2. Machine Features The price can also vary greatly depending on the features included. Basic zigzag sewing machines might only offer the fundamental zigzag stitch, while more advanced models may come equipped with multiple stitch options, automatic threading, and digital displays. Machines with more features typically range at a higher price point but can offer greater convenience and versatility.

E. Garment Construction and Alterations:
We’ll provide project ideas for garment construction and alterations, such as sewing denim jeans, altering jackets, and creating durable workwear using heavy duty sewing machines.

- After sewing, you’ll want to finish the raw edges to prevent fraying. Techniques such as zigzag stitching or using a serger are effective ways to accomplish this.

Although it was initially designed for industrial use, nowadays, the heavy duty sewing machine has become a popular choice for home use, too. The sewing machine adds to the whole sewing experience, therefore experienced tailors around the world choose heavy duty sewing machines over the normal ones. But what is the best heavy duty sewing machine for home use?

Nanoparticles

On the other hand, the U.S. Food and Drug Administration (FDA) in their Final Administrative Order on Sunscreen Drug Products posted in September 2021 still accepts titanium dioxide up to 25% in the list of Generally Recognized As Safe and Effective (GRASE) in the main document, without further clarification on what kind or size of particles [9]. However, on page 24 (Sunscreen containing nanomaterials) FDA clearly “distinguish nanomaterials from other forms of these ingredients'' (zinc oxide and titanium dioxide) and ask for comments on “any particular nanomaterials that you believe should not be permitted for use in OTC sunscreen products”. To the best of our knowledge, this Agency did not ban the use of nanoparticulate titanium dioxide in any form, even though it is mentioned on page 34 that the anatase form is the more photoactive one, due to the lack of evidence with real sunscreens OTC (over the counter) in vivo. Moreover, other regulations in Latin America (MERCOSUR agreement, 2006) do not state clearly their position on the use of nanoparticulate TiO₂NPs [10].

While the FDA maintains that the regulated use of titanium dioxide is safe, the European Food Safety Authority and some other experts warn of potential, serious health risks.

No. EFSA’s role was limited to evaluating the risks linked to titanium dioxide as a food additive. This included an assessment of relevant scientific information on TiO₂, its potential toxicity, and estimates of human dietary exposure. Any legislative or regulatory decisions on the authorisations of food additives are the responsibility of the risk managers (i.e. European Commission and Member States).
