Kojic Acide Dipalmitate: Ibikoresho bishya byera byera bihamye kuruta Acide ya Kojic

● Niki Kojic Acide Dipalmitate?

Kumenyekanisha kubikoresho fatizo: Guhanga udushya kuva acide kojic kugeza ibinure bikomoka kumavuta

Dipalmitate ya Kojic (CAS No.: 79725-98-7) ni inkomoko ikomoka kuri acide kojic, itegurwa no guhuza aside ya kojic na aside palmitike. Inzira ya molekuline ni C₃₈H₆₆O₆ naho uburemere bwa molekile ni 618.93. Acide ya Kojic yabanje gukomoka ku bicuruzwa bya fermentation yibihumyo nka Aspergillus oryzae kandi bikoreshwa cyane mukubungabunga ibiryo no kwera, ariko amazi yabyo hamwe no kudahungabana kumucyo, ubushyuhe nicyuma bigabanya ikoreshwa ryayo. Dipalmitate ya Kojic ihindurwa na esterification, ntabwo igumana gusa ibikorwa byera bya acide kojic, ahubwo inatezimbere cyane ituze ryayo hamwe no gukomera kwamavuta, bigatuma iba inyenyeri mubikorwa byo kwisiga.

Igikorwa cyayo cyo gutegura kirimo synthesis ya chimique na tekinoroji ya bioenzymatic hydrolysis. Ikoranabuhanga rigezweho ritezimbere uburyo bwo kwitwara (nkubushyuhe bwo hejuru bwo hejuru cyangwa enzyme catisime) kugirango harebwe niba ibicuruzwa byera ari 98% kandi byujuje ubuziranenge bwo kwisiga.

Kojic aside dipalmitateni ifu yera yijimye yumuhondo ya kristaline ifite aho ishonga ya 92-96 ° C nubucucike bwa 0,99 g / cm³. Irashobora gushonga mumavuta yubutare, esters na Ethanol ishyushye, ariko ntigashonga mumazi. Amatsinda ya hydroxyl mumiterere yayo ya molekuline arasuzumwa, yirinda guhuza hydrogène nibindi bikoresho byo kwisiga (nka preservatives na sunscreens) kandi bigateza imbere imikorere.

Ibyiza byingenzi bya kojic aside dipalmitate:

Gufata amafoto:Ugereranije na acide kojic, urumuri rwayo nubushyuhe biriyongera cyane, birinda ibara riterwa no guhura na ioni.

Ibiranga ibinure:Irashobora gushonga byoroshye muburyo bwamavuta-fase, irashobora kwinjira neza muri stratum corneum yuruhu, kandi ikongera imikorere neza.

● Ni izihe nyunguKojic Acide Dipalmitate?

Kojic aside dipalmitate igera ku ngaruka zo kwita ku ruhu hakoreshejwe uburyo bwinshi:

1. Kwera cyane cyane:

Kubuza ibikorwa bya tyrosinase: Mugukata ion z'umuringa (Cu²⁺), irabuza inzira ya melanin inzira, kandi ifite ingaruka zo kwera kuruta acide kojic. Amavuriro yerekana ko igipimo cyayo cya melanin gishobora kugera kuri 80%.

Korohereza ibibanza:Kojic Acide Dipalmitateifite ingaruka zikomeye zo gutera imbere kuri pigmentation nkibibara byimyaka, ibimenyetso birambuye, amavunja, nibindi ..

2. Antioxydants na anti-gusaza:

Ifite ubushobozi budasanzwe bwo gusakara, igabanya ultraviolet iterwa na okiside yangiza, itinda kwangirika kwa kolagen, kandi ifasha mukurwanya inkari.

3. Ubwitonzi n'umutekano:

Yashyizwe ku rutonde rwibikoresho byo kwisiga byizewe na CTFA yo muri Amerika, Umuryango w’ubumwe bw’ibihugu by’Uburayi n’ubuyobozi bushinzwe ibiryo n’ibiyobyabwenge mu Bushinwa. Ntabwo irakaza kandi ibereye uruhu rworoshye.

● Nibiki Bikoreshwa Kojic Acide Dipalmitate ?

1. Inganda zo kwisiga:

Ibicuruzwa byera: Ongeraho amavuta yo kwisiga, essence (dosage isabwa 1% -3%), masike, nibindi, nko guhuza ibikomoka kuri glucosamine kugirango bikubye kabiri ingaruka zo kwera.

Izuba ryizuba no gusana: Korana nizuba ryumubiri nka zinc oxyde kugirango urinde UV kurinda no gusana ibyangiritse.

Ibicuruzwa birwanya gusaza: Byakoreshejwe mumavuta arwanya inkari hamwe na cream yijisho kugirango ugabanye imirongo myiza.

2. Ubuvuzi no kwitabwaho bidasanzwe:

Shakisha imikoreshereze yacyo mu kuvura indwara ziterwa na pigmentary (nka chloasma) no gusana pigment nyuma yo gutwikwa.

3. Imirima ivuka:

Ikoreshwa rya nanotehnologiya: Kunoza ituze ryibigize hifashishijwe ikoranabuhanga rya ensapsulation, kugera kurekura igihe kirekire, no kuzamura umusaruro.
