	NTP: Abstract for TR-240 - Propyl Gallate
		Propyl gallate is a white to nearly white odorless powder having a slightly bitter taste.
		The absence of this tumor in the high-dose female rat group reduces the likelihood that this tumor is related to propyl gallate administration.
		Under the conditions of this bioassay, propyl gallate was not considered carcinogenic for F344/N rats, although there was evidence of an increased proportion of low-dose male rats with preputial gland tumors, islet-cell tumors of the pancreas, and pheochromocytomas of the adrenal glands; rare tumors of the brain occurred in two low-dose females.

	Absorption enhancers such as e.g. bht, bha or propyl gallate patent invention
		These compounds have hydroxyl groups attached directly to the aromatic nucleus and an additional substituent in the position para to the OH group, and typically display antioxidant properties, which may or may not be related to their ability to act as permeation enhancers.
		Propyl gallate and other esters of gallic acid appear to be potent inhibitors of cytochrome P450, and it is claimed that sufficient propyl gallate can be introduced into a formulation to exert a significant effect without the need for solubilisation aids.
		However, the enzyme inhibitor mechanism of action described for propyl gallate, however, cannot be expected to enhance the bioavailability of macromolecules, since macromolecules are incapable of entering unaided into intestinal cells, and so would not come into contact with the endoplasmic reticulum where the enzyme is located.

	Propyl Alcohol in Cosmetics, Medications, and Cleaning Products
		Propyl alcohol is an antiseptic ingredient in many if not most cosmetic products: shampoo, cream rinse, hair spray, shaving lotion, body lotion, lipstick, deodorant, toothpaste, make-up, nail polish, and mouth wash. The purpose of this chemical is to inhibit microbial growths and extend shelf life.
		It is an ingredient in many medications such as Alka-Seltzer and aspirin; and unfortunately, it is also used as a solvent in the processing of some essential oils, which is why one wants to know as much as possible about the source and production of essential oils before buying them.
		Propanol or propyl alcohol is similar to the above except that it is drying.

	Restek Pharmaceutical Article - Simple, Optimized HPLC Analysis of Catecholamines
		Our intent with this analysis was to determine if an Allure™ PFP Propyl column, with its pentafluorophenyl propyl stationary phase, sufficiently increases retention for biogenic amines to allow an analysis without ion-paring or derivatization.
		Using this mobile phase and an Allure™ PFP Propyl column retention was suitable, as expected, and the analytes were separated (Figure 3).
		Because the Allure™ PFP Propyl provides optimum retention, a small percentage of organic modifier could also be included in the mobile phase.

	Patent 5962522
		Improved formulations of pharmaceutical compounds include propyl gallate to enhance the bioavailability of the active ingredient of the pharmaceutical compound.
		An object of this invention is to identify compositions with superior ability to increase drug bioavailability, particularly by increasing net drug absorption and/or decreasing drug biotransformation in the gut wall by inhibiting cytochrome P450 drug metabolism.
		One specific object of the present invention is to reduce inter-individual variability of the systemic concentrations of the active pharmaceutical compound, as well as intra-individual variability of the systemic concentrations of the pharmaceutical compound being administered.
