What is Citronellal Sigma?

Citronellal Sigma is the main component of citronella oil, which naturally exists in essential oils such as lemon eucalyptus oil and citronella oil, with the content reaching 75% to 80% and 30% to 40%, respectively. This product is insoluble in water and glycerin, soluble in ethanol and oil, slightly soluble in propylene glycol. A strong, fresh, green citrus-like, slightly woody aroma. Unstable on exposure to air, sunlight and contact with alkalis. Citronellal can form binary azeotropes with nitrobenzene, m-cresol, ethylene glycol, benzyl alcohol, acetophenone, etc. Partially decomposed into isopulegol at 350 ℃, and stored in the air not only to obtain isopulegol, but also partially oxidized to (+)-citronellic acid, and formed peroxide, which can be inhibited by adding hydroquinone, It is oxidized with silver oxide in ammonia water to obtain citronellic acid, and catalyzed by platinum black in 75% ethanol to obtain 2,6-dimethyloctanal. At room temperature, it can be catalyzed by nickel to obtain (+)-citronellol or (+) – Dihydrocitronellol; Grignard reaction can also occur.

Citronellal Sigma can be obtained from the oxidation or catalytic dehydrogenation of citronellol, and can also be obtained from the catalytic hydrogenation of citral. Citronellal isolated from natural essential oils is optically active due to the presence of an asymmetric carbon atom in the molecule of citronellal. However, citronellal obtained from the hydrogenation of citral is a racemate and has no optical activity.

D-citronellal Sigma mainly exists in Java citronella oil (containing 30% to 40%), and L-citronellal mainly exists in lemon eucalyptus oil (containing 65% to 80%). There are two production methods: one is to vacuum distill crude aldehyde from essential oil, and then add and refine it with sodium bisulfite. Another method is the oxidation of citronellol. Due to the strong aroma of citronellal and its unstable chemical properties, it is only used in low-grade lilac, lily of the valley and other cosmetics and mosquito coils. Citronellal is mainly used in soap and cosmetic essence formulations, and the dosage is within 10%. IFRA has no restrictions.

At present, the number of Citronellal Sigma that is directly used as a fragrance in China is not much, and a large amount of Citronellal Sigma is used to synthesize hydroxycitronellal and L-menthol and other more widely used fragrances.

Citronellal Sigma Uses

  1. Citronellal Sigma is an edible seasoning specified in GB 2760-96. Generally utilized for the prep work of citrus and cherry tastes.
  2. Citronellal Sigma is mainly used as a resources for the synthesis of citronellol, hydroxycitronellal, menthol, etc. A percentage can be made use of in low-grade lemon, fragrance, magnolia, lily-of-the-valley, honey, fragrant and also other flavors, primarily for the result of highlighting the grassy greenness.
  3. Citronellal Sigma is hardly ever utilized in costs fragrances, yet is typically utilized in low-cost soap fragrances. Mostly utilized in the manufacture of vanillyl alcohol as well as hydroxycitronella vinegar. It is likewise utilized as a raw material for dihydrocorridone, and it is utilized to produce artificial menthol by isopulegol. Among them, hydroxycitronellal is just one of the most valuable fragrances.
  4. Citronellal Sigma is utilized to formulate fragrances with a solid lemon, citronella rose-like aroma.
  5. Citronellal Sigma is made use of as a fixative, planner and also conditioner, extensively utilized in aesthetic tastes; it is likewise a flavor enhancer for beverages and also foods. It can be extracted from citronella oil or prepared from isoeugenol by acetylation and oxidation.

Citronellal Sigma Production Method

The content of Citronellal Sigma in lemon eucalyptus oil is 80-90%, and the content in Java vanilla oil is 30-40%, which can be isolated from natural plants in industry. The synthesis method is mainly citronellal obtained from pinene through the stage of producing pinane, 3,7-dimethyloctadiene-1,6- and citronellol; it can also be obtained from citronellol in the presence of lead-chromium catalysts. Catalytic dehydrogenation to prepare. In addition, using nickel formate or nickel supported on alumina and adding sodium carbonate as a catalyst, hydrogenation of lemon in isopropanol, the reaction temperature is 140 ° C and the pressure is 14.7 MPa, and Citronellal Sigma can be obtained.

The secondary fractions in the fractionation of citronella oil were crude Citronellal Sigma without terpenes and geraniol. The crude product is treated with benzene and filtered by pressure. The solid is an adduct of citronellal and sodium bisulfite, and pure Citronellal Sigma is obtained by steam distillation in sodium carbonate solution. Derived from the catalytic hydrogenation of citral.

Citronellal Sigma Environmental Residency

The production and likewise use of Citronellal Sigma as a food taste active component may lead to its launch right into the ambience with various waste streams. Its use as a soap fragrance and additionally insect repellant causes its direct release into the setting. Citronellal has actually been found in various tissues and also critical oils of different plant selections. If released into the air, an approximated vapor pressure of 0.25 mm Hg at 25 ° C shows that citronellal will just exist in the ambience as a vapor. Gas-phase Citronellal Sigma deteriorates in the atmosphere by reaction with photochemically produced hydroxyl radicals; the half-life of this action in air is approximated to be 3 humans resources. Citronellal contains a chromophore that soaks up at wavelengths > 290 nm and also subsequently might be vulnerable to guide photolysis by sunshine. Citronellal is expected to have low movement if released right into dirt, based on an approximated Koc of 650. According to the approximated Henry’s Law constant of 2.6X10-4 atm-cu m/mole, volatilization from damp dirt surfaces could be a crucial fate procedure. Likewise at standard temperature as well as anxiety, the ambient vapor stress is low, nonetheless the smell can still be scented; for that reason, citronellal might evaporate from completely dry soils. Making use of the changed Sturm evaluation, 83% biodegradation was completed within 4 weeks, recommending that biodegradation is an important environmental destiny procedure in soil and additionally dirt. Also at normal temperature level and also stress, the ambient vapor anxiety is minimized, but the scent can still be scented; because of that, Citronellal Sigma might evaporate from completely dry soils. Making use of the tailored Sturm evaluation, 83% biodegradation was accomplished within 4 weeks, revealing that biodegradation is a vital ecological destiny procedure in dirt as well as dirt. Likewise at regular temperature degree as well as likewise stress, the ambient vapor stress is reduced, nevertheless the scent can still be perfumed; for that reason, Citronellal Sigma might evaporate from completely dry dusts. Making use of the customized Sturm examination, 83% biodegradation was accomplished within 4 weeks, revealing that biodegradation is a vital eco-friendly destiny process in dirt and also dirt. water. If released right into water, Citronellal Sigma is expected to adsorb right into put on hold solids and debris based upon the estimated Koc. Volatilization from water surface areas might be an important fate procedure based upon estimated Henry’s regulation constants for this compound. The approximated volatilization half-lives for the style river and also model lake are 8 humans resources and 6 days, specifically. The approximated BCF is 160, indicating a high capability for bioconcentration in marine bacteria. Hydrolysis is not anticipated to be a crucial environmental fate process, as this compound does not have useful teams to hydrolyze at ambient problems (pH 5 to 9). Work direct exposure to Citronellal Sigma may happen by means of breathing as well as additionally face direct exposure to this substance in offices where citronellal is developed or made use of. Use info suggest that the fundamental population could be revealed to citronellal through food usage, breathing, and also dermal contact with client items having citronellal.
