Bismuth Oxychloride, an Integral Part of the Cosmetics & Personal Care, Automotive, and Pharmaceutical Industries

 

Bismuth Oxychloride

Bismuth oxychloride (also referred to as the pearl white) is a natural inorganic compound of bismuth with the name BiOCl. It is a lustrous white solid used extensively since antiquity, especially in ancient Egypt. Bismuth oxychloride is a member of the boron family of elements and a member of the thio family of minerals. The compound's crystal structure is influenced by the iron-containing elements manganese and phosphorus. It is used as a color additive in various products such as automotive paints, printing inks, coatings, and drugs.

Bismuth oxychloride is used in various end-use industries, such as automotive, pharmaceutical, and cosmetics & personal care industries. Thus, the growth of these industries is expected to increase the demand for bismuth oxychloride in the near future. For instance, the United States is the world’s second-largest market for vehicle sales and production. According to SelectUSA, in 2018, U.S. light vehicle sales reached 17 million units, the fourth straight year in which sales reached or surpassed 17 million units. Bismuth oxychloride imparts a white color to cosmetics and personal care products.

Bismuth oxychloride is often used in topical skin applications. However, it has shown very low toxicity in animal tests so it's considered relatively safe. In clinical trials conducted on animals using this ingredient, there were no indications of irritation, redness, swelling, allergic, or digestive reactions. Although it is considered to be non-toxic, around 15 g can be tolerated by an adult, the long-term use of bismuth may result in side effects and even toxicity to human subjects.

However, because of its unique properties, the inorganic compound bismuth oxychloride was widely used as an antiseptic, particularly in ancient Egypt. Research has also shown that the compound is useful as an antifungal for fungal nail infections and nail dystrophy. There is also evidence that the compound is useful for treating athlete's foot, staphylococcus aureus, and candida infection (yeast). Bismuth oxychloride, which is made from bismuth itself, is believed to have antimicrobial activity. For this reason, it's been used for treatment of skin disorders including psoriasis, eczema, and nail infections such as onychomycosis.

Bell shaped pepper is a member of the Capsicum Baccatum species, which includes the Ají pepper

Image
  Bell pepper is the normal name for a cultivar gathering of the species Capsicum annuum, generally developed for their consumable, bell-shaped natural products, which are described by a polished outside of various shadings, including red, yellow, green, and orange. Bell peppers are now and then gathered with less impactful pepper assortments of Capsicum annuum known as "sweet peppers." There additionally are assortments of C. annuum that are impactful or hot, like the cayenne and jalapeño peppers. Bell shaped peppers contain a latent quality that disposes of capsaisin, the alkaloid that causes "hotness" in different plants in the family Capsicum. With their perfectly shaped structure and strikingly shaded outside of assorted shadings, bell peppers have been classified "the Christmas decorations of the vegetable world," to which is added a crunchy surface and tart taste (GMF 2008). Expanding on the variety in nature, bell shaped peppers mirror the notew...

Light Linear Alpha Olefins Are Produces through Oligomerization of Ethylene and by Fischer-Tropsch Synthesis

Image
  Light linear alpha olefins are commonly manufactured by two main routes: oligomerization of ethylene and by Fischer-Tropsch synthesis followed by purification. They are manufactured for a variety of reasons. One such reason is to use them as fabric and other textile applications in clothing manufacture. Various companies use ethylene trimerization process that produces only 1-hexene. In the U.S., Chevron Phillips Chemical Company, LLC, uses this process. Another commercial process, offered by a technology licensor IFP, dimerizes ethylene to high purity 1-butene. There are a wide range of applications for light linear alpha olefins . They are predominantly use in production of polyethylene, linear aldehyde, fatty acids, linear alcohols. Alpha olefins are also used in production of synthetic lubricant basestock and to make surfactants in a blend with higher linear alpha olefins. Another common use of light linear alpha olefins includes printing and apparel industries, agricul...

How is Tissue Banking Beneficial to People with Severe Morbidity, Chronic Diseases, and Organ Transplant Surgery?

Image
  Tissue banking alludes to the movement of gathering, stockpiling, handling, and circulation of transplantable human tissues. This industry fills in as a store of disposed of tissue and organs, both legitimately and wrongfully. These organs are here and there taken from criminal bodies or the dead groups of lawbreakers. Some of the time they may come from individuals who kick the bucket in emergency clinics. Whatever they are, every one of the organs are normally taken to a focal tissue bank which at that point discards them as indicated by neighborhood enactment. This interaction of collecting organs happens both when passing. There are numerous elements that decide when organs come from dead bodies. The fundamental one is that the organ must be dead and not yet deteriorating. Numerous organs must be eliminated from individuals who have passed on of sicknesses and ailments as these organs are not, at this point valuable. Some are even too harmed to possibly be helpful any longe...
