The Flammability of Vegetable Glycerin
Vegetable glycerin is classified as non-flammable, meaning it does not easily catch fire or support combustion in normal conditions. Unlike other flammable liquids, such as alcohol or gasoline, vegetable glycerin has a high flash point. The flash point is the lowest temperature at which a substance can produce enough vapor to ignite when exposed to an open flame or spark.
Due to its high flash point of approximately 177 degrees Celsius (350 degrees Fahrenheit), vegetable glycerin requires exposure to high heat or an open flame for ignition to occur. This makes it a safe ingredient to use in various applications, ranging from cosmetics and personal care products to food and pharmaceuticals.
Properties That Make Vegetable Glycerin Non-flammable
Several factors contribute to the non-flammable nature of vegetable glycerin:
- Low volatility: Vegetable glycerin has a low evaporation rate, meaning it does not easily convert into a gas or vapor. As a result, it does not release enough flammable vapor to sustain a flame.
- High boiling point: The boiling point of vegetable glycerin is approximately 290 degrees Celsius (554 degrees Fahrenheit). This high temperature requirement for vaporization further contributes to its non-flammable properties.
- No oxygen source: Vegetable glycerin does not contain any oxygen atoms in its chemical structure. Since oxygen is necessary to support combustion, the absence of oxygen in vegetable glycerin prevents it from being highly flammable.
Other Safety Considerations
While vegetable glycerin is considered non-flammable, it is essential to handle it with care and follow appropriate safety guidelines. Here are some general safety considerations:
- Storage: Store vegetable glycerin in a cool, dry place away from direct sunlight and sources of heat. Keep it tightly sealed in its original container to prevent contamination and evaporation.
- Dispensing: When dispensing or transferring vegetable glycerin, use appropriate containers that are resistant to corrosion and leakage. Avoid prolonged skin contact and eye exposure. In case of accidental contact, rinse with water immediately.
- Compatibility: Check the compatibility of vegetable glycerin with other substances in your intended application. While it is generally safe to use, certain chemicals or materials may react with glycerin under specific conditions, leading to potential hazards.
