My dictionary defines artificial as made or produced by human beings rather than occurring naturally, especially as a copy of something natural.
But since any manufactured substance can only be created from something that has natural origins, can anything simply be described as artificial?
Are we not restricted, in the use of the word artificial, to placing it as an adjective, in front of nouns? We talk, for example, about artificial fibres, meaning things like nylon, or polyester, which do not occur naturally as fibres as do wool or cotton. Similarly someone may have an artificial limb.
But placing a notice on a food package saying nothing artificial contained here I would suggest is nonsense, since everything in the world is either extracted, manufactured, or contrived through chemical process from a naturally occurring substance of some sort.
Can artificial be used alone without further qualification?
