UV Filter Octyl Methoxycinnamate CAS 5466-77-3 Octyl 4-Methoxycinnamate

Octyl methoxycinnamate, e tsejoang hape e le ethylhexyl methoxycinnamate (EHMC), ke motsoako oa lintho tse phelang tse sebelisoang haholo e le sefe ea UV lihlahisoa tse fapaneng tsa litlolo le tsa tlhokomelo ea motho. E na le foromo ea lik'hemik'hale C16H24O3 'me e khetholloa e le methoxycinnamate ester. Motsoako ona o tsebahala haholo ka matla a oona a ho monya mahlaseli a ultraviolet (UV), haholo-holo mahlaseli a UVB, a kotsi letlalong la motho.

Sebopeho sa Lik'hemik'hale le Thepa

Ka lik'hemik'hale, octyl methoxycinnamate e nkiloe ho methoxycinnamic acid, e leng motsoako oa cinnamic acid e nang le sehlopha sa methoxy se kopantsoeng. Motsoako oa octyl, o tsoang ho 2-ethylhexanol, o fana ka motsoako o nang le lipophilic properties, o etsa hore o qhibilihe ka har'a oli le lihlahisoa tse ling tsa lintho tse phelang, kahoo o matlafatsa ho lumellana ha oona le litlolo tsa litlolo.

Octyl methoxycinnamate e bonts'a khanya e khethehileng ea UV, haholo-holo e monyang mahlaseli a UVB ho tloha ho 280 ho isa ho 320 nanometers (nm). Letoto lena le bohlokoa haholo hobane mahlaseli a UVB a ikarabella bakeng sa ho chesoa ke letsatsi 'me a kenya letsoho ho senyeheng ha letlalo, ho kopanyelletsa le ho tsofala pele ho nako le kotsi e eketsehileng ea ho tšoaroa ke kankere ea letlalo. Ka ho monya mahlaseli ana a kotsi, octyl methoxycinnamate e thusa ho sireletsa letlalo liphellong tsena tse mpe.

E sebelisoa ho Litlolo le Lihlahisoa tsa Letsatsi

Indastering ea litlolo, octyl methoxycinnamate ke motsoako o sebelisoang haholo ho etsa litlolo tse sireletsang letsatsi. Hangata e kopantsoe le lihloela tse ling tsa UV ho etsa litlolo tse sireletsang letlalo letsatsing tse fanang ka tšireletso khahlanong le mahlaseli a UVA le UVB. Motsoako oa li-filters tse fapaneng o bohlokoa hobane mofuta o mong le o mong oa sefe o monya mefuta e fapaneng ea maqhubu, kahoo o fana ka tšireletso e felletseng.

Li-sunscreens tse nang le octyl methoxycinnamate hangata li etselitsoe ho thibela metsi, ho netefatsa hore sehlahisoa se lula se sebetsa le ka mor'a ho pepesehela metsi kapa mofufutso. Sena se bohlokoa haholo bakeng sa mesebetsi ea kantle le lipapali, moo litlolo tsa setso tsa letsatsi li ka hlatsuoang, tse sieang letlalo le le kotsing ea tšenyo ea UV.

Litlhokomelo tsa Polokeho le Taolo

Tšireletseho ea octyl methoxycinnamate e hlahlobiloe haholo ke mekhatlo e laolang e kang US Food and Drug Administration (FDA) le European Commission's Scientific Committee on Consumer Safety (SCCS). Ho latela mekhatlo ena, octyl methoxycinnamate e nkuoa e bolokehile hore e ka sebelisoa lihlahisoa tsa litlolo, ho kenyeletsoa le li-sunscreens, ha li sebelisoa ka har'a meeli e boletsoeng.

Leha ho le joalo, joalo ka li-filters tsohle tsa lik'hemik'hale tsa UV, octyl methoxycinnamate e na le monyetla oa ho ba le litlamorao tse mpe haeba e sebelisoa hampe kapa haeba khatello e feta maemo a khothaletsoang. Liphuputso tse ling li bontšitse hore e ka baka ho teneha kapa ho hanana le batho ba bang. Ka hona, ho bohlokoa hore bahlahisi ba khomarele litataiso tse fanoeng ke mekhatlo ea taolo le hore bareki ba bale ka hloko le ho latela litaelo tsa tšebeliso.

Tšusumetso ea Tikoloho

Tšusumetso ea tikoloho ea octyl methoxycinnamate ke sehlooho sa lipatlisiso tse tsoelang pele. Liphuputso tse ling li bontšitse hore e ka ba le phello e chefo e itšetlehileng ka mahlonoko ho lintho tse phelang metsing, haholo-holo maemong a holimo. Sena se entse hore ho be le matšoenyeho mabapi le monyetla oa ho bokellana libakeng tsa leoatle, haholo-holo libakeng tse lebōpong la leoatle moo ho nang le tšebeliso e kholo ea lihlahisoa tse sireletsang letsatsi.

Ka lebaka leo, ho na le thahasello e ntseng e eketseha ho nts'etsopele ea mekhoa e meng e sireletsang letlalo letsatsing. Leha octyl methoxycinnamate e ntse e le sefahla sa UV se sebelisoang haholo le se sebetsang hantle, phello ea eona ea tikoloho e khothalelitse ho batla likhetho tse tšoarellang, joalo ka li-blockers tsa 'mele (mohlala, zinc oxide le titanium dioxide) le li-filters tse ncha tsa lik'hemik'hale tse seng kotsi haholo ho bophelo ba metsing.
