I have had my soaps certified and one of the rules seems to be that you have to print off and attach all of the MSDS sheets for all of the ingredients to your certification document. I have to admit I haven't got around to this yet, partly because I can't believe it. I have over 30 ingredients, each MSDS sheet is at least 3 - 4 pages long, my printer won't print back to back, which leaves me with over a hundred pages to print out full of largely pointless info about fairly safe products (the coconut oil sheet I note says you might slip over on it!) that I will almost certainly never look at. All of this info is available at the click of a button on-line if you buy from reputable suppliers. The only ones that I can't access easily on-line are a few products I buy from the supermarket, like coffee and sugar which soap suppliers won't supply. I've just e-mailed Tesco about this. What have other people done? I am guessing I need to bite the bullet and do it, but it seems quite ridiculous to have to have all this rubbish in hard copy when it would actually probably be quicker, easier and more efficient to look it up on-line. I was thinking perhaps of creating an on-line folder with all the sheets gathered together. even that is probably less efficient than just looking it up on the suppliers website - which you are probably never likely to do anyway!
