Additional information

Aluminium ammonium sulfate instantaneously dissociates in water in its two components salts: aluminium sulfate and ammonium sulfate and further into the aluminium cation (Al3+), the ammonium cation (NH4+) and the sulfate anion (SO42-).

As aluminium ammonium sulfate is an inorganic salt it is not expected to be degrated by light. The dissociation salts formed in water are also not thought to be subject to photo transformation.
