Propylene glycol also has other names, including: Sometimes people confuse it with ethylene glycol. It is a humectant, meaning it binds well to water, making it a good hydrating agent and solvent to aid penetration of other ingredients. Propylene glycol is a synthetic food additivethat belongs to the same chemical group as alcohol. For this reason propylene glycol is often preferred over ethylene glycol, as it is low enough in . Side by Side Comparison Dipropylene Glycol vs Propylene Glycol in Tabular Form The Skin Deep ingredient hazard score, from 1 to 10, reflects known and suspected hazards linked to the ingredients. The same thing happened to me! Nothing was truly helping until I tried vaping Sativa. Propylene glycol isn't used in the same way as butylene glycol. [39][40], Toxicity generally occurs at plasma concentrations over 4g/L, which requires extremely high intake over a relatively short period of time, or when used as a vehicle for drugs or vitamins given intravenously or orally in large bolus doses. References:Johnson, W et al. [43], The potential for long-term oral toxicity is also low. Pentylene Glycol, 1,2-Hexanediol and Caprylyl Glycol are 1,2-glycol compounds that vary only by the number of carbons. Acidosis means your body cant remove the acid as fast as it should, leading to toxicity. It does not store any personal data. It is soluble in many solvents, including water, acetone, chloroform, etc. Propylene glycol skin sensitization occurred in patients sensitive to a number of other concomitant positive allergens, most common of which were: Myroxylon pereirae resin, benzalkonium chloride, carba mix, potassium dichromate, neomycin sulfate; for positive propylene glycol reactions, the overall median of 5 and mean of 5.6 concomitant positive allergens was reported. Every once in a while there have been reports on allergic reactions that still today are circulated although said reactions obviously were due to contaminations.

The number one difference between the two glycols is that ethylene glycol is toxic and propylene glycol is not, allowing propylene glycol to be purchased as food grade in addition to the technical or industrial grade. All of this is and has been frustrating. [30][31][32] Vitamin E acetate has also been identified in this controversy. Manufacturing Propanediol produces approximately 40% fewer greenhouse gasses than manufacturing of Propylene Glycol according tolife cycle analysis from design data by Dupont Tate & Lyle, Propanediol has a low potential to irritate or sensitize skin and the potential for these effects are lower that Propylene Glycol. All skin types except those that have an identified allergy to it. Propylene glycol is a colorless, nearly odorless, thick liquid. It also helps improve the texture of skin care formulas and has mild preservative properties when used in amounts between 1-5%. I ended up going to a GI doctor and he did an exploratory surgery on me and couldnt see anything significant but I had told him about my vaping and he suggested I stopped. Though both are used in the cosmetics industry, dipropylene glycol is the preferred fragrance carrier oil for a number of reasons. [44] Because of its low chronic oral toxicity, propylene glycol was classified by the U. S. Food and Drug Administration as "generally recognized as safe" (GRAS) for use as a direct food additive, including frozen foods such as ice cream and frozen desserts. Are all glycols the same? Propanediol is derived from corn while propylene glycol is found from petrochemicals. It's more popular as an emulsifier, anti-caking agent, and texturizer in your food.

These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Theres been quite a bit of research into PG, and the results are not comforting. There are two main types of glycol used for this function: ethylene and propylene. Propylene glycol is 1,2-propanediol, but there is also 1,3-propanediol that doesn't have the same sensitizing effects and is often used as a replacement for propylene glycol. It is a solvent for food colors and flavors, and in the paint and plastics industries. [15], The freezing point of water is depressed when mixed with propylene glycol. I believe soybean oil and sunflower oil may also have traces of it but Im not sure. Therefore, propylene glycol is considered as not persistent in the environment. Methyl ethyl glycol. In most formulations, the concentration of pentylene glycol will range from 0.001-5%. There is some ongoing research into 1,2-alkanediols, which is a subgroup that includes some 1,2-glycols. the good: Pentylene glycol helps to stabilize and thicken products. Talking to eachother helps! [52][53][54], Propylene glycol has not caused sensitization or carcinogenicity in laboratory animal studies, nor has it demonstrated genotoxic potential.[55][56]. Its chemical formula is CH3CH(OH)CH2OH. Normally, such time-frame is limited to 1590 minutes, depending on the severity of snowfall and outside air temperature. Skin issues like irritation and sensitivity problems are noticed less during the use of propanediol. Sometimes, we call this substance an alpha-propylene glycol to easily distinguish it from propane-1,3-diol. CAS Number : 5343-92-. It's similar to propylene glycol (which has 3 carbon atoms instead of 4) and glycerol (which has 3 carbon atoms, but with an additional alcohol group). Propylene glycol (1, 2- propanediol) is an organic compound (a diol alcohol) and is a tasteless, odorless and colorless clear oily liquid. For anyone worried about this, it may be worth asking the company which form of propanediol they use in their products. Most reported cases of propylene glycol toxicity have resulted from propylene glycol used as a diluent for intravenous administration of benzodiazepines (Kraut and Kurtz 2008). It is the most common moisture-carrying vehicle other than water itself and helps prevent moisture loss in products as well as binding to moisture and holding it to the skin. It occurs as a colourless liquid and is odourless. It has practically no taste ( 1 ). The best way to protect yourself is to avoid products that contain the substance. He hardly eats. It is a colorless, odorless, slightly syrupy liquid that is a bit thicker than water. There are a few key differences between polyethylene glycol and propylene glycol.

Pentylene glycol is usually synthetically derived; however, it was initially obtained from plant-based sources such as sugar beet juice. However, the molecular structure and chemical composition of each is very different. What is propylene glycol used for? Propylene glycol.". All glycols are a type of alcohol, and butylene and propylene glycol have a similar molecular shape. After about 3 months of doing so I became very sick. Three-carbon deoxysugars are also precursor to the 1,2-diol. [8] Further purification produces finished industrial grade or USP/JP/EP/BP grade propylene glycol that is typically 99.5% or greater. 1. Industrially, propylene glycol is mainly produced from propylene oxide (for food-grade use). Compare the Difference Between Similar Terms. Propylene glycol is very useful in the production of many polymer materials. [22], When used in average quantities, propylene glycol has no measurable effect on development and/or reproduction on animals and probably does not adversely affect human development or reproduction. Hi! Because propylene glycol is derived from petroleum, many have concerns that it is carcinogenic and can be toxic when used in skincare.
