  • In the same year (2019), the Netherlands Food and Consumer Product Safety Authority (NVWA) also delivered an opinion on possible health effects of food additive titanium dioxide, which highlighted the importance of examining immunotoxicological effects in addition to potential reprotoxicological effects.

  • Traditionally, UV-filters are categorized as either chemical or physical. The big difference is supposed to be that chemical agents absorb UV-light while physical agents reflect it like a bunch of mini umbrellas on top of the skin. While this categorization is easy and logical it turns out it's not true. A recent, 2016 study shows that inorganic sunscreens work mostly by absorption, just like chemical filters, and only a little bit by reflection (they do reflect the light in the visible spectrum, but mostly absorb in the UV spectrum).

  • In the meantime, the chemical factories of Continental Europe, principally in Germany, Austria and Belgium, had taken hold of the novelty and under the collective name of lithopone or lithophone, by numerous processes, produced various grades of the pigment, branding the respective qualities as red seal, green seal, yellow seal, blue seal, etc., or selling them under some fancy name. Of this we shall speak later on. The crusade against the use of white lead in the various countries of Continental Europe, assisted the manufacturers, to a very great extent, in marketing their products, not only to industrial concerns, as has been the case in this country, until recently, but to the general painting trade. Up to 1889 the imports into this country were comparatively small. At that time one of the largest concerns manufacturing oilcloth and linoleum in the State of New Jersey began to import and use Charlton white. Shortly after that other oilcloth manufacturers followed suit, replacing zinc white with lithopone in the making of white tablecloth, etc., and later on abandoning the use of white lead in floor cloth and linoleum. This gave an impetus to several chemical concerns, that erected plants and began to manufacture the pigment. Competition among the manufacturers and the activity of the importers induced other industries to experiment with lithopone, and the shade cloth makers, who formerly used white lead chiefly, are now among the largest consumers. Makers of India rubber goods, implement makers and paint manufacturers are also consumers of great quantities, and the demand is very much on the increase, as the nature of the pigment is becoming better understood and its defects brought under control. Large quantities find their way into floor paints, machinery paints, implement paints and enamel paints, while the flat wall paints that have of late come into such extensive use owe their existence to the use of lithopone in their makeup.

  • When combined, mica and titanium dioxide in shampoo can create a synergistic effect, enhancing each other's benefits
  • Titanium dioxide R-5566, a rutile titanium dioxide pigment treated with zirconium and aluminum inorganic surface and organic surface, has the characteristics of high whiteness, high gloss, high achromatic power, high weather resistance, and good dispersibility.

  • Plastiques et caoutchouc : pour la pigmentation des élastomères naturels et synthétiques. Effets bénéfiques sur la résistance à la lumière et au vieillissement des produits en caoutchouc, amélioration des performances rhéologiques des mélanges de caoutchouc. L'abrasion et l'usure des outils de poinçonnage et de coupe, des calandres et des extrudeuses sont extrêmement faibles.
  • In conclusion, titanium dioxide is a versatile chemical that is widely used in the wholesale industry due to its excellent properties such as whiteness, opacity, UV protection, chemical stability, and eco-friendliness. As the demand for sustainable and high-performance products continues to grow, the use of titanium dioxide is likely to increase further in the future.

  • For this reason alone, its time to ditch the Titanium Dioxide & give your skin a break from the relentless free radical damage. 

  • 2. Addition of precipitants Various reagents such as sodium hydroxide, ammonia, or salts can be added to the titanium solution to induce precipitation.
  • The production of titanium dioxide powder has significant environmental impacts, primarily due to the energy-intensive nature of the chloride process
  • Manufacturers specializing in calcium compounds play a pivotal role in shaping the landscape of modern industry. Calcium, being a vital element for human health, finds its compounds used extensively in food supplements and dietary aids. Beyond the realm of health and wellness, these compounds are also crucial in environmental management, wastewater treatment, and as additives in agricultural fertilizers.
  • The most common type of titanium dioxide is known as rutile. Rutile titanium dioxide is known for its excellent durability and weather resistance, making it ideal for outdoor applications such as paints and coatings. It also has a high refractive index, which means it is very effective at scattering and reflecting light, making it a popular choice for use in cosmetics and sunscreens.
  • R996 is a high-performance rutile titanium dioxide widely used in the paint and coating industry for its exceptional durability and resistance to chemicals and weathering. Its excellent gloss retention and color stability make it a preferred choice for high-end applications where quality and longevity are essential. Additionally, R996 offers good dispersibility and compatibility with other ingredients, making it an easy-to-use option for formulators.
  • Titanium dioxide, represented by its chemical formula TiO2, is a white inorganic compound widely recognized for its broad range of applications. This oxide of titanium is not only the most common form of titanium but also one of the most abundantly found compounds in the earth's crust. Its unique properties have made it an indispensable material in various industries, from pigments to advanced materials science.
