Methyl celluloses have four important properties. They can form aqueous solutions with a wide<br />

range of viscosities (variable thickening, stabilising and bulking properties); they are surface-active<br />

(emulsifying properties); they can have a high yield point (suspending properties); and they form gels<br />

ar high temperatures that melt on cooling (stabilising agents for foods with heat-sensitive components<br />

like the toppings in pizzas). Properties (viscosity, melting points, etc.) vary considerably with the<br />

molecular weight and degree of methylation<br />
