Hydroxypropyl Guar CAS#39421-75-5
Excellent Water Solubility – Highly soluble in water, making it easy to disperse and incorporate into various formulations.
Stable Aqueous Performance – Its water solution remains stable at room temperature and across a broad pH range of 2.0 to 12.0.
Versatile Powder Form – Provided as a white or light-yellow powder, allowing convenient handling, storage, and mixing.
Controlled Thermal Behavior – Maintains viscosity under moderate temperatures, offering predictable performance before 70°C.
Hydroxypropyl guar gum typically appears as a white or pale yellow powder. It dissolves readily in water but is insoluble in organic solvents such as alcohol, ether, and ketones. Its aqueous solution remains relatively stable at room temperature and within a pH range of 2.0 to 12.0. However, when heated above 70 °C, its viscosity decreases rapidly, and it may undergo degradation when exposed to strong oxidizing agents.
