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 and Lauramidopropyl Betaine are made from 3,3-dimethylaminopropylamine, often abbreviated as DMAPA. DMAPA is a dermal sensitizer. Therefore, manufacturers of Cocamidopropyl Betaine and Lauramidopropyl Betaine keep the levels of DMAPA in these ingredients as low as possible.These ingredients are generally sold as aqueous solutions that contain approximately 30% Cocamidopropyl Betaine or Lauramidopropyl Betaine.unctions reported for Cocamidopropyl Betaine and Lauramidopropyl Betaine include: antistatic agent, hair conditioning agent, skin-conditioning agent-miscellaneous, surfactant-cleansing agent, surfactant-foam booster and viscosity increasing agent-aqueous.
