Soap is the sodium salt of fatty acids, there may be several similar fatty acids in any given commercial soap, maybe a little extra fat, maybe tiny bit of perfume and pigment. The glycerin is usually removed. It's the fatty acid anions that do the work of removing soils, including lead.

Hillman to: TechNet 01/12/2012 03:20 PM Sent by: TechNet <[log in to unmask]> Please respond to TechNet E-Mail Forum, ddhillma Hi Doug - whomever said we learned everything we needed to know in life in kindergarten was correct - including using soap when we wash our hands! There are oodles (aka many) things in soaps that lead loves to grab onto and make stable compounds. If people follow the prescribed practices for correctly handling solder/lead and use proper hand washing practices, then the need to hand wipes is not necessary.

Was I aware of any industry studies on the efficiency of hand wipes marketed at removing lead residues, presumably from contact with cored wire solder? I was not aware of any. I am always instantly suspicious of ANYTHING that marketers touch. I am of the opinion that good old fashioned hand washing with soap and water is as effective as anything, but there are areas here where we are pretty sure our operators go straight from the bench to lunch without that step. So, I turn to my favorite source of information. 1. Are you aware of any industrial hygiene studies regarding transferrence of lead to the hand, and/or the efficiency of "lead removal wipes" in removing residues. 2. In your facilities, do you use these kinds of wipes? 3. If not, what measures do you normally use for operators cleaning hands to remove potentially harmful material? I will probably discuss this with our crackerjack metallurgist when he returns from travel tomorrow, but thought I would ask in the mean time.
