izindaba

Njengoba izidingo zabathengi zokunakekelwa kwesikhumba zithuthuka, "ukuhlanza kancane + ukulungiswa kwezithiyo" sekuyindlela yokuhlola eyinhloko yezihlanzi zobuso.I-sodium cocoyl glutamate(I-CAS 68187-32-6), i-amino acid surfactant yemvelo etholakala ku-oyela kakhukhunathi kanye ne-glutamic acid, ifushaniswa ngokuthi i-SCG. Njengoba inomsindo omncane kanye nokuhambisana kwayo okuphezulu, iba yisithako esiyinhloko sefomula yemikhiqizo emikhulu yobuhle, iqhuba imakethe yokunakekelwa kwesikhumba yama-amino acid ibe yisigaba sokuthuthuka esicwengekile.

I. Inzuzo eyinhloko ivelele: impumelelo ekabili ngobumnene kanye nokusebenza kahle

Ukuvuka kwei-sodium cocoyl glutamate surfactantivela ekusebenzeni kwayo okusha kwezithako zokuhlanza zendabuko. Njenge-anionic amino acid surfactant, i-scg sodium cocoyl glutamate ifinyelela ibhalansi phakathi kwamandla okuhlanza nobumnene ngesakhiwo sayo esiyingqayizivele sama-molecule - i-sodium cocoyl glutamate ayikwazi nje ukuncibilikisa uwoyela nokungcola ebusweni besikhumba ngokushesha, yakha igwebu eliqinile futhi elihlanza kalula, kodwa futhi inciphisa umonakalo kuma-lipids ku-stratum corneum. Izinga layo lomonakalo ku-stratum corneum liphansi ngo-68% kunele-surfactants yendabuko esekelwe ku-sulfate.

Inani le-pH lalesi sithako lizinzile ngaphakathi kwebanga eliphakathi kuka-5.0 no-6.0, elihambisana kakhulu nenani le-pH lefilimu ye-sebum yesikhumba esinempilo. Lingavimbela umonakalo esikhumbeni ngesikhathi senqubo yokuhlanza. Izilingo zabantu ziqinisekisile ukuthi ngemva kokusebenzisa imikhiqizo equkethe lesi sithako, ukulahlekelwa kwamanzi kwe-transepidermal (TEWL) kwesikhumba kuphansi ngo-42% kunokwezihlanzi zobuso zendabuko. Okwamanje, izinga layo eliphansi kakhulu lokuzwela (izinga lokusabela lokuhlolwa kwe-HRIPT lingu-0.3% kuphela kanye nezinga lokumuncwa kwesikhumba elingaphansi kuka-0.01% kwenza kube kuphephile kumaqembu akhethekile njengesikhumba esibucayi, abesifazane abakhulelwe kanye nezinsana ukusebenzisa.

II. I-sodium cocoyl glutamate inezinhlobo eziningi zezicelo emakethe: ihlanganisa zonke izimo kusukela ku-mass kuya ku-high top

Njengamanje, i-disodium sodium cocoyl glutamate isibe yisithako esiyinhloko ekuhlanzeni imikhiqizo yokunakekelwa kwesikhumba efana nezihlanzi zobuso, izihlanzi zomzimba kanye nama-shampoo, ngezakhiwo kusukela emikhiqizweni yasekhaya engabizi kuya kumikhiqizo yamazwe ngamazwe esezingeni eliphezulu. Bonke bayithatha njenge-surfactant eyinhloko, kuhlanganiswe nezithako zokulungisa ezifana ne-ceramide ne-panthenol, okuhlangabezana nezidingo zokuhlanza zesikhumba esomile nesibucayi kanye nesikhumba esinezithiyo ezonakele.

Emkhakheni wezihlanzi zobuso ezisebenzayo, ukusetshenziswa kwalesi sithako okuhlanganisiwe kufinyelele ukuthuthukiswa okunezilinganiso eziningi. Eminye imikhiqizo, ngokusebenzisana kwamanye ama-surfactants e-amino acid njenge-potassium cocoyl glycinate, kuhlanganiswe ne-niacinamide, i-tea extract nezinye izithako, kudala ifomula enemisebenzi eminingi "yokuhlanza + ukulawula uwoyela + ukulwa nokuguga". Idatha yokusetshenziswa kwezinsuku ezingama-28 ikhombisa ukuthi imikhiqizo enjalo inganciphisa ukukhishwa kwamafutha esikhumbeni esinamafutha ngo-42% futhi yehlise ukwanda kokubomvu esikhumbeni esibucayi ngo-90%. Idatha yokuhlola evela eceleni ikhombisa ukuthi izihlanzi zobuso ezisezingeni eliphezulu eziqukethe lesi sithako zingasusa ngaphezu kuka-97% we-SPF50 + ukuvikelwa elangeni kanye nokukhanya kwansuku zonke, okuhlangabezana nezidingo ezilula zabantu abahamba ngezinyawo "zokugeza nokususa endaweni eyodwa".

III. Ingabe i-sodium cocoyl glutamate iphephile?

Ukucasuka okuphansi

Ukuhlolwa kokucasuka kwamehlo (izinga le-OECD 405): I-sodium cocoyl glutamate ayibonisi ukusabela okucasukayo (isilinganiso < 1), okuyinto engcono kunezingxenye ze-sulfate zendabuko (njenge-SLS/SLES);

Ukuhlolwa kokuzwela kwesikhumba (HRIPT): Izinga lokuzwela lingu-0.3% kuphela. I-disodium sodium cocoyl glutamate iphansi kakhulu kunezinga lokuzwela elijwayelekile lezinto zokusetshenziswa zezimonyo (2.1%), futhi ingasetshenziswa ngokuphephile yizikhumba ezibucayi kanye nabesifazane abakhulelwe.

Ithambile futhi ifanelekela ukuvimbela isikhumba

Inani le-pH lizinzile ku-5.0-6.0, okuhambisana kakhulu nenani le-pH lefilimu ye-sebum yesikhumba esinempilo (4.5-6.5), okugwema ukoma nokuqina kwesikhumba ngemva kokuhlanza.

I-sodium cocoyl glutamate ayilimazi isakhiwo se-lipid se-stratum corneum. Ngemva kokusetshenziswa, ukulahlekelwa kwamanzi kwe-transepidermal (TEWL) kwesikhumba kwehla ngo-15% kuya ku-20%, okusiza ukugcina ubuqotho besivikelo sesikhumba.

Ukuphepha kwemvelo kanye nokusetshenziswa kwe-metabolic

Izinga lokubola kwezinto eziphilayo lingaphezu kuka-90% (izinga le-OECD 301B), ngaphandle kwengozi yokungcoliswa kwamanzi, okuhlangabezana nezidingo zokuvikelwa kwemvelo.

Umzimba womuntu une-metabolism esheshayo, ikakhulukazi ephuma ngomchamo, futhi akukho bungozi bokunqwabelana emzimbeni.

IV. Umkhuba wemboni weI-SCG sodium cocoyl glutamate thengakuyinto enhle: Ubumnene bemvelo buba yisihluthulelo sokwenza izinqumo kumthengi

Njengoba iqembu "leqembu lezithako" likhula, izidingo zabathengi zokuphepha kanye nokuba ngokwemvelo kwezithako zemikhiqizo yokunakekelwa kwesikhumba ziyaqhubeka nokukhula. Izinto zokusetshenziswa ze-sodium cocoyl glutamate zitholakala ezintweni zokusetshenziswa zemvelo futhi zinezinga lokubola kwe-bio elingaphezu kuka-90% zingakapheli izinsuku ezingu-28, okuhambisana nomkhuba wokusetshenziswa okunobungani nemvelo. Inani lokusesha lemikhiqizo ehlobene nalo kumapulatifomu e-e-commerce linezinga lokukhula lonyaka elingaphezu kuka-60%. Kwezinye izinhlu ezithengiswa kakhulu zezihlanzi zobuso ze-amino acid, imikhiqizo equkethe lesi sithako ingaphezu kuka-70%.

Odokotela besikhumba bathi ukuhlanza okuthambile kuyisisekelo sokugcina impilo yesikhumba. I-sodium cocoyl glutamate surfactant, enezinzuzo zayo zokuba mnene futhi ingacasuli futhi ifanele zonke izinhlobo zesikhumba, kancane kancane ithatha indawo yama-surfactants avamile acasulayo futhi iba ukukhetha okujwayelekile kwemikhiqizo yokunakekela isikhumba yokuhlanza. Esikhathini esizayo, ngokuthuthukiswa okwengeziwe kobuchwepheshe befomula, ukusetshenziswa kwayo ezimweni ezikhethekile njengokulungiswa kobuciko ngemuva kwezokwelapha kanye nokunakekelwa kwezinsana kuzoqhubeka nokukhula, kukhuthaze ukuthuthukiswa kwensimu yokunakekelwa kwesikhumba kanye nokuhlanza ibheke endaweni ephephile neqondile.

Singochwephesheabahlinzeki be-sodium cocoyl glutamateenikeza izinto zokusetshenziswa ze-sodium cocoyl glutamate ezisezingeni eliphezulu ngokuthengisa ngobuningi ngentengo encintisanayo ye-sodium cocoyl glutamate—wamukelekile ukuxhumana nathi ukuze uthenge i-sodium cocoyl glutamate yokunakekelwa kwesikhumba sakho, ukunakekelwa komuntu siqu noma ukusetshenziswa kwezimboni!
