    Propylene Glycol Buying Guide-FAQs about buying Propylene Glycol

    Buying propylene glycol is difficult since there are numerous factors to consider. However, you won’t need to worry—we’ll make it simpler for you to buy this chemical by providing key insights and data to assist you make a smart choice. Propylene glycol, a synthetic ingredient found in many cosmetics and food items, is safe in moderation. However, excessive doses and long-term use pose dangers. That’s where this tutorial helps. This buying guide discusses propylene glycol and pre-purchase considerations.

    propylene glycol in food

    Propylene glycol PG is a synthetic additive applied in foods and, most importantly, as a skincare ingredient. It is an organic compound classified as diol alcohol. Besides, it exists in the form of a clear, colorless hygroscopic liquid having a very faint sweet taste. Being totally free from volatile organic chemicals, non-toxic, and very moisturizing, it has far-reaching applications because of its mentioned properties. It has the most significant applied fields in foods and personal care products, such as humectants and preservatives. Propylene glycol is used as a solvent, flavor, color carrier, or extraction medium in the U.S. and E.U. It is regarded as generally safe for foods and cosmetics, with the exception of high concentrations that might cause skin irritations or an allergic response in some persons.
    Because miscibility and nonvolatility are its properties, along with multifunctionality, propylene glycol forms an intrinsic part of the food, health, medication, and cosmetic industries.

    Is propylene glycol flammable?

    Propylene glycol is considered non-flammable under typical handling conditions and does not burn readily like many other organic solvents. According to safety data sheets and chemical reference guides, pure propylene glycol has no flash point and poses a very low fire hazard. However, at extremely high temperatures exceeding 370°F (188°C), propylene glycol can generate flammable vapors which can be ignited with an open flame. This represents an uncommon scenario, as usual applications are well below this temperature threshold. Still, caution should be exercised when heating propylene glycol to very high temperatures, and adequate ventilation provided to avoid vapor accumulation. For the vast majority of uses, the high ignition temperature means propylene glycol can be considered non-flammable. It does not give off flammable fumes like other alcohols, nor sustain burning. So while not strictly non-combustible under extreme conditions, for practical purposes propylene glycol possesses very low flammability and is typically classified as a non-flammable solvent.

    Is propylene glycol safe?

    Propylene glycol is generally considered safe for use in food, cosmetics, and pharmaceuticals when exposure is at normal levels, though some controversy exists regarding its safety at high doses. Regulatory agencies, like the FDA, have declared propylene glycol GRAS—Generally Recognized as Safe—to be used as an approved food additive at the recommended maximum levels. Dermal exposure from cosmetics is considered to be non-toxic. Propylene glycol, however, might cause skin irritation, allergic reactions, or some other mild form of response in sensitive subjects, mostly with products that are applied to broken or inflamed skin. It is also feared that a highly high intake of propylene glycol from processed foods over a considerably long period could pose neurological or kidney problems, as shown in some studies on animals. However, the data is still relatively low in humans. However, some warnings advise against ingesting pure propylene glycol. While propylene glycol is entirely safe for most individuals if it is going to be used at recommended average levels in food and topical products, mitigation of overexposure in sensitive products may still be a prudent measure. Further research is required to establish the long-term impacts of cumulative low-dose exposure.

    Is propylene glycol antifreeze?

    While propylene glycol has some uses as an aircraft de-icing fluid, it should not be confused with the main components of automotive antifreeze which are much more toxic. Significant components of antifreeze are either ethylene glycol or methanol, both among the more toxic substances which, when taken in enough quantity, can be fatal. Propylene glycol is used in food additives, cosmetics, and medicinal humectants and is a safer antifreeze replacement.
    At such dilute levels, propylene glycol is rated GRAS or generally recognized as safe by the FDA. It’s misinformation to call it “anti-freeze” regarding approved food-grade propylene glycol.
    They are distinct chemical compounds with very different toxicities. So while industrial-grade propylene glycol has some niche uses for de-icing, it should not be mistaken for the active ingredient in the deadly antifreeze used in car radiators. The regulated food additive form has survived rigorous safety assessments for human consumption and cosmetic use.

    What foods contain propylene glycol?

    Propylene glycol is used as a food additive and processing aid in a wide variety of commonly consumed foods and drinks. As it retains moisture and helps incorporate flavors, propylene glycol is found in baked goods, sweetened beverages, dressings, ice creams, popcorn, and many other processed items. This humectant property makes this the additive of necessity in cakes, cookies, and muffins. Other uses for propylene glycol include emulsification and blending ingredients into foods, such as cocoa powder or nut butter. Flavor components of soft drinks, juices, and alcoholic beverages are uniformly dispersed with it. Since propylene glycol catches and retains water, its addition to ice cream and other products avoids icing.
    It often appears on ingredient lists of packaged foods under the codes E1520 or 57-55-6. While usage levels are considered safe, the ubiquity of propylene glycol across the food supply means most consumers regularly ingest small amounts from multiple sources in their diet without even realizing it. Reading labels remains the only way to monitor exposure from this quiet but common additive.

    What is propylene glycol made of?

    Propylene oxide produces petroleum- or bio-based alcohol, propylene glycol. The hydrolysis of water with propylene oxide under pressure and high temperature is the main industrial process. Propylene oxide may be regenerated using any petrochemical feedstock, for example, propane or bio-based propane, which will be produced by sugar fermentation. Therefore, maize, palm oil, and cane sugar will make food-grade propylene glycol. The best propylene glycol is always made by converting bio-propylene into propylene oxide using traditional petrochemical methods using hybrid renewable techniques. Propylene glycol, a petroleum-based chemical, results. Although marketed as organic, the bio-feed propylene glycol is thus heavily processed synthetically. The lesson is that all propylene glycol, whether from petroleum or bio-propylene, is produced via a multi-step industrial process.

    How bad is propylene glycol for you?

    Although propylene glycol has generally been considered safe for the most part, recently, a great deal of controversy has emerged regarding the possible health impact of widespread exposure to the substance. Pharmaceutical-grade propylene glycol was FDA-approved as GRAS and has been used in small amounts as a food and cosmetics stabilizer and humectant for years. However, sensitive people may have skin or eye discomfort at greater concentrations. Further concerns exist that propylene glycol in processed food might cause diabetes. All major regulatory bodies certify propylene glycol’s safety at legal amounts. Although the everyday risk of ingesting and dermal application is modest for most individuals, adverse responses to this component are always possible. Due to this, a long-term cumulative exposure study may be needed to confirm no harm, particularly for youngsters. Propylene glycol is an FDA-approved ingredient that poses no danger if supplied properly.

    Does propylene glycol cause cancer?

    No data proves it causes cancer. The FDA considers it safe for food, cosmetics, and pharmaceuticals. It should not cause cancer under normal settings. In toxicological trials on animals, propylene glycol did not promote tumors.

    It is also a popular food additive and topical component, thus extensive human exposure is unlikely to cause cancer. Long-term studies on extremely high chronic exposure have gaps, leaving problems unsolved.

    A few in-vitro studies have suggested biochemical effects on cells that may warrant further research. But overall, robust data from human studies and animal testing indicates propylene glycol is unlikely to be carcinogenic at typical dietary intake levels. No chemical is completely safe, however, there is no evidence connecting propylene glycol exposure to cancer or carcinogenicity. Such an absolute proof of its non-carcinogenicity may need further research.
