Cov kev siv ntawm Octyl 4-methoxycinnamate yog dab tsi?
Daim ntawv thov tseem ceeb ntawm octyl methoxycinnamate (CAS 5466-77-3) yog hais txog kev tiv thaiv ultraviolet, npog cov teb xws li tshuaj pleev ib ce thiab cov ntaub ntawv kev lag luam, raws li nram no:
Kev siv tseem ceeb: Kev lag luam pleev ib ce (cov xwm txheej tseem ceeb-octyl methoxycinnamate rau daim tawv nqaij)
Cov khoom xyaw tseem ceeb ntawm cov tshuaj pleev thaiv hnub siv tau nrog ntau yam khoom siv tiv thaiv hnub xws li tshuaj pleev, tshuaj pleev, tshuaj tsuag thiab gel. Octyl 4-methoxycinnamate tsom mus rau kev tiv thaiv UVB kom tiv thaiv daim tawv nqaij kom tsis txhob liab, kub hnyiab thiab tawv nqaij dub.
Ntxiv cov khoom siv tu tawv nqaij txhua hnub xws li toner, essence thiab lotion tsis yog tsuas yog muaj cov haujlwm ntawm kev tiv thaiv hnub thiab tiv thaiv kev laus xwb, tab sis kuj txo qhov photodamage ntawm ultraviolet rays rau daim tawv nqaij.
Cov khoom siv tshwj xeeb rau kev saib xyuas tawv nqaij, isooctyl-4-methoxycinnamate siv rau hauv cov khoom saib xyuas tawv nqaij rau kev kho mob pabcuam ntawm cov kab mob photosensitive dermatitis, kom txo qhov rhiab heev ntawm daim tawv nqaij los ntawm cov duab ultraviolet.
Kev siv thib ob: Kev lag luam thiab lwm yam teb
Cov neeg sawv cev tiv thaiv kev laus thiab cov khoom nqus ultraviolet rau cov yas thiab cov khoom siv resin, ncua kev laus, daj thiab embrittlement ntawm cov khoom yas los ntawm ultraviolet hluav taws xob.
Cov tshuaj ntxiv rau cov kua mem thiab cov tshuaj pleev xim ua rau cov khoom tiv taus huab cua zoo dua, tiv thaiv kom tsis txhob lwj thiab puas tsuaj tom qab raug tshav ntuj, thiab ua kom lawv lub neej siv ntev dua.
Thaum siv ua ke nrog lwm cov tshuaj pleev thaiv hnub, octyl methoxycinnamate siv tau raws li qhov xav tau kev tiv thaiv sib txawv thiab nthuav dav ntau yam kev tiv thaiv ultraviolet ntawm cov khoom (xws li thaum ua ke nrog UVA absorbers).
Octyl 4-methoxycinnamate muaj kev ruaj khov zoo heev thiab tsis yooj yim lwj thaum khaws cia rau hauv chav sov thiab deb ntawm lub teeb. Nws cov qauv tseem ruaj khov hauv pH ntau (5.5-7.5) ntawm cov tshuaj pleev ib ce. Lub octyl methoxycinnamate muaj kev nyab xeeb tswj tau. Octyl-methoxycinnamate (OMC) tau txais kev pom zoo los ntawm cov tub ceev xwm hauv ntau lub tebchaws rau kev siv hauv cov tshuaj pleev ib ce. Thaum siv raws li cov cai, nws yog mos rau ntawm daim tawv nqaij ntawm cov neeg feem coob.
