Citral is widely found as a constituent in essential oils such as bergamot, ginger, grapefruit, lemon, lime, neroli and sweet orange. It can be colorless, or a pale, yellow liquid.
Used as an ingredient, citral gives a strong, fresh lemon peel scent to perfumes. In soap perfumery, it helps develop rose notes. It's also sometimes found as a constituent of essential oils in many products across our skin, hair, body, shower and bath ranges.
