Description

  The present invention relates to a liquid detergent composition. In particular, the present invention relates to a liquid detergent composition suitable for textile products such as clothing.

  The liquid detergent composition containing hydrogen peroxide is advantageous in that it can be used for colored fabrics of textile products such as clothing, can be directly applied to dirt, and can be washed as it is. However, hydrogen peroxide can exert a high bleaching effect in a weakly alkaline aqueous solution, but the weakly alkaline solution reduces the stability of hydrogen peroxide, so a neutral to weakly alkaline general liquid detergent composition It is difficult to add hydrogen peroxide to the storage stability. Therefore, from the viewpoint of the stability of hydrogen peroxide, a composition in which the pH of the composition is made acidic at 3 or less and sacrificing detergency is common. Therefore, when used for clothing, an alkaline component is used. It was common to use it at the same time as a detergent or the like. In order to improve this, a liquid detergent composition that combines the stability of hydrogen peroxide and the cleaning effect by blending borate and polyol and increasing the pH at the time of dilution compared to before dilution is known. (See, for example, Patent Documents 1, 2, 3, and 4).

The liquid detergent composition containing hydrogen peroxide decomposes during storage to generate oxygen gas, although the pH of the composition is acidified to 3 or less to improve stability. For this reason, as the container for the liquid bleach, a thick, strong structure is usually employed. However, a liquid detergent composition containing hydrogen peroxide for refilling packed in a thinner plastic sachet has been demanded in order to save resources and reduce garbage. As such a refillable plastic bag-like packaging container, there are those disclosed in Patent Documents 5 and 6.
