Imashini zishyushya umwuka zifiteImpumuro nziza zitandukanye za 320ml, nk'impumuro y'indabyo imwe (jasmine, roza, osmanthus, lily of the valley, gardenia, lily, nibindi), impumuro y'ibirungo, nibindi. Ariko muri rusange bigizwe na ether, essence n'ibindi bikoresho. Impumuro z'umwuka zishobora no kwitwa "impumuro z'ibidukikije". Mu myaka ya vuba aha, impumuro zitandukanye z'umwuka zagiye zikundwa cyane.

Imiti ikoreshwa mu kuvura umwuka iboneka ku isoko ubu iboneka mu buryo butandukanye. Iyo itandukanyijwe n'uko igaragara, ishobora kugabanywamo ubwoko butatu: ibikomeye, amazi, n'umwuka.

Imashini zitunganya umwuka w’amazi muri rusange zikoresha uduce tw’urukiramende cyangwa udupapuro twa filter nk’ibintu bihumanya ikirere, zigashyirwa mu gikoresho cy’impumuro y’amazi kugira ngo zimure impumuro y’umwuka w’amazi. “Impumuro y’imodoka” ishyirwa ku rukuta rw’umushoferi mu modoka ni ubwoko bw’ibicuruzwa. Ingorane ni uko amazi azasuka iyo agakoresho kaguye. Kubwibyo, vuba aha, bamwe mu bakora ibikoresho bikozwe mu “byapa bito”, bishobora gupfundikirwa umupfundikizo nyuma yo kuzuza impumuro, kandi impumuro ikazava buhoro buhoro ku rukuta rw’agakoresho. Imashini zitunganya umwuka w’amazi zo mu bwoko bwa aerosol nizo zikunzwe cyane muri iki gihe. Zifite ibyiza byinshi: zoroshye gutwara, zoroshye gukoresha, kandi zihuta gukwirakwiza impumuro.

Kuri ubu, hari ubwoko bwinshi bw'ibikoresho bishyushya umwuka ku isoko. Ibisanzwe bigizwe na diethyl ether, uburyohe n'ibindi bintu. Ibikoresho byo mu macupa byongerwamo propane, butane, dimethyl ether n'ibindi bikoresho bya shimi. Gukoresha iki gikoresho bishyushya umwuka bishobora guhisha impumuro idasanzwe yo mu nzu by'agateganyo binyuze mu gutera impumuro mbi ntibishobora kongera ubwiza bw'umwuka, kuko ibice byacyo bidashobora kubora imyuka mibi, kandi biragoye kongerera umwuka umwuka neza. Nyuma y'uko umubiri w'umuntu uhumeka umwuka ushyushye ukoresheje umwuka uhumura neza, uhita ukururwa no kwinjira mu bwonko, bigatuma wumva "udahumeka".

Dukurikije isesengura ry’inzobere mu by’imiti, akamaro k’uyu muti kangana n’ak’imiti igabanya ububabare mu mitsi yo mu mutwe. Iyo umuntu ahumūra agize ibyiyumvo bimwe na bimwe, atangira kwishingikiriza ku byo atekereza. Umuntu uba afite ibiyobyabwenge ahitamo imiti akunda kandi agahitamo kuyihumeka kenshi buri munsi, bigatuma arwara uburozi budakira. Lead na benzene byongewe muri lisansi bishobora gutera indwara ya neuritis, indwara yo mu mitsi yo hagati cyangwa iyo mu mitsi yo mu gice cy’imbere, kandi bishobora no gutera ibimenyetso nko kubura amaraso no kunanirwa kw’imitsi; imiti ihindagurika nk’iy’umusemburo nka ethane, nk’amavuta ya karamu n’imiti ikuraho irangi, ni byo nyirabayazana w’amaraso adahagije, kubura ibiryo mu nda, kubura amaraso mu mubiri, no kwangirika mu nda.

Kubwibyo, abahanga bavuga ko gufungura amadirishya kenshi no gusukura ibidukikije hakoreshejwe umwuka mwiza kandi uhumura ari bwo buryo bwa mbere bwo guhumeka neza; ubundi buryo ni ubwoko bushya bw'ibikoresho bihumura neza mu mwuka bifite ibikoresho biva mu bimera karemano. Ubwoko bwa nyuma bw'ibikoresho byizewe kandi birengera ibidukikije buzwi cyane mu bihugu by'amahanga bifite sisitemu zo gusukura umwuka, harimo isuku y'umwuka n'imashini zikuraho impumuro mbi mu mwuka. Bigabanya ingano y'ibintu bihumanya ikirere, ntibirimo chlorofluorocarbons, kandi ntacyo bitwaye ku bantu no ku bidukikije.
