He aha te Sodium Polyglutamate CAS 28829-38-1?

Kei roto i te natto kai tuku iho te konutai poraka-glutamate. He pūmua anionic waikawa amino piri, ā, e kiia ana ko te waikawa γ-poraka-glutamate. Ko te konutai poraka-glutamate he pūmua koiora polypeptide ōrite me te waikawa glutamic hei wae hanganga, e hanga ana i ngā here amide mā roto i ngā rōpū α-amino me te γ-carboxyl. Nā te mea he maha ngā rōpū hydrophilic kei roto i ia wae hanganga o te waikawa glutamic, ka taea te hanga he maha o ngā here hauwai i roto i te mekameka pūmua, i waenga rānei i ngā ngota, ka pai te mimiti wai me te pupuri makuku o te waikawa poraka-glutamic, ā, ka noho hei wāhanga pupuri makuku tūturu tino pai. Ā, he whānuitia te whakamahinga o te konutai poraka-glutamate i roto i ngā hua tiaki whaiaro.

Tono

Ko te konutai poliglutamate he nui ake te taumaha ngota, ka māeneene te kiri. Ka taea e ia te whakatairanga i te kohikohinga o ngā mea whakamakuku taiao, te whakarei ake i te kaha pupuri wai o te kiri, me te mahi tahi me te HA hei whakapai ake i te ngāwari me te ngawari o te kiri. Nō reira, ka taea te whakamahi whānui i te konutai poliglutamate i roto i ngā momo hua me ngā momo whakapaipai, pērā i ngā kirīmi, ngā hinu kiri, ngā hinu kakara, ngā kopare kanohi, ngā horoi, ngā hua tiaki makawe, me ngā hua tiaki tinana.

Ngā Āhuatanga

1. He roa te whakamakuku me te maeneene o te kiri
He nui ngā rōpū pai ki te wai kei roto i ngā mekameka taha o te polysodium glutamate taumaha-teitei, ā, he kaha tō rātou ki te mau i te wai.
He tino maeneene te kiri o te konutai poriglutamate taumaha-rahi, he maeneene te pā, he makuku hoki, ā, ka taea e ia te whakaiti i te piri o te waikawa hyaluronic.
2. Whakamakuku me te whakama, he pānga tahi me te HA
Ka taea e te konutai polyglutamate taumaha-iti te aukati i te mahi a ngā whākōkī HA i roto i te kiri, te whakapai ake i te pumau o te HA i roto i te kiri, me te whakanui ake i te ihirangi o te HA.
Kei te konutai polyglutamate taumaha-iti te pānga ki te aukati i te mahi tyrosinase, ka puta he pānga mā te kiri.
3. Whakanuia te ihirangi o ngā mea whakamakuku taiao i roto i te kiri
He iti rawa te taumaha ngota o te polyglutamate sodium taumaha ngota tino iti, he iti iho i te 10kDa, ā, he tere ake te uru ki te kiri, ka momona, ka makuku hoki te kiri.
Ka taea e te konutai polyglutamate taumaha ngota tino iti te whakanui ake i te ihirangi NMF o te stratum corneum, ā, ka whakarei ake i te kaha wai o te kiri.
