Methylene Glycol

1. Definition Methylene Glycol:

Methylene Glycol, also known as formaldehyde, is a colorless, strong-smelling gas that is commonly used as a preservative in cosmetics. When dissolved in water, it forms a solution known as formalin, which is used to prevent the growth of bacteria and mold in various beauty products.

2. Use:

Methylene Glycol is primarily used in cosmetics as a preservative to extend the shelf life of products by inhibiting the growth of microorganisms. It is commonly found in shampoos, conditioners, lotions, and other personal care items to maintain their quality and prevent spoilage.

3. Usage Methylene Glycol:

While Methylene Glycol is effective at preserving cosmetics, it is important to note that it can be a skin irritant and allergen for some individuals. It is crucial to follow the recommended guidelines for safe usage, such as avoiding direct contact with the skin and eyes, as well as ensuring proper ventilation when using products containing formaldehyde.
