Wellcap® Thymol is high active loading nano-sized particle designed to prolong antibacterial activity of free thymol by the nano-encapsulation technology. Thymol is phenolic monoterpene extracted from essential oils of different plants such as Thyme or Oregano which exhibits strong antimicrobial effect. However, activity in oral cavity of thymol is rapidly lost. Due to its low water solubility, alcoholic solution is chosen to render formulation and also limits usage of thymol. Wellcap® technology overcomes these limitations. Wellcap® Thymol provides more stability and dispersibility in water with high loading capacity.
