These chemicals are used to soften and stretch plastic products, but they can also be found cosmetically in nail polish, hair spray (to make them less stiff or brittle), and perfumes. Phthalates are made from oil. There are over 20 types of phthalates in everyday use. Because of their di...
These chemicals carry a charge that causes the fabric fibers to stand up, resulting in a soft, velvety feel rather than the crisp feel of cotton clothes dried in the sun. When cationic chemicals are used in softeners, they can do a double function, fluffing up the fabric as well as ...
Chemical precipitationis one of the more common methods used to soften water. Chemicals normally used are lime (calcium hydroxide, Ca(OH)2) and soda ash (sodium carbonate, Na2CO3). Lime is used to remove chemicals that cause carbonate hardness. ...
Phthalates are used commercially to soften plastics, make nail polish more adherent, and can be found in perfumes as well. But these chemicals are also known to interfere with hormone production, reduce sperm production, and cause birth defects. While this may be cause for concern, some experts...
Zeolites LTA are employed to soften water in an aspect of being as a charge exchanger instead of phosphate ions which is not friendly to the environment in detergent system [6]. In the aspect of adsorption, it is employed as an adsorbent of an ammonium ion in waste water and it is used...
What are the benefits of hyaluronic acid in serums and moisturisers? Hyaluronic acid is a humectant, an ingredient that draws water to itself. Put hyaluronic acid on your skin, and it will draw moisture out of the air and into the skin — unless the air around you is very dry, in whic...
The process involves covering all the floors and furniture with plastic and spraying the ceiling with water to soften the popcorn ceiling and then scraping it with a popcorn scraper that removes the texture and catches it in a bag (sort of). Even if you are extremely careful it’s easy to...
In chemistry laboratories many different types of chemicals are present. These chemicals are preserved in a bottle with the name of the chemical. Some common chemicals are HCl and NaOH. Answer and Explanation:1 HCl is hydrochloric acid. It is a strong acid. This acid is hazardous liquid ...
evidence of glue was found in the cave paintings of Neanderthals in Lascaux, France. The raw materials for the production of glue might be animal parts or fish. The manufacturing process of glue involves cooking the raw material in water and then adding chemicals to make the glue into various...
Standard solutions of calcium ion used to test for water hardness are prepared by dissolving pure calcium carbonate, CaCO3, in dilute hydrochloric acid. A 1.745-g sample of CaCO3 is placed in a 250.0-mL volumetric flask and dissolved in HCl. ...
