Dióxido De Titanio
Dióxido De Titanio Uses, Dosage, Side Effects, Food Interaction and all others data.
Dióxido De Titanio, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium. It is used as a pigment under the names titanium white, Pigment White 6 (PW6), or CI 77891. It is typically extracted from ilmenite, rutile and anatase.

| Protein binding | The researchers/ determined blood levels of titanium dioxide (anatase) following oral ingestion of titanium-dioxide capsules and/or powder in six adult men (24-66 years of age). Titanium dioxide was absorbed by the gastrointestinal tract in a size dependent manner: smaller particles (0.16 um) were more readily absorbed than larger ones (0.38 um). Before the experiment, the background blood levels of titanium dioxide in these men ranged from approximately 6 to 18 ug/L. Blood levels reached up to approximately 50 ug/L or 100 ug/L between 4 and 12 hours after intake of 23 mg or 46 mg titanium dioxide, respectively |

Uses
Dióxido De Titanio is a sunscreen agent found in sunscreens that absorbs UV rays.
Dióxido De Titanio is used in most sunscreens to block UVA and UVB rays, similar to zinc oxide.
Dióxido De Titanio is also used to associated treatment for these conditions: Blisters, Dermatitis, Eczematous, Sunburn, Wounds, Abrasions, Dry, cracked skin, UV protection therapy
How Dióxido De Titanio works
Diminish the penetration of ultraviolet (UV) light through the epidermis by absorbing UV radiation within a specific wavelength range. The amount and wavelength of UV radiation absorbed are affected by the molecular structure of the sunscreen agent.
Toxicity
Rat - LD50 Intratracheal (>100ug/kg ) Effects: Structural or functional changes in bronchi and trachea. There is inadequate evidence in humans for the carcinogenicity of titanium dioxide. Cancer in experimental animals: There is sufficient evidence in experimental animals for the carcinogenicity of titanium dioxide. Overall evaluation: Dióxido De Titanio is possibly carcinogenic to humans (Group 2B).
Food Interaction
No interactions found.Volume of Distribution
Six hours after titanium dioxide was administered to rats through IV injection at 250 mg/kg body weight, the highest concentration appeared in the liver; after 24 hours, the highest concentration was detected in the celiac lymph nodes, which filter the lymph from the liver.
Elimination Route
When male and female rats were fed a diet containing titanium dioxide (100 g/kg) for a period of about 32 days, a significant retention of titanium of 0.06 and 0.11 mg/kg wet weight was found only in the muscles; no retention was observed in the liver, spleen, kidney, bone, plasma, or erythrocytes
Half Life
The kinetics of TiO2 elimination in the rat lung following its deposition after 7 hr exposure at 10 and 50 mg/cu m were determined for periods up to 140 days...The retention half-time was 14 days for the first clearance phase and 88 days thereafter.
Clearance
The clearance of titanium dioxide from the lungs was studied in rats after inhalation of 15 or 100 mg/cu m. The average median aerodynamic diameter of the titanium dioxide particles was 1.48 um. After a single exposure, about 40-45% of the deposited particles were cleared from the lung in 25 days. At 15 mg/cu m, 0.7% was found in the hilar lymph nodes indicating penetration of titanium dioxide particles from alveoli into the lymphatic system and partial clearance by the lymphatic route. The clearance rate was similar after intra-tracheal administration of titanium dioxide. At an exposure of 100 mg/cu m, the clearance rate decreased drastically. /Other researchers/ demonstrated the presence of titanium dioxide in the lymphatic systems of 3 workers employed in processing titanium dioxide pigments.
Elimination Route
