Hydroxypropyl methylcellulose (HPMC) is a type of cellulose-based polymer that is used in a variety of products, including pharmaceuticals, food, and cosmetics. It is a non-toxic, non-irritating, and non-allergenic substance that is used as a thickening agent, emulsifier, stabilizer, and suspending agent.
HPMC is a semi-synthetic derivative of cellulose, which is a naturally occurring polysaccharide found in plants. It is made by reacting cellulose with propylene oxide and then reacting the resulting product with hydroxypropyl chloride. This process results in a polymer with a wide range of properties, such as being able to form gels and films, and having a high degree of water-solubility.
HPMC is used in a variety of products, including pharmaceuticals, food, and cosmetics. In pharmaceuticals, it is used as a binder, disintegrant, and suspending agent. It is also used to improve the flow properties of powders, as well as to improve the stability of the active ingredients in the formulation. In food, it is used as a thickening agent, emulsifier, stabilizer, and suspending agent. In cosmetics, it is used as a thickener and emulsifier.
HPMC is generally considered to be safe for human consumption. It is not absorbed by the body and is eliminated in the feces. It is also not known to cause any adverse reactions in humans.
In addition to its use in pharmaceuticals, food, and cosmetics, HPMC is also used in industrial applications. It is used as a binder in the manufacture of paper, as a thickener in paints and coatings, and as a stabilizer in emulsions.
