Tonio Borg, the European Union's commissioner for health and consumer policy, explained Europe's stance of leading by example.
The ban, which will take effect immediately is an example of how much animal welfare means to Europe.
The European Union had completely banned animal testing of finished cosmetic products in 2004. Four years back, the second ban on animal-tested ingredients became effective.
"Europe's idea is to put more pressure on other parts of the world to end animal testing, but the science doesn't match that political timetable," said Colin Mackay, a spokesman for Cosmetics Europe, a trade association.
Mr. Borg said that Europe is committed to the cause of developing alternatives to testing cosmetics on animals and will lead by example of "responsible innovation in cosmetics without any compromise on consumer safety. "
