nkhani

Octyl 4-methoxycinnamate(OMC) ndi mankhwala oteteza ku dzuwa omwe amagwiritsidwa ntchito kwambiri, oletsa kukalamba komanso oletsa ultraviolet, okhala ndi nambala ya CAS ya 5466-77-3. Fomula ya molekyulu ndi C18H26O3 ndipo kulemera kwa molekyulu ndi 290.4. Ma Chinese ofanana ndi 4-Methoxycinnamic Acid octyl Ester, 4-methoxycinnamic acid isooctyl ester, ndi zina zotero. Ma Chinese ofanana ndi Isooctyl-4-methoxycinnamate, 2-ethylhexyl-p-methoxycinnamate, Octyl-methoxycinnamate (OMC), ndi zina zotero.

Molekyulu ya Octyl 4-methoxycinnamate ili ndi chomangira chachikulu cha π cholumikizidwa. Kapangidwe kameneka kamatsimikizira kuti chinthuchi chili ndi mphamvu yoyamwa kuwala kwa ultraviolet, komwe kumatha kuyamwa kuwala kwa ultraviolet mkati mwa kutalika kwa mafunde a 280-310nm, ndi kuyamwa kwakukulu pa 311nm, zomwe zimathandiza kupewa kuwonongeka kwa UVB pakhungu.

Ubwino waukulu wa Octyl 4-methoxycinnamate

1. Octyl-methoxycinnamate (OMC)Mafuta oteteza ku dzuwa amateteza kwambiri khungu ndipo makamaka amateteza UVB. OMC ili ndi mphamvu yoyamwa pafupifupi 311nm ndipo imatha kukana bwino bandeji yomwe imayambitsa kufiira kwa khungu komanso kutentha kwa dzuwa.

2. Octyl 4-methoxycinnamate imagwirizana bwino kwambiri ndipo imatha kuwonjezeredwa ndi zodzoladzola zachilengedwe monga zinc oxide ndi titanium dioxide, kapena zodzoladzola zachilengedwe monga oxalilin, popanda kusokoneza kukhazikika kwa mankhwalawa.

3. Isooctyl-4-methoxycinnamate imakhala yothandiza pakhungu, imakhala yamadzimadzi ndipo imasungunuka mosavuta mu zosungunulira zachilengedwe. Ikawonjezeredwa ku sunscreen, octyl methoxycinnamate sidzayambitsa mavuto olemera kapena kuyera, ndipo ndi yoyenera kugwiritsa ntchito njira zotsitsimula.

4. Ndi mtengo wokwera, ukadaulo wopanga zinthu zakale komanso mitengo yotsika ya zinthu zopangira, octyl 4-methoxycinnamate ndi chisankho chodziwika bwino cha zinthu zoteteza ku dzuwa zomwe zimakhala zotsika mtengo kuyambira pakati mpaka zapamwamba.

5. Octyl 4-methoxycinnamate ili ndi kukhazikika bwino ndipo siiwonongeka mosavuta pansi pa kusungidwa bwino ndi kugwiritsidwa ntchito moyenera, zomwe zimapangitsa kuti chitetezo cha dzuwa chikhale cholimba.

Kodi Octyl 4-methoxycinnamate imagwiritsa ntchito chiyani?

Kugwiritsa ntchito kwakukulu kwa octyl methoxycinnamate (CAS 5466-77-3) kumagwirizana ndi chitetezo cha ultraviolet, chomwe chimaphimba minda monga zodzoladzola ndi zipangizo zamafakitale, motere:

Ntchito zazikulu: Munda wa zodzoladzola (zochitika zazikulu-octyl methoxycinnamate ya khungu)

Chosakaniza chachikulu cha mafuta oteteza ku dzuwa omwe amapezeka mu mafuta oteteza ku dzuwa chimagwirizana ndi zinthu zosiyanasiyana zoteteza ku dzuwa monga lotion, kirimu, spray ndi gel. Octyl 4-methoxycinnamate imayang'ana kwambiri pa chitetezo cha UVB kuti khungu lisapse, lisamapse ndi dzuwa.

Kuwonjezera zinthu zosamalira khungu tsiku ndi tsiku monga toner, essence ndi lotion sikuti kumangoteteza ku dzuwa komanso kuletsa ukalamba, komanso kumachepetsa kuwonongeka kwa kuwala kwa ultraviolet pakhungu.

Zinthu zapadera zosamalira khungu, isooctyl-4-methoxycinnamate, zomwe zimagwiritsidwa ntchito muzinthu zosamalira khungu pochiza dermatitis yokhudzana ndi kuwala kwa dzuwa, kuti zichepetse kukhudzidwa kwa khungu komwe kumachitika chifukwa cha kuwala kwa ultraviolet.

Ntchito zina: Makampani ndi madera ena

Zinthu zoletsa kukalamba ndi zoyamwitsa za ultraviolet za pulasitiki ndi utomoni, zomwe zimachedwetsa kukalamba, chikasu ndi kuuma kwa zinthu zapulasitiki chifukwa cha kuwala kwa ultraviolet.

Zowonjezera za inki ndi zokutira zimathandiza kuti zinthu zisawonongeke ndi nyengo, zimateteza kuuma ndi kuwonongeka pambuyo pa dzuwa, komanso zimawonjezera nthawi yogwira ntchito.

Ikagwiritsidwa ntchito limodzi ndi zodzoladzola zina zoteteza ku dzuwa, kugwiritsa ntchito kwa octyl methoxycinnamate kumatha kukwaniritsa zosowa zosiyanasiyana zotetezera ndikukulitsa chitetezo cha ultraviolet cha mankhwalawa (monga kuphatikiza ndi zonyowa za UVA).

Octyl 4-methoxycinnamate Ili ndi kukhazikika bwino ndipo siiwonongeka ikasungidwa kutentha kwa chipinda komanso kutali ndi kuwala. Kapangidwe kake kamakhala kokhazikika mkati mwa pH (5.5-7.5) ya zodzoladzola zodziwika bwino. Chotetezeka cha octyl methoxycinnamate chimawongoleredwa. Octyl-methoxycinnamate (OMC) chavomerezedwa ndi akuluakulu olamulira m'maiko ambiri kuti chigwiritsidwe ntchito mu zodzoladzola. Ikagwiritsidwa ntchito motsatira malamulo, imakhala yofewa pakhungu la anthu ambiri.
