Methyl-Hydroxyethylcellulose | CAS 9032-42-2

O le Methyl Hydroxyethylcellulose (MHEC) o se mea e maua mai i le cellulose ma le fua fa'atatau (C6H10O5)n. E maua mai i le cellulose, o se polymer masani e maua i totonu o puipui sela o laau. O le MHEC o loʻo faʻapipiʻiina e ala i le fesuiaiga o vailaʻau o le cellulose, faʻafeiloaʻi uma vaega methyl ma hydroxyethyl i luga o le cellulose backbone.

O nisi nei o manatu autu e uiga i le Methyl Hydroxyethylcellulose:

1. Fua Fa'ama'i: O le MHEC ose polymer e mafai ona solu vai ma se fausaga e tutusa ma le cellulose. O le faʻaopoopoga o vaega methyl ma hydroxyethyl e tuʻuina atu ai mea faʻapitoa i le polymer, e aofia ai le faʻaleleia atili o le solubility i le vai ma faʻaleleia atili le mafai ona mafiafia.
2. Meatotino: O le MHEC o loʻo faʻaalia ai le mafiafia sili ona lelei, faʻapipiʻiina o ata, ma mea faʻapipiʻi, e fetaui lelei mo le tele o faʻaoga. E masani ona faʻaaogaina e avea o se mafiafia, faʻamautu, ma le viscosity modifier i pisinisi eseese, e aofia ai le fausiaina, vailaʻau, tausiga a le tagata lava ia, ma faʻaofuofu.
3. Numera CAS: Ole numera CAS mo Methyl Hydroxyethylcellulose ole 9032-42-2. O numera o le CAS o fa'amatalaga fa'anumera tulaga ese e tu'uina atu i vaila'au fa'amalama e fa'afaigofie ai le fa'ailoaina ma le su'esu'eina i tusitusiga fa'asaienisi ma fa'amaumauga fa'atonu.
4. Talosaga: E maua e le MHEC le tele o le faʻaogaina i le fale faufale e avea o se mea faʻafefeteina i sima faʻavae sima, faʻapipiʻi tile, ma mea faʻavae gypsum. I vaila'au ma mea tau tausiga a le tagata lava ia, e fa'aaogaina e fai ma mea fa'apipi'i, ata tifaga muamua, ma le viscosity modifier i fa'apipi'i laupapa, fofo ophthalmic, kulimi, lotions, ma shampoos.
5. Tulaga Fa'atulafonoina: Methyl Hydroxyethylcellulose e masani ona manatu e saogalemu (GRAS) mo lona fa'aogaina i pisinisi eseese. Ae ui i lea, o mana'oga fa'atulafonoina fa'apitoa e ono fesuisuia'i e fa'atatau i le atunu'u po'o le itulagi o lo'o fa'aogaina. E taua tele le usita'ia o tulafono ma ta'iala talafeagai pe a fa'atūina oloa e iai le MHEC.

I le aotelega, o le Methyl Hydroxyethylcellulose o se mea e maua mai i le cellulose ma mea taua mo le tele o mea tau pisinisi ma pisinisi. O lona malosi e fa'aleleia ai le fa'aogaina o mea fa'apolopolo o fa'asologa e avea ai ma filifiliga sili mo le ausiaina o uiga fa'atinoga mana'omia i oloa eseese.
