Cassia Hydroxypropyltrimonium Chloride is a cationically modified cassia gum polymer used mainly as a hair-conditioning and antistatic ingredient in cosmetic and personal-care formulations. It is derived from cassia seed endosperm and modified by introducing hydroxypropyltrimonium groups onto the polysaccharide structure. The resulting polymer carries cationic functionality that supports interaction with the hair surface.
Cassia gum is a galactomannan polysaccharide obtained from the endosperm of Cassia tora or Cassia obtusifolia seeds. Cosmetic ingredient references describe Cassia Hydroxypropyltrimonium Chloride as a derivative of this polysaccharide with trimethylammonium functionality.
The ingredient is particularly useful in hair-care formulations where conditioning, detangling, softness, smoothness, manageability, antistatic performance and improved hair feel are desired. It can be used in both rinse-off and selected leave-on formulations.
The cationic nature of Cassia Hydroxypropyltrimonium Chloride allows the polymer to interact with the hair surface and contribute to improved conditioning. It can help leave hair feeling softer, smoother and easier to manage.
Cassia Hydroxypropyltrimonium Chloride can support improved wet and dry combability in suitable hair-care systems. Its conditioning effect can help reduce friction during combing and improve overall manageability.
The ingredient is recognized for antistatic functionality. It can help reduce electrostatic charge on hair and contribute to improved hair manageability.
The cationic polymer can form an adsorbed conditioning layer on hair, contributing to smoothness, softness and improved sensory properties. Commercial applications include shampoos, conditioners, masks, leave-in treatments and styling products.
Cassia Hydroxypropyltrimonium Chloride can provide conditioning without necessarily producing the heavy feel associated with some higher-build-up conditioning materials. Certain commercial grades are promoted for conditioning, volume and low-build-up applications.
Cassia Hydroxypropyltrimonium Chloride can be incorporated into shampoo systems as a cationic conditioning polymer. Research on cationically modified cassia galactomannans has evaluated their use in two-in-one conditioning shampoos and their interaction with common surfactant systems.
It can be used in rinse-off conditioners and treatment products where smoothness, softness, combability and manageability are important formulation targets.
Suitable grades can be incorporated into leave-in conditioners, hair creams, detangling products and styling systems where conditioning and antistatic properties are desired.
Cassia Hydroxypropyltrimonium Chloride is a polymeric ingredient, so its performance varies with molecular characteristics, cationic charge density, degree of substitution, concentration and processing conditions.
Commercial grades can have different viscosity and moisture specifications. One commercial technical data sheet reports a viscosity of 40–200 cP for a 1% aqueous solution at 25°C, maximum moisture of 6% and maximum sulfated ash of 6% for a specific Cassia Hydroxypropyltrimonium Chloride grade. These values should not automatically be treated as universal specifications for every grade.
For formulation development, the polymer should be dispersed according to the selected grade's processing instructions. Compatibility with surfactants, electrolytes and other conditioning polymers should be evaluated in the finished formulation.

It is primarily used as a hair-conditioning and antistatic ingredient in shampoos, conditioners and other hair-care formulations.
Yes. It is a cationically modified polysaccharide containing quaternary ammonium functionality.
Yes. It is derived from cassia gum obtained from the endosperm of Cassia tora or Cassia obtusifolia seeds.
Yes. Cationically modified cassia polymers have been evaluated in conditioning shampoo formulations.
It can support improved combability and manageability through its conditioning action.
Yes. Antistatic is one of its recognized cosmetic functions.
A single fixed molecular formula should not be assigned because it is a modified polysaccharide polymer whose composition depends on the degree of substitution.
Important specifications include appearance, moisture, viscosity, pH, particle characteristics, sulfated ash and degree or level of cationic substitution. Exact limits depend on the commercial grade.
