Parizvino, ma surfactants haashandiswi mumishonga yekuuraya zvipembenene chete asiwo mumishonga yese yekuuraya zvipembenene. Muna 1993, kushandiswa kwe surfactants pasi rose kwemishonga yekuuraya zvipembenene kwaive matani angangoita 230,000, zvichireva 3.3% yekushandiswa kwese kwe surfactants. MuUnited States, mutengo wekutengesa we surfactants yemishonga yekuuraya zvipembenene waive 6% yemusika wayo wemishonga yekuuraya zvipembenene. Hafu yemishonga yese yekuuraya zvipembenene muna 1992 yaishandisa ma surfactants, mazhinji acho aishandiswa mumishonga yekuuraya zvipembenene. MuChina, kushandiswa kwe surfactants yemishonga yekuuraya zvipembenene kwaive matani angangoita 40,000, uye chikamu chimwe muzvitatu chichishanda se emulsifiers.
Mishonga inouraya utachiona inogona kushandura mishonga yezvipembenene isingatarisirwi kuita mishonga yekuuraya utachiona inoshanda. Semubatsiri wemishonga yekuuraya utachiona, haingobatsiri chete pakushandisa mishonga yekuuraya utachiona asiwo inoderedza mwero wemishonga yekuuraya utachiona, inoderedza kukanganisa kwemishonga yekuuraya utachiona munharaunda, uye inopa mabhenefiti makuru mukugadzirwa kwekurima. Zvisinei, sezvo mishonga yekuuraya utachiona iri makemikari akakosha ane basa rakasimba rezvehupenyu, uye zvinangwa zvavo zvekudzora, zvinhu zvakachengetedzwa, uye mamiriro ezvakatipoteredza akaomarara, mishonga yekuuraya utachiona inofanira kusarudzwa uye kugadzirwa zvichienderana nehunhu uye hunhu hwezvinhu zvehunyanzvi, ukuwo ichitarisawo mhedzisiro yemishonga yacho pazvisikwa zvinovavarirwa.
Zvinotevera zvinotarisa pakuunza nhungamiro dzekushandiswa kwemhando nhatu dzemasurfactants.
Nekushandisa micellar action yemasurfactants, kunyungudika kwezvinhu zvehunyanzvi zvisina kunyungudika muzvinonyungudutsa kunowedzera zvakanyanya, izvo zvinozivikanwa sekunyungudika. Masurfactants ane HLB kukosha kwe15–18 inogona kushanda sezvinhu zvinonyungudutsa, asi kunyungudutsa kunoitika chete kana huwandu hwechinhu chinonyungudutsa hunonyanya kukosha hwe micelle. Panguva ino, mushonga usinganyunguduke zvakanaka unovharirwa kana kunyungudutswa mukati me micelles nemapoka e lipophilic echinhu chinonyungudutsa, nepo mapoka e hydrophilic echinhu chinonyungudutsa mvura achiramba ari mumvura, zvichiita kuti mishonga isiri ye polar inyunguduke mumvura.
Zvinoparadzira zvinogona kukanganisa kana kudzivirira kuungana kwezvikamu zvakasimba kana zvemvura muhurongwa hwekupararira uye kuchengetedza kupararira kwazvo kwakafanana kwenguva yakareba. Zvinoparadzira zvinonamira panzvimbo inopindirana nemvura yemafuta kana pamusoro pezvikamu zvakasimba, zvichigadzira chivharo chemagetsi kana steric inhibitory potential barrier chakakomberedza zvikamu, izvo zvinobatsira kudzivirira zvikamu zvezvipembenene kuti zvisaunganezve panguva yekugadzira nekuchengetedza. Zvinoparadzira zvinoshandiswa zvinowanzo kuve anionic surfactants dzine rings dzakawanda, dzakadai se sodium salts yealkylnaphthalene sulfonates, naphthalene sulfonic acid-formaldehyde condensates, uye lignosulfonates. Kusiyana neizvi, zvinoparadzira polymeric (senge sodium polycarboxylate) zvakakosha zvikuru mukugadzirira aqueous suspensions nekuda kwehunhu hwazvo hwekunamira, pamwe nekukwanisa kwadzo kuchaja zvikamu zvakapararira uye kugadzira steric potential barrier yakakura.
Mafomula akasanganiswa anozivikanwa nevashandisi nekuda kwekureruka kwawo uye kugona kwawo kuona kuti zvinhu zvakasiyana-siyana zvinouraya zvipembenene zvinopihwa mushonga, ukuwo achidzivirira kusawirirana kunowanzoonekwa mukusanganiswa kwematangi. Mafomula akadaro akagadzirwa ne suspension-based mixed dispersions akagadzirwa achishandisa mushonga wezvipembenene usinganyungudike mumvura uye mushonga wezvipembenene usinganyungudike mumvura une mvura senzira uye ma surfactants seanobatsira, uye anogona kuonekwa semusanganiswa we SC ne EW. Ma surfactants anoshandiswa kazhinji anosanganisira emulsifiers, dispersants, thickeners, nezvimwe. Rudzi urwu rwemushonga harungotambudziki nekudonha kwezvikamu uye madonhwe emafuta ari mu SC ne EW formulations chete, asiwo zvinoita kuti zvive zvakakosha kuita bvunzo dzakasiyana-siyana dzekuchengetedza dzinotonhora nekupisa mumamiriro akasiyana-siyana.
