This is not infringement. No one knows what your specific ingredients are. Even if your ingredients are exactly the same as your competitors, they can't do anything about it. You don't have their registered trademark. You can refer to the classic case, the dispute between Wang Laoji and Jiaduobao. Although Jiaduobao used Wang Laoji's formula, it didn't use Wang Laoji's registered trademark, and Wang Laoji couldn't win the lawsuit.
