Propylene Glycol Monoesters

Propylene glycol monoesters are made from propylene glycol, a synthetic compound. They are produced by reacting propylene glycol with fatty acids, often derived from vegetable oils. This process creates a mixture of monoesters and diesters.

Manufacturers use propylene glycol monoesters as emulsifiers and stabilizers in foods. They help ingredients like oil and water mix together smoothly, improving texture and preventing separation. They are commonly found in ice cream, baked goods, and other processed foods.

In the US, propylene glycol monoesters are generally recognized as safe (GRAS) by the FDA for use as emulsifiers and stabilizers. They are metabolized by the body similarly to fats. International bodies like JECFA have evaluated them, but no specific numeric limits are set. Evidence does not indicate adverse health effects at typical consumption levels.
