Kodi propanediol ndi chiyani?

Propanediol (PDO) ndichinthu chodziwika bwino popangira zodzoladzola ndi zinthu zodzisamalira monga lotions, zotsukira, ndi mankhwala ena akhungu. Ndi mankhwala ofanana ndi propylene glycol, koma amaganiza kuti ndi otetezeka.

Komabe, sipanakhale maphunziro okwanira kuti atsimikizire bwinobwino za chitetezo. Koma polingalira za zomwe zilipo pakadali pano, zikuwoneka kuti PDO yapakhungu yodzikongoletsera imakhala pachiwopsezo chochepa cha zovuta zazikulu.

PDO tsopano ikuvomerezedwa kuti igwiritsidwe ntchito zodzoladzola, zoletsa zochepa, ku United States, Canada, ndi Europe. Koma kodi izi zikutanthauza kuti ndi zotetezeka kwathunthu? Tidzaika ndikusanthula maumboni omwe angakuthandizeni kupanga chisankho choyenera kwa inu ndi banja lanu.

Zimachokera kuti?

PDO ndi mankhwala omwe amachokera ku chimanga kapena mafuta. Zitha kukhala zomveka kapena zachikasu pang'ono. Ndipafupifupi opanda fungo. Muyenera kuti mupeze PDO yolembedwera ngati chophatikizira pazodzola zilizonse zodzikongoletsera ndi zinthu zina zokometsera.

Amagwiritsidwa ntchito bwanji mu zodzoladzola?

PDO imagwiritsa ntchito zambiri zapakhomo. Amapezeka muzinthu zosiyanasiyana, kuyambira kirimu cha khungu mpaka inki yosindikiza mpaka kuyimitsa magalimoto.

Makampani opanga zodzikongoletsera amagwiritsa ntchito chifukwa ndiwothandiza - komanso wotsika mtengo - monga mafuta onunkhira. Ikhoza kuthandizira khungu lanu kuyamwa msanga zosakaniza zina pazomwe mungasankhe. Itha kuthandizanso kuchepetsa zina zopangira.

Ndi zodzoladzola ziti zomwe zimapezeka?

Malinga ndi Environmental Working Group (EWG), mupeza PDO nthawi zambiri m'malo opukutira nkhope, ma seramu, ndi masks kumaso. Koma mutha kupezanso pazinthu zina zosamalira anthu, kuphatikiza:

• wotsutsa
• mtundu wa tsitsi
• eyeliner
• maziko

Zimawoneka bwanji pamndandanda wazosakaniza?

Propanediol imatha kulembedwa mayina angapo osiyanasiyana. Zowonjezeka ndizo:

• 1,3-mankhwala
• trimethylene glycol
• methylpropanediol
• katundu-1,3-diol
• 1,3-dihydroxypropane
• 2-deoxyglycerol

Kodi ndi yosiyana ndi propylene glycol?

Pali mitundu iwiri yosiyana ya PDO: 1,3-propanediol ndi 1,2-propanediol, yotchedwanso propylene glycol (PG). Munkhaniyi, tikukamba za 1,3-propanediol, ngakhale mankhwala awiriwa ali ofanana.

PG yalandila posachedwa atolankhani olakwika ngati chida chosamalira khungu. Magulu oteteza makasitomala adadzetsa nkhawa kuti PG imatha kukwiyitsa maso ndi khungu, ndipo imadziwika ndi ena.

PDO imaganiziridwa kuti ndiyotetezeka kuposa PG. Ndipo ngakhale mankhwala awiriwa ali ndi mawonekedwe ofanana ndendende, mawonekedwe ake ndi osiyana. Izi zikutanthauza kuti amachita mosiyanasiyana akagwiritsidwa ntchito.

PG imalumikizidwa ndi malipoti angapo okhumudwitsa khungu ndi maso ndikulimbikitsa, pomwe zomwe zili pa PDO sizowopsa. Chifukwa chake, makampani ambiri ayamba kugwiritsa ntchito PDO m'njira zawo m'malo mwa PG.

Kodi propanediol ndi yotetezeka?

PDO nthawi zambiri imalingaliridwa kuti ndiyotetezeka ikamalowetsedwa pakhungu pang'ono kuchokera kuzodzola zodzikongoletsera. Ngakhale PDO imagawidwa ngati yosasangalatsa khungu, EWG imanena kuti kuopsa kwa zodzoladzola ndikotsika.

Ndipo pambuyo poti gulu la akatswiri omwe amagwirira ntchito ku Cosmetic Ingredient Review atasanthula zomwe zaposachedwa pa propanediol, adazipeza zili zotetezeka zikagwiritsidwa ntchito zodzikongoletsera.

Pofufuza za topical propanediol pakhungu la anthu, ofufuza adangopeza umboni wakukwiya pagulu lochepa kwambiri la anthu.

Kafukufuku wina adawonetsa kuti propanediol wamankhwala apamwamba pakamwa amatha kupha makoswe a labu. Koma, makoswe atapumira nthunzi ya propanediol, omwe amayesedwayo sanayese kufa kapena kukwiya kwambiri.

Kodi zimayambitsa zovuta zina?

PDO yadzetsa mkwiyo pakhungu, koma osalimbikitsa, munyama ndi anthu ena.

Chifukwa chake, ngakhale anthu ena atha kukhumudwa atagwiritsa ntchito, sizikuwoneka kuti zimayambitsa kuchitapo kanthu kwenikweni. Kuphatikiza apo, PDO siyokwiyitsa kwambiri kuposa PG, yomwe imadziwika kuti nthawi zina imayambitsa zovuta zina.

Kodi zingakhudze dongosolo lamanjenje?

Pali nkhani imodzi yolembedwa ya PDO yomwe imathandizira kufa kwa munthu. Koma mlanduwu umakhudza mayi yemwe amamwa mwadala ma antifreeze omwe anali ndi PDO.

Palibe umboni woti kuchuluka kwa mankhwala osokoneza bongo omwe amalowetsedwa kudzera pakhungu kudzera mu zodzoladzola zitha kubweretsa imfa.

Kodi ndizotetezeka kwa amayi apakati?

Palibe kafukufuku wowunikiridwa ndi anzawo omwe adayang'ana momwe PDO imakhudzira kutenga pakati kwa anthu mpaka pano. Koma ziweto za labu zikagwiritsidwa ntchito kwambiri ndi PDO, palibe zopindika zobereka kapena kutha kwa mimba komwe kunachitika.

Mfundo yofunika

Malinga ndi zomwe zapezeka pano, kugwiritsa ntchito zodzoladzola kapena zinthu zosamalira anthu zomwe zimakhala ndi mankhwala ochepa a propanediol sizowopsa. Chiwerengero chochepa cha anthu atha kukhala kuti adakwiyitsa khungu atawonekera kwambiri, koma sikuwoneka ngati chiopsezo china chilichonse chowopsa.

Kuphatikiza apo, propanediol imawonetsa lonjezo ngati njira yathanzi m'malo mwa propylene glycol ngati chopangira khungu.
