Propyl Hydroxybenzoate or Propyl Paraben SDS of Manufacturers
CAS Number 94-13-3 Propyl Hydroxybenzoate or Propyl Paraben, EINECS: 202-307-7, Molecular Weight: 180.2, Chemical Formula: C10H12O3
Propylparaben USP NF Grade Specifications Grade Specifications
C10H12O3 --- 180.20
Benzoic acid, 4-hydroxy-, propyl ester.
Propyl p-hydroxybenzoate CAS 94-13-3
Propylparaben contains not less than 98.0 percent and not more than 102.0 percent of C10H12O3.
Identification:
A: Infrared Absorption 197M .
B: Melting range: between 96C and 99C.
Color of solution: Dissolve 1 g in alcohol, dilute with alcohol to 10 mL, and mix (Propylparaben solution). This solution is clear and not more intensely colored than alcohol or a solution prepared immediately before use by mixing 2.4 mL of ferric chloride, 1.0 mL of cobaltous chloride, and 0.4 mL of cupric sulfate with 0.3 N hydrochloric acid to make 10 mL, and diluting 5 mL of this solution with 0.3 N hydrochloric acid to make 100 mL. Make the comparison by viewing the solutions downward in matched color-comparison tubes against a white surface.
Acidity: To 2 mL of Propylparaben solution prepared in the Color of solution test add 3 mL of alcohol, 5 mL of carbon dioxide-free water, and 0.1 mL of bromocresol green, and titrate with 0.10 N sodium hydroxide: not more than 0.1 mL is required to produce a blue color.
Residue on ignition: not more than 0.1%, determined on 1.0 g.
Related substances: To pass the test.

C10H12O3 --- 180.2 --- CAS 94-13-3
Action and use: Antimicrobial preservative.
DEFINITION
Propyl 4-hydroxybenzoate.
Content: 98.0 per cent to 102.0 per cent.
CHARACTERS
Appearance: White or almost white, crystalline powder.
Solubility: Very slightly soluble in water, freely soluble in alcohol and in methanol.
IDENTIFICATION
First identification A, B.
Second identification A, C, D.
A. Melting point: 96C to 99C.
B. Infrared absorption spectrophotometry. Comparison propyl parahydroxybenzoate CRS.
C. Examine the chromatograms obtained in the test for related substances.
Results: The principal spot in the chromatogram obtained with test solution (b) is similar in position and size to the principal spot in the chromatogram obtained with reference solution (b).
D. To about 10 mg in a test-tube add 1 ml of sodium carbonate solution, boil for 30 s and cool (solution A). To a further 10 mg in a similar test-tube add 1 ml of sodium carbonate solution; the substance partly dissolves (solution B). Add at the same time to solution A and solution B 5 ml of aminopyrazolone solution and 1 ml of potassium ferricyanide solution and mix. Solution B is yellow to orange-brown. Solution A is orange to red, the colour being clearly more intense than any similar colour which may be obtained with solution B.
TESTS
Solution S: Dissolve 1.0 g in alcohol and dilute to 10 ml with the same solvent.
Appearance of solution: Solution S is clear and not more intensely coloured than reference solution.
Acidity: To 2 ml of solution S add 3 ml of alcohol, 5 ml of carbon dioxide-free water and 0.1 ml of bromocresol green solution. Not more than 0.1 ml of 0.1 M sodium hydroxide is required to change the colour of the indicator to blue.
Related substances: Thin-layer chromatography to pass the test. (0.5 per cent).
Sulphated ash: Maximum 0.1 per cent, determined on 1.0 g.
Propylparaben FCC Food Grade Specifications
Propyl p-Hydroxybenzoate
C10H12O3 Formula weight 180.20
INS: 216 CAS 94-13-3
DESCRIPTION
Propylparaben occurs as small, colorless crystals or as a white powder. One gram dissolves in about 2500 mL of water at 25C, in about 400 mL of boiling water, in about 1.5 mL of alcohol, and in about 3 mL of ether.
Function: Preservative; antimicrobial agent.
REQUIREMENTS
Identification: Dissolve about 500 mg of sample in 10 mL of 1 N sodium hydroxide, and boil for 30 min, allowing the solution to evaporate to a volume of about 5 mL. Cool the mixture, and carefully acidify it with 2 N sulfuric acid. When the precipitate is cool, collect it on a filter, wash it several times with small portions of water, and dry it in a desiccator over silica gel. The liberated p-hydroxybenzoic acid melts between 212C and 217C.
Assay: Not less than 99.0% and not more than 100.5% of C10H12O3, calculated on the dried basis.
Acidity: Passes test.
Lead: Not more than 2 mg/kg.
Loss on Drying: Not more than 0.5%.
Melting Range: Between 95C and 98C.
Residue on Ignition: Not more than 0.05%.
