PG is available (though often only by special order from any full-service Pharmacist. The cost varies from $5 to $8 per pint. Pharmacologically, it's used as a solvent for oral and injectable drugs.... It also has many uses as a chemical solvent, as well as being used in many cosmetics. PG is also available from many feed-stores, as it is used as a feed additive and a medical treatment for livestock.

Propylene glycol is an emollient used in many types of medical care products, including those applied to the skin or taken internally. Propylene glycol is found in medical products such as cough syrups and skin care products. It is safe and imparts unique attributes when formulated into such products.

Propylene Glycol is a solvent, but not an alcohol. Like cetyl alcohol, it is a moisturizer for skin and hair. It is used to preserve the quality of the herbal extracts, and it also attracts and holds moisture in skin and hair.

Propylene Glycol is a non-toxic, non-comedogenic (water based) ingredient. It functions as a humectant / skin-conditioning agent and is derived from yeast. There is no data to support carcinogenicity, despite a considerable amount of misinformation floating around the Internet.

This ingredient is on the Food and Drug Administration's GRAS ("generally recognized as safe") list of ingredients. It is also recognized as a safe ingredient by the World Health Organization. We feel confident it is safe. The propylene glycol that we use can be found in many other consumer products, like foods, pharmaceuticals, moisturizers, and skin care products. For more detailed information on this ingredient, please review the propylene glycol ingredient fact sheet.

from cosmetics and household detergents to paints and automotive brake fluids." http://www.dow.com/propyleneglycol/index.htm Incomplete evaluations do not mean that a chemical is free from "human carcinogenic potential." -- barb

Propylene glycol enables our deodorants to be applied smoothly in a stick form and helps to stabilize the base of anti-microbial plant ingredients. We have researched glycerin as a substitute, and found that the glycerin acts as a moisture binder that encourages bacterial growth, which causes odor. Earth Science prides itself on making gentle products that are suitable for a wide range of skin types and sensitivities. Many of our loyal customers consider themselves chemically sensitive.

Ethylene glycol and propylene glycol are chemically similar. Ethylene glycol has the chemical formula C2H6O2. Propylene has the chemical formula C3H8O2. Ethylene glycol has a slightly higher boiling point than propylene glycol. Ethylene glycol is less expensive to produce and is more widely used. Propylene glycol is less toxic. Both propylene glycol and ethylene glycol have similar biodegradability and will eventually break down into nontoxic byproducts.

Propylene glycol is much different than ethylene glycol. The term “glycol” actually refers to organic chemical structures that contain twin hydroxyl groups on neighboring carbon atoms. This common functional group is present in many different kinds of molecules. For example, all food carbohydrates contain glycol groups. Ethylene glycol is a toxic glycol used extensively in aqueous cooling systems (such as automotive “antifreeze” to prevent freezing in cold weather).

Tell your supplier to include corrosion inhibitors to protect copper and iron. Also, make sure they add a colorant to the glycol so that any leakage/spillage can be detected.

Propylene glycol is an ingredient used in numerous cosmetics and toiletries. It is also used as a powerful solvent to prevent creams from drying out. Propylene glycol is a petrochemical derivative and has been shown to cause allergies.

The results will be less than 1 color block conservative. Ethylene Glycol provides slightly higher freeze protection at like concentrations, and therefore contributes to a lower freeze point protection. Differences of less than 1 color block will result.

Raw Water Cooled Engines - Propylene glycol RV antifreeze with a rust inhibitor is approved for use in the raw water cooling system for cold weather storage purposes ONLY. Fresh Water Cooled (closed cooled) Engines ? If your engine is equipped with a closed cooling system, you should always use an appropriate mixture of Sierra Brand propylene glycol antifreeze and water in this system. Make sure to check the mixing ratio on the anti-freeze container.

Ethylene glycol and propylene glycol are chemically very similar and can be mixed without harming the cooling system. Ethylene glycol does have better heat transfer properties than propylene glycol. Adding propylene glycol does not make the ethylene glycol less toxic. No, it is never OK to neglect cooling system maintenance. Scale buildup and corrosion in radiators, for example, can cause overheating problems or radiator failure.

These ingredients are all emulsifiers that help to absorb moisture into the skin. They are widely used in the cosmetic industry and there is no data to support a connection to steroids.

No. The Repairing Lotion contains very low concentration levels of Propylene Glycol, well below the threshold.

Propylene Glycol, the base fluid of Engine Ice Hi-Performance Coolant TM, meets or exceeds all ASTM, SAE, Government and Manufacturers standards. It also has NO statutes or health warnings from the Clean Air Act Amendments (CAAA), CERCLA (Superfund), Superfund Amendments & Reauthorization Act (SARA), Occupational Health & Safety Administration (OSHA), American Conference of Governmental Industrial Hygienists (ACGIH), Federal Health & Safety Administration (FHSA).
