1. An organic chemical commonly found in cosmetics is dibutyl phthalate. It can be found in cosmetics such as nail polish or can be used as a fragrance in many other cosmetics.

2. Dibutyl phthalate is a phthalate ester which is a colourless oily liquid, and has a strong bitter taste, and a slight aromatic odor. The structure of dibutyl phthalate includes a benzene ring and two ester bonds attached to it.

The reason dibutyl phthalate is used in nail polish because is allows dyes to be dissolved in it easily and since it is also commonly used in the manufacturing of plastics, it prevents nail polish from becoming brittle, which would be an undesirable quality for nail polish to be. The benefits of using dibutyl phthalate in nail polish is it increases its resistance to chipping due to it’s flexibility. It’s slight aromatic odor allows it to be used in some perfumes.

3. Some health effects associated with the exposure to dibutyl phthalate include kidney and liver failure in young children, when a product containing dibutyl phthalate undergoes consumption (ie. sucking or chewing on) for prolonged periods of time, or may cause harm to a fetus and impair fertility. Also, since dibutyl phthalate can be absorbed into the skin, it has shown to reduce sperm count and cause developmental defects. There is also evidence that dibutyl phthalate may interfere with hormone functions.

4. The environment is impacted the most by the release of emissions directly into the environment during manufacturing and use of dibutyl phthalate. This impact has shown to increase the amount of dibutyl phthalate in the Great Lakes, among other bodies of water, which is a problem because dibutyl phthalate is very toxic to aquatic organisms.

...hanolamine derivatives are used more commonly in many cosmetics.

3. Diethanolamine is a nitrogen containing substance, and nitrosamines have been clearly identified as a carcinogen. Diethanolamine has also been proved to induce asthma, cause shortness of breath, or cause irritation of the eyes or skin. Diethanolamine mainly affects the eyes, skin and respiratory system. In mice, it has also shown to have a slow excretion rate from the urine, so it builds up in the liver and kidneys and there it may be metabolized into atypical phospholipids.

4. During the degradation of diethanolamine, nitrites are released into the environment, which is acutely toxic to aquatic organisms, and has a potential for bioaccumulation. But, due to a half life of around only a few weeks, it does not present a high risk to the environment otherwise, mainly affecting humans health.
