Evaluation of quality of some babies plastic teats and bottles available in local markets.

This research was dealing with the quality of some babies plastic teats and bottles that available in local markets, they are offered a good service and fast circulation. Where sixteen of four types of babies plastic teats and bottles have been drawn from market. Each type from this stuff has been subjected to four tests. In this research investigations have been carried for the faults present in these stuff such as glutinousness, debacle, and changes occurred in color during sterilization using steam under pressure in autoclave apparatus. This research was also dealing with some asides of chemical composition of baby feeding bottles and rubber teats regarding the reducing the negative effects or hangovers of using baby feeding bottles for long periods. During examining the absorption of water of the stuff their weights after immersing the babies plastic teats and bottles in cold water for 24 hr. and in boiling water for one hour were found slightly diverse. In this research a significant differences in pH values of the extraction solution were noticed after subjection of babies plastic teats and bottles for one hour to a temperature of 120 ± 5 o C using autoclave apparatus, as well as a significant differences were noticed in the absorption of the extraction solution at wave lengths between 200 nm and 230 nm using UV-spectrophotometer. The absorption spectra for samples been tested have indicated a transfer of organic substances from samples to water solution, these materials could be hazard to baby health. Significant differences in weights in this research were found during experiments to determine the absorption of the babies plastic teats and bottles towards chemical solutions using 1% of sodium hypochlorite and after immersing the stuff in this solution for 24 hr.
