- Conclusions:
- Lauroyl L-lysine was photodegraded in air by reaction with OH radicals by 50% within 1.856 h.
- Executive summary:
The photodegradation of the test item in air by reaction with OH radicals was calculated using EPIWIN v4.11, AOPWIN v1.92. Based on the reaction rate constant k=69.1625 x 10E-12 cm³/molecule x sec and an OH radical concentration of 1.5 x 10E6 OH/cm³ a half-life time t1/2 of 1.856 h was calculated.
