Spearmint oil, derived from Mentha viridis, is a cooling, aromatic stimulant with cleansing and decongesting properties. It is also astringent, adding fragrance while helping mask odors. Its fragrance and therapeutic activity are similar to peppermint but fresher and less harsh. Used in Flavor Industry: Spearmint oil is used as a flavoring agent for toothpaste and chewing gum due to its fresh, minty aroma and cooling properties. Used in Oral Care Industry: Spearmint oil is used as an ingredient in oral care products for its cleansing and decongesting properties, promoting a fresh and healthy oral environment. Used in Pharmaceutical Industry: Spearmint oil is used in pharmaceutical preparations for its therapeutic activity, particularly for acne and oily skin, due to its astringent and cleansing properties. Used in Fragrance Industry: Spearmint oil is used as a fragrance component in various products, such as perfumes and scented candles, for its fresh, caraway, and minty odor. Physical and Chemical Properties: Spearmint oil is a colorless, pale-yellow to greenish-yellow liquid that can be rectified by distillation. It is obtained by steam distillation of the flowering herbs of Mentha spicata L. ssp. spicata and Mentha x gracilis Sole. The oil has a fresh, caraway, minty odor with a specific gravity (d2020) of 0.921–0.938, refractive index (n20D) of 1.484–1.491, and a carbonyl number of ≥224, corresponding to a carvone content of 60%. It is soluble in 70% ethanol at 20°C, with 1 volume of oil soluble in ≤3 volumes of ethanol. Production and Main Producers: The United States, particularly the state of Washington, is the main producer of spearmint oil, with a total annual North American production of around 1200 tons. Smaller amounts are also produced in some Midwest states and Canada. Other cultivation areas for spearmint oils exist in China and India, with a combined production of around 800 tons. Oils with a higher carvone content are obtained by redistillation.
The oil contains α-pinene, α-phellandrene, l-limonene, octyl alcohol, dipentene cineol (in some varieties only), dihydrocarveol and carvone. Esters of acetic butyric and caproic acids are also reported present in the oil.
Safety Profile

Check Digit Verification of cas no
The CAS Registry Mumber 8008-79-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 8 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 8008-79: (6*8)+(5*0)+(4*0)+(3*8)+(2*7)+(1*9)=95 95 % 10 = 5 So 8008-79-5 is a valid CAS Registry Number.
