Description of pc593
Terpineol is a naturally occurring monoterpene alcohol that has been isolated from a variety of sources such as cajuput oil, pine oil, and petitgrain oil. There are four isomers, alpha-, beta-, gamma-terpineol, and terpinen-4-ol. beta- and gamma-terpineol differ only by the location of the double bond. Terpineol is usually a mixture of these isomers with alpha-terpineol as the major constituent.
Terpineols: alpha-, beta-, gamma-, and the 4-terpineol isomer; Terpineol has a pleasant odor similar to lilac and is a common ingredient in perfumes, cosmetics, and flavors. α-Terpineol is one of the two most abundant aroma constituents of lapsang souchong tea; the α-terpineol originates in the pine smoke used to dry the tea. (+)-α-Terpineol is a chemical constituent of skullcap.

What is pc593?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives.
- One such product is pc593 which has developed particularly rapidly in recent years. Do you know about pc593?
- The official answer: Pinoresinol has three isomers: alpha, beta and gamma. The α-pinoresinol is available in dextro, levorotatory and racemic forms. Dextro-α-pinoresinol is found in cardamom oil, sweet orange oil, orange leaf oil, neroli oil, jasmine oil, nutmeg oil; levorotatory α-pinoresinol is found in pine needle oil, camphor oil, cinnamon leaf oil, lemon oil, white lemon oil, rosewood oil. β-pinoresinol has cis and trans isomers (rare in essential oils). γ-pinoresinol is found as a free form or ester in cedarwood oil. Chemicalbook is present. In fragrances a mixture of α-pinoresinol is used. It is a colourless viscous liquid. It has a characteristic clove-like aroma. Boiling point 214-224°C, relative density d25250.930-0.936. refractive index nD201.482-1.485. insoluble in water, soluble in organic solvents such as ethanol and propylene glycol. α-pinoresinol is present in the leaves, flowers and stems of more than 150 plants. d-rotamers are present in the essential oils of cypress, cardamom, anise and neroli. l-rotamers are present in miscellaneous Lavender, Melaleuca alternifolia, Melaleuca alternifolia and cinnamon leaf essential oils. Biological activity α-pc593 was isolated from EucalyptusglobulusLabill and has Chemicalbook strong antibacterial activity against periodontal and caries-causing bacteria. α-pc593 has antifungal activity T. mentagrophytes, an activity that may lead to irreversible cell division. Production methods
- Made from isoprene and butenone by condensation reaction, then reacted with Grignard’s reagent; or from pinene in turpentine by the action of 30% sulphuric acid to produce a crystalline precipitate of hydrated terpene glycol, separated by dehydration, separation and distillation to obtain the finished product.
- Isolated and extracted from longleaf pine.
What’s the application of pc593?
Use A monostearyl alcohol. One of the antifungal active ingredients in the essential oil of Melaleuca alternifolia (tea tree).
