anyone heard of this preservative

[Guest guest]

Came across this today while searching for something else:

http://www.lanaturale.com/preservative.html

<!--SNIP-->

This preservative is a patented combination of olidinyl Urea, the most

active member of the Imidazolidinyl Urea family of preservatives, and

Iodopropynyl Butylcarbamate (IPDC). It is manufactured by a large US

company, active in the chemical, pharaceutical and cosmetic area.

Anyone heard anything good or bad on it?

Thanks,
