I-emulsifier ehamba phambili ye-Unipromai-potassium cetyl phosphateibonise ukusebenza okugqwesileyo kwimixube yokhuselo lwelanga olunoveli xa kuthelekiswa nobuchwepheshe obufanayo be-potassium cetyl phosphate emulsification. Ukuguquguquka kwayo kunye nokuhambelana okubanzi kwenza ukuhlanganiswa kokukhuselwa kwelanga ekunyamekelweni kwesikhumba kunye neemveliso zokuthambisa ezinikezela ngeenzuzo ezongezelelweyo, ukukhuselwa kokugqibela kunye neempawu ezikhangayo ezifunwa ngabathengi emhlabeni wonke.
Ukukhuselwa elangeni okwaneleyo akuthinteli kuphela ukuguga kolusu kwangaphambi kwexesha kunye nemigca emihle ehambelanayo kunye nemibimbi: ikwabonelela ngokhuseleko olubalulekileyo kwimitha ye-UV enokukhokelela kumhlaza wolusu.

Ngoko ke kukho ngokucacileyo imfuneko yezicelo ezintsha zokukhusela ilanga ezihambelana nezithambisi zelanga eziqhelekileyo kwaye zinokudityaniswa ngokulula nangokufanelekileyo kubomi bemihla ngemihla babantu kunye neenkqubo zokunyamekela umntu. Imfuno ekhulayo yeemveliso zokhathalelo lwelanga lobuso ezininzi ezifana neekhrimu zealfabhethi, ngakumbi, ivelisa imingeni emitsha - kwaye ke ngoko amathuba - kubaqulunqi.
Kulo mxholo isibheno sovakalelo seemveliso zokhathalelo lomntu ngoku zihambelana nokusebenza kwemveliso njengomqhubi wesigqibo esibaluleke kakhulu.
I-Emulsifiers: isithako esiphambili ekusebenzeni kunye nokuqonda kwengqondo
