Chemistry of Nail Biting Products

Post image for Chemistry of Nail Biting Products

Chew-Chew says…How do nail biting and thumb sucking prevention products like Mavala work?

The Right Brain responds:

Products like Mavala that are designed to keep you from putting stuff in your mouth are based on one simple principal: if things taste really, really, really bad you won’t WANT to put them in your mouth. To that end, these products employ Bitrex the trade name for denatonium benzoate, which is billed as the “bitterest substance on the planet.”

Bitter is a choice

Even the tiniest spec of denatonium benzoate is distasteful but not toxic.  That’s why it’s widely employed in  nail biting, thumbsucking, and “don’t chew this” products for pets. Yes, if you get a mouthful of this stuff you’ll likely to be heaving your guts up, but it won’t kill you.

In the case of Mavala, the anti-bite agent is formulated into a nail polish-like base consisting (primarily) of Ethyl Acetate, Alcohol, PVM/MA Copolymer, Phthalic Anhydride/Trimellitic Anhydride/Glycols Copolymer, Butyl Acetate, Acetyl Tributyl Citrate, and Sucrose Octaacetate. This provides a durable coating that provides a slow release of the bittering agent that can last for several days.

Why Does Nail Polish Turn My Nails Yellow?

Post image for Why Does Nail Polish Turn My Nails Yellow?

Sue says… I was wondering why wearing nail polish turns my nails yellow? Also, is there anything we can do to prevent that?

The Right Brain’s polished response:
It’s true, nail polish can turn your nails yellow. Why? There are a couple of reasons:

Color reaction

Some of the darker colored polishes can stain nails due to a chemical reaction between the colorant and the nail plate. This reaction is hard to predict because it doesn’t happen for everybody for every dark color. It can also take a few days to a few weeks to occur.

Formaldehyde

It’s also possible that formaldehyde (one of the ingredients in many nail polishes) is causing the problem. This chemical can react with the keratin protein in your nails and make it brittle and yellow.

Medical issues

Finally, if your nails are really yellowed and disfigured, you may have a nail infection or a more serious medical condition known as Yellow Nail Syndrome.

So what can you do about it? Read on!

Tips for non-yellowing nails:

  • Don’t try to scrape off the stained area because it will damage and weaken the nail.
  • Stay away from dark colors (which will greatly reduce your fashion options)
  • Wear a base coat to protect your nails from staining (this makes sense to us)
  • Look for nail polishes that don’t have formaldehyde on the ingredient list. (There’s no guarantee that this will work but hey, it beats this next tip we found from one of the nail polish companies from which is…
  • Wear gloves (now there’s a practical idea!)
  • Stop wearing polish and wait for your nails to grow out. (Also not too practical, this could take 4 to 6 months.)
  • Soak your nails in 1/2 cup of water and juice of one lemon for up to 15 minutes, once a week, according to Sally Hanson. (We’re skeptical if this works but you can always add some sugar and just drink it as lemonade.)
  • Buy only yellow shades of polish so you can’t tell if your nails are stained or not. (Sorry, just kidding on that one.)

The Beauty Brains bottom Line:

Nail polish can stain your nails yellow but by choosing the right shades, using a protective base coat, and drinking a lot of lemonade while wearing gloves, you should be able to control the problem.

Don’t want to break a nail? Give your nails the attention they deserve.

Your nails end up taking the brunt of daily wear and tear. It’s no wonder why they sometimes get cracked and brittle. There are several easy steps you can perform from home to strengthen your nails and get them looking healthy and strong.

  • Whiten your nails (similar to whitening your teeth)
  1. Mix one teaspoon of baking soda, coarse salt and lemon juice together with enough hydrogen peroxide to make a thick paste.
  2. Leave the whitening paste on your nails for approximately 20 minutes.
  3. Wash the hands with warm water and rub olive oil over your nails to help restore healthy nail texture and shine.
  • Cod liver oil – I know it may sound rather repulsive at first, but make it in orange and mint flavor for a refreshing scent.
  1. To moisturize nails on a weekly or daily basis try using cod liver oil. It’s cheap, easy, and available at almost any drug store. I prefer the orange flavor.
  2. Rub a dab of cod liver oil onto each nail and massage into the nails. Allow the oil to set in for about five-ten minutes and then rinse off with warm water.
  • Sought out polish- when you need a quick fix hit the store and pick up OPI nail envy. The Nail Envy line was created to improve and strengthen the fingernail with several options for different nail types.

The Mayo Clinic suggest taking some precautionary measures to give your nails some extra care:

  • Don’t abuse your nails. Don’t use your fingernails as tools to pick or pry things apart, you could be causing some serious damage.
  • Protect your nails. Wear cotton-lined rubber gloves when using heavy cleaning soaps ro chemicals. This is usually half the cause of damaged nails.
  • Don’t bite your nails or pick at your cuticles. Doing so can damage the nail bed. Even a minor cut alongside your nail can allow bacteria or fungi to enter the nails bed and cause infection. Your nails grow slowly, therefore an injured nail can retain signs of injury for several months.
  • Moisturize frequently. Nails need moisture just like our skin does. Apply a moisturizer each time you wash your hands or are use harsh chemicals.
  • Make time for routine nail maintenance. Trim fingernails and clean underneath the nail on a regular basis. Never pull off hangnails! Pulling off hangnails usually results in ripping living tissue. Instead clip hangnails off, leaving a slight angle outward.

Soon enough you’ll be showing off your nails to everyone!
