One Drop Only: History
Otto Müller and his Scottish son-in-law John Rorison hit upon the idea of manufacturing a medicinal mouthwash to be called Rorison’s Drop.
Müller and Rorison found the One Drop Only Chem.-pharm. Vertriebs-GmbH. After completion of the research and development work and extensive studies, the One Drop Only Mouthwash Concentrate is launched onto the market.
After almost 38 years, the portfolio is extended by a new product: The practical mouth spray is introduced to the market.
More product introductions follow, such as mouthwash, chlorhexidine and mint pastilles.
Name change: Nur 1 Tropfen® turns into One Drop Only® due to the increased international orientation
Packaging relaunch: in order to win the younger gerneration as our clients we trust in a young, fresh and attractive Design. Yellow turns blue.
The brands One Drop Only® PHARMACIA and One Drop Only® Naturals are added to our portfolio.
