Ke nānā nei ʻoe i nā ʻaoʻao kikoʻī huahana no Salicylic Acid CAS: 69-72-7, e ʻike ʻoe i ka ʻike koʻikoʻi e alakaʻi iā ʻoe i ka hoʻoholo ʻana.Hāʻawi kēia ʻaoʻao i nā kikoʻī e pili ana i ke kumu kūʻai, nā koho hōkeo, nā nui i loaʻa a me nā palapala hōʻoia maikaʻi.ʻO kā mākou Salicylic Acid mai kahi mea hana kaulana a hele i nā hana hoʻomalu maikaʻi e hōʻoia i kona maʻemaʻe a me kona ikaika.
Hoʻohui, hāʻawi mākou i nā māka like ʻole o ka salicylic acid, e ʻae iā ʻoe e koho i ka huahana i kūpono i kāu mau pono kikoʻī.Inā makemake ʻoe i ka helu cosmetic no ka mālama ʻana i ka ʻili a i ʻole ka lāʻau lapaʻau no ka lāʻau lapaʻau, ua uhi mākou iā ʻoe.Aia pū kā mākou hui loea e hāʻawi i ke kākoʻo ʻenehana a pane i nā nīnau āu e pili ana i ka huahana a i kāna noi.
I ka hopena, ʻo ka salicylic acid CAS: 69-72-7 kahi mea pono a me ka versatile pūhui.He mea ikaika ia i loko o nā huahana mālama ʻili a hāʻawi i nā hopena kūpono no ka haki a me nā maʻi ʻili ʻē aʻe.Eia kekahi, ʻoi aku ka nui o kāna hoʻohana ʻana i ka ʻoihana lāʻau lapaʻau, e lilo ia i mea nui i nā lāʻau lapaʻau he nui.Me kā mākou salicylic acid kiʻekiʻe a me ke kākoʻo o nā mea kūʻai aku, hoʻoikaika mākou e lilo i hoa hilinaʻi no kāu mau pono kemika.
