Polyquaternium-93 is a synthetic polyquaternium-type cosmetic ingredient associated with hair-care and personal-care formulations. Polyquaternium ingredients are a broad family of polymers containing quaternary ammonium functionality and are widely used in cosmetic formulations for conditioning, film formation, antistatic performance, hair manageability and other formulation benefits.
Polyquaternium-93 is identified in cosmetic ingredient catalogues as a cosmetic ingredient used for hair conditioning. It has also appeared in technical and patent literature among polyquaternium materials considered for cosmetic and personal-care applications.
Because polymeric cosmetic ingredients can have different commercial grades, the exact composition, molecular characteristics, active content and analytical specifications should always be confirmed from the manufacturer's technical documentation.
Polyquaternium-93 belongs to the broader polyquaternium family of cationic polymeric cosmetic ingredients.
The term Polyquaternium does not describe one single chemical structure. Different numerical designations represent different polymer compositions. Their quaternary ammonium functionality can provide interaction with negatively charged surfaces such as damaged or treated hair fibres.
Polyquaternium-93 can therefore be considered primarily for conditioning-focused hair-care formulation development.
The exact polymer architecture and molecular characteristics of a commercial Polyquaternium-93 material should be established from its supplier COA, TDS and SDS rather than inferred from the polyquaternium number alone.
Polyquaternium-93 can be considered in cosmetic formulations where conditioning and improved hair manageability are desired.
The performance of a cationic polymer depends on its molecular characteristics, charge density, concentration, formulation environment and interactions with other ingredients.
Hair conditioning is the principal cosmetic application associated with Polyquaternium-93.
A conditioning polymer can contribute to improvements in the sensory characteristics of hair, including:
The actual performance should be established through formulation-specific testing.
Polyquaternium-93 can be evaluated in conditioning shampoo systems where cleansing and conditioning are required in the same formulation.
In shampoo systems, a suitable conditioning polymer may contribute to improved post-wash hair feel and manageability.
Formulators should assess compatibility with the complete surfactant system, particularly where anionic surfactants are present.
Conditioners provide an appropriate formulation environment for evaluating hair-conditioning polymers.
Polyquaternium-93 may be considered in rinse-off conditioner formulations intended to provide:
The appropriate grade and concentration should be determined experimentally.
Polyquaternium-93 can also be evaluated in leave-in formulations when longer-lasting conditioning and improved manageability are desired.
Potential formulation categories include:
The final sensory profile depends on the selected grade and the rest of the formulation.
Conditioning polymers are often selected to improve the handling characteristics of hair.
Polyquaternium-93 can be evaluated in products intended for dry, difficult-to-comb, chemically treated or otherwise challenging hair types.
Performance should be assessed using appropriate wet-combing, dry-combing, sensory and formulation-stability evaluations.
Polyquaternium-93 is a polymeric material and its incorporation characteristics may vary between commercial grades.
The supplier's recommended addition procedure should be followed. Appropriate dispersion or dissolution is important for consistent distribution throughout the formulation.
The polymer should be incorporated using a controlled addition process to minimize localized concentration and incomplete hydration or dispersion.
Processing conditions should follow the technical recommendations applicable to the specific commercial grade.
The final formulation pH should be selected according to the complete cosmetic formulation.
A universal optimum pH should not be assigned to Polyquaternium-93 without grade-specific technical evidence.
Formulation stability and conditioning performance should be evaluated across the intended pH range.
For shampoo and cleansing formulations, compatibility with the selected surfactant system is important.
The interaction between cationic polymers and anionic surfactants can affect:
Laboratory compatibility testing is recommended before commercial-scale production.
Polyquaternium-93 should be evaluated alongside other polymers, conditioning agents, surfactants, emulsifiers and rheology modifiers.
The combined system may influence viscosity, clarity, deposition, sensory characteristics and overall stability.
A universal use concentration should not be stated without verified supplier-specific technical data.
The appropriate concentration should be established according to the commercial grade, active content and intended cosmetic application.
Polyquaternium-93 can be considered for:
Polyquaternium-93 can be considered for cosmetic formulation development where polymeric hair conditioning and improved manageability are required.

Polyquaternium-93 is a synthetic polyquaternium-type cosmetic ingredient associated primarily with hair-conditioning applications.
It is primarily associated with hair conditioning and can be evaluated in shampoos, conditioners, leave-in products and other hair-care formulations.
Polyquaternium-93 is described as a synthetic polyquaternium-type ingredient.
It can be evaluated in conditioning shampoo formulations, provided that the selected grade is compatible with the surfactant system and other formulation ingredients.
Yes. Its association with hair conditioning makes it relevant to rinse-off and leave-in conditioning formulations.
A reliable current CAS number could not be verified for the exact Polyquaternium-93 INCI identity. The commercial supplier's COA/TDS should therefore be used to establish the applicable CAS identification.
No. Polyquaternium-93 and Quaternium-93 are different INCI designations. Current COSMILE Europe has a separate entry for Quaternium-93, which is a synthetic hair-conditioning ingredient.
Polyquaternium materials are chemically distinct polymers, and assigning a CAS from another polyquaternium or Quaternium ingredient can result in an incorrect product identity. The supplier's technical documentation should therefore control the commercial CAS entry.
