Description
In the HPMC E15 “E15” indicates to a specific viscosity ,15 mPa.s at 2% concentration. It is a visco-elastic polymer, semi-synthetic & inert. It is extensively used in the sectors like pharma, cosmetics and food industries because of having various properties like film-forming, thickening and binding properties.
It is water soluble and does not react to other substances. It is soluble in cold water and forms a clear and glutinous solution. In tablet production, it acts as an adhesive which helps to enhance the hardness and stability of the tablet.
Characteristics of HPMC E15:
- HPMC E15 is not naturally obtained, it is produced from cellulose. It is also known as chemically inert because of having property of not reacting with other substances.
- It has the property to become in both states which is known as Visco-Elastic Polymer because it can flow like a liquid, and it can also become in solid state.
- It is soluble in cold water and forms a clear and glutinous solution. It is to be noted that it is not soluble in hot water and other solvents.
- It is also known for its film forming properties, when it is diluted in water, it forms a crystal clear and flexible film which can be used for coating for tablets.
Applications:
Pharmaceuticals: It is used as a binder in tablet, coating agent, thickener, and sustained release agent in various tropical and oral drug formulations, it is also used in eyedrop as a low viscosity product.
Cosmetics: In cosmetics, it is used as a thickener, binder, and film forming in cosmetic products such as creams, lotions, and gels.
Food Industry: In Food Industry sector, it is used as a thickening agent, as a stabilizer and an emulsifier in various food products.
Key Importance of HPMC E15:
- It improves the stability and shelf life of the products.
- It provides controlled release of active ingredients like in tablets.
- It helps to meet specific product requirements.
- It can be used in a wide range of applications.
- It acts as film coating application by forming smooth, uniform and tough coating on the surface of tablets, pills, etc.
- It is used in ophthalmic eyedrop as a viscosity enhancer.
Storage:
Store HPMC E15 solutions in a cool and dry place, also ensure that to keep away from direct sunlight and heat.
