Methylchloroisothiazolinone

This is pretty random, but:

The other day while soaking in the shower, I was lathargically staring at the back of the shampoo and bodywash bottles when I noticed some strange chemical ingredients. I think I saw one of the longest words I have ever seen:

Methylchloroisothiazolinone.

What is that??? And why does it need such a long word? What do the parts of that word even mean? Wikipedia defines it: "Methylchloroisothiazolinone is a preservative with antibacterial and antifungal effects within the group of isothiazolinones." Well now we know, not that you or I care..

Update

To begin with, I apologize to the whole like two readers of my blog for taking so long to write a new post. Since August, my life has been basically consumed by soccer and school, and newly football. As an update on some of those subjects, our soccer team is having a dreamteam year (right now 12-2), and definately has the potential to win the New Mexico state championships. And recently, I began kicking for our football team as well! Hopefully I can be of some value to them...

Again, I apologize for taking forever to write; I will try hard to post more often..
