Amagambo ahinnye: Poly dimethyl diallyl ammonium chloride, PDMDAAC, Poly DADMAC, PDADMAC
Mu isi y’ubwiza bw’amavuta yo kwisiga, buri gacupa k’amavuta yo kwisiga na buri lipstick bikubiyemo amabanga menshi ya siyansi. Uyu munsi, turatangaza uruhare rusa n’aho rutazwi ariko rufite akamaro kanini cyane—Poly dimethyl diallyl ammonium chloride.Iyi "ntwali itagaragara y'isi y'ibinyabutabire" irinda bucece ubunararibonye bwacu bw'ubwiza.
Iyo uri kwisiga mu gitondo, hari ubwo wibaza impamvu imisatsi ishobora guhita ihindura imiterere yawe? Poly dimethyl diallyl ammonium chloride ni yo ikora byose. Iyi polymer ya cationic ikora nk'udusimba duto twinshi, ifata neza ku gice cy'umusatsi gifite umuriro mubi. Nyuma y'uko amazi ari muri icyo gice cy'umusatsi ashize, urusobe rworoshye isiga rutuma umusatsi ugumana imiterere yawo ikwiye udakomera nk'insinga z'icyuma, bitandukanye n'imitako gakondo. Igitangaje kurushaho, ishobora gusana ibice by'umusatsi byangiritse, igasubiza umusatsi ukayangana mu gihe uyishyiraho.
Iyo unyeganyeje icupa rya lotion, imiterere yaryo iraryoshye cyane bitewe n'ubumaji bwa P butuma rivamo amavuta.DADMACMu mavuta yo mu bwoko bwa cream, ikoresha uburyo bwo guhuza amavuta n'amazi mu buryo bwa electrostatic kugira ngo ifatanye neza n'ibyiciro by'amavuta n'amazi, birinda gutandukana. Uku "gufatana kwa shimi" kumara igihe kirekire kurusha ibyuma bigabanya ubushyuhe, bigatuma serum igumaho kuva ku gitonyanga cya mbere kugeza ku cya nyuma. Amakuru ya laboratwari agaragaza ko amavuta yongerewemoPDADMACifite ubushobozi bwo kugumana uruhu ku kigero cya 40%, ari nayo mpamvu ibikoresho byo kwita ku ruhu byo ku rwego rwo hejuru biyikunda.
PDADMACMu lipsticks hagaragara ubwiza bubiri. Nk'ikintu gifata ibara, gitanga ikwirakwizwa ry'uduce tw'ibara, kikarinda ko habaho ibisebe biteye isoni mu gihe cyo kuyikoresha; nk'ikintu gitanga ibara, ikora firime ihumeka kugira ngo irangire igihe kirekire. Igitangaje kurushaho, ni uko imiterere yayo yoroshye ituma iba amahitamo meza yo kwisiga ku bana, aho amabwiriza y'ubwiza y'Umuryango w'Ubumwe bw'u Burayi yemera cyane cyane ko idafite allergies nyinshi.
Abahanga mu bya siyansi barimo gushakisha andi mahirwe yoPDADMAC: kongera ubushobozi bwo gukoresha imiti igabanya ubukana bw'imirasire y'izuba mu mavuta yo kwisiga ndetse no kunoza uburyo ibintu bikora mu mashiko binjira. Ubuvumbuzi buherutse kuvumburwa na laboratwari yo muri Koreya y'Epfo bugaragaza koPoly DADMACuburemere bwihariye bwa molekile bushobora guteza imbere imikorere ya kolajeni, bishobora gutangaza iterambere rishya mu rwego rwo kurwanya gusaza.
Ikigo Mpuzamahanga cy’Ibintu Biryoshye (INCI) gifite amabwiriza akaze agenga ikoreshwa ryaPoly DADMACkugira ngo habeho uburinganire hagati y’umutekano n’imikorere myiza. Kubera ko abaguzi barushaho gushyira imbere “isuku,” ubushakashatsi n’iterambere ry’ibikomoka ku binyabuzimaPoly DADMACiri kwihuta, kandi dushobora kubona ubwiza bukomoka ku bimera mu gihe kizaza.
Kuva ku musatsi kugeza ku minwa, inyuma y'izina rihindura ururimi ryaPoly DADMACUbuhanga bw'abahanga benshi mu by'ubwiza bw'ibintu burimo ubwenge rusange. Bitwibutsa ko ikoranabuhanga nyaryo ry'ubwiza rikunze kwihisha mu isi y'uturemangingo tutagaragara. Ubutaha nukoresha amavuta yo kwisiga, tekereza uburyo aba bantu batagaragara barimo kuvugurura ubwiza bwawe buhoro buhoro.
