Can we have a put up a wiki with explanations of common ingredients?

I'm researching local detergents and I'm finding ingredients I'm unfamiliar with. Google turns up wikipedia pages not pertaining to detergents specifically. Some I found:

• Polycarboxylates
• Zeolites
• Phosphonates
• Citral
• Citronellol
• Coumarin
• Terpineol
• Limonene
• Amyl Salicylate
• Tetramethyl Acetyloctahydronaphthalnenes
• Butyiphenyl
• methyipropional
• Benzyl salicylate
• Geraniol
• Linalool
