Cellulose,ethers,carboxymethyl ether,calcium salt Specification
The systematic name of thsi chemical is Cellulose, carboxymethyl ether, calcium salt. With the CAS registry number 9050-04-8, it is also named as Carboxymethylcellulose calcium. The classification codes are Pharmaceutic aid [tablet disintegrant]; TSCA Flag XU [Exempt from reporting under the Inventory Update Rule]. The other registry numbers are 111941-77-6, 52627-96-0, 57406-72-1 and 9060-76-8. It is white to pale yellow powder or fibrous substance which is almost insoluble in water and stable to heat, light, air and microbes.
Preparation of Cellulose,ethers,carboxymethyl ether,calcium salt: Adding calcium hydroxide to aqueous solution of sodium carboxymethylcellulose. And then we can get the product by precipitating.
Uses of Cellulose,ethers,carboxymethyl ether,calcium salt: It is used as thickener, binder, inviscid dispersant and collapsing agent. It also can promote dispersed in water of cocoa powder, instant coffee, soft drinks and other solid powder.
The following are the toxicity data which has been tested.
