Forms a waterproof aluminium barrier for wounds and sensitive skin making it ideal for use after castration and dehorning. It also shields sensitive skin from diarrhoea and micro-organisms and unlike sprays with a colour dye it washes off easily with warm soapy water for inspecting the wound. It contains a proprietary carrier that helps the protective formula to adhere to the skin, so it stays where needed. Allows the wound to oxygenate, essential for good wound healing.
