Hi kysmoothy and welcome! Bramble Momma gave you some very generous and helpful advice! I think you are asking questions that everyone has wondered, and might have been afraid to ask about when they first started making MP so don't worry, we are here to help! Anywhere you can purchase the oils that you are interested in, as there are some that do add oils to their MP soap, can be found in any grocery store, Walmart, some health food stores, etc.
1.) The soap might not have lathered because of the amount of FO and/or Vitamin E that you added, the ratio for oils to amount of MP can be Googled if your not sure or you don't know.
2.) A lot of people use Goat's milk because of it's moisturizing properties, vegans won't use it because it is a by product of an animal. But for MP you would buy a Goat's milk base. People that make CP would add Goat's Milk, please do not add it to MP!
3.) The ingredients that you have mentioned have been used in MP, I have seen it mentioned on here and in other forums and have seen these as ingredients in soaps that are melt and pour. It is a matter of opinion though, some people add small amounts to MP soaps, but in general these ingredients are mainly used in CP. Cold Process soap is a soap that is basically made from scratch that requires oils, lye, water and optional ingredients.
4.) Soap Queen has a calculator on her Bramble Berry website regarding the amounts of FO's and in what applications to use it in. If you need to know about another oil, I will PM you the info.
5.) Any grocery store or soaping supply web site.
6.) Already answered!
7.) The difference between the white and the clear is pretty much how you want to decorate or design your soap and how it will look when you are finished.
To those of us that have been a little outspoken as of late:People come on forums to look for help, advice, tips, show off their wares, etc., not to be talked down to or discouraged or belittled. I think there are those who should take a step back and remember how green, curious, without knowledge and inexperienced they were when they first started. I love this forum and have since the 1st day I joined it because there were adults on here who have helped, been helped, swapped product, formed friendships and have just been kind and generous with their nature in general. lately I have seen people be condescending, form clique type behavior and just be downright mean to people, I guess just because they can or because they possess more knowledge or experience or just because they feel that they are in charge.
