Propyl Gallate SDS MSDS Sheet of Manufacturers
Propyl Gallate, or propyl 3,4,5-trihydroxybenzoate is an ester formed by the condensation of gallic acid and propanol. Since 1948, this antioxidant has been added to foods containing oils and fats to prevent oxidation. As a food additive, it is used under the E number E310. Propyl gallate is an antioxidant. It protects against oxidation by hydrogen peroxide and oxygen free radicals. Propyl gallate is used to protect oils and fats in products from oxidation; it is used in foods, cosmetics, hair products, adhesives, and lubricants. Propyl Gallate is a generally recognized as safe (GRAS) antioxidant to protect fats, oils, and fat-containing food from rancidity that results from the formation of peroxides.
Propyl Gallate has CAS Number 121-79-9

Ph Eur --- C10H12O5 --- 212.2 --- 121-79-9
Action and use: Antioxidant.
DEFINITION
Propyl gallate contains not less than 97.0 per cent and not more than the equivalent of 103.0 per cent of propyl 3,4,5-trihydroxybenzoate, calculated with reference to the dried substance.
CHARACTERS
A white or almost white, crystalline powder, very slightly soluble in water, freely soluble in ethanol (96 per cent). It dissolves in dilute solutions of alkali hydroxides.
IDENTIFICATION
First identificationıB.
Second identificationıA, C, D.
A. Melting point: 148C to 151C.
B. Examine by infrared absorption spectrophotometry.
C. Examine the chromatograms obtained in the test for gallic acid.
D. Dissolve about 10 mg in 10 ml of water by heating to about 70C. Cool and add 1 ml of bismuth subnitrate solution. A bright yellow precipitate is formed.
TESTS
Appearance of solution: Dissolve 1.0 g in ethanol (96 per cent) and dilute to 20 ml with the same solvent. The solution is clear and not more intensely coloured than reference solution.
Gallic acid: Examine by thin-layer chromatography.
Total chlorine: Mix 0.5 g with 2 g of calcium carbonate. Dry and ignite at 700 ± 50C. Take up the residue with 20 ml of dilute nitric acid and dilute to 30 ml with water. 15 ml of the solution, without further addition of dilute nitric acid, complies with the limit test for chlorides (200 ppm).
Chlorides: To 1.65 g add 50 ml of water. Shake for 5 min. Filter. 15 ml of the filtrate complies with the limit test for chlorides (100 ppm).
Zinc: Not more than 25.0 ppm of Zn, determined by atomic absorption spectrometry
Heavy metals: 2.0 g complies with limit test C for heavy metals (10 ppm). Prepare the reference solution using 2 ml of lead standard solution (10 ppm Pb).
Loss on drying: Not more than 0.5 per cent, determined on 1.000 g by drying in an oven at 105C.
Sulphated ash: Not more than 0.1 per cent, determined on 1.0 g.

DESCRIPTION
Propyl Gallate occurs as a fine, white to nearly white powder. It is slightly soluble in water and freely soluble in alcohol and in ether.
Function: Antioxidant.
Identification: Place about 5 g of sample and several boiling chips into a 500-mL round-bottom flask, connect a water-cooled condenser to the flask, and introduce a steady stream of nitrogen into the flask, maintaining the flow of nitrogen at all times during the remainder of the procedure. Pour 100 mL of 1 N sodium hydroxide through the top of the condenser, heat the solution to boiling, boil for 30 min, and cool. Place the round-bottom flask in an ice bath, and slowly, with occasional swirling, add dilute sulfuric acid (10%) until a pH of 2 to 3 is obtained (using pH paper). Filter the precipitate through a sintered-glass crucible, wash with a minimum amount of water, and dry at 110C for 2 h. The gallic acid so obtained melts at about 240C with decomposition.
Assay: Not less than 98.0% and not more than 102.0% of C10H12O5 after drying.
Lead: Not more than 1 mg/kg.
Loss on Drying: Not more than 0.5%.
Melting Range: Between 146C and 150C.
Residue on Ignition: Not more than 0.1%.

Barter
They who love thee on this earth, keep calling on thee and chanting thy beads
Lest thou forgetest.
They assign the credit of their hard work to your blessings
They keep you amused.
They come to thy temple with baskets of fruits, as if you were a glutton
They deny the same to their children.
They offer you milk for a bath and burn the ghee
They hardly understand the meaning of it.
They bring gold and diamonds. They come with beating of drums
They love to advertise their offerings.
They offer you a small bribe as advance for booty, called lottery
They love to dream.
I do not bow down at your door
I do not bargain for booty
Your promise of the heaven does not lure me
Your hell-fire does not scare me
I do not even know the proper method of prayer
I do not offer any thing to you
Ages have gone by and I have not seen you my lord
Yet my love for you keeps waiting for you.
