Ipropanediol kwizithambiso: Ngaba ikhuselekile? - Zempilo
Ipropanediol kwizithambiso: Ngaba ikhuselekile? - Zempilo

Umxholo

Yintoni ipropanediol?

Ipropanediol (PDO) sisithako esiqhelekileyo kwizithambiso kunye neemveliso zokhathalelo lomntu ezifana nezinto zokuthambisa, zokucoca kunye nolunye unyango lolusu. Yikhemikhali efana nepropylene glycol, kodwa kucingelwa ukuba ikhuselekile.

Nangona kunjalo, khange kubekho zifundo zaneleyo okwangoku ukumisela ngokuqinisekileyo ukhuseleko. Kodwa kuthathelwa ingqalelo idatha yangoku, kunokwenzeka ukuba umxholo we-PDO kwizithambiso uthwala umngcipheko ophantsi weengxaki ezinzulu.

I-PDO okwangoku ivunyelwe ukusetyenziswa kwizithambiso, kwimilinganiselo ethintelweyo, eUnited States, Canada nase Europe. Kodwa ngaba oko kuthetha ukuba kukhuseleke ngokupheleleyo? Siza kubeka kwaye sihlalutye ubungqina bokukunceda wenze isigqibo esifanelekileyo kuwe nakusapho lwakho.

Ivela phi?

I-PDO sisixhobo semichiza esivela kumbona okanye kwipetroleum. Inokucaca okanye ityheli kancinci. Iphantse yanevumba. Kusenokwenzeka ukuba ufumane i-PDO edweliswe njengesithako kuninzi kakhulu kudidi lwezithambiso kunye neemveliso zokhathalelo lomntu.

Kusetyenziselwa ntoni kwizithambiso?

I-PDO inokusetyenziswa kwamakhaya amaninzi kunye nokuvelisa. Itholakala kwiintlobo ezahlukeneyo zeemveliso, ukusuka kwikrimu yesikhumba ukuya kwiprinta inki ukuya kwi-auto antifreeze.


Iinkampani zezithambiso ziyayisebenzisa kuba iyasebenza- kunye neendleko eziphantsi- njengesithambisi. Inokukunceda ulusu lwakho luthathe ngokukhawuleza ezinye izinto kwimveliso oyithandayo. Inokukunceda ukunciphisa ezinye izinto ezisebenzayo.

Zeziphi izinto zokuthambisa ezifumaneka kuyo?

NgokweQela eliSebenzayo lokusiNgqongileyo (i-EWG), uyakufumana i-PDO rhoqo kwizithambisi zobuso, iiserum, kunye neemaski zobuso. Kodwa unokuyifumana kwezinye iimveliso zononophelo, kubandakanya:

  • Abaphikisi
  • umbala wenwle
  • eyeliner
  • isiseko

Ivela njani kuluhlu lwezithako?

Ipropanediol inokudweliswa phantsi kwamagama ahlukeneyo. Ezona zixhaphakileyo zibandakanya:

  • 1,3-ipropanediol
  • i-trimethylene glycol
  • imethylpropanediol
  • propane-1,3-diol
  • 1,3-dihydroxypropane
  • I-2-deoxyglycerol

Ngaba yahlukile kunepropylene glycol?

Kukho iindlela ezimbini ezahlukileyo ze-PDO: 1,3-propanediol kunye ne-1,2-propanediol, ekwabizwa ngokuba yipropylene glycol (PG). Kule nqaku, sithetha nge-1,3-propanediol, nangona ezi khemikhali zimbini zifana.


Kutshanje i-PG ifumene amaphepha-ndaba amabi njengesixhobo sokhathalelo lolusu. Amaqela akhusela abathengi aphakamise inkxalabo yokuba i-PG inokucaphukisa amehlo kunye nolusu, kwaye yinto eyaziwayo kwabanye.

I-PDO kucingelwa ukuba ikhuselekile kune-PG. Kwaye nangona ezi khemikhali zimbini zinendlela efanayo yemolekyuli, ulwakhiwo lweemolekyuli zahlukile. Oko kuthetha ukuba baziphatha ngokwahlukileyo xa besetyenziswa.

I-PG inxulunyaniswa neengxelo ezininzi zolusu kunye nokucaphuka kwamehlo kunye novakalelo, ngelixa idatha ekwi-PDO ingenabungozi kangako. Ke, iinkampani ezininzi ziqalisile ukusebenzisa iPDO kwiifomula zazo endaweni ye-PG.

Ngaba ipropanediol ikhuselekile?

I-PDO ngokubanzi kucingelwa ukuba ikhuselekile xa ifunxwa eluswini ngesixa esincinci kwizithambiso zokoqobo. Nangona i-PDO ihlelwe njengolusu olucaphukisayo, i-EWG iqaphela ukuba umngcipheko wempilo kwizithambiso uphantsi.

Kwaye emva kwephaneli leengcali elisebenzela uVavanyo lweZithako zeCosmetic lihlalutye idatha yangoku kwipropanediol, bayifumana ikhuselekile xa isetyenziswa kwizithambiso.


Kuphononongo lwe-propanediol yolusu kulusu lomntu, abaphandi bafumanise ubungqina bokucaphuka kwipesenti esezantsi kakhulu yabantu.

Olunye uphononongo lubonise ukuba idosi ephezulu yepropanediol kwifom yomlomo inokuba nefuthe elibulalayo kwiigundane zebhu. Kodwa, xa iigundane zangenisa umphunga wepropanediol, izifundo zovavanyo azibonisanga kusweleka okanye okunye ukucaphuka okunzulu.

Ngaba ibangela ukusabela komzimba?

I-PDO ibangele ulusu olucaphukisayo, kodwa hayi uvakalelo, kwezinye izilwanyana nabantu.

Ke, ngelixa abanye abantu benokufumana ukucaphuka emva kokusetyenziswa, akubonakali ngathi kubangela impendulo eyiyo. Ukongeza, i-PDO ayicaphukisi kangako kune-PG, eyaziwayo ngamanye amaxesha inokubangela ukungahambelani komzimba.

Ngaba inokuchaphazela inkqubo ye-nervous?

Inye imeko ebhaliweyo ye-PDO enegalelo ekuswelekeni komntu. Kodwa eli tyala lalibandakanya umntu wasetyhini ngabom okusela isixa esikhulu se-antifreeze equlathe i-PDO.

Akukho bungqina bokuba amanani amancinci epropanediol afunxwe eluswini ngezithambiso kungakhokelela ekufeni.

Ngaba kukhuselekile kubafazi abakhulelweyo?

Akukho zifundo ziphononongwe ngoontanga ezijonge ifuthe le-PDO ekukhulelweni komntu okwangoku. Kodwa xa izilwanyana zaselebhu zanikwa idosi ephezulu ye-PDO, akukho ziphene zokuzalwa okanye ukupheliswa kokukhulelwa okwenzekileyo.

Umgca wezantsi

Ngokwedatha yangoku, ukusebenzisa izinto zokuthambisa okanye iimveliso zokhathalelo lomntu eziqulethe izixa eziphantsi zepropanediol ayibeki mngcipheko omkhulu. Inani elincinci labantu linokuba nolusu olucaphukisayo emva kokubhengeza okuninzi, kodwa akubonakali ngathi kungumngcipheko kuyo nayiphi na into ebaluleke ngakumbi.

Ukongeza, ipropanediol ibonisa isithembiso njengenye indlela esempilweni yepropylene glycol njengesixhobo sokhathalelo lolusu.
