Ethyl cinnamate

Ethyl cinnamate is not common in daily life, but with the development of various technologies in recent years, its application has become more and more extensive, so it is particularly important for people to have a certain understanding of it. It is also known as ethyl phenylacrylate, ethyl cinnamate, etc. It is a colorless to light yellow liquid with a faint aroma. It is insoluble in water but soluble in ethanol, ether and most non-volatile oils.

1. Basic Information

Chinese name: Ethyl cinnamate

Chinese alias: 3-phenyl-2-ethyl acrylate; phenyl acrylate ethyl; cinnamic acid ethyl ester; cinnamic acid ethyl ester; cinnamic acid ethyl ester; β-phenyl acrylate ethyl ester; phenyl acrylate ethyl ester; 3-phenyl acrylate ethyl

Physical and chemical properties:

Appearance: colorless to light yellow liquid.

Relative density (d435) 1.049

Melting point 6-8 °C

Boiling point 270-272 °C

Flash point>110℃

Refractive index (nD20) 1.558

fragrance

Light, lingering aromas of cinnamon and strawberry with a sweet honey scent.

3. Dissolution

Miscible in ethanol, ether and most non-volatile oils, almost insoluble in glycerol and water, slightly soluble in propylene glycol.

4. Chemical properties

It has the aroma and background of sweet orange and grape, and the fragrance is long-lasting. It has the properties of a general ester and undergoes hydrolysis under the action of caustic alkali. Because it contains double bonds, it is easy to polymerize under the action of light and heat. When stored in the dark for a long time, it emits rose red fluorescence, turns green under transmitted light, and produces white insoluble powder.

5. Application

Ethyl cinnamate can be added to cigarette tobacco as a flavor enhancer and flavor compensator. The monomer boiling point is above 270°C. The tobacco retention rate after flavoring, the mainstream particle phase transfer rate after smoking and the filter retention rate can be significantly improved and are relatively stable. It is an excellent cigarette flavoring agent.

Since the country clearly put forward the development requirements of Chinese cigarettes with "high aroma, low tar and low harm", promoting the work of reducing the harm and tar of cigarettes and cultivating low-tar cigarette brands have become the focus of attention of the tobacco industry. As consumers pay more attention to smoking and health issues, high-quality cigarettes with "high aroma, low tar and low harm" are also in line with the future development trend of the cigarette market and meet the actual needs of consumer demand. However, what worries the nearly 500 million smokers in the country is that once the tar content is reduced, the flavor of the cigarette will inevitably decrease. If the demand of many smokers for the flavor of cigarettes cannot be met, the national cigarette market will face a huge impact. How to reduce the tar content while effectively compensating for the flavor of cigarettes has become a primary issue that domestic tobacco companies urgently need to solve. Current studies have found that adding ethyl cinnamate to cigarette tobacco can effectively improve the flavor of cigarettes. The monomer boiling point of ethyl cinnamate is above 270°C. After adding it into tobacco, it can effectively improve the aroma retention rate, the mainstream particle phase transfer rate after smoking and the filter retention rate, and make them relatively stable. It can also produce a harmless dependence effect on the human body. It is a very perfect cigarette flavor enhancer.

At present, the United States, Britain, Germany and other European and American countries have adopted cinnamon esters such as ethyl cinnamate in tobacco additive raw materials to enhance flavor and reduce harm. Wuhan Cigarette Factory, Sichuan Panzhihua Tobacco Company and Henan China Tobacco Industrial Co., Ltd. have followed the international trend and added ethyl cinnamate as a cigarette flavor enhancer into the production of new cigarettes. This not only reduces the harm of cigarettes to the majority of smokers, but also does not reduce the original aroma of cigarettes. The market response and social and economic benefits are very good. Ethyl cinnamate has effectively promoted the sustainable and healthy development of the cigarette industry. The new low-tar, high-aroma cigarettes containing ethyl cinnamate will surely become the loyal choice of 500 million smokers in the future!

This product exists in natural styrax and has a fruity aroma. It works best when used with clary styrax and natural fruit essential oils. It is even better when used in scented powders, perfumes, and essences. It is widely used in rose, citrus, narcissus, ambergris, amber, chypre and other flavors. It can also be used as a soap fragrance. In soap and powder flavors, it can coordinate other cream fragrances and have a fixative effect.

GB 2760-96 stipulates that it is a food flavoring temporarily allowed for use. It can be used as a edible spice, and can be used to mix daily flavors, edible flavors, etc. It can be used to mix flavors such as almond, vanilla, cinnamon, honey, berries, mixed sweet drinks, balm, spicy, grape and cherry. It can also be used in edible bayberry essence, which has a fresh, sweet and oriental scent. In addition, due to its high and stable boiling point, it is also suitable for use in baked foods.

Honey made from ethyl cinnamate has the miraculous effect of skin care, beauty and immunity enhancement. It can also inhibit the formation of black tyrosinase and block certain ultraviolet rays. It is one of the essential ingredients in high-grade sunscreen.

The anticancer drugs paclitaxel or docetaxel, which are synthesized using ethyl cinnamate as raw material through related chemical reactions, have significant therapeutic effects on the treatment of ovarian cancer and breast cancer.
