Titanium dioxide is found in pretty much all makeup & sunscreen.

And studies have long shown that products applied to the skin end up in the bloodstream within half an hour. With penetration rates depending on where they are applied. Absorption rates for your face & scalp are 5-10 times higher than on other parts of our body (Hotchkiss 1994).

Not to mention that in 2005, the Environmental Working Group published a combination of two studies that found toxic chemicals in the umbilical cord blood of newborn babies born in the U.S. They screened for more than 400 chemicals, and an astounding 287 toxins were detected within the umbilical cord blood of these newborns. Of these 287 chemicals, 217 were neurotoxins, and 208 are known to damage growth development or cause birth defects.

From a stability standpoint, lithopone, a fusion of zinc sulfide and artificially precipitated barite, is non-toxic and exhibits resilience to mild lyes and acids. However, it is incompatible with colors containing copper. Despite its strong covering power in oil, lithopone’s drying capabilities are notably limited, posing potential issues for artists. Notably, early experimentation with lithopone-based grounds instead of zinc white resulted in undesirable darkening, although this blackness receded upon drying. This unpredictable behavior has sparked debate among scientific communities, emphasizing the need for further exploration and understanding of this pigment.

Titanium dioxide production is not without its environmental impacts. The traditional process involves mining rutile ore, which can lead to significant land disruption and potential pollution if not managed carefully. Moreover, the conversion of raw ore into usable TiO2 requires energy-intensive processes that contribute to carbon emissions. As such, consumers and manufacturers alike are increasingly seeking suppliers committed to sustainable practices.

  • One of the main reasons why an industrial leather sewing machine is essential lies in its capacity to sew thick materials. Unlike regular home sewing machines, which may struggle with heavy-duty fabrics, industrial machines are built with robust motors and reinforced components, allowing them to handle multiple layers of leather with ease. This durability results in cleaner, stronger seams that contribute to the overall strength and longevity of the final product.


  • 1. Multi-layer Capability One of the standout features of baffle sewing machines is their ability to handle multiple layers of fabric simultaneously. This is especially important in products like puff jackets and insulated bedding, where the insulation filling must be secured within baffles.


  • Cleaning
  • The regular sewing machine has been designed to sew together thinner fabrics, like clothes or bags. However, the thicker the fabric becomes, the harder the machine is forced to work. This means that regular machines might struggle to sew together more solid fabric items, like curtains. In this area, you will be better off purchasing a heavy-duty machine. Because their motor is more powerful, you will be able to get through these thicker materials without overworking your engine.
