9032-42-2 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 9032-42-2 differently. You can refer to the following data:1. soluble in cold water, flocculates at elevated temperatures
2. A white, yellowish-white or grayish-white powder or granules, hygroscopic after drying.
Uses
Water retention aid, thickening agent, protective colloid, suspending agent, binder and stabilizer.Pharmaceutical Applications
Hydroxyethylmethyl cellulose is used as an excipient in a wide range of pharmaceutical products, including oral tablets and suspensions, and topical gel preparations. It has similar properties to methylcellulose, but the hydroxyethyl groups make it more readily soluble in water and solutions are more tolerant of salts and have a higher coagulation temperature.Safety
Hydroxyethylmethyl cellulose is used as an excipient in various oral and topical pharmaceutical preparations, and is generally regarded as an essentially nontoxic and nonirritant material.storage
Hydroxyethylmethyl cellulose is hygroscopic and should therefore be stored under dry conditions away from heat.Regulatory Status
GRAS listed. Included in nonparenteral medicines licensed in Europe (oral suspensions, tablets, and topical preparations).Check Digit Verification of cas no
The CAS Registry Mumber 9032-42-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,3 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 9032-42:
(6*9)+(5*0)+(4*3)+(3*2)+(2*4)+(1*2)=82
82 % 10 = 2
So 9032-42-2 is a valid CAS Registry Number.
