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.

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 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.

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.

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.

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

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.

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 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).

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.

Most patients, even those who are responding well to therapy, would like to make the Vitiligo less obvious. Many find that a combination of cosmetics effectively deemphasizes their skin disorder. Patients who are interested in dyes and stains should consult a dermatologist for the names of suitable commercial products. [top of page]

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.

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).

Strict sanitation and sterilization guidelines are followed. A prescription of Zoviraz is essential for those with a history of cold sores when considering permanent lip color. Patch tests are available for those concerned. There are no known allergic reactions to the pigments, but few cases have been reported from red colors. There can be allergic reactions to the cains used in the topicals. In most cases discomfort is at a minimum.

Only a handful of people have reported minor problems around the eye area and no problems around the lip or brow area. Even in those rare cases when redness and edema occurred, it did not cause any permanent damage. Test studies have proven that the microscopic “iron” particles in pigment are too insignificant to react as true metal pieces but rather are more accurately compared with “metals” which already exist microscopically in our bodies.

No. We have already announced that no more animals will be used in this country for the testing of cosmetics ingredients or finished products.

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 1 color block will result.

The FDA has approved Antizol for use in adults only; however, there are published reports of Antizol use in children using adult dosing guidelines.

We prefer that our companies sign the Safe Cosmetics Act, but not all are signers yet. I think we have >85-90% signers...and growing. Our purity criteria is more strict than the Compact for Safe Cosmetics requires, meaning that just because a company signs the compact - it does not mean that their products meet our criteria.
