There’s money in Menthol

Cool, Clean Feeling Menthol is the most important flavoring chemical. Without menthol it would be difficult to get that cool clean feeling when we brush our teeth or chew gum. Cough syrups and drops wouldn't cool the throat and open nasal passages. World Wide Production of Menthol In 2007, it was estimated that production of menthol was in excess of 19,000 metric tons.  Because of it's importance, there is a huge demand for this flavor chemical. It is a natural material and therefore subject to price fluctuations as a result of envrionmental conditions. Natural Menthol Naturally, peppermint oil (Mentha piperita) contains approximately 35-45% menthol and corn mint oil (Mentha arvensis) contains 65-75% menthol. Mentha arvensis is largely … [Read more...]

Methyl salicylate, Artificial Wintergreen oil (FEMA 2745)

Aspirin conversion to Methyl salicylate A standard lab experiment in organic chemistry is to convert aspirin(acetylsalicylic acid) to Methyl salicylate. Methyl salicylate(FEMA 2745) is an ester which smells sweet, is strong, is approved for use in food and is the characterizing flavor of wintergreen. Wintergreen flavor is very popular in the United States. Countries like Japan and Italy think it's most suitable for cleaning bathrooms, but not for eating.   My Impression Personally, Wintergreen is one of my favorite flavors. It not only adds cool minty flavor, it adds sweetness. You can taste wintergreen in toothpastes, candies, gums, rootbeer, and bubble gum. Yes, that's right, root beer. Try a swig of rootbeer;  doesn't it taste … [Read more...]

Colgate Total Advanced fresh+whitening fresh gel, flavor review

An interesting fact about toothpaste is that it's considered a cosmetic product by the FDA. Toothpaste is something we place in our mouth and possibly ingest, but one of it's primary purposes is to freshen breath (cosmetic). Toothpaste without flavor is terrible. I know, I've tried it. It's very soapy and bitter. Usually toothpaste manufacturers add at least 1% flavor (mint oil) to toothpaste for the desired affect. In 2004, I moved to Washington state to work with mint oil. One of the major growing regions for mint in the United States is the Northwest. Approximately 3 million pounds of Peppermint oil are produced annually in the world, with the majority of that oil coming from the United States. The Mint Industry Research Council … [Read more...]

Crest Complete Whitening +Scope Citrus Splash Review

Flavoring toothpaste isn't the same as flavoring food products. Number 1, toothpaste isn't ingested and has different regulations than a food product. Number 2, toothpaste is typically basic and most food products are acidic.  Mint oils and especially menthol are extremely stable and hold up well in basic and acidic conditions. Therefore, besides the fact that mint freshens breath, it is a good flavor choice for toothpaste. I imagine, though, that there are some people who want choices and feel like mint toothpaste is too harsh or not pleasant. Recently, Crest complete launched a Citrus Splash flavored toothpaste.   It has an aroma reminiscent of St. Joseph's baby aspirin, a creamy sweet orange flavor. Those of us born in the 1960's, before … [Read more...]

Sensodyne Pronamel Isoactive review

Most of us, as we age, lose some of our teeth's protective enamel layer and have sensitivity. I first noticed sensitivity on the right side of my mouth at the gum line at age 30. At that time, my dentist recommended "sensitive" toothpaste, brushing on the left side on my mouth first, a mechanical toothbrush and fluoride treatment for that area. From a recent Wall Street Journal article about Enamel Saving toothpastes, I gather my problem is a common problem.http://wp.me/p1RL8o-2O For sensitivity, I use Sensodyne, it's the toothpaste my dentist recommended years ago and the one he gave me free samples of. Sensitive toothpastes are not inexpensive. Usually, they are approximately 2-3 dollars more a tube. I imagine the Potassium Nitrate at … [Read more...]

Colgate Optic White Sparkling Mint review

Whiter Teeth? Wow! Just one brush with this product and I'm sold. I have a good feeling that my teeth will actually be whiter in 4 weeks. I have used the expensive whitening strips and have found them effective, but as a busy mom not practical to use. Of course, I've inquired about teeth whitening at the dentist office, but can never justify taking from my kids College fund, just to have brighter teeth. My Impression How come I think this toothpaste will make my teeth whiter? After all, I only brushed one time with it. My reasoning is that it leaves a taste in my mouth just like the whitening strips, but not as unpleasant. Silly, huh, that it reminds me of a product that works to whiten teeth, I feel confident that it will whiten … [Read more...]
