Awọn ọja Apejuwe
O jẹ omi ti ko ni awọ pẹlu iki ti o duro ati gbigba omi to dara.
O fẹrẹ jẹ alaini oorun, ko ni ina ati majele iṣẹju.Iwọn molikula rẹ jẹ 76.09.Irisi rẹ (20oC), agbara ooru kan pato (20oC) ati ooru wiwaba ti afẹfẹ (101.3kpa) jẹ lẹsẹsẹ 60.5mpa.s, 2.49KJ/(kg. oC) ati 711KJ/kg.
O le dapọ ati yanju pẹlu ọti, omi ati awọn aṣoju Organic orisirisi.
Propylene Glycol jẹ ohun elo aise fun murasilẹ resini polyester ti ko ni irẹwẹsi, plasticizer, oluranlowo ti nṣiṣe lọwọ dada, aṣoju emulsifying ati oluranlowo demulsifying.
O tun le ṣee lo bi oludena mimu, apakokoro fun eso, oludena yinyin ati oluranlowo itọju ọrinrin fun taba.
