UV Akayunguruzo Octyl Methoxycinnamate CAS 5466-77-3 Ukwakira 4-Methoxycinnamate

Octyl mikorerexycinnamate, izwi kandi nka Ethylhexyl mitoxycinnamate (EHMC), ni urugimbu kama rukoreshwa cyane cyane nka filteri ya UV mubikoresho bitandukanye byo kwisiga no kwita kubantu. Ifite imiti ya C16H24O3 kandi ishyirwa mubikorwa bya estxyxycinnamate ester. Uru ruganda ruzwi cyane kubera ubushobozi bwo gukurura imirasire ya ultraviolet (UV), cyane cyane imirasire ya UVB, yangiza uruhu rwabantu.

Imiterere yimiti nibyiza

Muburyo bwa chimique, octyl mikorerexycinnamate ikomoka kuri acidexyxycinnamic, ikaba ikomoka kuri acide cinnamic hamwe nitsinda ryimikorere. Umuvuduko wa octyl, ukomoka kuri 2-Ethylhexanol, utanga uruvange hamwe na lipofilique, bigatuma rushobora gushonga mu mavuta hamwe n’indi miti ikomoka ku buhinzi, bityo bikongerera ubushobozi bwo kwisiga.

Octyl mikorerexycinnamate yerekana spekure yihariye ya UV, cyane cyane ikurura imirasire ya UVB iri hagati ya 280 na 320 nanometero (nm). Uru rutonde ni ingenzi cyane kubera ko imirasire ya UVB ishinzwe gutwika izuba kandi ikagira uruhare mu kwangiza uruhu, harimo gusaza imburagihe ndetse no kongera kanseri y'uruhu. Mugukuramo imirase yangiza, octyl mitoxycinnamate ifasha kurinda uruhu izo ngaruka mbi.

Imikoreshereze yo kwisiga hamwe nibicuruzwa byizuba

Mu nganda zo kwisiga, octyl mitoxycinnamate nikintu gikoreshwa cyane muburyo bwo kwirinda izuba. Bikunze guhuzwa nizindi UV muyunguruzi kugirango habeho izuba ryinshi ryizuba ritanga uburinzi bwumuriro UVA na UVB. Ihuriro ryayunguruzo rutandukanye ningirakamaro kuko buri bwoko bwa filteri ikurura intera yihariye yuburebure, bityo igatanga uburinzi bwuzuye.

Imirasire y'izuba irimo octyl mitoxycinnamate isanzwe igenewe kurwanya amazi, ikemeza ko ibicuruzwa bikomeza kuba byiza na nyuma yo guhura n’amazi cyangwa ibyuya. Ibi ni ingenzi cyane mubikorwa byo hanze na siporo, aho izuba ryizuba rishobora gukaraba, bigatuma uruhu rushobora kwangirika UV.

Ibitekerezo byumutekano no kugenzura

Umutekano wa octyl mitoxycinnamate wasuzumwe cyane n’inzego zishinzwe kugenzura nk’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA) na komite y’ubumenyi ya komisiyo y’uburayi ishinzwe umutekano w’abaguzi (SCCS). Nk’uko aya mashyirahamwe abivuga, octyl mitoxycinnamate ifatwa nk’umutekano kugira ngo ikoreshwe mu bicuruzwa byo kwisiga, harimo n’izuba, iyo bikoreshejwe mu gihe cyagenwe.

Nyamara, kimwe na chimique UV yose yungurura, octyl mitoxycinnamate ifite amahirwe yingaruka mbi iyo ikoreshejwe nabi cyangwa niba kwibanda kurenza urwego rwasabwe. Ubushakashatsi bumwe bwerekanye ko bushobora gutera uburakari cyangwa allergique ku bantu bumva. Niyo mpamvu, ni ngombwa ko abayikora bubahiriza umurongo ngenderwaho utangwa ninzego zishinzwe kugenzura no kubakoresha gusoma neza no gukurikiza amabwiriza yo gukoresha.

Ingaruka ku bidukikije

Ingaruka ku bidukikije ya octyl mitoxycinnamate ni ingingo yubushakashatsi bukomeje. Ubushakashatsi bumwe bwerekanye ko bushobora kugira ingaruka ziterwa n’ubumara ku binyabuzima byo mu mazi, cyane cyane mu nzego zo hejuru. Ibi byateje impungenge kubyerekeranye nubushobozi bwayo bwo kwirundanyiriza mubidukikije byo mu nyanja, cyane cyane mu turere two ku nkombe aho usanga hakoreshwa cyane ibicuruzwa bituruka ku zuba.

Nkigisubizo, hari kwiyongera kwiterambere mugutezimbere ibidukikije byangiza ibidukikije. Mugihe octyl mikorerexycinnamate ikomeje gukoreshwa cyane kandi ikora neza ya filteri ya UV, ingaruka zayo kubidukikije zatumye hashakishwa uburyo burambye burambye, nkibibuza umubiri (urugero, okiside ya zinc na titanium dioxyde) hamwe nayungurura imiti mabi itangiza ubuzima bwamazi.
