Hydroxyethyl Cellulose USP NF Grade Specifications:
Cellulose, 2-hydroxyethyl ether CAS 9004-62-0
UNII: 8136Y38GY5
DEFINITION
Hydroxyethyl Cellulose is a partially substituted poly(hydroxyethyl) ether of cellulose. It is available in several grades, varying in viscosity and degree of substitution, and some grades are modified to improve their dispersion in water. It may contain suitable anticaking agents.
IDENTIFICATION
A.
Sample solution: 1 g in 100 mL of water.
Analysis: Stir the Sample solution.
Acceptance criteria: It dissolves completely to produce a colloidal solution that remains clear when heated to 60°.
B.
Sample: 1 mL of the solution from Identification test A.
Analysis: Place the Sample on a glass plate and allow to evaporate.
Acceptance criteria: A thin, self-sustaining film is formed.
C.
Sample solution: 1 in 2000
Analysis: To 1 mL of the Sample solution add 1 mL of phenol solution (50 mg/mL), then add 5 mL of sulfuric acid, shake, and allow to cool.
Acceptance criteria: The color of the solution becomes orange.
Residue on Ignition: NMT 5.0%
Lead: NMT 10 µg/g
pH: 6.0 to 8.5 in 10 mg/mL solution
Loss on Drying: NMT 10.0%. Dry at 105C for 3 h.
Viscosity - Capillary Methods or Viscosity - Rotational Methods: When determined at the concentration and under the conditions specified in the labeling, its viscosity is NLT 50% and NMT 150% of the labeled viscosity, where stated as a single value, or it is between the maximum and minimum values, where stated as a range of viscosities.
Hydroxyethylcellulose BP Ph Eur Grade Specifications:
CAS 9004-62-0
Action and use: Excipient.
DEFINITION
Partly O-(2-hydroxyethylated) cellulose.
CHARACTERS
Appearance: White, yellowish-white or greyish-white powder or granules.
Solubility: Soluble in hot and cold water giving a colloidal solution, practically insoluble in acetone, in ethanol (96 per cent) and in toluene.
IDENTIFICATION
A. Heat 10 mL of solution S (see Tests) to boiling. The solution remains clear.
B. To 10 mL of solution S add 0.3 mL of dilute acetic acid and 2.5 mL of a 100 g/L solution of tannic acid. A yellowish-white, flocculent precipitate is formed which dissolves in dilute ammonia.
C. In a test-tube about 160 mm in length, thoroughly mix 1 g with 2 g of finely powdered manganese sulfate. Introduce to a depth of 2 cm into the upper part of the tube a strip of filter paper impregnated with a freshly prepared mixture of 1 volume of a 200 g/L solution of diethanolamine and 11 volumes of a 50 g/L solution of sodium nitroprusside, adjusted to about pH 9.8 with 1 M hydrochloric acid. Insert the tube 8 cm into a silicone-oil bath and heat at 190-200C. The filter paper becomes blue within 10 min. Carry out a blank test.
D. Dissolve 0.2 g completely, without heating, in 15 mL of a 700 g/L solution of sulfuric acid. Pour the solution while stirring into 100 mL of iced water and dilute to 250 mL with iced water. In a test-tube, mix thoroughly while cooling in iced water 1 mL of the solution with 8 mL of sulfuric acid, added dropwise. Heat on a water-bath for exactly 3 min and immediately cool in iced water. While the mixture is cold, carefully add 0.6 mL of ninhydrin solution and mix well. Allow it to stand at 25°C. A pink colour is produced immediately and does not become violet within 100 min.
Solution S: Disperse a quantity of the substance to be examined equivalent to 1.0 g of the dried substance in 50 mL of carbon dioxide-free water. After 10 min, dilute to 100 mL with carbon dioxide-free water and stir until dissolution is complete.
pH: 5.5 to 8.5 for solution S.
Apparent viscosity: 75 per cent to 140 per cent of the value stated on the label.
Chlorides: Maximum 1.0 per cent.
Nitrates: Maximum 3.0 per cent (dried substance), if hydroxyethylcellulose has an apparent viscosity of 1000 mPa⋅s or less and maximum 0.2 per cent (dried substance), if hydroxyethylcellulose has an apparent viscosity of more than 1000 mPa⋅s.
Glyoxal: Maximum 20 ppm.
Ethylene oxide: ethylene oxide: maximum 1 ppm.
2-Chloroethanol: 2-chloroethanol: not more than 0.5 times the area of the peak due to 2-chloroethanol in the chromatogram obtained with reference solution (b) (10 ppm).
Loss on drying: Maximum 10.0 %
Sulfated ash: Maximum 4.0 %
