Citral can be a colourless or pale, yellow liquid.
It has a strong, fresh odour of lemon peel, and we use it as a fragrance material.
It is widely found in essential oils we use, such as bergamot, cardamom, geranium, ginger, grapefruit, lemon, lemongrass, lime, neroli, sweet orange, petitgrain, rose and red thyme. It is found as a constituent of essential oils in many of our products.
Used as an ingredient, it gives a fresh, lemon odour to perfumes. In soap perfumery, it helps to develop rose notes.
