Ngongo Kirihou: Te Otinga Tākai Tino Pai mō ngā Whakapaipai Kirihou
Ko te maha o ngā rauemi e whakamahia ana e ngā ngongo kirihou e wehewehe ana i a rātou. Ka tukuna e ngā ngongo LDPE (polyethylene iti-kiato) he tino ngāwari mō te pēhi, he mea pai mō ngā kirikiri māmā me ngā hua haere. Mō ngā tauira kirikiri matotoru ake, mō ngā mea rānei kei roto he waikawa, ka whakaratohia e te HDPE (polyethylene teitei-kiato) he ātete matū pai ake me te hanganga pakari. Ko ngā ngongo maha-paparanga kua whakakotahihia me ngā ārai EVOH he mea whakarerekē i ngā kēmu mō ngā kirikiri whai rawa (hei tauira, te huaora C, te retinol rānei), e aukati ana i te urunga o te hāora hei pupuri i te kaha me te whakaroa i te roa o te oranga tae atu ki te 36 marama.
Kāore te oranga tonutanga e whakaarohia ana i muri iho. Ka whakaitihia e ngā ngongo kirihou PCR (post-consumer recycled) ngā tapuwae waro me te pupuri tonu i te pakari, e hangai ana ki te 42% o ngā mano tau e whakatairanga ana i ngā takai hoa-taiao. Ka tukuna e ngā ngongo kirihou koiora-tō he huarahi waro-kore, he tino pai mō ngā waitohu ataahua ma e rapu ana i ngā otinga hangarua, mai i ngā tipu. Kāore ēnei kōwhiringa e whakaiti i te mahi - ka tutuki i a rātou ngā paerewa ātete turuturu (tae atu ki ngā whakamātautau maturuturu 1-mita) ki ngā kirihou tuku iho.
Ka whakarei ake te auahatanga hoahoa i te whakamahinga me te waitohu. Mā ngā taupoki hurihuri me ngā pūwero tika ka taea te tuku whakahaere, ka whakaitihia te para mō ngā hanganga tiēre utu nui. Ka hono pai ngā pito o te taputapu silicone ki ngā ngongo kirihou, ka whakaratohia he tono akuaku, he tono kua tohua mō ngā tiēre kanohi, ngā maimoatanga ira rānei. Ko ngā kōwhiringa whakaritenga—mai i ngā mutunga matte ki te tānga tae-katoa—ka whakapakari i te tuakiri waitohu me te whakatutuki i ngā whakaritenga tapanga EU/UK mō ngā rārangi INCI me ngā tohu PAO.
Mō ngā waitohu e whakanui ana i te hanga, he pai rawa atu te pai o ngā ngongo kirihou. Ka taea e ngā raina whakaputa tere te whakaputa tae atu ki te 20,000 waeine ia hāora, me ngā kōwhiringa rarawe e wātea ana i roto i ngā rahinga mai i te 5,000 wahi. Ahakoa mō ngā kirikiri kaukau hokohoko nui, mō ngā serum anti-pakeke papai rānei, ka urutau ngā ngongo kirihou ki ngā momo hanganga kirikiri, ngā tono ture, me ngā tumanakohanga a te kaihoko—e whakaatu ana he nui atu i te ipu anake, engari he hoa tākai rautaki.
