What permission and licence would be required to make lux soap?

To manufacture Lux soap, you would typically need a manufacturing license from the relevant health and safety regulatory authority, which ensures compliance with safety and quality standards. Additionally, you may require a business license to operate legally in your location. If using proprietary formulations or branding, obtaining permission from the trademark holder (Unilever, in the case of Lux) is essential to avoid infringing on intellectual property rights.
