Technical Guidance on Nickel

January 2017

What is it?

Nickel is an abundant metal. It is often combined with other metals to make alloys with increased hardness and resistance to corrosion. Nickel plating is widespread in decorative applications to give bright and shiny surfaces.

Potential health hazards

Many nickel compounds are carcinogenic, mutagenic and/or toxic to reproduction. In metallic components or components with metal plating, nickel may migrate from the parts and cause skin irritation. Some consumers may be more vulnerable to nickel allergy. It is also one of the most common types of skin allergy in Europe.

Commonly found in:

Fashion jewellery and watches e.g. ear rings, watch straps and wrist-watch cases; metal components in apparels and footwear such as snaps, metal buttons, zippers, eyelets, etc.
