Description

  The present invention not only has uniform and excellent detergency, but also does not easily evaporate or scatter when applied to griddles, ovens, fryer, etc. heated to high temperatures, and is excellent in safety and workability. The present invention relates to a liquid detergent composition that is excellent in stability and can be suitably used for cleaning carbonized dirt attached to cooking equipment that cooks at high temperatures such as griddles, ovens, and fryer.

  In cooking equipment that cooks at high temperatures such as griddles, ovens, fryer, etc., denatured or carbonized oil stains and food stains tend to adhere firmly to the surface. It took a lot of time and effort to work. For this reason, conventionally, detergents containing caustic alkali such as sodium hydroxide and potassium hydroxide have been used.

  As such a detergent composition, for example, a detergent composition containing an alkali metal hydroxide, triethanolamine, a polyhydric alcohol, an amphoteric surfactant and water and capable of washing carbonized oil stains is disclosed. (For example, refer to Patent Document 1). However, with a cleaning agent using caustic, it is necessary to pay particular attention to the handling work against scattering and splashing when applied to a griddle heated to a high temperature immediately after use. However, if cleaning is performed after the temperature of the objects to be cleaned such as griddles, ovens, and fryer is lowered to near room temperature, the pause time from the stop of use to the re-use is long. Inconveniences were likely to occur in restaurants.

  Therefore, in order to improve the scattering and evaporation of cleaning agents at high temperatures, it contains solid nonionic organic compounds and alkali metal hydroxides that are solid at normal temperature, and has excellent cleaning power and low skin irritation for high-temperature cooking iron plates An agent composition has been developed (see, for example, Patent Document 2). However, since a caustic alkali is contained in the cleaning composition, it is still necessary to pay attention to its handling, and further improvement in handling properties is desired. Further, in Patent Document 2, an appropriate shape such as a granular shape, a sheet shape, or a stick shape is proposed as the shape of the cleaning composition, but only the granular cleaning composition is disclosed in the examples. With such granular cleaning agents, it is difficult to spray the cleaning agent uniformly on the surface to be cleaned such as heated griddles and ovens, and the cleaning effect tends to be uneven, and it can be sprayed because it is not in liquid form. There is a limitation in use that it cannot be applied to walls and the like, and it is not easy to use. On the other hand, a liquid cleaning agent can be easily applied evenly to heated griddles and ovens, and can be applied to a wall surface. Is preferred.

  For this reason, in the case of liquid cleaning agents, in order to improve handleability, a cleaning composition having an excellent detergency using an inorganic alkali salt instead of caustic has been developed.

  Such a liquid detergent composition using an inorganic alkali salt is composed of, for example, a food additive-designated surfactant, a food additive-designated solvent, and a food additive-designated inorganic alkali salt. High range and oven cleaning compositions are disclosed (see, for example, Patent Document 3). However, when this detergent composition is applied to a griddle, oven, or fryer heated to a high temperature, it quickly evaporates, making it difficult to obtain sufficient detergency, leaving room for improvement.

  Also, as other detergent composition, it contains inorganic alkali salts, water-insoluble organic solvents, amines, pyrrolidone compounds, polyhydric alcohols, anionic surfactants and water, and has excellent detergency, safety and work A cleaning composition having improved properties is disclosed (for example, see Patent Document 4), and further, in a cleaning composition containing an inorganic alkali salt, a polyhydric alcohol and water, a thickener and a filler. Alternatively, a detergent composition containing a thickener as an additional component, having excellent detergency for carbonized oil stains, less likely to cause dripping at the time of washing, and having reduced smoke generation is disclosed (for example, , See Patent Document 5).

  However, these liquid detergent compositions containing the above inorganic alkali salts still have room for improvement in that they evaporate quickly when suitable for high-temperature griddles, ovens, flyers, and the like. Furthermore, they do not disclose quality aspects such as maintaining stable quality, particularly low temperature stability in winter. If it is suddenly applied to a hot griddle, oven, fryer, etc. with separation or precipitation occurring at low temperatures, the composition will become uneven and it will be difficult to obtain a uniform and excellent cleaning effect. Development of a liquid detergent composition having such a material is desired.
