What it is
Dichlorobenzyl alcohol is a synthetic organic compound with antimicrobial properties. It belongs to the class of benzyl alcohol derivatives and is used primarily as a preservative in cosmetics and personal care products.
How it works
It works by disrupting the cell membranes of microorganisms like bacteria and fungi, causing them to die or stop multiplying. This keeps the product free from contamination during its shelf life.
Pros
Effective preservation
Helps prevent microbial contamination, keeping your products safe and fresh for longer.
Low irritation potential
At typical use levels, it rarely causes skin reactions, making it suitable for most skin types.
Cons and cautions
Synthetic origin
Not derived from natural sources, which may be a drawback for those seeking natural or organic formulations.
Possible mild sensitivity
A small number of people may experience mild irritation, especially with prolonged contact or on compromised skin.
Best for
- Anyone using products that need preservation
- People who prefer synthetic preservatives with a strong safety record
