What is the difference between Sodium Lauryl Sulfate and Sodium Laureth Sulfate?

While they're both surfactants, SLES is like SLS' more gentle cousin.

There's some scientific differences also if you're more interested in that.

What are the pros and cons to each? I am still a bit foggy on the subject :?

Well really they can be used interchangeably because they do the same things.

These blogs has a wealth of scientific information on sulfates (plus a bazillion other things):
http://swiftcraftymonkey.blogspot.com/search?q=sulfate
http://personalcaretruth.com/?s=sulfate

SLS
Pros: Inexpensive
Cons: Well known skin irritant to people with sensitive skin, associated with a huge cancer myth

SLES
Pros: Known to be gentler than SLS
Cons: Costs a little more

Sodium Lauryl Sulfoacetate (SLSA) is a gentler alternative to Sodium Lauryl or Laureth Sulfate.

Ahhhhhh, I see. Thank you all!

I have made a small batch of MP soap out of pure glycerin and added coconut and palm oil to it as well as fragrance, but I didn't get much lather and the soap was rather hard. I thought maybe I should add some SLS to it to at least get more lather. Is this a good idea or no?

Where did you get the base? Is it synthetic based or does it have more natural ingredients?

Not knowing any better I got it from Hobby Lobby. Cost me quite a bit more than my goats milk :( Looks like a lot of synthetic ingredients. After my first batch is when I decided to look more into how to make soaps. I figured there was a lot more I needed to know to get a quality soap and low and behold I was right! There is sooooo much for me to learn and I appreciate all the help I am getting here!

Welcome to the forums! :D

There are big differences in base quality, especially from Hobby Lobby & Michaels. My favorites are the . They are excellent soaps. There is a that includes 1 lb of each of the seven types they carry for $20. Awesome to have around even if you're a CP soaper.

I bought a goat milk base from Bulk Apothecary but haven't used it yet. It is on back order. Wish I had found this site first :( I didn't know the low reviews people have for BA. Had I known they pull the back order thing all the time and had (historically) awful customer service, I would not have bought from them.

The products I DID receive I like though. Bought lip balm base and flavor oils from them and had good results.
