SORBITAN STEARATE (Siv 60)

Span 60, uas yog, sorbitan monostearate (SorbitanMonostearate, Span60), tseem hu ua sorbitan monostearate, sorbitan stearate ester. Cov mis mos molecular: C24H46O6. Nrog ib tug txheeb ze molecular loj ntawm 430.62, nws yog ib tug waxy khoom xws li lub teeb milky dawb mus rau brownish - daj, thiab tshwm nyob rau hauv daim ntawv ntawm flakes los yog blocks. Nws muaj ib tug me ntsis stench tab sis ib tug me ntsis saj. Qhov chaw khov kho: 50-52℃. Nws yog insoluble nyob rau hauv dej txias thiab acetone, tab sis yuav dispersed nyob rau hauv dej kub thiab benzene. Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol, ether, methanol, aniline thiab carbon tetrachloride. Nws yog soluble hauv cov roj ntxhia thiab ethyl acetate saum 50 degree. Nws ruaj khov nyob rau hauv cov kev daws teeb meem ntawm PH qhov sib txawv ntawm chav tsev kub, nrog rau HLB tus nqi ntawm 4.7. Sorbitol monostearate yog ib qho zoo tshaj plaws ntaus foaming neeg sawv cev los yog aerating tus neeg sawv cev thaum siv ib leeg nyob rau hauv daim ntawv muab tshuaj txhuam los yog ua ke nrog lwm yam emulsifiers, tshwj xeeb tshaj yog cov uas muaj ib tug -crystalline nyiam. Sorbitol monostearate yog lipophilic emulsifier uas tuaj yeem siv los npaj W / O emulsions. Nws lub zog emulsifying yog superior rau lwm cov emulsifiers, tab sis nws cov tsw tsis zoo, yog li nws feem ntau yog siv ua ke nrog lwm cov emulsifiers.
