A dose of 0.5 milligrams of melatonin has been taken under the tongue for six days. For seizure disorders, doses of melatonin taken by mouth were 3-10 milligrams daily for 2-4 weeks to three months. For sleep (general), doses of melatonin taken by mouth were 0.3-10 milligrams.
The degradation of the synthetic, amphoteric surfactant, cocamidopropyl betaine (CAPB) and its toxicity to the marine macroalga, Ulva lactuca, has been evaluated using several different physiological test end-points over different periods of exposure up to 120 h.ell membrane damage, estimated from measurements of ion leakage, was detected only at a concentration of 40 mg l(-1) after 48 h of exposure to CAPB but by 120 h damage was evident at all measured concentrations above 10 mg l(-1).
Typical liquid laundry products contain about 4 % cocamidopropyl betaine, regular hand dishwashing liquids contain between 2 and 5 % of the betaine (with maximum values of up to 10 %), the concentrates contain 0.6 â 8 % (up to 11 % as a maximum value).alculation of absorbed cocamidopropyl betaine: 840 cm 2 x 0.01 cm x 0.1 (assumed skin absorption rate) x 40 mg/cm 3 = 33.6 mg 33.6 mg cocamidopropyl betaine absorbed in 24 hours = 33.6 mg/day The task duration is 10 minutes and the maximum frequency is once/day.
