✦ Synopsis

Crystalline surfactant molecular complexes, the quite stable existence of which we firmly established through X-ray structural analysis, etc., were examined with respect to the protection from UV light and oxygen provided to their additive components. Structural analysis has revealed that the complex additives are stably occluded in the mother surfactant crystal matrix. Through the examination it was confirmed that additive components in a cationic complex crystal structure were perfectly protected from both UV light and oxygen. On the other hand, in anionics the additives were perfectly safe from UV attack, but from oxygen the change was rather accelerated in comparison with the effect of that on the pure condition.
