Parabens

In small concentration parabens are absolutely safe, and here the unenviable reputation they are obliged to the research of the British scientists conducted in 2003. By its results parabens have connected with developing of tumors. However later all data recognized as nekorrekty, and researches had had denials with serious proofs that small amount of parabens does not bear harm for organism.

This substance belongs to surface-active, it perfectly removes fat and salt from skin. It is considered that in high concentrations can cause irritation in the people sensitive to component.
According to researches, sodium lauryl sulfate is safe at short-term contact with skin with the subsequent plentiful washing by water. By the way, substance cannot get in cells of human body because of the large size of molecules therefore it is perfectly washed away.
Formalin and urea
These are so-called donors of formaldehyde, as a result of their use formaldehyde which works against microbes is formed. The quantity of these components in cosmetics is strictly limited therefore it is not dangerous even to the most sensitive skin. However, if you noticed for yourself tendency to allergic reactions, then better just in case refuse use of cosmetics with these components in structure.
