Application of Microplastics in Toiletry Products
AI summary Read the abstract
Researchers examined the use of microplastics in toiletry and personal care products such as exfoliants and toothpastes, assessing how these intentionally added particles enter waterways and accumulate in aquatic environments after passing through wastewater treatment systems.
Small plastic particles (microplastic: less than 5 mm) have gained significant attention in recent years due to their widespread presence in various environmental compartments and potential adverse effects on ecosystems and human health. One area where microplastics...

Microplastics in Personal Care Products and Cosmetics
AI summary Read the abstract
This review documented the types and quantities of microplastics deliberately added to personal care and cosmetic products — including microbeads in exfoliants, glitter in makeup, and plastic-encapsulated fragrances — and traced their path from consumer drains through wastewater treatment to aquatic environments. Personal care products represent one of the most direct routes of purposeful microplastic introduction into water systems and onto human skin and mucous membranes, making regulatory bans on intentionally added microplastics an immediately actionable health and environmental intervention.

Identification, characterisation and implication of releasing microplastics from personal care and cosmetic products in India
AI summary Read the abstract
Analysis of ten personal care and cosmetic products sold in India—including toothpaste, face scrubs, and eyeliner—confirmed the presence of polyethylene microplastics in nearly all samples, with additional traces of PVC and PET detected by FTIR spectroscopy. These findings highlight that everyday consumer products are a direct primary source of microplastic release into wastewater, contributing to broader environmental and human exposure.
Microplastics: An Overview
AI summary Read the abstract
This overview summarized the sources, types, distribution, environmental fate, and ecological effects of microplastics across aquatic and terrestrial systems, covering both primary and secondary plastic fragments smaller than 5 mm. The global ubiquity of microplastics — found in every environmental compartment — means human exposure through food, water, and air is effectively unavoidable without systemic intervention.
The Microplastics Issue
AI summary Read the abstract
This book chapter introduces the microplastics issue in the context of titanium and titanium nanoparticles, covering the size range and basic characteristics of microplastic particles (1–5,000 µm). The association of titanium-based nanoparticles with microplastic matrices is relevant to understanding how engineered nanomaterials may co-contaminate environments alongside plastic pollution.
