I'm sorry, but I couldn't find any information on "exoline yarn," which suggests it might not be a widely recognized term or product in the fields of textiles or yarn manufacturing as of my last update. The term might be a brand-specific product, a niche or newly introduced type of yarn, or possibly a typographical error. In the world of yarn, there are various types categorized by their material (such as cotton, wool, silk, or synthetic fibers), thickness, stretchability, and special features (such as water resistance, elasticity, or hypoallergenic properties). If you're looking for a specific type of yarn for a project, it's essential to consider these factors. For specialized or innovative yarns, it could be beneficial to investigate current industry trends or directly consult with manufacturers or specialty craft stores.

Titanium dioxide is generally considered safe for use in food, cosmetic, and sunscreen products by the FDA. However, there have been some concerns raised about its safety when inhaled in significant amounts over a long period, such as in occupational exposure scenarios. The International Agency for Research on Cancer designated inhaled titanium dioxide as a possible human carcinogen based on animal studies, but admits evidence is limited. Therefore, moderate use is likely not harmful, but continuous inhalation might be. Always use products as directed to ensure safety.
