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).
Cocamidopropyl betaine (CAPB) is an organic compound derived from coconut oil and dimethylaminopropylamine.It is a zwitterion, consisting of both a quaternary ammonium cation and a carboxylate. CAPB is available as viscous pale yellow solution that is used as a surfactant in personal care products.The name reflects that the major part of the molecule, the lauric acid group, is derived from coconut oil.APB is available as viscous pale yellow solution that is used as a surfactant in personal care products. The name reflects that the major part of the molecule, the lauric acid group, is derived from coconut oil.
