Polyquaternium-4, also known as Polyquaternium-4, is a substance that has become a common ingredient in many body care products. It is a synthetic polymer that is primarily used in the cosmetic industry for its conditioning and anti-static properties. This polymeric conditioner is common in shampoos, conditioners and styling products where it forms a protective film on the surface of the hair to improve combability. It is also used in some types of deodorants, shaving creams, shaving gels or body creams.
Polyquaternium-4 is favored in the cosmetic industry for its ease of use and improved feel after applying the product to the hair. In addition, this polymer does not cause any side effects such as skin irritation, making it ideal for a wide variety of cosmetic products. Polyquaternium-4 also improves the durability of hair styles in high humidity, which is significant for people living in humid or tropical climates. This makes the hair better able to withstand external influences such as humidity or windy weather. This ingredient is also used to make hair gels, hairsprays and certain types of hair mousse, where it provides long-lasting hold and improved appearance without leaving a stiff or sticky residue.
