yes, i make my own products for the very same reasons listed above, because of the odd chemicals, that i cannot pronounce, i dont want them in my body, i quit using typical deodorants, because there are hardly any (w/ exception of burts bees,) that DO NOT have aluminum in them.. i personally dont feel like have to deal with alzheimers later on in life.. or for my loved ones to get it. I make my own soaps because when i use my own soap, my skin doesnt get dry and itchy, and i dont use tooth paste for the very same reason, most of them have products in them i dont want in my body. This is also why i make my own laundry soap and especially my own fabric softener.
So, for me it's a lot about being healthy and staying healthy in all the ways i can. If i eat right, but am using toxic things to take care of my body, all the other "balanced" things i do would be pretty useless. I just prefer balance all around.
hope this answers your questions. take care, kiya
