That's awesome for a 9% vanillin soap, Todd! It will be interesting to see if it darkens over time.

Any plans to try metabisulfate + thiosulphate? My thought was that maybe they are synergistic.
That combination had crossed my mind but I will have to do some research and see how they would react to each other.
I’ve been doing a little research. Found this on a site for crafters choice vanilla stabilizer. Then I looked up disulfurous acid, disodium salt and it looks like the metabisulfate is indeed the same thing. It does list it’s percentage in the CC stabilizer as 20-30% however. I love this experiment!
That is great research. I only made 2ozs, so when I make more I will lower it to 30%. As a note, I used white mica and I'm not sure if I didn't use enough and the darkening that occurred is not a natural occurrence do to the color of the FO because that is exactly the color of the FO.

Here is another picture of the test batch. I pulled the sides away as far as I could and it is not the best picture. It is hard to see but it is much whiter than the separate test bars in the other picture. Also it is hard to tell how much the gelling affected the outcome.

After it was to late, I realized, I should have poured out a little bit of soap without the VCS or mica as a comparison to the VCS treated soap. Maybe tomorrow I will try another batch, with better test bars.

My goodness, it looks very white! And no rind showing, either. I'm cautiously hopeful!!

Here is an update after 19 hours. The pictures are not the best.

The first picture is the un-gelled bar, absolutely no change.

2nd picture is the gelled batch. The soap is a off white but in order to show the shading on the edge, I had to modify the picture. That's why it looks darker than it is.

3rd picture is modified but it is definitely an off white or dull white, if you will. I circled the edge so that you can see the darkened edge.

Note: I used 1.8ozs of FO but after looking at my notes I realized that I only used 1.5ozs of metabisulfate. I don't know if that had any effect on the VCS working properly but I don't think it did. Because @Jersey Girl research would be mean that I have a stronger formula than what they sell.

I am going to try a mix of sodium thiosulfate and metabisulfate either today or tomorrow.

So if I am understanding this correctly, the actual color looks more like the last bars? If so, that's pretty amazing for the first try of a homemade solution! Of course you don't want the off-white or the shading if possible, but I'm guessing that you are going to nail this down. Great job!

So here are my current results using sodium thiosulfate crystals, the first photo with the darker ring is the day of cut. Second picture 2 days later, and latest one today, a week after cutting. I did plane them at some point but I think they are now back to the point they would have been regardless. I am also attaching a picture of how dark the fragrance is supposed to discolor to. This is similar to a prior experiment where the fragrance did not discolor the soap to a dark brown but did to a dark beige

@glendam that is some good results. I think the combination of thiosulfate/metabisulfate might be the key to unlocking this mystery and some incredible $$$ savings.

I got my sodium metabisulfate on Amazon. The brand that I got is the same one that most brewing supply companies sell. I will post the link.

This is the best deal I could find and it should last a long time. Compared to the cost that some of you are paying for VCS, this should be a huge cost break.

Thank you! I was just looking at the one from make your own, it is cheaper ($3.50 a lb) but with the shipping it would be more costly. It would make sense if I was buying more things from them. Which incidentally, I did place an order from them for citric acid a few days ago, but they are unable to add items to orders once placed!

Rats, I too just placed a big (for me) order of oils and other stuff from Make Your Own (aka SaveOnCitric, aka ChemistryConnection - why do they have so many names, haha?). It probably wouldn't have changed the shipping much, if at all. I still need to use up the VCS that I have from Bitter Creek, but would love to have this on hand when I'm ready to use it.

Same here! I could have gotten their metabisulfate, but my mind was on bath bomb making stuff!

Just in case anyone in the US wants a good deal on the Sodium Thiosulphate, here ya go

Gosh, this stuff is used in all kinds of different things: wine-making, photography, soap-making, aquarium cleaning. But will it make my coffee in the morning? ;)😄

Make your own sells on eBay and most of the time I get it faster than from their website. It is where I got my EDTA.

The pictures are horrible but once I get my new lighting box tomorrow, I will get some better pictures and by then we will see what 48 hours shows.

When I get back from the Dr tomorrow, I am going to make an orange/chocolate FO soap. The chocolate has 6% vanillin from save-on-scents, with the description saying medium brown.

Last night I made a chocolate FO soap with 6% vanillin using the 50/50 metabisulfate mix.

Today I'm going to use a 30% thiosulfate, 30% metabisulfate solution. I guess that it is a 3,3:1

I believe that the suppliers who sell VCS are using this blend. Because when I mixed the 2 together it had a very slightly green hue to it, which is exactly the color of the VCS I use from aztec candle. It is still clear, just a tint of green if you like. However I am not sure what ratio they are using.

I'm going to use a FO with 9% vanillin that turns dark brown today and I will post those pictures tomorrow.
