Controversial chemicals

Propylene glycol
This is a wetting agent and solvent used in make-up, hair products, deodorants, aftershave and toothpaste. It's also the main ingredient in anti-freeze and brake fluid and has, unsurprisingly, been known to cause allergic reactions.

Sodium lauryl/laureth sulphate
This harsh ingredient is found in toothpastes and shampoos, not to mention just about every personal cleansing product. In concentrations of only 2-5 per cent it can cause skin irritation and dermatitis, and has been reported to cause eye irritations, skin rashes, dandruff and allergic reactions. For SLS-free haircare, try Alterna (www.4alterna.com) and Daniel Galvin Junior (www.danielgalvinjnr.co.uk).

Formaldehyde
Formaldehyde is found in bubble bath, shampoos, moisturising lotions and many cosmetics. However this powerful chemical is a known carcinogen and a poisonous toxic substance. It readily penetrates the skin and can cause serious future health concerns.

Parabens
There are concerns that parabens, a preservative, may disturb hormones and that they have been found in breast cancer tissue. Much of the reported evidence linking parabens deodorants to breast cancer was unfounded (deodorants don't usually contain parabens as they tend to be preserved with alcohol). In the beauty world however, parabens has been extensively reassessed and found to be safe. For parabens-free beauty, try Trilogy (exclusive to www.beautique.com) and INA (stockist listed below).

Mineral oil
Mineral oil is used in many body lotions (baby oil is 100 per cent mineral oil) and coats the skin like a plastic wrap, so it can't breathe or release toxins. And allowing toxins to accumulate can result in premature skin ageing, acne and other skin disorders.

Petrolatum (petroleum jelly)
This is a cheap, heavy mineral oil jelly. It can be allergenic, does not absorb well and may clog pores. It smothers skin so it cannot breathe naturally and may also cause skin chapping and photosensitivity.
