There are clear environmental factors when it comes to choosing whether to use washable or disposable nappies. But what about the vast amount of baby bath lotions, shampoos and creams? Many - in fact most, contain ingredients that can not only irritate the skin, but may well have a hormone changing effect on humans, and are also pretty bad news for fish in the sea too.

Early in 2007 American environmentalist and scientist David Steinman, released results from laboratory tests on 1.4-Dioxane. This substance is a petroleum-derived contaminant considered a probable human carcinogen by the U.S. Environmental Protection Agency. It was found there were significant levels in well known American children's brands including Johnson's Kids Shampoo Watermelon Explosion (Johnson & Johnson) which had 10ppm. The Environmental Working Group has a database of US sold products it says are ‘safe' from harmful chemicals (http://www.cosmeticsdatabase.com/) and baby care products are included. They are also currently investigating what is in the products used by over 3,500 children under ten years to find the true state of toxins in our everyday washing routines.

You can find out about what chemicals are in bath products in general and many in baby bath products at http://www.chemicalsafeskin.co.uk/. But here are the worst offenders:Parabens - chemical, synthetic preservatives that enable a longer shelf life. Often called ‘methyl, propyl, butyl and ethyl'. Its been reported that these chemicals mimic the body´s own hormones and can have endocrine-disrupting action when they are rubbed into your body or washed down the drain into your drinking water. They can also influence sex change in fish.

Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) - surfectants used to make products foamy. They are often found in soaps and shampoos and can cause severe irritation. They are derivatives of sulpuric acid and have a drying effect on the skin. But look at your labels even on baby products, you'll find them.

Phthalates - chemicals mainly used in used in polyvinyl chloride (PVC) form to bring about malleability and softness. Testing on animals has suggested phthalates can cause reproductive defects and some research has shown early exposure can cause reduced testosterone levels in boys. The good news is there are some excellent baby toiletry ranges that deliberately omit use of such unnecessary chemicals.
