Lately, looking at some herbal products, I saw that many creams and tricks to be marked without parebeni.
From there the will to understand why this term is highlighted. Do not think that parabens are toxic?
premise that philosophy is that if ONE THING YOU CAN NOT SWALLOW WITHOUT SUFFERING DAMAGES, EVEN LESS IS BETTER THEN SPALMARSELA upon (our skin absorbs all the substances it comes into contact, then it's like the swallows). But try to be objective anyway.
First we must say that parabens are many and the main ones, or at least those that examine here are four: Methylparaben, Ethylparaben, Propylparaben, Butylparaben.
are most widely used in cosmetics such as creams, deodorants, shampoo, but maybe not everyone knows, are also used as additives food.
are preservatives and fungicides. But
briefly analyze one by one.
methylparaben (E 218)
paraben From the first, there may be a bit 'of contradictions, but it seems that this anti-irritant and antibacterial agent is considered a safe substance.
Despite this, however a small group of people have shown allergic reactions to this drug even though pairs like the one for those with sensitive skin.

Ethylparaben (E 214)
paraben Of this you have very little information around, but seems to be similar to the level methylparaben toxicity, ie little or absent.
Propylparaben (E219)
This preservative, however, is another story than the previous ones.
It is easier for this substance is irritating, and can particularly affect the eyes, skin, respiratory and intestinal tracts through, respectively, ingestion and inhalation.
addition, together with butyl paraben, studies have shown a potential risk to male fertility because it seems that both interfere with the reproductive cycle with the elimination of the sperm.

Butylparaben (E 216)
More or less the same as shown above, propylparaben.
Butylparaben
However, please note that a study of tissue taken from women with breast cancer, found in 18/19 (the information on these two data range) of 20 samples, the presence of parabens. This probably can not prove a link between breast cancer and parabens but it certainly shows that they are accumulated in our bodies, and thus not ejected. This is not a good sign, especially as these preservatives may cause a slight impairment of the endocrine system.
As usual, when in doubt, I prefer BEWARE with parabens from deodorants.
