nkhani

Pamene zofuna za ogula zokhudzana ndi chitetezo cha khungu zikukwera, "kuyeretsa pang'ono + kukonza zotchinga" kwakhala njira yofunika kwambiri yowunikira zotsukira nkhope.Sodium cocoyl glutamate(CAS 68187-32-6), chinthu chachilengedwe cha amino acid chomwe chimachokera ku mafuta a kokonati ndi glutamic acid, chimafupikitsidwa kuti SCG. Chifukwa cha kukwiya kochepa komanso kugwirizana kwambiri, chikukhala chinthu chofunikira kwambiri cha mitundu yayikulu yokongola, zomwe zikuyendetsa msika wa amino acid wosamalira khungu kukhala gawo lotukuka bwino.

I. Ubwino waukulu umaonekera: kupita patsogolo kwa kufatsa ndi kugwira ntchito bwino

Kukwera kwasodium cocoyl glutamate surfactantZimachokera ku luso lake lapamwamba la zosakaniza zoyeretsera zachikhalidwe. Monga anionic amino acid surfactant, scg sodium cocoyl glutamate imakwaniritsa bwino mphamvu yoyeretsera ndi kufatsa kudzera mu kapangidwe kake kapadera ka molekyulu - sodium cocoyl glutamate sikuti imangosungunula mafuta ndi dothi pakhungu mwachangu, ndikupanga thovu lolimba komanso losavuta kutsuka, komanso imachepetsa kuwonongeka kwa mafuta mu stratum corneum. Kuchuluka kwa kuwonongeka kwa stratum corneum ndi kotsika ndi 68% kuposa kwa ma surfactants achikhalidwe okhala ndi sulfate.

pH ya chinthu ichi ndi yokhazikika pakati pa 5.0 mpaka 6.0, zomwe zimagwirizana kwambiri ndi pH ya filimu ya sebum ya khungu labwino. Imatha kupewa kuwonongeka kwa chotchinga cha khungu panthawi yoyeretsa. Mayesero a anthu atsimikizira kuti mutagwiritsa ntchito zinthu zomwe zili ndi chinthuchi, kutaya madzi kwa transepidermal (TEWL) pakhungu kumakhala kotsika ndi 42% kuposa kwa zotsukira nkhope zachikhalidwe. Pakadali pano, kuchuluka kwake kochepa kwambiri (kuchuluka kwa zomwe zimachitika pa mayeso a HRIPT ndi 0.3%) komanso kuchuluka kwa kuyamwa kwa percutaneous kosakwana 0.01% kumapangitsa kuti zikhale zotetezeka kwa magulu apadera monga khungu lofewa, amayi apakati ndi makanda kugwiritsa ntchito.

II. Sodium cocoyl glutamate imapezeka m'mitundu yosiyanasiyana: kuyambira pa zinthu zazikulu mpaka zapamwamba.

Pakadali pano, disodium sodium cocoyl glutamate yakhala chinthu chofunikira kwambiri pakuyeretsa khungu monga zotsukira nkhope, zotsukira thupi ndi shampu, ndi mapangidwe kuyambira zinthu zotsika mtengo zapakhomo mpaka zopangidwa zapamwamba zapadziko lonse lapansi. Zonsezi zimaitenga ngati chinthu chachikulu chopangira zinthu, kuphatikiza ndi zosakaniza zokonzanso monga ceramide ndi panthenol, zomwe zimakwaniritsa zosowa zoyeretsa khungu louma komanso lofewa komanso khungu lowonongeka ndi zotchinga zowonongeka.

Mu gawo la zotsukira nkhope zogwira ntchito, kugwiritsa ntchito mankhwala osakaniza awa kwapangitsa kuti zinthu zisinthe kwambiri. Zinthu zina, kudzera mu mgwirizano wa ma amino acid surfactants ena monga potassium cocoyl glycinate, kuphatikiza ndi niacinamide, tiyi extract ndi zosakaniza zina, zimapanga njira yogwiritsira ntchito "kuyeretsa + kulamulira mafuta + kuletsa ukalamba". Deta yogwiritsidwa ntchito masiku 28 ikuwonetsa kuti zinthu zotere zimatha kuchepetsa kutulutsa mafuta pakhungu lamafuta ndi 42% ndikuchepetsa kufiira pakhungu losavuta ndi 90%. Deta yoyesera yachitatu ikuwonetsa kuti zotsukira nkhope zapamwamba kwambiri zomwe zili ndi mankhwalawa zimatha kuchotsa 97% ya SPF50 + chitetezo cha dzuwa ndi zodzoladzola za tsiku ndi tsiku, kukwaniritsa zosowa za anthu oyenda pa "kutsuka ndi kuchotsa mu imodzi".

III. Kodi sodium cocoyl glutamate ndi yotetezeka?

Kukwiya kochepa

Mayeso oyesa kuyabwa kwa maso (OECD 405 standard): Sodium cocoyl glutamate sikuwonetsa kuyabwa (score < 1), zomwe ndi zabwino kuposa zigawo zachikhalidwe za sulfate (monga SLS/SLES);

Kuyesa kwa khungu (HRIPT): Kuchuluka kwa sensitization ndi 0.3% yokha. Disodium sodium cocoyl glutamate ndi yotsika kwambiri kuposa kuchuluka kwa sensitization yapakati ya zinthu zopangira zodzikongoletsera (2.1%), ndipo ingagwiritsidwe ntchito mosamala ndi azimayi okalamba komanso apakati.

Yofewa komanso yoyenera khungu

pH imakhazikika pa 5.0-6.0, zomwe zimagwirizana kwambiri ndi pH ya sebum film ya khungu labwino (4.5-6.5), kupewa kuuma ndi kulimba kwa khungu pambuyo poyeretsa.

Sodium cocoyl glutamate siiwononga kapangidwe ka mafuta a stratum corneum. Pambuyo poigwiritsa ntchito, kutayika kwa madzi a transepidermal (TEWL) pakhungu kumachepa ndi 15% mpaka 20%, zomwe zimathandiza kusunga umphumphu wa chotchinga cha khungu.

Chitetezo cha chilengedwe ndi kagayidwe kachakudya

Kuchuluka kwa kuwonongeka kwa zinthu zachilengedwe kuli pamwamba pa 90% (muyezo wa OECD 301B), popanda chiopsezo cha kuipitsidwa kwa madzi, zomwe zikukwaniritsa zofunikira zoteteza chilengedwe.

Thupi la munthu limagwira ntchito mwachangu kwambiri, makamaka kudzera mu mkodzo, ndipo palibe chiopsezo chodziunjikira m'thupi.

IV. Chikhalidwe cha mafakitaleSCG sodium cocoyl glutamate kugulandi zabwino: Kufatsa kwachilengedwe kumakhala chinsinsi chopangira zisankho kwa ogula

Pamene gulu la "gulu la zosakaniza" likukula, zofuna za ogula za chitetezo ndi zachilengedwe za zosakaniza zosamalira khungu zikupitirira kukwera. Zopangira za sodium cocoyl glutamate zimachokera ku zinthu zachilengedwe ndipo zimakhala ndi kuchuluka kwa kuwonongeka kwa biogradation kopitilira 90% mkati mwa masiku 28, zomwe zimagwirizana ndi momwe anthu amagwiritsira ntchito zinthu zosamalira chilengedwe. Kuchuluka kwa zinthu zofananira zomwe zimasaka pa nsanja za e-commerce kumawonjezeka pachaka kopitilira 60%. M'ndandanda zina zogulitsa kwambiri za zotsukira nkhope za amino acid, zinthu zomwe zili ndi zosakanizazi zimakhala ndi zoposa 70%.

Akatswiri a khungu amati kuyeretsa pang'onopang'ono ndiye maziko osungira thanzi la khungu. Sodium cocoyl glutamate surfactant, yokhala ndi ubwino wake wokhala wofatsa komanso wosakwiyitsa komanso woyenera mitundu yonse ya khungu, pang'onopang'ono ikusintha ma surfactants achikhalidwe okwiyitsa ndikukhala chisankho chachikulu cha zinthu zosamalira khungu. M'tsogolomu, ndi kupititsa patsogolo ukadaulo wa formula, kugwiritsidwa ntchito kwake m'njira zapadera monga kukonza zaluso pambuyo pa zamankhwala ndi chisamaliro cha makanda kudzapitirira kukula, kulimbikitsa chitukuko cha malo osamalira khungu ndi kuyeretsa kupita ku njira yotetezeka komanso yolondola.

Ndife akatswiriogulitsa sodium cocoyl glutamateTikupereka zinthu zapamwamba kwambiri za sodium cocoyl glutamate pamtengo wotsika wa sodium cocoyl glutamate—takulandirani kuti mugule sodium cocoyl glutamate yosamalira khungu lanu, chisamaliro chanu chaumwini kapena ntchito zamafakitale!
