izindaba

I-Octyl 4-methoxycinnamate(OMC) iyisithako esivame ukusetshenziswa njenge-sunscreen, i-anti-aging agent kanye ne-ultraviolet absorber, enenombolo ye-CAS engu-5466-77-3. Ifomula yama-molecule yi-C18H26O3 kanti isisindo sama-molecule singama-290.4. Amagama afanayo esiShayina afaka i-4-Methoxycinnamic Acid octyl Ester, i-4-methoxycinnamic acid isooctyl ester, njll. Amagama afanayo esiNgisi afaka i-Isooctyl-4-methoxycinnamate, i-2-ethylhexyl-p-methoxycinnamate, i-Octyl-methoxycinnamate (OMC), njll.

I-molecule ye-Octyl 4-methoxycinnamate iqukethe isibopho esikhulu se-π esihlanganisiwe. Lesi sakhiwo esihlanganisiwe sinquma ukuthi into inamandla okumunca imisebe ye-ultraviolet, ekwazi ukumunca imisebe ye-ultraviolet ngaphakathi kobubanzi bobude be-wavelength obungu-280-310nm, kanye nokumunca okuphezulu ku-311nm, okuvimbela ngempumelelo ukulimala kwe-UVB esikhumbeni.

Inzuzo eyinhloko ye-Octyl 4-methoxycinnamate

1. I-Octyl-methoxycinnamate (i-OMC)I-sunscreen igxile kakhulu ekuvikelweni kwe-UVB. I-OMC inesilinganiso esiphakeme sokumuncwa esicishe sibe ngu-311nm futhi ingamelana ngempumelelo nebhande eliyisihluthulelo elibangela ukubomvu kwesikhumba nokushiswa yilanga.

2. I-Octyl 4-methoxycinnamate ihambisana kahle kakhulu futhi ingahlanganiswa nezithambisi zelanga ezibonakalayo njenge-zinc oxide ne-titanium dioxide, noma izithambisi zelanga zamakhemikhali njenge-oxalilin, ngaphandle kokuthinta ukuzinza komkhiqizo.

3. I-Isooctyl-4-methoxycinnamate inomuzwa ohambisana nesikhumba, isesimweni soketshezi futhi incibilika kalula ezinyibilikisini eziphilayo. Uma ifakwa ku-sunscreen, i-octyl methoxycinnamate ngeke ibangele ubunzima noma izinkinga zokwenziwa mhlophe, futhi ifanelekela amafomula avuselelayo.

4. Njengoba intengo yayo iphezulu, ubuchwepheshe bokukhiqiza obuvuthiwe kanye namanani aphakathi ezinto zokusetshenziswa, i-octyl 4-methoxycinnamate iyindlela evamile yokukhetha imikhiqizo ye-sunscreen engabizi kakhulu kusukela kwephakathi kuya kwephezulu.

5. I-Octyl 4-methoxycinnamate izinzile kakhulu futhi ayithambekeli ekuboleni ngaphansi kwezimo ezijwayelekile zokugcina nokusetshenziswa, okuqinisekisa ukuqina komphumela wokuvikela ilanga.

Yiziphi izindlela zokusebenzisa i-Octyl 4-methoxycinnamate?

Ukusetshenziswa okuyinhloko kwe-octyl methoxycinnamate (CAS 5466-77-3) kuhlobene nokuvikelwa kwe-ultraviolet, okuhlanganisa amasimu afana nezimonyo nezinto zezimboni, kanje:

Ukusetshenziswa Okuyinhloko: Insimu Yezimonyo (izimo eziyinhloko-i-octyl methoxycinnamate yesikhumba)

Isithako esiyinhloko sokuvikela ilanga se-sunscreen siyahambisana nemikhiqizo ehlukahlukene yokuvikela ilanga njenge-lotion, ukhilimu, i-spray kanye ne-gel. I-Octyl 4-methoxycinnamate igxile ekuvikeleni i-UVB ukuvimbela isikhumba ukuthi singabi bomvu, sishiswe yilanga futhi sishiswe yilanga.

Ukwengeza imikhiqizo yokunakekelwa kwesikhumba yansuku zonke njenge-toner, i-essence kanye ne-lotion akugcini nje ngokusebenza njengokuvikela ilanga kanye nokulwa nokuguga, kodwa futhi kunciphisa umonakalo we-photodamage wemisebe ye-ultraviolet esikhumbeni.

Izinto zokusetshenziswa ezikhethekile zokunakekelwa kwesikhumba, i-isooctyl-4-methoxycinnamate, esetshenziswa emikhiqizweni yokunakekelwa kwesikhumba ekwelapheni i-dermatitis ezwela ukukhanya kwelanga, ukuze kuncishiswe ukuzwela kwesikhumba okubangelwa imisebe ye-ultraviolet.

Ukusetshenziswa kwesibili: Imboni kanye neminye imikhakha

Izinto ezilwa nokuguga kanye nezinciphisi ze-ultraviolet zezinto zepulasitiki ne-resin, ezibambezela ukuguga, ukuphuzi kanye nokuqhekeka kwemikhiqizo yepulasitiki okubangelwa imisebe ye-ultraviolet.

Izithasiselo ze-inki kanye ne-coating zithuthukisa ukumelana nesimo sezulu kwemikhiqizo, zivimbele ukubuna nokuwohloka ngemva kokuchayeka elangeni, futhi zandisa isikhathi sayo sokusebenza.

Uma isetshenziswa kanye nezinye izithasiselo zokuvikela ilanga, ukusetshenziswa kwe-octyl methoxycinnamate kungahlangabezana nezidingo ezahlukene zokuvikela futhi kwandise ububanzi bokuvikelwa kwe-ultraviolet bomkhiqizo (njengalapho kuhlanganiswa nezithasiselo ze-UVA).

I-Octyl 4-methoxycinnamate inokuqina okuhle kakhulu futhi ayiboli kalula uma igcinwe ekamelweni lokushisa futhi kude nokukhanya. Isakhiwo sayo sihlala sizinzile ngaphakathi kobubanzi be-pH (5.5-7.5) bezimonyo ezivamile. I-octyl methoxycinnamate safe ingalawuleka. I-Octyl-methoxycinnamate (OMC) ivunyiwe yiziphathimandla ezilawulayo emazweni amaningi ukuze isetshenziswe ezimonyweni. Uma isetshenziswa ngokuhambisana nemithetho, ithambile esikhumbeni sabantu abaningi.
