Sugar of Lead

Tuesday January 8, 2008
One way you might suspect lead is leeching from your plumbing into your water is if the first water from the tap tastes sweeter than water after the tap has run a while. Lead tastes sweet. In fact, lead (II) acetate [Pb(C2H3O2)2·3H2O] is a compound that has another name: sugar of lead. Sugar of lead has been used as a sweetener throughout history. No honey or sugar? No problem! There is a calorie-free alternative. It's toxic, but you won't put on pounds from eating it. If you use enough of it, you might forget to eat altogether. The perfect diet aid.

The ancient Romans would boil down grape juice in lead pots and use the resulting syrup to sweeten wine and preserve fruit. We all know how it went down for the Romans, but lead acetate is still in use today. Have you noticed some lipsticks taste sweet on your lips even though, when you read the ingredient list, they contain no sugar or other sweeteners... well... except the lead acetate. Lead acetate is found in red lipsticks more than other colors. The chemical helps with colorfastness, which is why it's also using in dyeing, including progressive hair color, like Grecian Formula™ for men. You can have a head of youthfully dark hair, all the better to attract that lovely lady with the ruby red lips and the sweet, sweet kiss.

I have been a happy receiver of Dr.. Helmenstines chem letter for some time. I am a wish I could have been chemist since childhood, 83 years ago; I have a small fun lab set up in my back room. I am a lover of the Dr. Thank you for keeping it simple for us wantabees.

Great article! It even motivated me to go and research this even further. I am just amazed at the role lead played in the Roman empire. From sweetner to plumbing. Even today, it is still in our plumbing and paint (at least the stuff we get from overseas.

I have recently developed gout, and found that lead sugar was a common cause. I have been drinking very cheep, inexpensive red wine imported from South America, and France. do you think that these wines made contain lead sugar?

HaHaHa!!!

The wife and I were having a debate on some chemical names (Mostly about an element called Einsteinium) and then the chemical debate continued.

Great article! Love your wit. It does make you wonder what would happen if all cosmetics were required to display their ingredients. (not to mention wines and other things we all consume)
