How to make 10% vanillin solution?

[purelyscientific]

Its been a while since I've played around with making EM solution and I'm not sure if making vanillin solution would be any different.
That being said, some help would be much appreciated.
I usually just order pre-mixed 10% vanillin solution from WL but I use so much of it I decided to purchase an ounce of pure vanillin powder off of ebay to mix my own.

Intuitively, I guess that 1gram would be enough to make 10mL correct? My goal is to make 60mL of 10% solution.
Again, any help would be much appreciated. Thanks in advance!

I did mine by volume. Actually did 30%. 3 ml vanillin powder added to 7 ml pg. Tried 10% first and thought it was very weak. Even the 30% doesn't carry much flavor to me. At 30% everything dissolved perfectly. I use a Hobart hobby paint shaker for mixing. Works well but slows down too much if I use a bottle over 15 ml. Was going to try 50% but have not yet.
Really don't know how close my method is to the end percentages, but it's close enough for me.

SNip:

Ethyl Vanillin 10% Solution – Crystals to liquid – ¼ tsp to 10ml PG? Unsure
Great sweetener + Vanilla taste.

Some say 1/4 tsp to 8ml PG is more accurate to 10%

 

[purelyscientific]

So that would mean 3.75 tsp...or 1.25 tbsp.. would make 60mL 20% vanillin solution..sound about right?

6 grams of powder to +- 56ml of pg for a 10%. this is where those volumetric flasks that WL sells come in handy...

 

[purelyscientific]

So 1.07g(approx 1.1g) per 10mL would be a 10% solution according to those figures.

That would mean;
6.42 grams for 10% 60mL
12.84 grams for 20% 60mL
19.26 grams for 30% 60mL

I usually use 7-20% in my mixes. I use it as the base flavoring. So making a higher concentration will last longer and will also give me more freedom with my pg/vg ratio and nic level. I'm going to make the 20% solution.

not quite exact, but it would work.

I place a 50ml Volumetric flask on an accurate scale and measure out 5 grams of powder (for 10%, use 10 grams for 20%) then fill the flask with pg to 50ml mark (be sure to stir and get any air bubbles out).


Volumetric Flasks are cheep and very handy.

How is it not exact? Care to elaborate?

because "+- 56ml" was a guesstimate, your math is on. The final amount of diluent can differ depending on the density the powder or crystal. Still, your method will result in more constant results than '1/4 tsp in 10ml'.

I misunderstood what you were saying. I thought you were saying my math was no exact. *shrugs*

'Just jumpin' in and sharing our experience with vanillin crystals...

We made two 10% solutions (one with VG/PGA and one with straight VG) using 1 gram of crystals & 9ml of fluid, and then made samples with that at .5%, 1%, 2.5%, 5%, 7.5% & 10%.

After about a week of steeping, we tested them. The most intense flavor did not come from the 7.5% & 10% samples; the flavor was most intense from 2.5% & 5% vials...and we couldn't discern much of a difference between those two. We still didn't have our head around the whole "less can be more and more can be less" for vaping flavors/chemicals, so we tested them again a few days later to be sure our taste-buddies weren't hallucinating...still the same. (no mistakes on the bottle labeling - the color intensity matched the percentages).

So, for those that don't already know...there are many 'vaping flavors' & chemical additives that actually lose or change their flavor (and/or cause other flavors to be 'less' or changed) when used in large amounts. This is definitely counter-intuitive...but "more" does not always equal "more" when DIYing.

I'm getting some FA vanillin crystals and going to try the guide lines in this thread as I would guess should give the same results? Anyone else tried it?

1 gram = 1ml

1.0 tsp =4.92892 ml

so you can just round it up to 1 tsp = 5ml to make larger batches.


Close enough for me.

I have done the vanillin the same way I do the em. Both are good. Can add a little sweetner(maybe a drop) if you like, tho not needed.

My understanding is you tested your already made 10% solution. Is this correct?
On your test samples, what did you use vg or pg or pga? And brought all back to a 10ml bottle?
thanks
