  2. Forgive my second intrusion, while your blog has indulged me with the origin of the several ingredients that go into Pretty: Limonene hailing from the peels of citrus, Ethylhexyl Methoxycinnamate seeing residue from sunscreens, and Citral being from plants as a oil. I am still curious, I don't recall seeing Ethylhexyl Methoxycinnamate's usage in Pretty so does it really need to be in Pretty despite it's cons?

  3. Very cool and interesting, I know more about perfumes now, but I think you forgot to mention butyl mercaptan, or "skunk spray". Is it really necessary to add this to perfume since they have to extract it from skunks? Is there a more natural way of adding a oil to perfume to make the scent stay?

  4. I don't use perfumes often the scent tends to nauseate me so I can't be around it too much, that said I don't actually read the ingredients in perfumes because it's usually pointless, overall the website was good, and the information was relevant to the topic and it's benefits and health hazards were clearly pointed out. :)
