What is the ';e'; printed on some products (like shampoo, cosmetics, and on my shortbread cookies?)?

It's not exactly an ';e'; but it looks like one and I've noticed it on several different products I have in my home. Is it some sort of international trade sign?What is the ';e'; printed on some products (like shampoo, cosmetics, and on my shortbread cookies?)?
That mark is on a lot of commonly used products such as shampoo, hand soap and a lot of other items that you can find in your home. I am not really sure of what it is. I think that you should try searching the web on yahoo of wikipedia for some answers. I hope that it helps and you find what your looking for.
