Titanium Ring Band
Nickel is a metal used in many alloys. The use of many metal objects that we are almost in daily contact with it. The primary cause of contact dermatitis in Europe is due to nickel. This allergy begins in adolescents and young adults, reaching (for now) more common in women than men. To reduce these risks, there are in Europe, legislation limiting the amount of nickel release from objects in contact with the skin (European Directive 2004/96/EC). Usually, sensitization to nickel occurs when the metal is in contact with the skin is inflamed and most of the time this event occurs after the ear piercing. Women who have pierced ears are 10 times more likely to be sensitized to nickel that women who have not had. In humans, education is often linked to handling objects in nickel, but the mode of piercing may reverse things. In general, the allergy persists throughout life, it is necessary to prevent physicians and surgeons of this sensitization to nickel (which must be proved) for the use of medical devices can release nickel (stents, IUD Essure ® , etc. ). . Sweat can dissolve and release nickel in a metal and that even through thick clothing, a varnish or a plaster. You can easily trigger an allergy when the weather is hot and sweating is important. Indeed, just very small amounts of nickel in contact with the skin to produce a reaction that can occur when these objects are manipulated (cashier) or left in a pants pocket for such a long period of the day. Stainless steel contains nickel, but it is strongly related to steel and there is no generally nickel release and therefore no allergic reaction. And wearing jewelry made of stainless steel is not a problem. Some earrings are said to be hypoallergenic, but they can cause a reaction of intolerance, as they are made of metals that can release nickel. Nickel and palladium: palladium allergies are often associated with nickel allergy, but the subjects reacted to patch tests do not necessarily trigger reaction to palladium content in some jewelry and metal prostheses. kitchen utensils, appliances, needles, scissors, thimbles, door handles: the places of contact with the skin should be plastic, titanium ring band or stainless steel ("stainless"). We must use such glasses whose frames are made of plastic or titanium. It is banned in Europe to manufacture or import and sell products containing metallic nickel (listed below), unless the nickel is released under,. If these products are covered with a material other than nickel should not, for a period of normal use at least 2 years, releasing more than 0. 5 g / cm ² / week of nickel. Are not affected by this Directive, spectacle frames, coins, mobile phones, medical devices. A simple test reliable enough and can measure whether the amount of nickel is greater than 0. 5 g / cm ² / week of nickel. It uses a chemical, dimethylglyoxine, which takes a pink color in contact with the nickel if released in excess. Unfortunately, it is hard to believe that this regulation is respected as a Danish study published in 2009 showed that the test was positive in dimethylglyoxine (release of more than 0. 5 g / cm ² / week) for more than one accessory dress or costume jewelry out of 5 (22%) sold in 36 stores in Copenhagen. Objects (cheap) in question had been purchased from "hawkers" in clothing stores and shops owned by foreigners. .
