Amongst the 'commonly found' ingredients, I found these two interesting; 'Diethyl Phthalatethe' and 'Cetrimonium Bromide'.
Interesting due to the fact that Alcohol is listed first, so percentage wise, this product contains more alcohol (which is an antiseptic) than the remainder of the ingredients. But Cetrimonium Bromide has also been added which is an antiseptic.
Diethyl Phthalatethe -- The addition of a small amount of DBP provides just enough "give" to make nail polish chip-resistant. When perfume fragrances are dissolved in either DEP or DMP, they evaporate more slowly, making the scent linger longer. They also find other niche applications in products such as adhesives and as solvents.
Cetrimonium Bromide - A cationic conditioning agent and antiseptic widely used in the pharmaceutical industry. Due to its high cost, it is rarely used in cosmetics. Adds shine.
