	humidifier liquid
		Propylene glycol is a colorless innocuous liquid, which has two extremely favorable characteristics for its use in humidors.
		Secondly, propylene glycol forms a thin layer on the surface of the humidifier, which absorbs humidity at humidity levels of over 70% and which emits humidity at humidity levels below 70%.
		Propylene glycol is also known as 1.2 Propanediol.

		Propylene is a major commodity in the petrochemicals industry.
		Propylene glycol is considerably less toxic than ethylene glycol.
		This is because while propylene glycol is metabolized by the body into lactic acid, which occurs natually as muscles are excercised, ethylene glycol is metabolized into oxalic acid, which is toxic.

		Propylene glycol esters of fatty acids are mixtures of propylene glycol mono- and diesters of saturated and unsaturated fatty acids derived from edible oils and fats.
		The true propylene glycol content (in g/100 g of esters) is equal to the apparent propylene glycol content (in g/100 g of esters) minus 1.65 x the glycerol content (in g/100 g of esters).
		When calculating the total content of propylene glycol monoesters in the sample the response factor of propylene monostearate is used for all propylene glycol monoesters in the sample.

	Propylene glycol.
		In the cosmetic industry, propylene glycol is used in very small amounts to keep products from melting or freezing in extreme temperatures and assists the active ingredients in a product to penetrate the skin.
		Propylene glycol further enhances the performance of Sodium PCA in absorbing and retaining moisture in the skin.
		Only minute amounts of propylene glycol are added to our cosmetic preparations, which are nowhere near the estimated acceptable daily intake of 25 mg per kg as established in the 17th Report of the Joint FAO/WHO Expert Committee on Food Additives, 1974.

	Analyst Summer 2003 - Which to Use: ...
		The ability of both ethylene and propylene glycol to lower the freezing point of water, together with their relatively low vapor pressure and high boiling points, constitute the most important physical properties of these compounds.
		Propylene glycol solutions become considerably more viscous than ethylene glycol solutions at low temperatures; thus, their use in industrial systems operating in the range of 0ºF or below should be carefully evaluated with respect to pumping requirements.
		Propylene glycol solutions on the other hand are not particularly well suited for the determination of glycol content by gravity measurement.

	Propylene glycol (PIM 443)
		The toxicity of propylene glycol is mainly due to the parent compound and not to its metabolites.
		Propylene glycol may cause hypotension; bradycardia, and QRS and T abnormalities on the ECG; arrhythmia and cardiac arrest; and serum hyperosmolality and lactic acidosis (Karliner, 1967; Demey et al, 1988).
		Since the metabolites of propylene glycol are less toxic than the parent substance, inhibition of the metabolism of propylene glycol by ethanol or 4-methyl pyrazole is unnecessary.

	Cigars: using propylene glycol
		As a last resort I purchased a propylene glycol solution and have been using it for the past 2 days it did bring it up to 70 but I have read not to use the solution in place of water for a long period of time is this true.......thx in advance for any info
		Propylene Glycol can pick up particles in the air (such as smoke) and be less "potent" (or even diminish) over time so it's best to change it every 12 to 18 months just to keep things "fresh".
		Sometimes a low humidity level could be the result of a defective humidor or hygrometer so before you begin to use a propylene glycol solution, make sure your hygrometer is properly calibrated and the humidor is free of any construction flaws or defects that would let the humidity out.
