I-emulsifier ehamba phambili ye-Unipromai-potassium cetyl phosphateibonise ukusebenza okuphezulu kakhulu ekwakhiweni okusha kokuvikela ilanga uma kuqhathaniswa nobuchwepheshe obufanayo be-potassium cetyl phosphate emulsification. Ukuguquguquka kwayo kanye nokuhambisana kwayo okubanzi kwenza kube lula ukuhlanganiswa kokuvikela ilanga emikhiqizweni yokunakekelwa kwesikhumba kanye nezimonyo enikeza izinzuzo ezengeziwe, ukuvikelwa okuphelele kanye nokuthungwa okukhangayo okufunwa ngabathengi emhlabeni wonke.
Ukuvikelwa kwelanga okwanele akugcini nje ngokuvimbela ukuguga kwesikhumba ngaphambi kwesikhathi kanye nemigqa emincane nemibimbi ehambisana nakho: futhi kunikeza isivikelo esibalulekile emisebeni ye-UV engaholela kumdlavuza wesikhumba. Ngokujabulisayo, izihlungi ze-UV zanamuhla zinamandla okuvikela ngisho nesikhumba esizwela kakhulu emazingeni aphezulu emisebeni ye-UV. Kodwa-ke ucwaningo lwembula ukuthi abantu bayanqikaza ukufaka i-sunscreen kaningi ngokwanele futhi ngobuningi obanele ukuqinisekisa isivikelo esifanele.
Izinkolelo, ukuziphatha kanye nezidingo

Ngakho-ke kusobala ukuthi kunesidingo sezinhlelo zokusebenza ezintsha zokuvikela ilanga ezihambisana nemithi yokuvikela ilanga evamile futhi ezingafakwa kalula nangokuphumelelayo empilweni yabantu yansuku zonke kanye nemikhuba yokunakekelwa komuntu siqu. Isidingo esikhulayo semikhiqizo yokunakekela ilanga ebusweni esebenza ngezikhathi eziningi njengokhilimu wezinhlamvu, ikakhulukazi, siletha izinselele ezintsha - ngakho-ke amathuba - kwabakhi.
Kulesi simo, ukukhanga kwemizwa kwemikhiqizo yokunakekelwa komuntu siqu manje kuhambisana nokusebenza kahle komkhiqizo njengomshayeli wezinqumo obaluleke kakhulu.
Ama-Emulsifier: isithako esiyinhloko ekusebenzeni nasekuqondeni imizwa

Isithako sokugcina sibaluleke kakhulu, ngoba ukwandisa okuqukethwe kotshwala kwefomula kunikeza ukuthungwa okulula futhi kunikeza umuzwa wesikhumba oqabulayo.
Ikhono lokwandisa ukugcwala kotshwala liphinde linikeze abakhiqizi ithuba lokuguquguquka okukhulu ekukhetheni kwabo uhlelo lokulondoloza i-emulsion, noma kungaqeda nesidingo salo.
Isakhiwo seI-Smartsurfa-CPKNjenge-phosphonolipide {lecithin kanye ne-cephaline) esikhumbeni, inobuhlobo obuhle kakhulu, iphephile kakhulu, futhi ikhululekile esikhumbeni, ngakho-ke ingasetshenziswa ngokuphephile emikhiqizweni yokunakekela izingane.
Imikhiqizo ekhiqizwe ngesisekelo se-Smartsurfa-CPK ingakha ungqimba lwe-membrane engangeni manzi njengosilika ebusweni besikhumba, inganikeza ukumelana kwamanzi okusebenzayo, futhi ifaneleka kakhulu ku-sunscreen ehlala isikhathi eside kanye nesisekelo; Nakuba ine-SPF ehambisanayo ecacile ye-sunscreen.
