Legal analysis: if you produce laundry detergent and detergent yourself, if you don't sell it to the outside world, you won't violate any existing laws and regulations in China. I produce my own laundry detergent and detergent, and I intend to sell it to the outside world. Business license, tax registration certificate, trademark registration certificate, environmental assessment feasibility report, detergent production license (laundry detergent does not need a production license) and product quality inspection report must be obtained according to law.

Legal basis: Article 13 of the Trademark Law of People's Republic of China (PRC), a trademark that is well known to the relevant public. If the obligee thinks that its rights have been infringed, he may request the protection of a well-known trademark in accordance with the provisions of this Law. A trademark applied for registration on the same or similar goods is a well-known trademark copied, imitated or translated by others, which is not registered in China. It is easy to cause confusion, so it is not registered and prohibited to be used. Where a trademark applied for registration on different or dissimilar goods is a well-known trademark registered by others in China, misleading the public and possibly harming the interests of the registrant of the well-known trademark, it shall not be registered and its use shall be prohibited.
