  • Contains an antiseptic to protect wounds from infection

    CETRIGEN contains cetrimide, a well known antiseptic compound with antibacterial properties that inhibits the growth of bacteria in the wound and helps to prevent re-infection. Infection is a risk to any wound, no matter how minor, and if it becomes established in a wound it can delay the healing process and lead to more severe or additional problems like scarring and proud flesh.

  • Contains two powerful insect repellents

    DEET contained in CETRIGEN is regarded as one of the most effective insect repelling compounds available. DEET acts by creating a shield of repellent vapour as it evaporates. This shield confuses insects so they can’t locate the animal to land on. Di-N-propyl isocinchomeronate is also an effective insect repellent and works with DEET to create a stronger barrier. These two insect repellents provide effective protection for wounds to prevent them from damage due to insects.

  • Registered for use on all animals

    CETRIGEN’s broad species application means that it is a versatile treatment option for all animals. This means there is no need to keep multiple products on hand to treat different animals in multiple species households. CETRIGEN can be safely used on all domestic pets and farm animals.

  • Contains a purple dye

    CETRIGEN is sometimes known as purple spray due to the unique bright purple colouring of the product. A purple dye is included in the formulation so that the area treated can be easily identified to ensure full coverage. The dye will remain intact on the wound under most conditions so that treated areas can be quickly identified each day.

  • Convenient presentation

    CETRIGEN is available in a 100g aerosol and a 500mL trigger spray. Two practical presentations to suit a wide variety of situations and uses. The trigger spray applicator is noiseless and is also adjustable to provide various spray patterns to enable adequate coverage of the area being treated. The aerosol presentation does not contain compounds that are harmful to the environment and comes in a conveniently sized robust can.

  • How much do I spray on the wound?

    The wound should be sprayed lightly over the entire affected area, however any run off should be wiped away. 

  • What is CETRIGEN for?

    CETRIGEN is an antibacterial spray with added insect repellents. It is formulated for the treatment of superficial cuts and wounds in all animals. It assists in drying the wound, preventing bacterial infection and making the wound less attractive for flies. 

  • Why is CETRIGEN purple?

    CETRIGEN (‘purple spray’) is a bright purple colour to enable you to know exactly where you have sprayed it on the animal and to allow rapid assessment of how many and which animals you have treated.
