You want to promote new business with a different name., so here you can choose one of the following options.
Either create two sub brands and linked them to the corporate brand name. Your business name should be there for the repu and better identity. Like;
Nestle is the corporate brand and sub brands are in different lines as
Nestle Cerelac, Nestle Kitkat, Nestle Pure Life and etc.
