Hydroxypropyltrimonium Maltodextrin Crosspolymer
What is Hydroxypropyltrimonium Maltodextrin Crosspolymer?
Hydroxypropyltrimonium Maltodextrin Crosspolymer is a synthetic, high-molecular-weight polymer created by crosslinking maltodextrin—a carbohydrate derived from corn or potato starch—with hydroxypropyltrimonium groups, imparting a positive charge. This modification makes it water-soluble and cationic, ideal for use in rinse-off personal care products like shampoos, conditioners, body washes, and facial cleansers. In formulations, it functions by forming a three-dimensional network that traps and evenly disperses insoluble particles such as exfoliating beads, pigments, or active ingredients, preventing settling or clumping. Its surfactant properties help reduce surface tension, supporting stable emulsions and mild foaming without stripping natural oils. The polymer's film-forming ability provides a smooth, non-sticky texture, enhancing product spreadability and user experience during application.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Benefits

Who It's For
A quick guide for who this ingredient may suit (and who should be cautious).
| Who May Benefit | Who Should Avoid |
|---|---|
| Users of exfoliating cleansers needing uniform particle suspension. | Those with known allergies to starch-derived ingredients. |
| Individuals seeking smooth-textured rinse-off hair and body products. | Users sensitive to quaternary ammonium compounds. |
| People preferring stable formulations that avoid separation over time. | Individuals preferring completely anhydrous product formulations. |
Safety Notes
- Rated low hazard by safety assessments with no significant irritation concerns.
- Non-comedogenic, unlikely to clog pores in rinse-off applications.
