Description
A substance that repels or averts another. Hydrophobic materials, such as oils, fats, rubber, wax, silicone, and Teflon®, are water-repellent. Some chemicals, because of their smell or taste, repel animals and insects. For example, mosquitos and ticks are repelled by citronella, dimethyl phthalate, DEET and 2-ethyl hexanediol-1,3. Rodents are repelled by actidione, thiuram disulfide and hexachlorophene.
