Kushandiswa
Arbutiniri mumakemikari ehydroquinone glycoside. Zita rayo remakemikari ndi4-Hydroquinone-alpha-D-glucopyranoside. Iri mumiti yakaita sebearberry nebilberry, uye chinhu chitsva chinobva chachena chisina kushatirwa, chisina allergy uye chinoenderana zvakanyanya neChemicalbook. Kune mapoka maviri emabasa ekuvaka uye ekushanda muchimiro chemamorekuru earbutin: rimwe ndiro glucose residue, uye rimwe iboka rephenolic hydroxyl. Alpha-arbutin iri muchimiro chehupfu huchena kusvika kugrey light uye inonyungudika zvakanyanya mumvura neethanol.
Alpha-arbutinine simba rakanaka rekurapa mavanga anokonzerwa nekutsva kwe ultraviolet, uye ine simba rakanaka rekudzivirira kuzvimba, kugadzirisa uye kuchena. Inogona kudzivirira kugadzirwa nekuiswa kwe melanin uye kubvisa mavanga ekukwegura nemavanga.
Nzira yekuchenesa alpha-arbutin ndeyekudzivirira zvakananga kushanda kwetyrosinase, nokudaro ichideredza kugadzirwa kwemelanin, pane kuzadzisa chinangwa chekuderedza kugadzirwa kwemelanin nekudzivisa kukura kwemasero kana kuratidzwa kwegene retyrosinase. Sezvo alpha-arbutin iri chinhu chinoshanda uye chakachengeteka chekuchenesa masero, makambani mazhinji ekushongedza masero ari munyika nekune dzimwe nyika akatoshandisa alpha-arbutin pachinzvimbo chebeta-arbutin sechinhu chinowedzera kuchena. Alpha-arbutin chinhu chemakemikari. Kufanana nearbutin, alpha-arbutin inogona kudzivirira kugadzirwa nekuiswa kwemelanin uye kubvisa mavanga ezera nemavanga. Zvidzidzo zvakaratidza kuti alpha-arbutin inogona kudzivirira kushanda kwetyrosinase pahuwandu hwakaderera, uye mhedzisiro yayo yekudzivisa tyrosinase iri nani pane yearbutin. Alpha-arbutin inogona kushandiswa sechinhu chinodzivirira masero muzvizoro.
Kurongedza uye Kutumira
25KG/Drum kana zvichienderana nezvinodiwa nevatengi.
Ndezvezvinhu zvakajairika uye zvinogona kutumirwa negungwa nemhepo
Chengeta uye chengeta
Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
