Did you mean Cationic Polymers?

GlossaryCationic Polymers

large molecules with positive charges that condition hair

Cationic polymers are large molecules that carry a positive charge. They are often used in hair care products because they can easily bind to the negatively charged surfaces of hair strands, helping to condition and smooth the hair. This positive charge also makes them effective in various industrial applications, such as water treatment, where they help to remove negatively charged contaminants.
