Te wāhanga matū hohe
Octyl methoxycinnamate
Te Octyl methoxycinnamate (OMC)Ko te Octyl methoxycinnamate (OMC) tētahi o ngā matū ārai rā e whakamahia whānuitia ana. Ko te Octyl methoxycinnamate (OMC) he tātari UVB me te ānau mimiti UV pai rawa atu o te 280~310 nm, he tere mimiti teitei, he haumaru pai, he iti te paitini, ā, he pai te wairewa ki ngā rauemi mata hinuhinu. E mōhiotia ana hoki ko te octanoate me te 2-ethylhexyl 4-methoxycinnamate. Kua whakaaetia te matū hei wāhanga whakapaipai i te United States me te European Union (EU) i ngā kukū o te 7.5-10%.
Benzophenone-3
Benzophenone-3Ko te (BP-3) he pare rā whānui-rahi wairewa-hinu e mimiti ana i ngā hihi UVB me ngā hihi UVA poto. Ka tere te waikura o te BP-3 i raro i te hihi ultraviolet, ka whakaiti i tōna whai huatanga, ā, ka puta he nui o ngā momo hāora tauhohe. I te Hononga o Amerika, ko te kukū mōrahi e whakaaetia ana o te BP-3 i roto i te pare rā he 6%.
Benzophenone -4
Benzophenone-4(BP-4) e whakamahia whānuitia ana hei mimiti hihi ultraviolet i ngā kukū tae atu ki te 10%. He rite te BP-4 ki te BP-3, he mea hanga mai i te benzophenone.
4-methylbenzyl camphor
Ko te 4-methylbenzylidene camphor (4-methylbenzylidene camphor, 4-MBC) enzacamene rānei he matū i ahu mai i te camphor waro e whakamahia ana hei mimiti UVB i roto i ngā kiriuhi ārai rā me ētahi atu mea whakapaipai.

He pānga tō te 4-MBC ki te whakararuraru i te pūnaha endocrine o te estrogen, e pā ana ki te tuaka tairoi, e aukati ana hoki i te mahi a te AChE. Nō reira, me tūpato te whakamahinga o te pare rā kei roto ēnei kai.
3-benzal camphor
He matū whai kiko te 3-benzylidene camphor (3-BC) e tata ana ki te 4-MBC. Ko te kukū mōrahi o tēnei matū e whakamahia ana i roto i ngā hua ārai rā i te Kotahitanga o Ūropi he 2%.
E rite ana ki te 4-MBC, e whakaahuatia ana hoki te 3-BC hei kaikawe e whakararuraru ana i te estrogen. Hei tāpiri, kua pūrongohia ka pā te 3-BC ki te CNS. Me tūpato anō te whakamahinga o te hinu ārai rā kei roto ēnei kai.
Okitirene
Ko te Octocrtriene (OC) he ester nō te rōpū cinnamate e mimiti ana i ngā hihi UVB me UVA, tae atu ki te 10% te kukū i roto i ngā hinu ārai rā me ngā mea whakapaipai o ia rā.
Waeine hohe ā-tinana
Ko ngā matū hohe e whakamahia ana i roto i ngā pare ārai rā ko te titanium dioxide (TiO2) me te zinc oxide (ZnO), ā, ko te nuinga o ēnei kukū he 5-10% mā te whakaata, mā te marara rānei i te hihi ultraviolet (UVR) hei whakatutuki i te kaupapa o te pare ārai rā.
Taihauāwhio
He kohuke paura mā te hauhāotaiuma i hangaia mai i te hauhāotaiuma me te hāora. He whānuitia te whakamahinga o te hauhāotaiuma i roto i te kai me ngā mea whakapaipai, nā tōna mā me te whai huatanga o ngā ārai rā UV.
He paura mā te konutea waikura, he āhuatanga tiaki, he āhuatanga purenga hoki. He ārai rā UV anō hoki e whakaata ana i ngā hihi UVA me UVB.
