So I don't know if you guys have ever had the opportunity to make your own soaps, but it is a whole lot of fun. And, honestly, its not as hard as you might think. First off, there are not a whole lot of ingredients in soap. You can make an awesome soap with just two or three ingredients in fact. The important thing to note is that you need to get your lye to fat ratio correct for the soap to firm up and set nicely. And thankfully we have the internet. So you can find tons of
soapmaking calculators on the net and use just about any of them to get as complicated or as easy as you want in terms of the science.
So here's the way of it. First you decide what oil you want to use. Lots of oils can be used, just about any of them in fact. But if you want a good quality soap, you need to make sure you are using a good quality oil. Some people use salvaged bacon fat, some people make soap from oil they throw out of their fryers regularly. And that oil you used to deep fry your crazy turkey at thanksgiving? Save it. You can make soap out of it. You just have to know what kind it is (Canola, peanut, vegetable) to know how much lye you need to add. Basically, all soap is made from is oil and lye and then with fragrance added.
So I ran to a friends house on Saturday and spent the whole day taking pictures and making a record of our soup making endeavors. Here we go. First off, you assemble your ingredients.
In this case we were making soap from Olive Oil (via Coscos) and Lye. Lye is very caustic so have some vinegar on the counter when you are making soap to splash onto anything and any body parts that might get lye on it. Where do you get the lye? Household drain cleaner that's 100% Lye in the hardware section of the store. You know, right next to the liquid plumber. So the things you see on the kitchen island there are a crappy mixer got at a garage sale for 3 bucks that can mix and mix and mix soap all day and if it dies, no one cries. Then you have a very accurate kitchen scale, Olive Oil, Lye in the drain cleaner form, and a big keg of coconut oil (it comes kinda hardened and has to be microwaved). There are some sample bars of soap sitting out on the counter two from the last batches. From left to right they are 100% coconut oil soap, half and half with olive oil soap, and 100% olive oil soap.. no colorings added, and each are scented. These are just half of a mold, not cut into bars yet.

Oh and here's the drain cleaner I was talking about.
So basically we made two batches. Each batch makes about twelve bars. You measure out your olive oil (these batches were 80% OO and 20% Coconut Oil), add in your lye, and let the mixer mix them for 45 minutes to an hour until the ingredients combine and the whole thing traces. Tracing is where you dip a spoon in, lift some out, and drizzle it across the surface and it stays in the drizzle for a little while before it melts back into the mixture. Cake mixes trace when they are ready too.
Here we are measuring out more olive oil in beakers.
So, once you get the olive oil mixed, you're going to need to add your lye. You need to liquify lye in order to get it into the soap and working. To do that you add the powder to the water. The lye calculators will help you decide how much lye you need (mixed with water) to add to whatever volume of oils and fats you have. So take the advice of the calculator and then take whatever that ounce amount of lye is and add it to a an almost two to one ratio of water... it will give you mL's or weight (I always use weight not volume) when doing complex science (which this is not). So anyhow, like I've said, Lye is caustic as hell, so you should have gloves, a face shield, etc on when working with this stuff. We didn't because we are adults and had someone there with vinegar to set anything to right that could have gone wrong. Remember, when doing exothermic reactions, always add the dry to the liquid, never add the liquid to the dry.. it can go badly. So we took the water outside, and added the lye to it and stirred rapidly. Lye stinks when put in water and the fumes can gag the whole room... so do it outside.. and stir until things calm down. What do I mean? That beaker got smoking hot, boiling hot, instantly and we had to wait until it cooled and the fumes were gone before we carried it inside.

Here we are outside mixing lye with water. Whew its hot and stinky!
So then what do you do? You have your pre-measured and weighed olive oil and coconut oil out in the blender bowls and you start them whirling. Then you slowly and gradually add the lye in. Then you go do something fun for like 45 minutes to an hour. Meanwhile the mixers in the kitchen where whirling away and not doing anything much.
So what did we do? We decided to make fragrances. This is my friend and mentor Elwin making up fragrances and my other friend Kat hanging out being excited by sniffing said fragrances. Laugh, but its a lot of fun making custom scents. I got my own made up for me too and I love love loved it.
So Elwin wanted to make a christmasish earthy type scent which she knew would be right up my alley. I'm big into the christmas flavors as we say.. citrus, cinnamon, evergreens, holly, etc. I love that stuff like a squirrel loves nuts. So in perfumes you have a base note, a middle note, and a high note. The base note to my scent was citrus, with a middle note of cinnamon, and a high note that stretches out as balsam which smells a heck of a lot like a forest just after its rained. This combination was divine. I wish I could post up a piece of blotter cloth so you guys can scratch and sniff, but that's not possible under current technology. Just know that we made scents... that's all thats important.
Elwin perfecting her blend.
Then Kat, who was also there making soap, wanted to make a custom blend for her soap, so Elwin asked her a few questions and then started mixing as well. Kat had lavender, patchouli, yang yang, Stridex (which is amber base), lavender, and some rose. It was a very earthy hippy smelling thing with a lot of happy notes which was perfect for Kat, who is crazy about rollerderby (and skates on a local team) and does all things simply in her life.
So.. after we had fun smelling all the scents, putting combos together, and deciding what our soap would smell like, we made four ounces each of our chosen soap scent. Then, by this time an hour and passed, the soap was tracing, so we dumped the four ounce vials into each soap respectively and then let it spin for another ten minutes to get the scent well and blended. Then, we poured out the soap into molds and will let them set about a week, check on them, and then go from there.
Those tins are the tins you'd find at a restaurant salad bar. They are stainless steel, and perfect for soap molds because when the soap shrinks enough to be released its ready to be unmolded.
The final product of soap poured into molds. I'll take some pics in a week when we unmold and slice them into bars. I'll take pictures when we unmold them next weekend.
I hope you liked seeing this. It was about an 8.5 on the Jen's Scale of Fun, especially since the guy in the photo - Tom, Elwin's Husband - is a lot like Bill Nye the Science Guy or Cisco if you know gardening and are out in Seattle. He is absolutely just as enthusiastic and fun to be around as those two celebrities and we had such an incredible time.
