ʻOkoʻa ka ʻano hana o ka titanium dioxide a me ka zinc oxide ma muli o nā waiwai pākahi o ka papa kikoʻī i hoʻohana ʻia, e laʻa. ka uhi ʻana, ke ʻano kino (ka pauka, ka hoʻopuehu ʻana i ka ʻaila, ka hoʻopuehu ʻana i ka wai).Pono nā mea hoʻohana e kūkākūkā me nā mea hoʻolako ma mua o ke koho ʻana i ka pae kūpono loa e hoʻokō i kā lākou mau pahuhopu hana i kā lākou ʻōnaehana hoʻonohonoho.
Hoʻopili ʻia ka maikaʻi o nā kānana UV organik hiki ke hoʻoheheʻe ʻia e ko lākou solubility i nā emollients i hoʻohana ʻia i ka hana. ʻO ka maʻamau, ʻo nā emollient polar ka mea hoʻoheheʻe maikaʻi loa no nā kānana organik.
