General process information Detergents are manufactured using a synthetic surfactant in place of the metal fatty acid salts that are used in soaps. Most of the powder detergents have soap in their mixture of ingredients‚ however it generally functions more as a foam depressant than as a surfactant. Powder detergents are manufactured using various processes‚ such as spray drying‚ agglomeration‚ dry mixing or a combination of these. Spray Drying Process The different stages / operations performed

DCITATION: http://www.epa.gov/dfe/pubs/laundry/techfact/keychar.htm Surfactants * Positive Environmental Characteristic: Biodegrade readily to compounds with low toxicity. Example: Straight carbon chain compounds like linear alcohol ethoxylates or betaine esters. * Key Characteristics of Concern: Toxicity to aquatic organisms‚ like fish (vertebrates)‚ daphnids (invertebrates) and algae; persistence in the environment; toxicity of biodegradation byproducts. * Example: Alkylphenol ethoxylates--biodegrade

The effect of temperature on beet cell membranes Introduction: A cell membrane of a beet (Beta Vulgaris) is made up of a phospholipid bilayer with embedded proteins and cholesterols. The membrane is responsible for organizing the cell‚ protecting it from the exterior environment‚ as well as responsible for regulating what goes in and out of the cell though it’s protein channels and “selectively permeable” bilayer. (Campbell‚ Reece‚ Taylor & Simon‚ 2006‚ p. 79-80) When this membrane is damaged

Natural Benefits of Drinking Beet Juice: Drinking beet juice can lower blood pressure levels in just a few hours. One study found that drinking one glass of beet juice lowered participants’ blood pressure by an average of 4-5 points. This can be attributed to the naturally occurring nitrates in beets‚ which are converted to nitric oxide in the body. This then relaxes and dilates the blood vessels to improve blood flow and lower blood pressure. Many illnesses and chronic diseases begin with inflammation

Laundry detergents are found in every household and used for removing stains and oils from clothes so they could be reused. The production of this invention first started in the United States in the 1930s but started becoming very popular only after the Second World War because the military required a chemical to remove the dirt and oil off their military outfits (Clean Living). Laundry detergents have a combination of chemicals which combat different barriers to clean the fabric. They have different

structure. Beet cells‚ which are plant cells‚ have a water-soluble pigment called betacyanin‚ which is stored in its vacuole. The tonoplast‚ or the vacuole’s membrane‚ acts with the cell membrane of the cell to prevent the betacyanin from leaking into the cytosol or out of the cell. This lab investigates the environmental possibilities that can damage membranes. Hypertonic and hypotonic salt solutions place stress on cell membranes‚ detergents make lipids

corn syrup (referred to as Caliber)2. Beet juice is the by-product in the production molasses for sugar beets.3 The by-product is generally not processed further (depends on manufacturer) and commonly contains minute particles dispersed through-out liquid. As a result‚ beet juice based blends have a greater tendency to clog filters vs. caliber based blends.1 Performance Characteristics: Caliber possesses a significantly better eutectic point than that of beet juice. This translates to a greater

1. Antioxidant Compounds in Red Beet Excessive formation of free radicals such as reactive oxygen species (ROS) and reactive nitrogen species (RNS) occur as a byproduct of cellular metabolism. Free radical generation causes oxidative stress which has been associated with undesirable health effects (Valko et al.‚ 2007). Antioxidants are needed when ROS are generated inside the body‚ as the first line of defense (Lobo et al.‚ 2010). Halliwell & Gutteridge (2015) describe an antioxidant as “any substance
