What is polyquaternium?

Answer 1

Polyquaternium polymers are synthetic polymers that contain quaternary ammonium groups as part of the functional part of the polymers. Ammonium groups contain a positive charge and are balanced non-covalently with anions like chloride or sulfate, or internally with covalently bound anionic groups like carboxylate, sulfate, or sulfonate. These polymers are typically found in hair care products and cosmetics. Most of them are non-toxic and have no LD50's calculated since they have not been found to have any toxicity.

Answer 2

Polyquaternium is a type of polymer that is commonly used in personal care products such as shampoos and conditioners. It is known for its conditioning and antistatic properties, helping to improve the texture and manageability of the hair. Polyquaternium ingredients are typically derived from a quaternary ammonium compound, which gives them a positive charge that helps them adhere to the hair and provide conditioning benefits.
