Abstract

Phthalates are compounds used principally as plasticizers, to impact flexibility, workability and durability to polymers used to contain consumer products such as water etc. These phthalates are not chemically bound to polymers; hence they are easily released and migrate into the containing consumer product. The leaching may take place in harsh conditions such as under the sun among others. Hence the “PA” sachet water was used as a case study. PA sachet water was subjected to different room temperatures; 25 oC, 45 oC, and 65 oC for 8 hours each day for 5 days. Liquid-liquid extraction of the phthalates from the different samples of water was carried out using dichloromethane. These samples were analyzed for benzyl butyl phthalate (BBP), di-butyl phthalate (DBP), di-2-ethylbutyl phthalate (DEHP), di (n-octyl) phthalates, DNOP, diisononyl phthalates (DINP using UV-VIS spectroscopy and GC-MS. The results showed that there was no leaching of phthalates into the water when the water was subjected to room temperature up to 65oC.
