Description

  The present invention relates to a detergent composition for use in a dishwasher. In particular, the present invention relates to a detergent composition for use in a commercial dishwasher. The cleaning composition for a dishwasher according to the present invention reduces the water spot by accelerating the drying of dishes and glasses at the same time as removing dirt in the cleaning of tableware such as ceramics, glass and plastic without using a rinse agent. Enable.

  A dishwasher is a facility for washing dishes such as dirty dishes, glasses and cooking utensils, and is used in kitchens such as homes, restaurants and coffee shops. In general, dishwashing is performed in the order of washing process-rinsing process. In the washing process, a non-foaming or low-foaming dishwasher cleaner different from a dishwashing detergent for hand washing is used. In addition, a rinsing agent is used in the rinsing process for commercial dishwashers used in kitchens such as restaurants and coffee shops.

  Rinse agents are used to speed up the drying of dishes and reduce the appearance of white spots called water spots for a beautiful finish. The water spot is dried before water droplets adhering to the tableware surface flow down, and hardness components such as calcium, magnesium, and silica are deposited on the tableware surface. Especially in the case of glass tableware, the beauty is greatly impaired.

  Generally, nonionic surfactants such as glycerin fatty acid esters and sorbitan fatty acid esters are blended in the rinsing agent, and the rinse water is emulsified to lower the surface tension with the tableware and make it easy for water droplets to flow down. As a result, the drying of the tableware is accelerated, and the water spot can be reduced. Therefore, rinsing agents are used in restaurants and coffee shops where tableware is frequently used.

  However, although the rinsing agent has an effect of reducing the water spot, it is never satisfactory, and a restaurant or a coffee shop is wiping with a towel to remove the water spot attached to the tableware. Further, since the rinse agent is used in the rinsing process, a supply device different from the cleaning agent used in the cleaning process is required. Furthermore, it is necessary to purchase rinsing agents and inventory management costs, which is a big burden at restaurants and coffee shops.

Patent Document 1 contains a positively charged polymer, a water-soluble polymer that suppresses phosphate scale formation, and exhibits excellent cleaning effect and glass appearance even in the absence of sodium chloride or a rinse aid composition. A composition is disclosed. Patent Documents 2 and 3 disclose that a cationic or amphoteric polymer is used as a detergent for a dishwasher.
