Dear Philippe,
Your request is a little bit disturbing. You are about to prepare something
like a mosquito repellant with no knowledge about the chemistry, physiology
and toxicology of it. Even if it is for your own use, it's a risky
business, nothing to say if you intend to sell the concoction to users or
distributors. There are certain regulations and quality control
requirements about the materials and products which doubtfully you can
fulfil, for commercially handling such formulations.
Be well,
Jacob
>Hi, I have no chemical knowledge at all but I need to dilute
>N,N-diethyl-m-toluamide (DEET C12H17NO CASnumber 134-62-3) in a proportion
>of 30%. I was thinking of water but on the technical datasheet I discover
>that it is not soluble in water.
>I don't need a perfectly homogenous liquid as long as I can shake it before

>Purpose is to use it on skin (human & animal), which requires a safe and
>less oily possible solution, but as the usage quantity and frequency will be
>high, I need a cheap product.

>Thanks for any suggestion.
