Iron Chemist: Sodium cocoyl isethionate (SCI)
Here are the rules. Every week I will ask my husband to choose a number between 1 and 10. These represent boxes of supplies in my workshop. Once he has chosen a number, he will choose an item randomly from the box and I must make 2 - possibly 3 - products that include that ingredient. I will post the ingredient on Sunday and the products I've made out of said ingredient on Saturday along with the recipes. (If you wish to play along, you aren't limited to the same time frame and you don't need to make 2 or 3 products.) The only exception will be preservatives - I use them in everything anyway, and it won't end up being a very interesting product!
Unlike Iron Chef, you don't have to make the featured ingredient the main ingredient because we don't want to use our ingredients at unsafe levels.
As a note, we've changed the way Raymond chooses boxes. Since I've added a new box, there are a total of 10. So he will roll a 10 sided die and then choose from that box. Since he has very little concept of what each box holds, he'll choose something randomly. We switched to this method because most people aren't likely to choose 1 or 10 when asked to choose a number between 1 and 10, and we thought every box deserved a fighting chance!
So what is SCI? Only my favourite surfactant ever! Here's a quick summary about this surfactant (for the entire post, click here).
Isethionates are considered exceptionally mild for skin, hair, and eyes, and are particularly tolerant to hard water. They leave behind a great skin feel - usually described as "silky" - and create really lovely foam, bubbles, and lather. SCI is great for every skin or hair type. The dry type will enjoy the gentle cleansing and the creamy after feel. The oily type will enjoy these features as well. SCI is great for a cream cleanser - the oils won't mess with the lather too much - and body washes. The down side is that SCI will make it difficult to make a clear shampoo, body wash, shampoo, or facial cleanser if you use the one with stearic acid.
The one Raymond has chosen is Jordapon prilled, which does not contain stearic acid.
So join me next Saturday to see the two or three products I make with this ingredient! As with last week, this is an ingredient I love and use in tons of different products - body washes, liquid shampoos, solid shampoos, hand cleansers - so it's going to be an interesting week as I try to figure out what to make!
