Squalene amapezeka mwachibadwa m'matupi athu. Ndi amodzi mwa lipids ochulukirapo omwe amapangidwa ndi maselo a khungu la munthu ndipo amapanga pafupifupi 10% ya sebum. Pamwamba pa khungu, imakhala ngati chotchinga, kuteteza khungu ku kutaya chinyezi komanso kuteteza thupi ku poizoni wa chilengedwe. M'thupi lenilenilo, chiwindi chimapanga squalene monga kalambula bwalo wa kolesterolini. Squalene ndi hydrocarbon yaunsaturated yochokera ku banja la triterpenoid, yomwe imapezeka ngati chigawo chachikulu cha mafuta a chiwindi mu mitundu ina ya shark zakuya. Kuonjezera apo, squalene ndi gawo la gawo losaponifiable la mafuta a masamba - azitona ndi amaranth. Squalene, ngati tikulankhula za mmene khungu la munthu, amachita monga antioxidant, moisturizer ndi pophika mafuta odzola, komanso ntchito zochizira matenda a khungu monga kutupa sebaceous glands, psoriasis kapena atypical dermatitis. Pamodzi ndi izi, squalene ndi antioxidant-rich emollient yomwe imagwiritsidwa ntchito ngati chowonjezera mu deodorants, ma balms a milomo, opaka milomo, moisturizers, sunscreens, ndi zinthu zambiri zokongola. Popeza kuti squalene "amatsanzira" zokometsera zachilengedwe za thupi la munthu, zimalowa mofulumira kudzera m'mabowo a khungu ndipo zimatengedwa mofulumira komanso popanda zotsalira. Mlingo wa squalene m'thupi umayamba kuchepa pambuyo pa zaka makumi awiri. Squalene imathandiza kuti khungu likhale losalala komanso kuti likhale losavuta, koma silimapangitsa kuti khungu likhale lamafuta. Madzi owala, opanda fungo opangidwa ndi squalene ali ndi antibacterial properties ndipo amatha kukhala othandiza pochiza chikanga. Odwala ziphuphu amatha kuchepetsa mafuta m'thupi pogwiritsa ntchito topical squalene. Kugwiritsa ntchito squalene kwa nthawi yayitali kumachepetsa makwinya, kumathandizira kuchiritsa zipsera, kukonza thupi lowonongeka ndi cheza cha ultraviolet, kumawunikira madontho ndikuchotsa mtundu wamtundu wa khungu polimbana ndi ma free radicals. Kupaka tsitsi, squalene imakhala ngati chowongolera, kusiya ulusi watsitsi wonyezimira, wofewa komanso wamphamvu. Kutengedwa pakamwa, squalene imateteza thupi ku matenda monga khansa, zotupa, rheumatism, ndi shingles.
Squalene ndi squalene Squalane ndi mtundu wa hydrogenated wa squalene momwe umalimbana kwambiri ndi okosijeni ukakumana ndi mpweya. Chifukwa squalane ndi yotsika mtengo, imasweka pang'onopang'ono, ndipo imakhala ndi nthawi yayitali kuposa squalene, ndiyo yomwe imagwiritsidwa ntchito kwambiri mu zodzoladzola, zomwe zimatha zaka ziwiri mutatsegula vial. Dzina lina la squalane ndi squalene ndi "mafuta a chiwindi cha shark". Chiwindi cha shaki zakuya monga chimaeras, shaki zopota pang'ono, shaki zakuda ndi ma spiny shark amaso oyera ndiye gwero lalikulu la squalene. Kukula kwapang'onopang'ono kwa shaki ndi kusabereka kosalekeza, limodzi ndi usodzi wochulukirachulukira, zikupangitsa kuti shaki zambiri zithe. Mu 2012, bungwe lopanda phindu la BLOOM linatulutsa lipoti lotchedwa "The Terrible Cost of Beauty: The Cosmetics Industry Is Killing Deep-Sea Sharks." Olemba lipotilo akuchenjeza anthu kuti shaki zochokera ku squalene zikhoza kutha m'zaka zikubwerazi. Bungwe la Food and Agriculture Organization (FAO) linanena kuti mitundu yoposa kota ya nsomba za shaki tsopano ikudyeredwa mwankhanza pofuna kuchita malonda. Mitundu yoposa 2 ya shaki yalembedwa mu Red Book ya International Union for Conservation of Nature and Natural Resources. Malinga ndi lipoti la BLOOM, kugwiritsa ntchito mafuta a chiwindi cha shark m'makampani opanga zodzoladzola kumayambitsa kufa kwa shaki pafupifupi 7 miliyoni zakuya m'nyanja chaka chilichonse. Pofuna kufulumizitsa njira yopezera mafuta, asodzi amatsatira mchitidwe wankhanza wotsatirawu: amadula chiwindi cha shaki ali m’ngalawamo, kenako n’kuponyanso m’nyanja nyama yolumala, koma ikadali yamoyo. Squalene imatha kupangidwa mopanga kapena kuchotsedwa ku mbewu monga njere za amaranth, azitona, chinangwa cha mpunga, ndi nyongolosi ya tirigu. Mukamagula squalene, muyenera kuyang'ana gwero lake, lomwe likuwonetsedwa patsamba lazogulitsa. Mlingo wa mankhwalawa uyenera kusankhidwa payekha, pafupifupi, 1000-2000 mg patsiku katatu. Mafuta a azitona ali ndi gawo lalikulu kwambiri la squalene pakati pa mafuta onse amasamba. Lili ndi 136-708 mg / 100 g ya squalene, pamene mafuta a chimanga ali ndi 19-36 mg / 100 g. Mafuta a Amaranth ndi gwero lamtengo wapatali la squalene. Mbewu za Amaranth zili ndi 7-XNUMX% lipids, ndipo lipids awa ndi amtengo wapatali chifukwa ali ndi zinthu monga squalene, unsaturated mafuta acids, vitamini E mu mawonekedwe a tocopherols, tocotrienols ndi phytosterols, omwe sapezeka pamodzi mu mafuta ena wamba.
