Question 1

can i use this when diy body lotion? what is the difference between this procude and urea & allantoin?

Accepted Answer

This should be safe for cosmetic products, but I would definitely suggest contacting jacquard to see about its purity (usp grade is 99.9% pure).  As to the difference, urea and allantoin are two different compounds.  Urea on it's own is a generic humectant with some emollient properties.  It has been used in lotions and balms up to 40% for skin redness and irritation.  Allantonin has the same functions as urea, but is more emollient in nature (think lanolin) and is the more common ingredient used in cosmetics due to these properties.  To make matters more confusing both allantonin and urea are BOTH referred to urea because of annoying naming conventions.  So to sum up, you should be able to use this just fine though I'd contact the company.  Urea is a little more therapeutic in use and a generic humectant, while allantonin will give you that softer creamy glide along with softening and humectant properties.  Side note:  urea is ubiquitous in labs for so many things, but I wanted to focus on your question regarding use in lotions.

Question 2

Can I just pee in a bottle and use that instead?

Accepted Answer

It's certainly worth a try! But would ferment it for a week first to make it more concentrated.

Question 3

how do you use the urea for tie dying tshirts? and how much do you use?

Accepted Answer

We used it as a dye additive for the purpose of keeping the colors bright (which, I believe, the urea does by slowing the dye's ability to dry.)  We've only dyed just the one batch of shirts I can say that the colors haven't faded after several washings.  In fact I would venture to say the color has held as well--if not better--than commercially dyed shirts.  However I cannot directly attribute this to the use of the urea since, like I mentioned, I haven't dyed without it.  The amount to use should be on the instructions, but it wasn't much (we measured in teaspoons or tablespoons, if I remember correctly.)
