화학적 성질

white powder

화학적 성질

Microcrystalline cellulose and carboxymethylcellulose sodium occurs as a white or off-white odorless and tasteless hygroscopic powder containing 5–22% sodium carboxymethylcellulose. It is a water-dispersible organic hydrocolloid.

화학적 성질

Microcrystalline cellulose is a purified, partially depolymerized cellulose that occurs as a white, odorless, tasteless, crystalline powder composed of porous particles. It is commercially available in different particle sizes and moisture grades that have different properties and applications.

용도

High purity cellulose powders for partition chromatography.

용도

ACCEL-101 is most widely used for direct compression tableting and wet granulation. ACCEL-102 has similar compression properties to ACCEL-101. However, it has larger particle size and therefore, may be of value in improving the flow if fine powders. ACCEL

용도

cellulose is a thickener and an emulsifier. It is obtained from plants. cellulose (microcrystalline) is used as an emulsifier in cosmetic creams. It is the chief constituent of plant fiber.

용도

microcrystalline cellulose provides good slip and softness, and acts as a binder. A cellulose fiber isolated from colloidal crystals.

용도

Cellulose is a carbohydrate polymer made up of glucose units. It consists of fibrous particles and is used as a fiber source and bulking agent in low-calorie formulations.

용도

Microcrystalline Cellulose is a gum that is the nonfibrous form of cellulose, an alpha-cellulose. It is dispersible in water but not soluble, requiring considerable energy to disperse and hydrate. In this form it is used in dry applications such as tableting, capsules, and shredded cheese where it functions as a non-nutritive filler, binder, flow aid, and anticaking agent. By the addition of carboxymethylcellulose to the alpha-cellulose prior to drying, improved functional properties of hydration and dispersion are obtained. This product is designed for use in water dispersions, being insoluble in water but dispersing in water to form colloidal sols below 1% and white opaque gels above the 1% usage level. It is used as a heat shock stabilizer and bodying agent in frozen desserts, as an opacifier in low-fat dressings, as a foam stabilizer in whipped toppings, and as an emulsifier in dressings. Also termed cellulose gel.

정의

A natural carbohydrate high polymer (polysaccha- ride) consisting of anhydroglucose units joined by an oxygen linkage to form long molecular chains that are essentially linear. It can be hydrolyzed to glucose. The degree of polymerization is from 1000 for wood pulp to 3500 for cotton fiber, giving a molecular weight from 160,000 to 560,000. Cellulose is a colorless solid, d approximately 1.50, insoluble in water and organic solvents. It will swell in sodium hydroxide solution and is soluble in Schweitzer’s reagent. It is the fundamental con- stituent of all vegetable tissues (wood, grass, cotton, etc.) and the most abundant organic material in the world. Cotton fibers are almost pure cellulose; wood contains approximately 50%. The physical structure of cellulose is unusual in that it is not a single crystal but consists of crystalline areas embedded in amorphous areas. Chemical reagents penetrate the latter more easily than the former. Cel- lulose is virtually odorless and tasteless and is com- bustible, with an ignition point of approximately 450F. In some forms, it is flammable. For example, railroad shipping regulations require a flammable label on such items as burnt fiber, burnt cotton, wet waste paper, and wet textiles. Fires have been known to occur in warehouses in which telephone books were stored. These were undoubtedly due to heat buildup in the paper caused by microbial activity and self-sustaining oxidation.

생산 방법

Microcrystalline cellulose and carboxymethylcellulose sodium is a spray- or bulk-dried blend of microcrystalline cellulose and sodium carboxymethylcellulose. It is prepared by the chemical depolymerization of highly purified wood pulp. The original crystalline areas of the pulp fibers are combined with sodium carboxymethylcellulose, which serves as a protective colloid and also facilitates dispersion of the product; it is then either spray- or bulk-dried.

생산 방법

Microcrystalline cellulose is manufactured by controlled hydrolysis with dilute mineral acid solutions of α-cellulose, obtained as a pulp from fibrous plant materials. Following hydrolysis, the hydrocellulose is purified by filtration and the aqueous slurry is spraydried to form dry, porous particles of a broad size distribution.

일반 설명

Odorless, white powdery fibers. Density 1.5 g cm-3. The biopolymer composing the cell wall of vegetable tissues. Prepared by treating cotton with an organic solvent to de-wax Cellulose microcrystalline and removing pectic acids by extration with a solution of sodium hydroxide. The principal fiber composing the cell wall of vegetable tissues (wood, cotton, flax, grass, etc.). Technical uses depend on the strength and flexibility of its fibers. Insoluble in water. Soluble with chemical degradation in sulfuric aicd, and in concentrated solutions of zinc chloride. Soluble in aqueous solutions of cupric ammonium hydroxide (Cu(NH3)4(OH)2).

반응 프로필

Cellulose microcrystalline is combustible. Incompatible with strong oxidizing agents including bromine pentafluoride, sodium nitrate, fluorine, perchlorates, perchloric acid, sodium chlorate, magnesium perchlorate, F2, zinc permanganate, sodium nitrite, sodium nitrate, sodium peroxide. Nitration with a mixture of nitric and sulfuric acids produces Cellulose microcrystalline nitrates (celluloid pyroxylin, soluble pyroxyline, guncotton) which are flammable or explosive.

Pharmaceutical Applications

Microcrystalline cellulose and carboxymethylcellulose sodium is used to produce thixotropic gels suitable as suspending vehicles in pharmaceutical and cosmetic formulations. The sodium carboxymethylcellulose aids dispersion and serves as a protective colloid.
Concentrations of less than 1% solids produce fluid dispersions, while concentrations of more than 1.2% solids produce thixotropic gels. When properly dispersed, it imparts emulsion stability, opacity and suspension in a variety of products, and is used in nasal sprays, topical sprays and lotions, oral suspensions, emulsions, creams and gels.

Pharmaceutical Applications

Microcrystalline cellulose is widely used in pharmaceuticals, primarily as a binder/diluent in oral tablet and capsule formulations where it is used in both wet-granulation and direct-compression processes. In addition to its use as a binder/diluent, microcrystalline cellulose also has some lubricant and disintegrant properties that make it useful in tableting.
Microcrystalline cellulose is also used in cosmetics and food products.

공업 용도

Cellulose is the main constituent of the structureof plants (natural polymer) that, whenextracted, is employed for making paper,plastics, and in many combinations. Celluloseis made up of long-chain molecules inwhich the complex unit C6H10O5 is repeatedas many as 2000 times. It consists of glucose molecules with three hydroxyl groups foreach glucose unit.
One of the simplest forms of cellulose usedindustrially is regenerated cellulose, in whichthe chemical composition of the finished productis similar to that of the original cellulose. Itis made from wood or cotton pulp digested ina caustic solution. Cellophane is a regeneratedcellulose in thin sheets for wrapping and otherspecial uses include windings on wire andcable.

Safety Profile

A nuisance dust. When heated to decomposition it emits acrid smoke and irritating fumes.

Safety

Microcrystalline cellulose is widely used in oral pharmaceutical formulations and food products and is generally regarded as a relatively nontoxic and nonirritant material.
Microcrystalline cellulose is not absorbed systemically following oral administration and thus has little toxic potential. Consumption of large quantities of cellulose may have a laxative effect, although this is unlikely to be a problem when cellulose is used as an excipient in pharmaceutical formulations.
Deliberate abuse of formulations containing cellulose, either by inhalation or by injection, has resulted in the formation of cellulose granulomas.

저장

Microcrystalline cellulose and carboxymethylcellulose sodium is hygroscopic and should not be exposed to moisture. It is stable over a pH range of 3.5–11. Store in a cool, dry place. Avoid exposure to excessive heat.

저장

Microcrystalline cellulose is a stable though hygroscopic material. The bulk material should be stored in a well-closed container in a cool, dry place.
