Sebenzisa izinto zokuthambisa ezinempilo

Izinto zokuthambisa ziyinxalenye yobomi bemihla ngemihla yamadoda nabafazi. Abantu abaninzi bafuna ukubonakala bekhangelekile kwaye baziva bonwabile, kwaye basebenzisa izinto zokuthambisa ukufezekisa oku. IQela eliSebenzayo lokusiNgqongileyo (i-EWG), umbutho ongenzi nzuzo ozinikele ekufundiseni abathengi ngesiqulatho seemveliso zezithambiso, uthi abasetyhini basebenzisa umndilili weemveliso zokhathalelo lobuqu ezili-12 ngosuku, kwaye amadoda asebenzisa isiqingatha soko.

Ngenxa yokuxhaphaka kwezithambiso eluntwini, kubalulekile ukuba ube ngumthengi onolwazi kwaye ofundileyo. Funda ukuba zithini izithambiso kunye nendlela ezikuchaphazela ngayo kunye nendalo.

I-FDA, ilebheli kunye nokhuseleko lwemveliso yobuhle

Abantu abaninzi bafuna iimveliso zobuhle ezenziwe ngezinto ezisempilweni, ezingenabungozi. Ngelishwa, akukho lula ukuba abathengi baqonde ukuba zeziphi iimveliso ezisempilweni kubo kunye nokusingqongileyo. Iilebheli ezithi iimveliso "ziluhlaza," "zezendalo," okanye "zezendalo" azithembekanga. Akukho arhente karhulumente inoxanduva lokuchaza okanye ukumisela ukwenziwa kwezithambiso.

Ulawulo lwezoKutya noLawulo lweMithi (i-FDA) alunamandla okubeka iliso kwizithambiso ngokusondeleyo njengoko kusenziwa kukutya nakwiziyobisi. I-FDA inegunya elithile kwezomthetho. Nangona kunjalo, iimveliso zokuthambisa kunye nezithako zazo (ngaphandle kwezongezo zombala) azikho phantsi kwemvume ye-FDA premarket.

Ngamanye amagama, i-FDA ayijongi ukuba imveliso ebanga ukuba "yiipesenti ezili-100 zezinto eziphilayo" iyinyani yeepesenti ye-organic. Ukongeza, i-FDA ayinakukukhumbula iimveliso eziyimfashini eziyingozi.

Kubalulekile ukuba wena, mthengi, waziswe kwaye uthenge iimveliso ezisempilweni nezikhuselekileyo kuwe nakwimeko-bume. Yazi ukuba ezinye iikhemikhali kwiimveliso ezithile zokuthambisa zinokuba yityhefu.

Ukuqonda "ukwakheka" kokwenza makeup

Ukukunceda wenze izigqibo unolwazi, Nazi iindidi ezine eziphambili zezithako eziyingozi ezisetyenziswa kwizithambiso kunye neemveliso zokhathalelo lomntu:

Izinto ezenziwa ngumdaka

Ngokutsho kweRoyal Society of Chemistry, ama-surfactants afumaneka kwiimveliso ezisetyenziselwa ukuhlamba. Ziphula izinyibilikisi ezinamafutha eziveliswa lulusu ukuze zikhukuliswe ngamanzi. Izinto ezingafunekiyo zidityaniswe nezongezo ezinje ngedayi, iziqholo, kunye neetyiwa kwiimveliso ezinje ngesiseko, ijeli yeshawari, ishampu kunye nethambiso lomzimba. Benza iimveliso eziqinileyo, bezivumela ukuba zisasazeke ngokulinganayo kwaye zicoca kwaye zenze amagwebu.

Ukujonga iipolym

Ezi zigcina ukufuma kulusu okanye ezinweleni. IGlycerin, into yendalo yeoyile yemifuno kunye namafutha ezilwanyana, iveliswa ngokwamashishini eshishini lezithambiso. Yeyona polymer indala, enexabiso eliphantsi, kunye neyona ndawo ithandwayo yimeko yeemeko.

Iipolymers ezimiselweyo zisetyenziswa kwiimveliso zeenwele ukutsala amanzi kunye nokuthambisa iinwele ngelixa kudumba ishafti. Bagcina iimveliso zingomi kwaye zizinzise iziqholo ukugcina amavumba angangeni kwiibhotile zeplastiki okanye kwimibhobho. Kananjalo benza iimveliso ezinje ngokucheba ikrimu ziziva zigudile kwaye zithe tyaba, kwaye ziyabathintela ekuncamatheleni kwisandla sakho.

Ukubulala

Izinto ezisigcinayo sisongezo esibaxhalabisayo abathengi. Zisetyenziselwa ukunciphisa ukukhula kwebhaktiriya kunye nokwandisa ixesha lokugcina imveliso. Oku kunokugcina imveliso inokubangela usulelo kulusu okanye kwamehlo. Umzi mveliso wezithambiso uzama izinto zokuthambisa ezizisebenzisayo, ezisebenzisa ioyile zezityalo okanye izicatshulwa ukuze zisebenze njengezikhusela indalo. Nangona kunjalo, ezi zinokucaphukisa ulusu okanye zibangele ukungabikho komzimba. Uninzi lunephunga elinamandla nelingathandekiyo.

Iphunga

Iphunga linokuba yeyona ndawo inobungozi kwimveliso yobuhle. Iphunga livame ukuqulethe iikhemikhali ezinokubangela ukungabikho komzimba. Unokufuna ukuqaphela ukuthintela nayiphi na imveliso equka igama elithi "ivumba elimnandi" kuluhlu lwazo lwezithako.

Izithako ezingavumelekanga

Ngokuka-FDA, ezi zithako zilandelayo azivumelekanga ngokusemthethweni kwizithambiso:

• bithionol
• I-chlorofluorocarbon yokuhambisa
• ikloroform
• i-halogenated salicylanilides, di-, tri-, metabromsalan kunye ne-tetrachlorosalicylanilide
• imethylene chloride
• IVinyl chloride
• izakhiwo eziqulethe i-zirconium
• Izinto zeenkomo ezingavumelekanga

Izithako ezithintelweyo

I-FDA ikwadwelisa ezi zinto zinokusetyenziswa kodwa zithintelwe ngokusemthethweni:

• hexachlorophene
• iikhompawundi zemekyuri
• ii-sunscreens ezisetyenziswa kwizithambiso

Eminye imiqobo

I-EWG ikwacebisa ezinye izithako zokuphepha, kubandakanya:

• benzalkonium chloride
• I-BHA (i-hydroxyanisole butylated)
• idayi yamalahle etha yamalahle kunye nezinye izithako zetela yamalahle, ezinje nge-aminophenol, diaminobenzene, kunye ne-phenylenediamine
• I-DMDM hydantoin kunye nebronopol
• i-formaldehyde
• Izithako ezidweliswe “njengevumba elimnandi”
• hydroquinone
• i-methylisothiazolinone kunye ne-methylchloroisothiazolinone
• yioxybenzone
• parabens, propyl, isopropyl, butyl, kunye isobutylparabens
• Ii-PEG / ceteareth / polyethylene iikhompawundi
• Ipetroleum distillates
• phthalates
• I-resorcinol
• i-retinyl palmitate kunye ne-retinol (i-vitamin A)
• toluene
• I-triclosan kunye ne-triclocarban

Iingxaki zokupakisha izithambiso

Ukukhetha izithambiso ezisempilweni kukwathetha ukukhetha ukupakishwa okukhuselekileyo kuwe kunye nokuba sempilweni komhlaba. Iingqayi ezinemilomo evulekileyo zinokungcoliseka ziintsholongwane. Ukupakishwa ngaphandle komoya, okungavumeli ukuba iintsholongwane zivelise, kukhethwa. Iimpompo ezinezivalo zendlela enye zinokugcina umoya ungangeni kwiphakheji evuliweyo, okwenza ungcoliseko lube nzima ngakumbi. Inkqubo yokuvelisa ngononophelo igcina imveliso iyinyumba njengoko ingena kwibhotile okanye ingqayi.

Imbonakalo

Izimonyo ziyinxalenye yobomi kubantu abaninzi, kwaye ukuthengisa kwabo kunokulahlekisa. Ukuba usebenzisa izinto zokuthambisa okanye iimveliso zokhathalelo lomntu, yaziswa ukuba yintoni na ngaphakathi kuzo. Ngokufunda iilebheli kwaye wenze uphando unokwenza izigqibo ezifundisiweyo, ezisempilweni xa uthenga kwaye usebenzisa iimveliso zezithambiso.
