He aha ka propanediol?

ʻO Propanediol (PDO) kahi mea hana maʻamau i nā cosmetics a me nā huahana mālama pilikino e like me nā lotion, nā mea hoʻomaʻemaʻe, a me nā ʻili ʻili ʻē aʻe. He kemika like ia me propylene glycol, akā manaʻo ʻia ʻoi aku ka palekana.

Eia naʻe, ʻaʻole i lawa ka nui o nā noiʻi ʻana e hoʻoholo pono ai i ka palekana. Akā ke noʻonoʻo nei i ka ʻikepili o kēia manawa, manaʻo paha ka PDO kumuhana i nā cosmetics i kahi haʻahaʻa haʻahaʻa no nā pilikia koʻikoʻi.

ʻĀpono ʻia ʻo PDO i kēia manawa no ka hoʻohana ʻana i nā cosmetic, i nā kālā i kaupalena ʻia, ma United States, Canada, a me Europe. Akā ʻo ka manaʻo he palekana loa ia? E hoʻomoe mākou a kālailai i nā hōʻike e kōkua iā ʻoe e hana i ka hoʻoholo kūpono no ʻoe a me kou ʻohana.

No hea ia?

ʻO PDO kahi mea kemika i loaʻa mai i ka kānana a ʻaila paha. Hiki ke akāka a melemele iki paha. ʻAneʻane ʻaʻala ʻole. E ʻike paha ʻoe iā PDO i helu ʻia ma ke ʻano he mea hoʻohui i nā ʻano cosmetics a me nā huahana mālama pilikino.

He aha ka mea e hoʻohana ʻia ai i nā mea hoʻonani?

He nui nā home a me nā hana hana a PDO. Loaʻa ia i nā huahana like ʻole, mai ka ʻili kalima a i ka inika paʻi i ka auto antifreeze.


Hoʻohana nā hui Cosmetic iā ia no ka mea he maikaʻi - a me ke kumu kūʻai haʻahaʻa - ma ke ʻano he moisturizer. Hiki iā ia ke kōkua i kou ʻili e loaʻa koke i nā mea hana ʻē aʻe i kāu huahana āu e koho ai. Hiki iā ia ke kōkua i ka dilute i nā mea hana ʻē aʻe.

He aha nā mea hoʻonani e loaʻa ai i loko?

Wahi a ka Environmental Working Group (EWG), e ʻike pinepine ʻoe iā PDO i nā moisturizer maka, serum, a me nā pale maka. Akā hiki iā ʻoe ke loaʻa iā ia i nā huahana mālama pilikino ʻē aʻe, e like me:

  • antiperspirant
  • kala lauoho
  • eyeliner
  • kahua

Pehea e ʻike ʻia ai ma nā papa inoa mea hoʻohui?

Hiki ke helu ʻia ʻo Propanediol ma lalo o nā inoa like ʻole. ʻO nā mea maʻamau e hoʻopili ʻia:

  • 1,3-propanediol
  • trimethylene glycol
  • methylpropanediol
  • propane-1,3-diol
  • 1,3-dihydroxypropane
  • 2-deoxyglycerol

ʻOkoʻa ia ma mua o propylene glycol?

Aia ʻelua mau ʻano like ʻole o PDO: 1,3-propanediol a me 1,2-propanediol, i ʻike ʻia ʻo propylene glycol (PG). I kēia ʻatikala, ke kamaʻilio nei mākou e pili ana i 1,3-propanediol, ʻoiai ua like kēia mau kemika ʻelua.


Ua loaʻa iā PG kekahi mau kaomi maikaʻi ʻole ma ke ʻano he mea mālama ʻili. Ua hāpai nā pūʻulu pale mea kūʻai aku i nā hopohopo i hiki i ka PG ke hoʻonāukiuki i nā maka a me ka ʻili, a he mea ʻike pono ʻia i kekahi.

Manaʻo ʻo PDO ʻoi aku ka palekana ma mua o ka PG. A ʻoiai aia nā kemika ʻelua i ka mole molekiʻi like, ua ʻokoʻa ko lākou mau molekiola. ʻO ia ka ʻano ʻokoʻa o kā lākou hana ke hoʻohana ʻia.

Pili ʻo PG me nā hōʻike he nui o ka huhū o ka ʻili a me ka maka a me ka noʻonoʻo ʻana, ʻoiai ka ʻikepili ma PDO e hōʻemi iki ai i ka pōʻino. No laila, ua hoʻomaka nā hui he nui e hoʻohana iā PDO i kā lākou formulate ma kahi o PG.

Palekana ʻo propanediol?

Manaʻo ʻia ʻo PDO he palekana ke lawe ʻia ma o ka ʻili i nā liʻiliʻi liʻiliʻi mai nā cosmetics topical. ʻOiai hoʻokaʻawale ʻia ʻo PDO ma ke ʻano he mea hoʻonāukiuki i ka ʻili, ʻike ʻo EWG he haʻahaʻa nā pilikia olakino i nā mea hoʻonaninani.

A ma hope o kahi panela o ka poʻe loea e hana nei no ka loiloi Cosmetic Ingredient Review e kālailai i nā ʻikepili o kēia manawa ma propanediol, ua ʻike lākou he palekana ke hoʻohana ʻia i nā mea hoʻonani.


I loko o kahi noiʻi ʻana o propanediol kumuhana ma ka ʻili kanaka, loaʻa wale i nā kānaka noiʻi he hōʻike o ka huhū ma kahi pākēneka haʻahaʻa loa o ka poʻe.

Ua hōʻike ʻia kahi noiʻi ʻē aʻe hiki i kahi propanediol lāʻau kiʻekiʻe ma ka waha ke hana i kahi hopena make i nā ʻiole lab. Akā, i ka hanu ʻana o nāʻiole i ka mahu propanediol, ʻaʻole hōʻike nā mea hōʻike i ka make a i ʻole nā ​​ukiuki koʻikoʻi ʻē aʻe.

Hana ia i nā hopena maʻi ʻaʻa?

ʻO PDO ka mea i hoʻonāukiuki i ka ʻili, akā ʻaʻole i ka hoʻomāhuahua ʻia, i kekahi mau holoholona a me nā kānaka.

No laila, ʻoiai e ʻike paha kekahi poʻe i ka ukiuki ma hope o ka hoʻohana ʻana, ʻaʻole ia he kumu o kahi hopena maoli. Hoʻohui ʻia, ʻoi aku ka liʻiliʻi o ka hoʻonāukiuki ʻana o PDO ma mua o ka PG, kahi i ʻike ʻia i kekahi manawa ke kumu o nā hopena maʻi ʻaihue.

Hiki iā ia ke hoʻololi i ka ʻōnaehana hopohopo?

Aia hoʻokahi hihia i hoʻopaʻa ʻia o PDO e hāʻawi nei i ka make o ke kanaka. Akā pili kēia hihia i ka wahine me ka manaʻo e inu i ka nui o ka antifreeze i loaʻa iā PDO.

ʻAʻohe mea hōʻike i ka nui o nā propanediol i komo i loko o ka ʻili ma o nā mea hoʻonani e alakaʻi i ka make.

He palekana paha no nā wahine hāpai?

ʻAʻohe o nā loiloi hou ʻia e nā hoa i nānā i ka hopena o PDO i ka hāpai ʻana o ke kanaka i kēia manawa. Akā i ka manawa i hāʻawi ʻia ʻia nā holoholona labo nui o PDO, ʻaʻohe kīnā o ka hānau ʻana a i ʻole ka hoʻopau ʻana o ka hāpai keiki.

Ke laina lalo

Wahi a nā ʻikepili o kēia manawa, ʻo ka hoʻohana ʻana i nā mea hoʻonaninani a i ʻole nā ​​huahana mālama pilikino i loaʻa nā propanediol haʻahaʻa ʻaʻole ia e pilikia nui. Ua hoʻonāukiuki paha kahi poʻe liʻiliʻi o ka poʻe i ka ʻili ma hope o ka hōʻike ākea ʻana, akā ʻaʻole ia he mea makaʻu no kekahi mea ʻoi aku ke koʻikoʻi.

Hoʻohui ʻia, hōʻike ʻo propanediol i kahi hoʻohiki e like me kahi koho olakino i propylene glycol ma ke ʻano he mālama ʻili.
