β-cyclodextrin i-CAS 75859-9-9-9

Inkcazo emfutshane:

I-β-cyclodextrin i-mhlophe kwi-rystalline emhlophe ye-crystalline. Inyibilika emanzini ukwenza isisombululo esicacileyo kunye nencasa emnandi kakhulu. Ubume be-β-cyclodexrin yenza ukuba ukubandakanyeka ukubandakanyeka kweyona mimandla yeendwendwe, eyiyona ndawo iphambili kwisicelo sayo kwindawo yamayeza, ukutya kunye namanye amashishini.

I-β-cyclodextrin inyibilika emanzini kubushushu begumbi. Iyanyibilikisa ukwenza isisombululo esicacileyo. Ukunyibiliza kuyahluka ngeqondo lobushushu kunye ne-PH, kunye ne-β-cyclodextrin ikwanyibilika kwezinye izinyibilikisi, nangona kungumncinci. Iyakwazi ukwenza ukubandakanywa kwabantu ngeendlela ezahlukeneyo, ezonyusa ukuba luncedo kwizicelo ezahlukeneyo, kubandakanya amayeza kunye nokutya.

Ukugcinwa

Le mveliso kufuneka itywinwe kwaye igcinwe.

1. Iqondo lobushushu: β-cyclodexrin kwivenkile epholileyo neyomileyo, ngokukhethekileyo kubushushu begumbi (15-25 °). Kulumkele ukuveza amaqondo obushushu aphezulu.

2. Umswakazi: Nceda uyigcine kwimeko yokufuma enzonzobila, njengoko umswakama uya kuchaphazela uzinzo kunye nokuluka.

I-3. Isikhongozelo: β-cyclodexrin Sebenzisa izikhongozeli zomoya ukukhusela ukufuma nongcoliseko. Iglasi okanye izixhobo ezisemgangathweni zeplastiki eziphezulu zombini zilungile.

4. Ukukhanya: Nceda ugcine kude nokukhanya kwelanga ngqo kunye nemithombo yokukhanya eqinileyo, njengoko ukuboniswa ixesha elide kuya kubangela i-computer to de vegrade.

I-5. UBomi beShelsi: Jonga iingcebiso zomenzi wobomi beshelufa kunye nomhla wokuphelelwa kunye nokusetyenziswa ngaphakathi kweso siphumo seziphumo ezilungileyo.

Ngaba i-β-cyclodexrin iyingozi?

I-β-cyclodexrin ithathelwa ingqalelo njengetyhefu kwaye ikhuselekile ukuze isetyenziswe kwizicelo ezahlukeneyo, kubandakanya amayeza, ukutya kunye ne-cosmetics. Ayichazwanga njengezinto ezinobungozi eziphantsi kweemeko eziqhelekileyo zokuphatha kunye nokusetyenziswa. Nangona kunjalo, njengayo nayiphi na imichiza, kubalulekile ukulandela iinkqubo zokhuseleko ezisemgangathweni:
