9000-11-7 Usage
Description
Carboxymethyl cellulose (CMC) is a water-soluble cellulose ether gum that is manufactured by reacting sodium monochloroacetate with alkali cellulose to form sodium carboxymethyl cellulose. It is a linear polymer of glucopyranose units connected by α-1,4-glucoside links and is derived from cellulose, which is the major structural carbohydrate of green plants. CMC is available in a variety of types that differ in viscosity and degree of substitution (the number of sodium groups per unit). It functions as a thickener, stabilizer, binder, film former, and suspending agent.
Uses
Used in Food Industry:
Carboxymethyl cellulose is used as a thickener, stabilizer, and emulsifier in a variety of foods, including dressings, ice cream, baked goods, puddings, and sauces. It helps to improve the texture, stability, and mouthfeel of these products, and its usage range is from 0.05 to 0.5%.
Used in Cosmetic Industry:
Carboxymethyl cellulose is used as a thickener in cosmetic formulations, such as bath preparations, beauty masks, hand creams, and shampoos. It is considered a non-comedogenic raw material, meaning it does not clog pores and is suitable for use in skincare products.
Used in Pharmaceutical Industry:
Carboxymethyl cellulose serves as a pharmaceutic aid, acting as a suspending agent, tablet excipient, and viscosity-increasing agent. It helps to improve the stability, consistency, and delivery of pharmaceutical formulations.
Used in Industrial Applications:
Carboxymethyl cellulose is used in various industrial applications, such as a dispersant, flocculant, and depressant in the flotation process. It is also used in the production of lignin sulfonate, an amorphous polyphenolic compound derived from enzymatic polymerization of three phenylpropanoid monomers.
Used in Construction and Other Industries:
CMC can significantly increase the viscosity of solutions when dissolved in water, making it useful as a thickener, dispersion, emulsification, suspension, and protective colloid in various industries, including food, pharmaceutical, cosmetic, oil, paper, textiles, and construction.
Brand Names:
Some brand names of carboxymethyl cellulose include Celluvisc (Allergan), Refresh Plus, and Cellufresh Formula (Allergan).
Product features
Carboxymethyl cellulose (CMC) is tackifier, at room temperature, it is non-toxic tasteless white flocculent powder, it is stable and soluble in water, aqueous solution is neutral or alkaline transparent viscous liquid, it is soluble in other water-soluble gums and resins, it is insoluble in organic solvents such as ethanol. Carboxymethyl cellulose is the substituted product of cellulosic carboxymethyl group. According to their molecular weight or degree of substitution, it can be completely dissolved or insoluble polymer, the latter can be used as the weak acid cation of exchanger to separate neutral or basic proteins.
Carboxymethyl cellulose can form highly viscous colloidal solution with adhesive, thickening, flowing, emulsifying, shaping, water, protective colloid, film forming, acid, salt, suspensions and other characteristics, and it is physiologically harmless, so it is widely used in the food, pharmaceutical, cosmetic, oil, paper, textiles, construction and other areas of production.
Application: It is used in cigarette adhesive, fabric sizing, footwear paste meal, home slimy. It is used in interior painting architectural, building lines melamine, thickening mortar, concrete enhancement. It is used in refractory fiber, ceramic production molding bond. It is used in oil drilling, exploration address slurry thickening, reducing water loss, quality paper surface sizing. It can be used as soap and washing powder detergent active additives, as well as other industrial production on the dispersion, emulsification, stability, suspension, film, paper, polishing and the like. Quality product can be used for toothpaste, medicine, food and other industrial sectors.
Instructions: Warm water and cold water can be ok when prepares the solution, it can be used with stirring until it completely melts. The amout of added water depends on variety and the use of multiple requirements.
High viscosity sodium carboxymethyl cellulose (HV-CMC) is a white or slightly yellow fibrous powder, hygroscopic, odorless, tasteless, non-toxic, easy to ferment, insoluble in acids, alcohols and organic solvents, easily dispersed to form colloidal solution in water. It is reacted by the acid and fibrous cotton, it is mainly used for water-based drilling fluids tackifier, it has certain role of fluid loss, it has strong salt and temperature resistance especially.

Preparation
Sodium carboxymethyl cellulose is produced by treating wood pulp or cotton linters with alkali and monochloroacetic
acid. It occurs as a white- or cream-colored powder or granules.
Carcinogenicity
Sarcomas were produced at the
site of repeated subcutaneous injection of aqueous solutions of carboxymethylcellulose. It should be noted, however, that
massive doses were given and therefore there must have been
considerable local trauma.
Check Digit Verification of cas no
The CAS Registry Mumber 9000-11-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 9000-11:
(6*9)+(5*0)+(4*0)+(3*0)+(2*1)+(1*1)=57
57 % 10 = 7
So 9000-11-7 is a valid CAS Registry Number.
