TCP Antiseptic Liquid provides powerful protection against infection in cuts, grazes, mouth ulcers, and sore throats. Its versatile antiseptic formula cleanses, soothes, and promotes healing for everyday first aid and oral care.
TCP Liquid Antiseptic is a clinically trusted, broad-spectrum antiseptic solution used to help prevent infection and relieve pain caused by minor wounds, sore throats, mouth ulcers, insect bites, and skin irritations.
Formulated with halogenated phenols and phenol, TCP provides powerful antibacterial, antifungal, and mild anaesthetic action. It’s a long-standing household essential for both first aid and oral hygiene, suitable for use by adults and children when diluted correctly.

| Mouth Ulcers | Dab directly on ulcers to promote healing and reduce discomfort. |
| Cuts & Grazes | Prevents infection in minor wounds and speeds healing. |

TCP’s key ingredients – halogenated phenols (0.68% w/v) and phenol (0.175% w/v) – kill germs by:
Damaging bacterial cell walls and stopping growth
Preventing infection by creating an unfavourable environment for bacteria and fungi
Providing mild local anaesthetic action to relieve pain and soreness
Together, these effects make TCP an ideal multi-use antiseptic for both skin and oral infections.
Different conditions require slightly different applications. Always read the label or leaflet before use.
