Nwoke, I. B.(2025). ASSESSMENT OF PHTHALATE COMPOUNDS IN SELECTED COSMETICS IN PORT HARCOURT MARKET

Abstract

This study assessed the concentrations of phthalate compounds in three commonly used cosmetics (aloe vera gel cream, pure white body lotion, and papaya cream) purchased from market in Port Harcourt, Rivers State, Nigeria. Samples were collected and subjected to solvent-based extraction and chromatographic determination. Results revealed that phthalates concentrations were highest in Aloe vera gel cream (2439 μg/kg), driven predominantly by di-isoheptyl phthalate. Pure White body lotion exhibited phthalate level of 1351 μg/kg. Although individual concentrations remained below current European Union and NAFDAC permissible limits. The findings confirm cosmetics as a modifiable source of EDC exposure in an urban Nigerian population and highlight product-specific contamination patterns influenced by formulation and intended function. The study provides data for these compounds in locally marketed cosmetics in Port Harcourt. It is recommended that NAFDAC introduce specific maximum limits and mandatory ingredient disclosure for EDCs, while manufacturers should prioritize safer alternatives. Expanded biomonitoring and broader product screening are urged to strengthen risk assessment and protect public health.
