What Benzaldehyde does

Adds a sweet, bitter almond scent
Gives lip products a nutty flavor
Rounds out fragrance blends

Benzaldehyde is the main aroma compound in bitter almonds, and it also appears in apricot and cherry pits. Most of the benzaldehyde used in products today is made by chemical synthesis, which gives a steady, consistent supply.

Formulators use it in lip gloss to add a sweet, nutty smell and taste. It is a clear to pale yellow oily liquid that blends easily into oils and waxes. Left in air for a long time, it can slowly oxidize into benzoic acid, so sealed packaging helps keep it stable.

Good for

Suits people who like almond-scented or flavored lip products and tolerate fragrance ingredients well.

Frequently asked questions

Is benzaldehyde safe in lip gloss?

For most people, benzaldehyde is well tolerated at the small levels used in lip products. If you react easily to scents, do a patch test on your inner arm before using a new gloss often.

Does benzaldehyde go bad?

Keep the cap closed and store the product away from heat and sunlight. Air exposure is what slowly changes benzaldehyde into benzoic acid, and that can shift the scent over time.
