Glyceryl Palmitostearate or Glycerol Palmitostearate
CAS Number: 8067-32-1
Molecular Formula: C37H76O7
Molecular Weight: 633.0
Glyceryl Palmitostearate or Glycerol Palmitostearate
Glyceryl Palmitostearate FCC Food Grade:
DESCRIPTION
Glyceryl Palmitostearate occurs as a fine powder or waxy solid. It is a mixture of fatty acid glycerides, primarily glyceryl esters of palmitic and stearic acids. The waxy solid melts at about 55°. Glyceryl Palmitostearate is soluble in chloroform, but practically insoluble in water and in alcohol.
Function: Emulsifier.
REQUIREMENTS
Identification: Transfer about 100 mg of sample into a small, conical flask fitted with a suitable reflux condenser. Transfer 50 mg each of USP Palmitic Acid Reference Standard and USP Stearic Acid Reference Standard into a similar flask to serve as the Standard Solution. Treat the contents of each flask as follows: Add 5.0 mL of a solution prepared by dissolving 14 g of boron trifluoride in methanol to make 100 mL [commercial reagent, 14% w/v, may be used (Applied Science, or equivalent)]. Swirl to mix, and reflux for 15 min. Cool, transfer the reaction mixture with the aid of 10mLof chromatographic grade hexane to a 60-mL separator, and add 10 mL of water and 10 mL of saturated sodium chloride solution. Shake, allowthe mixture to separate, then drain and discard the lower, aqueous layer. Pass the hexane layer through 6 g of anhydrous sodium sulfate into a suitable flask. Concomitantly introduce a 1-_L to 2-_L portion of the filtered hexane solution from each of the two flasks into a gas chromatograph, or equivalent, and obtain the chromatograms. Use a gas chromatograph, or equivalent, equipped with a flame-ionization detector and a 1.5-m × 3-mm (id) column packed with 15% diethylene glycol succinate polyester on flux-calcined, acid-washed siliceous earth. Maintain the column at 165C. Set the temperatures of the inlet port and the detector to 210C. Use helium as the carrier gas. The retention times of the main peaks of methyl palmitate and methyl stearate obtained in the Sample Solution chromatogram correspond to those of the main peaks obtained from the Standard Solution. The ratio of the response of the main peaks to the sum of all the responses is between 0.42 and 0.55 for methyl palmitate, and between 0.43 and 0.55 for methyl stearate.
