What Benzyl Benzoate does

Gives products a mild, sweet scent
Helps scent blend evenly and last longer
Helps oil-based ingredients mix in

Benzyl benzoate is an ester, a molecule made by joining benzyl alcohol and benzoic acid. It occurs naturally in some plants, such as ylang-ylang, but most supply used in products is made in a lab. Its scent is mild and sweet.

In formulas, it works mainly as a fragrance ingredient. It also acts as a solvent, helping oil-loving ingredients mix into water-based products. It is thin and light, so it spreads easily. It is often found in shampoos, dry shampoos, sunscreens and baby products.
