Pazasi pane pfupi sumo yechiitiko, mhando pamwe nekuongororwa kwakarongeka kwezvikamu zvakasiyana siyana zvekuchengetedza
1.Maitiro ese ekuitaanochengetedza
Kuchengetedza kune maGransly emakemikari anobatsira kuuraya kana kudzivirira zviitiko zvehutachiona mune cosmetics ecosetsics pamwe nekuchengetedza huwandu hwemazwi emazwi pane imwe nguva yakareba.
Nekudaro, zvinofanirwa kucherechedzwa kuti kuchengetedza hakusi kuraswa
Preservatives Inhibit microbial kukura ichivharira synthesis yeakakosha metabolic enzymes pamwe nekunyadzisa synthesis yemapuroteni mune yakakosha cell zvikamu kana synthesis yemu acid.
2.Zvinhu zvinokanganisa zviitiko zvezvivakwa
Zvinhu zvakawanda zvinopa mhedzisiro yezvekuchengetedza. Zvinosanganisira;
a.Mhedzisiro yePH
Shanduko muPH inopa mukuparadzaniswa kweiyo organic acid inochengetedza, uye nekudaro inokanganisa kushanda kwese kwekuchengetedza. Tora semuenzaniso, pH 4 uye Ph 6, 2-Bromo-2-Nitro-1,3-Propandioli yakagadzikana kwazvo
b.Mhedzisiro yeGel uye yakasimba zvidimbu
Koalin, Magnesium Silcate, Aluminium etc, ndeimwe powder zvikamu zvevanovapo mune mamwe macometics, ayo anowanzo kutora kuchengetedza uye kutungamira pakurasikirwa kwechiitiko neinochengetedza. Nekudaro, vamwe vanoshandawo mukubvisa mabhakitiriya ari parizvino mune yekuchengetedza. Zvakare, musanganiswa wePoluble Polymer Gel uye Chengetedza zvinobatsira pakudzikisira mukudzikisira kwekusangana kwekuchengetedza nguva yekuchengetedza, uye izvi zvakaderedzawo mhedzisiro yekuchengetedza.
c.Solubilization mhedzisiro yevasirioni surfacts
Iyo solubilization ye akasiyana-siyana surfacers dzakadai sevanhu vasingachengetedzi vechikoro vanokanganisawo chiitiko chakawanda chekuchengetedza. Nekudaro, shuwa yemafuta isingasviki yeHLB = 3-6 inozivikanwa kuve neyakawedzera gadziriro inogona kuenzanisa pane inokonzeresa kwemvura isingasviki surfact
d.Mhedzisiro yePreservative Kuwedzeredza
Pane zvimwe zvinhu zvakadai sekupisa, mwenje nezvimwe, izvo zvine basa rekukonzera kudzikira kwekuchengetedza, nekudaro kukonzera kuderedzwa kwemabasa avo antiseptic. Zvizhinji kudaro, zvimwe zvezvipikiso izvi zvinotungamira kune biochemical maitiro semhedzisiro yeradiation sterilization uye nekuwarira.
e.Mamwe mabasa
Saizvozvo, zvimwe zvinhu zvakadai sekuvapo kwekurembera uye kutapurirwa nevamiririri vekuchengetedza mumvura-miviri-chikamu cheshuwa chichaitawo mukudzikiswa kwechiitiko chekuchengetedza kune imwezve.
3.Iyo Antiseptic Properties yeZvivakwa
Iyo Antiseptic Properties yeZvekudzivirira inokodzera kufunga nezvayo. Kuve nekunyanyisa kuchengetedza mune cosmetic hakuiti kunotsamwisa, nepo kuperevedza mukusangana kuchakanganisa antisepticzvivakwa zvezvivakwa. Nzira yakanakisa yekuongorora izvi iri kushandisa iyo biological priness bvunzo iyo inosanganisira iyo shoma inhibitory yekushambadzira (mic) uye iyo inhibition zone bvunzo
Bacterictic Circle Test: Iyi bvunzo inoshandiswa kuona idzo mabhakitiriya uye mold nekukwanisa kukura nekukurumidza mushure mekurima svutugadzike. Mumamiriro ezvinhu apo pepa refaira rakamisikidzwa neyekuchengetedza rakadonhedzwa nepakati peiyo yetsika yepakati mundima yepakati, pachave nedenderedzwa rechitenderedzwa rakaumbwa rakatenderedza nekuda kwekuparadza. Paunenge uchiyera dhivhiri rezvikamu zvehutachiona, zvinogona kushandiswa seyadyntick kuti uone inoshanda yeinochengetedza.
Naizvozvi, zvinogona kutaurwa kuti denderedzwa rehutachiona uchishandisa iyo Pepa nzira ine diameter> = 1.0mm inoshanda kwazvo. Mic inoendeswa kuSeass yekuvharidzira yeChengetedzo iyo inogona kuwedzerwa mune yepakati kuti isatibit microbial kukura. Mumamiriro ezvinhu akadaro, mikara madiki, iyo yakasimba iyo artimicrobial zvivakwa zvechengetedzo.
Simba kana mhedzisiro yeAnimicrobial chiitiko chinowanzotaura nenzira yeiyo shoma inhibitory yekushambadzira (Mic). Nekuita izvi, chiitiko chakasimba cheantimicrobial chiitiko chinotemerwa nekukosha kwechidiki cheMic. Kunyangwe iyo mic haigoni kushandiswa kusiyanisa pakati peBuctididal uye bacticidal chiitiko, surfers
Sezvineiwo, panguva dzakasiyana, zviitiko zviviri izvi zvinoitika panguva imwe chete, uye izvi zvinoita kuti zviome kusiyaniswa. Nechikonzero ichi, vanowanzo kupihwa zita rakaunganidzwa sekurewisirwa kweAntimicrobial kana kungova nehanya.
