Ipolishi yesikhonkwane, i-sunscreen, isiseko okanye ukufihla yimizekelo yeemveliso zemihla ngemihla eziqukethe izinto ezinetyhefu yomzimba, abantu abaninzi abangazaziyo.

Ezi mveliso zinokuba neemveliso ezinetyhefu zomzimba, ezinje ngeToluene, Oxybenzone, Parabens okanye Sulfates, ekufuneka ithintelwe ngokujonga ileyibheli yeemveliso ezithengiweyo.

Iimveliso ezi-5 ezineziyobisi ezinobungozi

Ke, ezinye iimveliso ezisetyenziswa mihla le eziqulatha izinto ezinobungozi empilweni zibandakanya:

1. Iipilisi zenzipho

Bahlala bequkethe i-Toluene ekwakhiweni kwabo, i-hydrocarbon enuka kamnandi, ngaphandle kokufaka umbala kunye nevumba elimnandi, elicaphukisa ulusu, amehlo kunye nomqala. Eli qela linokwaziwa ngokuba yi-methylbenzene, kwaye lisetyenziswa kakhulu kwiipeyinti, ivanishi kunye nentlaka okanye iimveliso ezithile zokuthambisa, ngenxa yesiphumo sayo sokunyibilika.

Ukuthintela ukubhencwa kule arhente, kuya kufuneka uphephe ukuthenga iimveliso ekubunjweni kwazo ngokubhekisa kwileyibhile yemveliso. Kwiileyibhile imveliso inokukhankanywa ngamagama ahlukeneyo, njengoko inokwaziwa ngokuba yiToluene, Methylbenzene okanye iToluene okanye iMethylbenzene, ukuba ileyibhile ibhalwe ngesiNgesi.

2. Izikhuseli elangeni

Uninzi lwazo luqulathe i-oxybenzone ekwakhiweni kwazo, iyeza elenza amayeza elinakho ukufunxa i-UVB kunye ne-UVA radiation, oko ke kunciphisa ukungena kwemitha kulusu, okunciphisa umngcipheko wokonakaliswa kwe-DNA. Eli chiza linokufumaneka nakwezinye iimveliso zokuthambisa ngokukhusela elangeni, kwaye kunokwaziwa ngokuba yi-2-hydroxy-4-methoxybenzophenone. Nangona iluncedo kakhulu ekukhuseleni ulusu, inokuba noxanduva lokubangela ukucaphuka, i-dermatitis kunye nemingxunya kulusu, ngakumbi kubantu abanolwazelelelo okanye abanembali yokungezwani nezinto ezithile, njengoko iphelela ekungeneni kwesikhumba.

Ukuthintela ukuvezwa kwesi siyobisi, kuya kufuneka uphephe ukuthenga ukhuseleko okanye iimveliso zezithambiso kule arhente ekubunjweni kwayo, ujonge la magama alandelayo kwiilebheli: Oxybenzone, 2-hydroxy-4-methoxybenzophenone, 2-hydroxy-4-methoxybenzophenone okanye njenge yioxybenzone.

3. Iisiseko kunye noLungiso

Banokuqulatha ii-Parabens ekubunjweni kwabo, izinto ezinokubangela ukucaphuka okanye ukuphendula okwaliwa, ukongeza ekuphazamiseni imveliso yehomoni estrogen, njengoko ifunxwe lulusu.

Iiparbens zingasetyenziselwa kwimilebe yomlomo, into yokuthambisa umzimba okanye iimveliso zokucheba, zisebenza njengezilondolozi, kwaye zinokongezwa njengezongezo ekutyeni. Ukuthintela ukusebenzisa iimveliso ezinee-parabens, kubalulekile ukuba ujonge iilebheli zokupakisha, ujonge amagama eParabens okanye ukuvuyisana, okanye ezona ntlobo zixhaphakileyo ezibandakanya iMethylparaben, Propylparaben, Ethylparaben kunye neButylparaben.

4. IiShampoo

Banokuqulatha iiSulphate okanye iSodium Lauryl Sulfate ekubunjweni kwabo, iicompreasing compounds ezijongene nokuvelisa amagwebu, ngenxa yeepropathi zabo ezinamandla. Ukongeza, eli khompawundi likwasetyenziswa kwiimveliso zokucoca ulusu, ukususa izinto zokuthambisa okanye iityuwa zokuhlamba, ngenxa yesakhono sayo sokususa ioyile eluswini, njengoko isisidenge esinamandla. Ezi zinto zinokucaphukisa ulusu namehlo, kwaye zinokubangela ubomvu, ukurhawuzelela okanye ukudumba kule mimandla. Ukongeza, xa zisetyenziswa kwiishampu zinokususa ukhuselo lwendalo lweenwele, zome kwaye zibangele ukuba zaphuke.

Ukuthintela ukuvezwa kwesi siza, kuya kufuneka uphephe ukuthenga ii-Shampoos okanye iimveliso zokucoca ulusu ngaphandle kweesulphate, ujonge la magama alandelayo kwiileyibhile: i-sodium lauryl sulphate, i-sodium lauryl ether sulphate, i-sodium lauryl sulphate okanye i-sodium lauryl ether sulfate.

5. Idayi yeenwele

Isenokuqulatha isikhokelo ekubunjweni kwayo, intsimbi enzima ethi ngobuninzi bayo ibe yingozi kwizilwanyana nasebantwini, kwaye iyingozi nakwimeko esingqongileyo. Esi sinyithi asisetyenziswanga kuphela kwidayi yeenwele kodwa nakwezinye iimveliso zokuthambisa okanye zobuhle ezinje ngemilebe yomlomo, eqokelelwa emzimbeni ekuhambeni kwexesha. Ukuqokelelwa kwayo kunokubangela iingxaki ezininzi ezinjengokugabha, ukugabha, ukuqaqamba, ukozela, intloko ebuhlungu, ukuba nochuku kunye nokuba buthathaka kwezihlunu, umzekelo.

Kwidayi yeenwele, ilothe inokufumaneka phantsi kwegama i-acetate ekhokelayo, kwaye ukunqanda ukubonwa kwesi sinyithi sinzima kufuneka usoloko ujonga iilebheli yedayi yeenwele oza kuyisebenzisa.
