Ngenxa yokuba i-propylene glycol inokunyibilika kakuhle kwiintlobo ezahlukeneyo zeziqholo, ikwasetyenziswa njenge-solvent kunye ne-softener ye-cosmetics. I-Pigbolly ikwasetyenziswa njengesinyibilikisi sezinto zokufuma kwecuba, izinto zokuthintela ukubola, izixhobo zokulungisa ukutya, ioyile yokuthambisa kunye ne-inki yokuphawula ukutya. Isisombululo se-hydraulic se-propylene glycol sisixhobo esisebenzayo sokuthintela ukukhenkceza.
7. Njengesithwali samayeza, iarhente yamayeza eenxalenye. Ingasetyenziswa njengesithambisi kwizithambiso, izithambisi, izinyibilikisi, njl. Ishishini lecuba lingasetyenziswa njengomsi, izithambisi zecuba, izigcini, njl. Ishishini lokutya lisetyenziswa njengevumba elimnandi, izinyibilikisi zepigment ezityiwayo, iiarhente ezithambileyo zokupakisha ukutya zeChemicalbook, izincamathelisi zokutya, njl. Ingasetyenziselwa ukuvelisa iiresini zepolyester ezingagcwaliyo, kunye neeplastiki, iiarhente eziphelelwe ngamanzi emzimbeni, ii-surfactants, iiarhente zokupholisa, izihlanganisi, njl. Ingasetyenziswa nakwimizi-mveliso efana nepeyinti, izibulali-zinambuzane, iingubo kunye neminye imizi-mveliso.
8. Ukususwa kweenqwelo moya, i-ejenti ekhenkcezisiweyo kunye nefriji, ukutya neziqholo, ii-ejenti zeziqholo, izinto zokuthambisa kunye neemveliso zempilo yomntu, ukudluliselwa kobushushu, ulwelo lwe-hydraulic kunye ne-brake, ipeyinti kunye neengubo, ukutya kwezilwanyana zasekhaya/ukutya kwezilwanyana, amayeza, i-polyurethane, i-polyurethane, i-polyurethane, i-polyurethane, i-polyurethane, i-polyurethane, i-polyurethane, i-polyurethane, i-polyurethane, i-polyurethane, i-Unsaturated polyester resin.
9. Isinyibilikisi, ukwenziwa kwezinto eziphilayo, i-antifreeze, i-plasticizer, i-sterilizer. Imigangatho yohlalutyo lwe-gas chromatography. Ulwelo oluzinzileyo lwe-gas chromatography (ubushushu obuphezulu be-150 ° C, i-solvent yi-chloroform), uhlalutyo oluzimeleyo lwe-alcohol, i-ester kunye ne-ketone, njl.
