Phthalates and their derivatives are widely used in the plastic's industry. The ingredient is a plasticizer — it is what makes some plastic's soft and flexible such electrical wiring or certain types of PVC bottles.

Phthalates have been associated with causing hormonal disturbances, especially in young boys and males in general. There is increasing evidence that these chemicals may pose a health risk. Most recently there has been a strong trend against the use of phthalate containing plastic for use in children's products and toys. In the personal care industry, phthalates are most commonly used in nail polish and fragrance. Often fragrance manufacturers will use phthalate chemicals to give a longer lasting or time-release capability to their fragrance.

Unfortunately, it is usually impossible to tell whether phthalates have been used in the fragrance, as manufacturers simply list the word 'fragrance' or 'perfume' on cosmetic labels. There are no regulations requiring a full breakdown of a fragrance's ingredients to be listed on a cosmetic label. Spotting phthalates used in packaging is a lot easier. Look out for this symbol with the numeral 3 in the center of the triangle to quickly identify phthalate containing packaging. Check the label and packaging of any of your existing products to see if they contain phthalates.
