Description

The present invention relates to a concentrated liquid body cleaner composition, and in particular, a concentrated liquid body cleaner composition having good fluidity, good low-temperature stability, and excellent foaming power and foam quality. About. In the present invention, the “concentrated type” is defined as one having a surfactant concentration of 30% or more in the cleaning composition. Accordingly, the concentrated liquid body cleaner composition has a surfactant concentration of 30% or more in the liquid body cleaner composition.

Today, as consumers are becoming more aware of the environment, it is important to be compact in detergents for clothing, kitchen detergents, etc., which gives great benefits to consumers and distributors. ing. For example, in laundry detergents, increasing the concentration of the composition, reducing the amount of cleaning agent used at one time, and reducing the size of the container contributes to saving space, reducing transportation costs, and reducing waste. doing. Recently, the concentration of the composition has been performed also in the kitchen detergent, and there is a product in which the container is made compact. Many surfactants blended in conventional compact type detergent compositions have been developed mainly based on anionic surfactants because of their excellent cleaning action.

On the other hand, with detergents such as shampoos and body shampoos in the cosmetics / cosmetics field, liquids from between the fingers when picked up in addition to the necessary items for use such as foaming, ease of rinsing, and non-irritation. It is necessary to have an appropriate viscosity and fluidity such that it is difficult to spill and is easy to apply on the hair and skin and to be easily refilled. However, in the development of concentrated detergents, for example, if an undiluted solution is concentrated as it is, the conventional technique has a high concentration of surfactant during concentration, and thus the shape is almost a gel, paste, or solid. In particular, fatty acid salts are currently most widely used as anionic surfactants excellent in cost and detergency, but have drawbacks when used as concentrated liquid detergents.

In general, it is known that the high viscosity of the fatty acid salt causes a significant increase in the viscosity of the composition such as thickening and gelling, and it is known that there is a problem in maintaining the liquid composition, for example, When the viscosity of the composition, such as thickening or gelation, increases significantly due to the high blending of fatty acid salts, it may not be discharged from the pump, resulting in disadvantages such as impaired usability and poor low-temperature stability. It was difficult to concentrate, and it was in a situation where a preferred form of the concentrated detergent composition was not possible.

Therefore, in order to solve the above problems, liquid detergent compositions are known in the clothing and kitchen detergent field, which are concentrated, but have fluidity and good low-temperature stability. For example, by combining a specific polymer compound and an alkoxy-type nonionic surfactant, a high concentration surfactant that maintains storage stability and does not degrade solubility due to gelation when diluted with water. A specific amount of a liquid detergent composition for clothes (for example, see Patent Document 1), a secondary alcohol alkoxylate, and an organic solvent having a solubility parameter of 14 or more and less than 23.50. Thus, a concentrated liquid detergent composition (e.g., a patent) having a coating detergency and stability that suppresses the occurrence of precipitation, gelation, etc., and is suitably used as a detergent composition for clothing. Reference 2) is disclosed. However, any liquid detergent composition has insufficient foaming power to be used as a concentrated detergent for skin washing. On the other hand, a liquid body cleaner composition having a high concentration and excellent low-temperature stability, which is a combination of a higher fatty acid potassium salt having a specific fatty acid composition and a free fatty acid in a specific ratio (see, for example, Patent Document 3). In addition, a detergent composition (see, for example, Patent Document 4) that can maintain fluidity at room temperature based on a fatty acid salt having 12 or more carbon atoms as a main component has been shown. It was not satisfactory enough.

Against this background, there has been a strong demand for the development of a concentrated liquid body cleaner that is easy to concentrate, has good fluidity, good low-temperature stability, and excellent foaming power and foam quality.
