Description and Uses

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