Names: True lavender, garden lavender, or narrow-leaved lavender (L. angustifolia), broad-leaved lavender, Portuguese lavender and aspic lavender (L. latifolia)
Botany: Lavenders are aromatic evergreen sub-shrubs with linear or lance-shaped leaves. It grows up to 0.9 m high. They are native to the Mediterranean region, but are cultivated elsewhere (France is the major producer). The parts used are the fresh flowering tops from which the essential oils are obtained by steam distillation and extracts by solvent extraction.
Biochemistry: Lavender contains 0.5-1.5% volatile oil, tannin, coumarins, flavonoids (e.g. luteolin), triterpenoids (e.g. ursolic acid), and others.
Lavender oil has been reported to contain more than 100 components, including linalool, linalyl acetate, lavandulyl acetate, and others. It contains high concentrations of linalyl acetate but only traces of 1.8-cineole and camphor, while spike lavender oil contains large amounts of 1.8-cineole and camphor with only small amounts of linalyl acetate. The linalool concentration is usually higher in spike lavender oil than in lavender oil.
Lavandin is reported to have a higher volatile oil content than lavender and spike lavender. Due to its hybrid nature, the composition of its essential oil is much more variable than either of its parents.
Ursolic acid, also known as urson, prunol, micromerol and malol, is a pentacyclic triterpenoid compound that naturally occurs in lavender and many other plants. Ursolic acid and its alkali salts (potassium or sodium ursolates) were formerly used as emulsifying agents in cosmetic preparations. Its anti-inflammatory, anti-tumour (skin cancer), and antimicrobial properties make it useful in cosmetic applications. Ursolic acid may be of relevance in hair tonics to encourage hair growth.

All types of lavender products (especially essential oils) are used as a fragrance ingredients (some extensively) in cosmetic products, including soaps, detergents, creams, lotions, and perfumes (e.g., lavender waters and other colognes), spike lavender oil being more extensively used in soaps and detergents. The maximum use levels in perfumes are respectively 1.2, 1.0, and 0.8% reported for lavandin oil, lavender absolute, and spike lavender oil.
Lavender is irritating to skin and eyes. May cause sensitisation by skin contact.
Available data from one source indicate spike lavender oil, lavandin oil, and lavender absolute to be non-irritating and non-sensitizing to human skin, though lavender absolute has been reported elsewhere as a sensitizer. No human phototoxicity data were reported.
One source reports that the oil cause dermatitis and that more toxicological studies are needed.
