Natural Aroma Chemicals & Isolates

Buchu Sulphur Fractions

Buchu Sulphur Fractions

For cases in which the aroma contribution of buchu mercaptan and/or buchu thioacetate are sought in a flavour/fragrance formulation, without the added aromas of other components of the oils, or for when the amount of pulegone in any given formulation containing buchu oils need to be reduced, Puris produces a line of specialized and customized natural Buchu sulphur fractions from either A. betulina and/or A.crenulata oils using only sophisticated physical means of separation. The result is a potent blend of buchu mercaptan and/or buchu thioacetate with other remaining compounds that occur naturally in the oils, providing a natural and authentic flavour profile for these compounds. These fractions are especially well suited to use in flavour and fragrance formulations in which intense black currant, catty, berry-like & exotic qualities are sought.

Buchu Mercaptan, Natural

Buchu Mercaptan, Natural

8-Mercapto-p-menthan-3-one, otherwise known as “buchu mercaptan” is a unique character impact compound found in nature only in buchu oil. Widely used as a flavouring material for black currant aromas and as a general tropical or exotic aroma enhancer, this compound, in the unique isomer ratio found only in nature is offered as FDA/EU natural by Puris.  

Buchu Thio Acetate, Natural

Buchu Thio Acetate, Natural

Closely related to buchu mercaptan, buchu thio acetate, or 8-acetylthio-p-menthan-3-one, isolated as a natural fraction in high purity from A. crenulata oil, has similar aromatic properties to buchu mercaptan, but offers greater chemical stability and shelf life, and longer fixation than its related mercaptan. Although similar in aroma to buchu mercaptan, its aroma profile tends more to the exotic and fruity rather than the characteristic catty black currant note buchu mercaptan provides. 

Diosphenol, Natural

Diosphenol, Natural

Crystallized directly from A. betulina (diosphenol chemotype) essential oil and dried in vacuo, diosphenol crystals (>98% pure), also known as “buchu camphor” provide a distinct natural woody, fruity, minty, camphoraceous and cooling aroma to any flavour or fragrance aroma it is used in.  

Buchu Pulegone Fraction, Natural

Buchu Pulegone Fraction, Natural

Whether for use as a flavouring material, or as raw material in asymmetric organic syntheses,  Puris’s buchu pulegone fraction consistently meet the highest chemical and olfactory standards for this material.

Phenethyl Alcohol (Phenyl ethyl alcohol/2-Phenylethanol)

Phenethyl Alcohol (Phenyl ethyl alcohol/2-Phenylethanol)

Our natural Phenethyl alcohol is manufactured using state-of-the-art biofermentation techniques on-site at Puris’s new biotech plant dedicated to this process. This plant delivers the highest quality and purity grades of this widely used aroma chemical. Since all organisms involved in this process occur naturally and only the highest grade natural raw materials are employed, this material is classified as strictly non-GMO and EU/FDA natural.
