Hydroxypropyl methyl cellulose is a propylene glycol ether of methyl cellulose, in which hydroxypropyl and methyl groups are combined with ether bonds and anhydrous glucose rings of cellulose, and are white to off-white cellulose powder or particles, which have the characteristics of cold water dissolution and hot water insolubility similar to methyl cellulose. Solubility in organic solvents is better than water solubility, soluble in anhydrous methanol and ethanol solutions, but also soluble in chlorinated hydrocarbons and ketones and other organic solvents. Soluble in water, the water-soluble liquid has surface activity, forms a film after drying, and undergoes reversible conversion from sol to gel after heating and cooling. It can be used alone in cold drinks, or combined with other emulsifiers and stabilizers, with a maximum dosage of 1% in cold drinks. In recent years, it has been widely used in petrochemical, paper making, leather, textile printing and dyeing, medicine, food, cosmetics and other industries, as a dispersant, thickener, adhesive, excipient, capsule, oil-resistant coatings and fillers.
Special use of product:
0.45~1.0% w/w hydroxypropyl methylcellulose can be used as a thickening agent for eye drops and artificial tears.
When the concentration is 0.1%, it can be used in liquid nasal preparations, and hydroxypropyl methylcellulose can be used as emulsifier, suspension agent and stabilizer for local gels and ovens.
It can form a protective gel to prevent droplets and particles from coalescing or coagulating, thus inhibiting the formation of sediments.
As one of the most commonly used film coating materials in the consistency evaluation variety.
Hydroxypropyl methylcellulose is widely used in oral, ophthalmic, nasal and local drugs.
It is mainly used as adhesive for tablets, film coating materials, and skeleton materials for sustained-release tablets.
Reasonable interweaving substitution of methoxy and hydroxypropoxy, with double properties of lipophilic and hydrophilic
1.Thermal gel properties: With the increase of methoxy content, the gel point decreases, the water solubility increases, and the surface activity increases
2.Wide range of pharmaceutical applications: with gel, viscosity, thickening, bonding, film formation, suspension, emulsification and other characteristics. Different levels of products with different viscosity and substitution degree can be selected
3.When used in the preparation of plant capsules, it can be compatible with most of the excipiants and there is no cross-linking reaction, Maillard reaction and condensation reaction after filling
4.The plant capsules produced by Prospect E series HPMC have the advantages of pure natural, safe and pollution-free, low water content, good toughness, no brittle-crushing, stable disintegration performance and so on.
