Polyquaternium-32 is a synthetic cationic polymer used in cosmetic and personal-care formulations, particularly in hair-care products. It is primarily recognized for its antistatic and film-forming properties. The polymer contains a quaternary ammonium functionality, giving it a positive charge that supports interaction with negatively charged surfaces such as hair.
Polyquaternium-32 is identified in cosmetic ingredient references as a polymeric quaternary ammonium salt. Its cosmetic functions include reducing electrostatic charging and forming a continuous film on hair, skin or nails.
The ingredient can be considered for formulations where improved hair manageability, surface conditioning, film formation and static control are desired.
Polyquaternium-32 is a cationic polymeric cosmetic ingredient with the INCI name Polyquaternium-32.
Its main cosmetic functions are:

Polyquaternium-32 belongs to the polyquaternium family of polymers containing quaternary ammonium functionality.
Its positive charge can support interaction with negatively charged hair surfaces. This characteristic is important for:
Polyquaternium-32 is recognized as a film-forming cosmetic ingredient. It can form a continuous polymeric film on hair, skin and/or nails.
Film formation can contribute to:
Polyquaternium-32 is recognized as an antistatic agent.
Its cationic character can help reduce electrostatic charging, particularly on hair.
Potential benefits include:
Polyquaternium-32 can be considered for a variety of hair-care formulations where film formation and antistatic performance are desired.
Potential applications include:
Commercial formulations containing Polyquaternium-32 are used in hair-care systems, including conditioning products and styling formulations.
Polyquaternium-32 can be incorporated into selected shampoo formulations.
Potential formulation benefits include:
Compatibility with surfactants and other formulation components should be evaluated during development.
Polyquaternium-32 can be considered for rinse-off and leave-on conditioning products.
Potential applications include:
Its cationic polymer character can support deposition and surface conditioning.
Polyquaternium-32 can support styling formulations through its film-forming characteristics.
Potential applications include:
The appropriate grade and concentration should be selected according to the required film characteristics and sensory profile.
Polyquaternium-32 is also identified in cosmetic references as occurring in nail-care products.
Its film-forming functionality may be useful in selected nail-care formulations.
When formulating with Polyquaternium-32, formulators should evaluate:
Because Polyquaternium-32 is a cationic polymer, its interaction with anionic surfactants and other charged ingredients can influence formulation performance.
Polyquaternium-32 is listed in the EU cosmetic ingredient framework with restriction reference III/66. The restriction is associated with the broader regulatory entry covering polyacrylamides, so the exact regulatory requirements should be checked against the current applicable regulation and the finished-product formulation.
For raw-material quality control, residual monomer specifications should therefore be addressed in the applicable technical documentation and COA.
Polyquaternium-32 can be considered for:
