Ingirakamaro
Amasomo ya Chimique:Ibindi bikoresha -> Bitunganijwe
Inseko ya kanonical:Coc (= o) c1 = cc = c (c = c1) o
Ikoresha:Methylparan niryo sori rya methyl inzoga na p-hydroxybenzan Uburyo busa, nka Ethyl P-Hydroxybenzoate (paraben b) na propyrol p-hydroxybenzoate (Nepalroxybenzoate (NepalroxBenzoate (NepalroxBenzoate (Nepalrose C), kandi ifite ibihano .Ibicuruzwa birakazana uruhu. Parambens nimwe mu itsinda rikoreshwa cyane ryibigenewe mu kwisiga, imiti, n'inganda. Parambe Gutanga ibikorwa bya bagiteri nigicucu birwanya umubare utandukanye wibinyabuzima, kandi ufatwa nkumutekano wo gukoresha mugukosora, cyane cyane ukurikije ubushobozi bwo gukangurira make. Isuzuma ryibigenewe kugirango rikoreshwe mu kiruhuko cyo kwisiga urutonde rwigice cya parabene hagati yo gukangurira make. Umubare wibanze ukoreshwa mugukosora biratandukanye hagati ya 0.03 na 0.30 ku ijana, bitewe nibisabwa. Dukurikije isomero ry'igihugu ry'igihugu, ibihanga biboneka bisanzwe mu mbuto ntoya - nubwo nazo zishobora gukorwa muri buri kintu kiva mu isuku n'indashyikirwa kandi bifasha ibi bicuruzwa bikomeza gukora neza. Rabach avuga ko ari chora-yuzuyemo imitungo ya anti-fungal na antibacteri, ikora ibitangaza kugirango yongere ubuzima bwibintu byuruhu, umusatsi, nibicuruzwa byisiga.
Methylparango numukozi urwanya ifu yera itemba. Irakora kurwanya umusemburo kandi ikabumba hejuru ya ph. Reba parabens. Methyl 4-hydroxybenzoate ikoreshwa nkumukozi urwanya upti-fungal. Irakoreshwa kandi kurinda ibiryo, ibinyobwa no kwisiga. Ikora nkibinyomoje byo gukura kw'ibumba no kugabanya urugero ya bagiteri kandi nk'ikinyabiziga cyo gukemura chphthalimic.
Intangiriro irambuye
Methylparant ni uguteka bisanzwe bikoreshwa muburyo bwo kwisiga kandi bwita kugiti cyawe. Numuryango wumuryango wa paraben, urimo abandi barinzwe nka rotylparantan, propylparaban, na butylparaban, na buylparaban.Hari ingingo zimwe na zimwe zerekeye methylparango:
Kubungabunga: Methylparant yo kwisiga no kwisiga no kwitondera kugiti cyawe kugirango wirinde gukura no gukwirakwiza mikorobe nka bagiteri na fungi. Ifasha kwagura ubuzima bwibicuruzwa nibikomeza ubuziranenge n'umutekano.
Umutekano:Methyparango yiga cyane kandi afatwa neza ko akoreshwa mu kwisiga no kwita ku bicuruzwa bishinzwe kugengwa n'ibiribwa no mu biyobyabwenge (SCCS), n'ibikoresho byo kwisiga.
Gukoresha cyane:Methylparan murashobora kubisanga mubicuruzwa bitandukanye, harimo amavuta, amavuta, shampoos, gutondekanya, maquillants, na sumorants, na sumorants. Byakoreshejwe cyane kubera imikorere yayo, gutuza, no guhuza hamwe nibitekerezo byinshi byitangaza.
Ibindi byakambaro: Methylparan ikunze gukoreshwa hamwe nandi makuru (nka Ethylparan, Propyparaban, na Butylparaban) gutanga ibintu byagutse byo kurengera uburinzi budahwitse.
Ubundi buryo bwo kubungabunga:Mu myaka yashize, hari igihe cyongerewe abaguzi basaba ubundi buryo. Nkigisubizo, amasosiyete amwe yisi yatangiye gukoresha ubundi buryo bworoshye cyangwa ahitamo kubungabunga neza-kubuntu. Ariko, methylparaban ikomeje gukoreshwa cyane kandi yemerwa kurinda inganda.
Ni ngombwa kumenya ko mu gihe methyparabe yiga cyane kandi bifatwa nk'imitekano yo gukoresha, abantu bamwe bashobora guhura na senyuka cyangwa ibisubizo bya allergique kuri yo, kimwe na kimwe. Niba ufite impungenge cyangwa ibibazo byihariye bijyanye nibikoresho byo kwisiga, nibyiza kubigisha inama ya dermatologue cyangwa umwuga wubuzima.
Gusaba
Methylparan ikoreshwa cyane cyane nk'ibidukikije mubyitayeho bitandukanye, kwisiga, nibicuruzwa byimiti. Intego nyamukuru yayo ni ukubuza imikurire ya bagiteri, umusemburo, na mold, bityo bikange ubuzima bushya no guharanira umutekano wibi bicuruzwa. Hano hari porogaramu imwe ya methylparaben:
Ibicuruzwa byo ku ruhuMethylparan murashobora kubisanga muri moisturizers, isuku, maskers, toners, hamwe nibindi bicuruzwa byuruhu kugirango bikomeze ubuziranenge kandi bikumira indwara yangiza microbial.
Ibicuruzwa by'Umusatsi:Methylparan ikoreshwa muri shampoos, icyuma, masike yumusatsi, hamwe nibicuruzwa byimitsi kugirango birinde formula yabo kandi bibuza imikurire ya mikorobe.
Ibicuruzwa byo kwita ku mubiri:Methyparaben akenshi yongeweho kumavuta yumubiri, umubiri wo gukaraba, deodorants, nibindi bintu byita kugiti cyawe kugirango wirinde kwangirika no gukomeza umutekano.
Ibicuruzwa:Methylparan ikoreshwa muburyo butandukanye bwo kwisiga, harimo urufatiro, ifu, eyeshadows, ihindagurika, no gukumira imikurire ya bagiteri na fungi.
Ibicuruzwa bya farumasi:Methyparan irashobora kuboneka mu guhagararwa kwakanwa, amavuta, amavuta, hamwe nibindi bikoresho bya farumasi nkibibangamira umutekano no gukumira umwanda.
Ni ngombwa kumenya ko gukoresha methylparan ibicuruzwa bigengwa n'abayobozi nka FDA (muri Amerika) na komisiyo y'Uburayi muri EU. Izi nzego zashyizeho imipaka yo gukoresha methyparan hamwe nabandi barinda kurinda ibicuruzwa.
