Ukongeza, le utywala cetyl isetyenziswa thickener elisemagqabini ishampu, izimiso kunye izimiso iinwele. Njengoko a co-emulsifier lisetyenziswa ekwenziweni arhente depilatory amabhinqa, antiperspirants, zokuthambisa, izithambiso zonke iintlobo iimaski.

Ngenxa iimpawu antiseptecheskih, C16H33OH zisetyenziswa xa kuhlanjwa lotions kunye namanye amajelo eendaba umzimba kunye nesikhumba. Kuyinto ngokupheleleyo amagwebu kwaye yandisa imeko ezinzileyo ugwebu kwiimveliso izithambiso ezinjalo.

inkcazo ngokubanzi izinto

Utywala C16H33OH yale hlobo alukho kurhulumente ngamanzi okanye ijiye. Ngokweliso kufana emhlophe eqina ezityebileyo, njengomthwebeba okanye iparafini ukuba akukho incasa kunye nevumba. Kuyinto ezingenakunyibilika ngamanzi, kodwa lula kwaphela kwaye eqina ngokukhawuleza ezinye ilahleko shape yokuqala. Indlela ukugcina yaye zingabuthisi iipropati ayo ngokupheleleyo naziphi na iimeko.

yokunyibilika nokubilisa kuyo utywala

Cetyl utywala, kwakunye phantse nayiphi na into eqinileyo, kunokuba ithambe. Nangona kunjalo, oku kulula, ekubeni iqondo lokubila le element kwemichiza yi 54,6 ° C. Kuyaphawuleka ukuba C16H33OH njani na ukuze ithumba. Yiloo nto kanye oko idinga ubushushu, ubuncinane ukuya ku-270 okanye ukuya ku 344,0 ° C.

Ziziphi iimpawu luncedo na utywala?

Ingaba kukho naziphi na Izimo ukuba ukusetyenziswa cetyl utywala?

Nangona uluhlu elikhulu iimpawu ezintle, ukusetyenziswa cetyl utshwala ezinye Izimo. Ngokukodwa, akukho mfuneko ukusisebenzisa kwabo bantu abathe baba amacandelo amacandelo utywala isici.
