What Is Hydroxy Propyl Methyl Cellulose
Hydroxy Propyl Methyl Cellulose (HPMC), also named Hypromellose, is a non-ionic cellulose mixed ether compound. It also is a semi-synthetic, inactive, viscoelastic polymer. The aqueous solution has surface activity, high transparency and stable performance. It is often used as a lubricant in ophthalmology, or as an excipient or excipient in oral medicines, commonly found in a variety of different types of commodities. As a food additive, hydroxypropyl methylcellulose can be used as an emulsifier, thickener, suspension agent and a substitute for animal gelatin.
Chemical Property of Hydroxy Propyl Methyl Cellulose
Hydroxy Propyl Methyl Cellulose is a white powder or white loose fiber solid with a particle size of 80 mesh sieve. It has similar cold-water and hot-water insoluble properties to methyl cellulose, and its solubility in organic solvents exceeds water solubility, soluble in anhydrous methanol and ethanol, and soluble in chlorinated hydrocarbons such as dichloromethane, trichloroethane, and organic solvents such as acetone, isopropyl alcohol and diacetone alcohol. When dissolved in water, they combine with water molecules to form colloids. It is stable to acids and bases, and is not affected in the pH range of 2 ~ 12. Although non-toxic, hydroxypropyl methylcellulose is flammable and reacts violently with oxidants.
The viscosity of HPMC products increases with the increase of concentration and molecular weight, and the viscosity begins to decline when the temperature rises, and at a certain temperature, the viscosity suddenly rises and gelation occurs. The gel temperature of low-viscosity products is higher than that of high-viscosity products. Its aqueous solution is stable at room temperature, except for enzymatic degradation, the general viscosity does not degrade. It has special thermal gelation properties, good film forming properties and surface activity.
Application field of Hydroxy Propyl Methyl Cellulose
Hydroxy Propyl Methyl Cellulose is rich in functions and widely used, mainly used in construction industry, chemical industry, cosmetics industry, food industry, pharmaceutical industry, kiln industry and other industries. Here we will browes some of its important uses as below:
Construction Industry
1, Cement Mortar: improve the dispersion of cement-sand, greatly improve the plasticity and water retention of mortar, to prevent cracks have an effect, can enhance the strength of cement.
2, Ceramic Tile Cement: improve the plasticity of pressed ceramic tile mortar, water retention, improve the glue of ceramic tile, prevent pulverization.
3, The Coating of Asbestos and other Refractory Materials: as a suspension agent, fluidity improvement agent, but also improve the rubber relay to the base.
4, Gypsum Slurry: improve water retention and processability, improve the adhesive force on the base.
5. Joint Cement: Added to the joint cement used in gypsum board to improve fluidity and water retention.
6, Latex Putty: improve the fluidity and water retention of resin latex-based putty.
7, Plaster: as a substitute for natural paste, can improve water retention, improve the glue relay with the base.
8, Paint: as a plasticizer of latex paint, it has a role in improving the operational performance and fluidity of paint and putty powder.
9, Spraying Coating: to prevent cement or latex spraying only material filler sinking and improve fluidity and spray pattern has a good effect.
10, Cement, Gypsum Secondary Products: as cement – asbestos and other hydraulic material extrusion molding binder used to improve fluidity, can get uniform molding products.
11, Fiber Wall: due to the anti-enzyme and anti-bacterial effect, as a binder for the sand wall is effective.
12, Other: can be used for thin mortar mortar and mortar operator (PC version) of the bubble retention agent.
Chemical Industry
1. Polymerization of Vinyl Chloride and Vinylidene: as a suspension stabilizer and dispersant during polymerization, it can be used with polyvinyl alcohol (PVA) hydroxypropyl cellulose (HPC) to control particle shape and particle distribution.
2, Adhesive: As a adhesive for wallpaper, instead of starch can usually be used with vinyl acetate latex paint.
3, Pesticides: added to pesticides, herbicides, can improve the adhesion effect of spraying.
4, Latex: improve asphalt emulsion stabilizer, styrene butadiene rubber (SBR) latex thickening agent.
5, Binder: as a pencil, crayon forming adhesive.
Cosmetics Industry
1, Shampoo: improve the viscosity of shampoo, washing agent, cleaning agent and bubble stability.
2, Toothpaste: improve the fluidity of toothpaste.
Food Industry
1, Canned Citrus: to prevent in storage due to the decomposition of citrus and white deterioration to achieve freshness.
2, Cold Fruit Products: Add to sherbet and ice to make the taste better.
3, Sauce: as a sauce, tomato sauce emulsifying stabilizer or thickening agent.
4, Cold Water Coating Glazing: used for frozen fish storage, can prevent discoloration, quality reduction, with methyl cellulose or hydroxypropyl methyl cellulose aqueous solution coated glazing, and then frozen ice.
Pharmaceutical Industry
1, Coating: the coating agent into an organic solvent solution or aqueous solution to the tablet, especially to the particles made of spray coating.
2, Slow-release Agent: 2-3 grams per day, each time 1-2G dosage, in 4-5 days to show the effect.
3, Ophthalmic Medicine: Since the osmotic pressure of methyl cellulose aqueous solution is the same as that of tears, it is less irritating to the eyes, so it is added to the ophthalmic medicine as a lubricant to contact the lens of the eye.
4, Gel Agent: as a base material for gel-like external medicine or ointment.
5, Impregnating Drug: as a thickening agent, water retention agent.
Kiln Industry
1, Electronic Material: as a ceramic electric denser, the alumina ferrite magnet extrusion molding adhesive, can be used with 1.2-propylene glycol.
2, Glaze: used as ceramic glaze and with enamel paint, can improve bonding and processability.
3, Refractory Mortar: added to refractory brick mortar or cast furnace, can improve plasticity and water retention.
Other Industries
1, Fiber: as a printing dye paste for pigments, boron soil forest dyes, basic dyes, textile dyes, in addition, in kapok ripple processing, can be used with heat hardening resin.
2, Paper: used for carbon paper rubber and oil processing and other aspects.
3, Leather: as the final lubrication or disposable adhesive use.
4, Water-based ink: added to water-based ink, ink, as a thickening agent, film forming agent.
5, Tobacco: as an adhesive for recycled tobacco.
Hydroxy Propyl Methyl Cellulose Side Effects
This product is safe and non-toxic, can be used as a food additive, no heat, no irritation to skin, mucous membrane contact, generally considered to be safe.
