SLSA you can get from MMS. There was one other company that matched MMS' price, but cannot remember who that was. Possibly the Chemistry Store.

Since Scented answered your 2nd question, I'll try the first...

I measure .1oz on my digital jeweler's scale (measures hundredths/oz). I use assorted sizes of Dixie/plastic cups to hold the ingredients I'm measuring. Soap suppliers sell disposable plastic eyedroppers which work great for dropping tiny amounts of liquids into your cup. 1/10th oz. of liquid is more than what it sounds like it would be when you're using those little eyedroppers.

P.S. When weighing ingredients, don't forget to subtract the weight of your Dixie cup (tare weight). Or put the empty cup on your scale and set the scale to "0", if you can.

Another helpful thing is if your recipe is in a formula is to use grams (its more precise when making smaller batches IMO). If not, you can always convert it (herbalsoapsbyrj.com has a lot of good calculators to do so). I also have a small scale that measures to 1/100th of a gram which I could not live without. I now do all my formulating for any soap/B&B in grams. When I package to sell or ship, then I use lbs/oz....but otherwise I stick with grams.

It is also a lot easier to take a formula to grams than a formula to ounces in my opinion. For instance say you are making 100 grams and it calls for 35% well that ends up being 35 grams. If you are making 500 grams, it ends up being 175 grams. If you are making 1000 grams, its 350 grams. It takes less math work IMO.
