Polyquaternium-7 is non-toxic and safe for topical application when used in limits. Above 5%, it is considered to cause an allergic reaction on the body. According to a study, if the concentration of Polyquaternium-7 is below 5% in the formulation, then the amount of acrylamide is non-toxic in nature. Even if any allergic reaction occurs, it is very mild and subsides within 24 hours. Some people with hypersensitive skin or any other skin conditions have reported allergic contact dermatitis due to the presence of Polyquaternium-7 in skincare products.
