Nanostructured bismuth materials have gained a lot of attention due to the quantum behavior of the material. They are also useful in power generators, thermoelectric coolers, and optical devices.
Bismuth oxide has also been found to be effective in biological applications. Bismuth based medical formulations are still used to treat stomach issues. Bismuth is also used in astringents, bacteriostatic agents, and refrigerants. It has also been used in nuclear industry as a refrigerant. It also serves as a substitute for lead in electrical equipment.
Bismuth has been used in a variety of applications since the 19th century. However, use of bismuth was slowed in the 20th century. This was due to reversible bismuth encephalopathy. However, there are still a number of established treatments that need new technologies.
Bismuth Oxide Powder Release to the environment
During the preparation of bismuth oxide powder, the process of heating and cooling is used. This process is done to produce the high-purity bismuth oxide powder.

Micro-Bi2O3 powder of controllable granularity
During the research for the present invention, we discovered that a micro-powder of controllable granularity of synthetic wax could be formulated into cosmetic compositions and skincare products. These powder compositions can be free flowing or pressed powder compositions, and can be applied to any part of the skin. They can also be used as body scrubs.
The granularity of the powder compositions can be controlled by varying the percentage of wax in the composition. More preferably, the wax powder is greater than 1.0% by weight and has an irregular shape.
The micro-powder of the present invention is comprised of a synthetic wax that has a non-uniform granular shape. This shape has a substantial effect on the fraction of light that is detected. The luminosity of the powder is derived from X-ray excited luminescence decay curves. The powder sample was compared to CsBa2I5:Eu samples with known luminosity.
In addition to the cosmetic compositions, the powder compositions of the present invention can also be formulated into a wide variety of other product types. These include, but are not limited to, creams, lotions, cream-based lotions, serums, serum-based lotions, face creams, lotion-based face creams, lip glosses, lip balms, lip scrubs, hand creams, foot creams, and a variety of other products.
The micro-powder of controllable shape of the present invention is more particularly suited to cosmetic compositions, skincare compositions, and body scrubs. It is also a valuable tool for scientists who need to evaluate the potential of a compound quickly. Compared to the time it takes to synthesize a single crystal, powders are fast to prepare. Powders are easier to apply and provide a better feel to the skin.
