Titanium dioxide

How much do you know about titanium dioxide?

What is titanium dioxide:

Titanium dioxide, a Inorganic compound with chemical formula of TiO2, is a white solid or powder amphoteric oxide, which has non-toxic, the best opacity, the best whiteness and brightness, and is considered to be a white pigment with the best performance in the world today. Titanium dioxide has strong adhesion and is not prone to chemical changes, making it always snow-white. There are three allotropes of titanium dioxide in nature: Rutile type, anatase type and plate titanium type.

Application :

Industrial applications:

Titanium dioxide is an important white pigment and porcelain glaze. Used in industries such as paint, ink, plastic, rubber, papermaking, chemical fiber, watercolor pigments, etc.

The best pigment for white paint made of titanium dioxide. The amount of titanium dioxide used as a pigment in the world can reach several hundred thousand tons per year. Titanium dioxide can be added to paper to make it white and opaque. In the rubber industry, titanium dioxide is also used as a filler for white rubber.

The photochemical properties of semiconductor titanium dioxide have made it suitable for many fields, such as the purification of air, water, and fluids.

Titanium dioxide has excellent UV light shielding and transparency. It is widely used in cosmetics, wood protection, food packaging plastics, durable household films, artificial and natural fibers, and transparent coatings. The special optical effect in metal flash coatings has attracted attention and application in high-end car coatings.

Food applications:

Titanium dioxide can be used as food white pigment, and the products are suitable for jelly, fried food, cocoa products, chocolate, chocolate products, hard candy, polishing candy, gum based candy, puffed food, candy chocolate product coating, Mayonnaise, Salad dressing, jam, solid drinks, konjac gel food, etc.

Electronic applications:

Titanium dioxide can be used to manufacture electronic materials, such as solar cells and capacitors. In addition, titanium dioxide has other applications, such as environmental protection, paper, and cellulose products.

Cosmetic applications:

Titanium dioxide can be used as a white pigment in cosmetics, such as foundation make-up and sunscreen.

Is adding titanium dioxide to cosmetics harmful to the skin?

Titanium dioxide generally does not pose any significant harm to the human body. A small amount of inhalation does not cause discomfort to the body. Titanium dioxide has non-toxic properties and optimal opacity. Features such as optimal whiteness and brightness. It has strong adhesion and is not prone to chemical changes.

The cream lotion containing titanium dioxide that we use daily is almost impossible to be inhaled into the lungs, so the skin care products we use daily can be used with confidence.

Secondly, it is the safety of applying titanium dioxide on the skin. In our daily cosmetics, we usually use nanoscale titanium dioxide after surface treatment, which is wrapped with a protective film on the surface of titanium dioxide to avoid direct contact between titanium dioxide and ultraviolet light, passivate its photocatalytic activity, and effectively inhibit its photocatalytic toxicity. So there’s no need to worry too much when using it.

As for the skin penetration of nanoscale titanium dioxide, nanoscale titanium dioxide may remain and accumulate in the Stratum corneum, but with the constant renewal and peeling of the Stratum corneum, titanium dioxide cannot accumulate in the skin for a long time.
