CAS Number: 94-13-3, EINECS EC Number: 202-307-7, Molecular Formula: C10H12O3, Molecular Weight: 180.2

Propylparaben USP NF Grade
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.

Propyl Hydroxybenzoate BP Grade
Propylparaben
Propyl Parahydroxybenzoate, Ph Eur
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 identificationıA, B.
Second identificationıA, C, D.
A. Melting point: 96C to 99C.
B. Infrared absorption spectrophotometry. Comparisonıpropyl 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.

Polypropylene Glycol FCC Food Grade
CAS: 25322-69-4

DESCRIPTION
Polypropylene Glycol occurs as a clear, colorless or practically colorless, viscous liquid. It is an addition polymer of propylene glycol and water represented by the formula HO(C3H6O)n- C3H6OH, in which n represents the average number of oxypropylene groups. It is soluble in water and in such organic solvents as aliphatic ketones and alcohols, but it is insoluble in ether and in most aliphatic hydrocarbons.
Function: Defoaming agent.

REQUIREMENTS
Lead:Not more than 1 mg/kg.
Nominal Molecular Weight: Not less than 90.0% and not more than 110.0% of the labeled value.
pH: Between 6.0 and 9.0.
Propylene Oxide: Not more than 0.02%.
Residue on Ignition: Not more than 0.01%.
Viscosity: Passes test.
