Phthalates are a group of chemicals commonly used in the production of plastics and as solvents in many consumer products, including synthetic perfumes. They help in dissolving and stabilising other ingredients, thereby making the scent last longer. However, growing research has linked phthalates to health concerns.

Phthalates are known endocrine disruptors, meaning they can interfere with the body's hormone systems, potentially leading to reproductive issues and developmental problems. Research has shown that phthalates, specifically di-2-ethylhexyl phthalate, binds to oestrogen receptors, increasing oestrogen levels in our bodies. Phthalates, preservatives and parabens enter our bodies through the skin—our largest organ—where levels can accumulate, causing concern.

This has led to an increasing demand for phthalate-free alternatives in the beauty industry, and specifically a demand for phthalate-free perfumes and phthalate-free colognes.
