Isihluzo se-UV Octyl Methoxycinnamate CAS 5466-77-3 Octyl 4-Methoxycinnamate

I-Octyl methoxycinnamate, ekwabizwa ngokuba yi-ethylhexyl methoxycinnamate (EHMC), yikhompawundi ephilayo esetyenziswa ikakhulu njengesihluzo se-UV kwiimveliso ezahlukeneyo zokuthambisa kunye nezokhathalelo lomntu. Inefomula yeekhemikhali C16H24O3 kwaye ihlelwa njenge-methoxycinnamate ester. Le khompawundi yamkelwa ngokubanzi ngokukwazi kwayo ukufunxa imitha ye-ultraviolet (UV), ngokukodwa imitha ye-UVB, eyingozi eluswini lomntu.

Ulwakhiwo lweMichiza kunye neePropati

Ngokwekhemikhali, i-octyl methoxycinnamate ithathwe kwi-methoxycinnamic acid, ephuma kwi-cinnamic acid eneqela le-methoxy eliqhotyoshelweyo. I-octyl moiety, ephuma kwi-2-ethylhexanol, inika i-compound eneempawu ze-lipophilic, eyenza i-soluble kwi-oyile kunye nezinye i-solvents eziphilayo, ngaloo ndlela iphucula ukuhambelana kwayo kunye ne-cosmetic formulations.

I-Octyl methoxycinnamate ibonisa i-UV ethile yokufunxa spectrum, ifunxa imitha ye-UVB kuluhlu lwama-280 ukuya kwi-320 nanometers (nm). Olu luhlu lubaluleke kakhulu kuba imitha ye-UVB inoxanduva lokutshiswa lilanga kwaye inegalelo kumonakalo wolusu, kubandakanya ukuguga kwangaphambi kwexesha kunye nomngcipheko owongeziweyo womhlaza wolusu. Ngokufunxa le mitha iyingozi, i-octyl methoxycinnamate inceda ukukhusela ulusu kule miphumo mibi.

Ukusetyenziswa kwi-Cosmetics kunye ne-Sunscreen Products

Kushishino lwezithambiso, i-octyl methoxycinnamate sisithako esisetyenziswa kakhulu kwimixube yesunscreen. Ihlala idityaniswa nezinye izihluzi ze-UV ukwenza izikhuselo zelanga ezibanzi ezibonelela ngokhuseleko kwimitha ye-UVA kunye ne-UVB. Indibaniselwano yezihluzi ezahlukeneyo zibalulekile kuba udidi ngalunye lwesihluzo lufunxa uluhlu oluthile lwamaza obude, ngaloo ndlela lubonelela ngokhuseleko olubanzi.

Izikrini zelanga eziqukethe i-octyl methoxycinnamate ngokuqhelekileyo ziyilelwe ukuba zinganyangeki emanzini, ziqinisekisa ukuba imveliso ihlala isebenza nasemva kokuvezwa kwamanzi okanye ukubila. Oku kubaluleke kakhulu kwimisebenzi yangaphandle kunye nemidlalo, apho izithambiso zelanga zemveli zinokuhlanjwa, zishiya ulusu lusengozini yomonakalo we-UV.

Iingqwalasela zoKhuseleko noLawulo

Ukhuseleko lwe-octyl methoxycinnamate luye lwavavanywa ngokubanzi ngamaqumrhu alawulayo afana ne-US Food and Drug Administration (FDA) kunye neKomiti yeNzululwazi yeKhomishini yaseYurophu kuKhuseleko loMthengi (SCCS). Ngokwale mibutho, i-octyl methoxycinnamate ithathwa njengekhuselekile ukusetyenziswa kwiimveliso zokuthambisa, kubandakanywa ne-sunscreens, xa isetyenziswe ngaphakathi kwemida yoxininiso echaziweyo.

Nangona kunjalo, njengazo zonke izihluzi zeekhemikhali ze-UV, i-octyl methoxycinnamate inokuba nemiphumo emibi ukuba isetyenziswe kakubi okanye ukuba ugxininiso ludlula amanqanaba acetyiswayo. Olunye uphononongo lucebise ukuba lunokubangela ukucaphuka okanye ukuchasana nabantu ababuthathaka. Ke ngoko, kubalulekile ukuba abavelisi bathobele izikhokelo ezinikezelwe ngamaqumrhu alawulayo kunye nokuba abathengi bafunde ngononophelo kwaye balandele imiyalelo yokusetyenziswa.

Impembelelo yokusingqongileyo

Impembelelo yokusingqongileyo ye-octyl methoxycinnamate sisihloko sophando oluqhubekayo. Olunye uphononongo lubonise ukuba lunokuba nempembelelo eyityhefu exhomekeke kugxininiso kwizinto eziphilayo zasemanzini, ngakumbi kumanqanaba aphezulu. Oku kukhokelele kwinkxalabo malunga nokuba kungenzeka ukuba iqokelele kwiindawo zaselwandle, ngakumbi kwiindawo eziselunxwemeni apho kukho ukusetyenziswa okubalulekileyo kweemveliso zokukhusela ilanga.

Ngenxa yoko, kukho umdla okhulayo ekuphuhliseni ezinye iindlela zokuzikhusela kwilanga ezilungele ukusingqongileyo. Ngelixa i-octyl methoxycinnamate ihlala isisihluzo se-UV esisetyenziswa ngokubanzi nesisebenzayo, impembelelo yayo yokusingqongileyo ibangele ukuba kukhangelwe iinketho ezizinzileyo, ezifana nezithinteli zomzimba (umzekelo, i-zinc oxide kunye ne-titanium dioxide) kunye nezihluzo zemichiza ezinoveli ezingenabungozi kangako kubomi basemanzini.
