For adults: Polyquaternium-73 is generally low risk when used in regular skin or hair products. It’s mainly a conditioner and most safety reviews say it’s okay to use in cosmetics with some limits.
Use products containing this ingredient as directed. Do a small patch test on your inner forearm if you have sensitive skin or are trying the product for the first time. Keep products away from your eyes and mouth. If the product is sprayed, use it in a well-ventilated area to avoid breathing in mist.
There is a low-level note that it can cause skin, eye, or breathing irritation in some situations (source: Cosmetic Ingredient Review). If you get redness, itching, swelling, stinging, or any trouble breathing, stop using the product right away and rinse the area with water. Avoid using on broken or inflamed skin. If irritation is severe or does not go away, seek medical advice.
