Quantification and Characterization of Microplastics in Five Popular Indian Toothpaste Brands - A Comprehensive Analysis
Summary
Researchers analyzed five popular Indian toothpaste brands for microplastic contamination and found significant variations in concentration and polymer types across brands. One brand contained the highest microplastic concentration at 0.248 grams per gram of toothpaste, with particles up to 30 micrometers including PET, polypropylene, and PTFE. The study highlights that personal care products remain a direct source of microplastic exposure and suggests that regulatory oversight of microplastic ingredients in toothpaste is needed.
This research has investigated the presence and composition of microplastics in five popular toothpaste brands in India. Using a novel wet peroxide digestion method, the study successfully isolated and quantified microplastics in each brand, highlighting significant variations in concentration and polymer types. Sample S4 had the highest microplastic concentration (0.248 g/g) and the largest particle size (30 micrometers), while other brands exhibited lower levels. FTIR and AFM analyses identified multiple polymer types, including PET, PP, and PTFE, with sample S4 displaying complex surface topography, indicative of increased environmental interaction and pollutant absorption. One-way ANOVA confirmed significant differences in microplastic particle sizes across the brands. The study also performed principal component analysis (PCA), showing the intricate co-occurrence of polymers across samples, suggesting synergistic ecotoxicological effects. The results raise concerns about the potential health risks of daily exposure to microplastics through oral hygiene products, as well as the broader environmental implications, such as bioaccumulation in aquatic systems. The study calls for stricter regulation of microplastics in consumer products and further investigation into biodegradable alternatives.

Extraction, identification, and environmental risk assessment of microplastics in commercial toothpaste
Microplastics were extracted from ten commercial toothpaste brands sold in India and characterized by size and polymer type, with polyethylene being the most common material found. The study identifies toothpaste as a source of microplastic exposure through oral ingestion and wastewater discharge, adding to evidence on personal care products as plastic pollution sources.
Microplastic content of over-the-counter toothpastes from India: an in-vitro study
Researchers analyzed 20 popular over-the-counter toothpastes from the Indian market and found microplastic compounds present in all samples. Using infrared spectroscopy, they identified polyamides, polyethylene, and polypropylene across all tested brands, highlighting a potential daily exposure route to microplastics through routine oral hygiene products.
Occurrence and risk assessment of microplastics from various toothpastes
Researchers found microplastic particles in multiple commercial toothpaste products and conducted risk assessments, determining that microbeads and other plastic additives in toothpastes represent a source of microplastic release to aquatic environments and potential human oral exposure.
Microplastic content of over-the-counter toothpastes - a systematic review
This systematic review confirms that microplastic particles are present in many common toothpaste brands, including polyethylene and polypropylene beads used as abrasives. Since toothpaste is used daily and can be swallowed, this represents a direct and repeated route of microplastic exposure for consumers.
Synthetic polymers in personal care and cosmetics products (PCCPs) as a source of microplastic (MP) pollution
A market survey and consumer questionnaire study in Sri Lanka identified toothpaste as the personal care product with the highest content of synthetic polymer microplastics, and found that consumer awareness of MPs in cosmetics was low. The authors estimated substantial theoretical emissions of primary MPs from personal care products into the environment based on per-product polymer content.
