Umahluko phakathi kwe-1,2-propadiol kunye ne-1,3-propadiol kwi-cosmetics

I-propylene glycol yinto oyibonayo kuluhlu lweentlukwano ze-cosmetics zokufumana yonke imihla. Ezinye zibhalwe njenge-1,2-propadiol kunye nabanye njengeI-1,3-propadiol, yintoni umahluko?
I-1,2-propylene glycol, i-CWESTE 5.5-55, 6, iMolecroula C3H8H8H8H8H8O, yindawo yokuqaliswa kwamachiza, i-Ethanol kunye nezinyibilikisi eziphilayo. Luhlobo olungenamibala kwi-viscous i-vismous kwimeko yesiqhelo, phantse i-odols kwaye imnandi kancinci kwivumba elihle.
Ingasetyenziswa njengearhente emanzi kwi-cosmetics, izinyo kunye nesepha kunye ne-glycerin okanye i-sorebil. Isetyenziswa njenge-arhente emanzi kunye nenqanaba lokufaka ii-hadis kunye nearhente ye-antifreeze.
I-1,3-propleneneI-Glycol, i-Is Nomb. 504-63-2, ifomula yemolekyuli yi-C3H8H8O, ingaba i-vidos, ingenzi, i-Ethanol, i-Ethanol, i-Ether.
Ingasetyenziswa kwi-synthesis yeentlobo ezininzi zeziyobisi, i-Pontuster Ptt ye-Polyster, eziPhakathi ngamayeza kunye ne-Antisobxidants entsha. Yinto engafunekiyo yokuveliswa kwe-polyester engonelanga, iplastiki, i-sulfacnt, i-enulsifier kunye ne-emulsion.
Zombini zinefomula yemolekyuli efanayo kwaye ziyilogo.
I-1,2-proplene Glycol isetyenziswa njenge-arhente ye-antabisicrial okanye i-Pemating Pentres kwi-cosmetics kwiindawo eziphezulu.
Kubuxakeka obuphantsi, isetyenziswa rhoqo njenge-monisturizer okanye uncedo lokucoca.
Kubuxakeka obuphantsi, inokusetyenziswa njengenkqubo ye-SOFPUST yeZithako eziSebenzayo.
Ukucaphukisa ulusu kwaye ukhuseleko kwiingcinezelo ezahlukeneyo zahluke ngokupheleleyo.
I-1,3-propylene Glycol isetyenziswa ikakhulu njenge-solvent kwi-cosmetics. Sisinyibilikisi se-polyol ye-polyol esinceda izithako ze-cosmetic zingena kulusu.
Inegunya eliphezulu lokunyibilikisa kune-glyrin, i-1,2-propadiol kunye ne-1,3-butadiol. Ayinazinto zinamathelayo, akukho mdla wokutsha, kwaye akukho ngxaki zinzima.
Iindlela eziphambili zemveliso ze-1,2-propadiol zezi:
1. Indlela ye-propylene oxide;
I-2. I-propylene yeyona ndlela ye-Oxidation ye-Oxidation;
3. Indlela yotshintshiselwano nge-ESTER; 4.Glycerol Hydrolysis indlela ye-synthesis yendlela.
I-1,3-proplene glycol iveliswa yi:
1. I-Acrolein yendlela;
I-2. Indlela ye-Englone Oxide;
I-3. I-Glycerolsis i-hydrolysis yendlela;
4. Microbiological method.
I-1,3-propylene glycol ibiza kakhulu kune-1,2-proplenene glycone.I-1,3-propleneneI-Glycol inzima ngakumbi ukuvelisa kwaye inesivuno esisezantsi, ke ixabiso layo lisephezulu.
Nangona kunjalo, olunye ulwazi lubonisa ukuba i-1,3-propadiol ingakhathali kwaye ingakhululekanga kulusu kune-1,2-propadinedineol, ifikelela kwinqanaba lesabelo esingakhuselekanga.
Ke ngoko, kwiminyaka yakutshanje, abanye abavelisi bayitshintshe i-1,2-propadiol ene-1,3-propadiol kwizithako ze-cosmetic ukunciphisa ukungonwabi okunokuthi kwenzeke kulusu.
Ukungakhathalelwa kolusu okubangelwe zizicosmetics akunakubangelwa yi-1,2-propadiol okanye i-1,3-propadiol kuphela, kodwa inokubangelwa zizinto ezahlukeneyo. Njengomxholo wabantu wempilo yeziko kunye nokhuseleko olunzulu, imfuno yentengiso eyomeleleyo iya kuqhubela phambili abavelisi abaninzi ukuba baphuhlise iimveliso ezingcono ukuze bahlangabezane neemfuno zabathanda kakhulu!
