They are used as preservatives because they serve to keep bacteria away. They are very cheap to produce, which is why many cosmetic brands use them.

They are very used so that the products acquire a more creamy texture or are more sparkling, some sensitive people show irritability in skin and eyes. The worst risk posed by these three compounds is that added to other components enhance carcinogenic effects (although the danger is not very high).

If one of these ingredients appears on the label, it is a cosmetic product to avoid.

3. Siloxanes

Siloxane is used to soften and soften cosmetic products. Although there is no definitive study, it is suspected that they alter hormonal functions and cause toxicity in the liver .

11. Pfelendiamine

It is a compound derived from anilines. It is used by its ability to color and its low cost so it is commonly found in hair dye. It appears as CI and a 5-digit code.

This ingredient is harmful in beauty products because in addition to causing irritation has been shown allergic reactions of asthma and being a compound derived from coal tar, is highly carcinogenic.
