You need to apply for a patent. What you develop yourself must be inspected by relevant departments, registered trademarks, etc., and can only be sold after approval for listing! Very troublesome. Besides, are you sure you have the conditions to produce it? Usually you apply for a patent and then wait for other companies to buy your patent. How can you produce it if you don’t have a company of your own? Also, are you sure that the laundry detergent you developed is innovative and valuable?
