Lactic acid (sodium lactate) ndi zinthu zambiri zomwe zimagwiritsidwa ntchito ngati chosungira, chotulutsa, chonyowa, komanso kupereka acidity pakupanga.M'thupi, lactic acid imapezeka m'magazi ndi minofu monga chotulukapo cha kagayidwe ka shuga ndi glycogen.Komanso ndi chigawo chimodzi cha zinthu zachilengedwe moisturizing khungu.Lactic acid imakhala ndi madzi abwino kuposa glycerin.Kafukufuku akuwonetsa kuthekera kowonjezera mphamvu yosungira madzi ya stratum corneum.Amasonyezanso kuti pliability ya stratum corneum wosanjikiza imagwirizana kwambiri ndi kuyamwa kwa lactic acid;ndiko kuti, kuchuluka kwa lactic acid komwe kumamwa, kumapangitsa kuti stratum corneum wosanjikiza ikhale yosavuta.Ochita kafukufuku akuwonetsa kuti kugwiritsa ntchito mankhwala opangidwa ndi lactic acid m'magulu apakati pa 5 ndi 12 peresenti kumapangitsa kuti makwinya abwino azikhala pang'ono kapena pang'ono komanso amalimbikitsa khungu lofewa komanso losalala.Kutulutsa kwake kungathandize pakuchotsa pigment yochulukirapo pamwamba pa khungu, komanso kukonza mawonekedwe a khungu ndi kumva.Lactic acid ndi alpha hydroxy acid yomwe imapezeka mu mkaka wowawasa ndi zina zochepa zodziwika bwino, monga mowa, pickles, ndi zakudya zomwe zimapangidwa kudzera mu fermentation ya bakiteriya.Ndi caustic pamene ntchito pakhungu mu kwambiri moyikirapo njira.
Lactic Acid ndi acidulant yomwe ndi asidi yachilengedwe yomwe imapezeka mu mkaka, nyama, ndi mowa, koma nthawi zambiri imagwirizanitsidwa ndi mkaka.ndi madzi amadzimadzi omwe amapezeka ngati 50 ndi 88% amadzimadzi, ndipo amasokonekera m'madzi ndi mowa.Ndi kutentha kosasunthika, kosasunthika, ndipo kumakhala ndi kukoma kosalala, mkaka wa asidi.imagwira ntchito ngati chokometsera, chosungira, komanso chosintha acidity muzakudya.Amagwiritsidwa ntchito m'maolivi a ku Spain kuti asawonongeke komanso kuti azitha kununkhira, mu ufa wa dzira wowuma kuti apititse patsogolo kufalikira ndi kukwapula, muzopaka tchizi, ndi zosakaniza za saladi.
