Polyquaternium-7

Polyquaternium-7 is a water-soluble cationic conditioning polymer commonly used in personal care and cosmetic formulations. It is a copolymer of acrylamide and diallyldimethylammonium chloride, valued for its conditioning, antistatic, and film-forming properties. In hair care products, it helps improve softness, smoothness, wet combability, and manageability while reducing static electricity and tangling.

In shampoos and body washes, Polyquaternium-7 can improve the sensory feel of the finished product and help maintain a pleasant conditioning effect after rinsing. It is compatible with many anionic surfactants, including Sodium Laureth Sulfate (SLES), making it particularly useful in cleansing formulations. It is also used in liquid hand washes and other rinse-off products to improve skin feel.

Commercial Polyquaternium-7 is commonly supplied as an aqueous solution, with polymer concentration varying by supplier and grade. Its typical usage level depends on the active polymer content and the desired conditioning performance. Formulators should follow supplier recommendations and evaluate viscosity, compatibility, stability, and finished-product performance before commercial production.
