You can restrict any user from creating a new product by following these steps:

- Go to:

Settings > in "Users" Select "Manage Users"

Select the user which you need to restrict him from creating a new product.

Select "Edit" then in "Inventory" Select "User" ((Do Not Select Administrator)) then click save.

..

Settings > User & Companies > Select "Groups"

Search for "Inventory / User" then Select it

Select "Access Rights" then Select "Edit"

In the table, you will see "product.template stock user" ..

Tick inside "Create Access" to allow users to create a new product or untick to restrict the user from creating a new product.

Hi, just a few notes:

1. I guess you meant 'ir.model.access.csv' file, not security.xml?

2. Check that the rule is applied through the interface in the debug mode:  Settings > Techical > Security > Access Control Lists > search for object 'product'

3. Make sure your user doesn't belong to any other user group, which has right for creating products (in the same list as above)
