Creating Memorable Fragrances for our clients products is our passion
Billions of Consumers Everyday
The aroma of a soil after an immediate rain, that smell known as petrichor, stems from microscopic streptomycete bacteria in the soil that produce a compound called geosmin. These bacteria are abundant in soil and are among nature´s best chemists, as they make a wide range of molecules (called specialised metabolites) from which many antibiotics derive. Streptomycetes and their close relatives make thousands of different specialised metabolites – a true treasure trove for the potential discovery of new antibiotics.
EARTHY PERFUMERY COMPOUNDS
Petrichor is the term coined for the unique, earthy smell associated with rain. It is caused by the water from the rain, along with certain compounds like ozone, geosmin, and plant oils. These earthy compounds can be floral, root, leafy, muddy and green.
|Earthy.Compounds||Strong Rooty, Muddy, Bay, Floral Fancy.|
Our Perfumes using earthy notes may be floral, fruity or citrus in nature. These strong earthy notes are very good middle notes and are used for stability for any compound, the suitability chart is as follows:
Our fragrance are free from alcohol, non-inflammable, non-hazardous, non-toxic and for industrial use only.
|Creams and Lotions||9|
9 = Very Good Performance
8 = Good Performance
7 = Reasonable performance
6 = Fair performance
5 = Mediocre performance
4 = Slight stability problems
3 = Discoloration Problems
2 = Stability problems
1 = Major problems
0 = XX Not recommended for use
Please Note: Due to the fact that our fragrances are very concentrated, we suggest that you test our fragrances in finished products before you make any conclusions about our fragrances. Since our fragrances are so strong, we suggest only using 0.5 to max 4% in any finished product. Our testing notes should never take the place of your own personal testing. Always test fragrance in finished (product) applications.
EARTHY SCIENCE OF PERFORMANCE
Different compounds are involved to varying degrees in the smell of rain, depending on whether we’re talking about the post-rain or the pre-rain smell. The major origin of these compounds are bacteria in the ground and soil, oils released by plants during periods of dry weather, and electrical charge in the vicinity of thunderstorms. These oils collect in the soil and in rocks; rain then causes a range of smaller, volatile compounds within them to be released into the air. Their combination with geosmin in the air causes ‘petrichor’. The closed-loop stripping analysis (CLSA) method of Grob, in combination with gas chromatography/mass spectrometry (GC/MS), has been used in the determination of earthy-musty-smelling compounds. This technique has been modified to include the CLSA of sediments and laboratory-grown microbiological cultures in order to investigate the sources of the odorous compounds.
