JRS Hydrocolloids – Thermal Reversible Cellulose Ether Gels

Thermal Reversible Cellulose Ether Gels

Hydroxypropylmethylcellulose (HPMC) is a modified cellulose ether and appears as whitish powder in dry state. The degree of substitution (DS) and the methyl/hydroxypropyl ratio as well as the degree of polymerization define the characteristics of various grades. Cellulose ethers are generally soluble in cold water and yield clear solutions in a wide range of viscosity from 5 to 60,000 mPa·s (2 % w/w at 20 °C). HPMC is frequently used as rheology modifier, protective colloid in PVC production, water retention aid, pharmaceutical coating agent and more.


JRS HPMC Core Benefits

HPMC is typically used in dosages of 1-3 % (w/w) in aqueous systems. The clear solutions show thermal reversible gelation behavior (Pic. 1), where gelation temperature and resulting gel strength can be adjusted through available grades. Hydrophobic effects of the methoxyl groups facilitate thermo-reversible gelation. At lower temperatures, water molecules form enclosed structures around the hydrophobic groups, which disintegrate upon heating.The subsequently exposed methoxyl groups form hydrophobic aggregates, which are the reason for the gelation process (Graph. 1). HPMC is not very sensitive
towards pH and stable between 3 and 11.

The good compatibility with synthetic or natural polymers like PVOH, starch, xanthan or guar and many more is proven. Whereas very high salt concentrations can cause flocculation of the product.

JRS HPMC products are also suitable as film forming agents. Their transparent and flexible films exhibit certain tackifying effects. This stickiness can be exploited to adapt coating properties in green and finished state. Additionally, HPMC films form an
effective oil barrier with the KIT level 12.
