Alpha-pinene is the major constituent of turpentine (about 80%). It exists in levogyre form in European turpentine and in dextrogyre form in turpentine found in North-Americans. Sensitization occurs mainly in painters, polishers, and varnishers, and in those in the perfume and in the ceramics industry.
