    • Toxicity of coal tar
      A review of the epidemiologic literature confirmed statistically significant associations between hair dye use and development of several types of cancer although the authors concluded that the evidence was insufficient to determine that the hair dyes had caused the cancers (Rollison et al., 2006). A separate study found that women who used hair dyes especially over extended periods had an increased risk of developing non-Hodgkin's lymphoma (cancer of the lymphatic system) (Zhang et al., 2008). However, there is conflicting evidence, with other research suggesting no strong association between cancer and hair dye use (Takkouche et al., 2005).
      Coal tar has also been associated with cancer of the lung, bladder, kidney and digestive tract (Bonner et al., 2005). Pyridine, a coal tar constituent, has been linked to neurological damage. Effects include emotional and sleep disturbances, as well as loss of coordination (Pinsky and Bose, 1988).
      •    P-Phenylenediamine
      Commonly found in hair dyes, this chemical can damage the nervous system, cause lung irritation and cause severe allergic reactions. It's also listed as 1,4-Benzenediamine; p-Phenyldiamine and 4-Phenylenediamine (Catherine, 2007).
      •    Isopropyl Alcohol
      This is a solvent and denaturant (poisonous substance that changes another substance's natural qualities). Isopropyl alcohol is found in hair color rinses, hand lotions, and many other cosmetics. This petroleum-derived substance is also used in antifreeze and as a solvent in shellac. According to A Consumer's Dictionary of Cosmetic Ingredients, inhalation or ingestion of the vapor may cause headaches, flushed skin, dizziness, mental depression, nausea, vomiting, narcosis and coma. (De Felice, 2006)
      •    Imidazolidinyl Urea and DMDM Hydantoin - These release formaldehyde into the body. It is found in cosmetics such as nail polish, eyelash adhesive and hair dyes. It can irritate the respiratory system, cause skin reactions, trigger heart palpitations, immune system toxicity, and cancer in humans. Exposure may cause joint pain, allergies, depression, headaches, chest pains, ear infections, chronic fatigue, dizziness and loss of sleep. It can also aggravate coughs and colds and trigger asthma (Scheman, 2000).
      •    Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) - SLES are used more widely as one of the major ingredients in cosmetics, hair conditioner and about 90% of all shampoos and products that foam. According to the American College of Toxicology, both SLS and SLES can cause malformation in children's eyes, and damage to the immune system, especially within the skin. Skin layers may separate and inflame due to its protein denaturing properties. Research has shown that SLS, when combined with other chemicals, can be transformed into nitrosamines, apotent class of carcinogens, which cause the body to absorb nitrates at higher levels than eating nitrate-contaminated food (Scheman, 2000).
      According to the ACOT,"SLS stays in the body for up to five days..." Other studies have indicated that SLS easily penetrates the skin and maintains residual levels in the heart, the liver, the lungs and the brain.
      •    Nanoparticles
      Tiny nanoparticles, which may penetrate the skin and damage brain cells, are appearing in an increasing number of cosmetics and sunscreens. Most problematic are zinc oxide and titanium dioxide nanoparticles, used in sunscreens to make them transparent (Catherine, 2007).
      2.4    Heavy Metals Found In Cosmetics
      Some heavy metals can be found in cosmetics. Lead may appear in products as a naturally occurring contaminant of hydrated silica and lead acetate is found in some brands of hair dye. Brain-damaging mercury, found in the preservative thimerosol, is used in some mascaras (Ruud, 2003).
      2.4.1    Lead (Pb)
      Lead is a chemical element in the carbon group with an atomic number 82. It is a soft malleable metal which is regarded asa heavy metal and post transition metal (Liu et al.,2008).

      CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1 Background of studyCosmetology which include nail and hair care has become a lucrative profession. (Halliday-Bell et al., 2009). The use and application of cosmetics have been shown to have some effects on the human system. There are about 9000 chemicals ingredients found in cosmetic products (Kersemaekers and Roelveld, 1995). Nail and hair care users have daily contact with cosmetic products and are therefore routinely exposed to a wide range of chemicals by inhalatio ... Continue reading---
