iindaba

Njengoko iimfuno zabathengi zokuphucula ukhuseleko lokhathalelo lolusu, "ukucoca ngobunono + ukulungiswa kwemiqobo" kuye kwaba yindlela ephambili yokuvavanya izinto zokucoca ubuso.I-sodium cocoyl glutamate(CAS 68187-32-6), i-amino acid surfactant yendalo ephuma kwioyile yekhokhonathi kunye ne-glutamic acid, ifinyeziwe njenge-SCG. Ngenxa yokungavuthi kwayo okuncinci kunye nokuhambelana kwayo okuphezulu, iba sisithako esiphambili sefomyula kwiimveliso ezinkulu zobuhle, iqhuba imakethi yokhathalelo lolusu lwe-amino acid kwinqanaba lophuhliso olucokisekileyo.

I. Inzuzo ephambili iyabonakala: impumelelo ephindwe kabini kubulali nokusebenza kakuhle

Ukunyuka kwei-sodium cocoyl glutamate surfactantivela kubuchule bayo bokuvelisa izithako zokucoca zemveli. Njenge-anionic amino acid surfactant, i-scg sodium cocoyl glutamate ifikelela kwibhalansi phakathi kwamandla okucoca kunye nobuthathaka ngokusebenzisa isakhiwo sayo esikhethekileyo se-molecular - i-sodium cocoyl glutamate ayinakunyibilikisa ioyile kunye nokungcola ngokukhawuleza kumphezulu wesikhumba, yenze i-foam exineneyo nehlambulula ngokulula, kodwa ikwanciphisa umonakalo kwi-lipids kwi-stratum corneum. Izinga layo lomonakalo kwi-stratum corneum liphantsi ngama-68% kunelo le-surfactants zemveli ezisekelwe kwi-sulfate.

Ixabiso le-pH yale nto isetyenzisiweyo lizinzile phakathi kwe-5.0 ukuya kwi-6.0, nto leyo ehambelana kakhulu nexabiso le-pH yefilimu ye-sebum yolusu oluphilileyo. Ingathintela umonakalo kumqobo wolusu ngexesha lenkqubo yokucoca. Izilingo zabantu ziqinisekisile ukuba emva kokusebenzisa iimveliso eziqulethe le nto, ukulahleka kwamanzi e-transepidermal (TEWL) yolusu kuphantsi ngama-42% kunezo zokucoca ubuso zendabuko. Okwangoku, izinga layo lokubonakalisa ulusu liphantsi kakhulu (izinga lokuphendula lovavanyo lwe-HRIPT liyi-0.3% kuphela kwaye izinga lokufunxwa kwesikhumba elingaphantsi kwe-0.01% lenza kube lula kumaqela akhethekileyo afana nolusu olubuthathaka, abafazi abakhulelweyo kunye neentsana ukuba zisetyenziswe.

II. I-sodium cocoyl glutamate ineendlela ezahlukeneyo zokusetyenziswa kwimarike: igubungela zonke iimeko ukusuka kubunzima ukuya kwizinga eliphezulu

Okwangoku, i-disodium sodium cocoyl glutamate iye yaba sisithako esiphambili kwiimveliso zokucoca ulusu ezifana nezicoci zobuso, izihlambi zomzimba kunye neeshampu, kunye noyilo oluvela kwiimveliso zasekhaya ezifikelelekayo ukuya kwiimveliso zamazwe ngamazwe ezikumgangatho ophezulu. Zonke ziyithatha njenge-surfactant eyintloko, idityaniswe nezithako zokulungisa ezifana ne-ceramide kunye ne-panthenol, ihlangabezana ngokuchanekileyo neemfuno zokucoca ulusu olomileyo nolunobuthathaka kunye nezithintelo ezonakeleyo.

Kwicandelo lee-cleaners zobuso ezisebenzayo, ukusetyenziswa kwesi sithako esidibeneyo kufikelele kuphuculo olunemilinganiselo emininzi. Ezinye iimveliso, ngokusebenzisana nezinye ii-amino acid surfactants ezifana ne-potassium cocoyl glycinate, zidityaniswe ne-niacinamide, i-tea extract kunye nezinye izithako, zenza ifomula enemisebenzi emininzi "yokucoca + ulawulo lweoyile + ukulwa nokwaluphala". Idatha yokusetyenziswa kweentsuku ezingama-28 ibonisa ukuba ezi mveliso zinokunciphisa ukukhutshwa kweoyile kulusu olunamafutha ngama-42% kwaye zinciphise ukuvela kokubomvu kulusu olubuthathaka ngama-90%. Idatha yovavanyo lomntu wesithathu ibonisa ukuba ii-cleaners zobuso ezisemgangathweni ophezulu eziqulethe esi sithako zinokususa ngaphezulu kwama-97% e-SPF50 + ukhuseleko lwelanga kunye nokuthambisa ukukhanya kwemihla ngemihla, ukuhlangabezana neemfuno ezilula zabantu abahamba ngeenyawo "zokuhlamba nokususa kwisinye".

III. Ingaba i-sodium cocoyl glutamate ikhuselekile?

Ukucaphuka okuphantsi

Uvavanyo lokucaphuka kwamehlo (umgangatho we-OECD 405): I-sodium cocoyl glutamate ayibonisi mpendulo icaphukisayo (amanqaku < 1), nto leyo ingcono kuneenxalenye ze-sulfate zemveli (ezifana ne-SLS/SLES);

Uvavanyo lokubonakalisa ulusu (HRIPT): Izinga lokubonakalisa ulusu liyi-0.3% kuphela. I-disodium sodium cocoyl glutamate iphantsi kakhulu kunezinga lokubonakalisa ulusu oluqhelekileyo lwezinto ezikrwada zobuhle (2.1%), kwaye ingasetyenziswa ngokukhuselekileyo lusu olubuthathaka kunye nabasetyhini abakhulelweyo.

Ithambile kwaye ifanelekile kwisithintelo solusu

Ixabiso le-pH lizinzile kwi-5.0-6.0, nto leyo ehambelana kakhulu nexabiso le-pH yefilimu ye-sebum yolusu olusempilweni (4.5-6.5), nto leyo ethintela ukoma kunye nokuqina kolusu emva kokuhlanjululwa.

I-sodium cocoyl glutamate ayonakalisi isakhiwo se-lipid se-stratum corneum. Emva kokusetyenziswa, ukulahleka kwamanzi e-transepidermal (TEWL) kolusu kuncipha nge-15% ukuya kwi-20%, nto leyo enceda ukugcina ukuthembeka komqobo wolusu.

Ukhuseleko kwindalo esingqongileyo kunye nemetabolism

Izinga lokubola kwezinto eziphilayo lingaphezulu kwe-90% (umgangatho we-OECD 301B), ngaphandle komngcipheko wongcoliseko lwamanzi, ohlangabezana neemfuno zokhuseleko lokusingqongileyo.

Umzimba womntu unemetabolism ekhawulezayo, ikakhulu ephuma ngomchamo, kwaye akukho mngcipheko wokuqokelelana emzimbeni.

IV. Indlela eqhuba ngayo ishishiniThenga i-SCG sodium cocoyl glutamateilungile: Ubulali bendalo buba ngundoqo ekwenzeni izigqibo zomthengi

Njengoko iqela "leqela lezithako" likhula, iimfuno zabathengi zokhuseleko kunye nobume bendalo bezithako zemveliso yokhathalelo lolusu ziyaqhubeka nokunyuka. Izinto eziluhlaza ze-sodium cocoyl glutamate zithathwe kwizinto eziluhlaza zendalo kwaye zinezinga lokubola kwe-bio elingaphezulu kwe-90% kwiintsuku ezingama-28, elihambelana nomkhwa wokusetyenziswa okunobuhlobo nokusingqongileyo. Umthamo wokukhangela weemveliso ezinxulumene nazo kumaqonga e-e-commerce unezinga lokukhula konyaka elingaphezulu kwe-60%. Kwezinye uluhlu lwezicoci zobuso ze-amino acid ezithengiswa kakhulu, iimveliso eziqulethe esi sithako zingaphezulu kwe-70%.

Iingcali zesikhumba zithi ukucoca ngobunono sisiseko sokugcina impilo yolusu. I-sodium cocoyl glutamate surfactant, kunye neenzuzo zayo zokuba mnene kwaye ayicaphukisi kwaye ifanelekile kuzo zonke iintlobo zolusu, ithatha indawo ye-surfactants zemveli ezicaphukisayo kwaye iba lukhetho oluphambili kwiimveliso zokucoca ulusu. Kwixesha elizayo, ngokuphuculwa ngakumbi kwetekhnoloji yefomula, ukusetyenziswa kwayo kwiimeko ezikhethekileyo ezifana nokulungiswa kobugcisa emva kwezonyango kunye nokunakekelwa kweentsana kuya kuqhubeka nokukhula, kukhuthaza uphuhliso lwentsimi yokhathalelo lolusu kunye nokucoca ukuya kwicala elikhuselekileyo nelichanekileyo.

Singabantu abaziingcaliabathengisi be-sodium cocoyl glutamateSinikezela ngezinto ezisemgangathweni ophezulu ze-sodium cocoyl glutamate ezithengiswa ngobuninzi ngexabiso eliphantsi le-sodium cocoyl glutamate—wamkelekile ukuqhagamshelana nathi ukuze uthenge i-sodium cocoyl glutamate yokhathalelo lwakho lolusu, ukhathalelo lomntu okanye ukusetyenziswa kwemizi-mveliso!
