NEW AND IMPROVED METHOD

Today, I realised how ambiguous and inaccurate my past method was...so here is my new method.

Hypothesis: Harmful ingredients such as Toluene and Formaldehyde have an impact on the durability of nail polish.
Aim: To find out the impact of harmful ingredients on the durability of nail polish.
Materials: Two nail polishes that do not contain Toulene and Formaldehyde, two nail polishes containing Toulene and Formaldehyde, Silicon Carbide abrasive paper, tape, block of wood, aluminium foil, stopwatch, q-tip, scissors, ruler

Risk Assessment:

Identify

Assess

Consequences

Prevention

Inadvertently inhaling Toluene. (Harmful to health)

Moderate risk.

Causing symptoms such as tiredness, confusion, weakness, drunken-type actions, memory loss and causing liver damage and skin irritation. In high levels, affecting the kidneys.

Carrying out experiment in a well-ventilated room while attempting to not inhale heavily. Wearing a mask.

Inhaling formaldehyde.

Moderate risk.

Causing symptoms such as watery eyes, headache, burning in the throat, and labored breathing.

Carrying out experiment in a well-ventilated room while attempting to not inhale heavily. Wearing a mask.



Method:
1. Tape aluminium foil onto a flat surface in room temperature (25°C)
2. Apply one layer of one nail polish containing Toluene and Formaldehyde onto the aluminium foil.
3. Time the duration for the polish to dry onto the foil.
4. Record observations and results.
5. Tape abrasive paper against a block of wood.
6. Rub the abrasive paper against the foil
7. Observe the duration and resistance until it begins to peel or chip and record results.
8. Repeat steps 2-7 using the three other types of nail polish.

My independent variable would be the nail polish's ingredients. The dependent variable would be the duration of the nail polish applied.

So...I got three different brands of pink nail polish. They're not necessarily the same shade of pink, but I spent ageees trying to look for the exact same shade...but I failed. ): But it is still pink so...

I just did a bit of research on harmful nail polish ingredients and I found this:

Many manicure and pedicure enthusiasts cannot stand the smell of the nail salon, but never stop to ask themselves if this smell might be linked to toxins that come free with each session of nail pampering. Before your next trip to the salon or to your beauty supply store to pick up something that will make your nails shine, consider the downside to the fumes you will be breathing in during the entire treatment and the plastic coating seeping into your body through your nail bed.

It is reported that almost all brands of commercial nail polish contain toluene and formaldehyde. Many still contain Dibutyl Phthalate, although the European Union banned all pthalates from all of their cosmetics.

Here are a few facts about these common toxic nail polish ingredients:

Toluene

Toluene is a human reproductive and developmental toxin. It may affect the nervous system with symptoms like tiredness, confusion, weakness, drunken-type actions, and memory loss. It is thought to cause liver damage and skin irritation. In high levels it may affect the kidneys. Toluene has been linked to birth defects in laboratory animals.

Formaldehyde

Formaldehyde is a carcinogen and a common indoor air pollutant because its resins are used in many construction materials. Formaldehyde has caused cancer in the nose and throats of lab animals. Inhaling the fumes can result in watery eyes, headache, burning in the throat, and labored breathing.

Dibutyl Phthalate

Phthalates are used to soften plastic, and are known to affect hormone function. Studies have linked phthalates to early puberty in girls and low sperm counts in men. Environmental groups claim phthalate exposure may contribute to the rising number of uterine problems in women and testicular cancer in men. It could also be one of the contributing factors to a rise in infertility in both sexes. Repeated and heavy exposure to dibutyl phthalate may cause nausea and/or vomiting, tearing of the eyes, dizziness, and headache. Long-term exposures may cause damage to kidneys and the liver. Pregnant women must consider that dibutyl phthalate may harm the developing fetus and the male testes.

If you have to choose a nail polish, try choosing a variety that contains the least amount of harmful toxins as possible. Always apply polish in a well ventilated area.

For the least risk, consider an alternative to the standard manicure with nail polish. First f ile, wash, and soak your nails. Then soften, clean, and shape the cuticles. Try soaking your nails in organic apple cider vinegar or simple warm water, and apply almond oil to the cuticle area. Buff with several fine grade buffing files (always in one direction, and only on dry nails) and admire your shiny, natural manicure. Moisturize your hands, and think about all of the toxins you just avoided. Beauty does not have to be dangerous.
