Beauty products can contain carcinogens, studies warn
The variety of shades of lipsticks and nail polishes or long duration of shampoos and creams can have a price: the chemical composition, it is often unhealthy. New research from Unicamp developed a technique for detecting, in seconds, the components of some beauty products in the Brazilian market, the third largest in the world with sales of R$ 85 million in 2012, according to the Brazilian Association of Personal Hygiene , Perfumery and Cosmetics. The survey results pointed to the existence of cosmetic allergens or even potentially carcinogenic and has been published in the scientific journal "Materials".
The marks were not disclosed by the researchers, but they warn that three nine investigated glazes contain high rates of SUDAM III dye that can cause cancer. In the case of lipsticks, they oxidize (or lost their properties) before the end of the validity period, which may have occurred, according to scientists, due to contact with saliva. And samples eyeliner were all potentially causing irritation or infection.
- I discovered I had allergies to cosmetics soon as I first used mainly for the eye, as the pencil. Soon after that step is scratching a lot and it seems that cried hours. Even those who say they are hypoallergenic causing me trouble. It is very difficult to find something that does not annoy me, even the most expensive brands and imported - the doctor says Juliana Keller.
The pharmacist Diogo de Oliveira, coordinator of the study, explains that scientific advancement helps regulate the cosmetic composition. He cites parabens, whose use was widespread, but lost momentum after the publication of studies identifying the toxicity of molecules of class. According to Oliveira, the labels disclose the composition but not the quantity of the substance, and it is difficult to unravel the consumer get the information.
- When dealing with dyes, they usually come in codes such as Color Index (CI). Each of the codes CI concerns a different dyestuff, which hinders the rapid identification by any consumer, necessitating the table lookup of these substances. For example, the SUDAM III study is on the identification label or as CI26000 Solvent Red 23 - exemplifies.
Lead present in cosmetic
This is not the only study warning of cosmetic substances. The University of California and the School of Public Health Berkeley recently released a survey in which 32 lipsticks and gloss of the American market, had half lead in amounts greater than allowed in the country. Already in ten tags, which have not been identified, there was an excess of chromium, a suspected carcinogen, in addition to manganese, titanium and aluminum. Another study published last year by the Department of Chemistry, Federal University of Minas Gerais shows that 22 types of lipsticks in the Brazilian market, just one, of French origin, not contained lead. The subject is so popular that in the U.S., was established the NGO "Campaign for Safe Cosmetics". In partnership with research institutes, they have created a database of product analysis as a way to pressure companies and governments.
One of the messages of the NGO is to be aware of some substances described on the labels. The Consumers Association (Protest) has released research that give important tips: avoid sunscreens benzophenone-3 with a chemical filter with allergenic potential; baby shampoos with methyldibromo glutaronitrilo also an allergen, and glazes with dibutyl phthalate, the banned substance Europe, and nitrotoluene, toluene and furfural, carcinogenic compounds.
- In general, the substances are more problematic preservatives and pigments. Of course it depends on the exposure to say that it will cause cancer, is more common to have allergies - says the coordinator of chemical tests of Protest, Carlos Confort, remembering that there are substances banned by ANVISA. - No company was outside the law, but they have the technology to make products that give more attention to health. And is the responsibility of the consumer to have to look over the label.
The results have yielded Protest signing a Condura Adjustment Term (TAC) in the case of businesses enamel, and are always sent to ANVISA, which in March limited the use of lead only to hair dye.
- Today I read the contraindications and try to buy brands hypoallergenic and more natural - tells the analyst documentation Mariana Barros, having developed rosacea, which are red patches on the skin with the use of base and blush.
Conservation and use inadequate
Besides the presence of chemicals sometimes harmful to health, how to preserve and use also directly influence the quality of the product and generally perform poorly, can bring some risks, such as infections and allergies.
Professor, Faculty of Medicine Uerj Spider Renata says missing evidence that substances in cosmetics are carcinogenic, so for her, the most important is to be aware of ANVISA certification and not stop doing sensitivity test:
- It is a very popular test, but until now I forgot and got the whole face red and burning once. Ideally, therefore, is to test the new product on a small area, such as the hand, before putting on the face or entire body - alert.
According to her, following the expiry date is important because the preservatives protect the product from bacteria and fungi. Moreover, sharing makeup and even enamel has its risks of contamination. Accessories manicure so not talking only sterilized.
Basic care is simple and efficient: Do not leave the product in direct sunlight, do not store anything wet and note whether the product was change in color, odor or texture. The doctor also gives a hint to search and product evaluation suggests www.belajuda.com.br site.
Enamel
In different studies were found carcinogens such as SUDAM III, nitrotoluene, toluene and furfural, and compounds banned in Europe, such as dibutyl phthalate. Brazilian law does not mention or concentration limits in the case of these compounds.
Lipstick and gloss
Can oxidize before the end of shelf life, perhaps by contact with saliva, so it's good to pay attention to the aspect of the product. Research has found lead, manganese, titanium, aluminum and phthalates in some brands, all considered toxic. The Protest rebuked the label of some packages which have letters too small to read.
Moisturizer and sunscreen
The Protest also found phthalates in some brands of moisturizer. Among the guards, the tip is to avoid those containing benzophenone-3, which can cause allergies. Remember that the application must be made 15 minutes before exposure and repeated every two hours. Should be used daily on the face, even on cloudy days.
Shampoos and dye
In baby shampoos, it's good to keep an eye on methyldibromo glutaronitrilo, allergen. Among the dyes, avoid ammonia also allergen and whose stench can bring discomfort.
Labels in general
Not all substances are described on the label, making it difficult to check. Also, the amount is not something apparent, leaving to scientific research pointing their values. Search natural products is one way to avoid allergies. To escape the dyes, they are identified by the acronym CI followed by a number.
