- Bleach: E tlosa 'mala ho thepa ka ho pshatla matheba le mebala ka lik'hemik'hale.
2. Sepheo:
- Fluorescent Whitening Agents: E sebelisoa haholo-holo ho ntlafatsa ponahalo ea thepa ka ho etsa hore e bonahale e hloekile ebile e le mahlahahlaha.
- Bleach: E sebelisetsoa ho hloekisa, ho bolaea likokoana-hloko le ho tlosa matheba.
3. Kopo:
- Fluorescent Whitening Agent: E sebelisoa hangata ho polasetiki, masela le litlolo.
- Bleach: E sebelisoa lihlahisoa tsa ho hloekisa malapeng, lihlatsoetso tsa liaparo le lihloekisi tsa indasteri.
4. Sebopeho sa Lik'hemik'hale:
- Fluorescent Whitening Agents: Hangata metsoako ea tlhaho e kang stilbene derivatives, coumarins le benzoxazoles.
- Bleach: Metsoako e sa tsitsang joalo ka sodium hypochlorite (chlorine bleach) kapa metsoako ea organic joalo ka hydrogen peroxide (oxygen bleach).
Litlhokomelo tsa Polokeho le Tikoloho
