Sunscreen Titanium Dioxide-Where Can I Buy Titanium Dioxide Powder
Titanium dioxide powder is a common pigment used in a variety of products, including paint, sunscreen, and even food. It can typically be purchased from several types of suppliers:
1. **Chemical Supply Companies**: Companies that specialize in selling chemicals for industrial, research, and educational purposes often carry titanium dioxide. Some well-known suppliers include Sigma-Aldrich (now part of Merck), Fisher Scientific, and Spectrum Chemical.
2. **Paint and Hardware Stores**: Some paint stores may sell titanium dioxide as a pigment for paint mixing, although it may not be in powder form but rather pre-mixed in a liquid medium.
3. **Art Supply Stores**: Titanium dioxide is also used as a white pigment in art materials, so art supply stores may sell it in a fine powder form suitable for use in油画, acrylics, and other art applications.
4. **Online Retailers**: Websites like Amazon, eBay, and Alibaba may have listings for titanium dioxide powder. When buying online, ensure that the seller is reputable and that the product is suitable for your intended use.
5. **Specialty Cosmetic Suppliers**: For those looking to use titanium dioxide in homemade skincare or makeup products, there are suppliers that specialize in raw materials for these purposes.
6. **Industrial Suppliers**: If you’re looking to purchase large quantities of titanium dioxide for industrial applications, you might need to contact suppliers that deal in bulk quantities.
Before purchasing, consider the following:
– **Purity**: Ensure the titanium dioxide is the appropriate grade for your needs (e.g., industrial, food grade, or pharmaceutical grade).
– **Regulations**: Be aware of any regulations regarding the use of titanium dioxide in your country, especially if it’s for use in products that come into contact with the skin or are ingested.
– **Safety**: Handle titanium dioxide powder with care, as inhaling the dust can be harmful. Always use appropriate personal protective equipment (PPE) like gloves and a mask when handling fine powders.
Remember to follow all local laws and regulations regarding the purchase, handling, and use of chemicals.
