L-leucine, also known as leucine, is α-amino-γ-methylvaleric acid, α-aminoisocaproic acid, and its molecular formula is C6H13O2N. L-leucine is one of the eight essential amino acids for the human body. It belongs to the aliphatic amino acids in the twenty protein amino acids. Together with L-isoleucine and L-valine, it is called the three major branched chain amino acids. It is an enantiomer with D-leucine, and it is a white glossy hexahedral crystal or a white crystalline powder at room temperature. Odorless, slightly bitter. In the presence of hydrocarbons, it is stable in aqueous mineral acid. Dissolve each gram in 40ml of water and about 100ml of acetic acid. Very slightly soluble in ethanol or ether, soluble in formic acid, dilute hydrochloric acid, alkaline hydroxide and carbonate solutions.

The nozzles of pressure washers are essential in controlling the strength and the pattern sprays that determine the efficiency of your cleaning chores. Many nozzles are available; each has a distinct function, ranging from gentle cleaning to heavy-duty dirt removal. The five most commonly used pressure washer nozzles tips are colored based on the angle of spray, which is Red (0deg) for focused, precise blasts, yellow (15deg) to strip tough dirt and dirt, green (25deg) for general cleaning, and white (40deg) for more delicate surfaces as well as black (65deg) to apply soap. Choosing the correct nozzle will dramatically improve your cleaning efficiency and prevent damage to surfaces. For instance, the 0deg nozzle provides the highest pressure but must be used cautiously, while the 40deg tip offers the broadest, softer spray suitable for windows or vehicles. To enhance the capabilities of your pressure washer, Turbo, and rotating nozzles offer additional cleaning power by combining high pressure and rotational action, which is perfect for tough debris. Selecting the right tip for your pressure washer ensures that you can match the strength of the spray to the surface, making each cleaning task more secure and effective.

Saccharin sodium, also known as o-sulfonylbenzimide sodium salt, usually contains two molecules of crystal water, which is colorless crystal and easily weathered to lose about half of the crystal water and become white powder. The sweetness is 200-500 times higher than that of sucrose, and its thermal stability in aqueous solution is better than that of saccharin. The sweetness of aqueous solution decreased slowly after long time storage. In terms of sweetness, the anions decomposed by saccharin sodium have strong sweetness, but there is no sweetness in the molecular state, and they are disgusted with bitterness. Saccharin sodium has high solubility and dissociation degree, so it is sweet.
