Polyquaternium-24 is a cationic polymeric cosmetic ingredient used primarily in hair-care, skin-care and personal-care formulations. It is recognized for its antistatic and film-forming properties and can provide substantive conditioning, smoothing and improved surface feel.
Polyquaternium-24 is a quaternized cellulose-based polymer produced by modifying hydroxyethyl cellulose with a quaternary ammonium-containing epoxide. This structure combines the film-forming characteristics of a cellulose-based polymer with the substantive properties associated with cationic functionality.
The ingredient can form a thin film on hair or skin and can help improve surface characteristics. Its cationic nature provides substantivity toward hair, making it useful in formulations where conditioning, manageability and antistatic performance are required.
Polyquaternium-24 is a quaternary ammonium-modified cellulose polymer used as a functional cosmetic ingredient.
According to cosmetic ingredient references, its principal listed functions are:
It can also provide substantive conditioning and sensory benefits in suitable cosmetic formulations.
INCI Name: Polyquaternium-24
CAS Number: 98616-25-2
Chemical Class: Cationic Polymer
Polymer Type: Quaternized Hydroxyethyl Cellulose
Primary Cosmetic Functions: Antistatic, Film Forming
Chemical Description: Cellulose ether with alpha-(3-(dodecyldimethylammonio)-2-hydroxypropyl)-omega-hydroxypoly(oxy-1,2-ethanediyl) chloride.
Polyquaternium-24 contains quaternary ammonium functionality that gives it a cationic character. This allows the polymer to interact substantively with surfaces such as hair.
Its cationic nature can support:
Polyquaternium-24 is listed as a film-forming cosmetic ingredient. It can form a continuous polymeric film over the application surface.
This characteristic can support:
Film performance depends on polymer grade, concentration and the formulation system.
Polyquaternium-24 is also classified as an antistatic ingredient.
In hair-care formulations, its cationic character can help reduce static electricity and improve hair manageability.
Potential benefits include:
Polyquaternium-24 can provide substantive conditioning characteristics because its cationic polymer structure can interact with hair surfaces.
It may contribute to:
Polyquaternium-24 can be considered for selected shampoo systems where conditioning and improved post-wash feel are desired.
Potential formulation benefits include:
Compatibility with the surfactant system should be evaluated during formulation development.
Polyquaternium-24 can be incorporated into selected rinse-off and leave-on conditioning products.
Potential applications include:
The film-forming characteristics of Polyquaternium-24 make it suitable for selected hair-styling formulations.
Potential applications include:
The required polymer grade should be selected according to the desired film characteristics, sensory profile and formulation viscosity.
Polyquaternium-24 can also be used in selected skin-care and personal-care formulations because of its film-forming and substantive characteristics.
Potential applications include:
Commercial ingredient systems containing Polyquaternium-24 have also been developed for skin and hair applications where film formation, moisturization and substantivity are desired.
When formulating with Polyquaternium-24, formulators should evaluate:
Because Polyquaternium-24 is cationic, interactions with anionic surfactants and other charged ingredients can influence deposition, clarity and viscosity.
Polyquaternium-24 can be considered for:
