Propylene Glycol – Product Information
One of the most popular cosmetic ingredients, propylene glycol, is a clear, viscous liquid with a faintly bitter or slightly sweet taste. It serves as a solvent and wetting ingredient while absorbing moisture.
It is frequently utilized in creams, mouthwashes, antiperspirants, liquid makeup, and other products. Additionally, propylene glycol is used to manufacture e-cigarette vaping liquids as a flavor carrier.
Today, this chemical is available for research usage. Purerawz sells propylene glycol for research purposes only.
What is Propylene Glycol?
Propylene glycol is a water-absorbing synthetic liquid. Propylene glycol is also used to produce polyester compounds and as a base in de-icing solutions. Propylene glycol is even utilized as non-toxic antifreeze in the chemical, food, and pharmaceutical industries when leakage may result in contact with food.
Propylene glycol has been classified as a “generally recognized as safe” food additive by the Food and Drug Administration (FDA). It absorbs excess water and keeps certain medicines, cosmetics, and food products moist.
It is used to dissolve food colors and flavors in the paint and plastics industries. Propylene glycol is also used to make fake smoke or fog, which applies to firefighting training and theatrical productions.
Possible Applications of Propylene Glycol
Propylene Glycol in Food Industries
Propylene, precisely USP grade, has many properties advantageous to packaged foods. Food manufacturers widely use it as a food-grade additive to extend the shelf life of processed foods. [R]
Apart from being used as a preservative and flavor enhancer, propylene glycol has helped food manufacturers by becoming an emulsifier, texturizer, and processing aid to improve the appearance of food. [R]
Propylene Glycol in Pharmaceutical Industries
Propylene glycol is a common solvent in the pharmaceutical industry. This means that it dissolves other substances (usually solids) without altering their basic structure or composition. [R]
Propylene glycol is also used in drug formulations as a carrier. It can be formulated with active ingredients and delivered to the body through it. Finally, it is employed in the diluting and stabilization of pharmaceuticals. [R]
Propylene glycol can be found in various drugs, including capsules and tablets, topical creams and gels, and intravenous (injected) drugs. [R]
Propylene Glycol in Cosmetics
Propylene glycol is a widely used ingredient in cosmetic, personal care, and skincare products. It ranges between 26.4% and 37.8% of registered personal care products. [R]
Propylene glycol is a versatile substance that performs various functions in the product formulations containing it. Propylene glycol acts as a humectant, attracting moisture to the skin and hydrating and moisturizing it. [R]
It dissolves substances in a product formulation to properly mix and work together. It also serves as a vehicle for active ingredients. [R]
Propylene glycol is classified as an emollient because it forms an oily layer on the skin, preventing water loss and decreasing the thickness of cosmetic formulations and products. [R]
The lowest price of propylene glycol depends on the manufacturer’s offer.
Propylene Glycol in E-Cigarettes
Propylene glycol and vegetable glycerin are major components of the liquids (e-liquids) used in e-cigarettes. E-cigarettes convert propylene glycol into extremely small droplets to mimic smoke. [R]
It also serves as a carrier for nicotine and flavorings commonly found in e-liquids. [R]
Propylene Glycol in Antifreeze
Propylene glycol lowers the freezing point of water and water-based liquids, making it an antifreeze. Propylene glycol is a significant component of aircraft de-icers and is used to break up ice on airport runways. [R]
Because propylene glycol is non-toxic, it is frequently used as an antifreeze in food processing systems and water pipes connected to connecting hoses. [R]
How Does Propylene Glycol Work?
The absorption of propylene glycol from the gastrointestinal tract, and its elimination from the body follows first-order kinetics. In humans, clearance from blood is rapid, with a mean half-life of approximately two hours.
Pyrazine inhibits its metabolism, indicating a role for alcohol dehydrogenase in this process. It is easily converted into lactic and pyruvic acids after absorption and enters the general metabolic pool.
Propylene glycol is easily absorbed from the gastrointestinal tract and distributed throughout the body’s water. Because of intersubject variability in clearance, propylene glycol accumulation has been reported to differ significantly among people on a repetitive oral dosing schedule.
Safety and Side Effects
We do not recommend propylene glycol for human consumption. While propylene glycol is a great product, it is not suitable for everyone. When using a product containing propylene glycol, one may develop a rash in the following cases:
- have skin conditions such as eczema
- have an allergy history
- have delicate skin
Frequently Asked Questions
What is another name for propylene glycol USP?
Other names for propylene glycol include:
- trichloroethylene glycol
- MEEG stands for methyl ethyl glycol.
- Methylethylene glycol
Is propylene glycol harmful to humans?
The U.S. declares that propylene glycol is “generally recognized as safe.” Drug Enforcement Agency (DEA) (FDA 2017). For people aged 2-65, the FDA deems a daily dietary intake of 23 mg/kg of body weight to be safe (ATSDR 2008). [R]
What is the difference between propylene glycol and ethylene glycol?
The primary distinction between ethylene and propylene glycol is the degree of toxicity. Propylene glycol has relatively low toxicity, which is why it is also used in cosmetics and personal care items, but ethylene glycol is deadly and needs to be treated carefully to minimize exposure to humans and animals.
Can you use propylene glycol to age cigars?
To provide the ideal relative humidity for storing and aging cigars, propylene glycol must be combined with distilled water. A PG solution for humidors helps to stop mold and bacteria growth in your humidor and on the cigars, in addition to relative humidity.
