Cosmetics contain many different kinds of chemicals, parabens, known hormone disruptors: evidence suggests they can mimic the female hormone oestrogen, and a lifetime of increased exposure to oestrogen is linked to a heightened risk of breast cancer.
Another troubling chemical is the antibacterial agent and pesticide triclosan, which is used in toothpastes, soaps, household cleaning products and body washes.
It belongs to the chlorophenol class of chemicals, which are suspected of causing cancer in humans and taken internally, even in small amounts, can cause cold sweats, circulatory problems and - in extreme cases - coma.
Also of concern are phthalates, a substance that gives our lotions that silky, creamy, texture, but which are also a 'plasticiser' used to make plastics flexible.
Certain phthalates are known carcinogens, and studies have suggested they damage the liver, kidneys, lungs and the reproductive system, as well as affecting the development of unborn baby boys.
The list goes on. Sodium laureth sulphate, a frequent ingredient in shower gels and shampoos, is a skin irritant; Propylene glycol, found in soap, blushers and make-up remover, has been shown in large quantities to depress the central nervous system to make it function less effectively, and aluminum in deodorants is linked to breast cancer by medical research.
