I-Hydroquinone kwiKhemistri yezeMizi-mveliso kunye neZithambiso

IHydroquinone (benzene-1,4-diol) sisithako esisetyenziswa kakhulu kwimizi-mveliso esilwa ne-antioxidant kunye ne-arhente yokunciphisa. Kwindawo yokugcina kunye nokuthutha i-monomer, isetyenziswa kwi-concentration ephantsi (50–200 ppm) njengesithako esikhawulezayo sokuthintela ukupholisha kwangaphambili kwe-acrylic acid, i-styrene, kunye ne-methyl methacrylate. Kwi-raber compounding, isebenza njenge-antioxidant. Ngokwe-cosmetic, sisithako esisebenzayo esiqhelekileyo kwi-prescription kunye ne-OTC skin-lightening formulations, isebenza njengesithinteli se-enzyme tyrosinase kwi-melanin biosynthesis.

Amabanga kunye nobonelelo

I-Terracore inika umgangatho wobugcisa (izicelo zokuthintela imboni) kunye nomgangatho wezithambiso/wamayeza (olawulwa ukusetyenziswa kwesikhumba). Zombini ezi zigaba zikwiingxowa zephepha ezinee-25 kg. I-COA ibandakanya ubumsulwa nge-redox titration, i-melting point, kunye nombala (APHA). Isikhokelo sokuhlelwa kwe-SDS epheleleyo kunye ne-CMR siyabonelelwa.
