information so that we do not decide to buy wax directly from the manufacturer (this is my assumption). I usually carry no more than six percent stearin(a mixture of stearic acid and other acids), since when more than six percent is added, the wax begins to form a depression around the wick.

Hi, my name is Sarah. Recently I started making candles. At first they turned out really good (as far as I can judge as a novice candle manufacturer), and my boss and I (this is a small factory) were happy with everything, but the problems started when it became necessary to introduce the technology into mass production. Since we have a "made-sold" system, in order to speed up the process, I had to add stearin to soy wax (I read that this makes the candle harder and increases gorenje time). I tried all possible options: correlated the melting and pouring temperature, the size of the wick, the temperature in the room, the surface on which the candles solidify. I do not know, maybe the problem is in the container (glass cup) — but I am already desperate. At the beginning of the attempts, I did not think that soy wax could be so capricious): In one approach, I try to make from 50 to 70 candles, of which (at best) only 20 will be good, the rest have different defects (tunnels, uneven surface, cracks at the wick). I am melting wax in a wax foundry, is it possible that the wax has been in a molten state for a long time?If someone had similar problems and you were able to solve them, please share your advice
