Kwita ku zuba, na cyane cyane kurinda izuba, ni kimwe mubyihuta-gukura ibice byisoko ryita kumuntu.Na none, kurinda UV ubu byinjizwa mubintu byinshi byo kwisiga bikoreshwa buri munsi (urugero, ibicuruzwa byita ku ruhu rwo mumaso hamwe no kwisiga byo kwisiga), mugihe abaguzi barushijeho kumenya ko gukenera kwizuba bitareba gusa ibiruhuko byo ku mucanga. .
Uyu munsi ushinzwe kwita ku zubaigomba kugera kuri SPF yo hejuru kandi igoye kurwego rwo kurinda UVA, mugihe nanone gukora ibicuruzwa byiza bihagije kugirango ushishikarize kubahiriza abaguzi, kandi bikoresha amafaranga menshi bihagije kugirango bihendutse mubihe byubukungu bitoroshye.
Imikorere nubwiza mubyukuri biterwa nundi; Kugwiza imikorere yibikorwa byakoreshejwe bituma ibicuruzwa bya SPF bihanishwa kurema urwego ruto rwa UV muyunguruzi. Ibi bituma uwashizeho umudendezo mwinshi wo koroshya ibyiyumvo byuruhu. Ibinyuranye, ubwiza bwibicuruzwa byiza bushishikariza abaguzi gukoresha ibicuruzwa byinshi bityo bakegera hafi ya SPF yanditseho.
Imikorere Ibiranga Kuzirikana mugihe uhitamo UV Muyunguruzi yo kwisiga
• Umutekano ugenewe itsinda ryanyuma-ukoresha- Akayunguruzo ka UV kose kageragejwe cyane kugirango tumenye neza ko kavukire kavukire; icyakora abantu bamwe bumva neza barashobora kugira allergic reaction kubwoko bwa UV muyunguruzi.
• Gukora neza kwa SPF- Ibi biterwa nuburebure bwumurambararo ntarengwa, ubunini bwikwirakwizwa, nubugari bwikwirakwizwa.
• Ikwirakwizwa ryagutse / UVA irinda umutekano- Ibihe bigezweho byizuba birasabwa kubahiriza ibipimo bimwe na bimwe byo kurinda UVA, ariko ibitakunze kumvikana neza nuko kurinda UVA nabyo bitanga umusanzu muri SPF.
• Ingaruka ku myumvire y'uruhu- Muyunguruzi zitandukanye za UV zigira ingaruka zitandukanye kumyumvire y'uruhu; kurugero rwamazi ya UV yungurura irashobora kumva "ifatanye" cyangwa "iremereye" kuruhu, mugihe akayunguruzo k'amazi gashiramo uruhu rwumye.
Kugaragara ku ruhu- Akayunguruzo kadasanzwe hamwe nuduce duto duto dushobora gutera umweru kuruhu iyo bikoreshejwe cyane; ibi mubisanzwe ntabwo byifuzwa, ariko mubisabwa bimwe (urugero: kwita ku zuba ryabana) birashobora kubonwa nkibyiza.
• Ifoto- Amashanyarazi menshi ya UV yungurura yangirika kuri UV, bityo bikagabanya imikorere yabyo; ariko izindi filteri zirashobora gufasha guhagarika ayo "foto-labile" muyunguruzi no kugabanya cyangwa gukumira kubora.
• Kurwanya amazi- Kwinjizamo amazi ya UV muyunguruzi hamwe n’amavuta ashingiye ku mavuta akenshi bitanga imbaraga zikomeye kuri SPF, ariko birashobora kugorana kugera ku kurwanya amazi.

Ibintu bigira ingaruka kumikorere ya UV Muyunguruzi
Ibiranga imikorere ya titanium dioxyde na zinc oxyde iratandukanye cyane bitewe numuntu kugiti cye cyihariye cyakoreshejwe, eg. gutwikira, imiterere yumubiri (ifu, gutatanya amavuta, gutatanya amazi).Abakoresha bagomba kugisha inama abatanga isoko mbere yo guhitamo icyiciro gikwiye kugirango bahuze intego zabo muri sisitemu yo gukora.
Imikorere ya peteroli ya elegitoronike UV iyungurura iterwa no gukomera kwayo mumyuka ikoreshwa mugutegura. Mubisanzwe, polar emollients ninziza nziza kumashanyarazi.
Imikorere ya UV muyunguruzi yose iterwa cyane nimyitwarire ya rheologiya yimikorere hamwe nubushobozi bwayo bwo gukora firime iringaniye, ihuza uruhu. Gukoresha abakora firime ikwiye hamwe ninyongera ya rheologiya akenshi bifasha kunoza imikorere ya filteri.
Ihuriro rishimishije rya UV muyunguruzi (synergies)
Hano hari byinshi bihuza UV muyunguruzi byerekana guhuza. Ingaruka nziza zo guhuza imbaraga zisanzwe zigerwaho muguhuza akayunguruzo kuzuzanya muburyo bumwe, urugero: -
• Guhuza amavuta-ashonga (cyangwa amavuta yatatanye) akayunguruzo hamwe nayungurura amazi (cyangwa akwirakwiza amazi).
• Guhuza UVA muyunguruzi na UVB muyunguruzi
• Guhuza ibishungura bidafite ingufu hamwe na filteri kama
Hariho kandi guhuza bimwe bishobora gutanga izindi nyungu, kurugero birazwi neza ko octocrylene ifasha gufotora-gutuza amafoto-labile muyunguruzi nka butyl mitoxydibenzoylmethane.
Icyakora umuntu agomba guhora azirikana imitungo yubwenge muriki gice. Hano hari patenti nyinshi zikubiyemo guhuza UV muyunguruzi hamwe nabashinzwe gukora inama basabwa guhora bagenzura ko guhuza umugambi bateganya gukoresha bitabangamiye ikindi kintu cya gatatu.
Hitamo iburyo bwa UV muyunguruzi yo kwisiga
Intambwe zikurikira zizagufasha guhitamo neza UV muyunguruzi (s) yo kwisiga:
1. Shiraho intego zisobanutse kubikorwa, imiterere yuburanga hamwe nibisabwa kubisabwa.
2. Reba akayunguruzo kemewe ku isoko ryagenewe.
3. Niba ufite chassis yihariye wifuza gukoresha, suzuma akayunguruzo kajyanye nizo chassis. Icyakora niba bishoboka nibyiza guhitamo gushungura mbere hanyuma ugashushanya formulaire hafi yabo. Ibi ni ukuri cyane hamwe na organic organique cyangwa uduce duto kayunguruzo.
4. Koresha inama zitangwa nabaguzi hamwe na / cyangwa ibikoresho byo guhanura nka BASF Sunscreen Simulator kugirango umenye guhuza bigombakugera kuri SPF yageneweintego za UVA.
Ihuriro rishobora noneho kugeragezwa mubikorwa. Muri vitro vitro SPF hamwe na UVA uburyo bwo gupima ni ingirakamaro muriki cyiciro kugirango berekane ibiteranya bitanga ibisubizo byiza mubijyanye nimikorere - amakuru menshi kubisabwa, gusobanura no kugabanya ibyo bizamini arashobora gukusanyirizwa hamwe na e-mahugurwa ya SpecialChem:UVA / SPF: Kunoza protocole yawe
Ibisubizo by'ibizamini, hamwe n'ibisubizo by'ibindi bizamini n'ibizamini (urugero: gutuza, gukora neza, kubungabunga uruhu, kumva uruhu), gushoboza uwashinzwe guhitamo amahitamo meza (s) kandi akanayobora iterambere ryiterambere ryimikorere.
