Catalysts[ edit ] Polyurethane catalysts can be classified into two broad categories, basic and acidic amine. Tertiary amine catalysts function by enhancing the nucleophilicity of the diol component.
I had an anti-fluoride patient the other day that was saying he read somewhere that a pea-sized amount of toothpaste contains the same amount of fluoride in 1 liter of tap water 1 ppm. So he was wondering if he should call poison control every time he drinks more than a liter of water. It sounded ludicrous, but how much fluoride is actually in a pea-sized amount of toothpaste in comparison to 1 liter of water?
Fluoride Warnings on Toothpaste Click to enlarge I enjoy talking about water fluoridation. I took a picture of the back of three different brands of toothpastes: Colgate, Aquafresh, and Crest.
If you click on the picture, you can view a large size that will let you read the warning. Each tube has a similar warning. The back of the Colgate Total toothpaste box states: If more than used for brushing is accidentally swallowed, get medical help or contact a Poison Control Center right away.
But how much do people really use for brushing? I decided to find out how much toothpaste is in a large stripe by conducting a two-part experiment.
My Toothpaste Experiment On the back of the toothpaste tube, it states that you should call the poison control center if you swallow more than is used for brushing.
This is what the toothpaste manufacturers write. I took the liberty of assuming that a normal amount of toothpaste for them is a thick stripe on a manual toothbrush like they show in their commercials. I decided to find out exactly how much toothpaste is in a big stripe so that I could figure out how much fluoride it has.
I got carried away and tried two different brands. If not, it may be time to get a new toothbrush: Out of curiosity and because it seemed like a fun idea after taking two finals over the past 36 hoursI measured the Crest Toothpaste as well.
I was able to get a slightly bigger stripe on the brush this time. However, if you want to practice making a beautiful stripe of toothpaste on your brush, I have to recommend the Crest since it is much thicker. Contrast this with a pea—size amount of toothpaste which is only 0.
Now that we know how much toothpaste we use, we can figure out how much fluoride we would ingest if we swallowed a large stripe of toothpaste.
How Much Fluoride is in Toothpaste? A majority of toothpastes on the market contain about 0. In a pea sized amount of toothpaste, you would only find 0. How Much Fluoride is in Fluoridated Water?
Most fluoridated water contains about 1. That means that in 1 liter of water, you would find about 1 mg of fluoride. Not sure how much fluoride is in your water?
Then find out how much fluoride is in your tap water! Comparing the Amount of Fluoride In Water with the Amount of Fluoride in Toothpaste As you can see, you would have to drink over 2 liters of water to get the same amount of fluoride that you would get by swallowing a large stripe of toothpaste.
You would only have to drink ml of water a little less than a 12 oz.Headquarter of Diesel located in Molvena Italy Aquafresh toothpaste Aquafresh from BUSI at Liberty University. Find Study Resources. Headquarter of Diesel located in Molvena, %(10).
