How to say "synthetic" in Japanese

• 人造じんぞうJLPT N2approx.Common
  no-adjectiveCovers the material sense of 'synthetic': man-made substances, especially imitations of natural ones. It stresses that something was produced artificially rather than obtained from nature, as with synthetic gems or fibers.
  これらの真珠しんじゅは人造じんぞうではなく本物ほんものです。↗

  These pearls are genuine, not artificial.
• 総合的そうごうてきCommon
  na-adjectiveNot used for man-made materials. It matches the abstract sense of 'synthetic' — formed by combining separate elements — as in the linguistic term for synthetic languages; its usual meanings are comprehensive, composite, all-round.
  彼かれも大人おとなになって、物事ものごとを総合的そうごうてきな視野しやで見みられるようになった。↗

  As he grew up, he learned to put things in perspective.
• ケミカルCommon
  prenominal modifierA katakana loanword that simply means 'synthetic'. It is heard most often about man-made fibers, fabrics and similar materials, in everyday speech and in product names and descriptions.

Use 人造 for man-made imitations of natural substances, 「ケミカル」 as the everyday loanword for synthetic materials, and 総合的 only for the abstract sense of combining elements, as in linguistics.
