Wafashe icyemezo cy'uko gukoresha amavuta akingira izuba ari byo bikubereye. Wenda wumva ari byo byiza kuri wowe no ku bidukikije, cyangwa amavuta akingira izuba arimo ibintu by'ubukorikori bitera uruhu rwawe kwihagararaho cyane.
Hanyuma wumva ibyerekeye "nanoparticles" muri zimwe mu miti irinda izuba karemano, hamwe n'amakuru ateye ubwoba kandi avuguruzanya kuri ibyo bice by'umubiri biguha umwanya wo guhagarara. Mu by'ukuri, ese guhitamo imiti irinda izuba karemano bigomba kuba urujijo gutya?
Kubera amakuru menshi cyane, bishobora kugaragara nk'aho ari ibintu biremereye. Reka rero duce urusaku maze turebe ubudakemwa ku bice bito by'isuku biri mu ruhu, umutekano wabyo, impamvu uzishaka mu ruhu rwawe n'igihe utazishaka.
Uduce duto tw’ingirabuzimafatizo (Nanoparticles) ni iki?
Uduce duto cyane tw’ikintu runaka. Uduce duto cyane dufite ubugari bwa nanometero 100. Kugira ngo dutange ishusho, nanometero ni nto inshuro 1000 ugereranyije n’ubugari bw’umugozi umwe w’umusatsi.
Nubwo uduce duto cyane dushobora kuremwa mu buryo busanzwe, nk'udutonyanga duto cyane twa spray yo mu nyanja, uduce duto cyane cyane dukorerwa muri laboratwari. Ku bijyanye n'isuku y'izuba, uduce duto cyane cyane ni zinc oxyde na titanium dioxide. Ibi bintu bicibwamo uduce duto cyane mbere yo kongerwa ku isuku y'izuba.
Uduce duto tw’izuba twatangiye kuboneka mu miti irinda izuba mu myaka ya 1980, ariko ntabwo twakomeje kuboneka kugeza mu myaka ya 1990. Muri iki gihe, ushobora gutekereza ko imiti irinda izuba isanzwe irimo zinc oxide na/cyangwa titanium dioxide ari uduce duto cyane keretse iyo byavuzwe ukundi.
Amagambo "nano" na "micronized" ni amagambo asa. Bityo, izuba rifite "micronized zinc oxide" cyangwa "micronized titanium dioxide" ririmo uduce duto.
Uduce duto tw’izuba ntituboneka gusa mu mavuta yo kwisiga akingira izuba. Ibikoresho byinshi byo kwita ku ruhu no kwisiga, nka fondasiyo, shampoo, n’amenyo y’amenyo, akenshi biba birimo ibintu bya mikoroni. Uduce duto tw’izuba dukoreshwa kandi mu bikoresho by’ikoranabuhanga, imyenda, ikirahure kidashwanyagurika, n’ibindi.
Uduce duto tw'izuba turinda izuba gusiga uruhu rwawe uruhu rwera
Mu guhitamo amavuta akingira izuba asanzwe, hari amahitamo abiri; afite uduce duto tw’izuba n’adafite. Itandukaniro riri hagati yabyo rizagaragara ku ruhu rwawe.
Diyozede ya titaniyumu na okiside ya zinki byombi byemejwe na FDA nk'ibintu bisanzwe bikingira izuba. Buri kimwe gitanga uburinzi bwa UV ku miterere migari, nubwo diyozede ya titaniyumu ikora neza iyo ivanze na okiside ya zinki cyangwa ikindi kintu gikoze ku zuba.
Okiside ya zinki na dioxyde ya titanium bikora mu kurekura imirasire ya UV iva ku ruhu, bikingira uruhu izuba. Kandi bigira akamaro kanini.
Mu buryo busanzwe, butangana na nano, zinc oxyde na titanium dioxide ni umweru cyane. Iyo bishyizwe mu ruhu, bisiga agahu k'umweru kadasobanutse neza ku ruhu. Tekereza ku muntu ukunda kurokora ubuzima ufite umweru ku kiraro cy'izuru—yego, ni zinc oxyde.
Shyiramo uduce duto cyane. Indabyo z'izuba zikozwe muri mikroni zinc oxyde na titanium dioxide zisiga mu ruhu neza cyane, kandi ntizisiga inyuma isura ishaje. Uduce duto cyane tw'izuba dutuma imirasire y'izuba idahinduka ariko ikagira akamaro kanini.
Ubushakashatsi bwinshi bwagaragaje ko uduce duto twa nano mu cyuma gikingira izuba tudakoresha ikoranabuhanga
Dukurikije ibyo tuzi ubu, bisa nkaho uduce duto twa zinc oxide cyangwa titanium dioxide tutangiza mu buryo ubwo aribwo bwose. Ariko, ingaruka z'igihe kirekire zo gukoresha zinc oxide na titanium dioxide, ni amayobera make. Mu yandi magambo, nta gihamya cy'uko kuyikoresha igihe kirekire ari umutekano rwose, ariko nta gihamya cy'uko ari bibi.
Hari abibajije ku mutekano w'utwo duce twa mikoroni. Kubera ko ari duto cyane, dushobora kwinjizwa n'uruhu no kwinjira mu mubiri. Ingano y'ibintu byinjizwa n'uburyo byinjira mu buryo bwimbitse biterwa n'uburyo uduce twa zinc oxide cyangwa titanium dioxide ari duto, n'uburyo bitangwa.
Ku birebana n'amafi, ni iki kibaho ku mubiri wawe iyo utunyangingo twa zinc oxide cyangwa titanium dioxide nano-particles twinjijwemo? Ikibabaje ni uko nta gisubizo cyumvikana kuri ibyo.
Hari abavuga ko bishobora gutuma uturemangingo tw’umubiri wacu duhangayika kandi bikangiza uturemangingo, bigatuma umubiri wacu urushaho gusaza imbere no hanze. Ariko hakenewe ubushakashatsi bwinshi kugira ngo hamenyekane neza uburyo bumwe cyangwa ubundi.
Dioxyde ya titanium, iyo iri mu ifu yayo kandi ihumekwa, byagaragaye ko itera kanseri y'ibihaha mu mbeba zo muri laboratwari. Dioxyde ya titanium ifite mikroni nayo yinjira mu ruhu cyane kurusha dioxyde ya zinc ifite mikroni, kandi dioxyde ya titanium yagaragaye ko inyura mu nyababyeyi ikayihuza n'urukuta rw'amaraso n'ubwonko.
Ariko, ibuka ko amakuru menshi aturuka ku kunywa dioxyde ya titanium (kuko iboneka mu biribwa byinshi byateguwe mbere n'ibintu biryoshye). Mu bushakashatsi bwinshi bwakozwe ku ruhu, dioxyde ya titanium na oxyde ya zinc ikoreshwa mu buryo bworoshye, rimwe na rimwe ibi bintu biboneka mu ruhu, kandi mbere byari biri mu rugero ruto cyane.
Ibyo bivuze ko nubwo washyiramo agakoresho ko kwisiga karimo utunyangingo duto, gashobora no kutarenga urwego rwa mbere rw'uruhu. Ingano y'ingufu ziterwa n'ingufu ziterwa n'uko zikozwe, kandi inyinshi muri zo ntizishobora kwisuka cyane niba zirimo.
Dukurikije amakuru dufite ubu, amavuta yo kwisiga arimo utunyangingo duto asa nkaho ari meza kandi afite akamaro cyane. Nta gisobanuro cyumvikana neza ku ngaruka zo gukoresha uyu muti igihe kirekire bishobora kugira ku buzima bwawe, cyane cyane niba ukoresha uyu muti buri munsi. Na none, nta gihamya cy'uko gukoresha igihe kirekire zinc oxide cyangwa titanium dioxide ari bibi, ntabwo tuzi ingaruka bigira (niba bihari) ku ruhu rwawe cyangwa ku mubiri wawe.
Ijambo rivuye kuri Verywell
Ubwa mbere, ibuka ko kwambara amavuta yo kwisiga izuba buri munsi ari kimwe mu bintu byiza ushobora gukora kugira ngo uruhu rwawe rugire ubuzima bwiza igihe kirekire (kandi ni bwo buryo bwiza bwo kurwanya gusaza). Rero, ndagushimira kuba waragize uruhare mu kurinda uruhu rwawe!
Hari imiti myinshi irinda izuba isanzwe iboneka, yaba nano cyangwa non-nano, nta gushidikanya ko hari ikintu cyiza kuri wewe. Gukoresha imiti irinda izuba irimo mikoronize (AKA nano-particle) zinc oxide cyangwa titanium dioxide bizaguha ikintu kidakomeye kandi gisukuye neza.
Niba uhangayikishijwe n'uduce duto tw'izuba, gukoresha umuti urinda izuba udakoresha mikoroni bizaguha uduce duto tudakunze kwinjirwa n'uruhu rwawe. Ikibazo ni uko uzabona agahu k'umweru ku ruhu rwawe nyuma yo kurusiga.
Indi nzira niba uhangayikishijwe ni ukwirinda burundu ibintu bya titanium dioxide, kuko iki kintu ari cyo cyagize uruhare mu bibazo by’ubuzima. Ariko, ibuka ko ibibazo byinshi muri ibi byaterwaga no guhumeka cyangwa kunywa titanium dioxide nanoparticles, atari ukunywa uruhu.
Indabyo zisiga izuba karemano, zaba izifite mikoroni cyangwa izidafite mikoroni, ziratandukanye cyane mu buryo zigaragara ku ruhu. Niba rero ikirango kimwe kitagushimishije, gerageza ikindi kugeza ubonye ikikubereye..
