Polyquaternium 27

Polyquaternium-27 (CAS 132977-85-6), commercially available as Mirapol 175 and Mirapol 95, is a quaternary ammonium copolymer used across personal care and industrial applications.

It functions primarily as a conditioning agent and film-former, delivering substantivity to hair and skin surfaces while contributing to rheology control in aqueous formulations.

In hair care, it deposits a conditioning film on damaged or chemically treated hair, improving combability, reducing static, and enhancing wet and dry feel in shampoos and conditioners.

Skin care formulators incorporate it into lotions and body washes where its humectant character supports moisture retention and a smooth after-feel for the end user.

In textile processing, it modifies fiber surfaces to improve softness and antistatic performance in finishing baths. Paper and leather manufacturers use it as a surface-treatment additive.

This chemical influences wetting behavior and surface uniformity across various substrates. Polyquaternium-27 is typically supplied as an aqueous solution, with active content varying by grade.

Mirapol 95 and Mirapol 175 represent distinct commercial grades with differing molecular weight profiles suited to different application requirements and formulation viscosities.

It is available in technical and cosmetic grades, with cosmetic-grade material meeting the purity standards expected for leave-on and rinse-off personal care formulations.
