Hypromellose 2208 and 2910

Hypromellose, also known as hydroxypropy methycellulose (HPMC), is a non-toxic and non-ionic cellulose ether that is used in a variety of applications, including pharmaceuticals, cosmetics, and food products. HPMC is available in a range of grades,incuding Hypromellose208 and 2910,which have diferent properties and applications.

Hypromellose 2208 is a low viscosily grade of HPMC that is commonly used as a binder,thickener,and film former in pharmaceuticals.its often used in tablet coatings,where it provides a smooth,glossy surface and improves the tablet's stability. Hypromellose 2208 is also used in ophthalmic formulations.where it acts as a lubricant and improves the viscosity of the formulation.

Hypromellose 2910 is a higher viscosity grade of HPMC that is used as a thickener, binder,and emulsifier in a range of applications.In pharmaceuticals, it is often used as a sustained-release agent, as it slowly releases the active ingredient over time.Hypromellose 2910 is also used in cosmetics,where it provides a thickening effect improves the stability of emulsions, and enhances the texture of the product.

In summary, Hypromellose 2208 and 2910 are two grades of HPMC with different properties and applications.Hypromellose 2208 is a low viscosity grade used in pharmaceuticals, while Hypromellose 2910 is a higher viscosity grade used in pharmaceuticals, cosmetics, and other applications.
