Some of the most damaging chemicals found in cosmetics are:
-Mascara is a commonly used make-up product used by many women every day to enhance their eyelashes, in hopes of giving definition to the eyes.

Hair colour/ bleaching agents

When CFC’s, such as Methane, are released through an aerosol hairspray can into the air, solar radiation high in the sky breaks the compound apart. which cause harm to the ozone.
p-phenylenediamine
Hair dye
long term toxic effects on aquatic ecosystems. It diminishes the animal plankton population, alters fish behaviour and causes death in many aquatic species.
