The present invention relates to a method for manufacturing an anti-scaling product intended for inhibiting the formation of scale in appliances in which elements such as pipes or tubes can suffer deterioration with use due to scale deposits. The method according to the invention makes it possible in particular to obtain an environmentally friendly anti-scaling product. Thus, the method according to the invention comprises a step of preparing (1) plant matter of the Caryophyllaceous family, a step of infusing (6) said plant matter, a step of filtering (7) said infusion, and a step of preparing (9) the anti-scaling solution from a filtrate obtained during the filtering step.
摘要:
A post chemical-mechanical-polishing (post-CMP) cleaning composition comprising: (A) is cysteine, glutathione, N-acetylcysteine, thiourea, (L) at least one oligomeric or polymeric polycarboxylic acid, and (C) water, wherein the post-CMP cleaning composition has a pH-value in the range of from 4 to not more than 7. The use of the composition for removing residues and contaminants from the surface of semiconductor substrates useful for manufacturing microelectronic devices. A process for manufacturing microelectronic devices from semiconductor substrates comprising the step of removing residues and contaminants from the surface of the semiconductor substrates by contacting them at least once with the post-CMP cleaning composition.
摘要:
In order to clean the paws of domestic animals, an agent is proposed, by which solid particles can be removed from the paws of domestic animals. Said agent consists of a highly viscous kneadable compound having a viscosity of 50000 - 150000 mPa.s, preferably 80 - 120 mPa.s. Said compound is formed by natural polygalactomanans and 75 to 95 % by weight of bound water and contains a disinfectant solvent from the group of saturated, monovalent alcohols. Preferably, the compound additionally contains re-lubricating, anti-inflammatory, disinfectant, aseptic and regenerating agents. The compound is made such that impurities can be kneaded in the compound by carrying out some kneading movements. The compound (3) is placed into a container (1) for use, which has a flat recess for receiving the cleaning agent for paws of domestic animals. The compound is protected from drying out by means of a cover (4), preferably a cover made of a soft plastic and covering the recess in a form-fitting manner.
摘要:
An alkaline concentrated detergent composition for use in cleaning hard surfaces, medical instruments and other metal components (parts, tools, utensils, vessels, equipment) having superior cleaning efficacy at much lower alkali content than traditional alkaline cleaners and enhanced scale control properties even when diluted to about 1/40 ounce per gallon to about 1/10 ounce per gallon in potable water and even in exceptionally hard water. The inventive composition maintains its superior cleaning efficacy and scale control properties during use.
摘要:
The present invention provides solutions containing dexpanthenol in combination with xylitol, preferably further including a viscosity-enhancing agent to make solutions viscous so that the viscous solutions are not only capable of cleaning, disinfecting, and/or rinsing a contact lens in a lens case but also capable of cleaning and lubricating the contact lens directly in an eye. Such solutions can provide to the user an ability to clean and to rewet lenses anytime anywhere even without taking them out.
摘要:
The invention relates to an encapsulation system for a hydrophobic flavour or perfume ingredient or composition, capable of releasing said substance, usually crystalline at ambient temperature and pressure, in a non-crystalline form.
