ʻO ka waikawa lactic (sodium lactate) he mea hoʻohana nui i hoʻohana ʻia ma ke ʻano he preservative, exfoliant, moisturizer, a no ka hāʻawi ʻana i ka acidity i kahi hoʻolālā.I loko o ke kino, loaʻa ka lactic acid i loko o ke koko a me ka ʻiʻo ʻiʻo ma ke ʻano he huahana o ka metabolism o ka glucose a me ka glycogen.He mea ia o ka mea hoʻomaʻemaʻe maoli o ka ʻili.ʻOi aku ka maikaʻi o ka wai lactic acid ma mua o ka glycerin.Hōʻike nā haʻawina i ka hiki ke hoʻonui i ka mana paʻa wai o ka stratum corneum.Hōʻike pū lākou i ka pili pono o ka stratum corneum layer i ka absorption o ka lactic acid;ʻo ia hoʻi, ʻoi aku ka nui o ka waika lactic i hoʻopaʻa ʻia, ʻoi aku ka maʻalahi o ka papa stratum corneum.Hōʻike ka poʻe noiʻi ʻo ka hoʻohana mau ʻana i nā mea hoʻomākaukau i hoʻomākaukau ʻia me ka lactic acid i loko o ka hoʻopaʻa ʻana ma waena o 5 a me 12 pākēneka i hāʻawi i ka hoʻomaikaʻi haʻahaʻa a me ka haʻahaʻa i ka wrinkling maikaʻi a hoʻoikaika i ka ʻili palupalu.Hiki i kāna mau mea exfoliating ke kōkua i ke kaʻina o ka wehe ʻana i ka puaʻa nui mai ka ʻili o ka ʻili, a me ka hoʻomaikaʻi ʻana i ke ʻano o ka ʻili a me ka manaʻo.ʻO ka waikawa lactic kahi waikawa alpha hydroxy i loaʻa i loko o ka waiū ʻawaʻawa a me nā kumu ʻike liʻiliʻi ʻē aʻe, e like me ka pia, pickles, a me nā meaʻai i hana ʻia ma ke kaʻina o ka fermentation bacteria.He caustic ia ke hoʻopili ʻia i ka ʻili i nā ʻoluʻolu koʻikoʻi.
ʻO ka ʻakika Lactic kahi acidulant i loaʻa i loko o ka waiū, ka ʻiʻo, a me ka pia, akā pili maʻamau me ka waiū.he wai syrupy i loaʻa ma ke ʻano he 50 a me 88% wai wai, a hiki ke hui pū ʻia i ka wai a me ka waiʻona.He paʻa ka wela, nonvolatile, a he ʻono ka waiu waiu.hana ia ma ke ʻano he mea ʻono, preservative, a me ka acidity adjuster i nā meaʻai.Hoʻohana ʻia ia i nā ʻoliva Sepania e pale aku i ka palaha a hāʻawi i ka ʻono, i loko o ka pauka hua maloʻo e hoʻomaikaʻi ai i ka hoʻopuehu a me ka paʻi ʻana i nā waiwai, i nā pāpaʻi paʻakai, a me nā hui ʻana o ka saladi.
