Recently, many prominent scientists have expressed the view that parabens in cosmetics - it's bad, but at the legislative level can not impose a ban on their use.Large cosmetic companies are trying to solve this problem and to gradually eliminate the use of preservatives in their products.
So what parabens in cosmetics, it is really dangerous, or simply unwound topic for discussion?
called parabens chemicals which due to their properties prevent premature appearance of fungi and bacteria.They are used not only in cosmetics but also in food and medical industries.Some parabens occur even in nature, but in cosmetics parabens - are synthetic products.
In many developed countries, the number of parabens in cosmetics is strictly regulated.For example, parabens such as propyl - methyl -, butyl -, ethylparaben and their various isoforms allowed in an amount not greater than 0.4% and should be only paraben in the product.If you use a mixture of parabens, its concentration should not exceed 0.8%.There is the opinion of some experts, it is usually about 0.2% of their in cosmetics is enough.
What is the danger of parabens?
In the past few years, a more statements that they are endocrine disruptors.Therefore, in Europe it decided that propylparaben used in cosmetics should rarely, its allowable concentration to halve, the same requirement applies to butilparabenam.
parabens have estrogenic effects.Therefore, the use of products in which they are present, should be restricted to people who have a contraindication to the use of estrogen.Especially careful you have to be pregnant women, as excess estrogen can adversely affect the outcome of pregnancy.
Some scientists refute this claim and prove that such an effect is only substances that enter the body along with food and essential parabens harmless.
At constant use prabenov they accumulate in the body that can contribute to the development of cancer of the breast, uterus, ovaries in women and testes cancer in men.But this is just the opinion of scientists, is a direct causal link between the use of parabens in foods and in cosmetics, with the occurrence of cancer has not been established.
parabens in cosmetics may slightly increase the negative impact of the sun.Medications which contain methylparaben, when applied to the skin, may cause premature aging and even lead to DNA damage.This occurs due to the reaction of methyl paraben with ultraviolet rays.Also, application of the agents that comprise propyl, metilparbeny may cause various skin irritations and even contact dermatitis, and allergic reactions.
But do not just stop using products that contain parabens.All the above figures are only the opinion of experts, but their is no scientific confirmation or refutation of contrary yet.
According to official science, parabens are almost non-toxic and easily excreted.For healthy people, they are harmless and only in very rare cases may cause allergic parabenovuyu.For such people are released without parabens cream.
Despite all that parabens in cosmetics provide sustained its storage, which does not violate its properties and quality.
They are present in almost all cosmetics, but also in many foods and medicines.Since currently do without preservatives is practically impossible, scientists are looking for an alternative to parabens.But while it is not, are being developed to create a preservative on renewable raw materials.
