Description

  The present invention relates to a cleaning composition, and more particularly, to a liquid and gel cleaning composition that has an appropriate viscosity and is excellent in handleability and does not cause a decrease in viscosity over time.

  Various types of thickeners have been developed in liquid and gel detergent compositions for current hair shampoos, body shampoos and kitchens in order to improve their handling and use feeling. Appropriate blending provides the desired viscosity. It has also been reported that a further thickening effect can be obtained by combining these thickeners with fatty acids and salts (for example, Patent Documents 1 and 2).

  As one of various thickeners blended for such a purpose, there is a polymer thickener having a polyoxyalkylene chain in the molecule. Among them, polyoxyalkylene polyol fatty acid ester compounds such as polyoxyethylene polyglycerin fatty acid ester, polyoxyethylene sorbitol fatty acid ester, and polyoxyethylene pentaerythritol fatty acid ester are excellent in thickening performance and have a desired thickening effect with a small amount of compounding. It can be obtained (for example, Patent Documents 3, 4, and 5).

Examples of such alkylene oxides having 2 to 4 carbon atoms include ethylene oxide, propylene oxide, butylene oxide and the like.

  The fatty acid used in the polyoxyalkylene polyol fatty acid ester of the component (A) used in the embodiment of the present invention is a linear or branched fatty acid having 8 to 36 carbon atoms, and is used even when saturated or unsaturated. The ester group and the degree of esterification can be selected according to the target product viscosity. In the liquid and gel detergent composition of the present invention, it is preferable to blend stearic acid ester and ester compound of triester or higher.

  The polyoxyalkylene polyol fatty acid ester of the component (A) used in the embodiment of the present invention is 0.1 to 10.0 in the cleaning composition in consideration of the type of cleaning component used and the target viscosity. The mass is preferably 0.1% to 6.0% by mass. If it is less than 0.1% by mass, good viscosity cannot be obtained, and if it exceeds 6.0% by mass, the viscosity is excessively improved, which affects the feeling of use and the properties of the cleaning composition.

X: The formulation viscosity is lower than before the test.
It is shown by the two-stage evaluation.

  The evaluation results are shown in Table 13.

  In the cleaning composition of the present invention, as a result of comparing the prescription with no buffering agent and the prescription with a buffering agent, the formulation with the pH adjusted with the buffering agent has a significant viscosity improving effect even when the pH is initially adjusted. Moreover, it is possible to obtain an excellent formulation without being affected by the type of the buffer agent in terms of stability over time.

<Evaluation Example 10>
Next, the stability with time of the cleaning composition in each pH range adjusted by blending of the component (E) was evaluated.

For stability over time, compare the viscosity after 3 months in storage at 45 ° C with the viscosity before the test,
○: No decrease in viscosity is observed before the test.
X: The formulation viscosity is lower than before the test.
It is shown by the two-stage evaluation.

  The evaluation results are shown in Table 14.

  As a result of setting the amount of the component (A) to 0.8 mass% and adjusting the viscosity with the component (E), a large thickening effect can be obtained at a pH value of around 5.5, and each pH range Thus, it was possible to obtain a detergent composition having excellent stability over time.

Example 100: Transparent shampoo;
A transparent shampoo having the composition shown in Table 15 below was prepared as follows. That is, component 1 was heated to 70 ° C., component 2 was heated to 75 ° C., and component 1 was mixed while stirring component 2. This transparent shampoo exhibited excellent properties such as transparency and foaming and excellent stability over time (viscosity: 32600 mPa · s).

Example 101: Pearl shampoo (1);
A pearl shampoo having the composition shown in Table 16 below was prepared as follows. That is, component 1 was heated to 70 ° C. and component 2 was heated to 75 ° C., component 1 was mixed while stirring component 2, and then pearls were precipitated while stirring at 40 ° C. for 1 hour. This pearl shampoo had good pearly feeling and foaming, and exhibited excellent properties with stability over time (viscosity: 31500 mPa · s).

Example 102: Pearl shampoo (2);
A pearl shampoo having the composition shown in Table 17 below was prepared as follows. That is, Component 1 is heated to 70 ° C., Component 2 is heated to 75 ° C., and Component 1 is mixed while stirring Component 2. Then, it cooled to 40 degreeC and mixed the component C. This pearl shampoo can easily give a pearly feeling, has good foaming, and exhibits excellent stability over time (viscosity: 52900 mPa · s).

Example 103: Body shampoo;
A body shampoo having the composition shown in Table 18 below was prepared as follows. That is, component 1 and component 2 are heated to 70 ° C., and component 2 is mixed and saponified while stirring component 1. Thereafter, Component 3 was added, and pearls were precipitated while stirring at about 40 ° C. Since this body shampoo is mainly composed of fatty acid soap, it has very good foaming and has excellent refreshing and pearly properties (viscosity: 13120 mPa · s).

  The present invention relates to a cleaning composition, and more particularly, to a hair shampoo, body shampoo, facial cleanser, and kitchen or bathroom detergent.
