JP5642429B2 - Cleaning disinfectant composition - Google Patents

Description

  The present invention relates to a cleaning disinfectant composition mainly used for cleaning and disinfecting floors, walls, appliances, and facilities of food factories and the like.

  In kitchen detergents for general households, neutral detergents based on anionic surfactants with high detergency are generally used because detergency against oil stains attached to tableware is important. .

  On the other hand, it is necessary to sterilize in addition to washing equipment and equipment at sites that handle food, such as food manufacturing factories, kitchens in restaurants, and processing workshops in supermarkets. Cationic surfactants such as benzalkonium and didecyldimethylammonium chloride are used.

  In addition, a cleaning disinfectant that combines a cationic surfactant with a nonionic surfactant or an amphoteric surfactant to perform cleaning and disinfection at the same time is also known.

  However, although cationic surfactants have sterilizing power, they have insufficient detergency, and when combined with an anionic surfactant that excels in detergency, separation and white turbidity occur, and the sterilizing effect and cleaning effect are significantly reduced. Therefore, washing and sterilization had to be performed in two steps.

  In order to solve such problems, a cleaning disinfectant for the purpose of simultaneously performing cleaning and disinfection has been proposed.

  Patent Document 1 proposes a liquid laundry detergent composition containing an anionic surfactant, a cationic surfactant, a nonionic surfactant, an alkali metal benzoate and water in a specific ratio.

  In Patent Document 2, an anionic surfactant (b) and a cationic surfactant (c) are added to water or a liquid (a) composed of water and a water-soluble solvent, and a solubilizer ( Liquid detergent compositions containing solubilized solutions obtained by stirring in the presence of d) have been proposed.

  Patent Document 3 includes a cationic fungicide made of benzalkonium hexadecyl phosphate, a metal chelating agent 0.5 to 5 times the mole of the fungicide, a nonionic surfactant and / or an amphoteric surfactant, Bactericidal disinfectant cleaning compositions containing anionic surfactants have been proposed.

  Patent Document 4 proposes a bactericidal composition containing a specific dialkyldimethylammonium salt, an anionic surfactant and / or an amphoteric surfactant.

  Patent Document 5 discloses (A) at least one anionic surfactant selected from alkyl sulfates and alkane sulfonates, (B) (b1) long-chain alkyldishort-chain alkylhydroxyethylammonium salts, and (b2) long A cationic surfactant composed of at least one cationic surfactant other than a chain alkyldishort chain alkylhydroxyethylammonium salt, (C) a sequestering agent and (D) water, and (A) in the composition A liquid sterilizing detergent composition characterized in that the mass ratio of (b1) is (A) :( b1) = 1: 2 to 1: 7 has been proposed.

  However, even with the above proposal, sufficient effects have not been obtained in both the cleaning effect and the sterilization effect. In particular, in terms of detergency, it was inferior to a neutral detergent mainly composed of an anionic surfactant, and it was difficult to say sufficient detergency. In addition, these cleaning disinfectants are used in order to suppress a decrease in disinfection effect due to the combined use of a cationic surfactant and an anionic surfactant, so that alkali metal benzoates, solubilizers, metal chelating agents, amphoteric Since the surfactant was added, there were problems in terms of mixing property, biodegradability and cost.
