Your vagina is one of the most absorbent parts of your body. That means they are very good at helping all kinds of chemicals enter your body, and often that they are pretty sensitive. You need a tampon that won't leak and is comfortable. Not one made with fragrances, dyes, chlorine, and pesticides. So, when you can, opt for products that are organic and free from other unknown and non-disclosed ingredients while still doing what they were designed to do (including when it comes to sex).
