Description

  The present invention relates to a liquid detergent composition.

  Making a product with less environmental impact by a method with less environmental impact is required for the sustainable development of society, and the detergent composition is no exception. Achieving industrial activities and living activities that harmonize with the environment, including the natural environment and social environment, and have a low burden will be the most important issue in the future. The surfactant used in the cleaning composition is not too sensitive to environmental impact. Conventionally, surfactants have often caused environmental pollution as a problem. However, considering the environmental load, it is important to consider all the effects from manufacturing to use and disposal. There are two types of surfactant raw materials: natural fats and oils. Natural fats and oils are reproducible resources, and petroleum is a non-reproducible resource that will eventually be exhausted. From the viewpoint of reproducible resources, natural fat and oil-based raw materials are attracting attention.

  In addition, from the viewpoint of environmental impact, a small amount of highly functional (high detergency) products are required. This also leads to a reduction in environmental load in terms of reducing packaging materials and transportation load.

  One method for obtaining a detergent with a small amount and high detergency is to increase the concentration of the surfactant. In general, a high-concentration surfactant solution is easily affected by temperature. Depending on the viscosity, the viscosity may change, and even if it is stable at room temperature, crystals may precipitate or freeze at low temperatures. For this reason, in order to maintain liquid stability, glycols such as ethylene glycol, propylene glycol, and polyethylene glycol, lower alcohols such as methanol and ethanol, toluene sulfonates, xylene sulfonates, etc. themselves are not so washed. Since it is necessary to add a large amount of hydrotrope that does not show strength, it has been difficult to develop products that use a small amount (compact) of the liquid detergent composition.

On the other hand, a composition in which both hydrogen peroxide stability and cleaning performance are achieved by a technique (pH jump technique) in which hydrogen peroxide is blended and diluted with water at the time of use is known (pH jump technique) ( Patent Literatures 1 to 3).
