Menthol is also used to prepare menthyl esters to emphasize floral notes (especially rose) (L1263). Used to treat occasional minor irritation、pain、sore mouth、and sore throat as well as cough associated with a cold or inhaled irritants.、Use Classification: Fragrance Ingredients、Fragrance Ingredients、Flavouring Agent -> FLAVOURING_AGENT -> JECFA Functional Classes、Flavoring Agents -> JECFA Flavorings Index、Cosmetics -> Soothing、Denaturant、Masking、Refreshing、Industry Uses: Odor agents、Odor agents、Fragrance、Consumer Uses: Fragrance、Household Products: Cosmetics product ingredient: Menthol (dl-menthol、l-menthol、d-menthol)、Menthol is a fragrance allergen. Fragrance allergens are hazardous only to individuals who suffer from fragrance allergies. The Cosmetic Fragrance and Flavor Ingredient Right to Know Act of 2020 requires fragrance allergens included in Annex III of the EU Cosmetics Regulation No. 1223、2009 be reported to the California Department of Public Health. Fragrance allergens are only required to be reported if present in a rinse-off cosmetic product at a concentration at or above 0.01 percent (100 parts per million) or in a leave-on cosmetic product at a concentration at or above 0.001 percent (10 parts per million).、For more information、you can visit the fragrance allergens webpage on the California Safe Cosmetics Program website:、https:、www.cdph.ca.gov、Programs、CCDPHP、DEODC、OHB、CSCP、Pages、FragranceAllergens.aspx、Product count: 1285、Information on 149 consumer products that contain Menthol in the following categories is provided:、• Commercial、Institutional、• Inside the Home、• Personal Care、• Pet Care、Information on 35 consumer products that contain Menthol (Racementhol) in the following categories is provided:、Methods of Manufacturing: (-)-Menthol from (+-)-Menthol. (+-)-Menthol can be prepared via several routes and subsequently resolved into the optical isomers: a. Racemic menthol can be synthesized by hydrogenation of thymol. This yields a mixture containing the four stereoisomeric menthols in various proportions. (+-)-Menthol is separated from the other isomers by distillation. The remaining isomeric menthols、neomenthol、isomenthol、and a trace of neoisomenthol、can be epimerized、under the conditions used for the thymol hydrogenation、to give ca. 6:3:1 equilibrium mixture of (+-)-menthol、(+-)-neomenthol、and (+-)-isomenthol、respectively. (+-)-Menthol can、again、be distilled from the equilibrium mixture. b. (+-)-Menthol can be resolved into its optical antipodes by several routes. A large-scale industrial process utilizes selective crystallization of either (+)- or (-)-menthyl benzoate by seeding saturated solutions or supercooled melts of (+-)-menthyl benzoates with crystals of (+)- or (-)-menthyl benzoate. Pure (+)- or (-)-menthol is obtained following hydrolysis of the esters. The undesired (+)-menthol can be reconverted into the racemate. Biochemical resolution methods have also been developed.、(-)-Menthol can also be prepared from (-)-piperitone、the main component of Eucalyptus dives Typus oils. Hydrogenation in the presence of Raney nickel yields a mixture of menthols、from which (-)-menthol can be separated by crystallization and saponification of its chloroacetate.、(-)-Menthol from (+)-Citronellal. This process uses the readily occurring cyclization of citronellal to isopulegol. (+)-Citronellal can be isolated with an optical purity of about 80% from citronella oil. Alternatively、it can be synthesized with a purity of 98% from dialkylgeranylamine (obtained from myrcene and a dialkylamine) by enantioselective isomerization to (+)-citronellaldialkylenamine followed by hydrolytic cleavage to (+)-citronellal. Isomerization is effected in the presence of a chiral rhodium-phosphine complex as a catalyst. (+)-Citronellal is cyclized in the presence of acidic catalysts (e.g.、silica gel) to give a mixture of optically active isopulegol isomers containing about 20% of the corresponding racemates. (-)-Isopulegol can be isolated from this mixture and hydrogenated to (-)-menthol. The remaining isopulegol stereoisomers can be partly reconverted into (+)-citronellal by pyrolytic cleavage and reused in the cyclization procedure. |
