Wafashe umwanzuro ko gukoresha izuba risanzwe ryizuba aribwo buryo bwiza kuri wewe. Birashoboka ko wumva ko ari amahitamo meza kuri wewe hamwe nibidukikije, cyangwa izuba ryizuba hamwe nibikoresho bikora bya sintetike birakaza uruhu rwawe-cyane.
Noneho urumva kubyerekeye "nanoparticles" mumirasire yizuba isanzwe, hamwe namakuru amwe n'amwe ateye ubwoba kandi avuguruzanya kubyerekeye ibice byavuzwe biguha guhagarara. Mubyukuri, guhitamo izuba risanzwe bigomba kuba biteye urujijo?
Hamwe namakuru menshi cyane, birasa nkaho ari byinshi. Noneho, reka duce urusaku hanyuma turebe kutabogamye kuri nanoparticles mu zuba ryizuba, umutekano wabo, impamvu zituma uzabishaka mumirasire yizuba nigihe utazabikora.
Nanoparticles ni iki?
Nanoparticles ni uduce duto cyane bidasanzwe byikintu runaka. Nanoparticles iri munsi ya nanometero 100. Gutanga icyerekezo runaka, nanometero ni nto inshuro 1000 kurenza ubunini bwumusatsi umwe.
Mugihe nanoparticles ishobora kuremwa mubisanzwe, nkibitonyanga bya mincule ya spray yinyanja urugero, nanoparticles nyinshi zakozwe muri laboratoire. Ku zuba ryizuba, nanoparticles ivugwa ni zinc oxyde na dioxyde ya titanium. Ibi bikoresho byacitsemo ibice byiza cyane mbere yo kongerwaho izuba ryizuba.
Nanoparticles yabonetse bwa mbere mu zuba ry’izuba mu myaka ya za 1980, ariko ntabwo yigeze ifata kugeza mu myaka ya za 90. Uyu munsi, urashobora kwibwira ko izuba ryizuba risanzwe hamwe na okiside ya zinc na / cyangwa titanium dioxyde ni nano-nini zingana keretse byerekanwe ukundi.
Ijambo "nano" na "micronize" ni kimwe. Noneho, izuba ryinshi rifite "micronized zinc oxide" cyangwa "micronized titanium dioxide" irimo nanoparticles.
Nanoparticles ntabwo iboneka gusa izuba. Ibicuruzwa byinshi byita ku ruhu no kwisiga, nkibishingwe, shampo, hamwe nu menyo wamenyo, akenshi birimo ibintu bya micronize. Nanoparticles ikoreshwa kandi mubikoresho bya elegitoroniki, ibitambara, ikirahure kidashobora kwangirika, nibindi byinshi.
Nanoparticles Irinde izuba risanzwe ntirisige firime yera kuruhu rwawe
Mugihe uhisemo izuba risanzwe ryizuba, ufite amahitamo abiri; abafite nanoparticles nabatayifite. Itandukaniro riri hagati yombi rizagaragara kuruhu rwawe.
Dioxyde de titanium na okiside ya zinc byemejwe na FDA nkibikoresho bisanzwe bitanga izuba. Buriwese atanga umurongo mugari UV kurinda, nubwo dioxyde ya titanium ikora neza mugihe ihujwe na okiside ya zinc cyangwa ikindi kintu cyizuba cyizuba.
Zinc oxyde na dioxyde ya titanium ikora mugaragaza imirasire ya UV kure yuruhu, ikingira uruhu izuba. Kandi bifite akamaro kanini.
Muburyo bwabo busanzwe, butari nano, zinc oxyde na dioxyde ya titanium yera cyane. Iyo byinjijwe mu zuba, bazasiga firime yera igaragara neza kuruhu. Tekereza kurinda ubuzima bwa stereotypical ufite umweru hejuru yikiraro cyizuru - yego, iyo ni okiside ya zinc.
Injira nanoparticles. Imirasire y'izuba ikozwe na micronize zinc oxyde na titanium dioxyde ya rubani mu ruhu neza cyane, kandi ntizisiga inyuma. Ultra-nziza ya nanoparticles ituma izuba ryizuba ridahwitse ariko nkingirakamaro.
Ubwinshi bwubushakashatsi busanga Nanoparticles muri Sunscreen Yizewe
Duhereye kubyo tuzi ubu, ntabwo bisa nkaho nanoparticles ya zinc oxyde cyangwa dioxyde ya titanium yangiza muburyo ubwo aribwo bwose. Nyamara, ingaruka ndende zo gukoresha micronize zinc oxyde na dioxyde de titanium, ni amayobera. Muyandi magambo, nta kimenyetso cyerekana ko gukoresha igihe kirekire ari umutekano rwose, ariko nta kimenyetso na kimwe cyangiza.
Bamwe bibajije umutekano wibi bice bya micronize. Kubera ko ari nto cyane, zirashobora kwinjizwa nuruhu no mumubiri. Ni bangahe byinjizwa nuburyo byinjira cyane biterwa nuburyo buke bwa zinc oxyde cyangwa titanium dioxyde de titanium, nuburyo zitangwa.
Kubitera imigeri, bigenda bite kumubiri wawe niba zinc oxyde cyangwa titanium dioxyde ya nano-ibice byinjijwe? Kubwamahirwe, nta gisubizo gisobanutse kubyo, nabyo.
Hariho abavuga ko bashobora guhangayika no kwangiza ingirabuzimafatizo z'umubiri, kwihuta gusaza haba imbere no hanze. Ariko ubushakashatsi bwinshi bugomba gukorwa kugirango umenye neza inzira imwe cyangwa ubundi.
Dioxyde ya Titanium, iyo ifu yifu kandi ihumeka, byagaragaye ko itera kanseri yibihaha mu mbeba za laboratoire. Dioxyde de micronize nayo yinjira mu ruhu cyane kuruta okiside ya zinc oxyde, kandi dioxyde ya titanium yerekanwe kunyura mu kibanza ikanahagarika inzitizi y'amaraso n'ubwonko.
Wibuke, nubwo, ayo makuru menshi aturuka ku gufata dioxyde ya titanium (kubera ko iboneka mubiribwa byinshi byateguwe hamwe nibijumba). Duhereye ku bushakashatsi bwinshi bwakozwe na micronize ya titanium dioxyde na okiside ya zinc, gusa rimwe na rimwe usanga ibyo bintu biboneka mu ruhu, ndetse no muri icyo gihe byari bike cyane.
Ibyo bivuze ko niyo washyiraho izuba ryizuba ririmo nanoparticles, ntibishobora no gukuramo igice cyambere cyuruhu. Umubare winjiye uratandukanye cyane bitewe nizuba ryizuba, kandi ibyinshi ntabwo bizinjira cyane niba aribyo.
Hamwe namakuru dufite kurubu, izuba ryizuba ririmo nanoparticles bigaragara ko ifite umutekano kandi ikora neza. Ntibisobanutse neza ni ingaruka zo gukoresha igihe kirekire ibicuruzwa bishobora kugira ku buzima bwawe, cyane cyane niba ukoresha ibicuruzwa buri munsi. Na none kandi, nta kimenyetso cyerekana ko gukoresha igihe kirekire gukoresha micronize zinc oxyde cyangwa dioxyde ya titanium byangiza, gusa ntituzi ingaruka bigira (niba bihari) kuruhu rwawe cyangwa kumubiri.
Ijambo Ryiza cyane
Ubwa mbere, wibuke ko kwambara izuba buri munsi nikimwe mubintu byiza ushobora gukora kubuzima bwigihe kirekire cyuruhu rwawe (kandi nuburyo bwiza bwo kurwanya gusaza). Noneho, kudos kuri wewe kugirango ushishikarire kurinda uruhu rwawe!
Hano hari izuba ryinshi risanzwe riraboneka, byombi nano na non-nano, rwose hari ibicuruzwa hanze yawe. Gukoresha izuba ryizuba hamwe na micronize (AKA nano-particle) zinc oxyde cyangwa dioxyde ya titanium bizaguha ibicuruzwa bitarimo paste nkeya kandi bisukuye neza.
Niba uhangayikishijwe na nano-buke, ukoresheje izuba ridafite micronize izuba rizaguha ibice binini bidashobora kwinjizwa nuruhu rwawe. Gucuruza-uzabona firime yera kuruhu rwawe nyuma yo gusaba.
Ubundi buryo niba uhangayikishijwe nukwirinda micronize ya titanium dioxyde de microse, kubera ko ibiyigize aribyo byahujwe nibibazo bishobora kuvura indwara. Wibuke, nubwo, ibibazo byinshi byatewe no guhumeka cyangwa gufata titanium dioxide nanoparticles, kandi bitatewe no kwinjiza uruhu.
Imirasire y'izuba isanzwe, yaba micronize kandi ntabwo, iratandukanye cyane muburyo buhoraho kandi ikumva kuruhu. Noneho, niba ikirango kimwe kitagushimishije, gerageza ikindi kugeza ubonye icyagukorera.
