Polyquaternium is a neologism used to emphasize the presence of quaternary ammonium centers in the polymer. Being positively charged, polyquaterniums are capable to neutralize the negative charges of most shampoos and hair proteins and help hair lie flat.

International Nomenclature for Cosmetic Ingredients (INCI) has approved at least 40 different polymers under the polyquaternium designation. Alfa Chemistry offers various of polyquaterniums, including polyquaternium-51 (cas 125275-25-4), polyquaternium-28 (cas 131954-48-8), polyquaternium-47 (cas 197969-51-0), polyquaternium-39 (cas 25136-75-8), polyquaternium-6 (cas 26062-79-3), polyquaternium-37 (cas 26161-33-1), polyquaternium-7 (cas 26590-05-6), polyquaternium-11 (cas 53633-54-8), polyquaternium-22 (cas 53694-17-0), polyquaternium-1 (cas 68518-54-7), polyquaternium-10 (cas 68610-92-4), polyquaternium-4 (cas 92183-41-0), and polyquaternium-16 (cas 95144-24-4).


It should be noted not all the polyquaterniums approved by INCI can be used in the hair care industry, but the following are suitable.



Having excellent combability, holding, gloss and antistat properties, polyquaternium-4, the cellulosic polymer substantive to skin and hair, exhibits outstanding properties in hair care products.
