【Introduction】
Name: Hydroxypropyl Methyl Cellulose(HPMC)
Appearance and properties: white or almost white fibrous or granular powder
CAS NO:9004-65-3
Abbreviation: HPMC
Molecular Formula: [C6H7O2(OH)x-m-n (OCH3 )m (OCH2CH (OH)CH3 )n]x
【Characteristics】
HPMC is odorless, tasteless,non-toxic cellulose ethers producted from natural hIgh molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protetive colloid properties of surface activity and maintain moisture function properties ect.
Properties
1 . Resistance to salting out :HPMC is a nonionic cellulose ether and it is not a polyelectrolyte . The aqueous solution of HPMC is comparatively stable even in the presence of metal salts or organic electrolytes . However , when the concentration of electrolytes exceeds a certain limit , gelation and precipitation may result .
2. PH stability :The viscosity of an aqueous solution of HPMC is hardly affected by acid or alkali , and the product can develop an original viscosity in the range of 3 . 0~11 . 0 . Therefore , the solution viscosity tends to keep stable during prolonged storage .
3. Surface activity :An aqueous solution of HPMC has a high surface activity and functions as a protective colloid agent , emulsion stabilizer and dispersant .
4 . Film forming :HPMC provides a strong , flexible and transparent film having a good barrier property against oil and grease . In food application , this property is often utilized for water retention and oil adsorption .
【Technical requirements】
1.Appearance: white to yellowish powder or grains.
2.Viscosity Specification as below
3.Techinical Specifications:
Note: Any other special requirement for the product can be satisfied through the negotiation.
【Application】
HPMC are widely used as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids for food and pharma,
The high viscosity specification is widely used in the sustained and controlled release system of hydrophilic gel matrix. The low-viscosity grade is used as the main shell material in tablet coating and non-gelatin capsule formulations, and is also a commonly used binder in wet granulation.
