I. Ukusuka kwiikhemikhali eziqatha ukuya ekusebenzeni kakuhle: Ukunyuka kweeTaurates kuNyango loMntu

Ishishini lokunyamekela abantu litshintsha kakhulu. Abathengi bafunde kakhulu kunangaphambili, behlola uluhlu lwezithako ze-sulfates, i-parabens, kunye neesepha eziqinileyo. Olu tshintsho luye lwabangela imfuno yezinto zokucoca ezithambileyo, ezihlala ixesha elide, kodwa ezisebenzayo kakhulu. Eyona nto iphambili kule ntshukumo kukubaI-Sodium Methyl Cocoyl Taurate (SMCT), i-surfactant esekelwe kwi-amino acid esiya iba ngumgangatho ophambili weefomyula zeprimiyamu ngokukhawuleza.

Ivela kwi-asidi ze-coconut fatty zendalo kunye ne-amino acid derivative N-methyltaurine, i-SMCT imele umahluko kwi-surfactants zemveli ezifana neSodium Lauryl Sulfate (SLS). Inika isisombululo esinobuchule kwi-formulators ezifuna ukulinganisela ukucoca okunamandla kunye nokuhambelana okugqwesileyo kolusu kunye neenwele. Ulwakhiwo lwayo olukhethekileyo lweemolekyuli, olune-hydrophilic amino acid headgroup, lunegalelo ekuthambekeni kwayo nasekuzinzeni, okwenza ukuba ibe sisithako esinokusetyenziswa ngeendlela ezahlukeneyo kuluhlu olubanzi lwe-pH.

Ngomlinganiselo we-Book index we-8, le khompawundi iyaziwa ngeprofayili yayo yokhuseleko oluphezulu kunye nokubola kwayo, ihambelana nokukhethwa kwabathengi okukhulayo kweemveliso zobuhle "eziluhlaza" kunye "ezicocekileyo". Eli nqaku liphonononga iingenelo ezininzi zeI-Sodium Methyl Cocoyl Tauratekwaye kutheni kufanele kube yintsika yesizukulwana sakho esilandelayo seemveliso zokhathalelo lomntu.

II. Ubumnene obungaguquguqukiyo kunye nokuhambelana kolusu

Enye yezona zinto zibalulekileyoI-Sodium Methyl Cocoyl Tauratebubumnene bayo obumangalisayo. Ngokungafaniyo neesulfates ezirhabaxa ezinokususa iioyile zayo zendalo eluswini kwaye ziphazamise umqobo womswakama,I-SMCTInika amava okucoca athambileyo ngokumangalisayo. Iqela le-"cocoyl", elivela kwioyile yekhokhonathi, lidibene nesakhiwo se-taurate (i-amino acid), linika le surfactant amandla aphezulu kulusu neenwele, nto leyo enciphisa amathuba okucaphuka.

Idatha yobuchwephesha iyaqinisekisa le phrofayili iphantsi yokucaphuka. Izifundo zibonisa ukuba i-SMCT inomlinganiselo ophezulu wetyhefu (LD50 > 2000mg/kg kwiimpuku), kwaye yaziwa ngokuba ithambile kakhulu kune-SLS. Enyanisweni, icetyiswa rhoqo kwiifomyula ezijolise kulusu olubuthathaka, kuquka iimveliso zosana kunye nezicoci zobuso, apho ihlambulula ngempumelelo ngaphandle kokubangela ubomvu okanye ukoma. Ikwanakho nokunciphisa iziphumo ezicaphukisayo zezinye ii-surfactants eziqatha kwifomyula, nto leyo ephucula amava abathengi ngokubanzi.

III. Amava angcono kakhulu okuGxobhoza kunye nokuVavanya imvakalelo

Kwihlabathi lokucoca, igwebu libaluleke kakhulu kwindlela umthengi aqonda ngayo ukusebenza kakuhle.I-Sodium Methyl Cocoyl TaurateIgqwesile kweli candelo, ivelisa igwebu elityebileyo, elikhrim, nelinobunewunewu elifana nokusebenza kwe-sulfates efana ne-SLES. Olu phawu lubalulekile kwiimveliso ezifana neeshampu, izihlambi zomzimba, kunye nezihlambi zobuso, apho igwebu eliqinileyo nelizinzileyo lingancedi nje ekucoceni kodwa likwadala amava amnandi okuziva.

Igwebu eliveliswa yi-SMCT liyaziwa ngokuzinza kwalo, lixhathisa ukuwohloka ngokukhawuleza nokuba kukho amanzi aqinileyo. Olu gwebu lusebenza kakuhle, kunye nobumnene balo, luvumela abenzi bemveliso ukuba benze iimveliso "ezingenasulfate" ezingayithobeliyo igwebu—umngeni oqhelekileyo kwicandelo lobuhle obuluhlaza. Ngaphezu koko, i-SMCT yaziwa ngeempawu zayo zokususa ngokulula. Ayishiyi intsalela enzima, enamathelayo, okanye "ekrwitshayo" eluswini okanye ezinweleni, endaweni yoko inika uvakalelo oluthambileyo, olugudileyo, nolumanzi. Olu ncedo lweemvakalelo luphawu oluphambili kwimarike yokhathalelo lomntu olukhuphisanayo.

IV. Ukuguquguquka kweFomulation ebanzi kunye nozinzo

Kwifomula,I-Sodium Methyl Cocoyl Taurateyindlu enamandla yokuguquguquka. Ibonisa ukuhambelana okuhle kakhulu nezinye iintlobo ezahlukeneyo ze-surfactant, kuquka i-anionic, i-nonionic, kunye ne-amphoteric, inika ii-formulators inkululeko yokwenza imixube enzima, edibeneyo. Oku kuhambelana kubalulekile ekulungiseni i-viscosity, ubume, kunye nokusebenza ngokubanzi.

Ngaphezu koko, i-SMCT izinzile kakhulu kuluhlu olubanzi lwe-pH, ngesiqhelo ukusuka kwi-pH 3 ukuya kwi-11. Olu zinzo luyenza ifaneleke kwiimveliso ezahlukeneyo, ukusuka kwizicoci ezikhupha i-asidi ukuya kwiifomyula ezingathathi cala okanye ezithambileyo ze-alkaline. Amanqanaba aphezulu afana neGeropon® TC Clear MB atshintshe indlela yokuphatha, enika ifomathi yolwelo ezinzileyo, ebanda ecoca lula eyenza kube lula ukwenziwa kwaye isuse isidingo sokufudumeza kwangaphambili okufunekayo kwiifom zendabuko zokuncamathisela. Ezi nguqulelo "zetyuwa ephantsi kakhulu" (<0.5% NaCl) zikwaphucula ukuhambelana neziqinisi ezibuthathaka kwityuwa kunye neepolymers ze-cationic, zithintela ukungazinzi kwefomyula kunye nokuna kwemvula.

V. Uzinzo kunye neProfayili "eLuhlaza"

Umthengi wanamhlanje akakhathali nje kuphela ngento eyenziwa yimveliso kuye, kodwa uxhalabele nempembelelo yayo kwiplanethi.I-Sodium Methyl Cocoyl TaurateIqhayisa ngeprofayili eqinileyo yozinzo. Yenziwe kwimithombo yendalo evuselelekayo—ioyile yekhokhonathi kunye nee-amino acids—kwaye iyabola ngokulula. Oku kuyibeka njengesithako esifanelekileyo kwiibhrendi ezifuna ukunciphisa uphawu lwazo lokusingqongileyo ngaphandle kokunciphisa ukusebenza kwazo. Umgangatho we-"Book index" we-8 ugxininisa ngakumbi ukhuseleko lwayo kunye neziqinisekiso zokusingqongileyo, ukubonelela abathengi ngoluhlu olongezelelweyo lokuthemba ukuthembeka kwemveliso.

Njengoko eli shishini lisiya kude nezithako ezisekelwe kwi-petroleum kunye nezingaboliyo, ukwamkelwa kwezinye iindlela ezikhathalele indalo, ezisebenza kakhulu njenge-SMCT akusiyo nje into eyenzekayo kodwa kuyimfuneko.

VI. Abaqhubi beeMarike kunye neMbono yeSicelo

Ukwanda okuqhubekayo kwemarike yehlabathi yobuhle obucocekileyo kuvula amathuba amaninzi okufaka iziceloI-Sodium Methyl Cocoyl TaurateKwicandelo lokhathalelo lomntwana eliphambili, ubumnene bayo obugqithisileyo buyenza ibe sisithako esibalulekileyo kwiishampu zeentsana kunye nokuhlamba umzimba, ihlangabezana neemfuno ezingqongqo zabazali zokhuseleko. Kwicandelo le-dermocosmetics yolusu olubuthathaka kunye nengcali, isetyenziswa kakhulu kwiimousse zokucoca ubuso kunye nokususa izimonyo, ihambisa ukucoca okunzulu ngelixa igcina ukhuseleko lwesikhumba—umgangatho ovunyiweyo ziingcali zesikhumba.

Kwangaxeshanye, njengoko ingcamango "yokhathalelo lwentloko" iqhubeka nokukhula, iindlela zokulungisa iishampu eziphambili ziya zisuka kwiisulfates zikhetha iinkqubo ze-surfactant ezisekelwe kwi-amino acid.I-SMCT, ngenxa yokwakheka kwayo okugqwesileyo kwefoam kunye namava okuhlamba iinwele okushiya iinwele zicocekile kodwa zingasuswanga, ibe lolona khetho luphezulu kweli candelo lemarike likhulayo. Ukujonga phambili, ubuchwepheshe obudibeneyo obusekelwe kwiI-SMCTKulindeleke ukuba zikhule ngakumbi kwiinkalo zokucoca ubuso, ukuhlamba umzimba, ishampu, kwanezokhathalelo lomlomo, nto leyo eqhuba lonke ishishini lokhathalelo lomntu siqu ukuya kwikamva elithambileyo nelizinzileyo.
