Q titanium dioxide function in pharmaceuticals

ShirleyEdmund Release Time: 3月 21, 2024, 9:48 下午

Titanium Dioxide is widely used in pharmaceuticals as an excipient (inactive substance that serves as a vehicle or medium for a drug). It serves multiple functions: 1. Opacifying Agent: It is used to make round tablets for medicine white and opaque, providing a more pleasant appearance. 2. Coating: It is used as a coating on some tablets to make them smooth and easy to swallow. 3. Sunscreen and UV Absorber: In topical pharmaceuticals, it is used as a physical blocker to absorb or reflect UV light. 4. Agent for Delayed Release: Some oral medications use titanium dioxide in their coatings to control where and when in the digestive tract the medicine is released. 5. Photo-Stabilizing Agent: It protects drug products from alteration caused by the sunlight. 6. Catalysts: It is used as a photocatalyst for the photodegradation of pharmaceuticals and personal care products during water treatment. Contrary to its many uses, there’s controversy surrounding its use due to potential negative...

Q titanium dioxide hazard class

VernaI Release Time: 3月 21, 2024, 10:20 下午

Titanium Dioxide is classified as a Group 2B carcinogen by the International Agency for Research on Cancer (IARC). However, it is important to note that this classification is based on studies showing a potential risk of inhaling high concentrations of titanium dioxide dust, which can occur in occupational settings. In everyday use, such as in cosmetics or food, titanium dioxide is generally considered safe.

Q titanium dioxide high refractive index

CedricJuliet Release Time: 3月 21, 2024, 10:02 下午

The refractive index of titanium dioxide is relatively high, approximately 2.4. The index varies slightly depending on the specific form or crystalline structure of the material (it can exist as rutile, anatase, or brookite). The high refractive index makes titanium dioxide particularly useful in optical coatings and in creating pigments for paints, inks, and food colorings.

Q replacing titanium dioxide in beverage

EveHobbes Release Time: 3月 19, 2024, 5:56 下午

Replacing titanium dioxide in beverages can be accomplished in various ways. Titanium dioxide is often used in food and beverage production for its whitening and opacifying qualities. However, there have been health concerns regarding its use. 1. Use Natural Food Colorants: Companies can consider replacing titanium dioxide with natural food colorants. The color can be achieved with spices like turmeric or paprika, fruit or vegetable juice concentrates, etc. 2. Hydrocolloids: Some beverages may also benefit from the use of hydrocolloids, such as gellan gum or carrageenan, which can help provide a uniform dispersion of minerals and vitamins, avoiding the need for titanium dioxide. 3. Minerals: Other minerals, like calcium carbonate or silicon dioxide, can be used as alternatives. These options may offer similar effects but have different health considerations. 4. Use Nanotechnology: Some companies use nanotechnology to create nanoparticles of different substances that can mimic the appe...

Q what is blue zircon used for

VernaI Release Time: 3月 18, 2024, 9:08 下午

Blue zircon is primarily used as a gemstone in jewelry. Its vibrant blue color and high refractive index (which gives it a great brilliance) make it a popular choice for rings, earrings, and pendants. In addition, it is also sometimes used in various healing and spiritual practices, as it is believed to have certain metaphysical properties. However, its main use remains in the field of jewelry.

Q long term effects of titanium dioxide

RenataRoger Release Time: 3月 15, 2024, 6:34 下午

Long-term exposure to titanium dioxide, particularly in its nanoparticle form, may cause adverse health effects. Studies on rodents showed inhalation can lead to respiratory tract inflammation, lung damage and even cancer. Although it’s considered safe for topical use and in food, risks associated with inhalation or occupational exposure warrant further research. While it’s a commonly used pigment in consumer products, including sunscreens and food coloring, more investigation is needed about its long-term effects on human health. The International Agency for Research on Cancer classifies it as a Group 2B carcinogen, which means it’s “possibly carcinogenic to humans”.

Q can i wear white zircon and ruby together

VernaI Release Time: 3月 14, 2024, 6:23 下午

Yes, you can wear white zircon and ruby together. There’s no rule in gemology or jewelry that prevents the wearing or pairing of certain gemstones. Both stones are quite durable and would make beautiful pieces together. If you need more concrete advice, you could consult with a jeweler or a gemologist.

Q what is the empirical formula for zircon

VernaI Release Time: 3月 14, 2024, 5:43 下午

The chemical formula for zircon, a mineral, is ZrSiO4. This represents a compound made of zirconium (Zr), silicon (Si), and oxygen (O) in a ratio of 1:1:4. The empirical formula simplifies this ratio to its smallest whole number ratio, which remains the same as the molecular formula for zircon, indicating that it is already in its simplest form.
