When Unilever brings out a anticeptic product with a proven active ingredient do they need to get approvals from labs, independent tests etc to prove it works? No because it's already been tested.
If the the technology is already proven but not patented anyone can launch a product in the matter of months with sufficient resources, that's the issue I'm concerned about.
The issue i have re Stayzon is not how big their sales are as they are a tiny company but how they have a product with the same technology as Zoono.
If they are licenced then that is fine, if not i have an issue with that.
One of the primary reasons i invested in Zno is because they have a unique range of products, if they have no protection of those products i will sell.
