Parabens

Parabens are a group of chemicals commonly used as preservatives found in cosmetics. They prevent the growth of yeasts, molds and bacteria and preserve the shelf life of a range of everyday products including skin moisturisers, shampoos, conditioners, soaps, toothpastes, antiperspirants and deodorants, sunscreens, make-up and pharmaceutical products that include topical skin preparations.

One scientific study reports that parabens were found in samples of breast tumors. The validity of this study’s conclusions has been debated in the scientific literature. Nevertheless, this study has fueled the belief that parabens in underarm deodorants or other cosmetics migrated into the breast tissue and contributed to the development of the tumors. However, no causal link with cancer has ever been proven and so far there is no scientific evidence to support any link with any form of cancer.

Sodium lauryl sulfate is a surfactant widely used to make products foam or lather.

A number of health concerns about SLS have been raised in published reports. These studies indicate that SLS may cause a number of skin problems (for which the non-specific term is dermatitis), with some people being affected more than others

Synthetic Colors

Whether synthetic colors are completely safe or mildly damaging in the long run is unknown. Since they serve no useful purpose, they are best avoided.
