From studies deemed relevant, the experts found that titanium dioxide as a food additive is poorly absorbed by the gastrointestinal tract of mice and rats, with no adverse effects observed in short-term studies in rodents receiving titanium dioxide in their diets. No observed adverse effect levels (NOAELs) of 15,000 milligrams per kilogram of bodyweight (mg/kg BW) per day and 5,000 mg/kg BW per day—the highest doses tested—were established for mice and rats, respectively.
1. Introduction
In 2017, the Scientific Committee on Consumer Safety (SCCS) warned that they should revise their recommendations if any new evidence emerges in the future related to the potentially harmful effects of TiO2NPs used in a sunscreen formulation or if they can penetrate the skin. In fact, our work could contribute to this matter because it evaluated the skin penetration of a particular kind of TiO2NPs. [8]

- Titanium dioxide is a widely used substance in the cosmetic industry, especially in China. It is a naturally occurring mineral that is used as a whitening and opacifying agent in many cosmetics, such as sunscreen, foundation, and face powder.
Most commonly used in candy, it can also be found in salad dressings, chewing gum, ice cream, frozen pizzas, drink and jello mixes and many other food categories. Titanium dioxide creates a smooth finish and adds shine and brightness to other colors.

- One of the leading manufacturers of titanium dioxide is RC 823, known for its high-quality products and innovative solutions. RC 823's titanium dioxide is widely used in the production of paints and coatings due to its excellent durability and color retention properties. The company is also known for its commitment to sustainability and environmental responsibility in its manufacturing processes.
- Titanium dioxide, commonly known as titanium white, is a versatile chemical compound with numerous applications in various industries. It is a naturally occurring mineral that is widely used as a pigment in paints, plastics, and coatings due to its excellent whiteness, opacity, and durability. In this article, we will explore the various uses of titanium dioxide and its significance as a wholesale ingredient.
- Titanium dioxide, a naturally occurring compound, is widely used in various consumer products due to its versatile properties. As an over-the-counter manufacturer, it plays a crucial role in the formulation of products that cater to the needs of consumers.
While IARC listed titanium dioxide as “possibly carcinogenic to humans,” they also add that “there is inadequate evidence in humans for the carcinogenicity of titanium dioxide.” Of the four human studies that they reviewed, only one showed a potential risk for occupational workers inhaling titanium dioxide particles and lung cancer, while the other three showed no risk for cancer at all. And it’s key to note that IARC did not assess the effects of titanium dioxide found in foods.
In the application of lithopone in ink industry, lithopone has fine particles, loose structure, good fineness and good paint adhesion, so it can be well combined with other colors in the composition of ink.
Even if you’re not familiar with titanium dioxide in makeup, it’s quite likely you’ve seen it in sunscreens, specifically physical formulas. Titanium dioxide is beloved in cosmetics not only for the pigment and coloration it can provide but also for the way it reacts to light.
