Abstract

Higher-molecular-weight phthalates, such as di-2-ethylhexyl phthalate, are primarily used as plasticizers to soften polyvinyl chloride products, while the lower-molecular-weight phthalates, such as diethyl phthalate, di-n-butyl phthalate, and butyl benzyl phthalate, are widely used as solvents to hold colour and scent in various consumer and personal care products.The average calculated concentration ranges of di-n-butyl phthalate,Di(2-ethylhexyl) phthalates and  Di-n-octyl phthalates in all the samples were 1.43-15.8µg/L, 0.0893-58.3µg/L and 0.107-51.5µg/L respectively. Among the analysed samples, Shaneinah Hamoodeh (yougort syrup) has the highest concentration of di-n-butyl phthalateand local cow milk has the lowest concentration. This may be due to nature of the packaging system during manufacturing in the industry. However, local Camel milk has the highest concentration of Di-n-octyl phthalates compared to Cow milk which has the lowest concentration, Values obtained are within acceptable limits.
