Description

  The present invention relates to a transparent gel-like cleaning composition, and in particular, it is excellent in foaming, detergency, ease of rinsing, imparts a moderate moist feeling to the skin after use, and maintains its gel state even when stored at high or low temperatures The present invention relates to a clear and stable cleaning composition that can maintain the viscosity for a long time.

  Conventionally, skin cleansing materials are classified into solid, liquid, and paste (gel) in terms of appearance, and opaque and transparent ones have been developed. Among them, the transparent gel detergent composition has a unique high-class feeling, and is considered to have high commercial value and marketability.

  Known techniques for transparent gel composition detergents include combinations of surfactants such as alkyl sulfates and alkyl ether sulfates with polymers and swellable clay minerals. There is a problem that it is not preferred by consumers, especially Japanese. In addition, a transparent gel-like cleaning agent containing an amino acid-based surfactant as a main component is also known (see Patent Documents 1, 2, and 3). In addition, amino acid-based surfactants are expensive and are not suitable for use as general-purpose cleaning agents.

  Many transparent gel detergents using fatty acid salts which are inexpensive and safe raw materials have been proposed. Transparent gel detergents that use fatty acid salts are often poor in stability at low and high temperatures due to the high crafting point of fatty acids. And proposals have been made such as using fatty acid alkanolamide type nonionic surfactants, hydroxy polyhydric alcohol ether compounds, and the like (see Patent Documents 4, 5, 6, 7, 8, 9). On the other hand, the detergent composition mainly composed of fatty acid salt has a feeling of skin tingling and tingling as it dries after washing. As a method for reducing these, amphoteric surfactants and semipolar A technique of blending a surfactant is disclosed (see Patent Documents 10 and 11). In these documents, these problems are solved by blending a semipolar surfactant having a specific structure, but the combined use of amphoteric and semipolar surfactants is not limited to use, and the refreshing feeling peculiar to soap is impaired. Since it has a feeling, the feeling of slime is increased and it is not always satisfactory.

  In the above circumstances, the object of the present invention is excellent in foaming, detergency, and ease of rinsing, imparts a moderate moist feeling to the skin after use, and maintains its gel state for a long time even when stored at high or low temperatures. An object of the present invention is to provide a transparent gel-like cleaning composition that can be maintained and has excellent transparent stability.

  As a result of earnest research to achieve the object of the present invention, the present inventor did not take too much sebum and had no adverse effect on the skin by using potassium oleate and potassium isostearate as the main components of the cleaning agent described later. A transparent gel detergent composition that gives a moderate moist feeling to the skin after use, is excellent in foaming, cleanability and ease of rinsing that are characteristic of fatty acid soap, and is stable even at low temperatures due to the low Kraft point of oleic acid and isostearic acid The product was successfully developed. Furthermore, the present inventors have found that by adding potassium oleate and potassium isostearate at a specific mass ratio, the gel state can be maintained stably for a long period of time even at high temperatures, and the present invention has been completed.

  That is, this invention exists in the transparent gel-like cleaning composition characterized by including potassium oleate and potassium isostearate, the sum total is 5-50 mass%, and also contains water. Moreover, this invention exists in the said transparent gel-like cleaning composition characterized by being potassium oleate: potassium isostearate = 3: 1 to 1: 3 (mass ratio). Furthermore, this invention is the above-mentioned transparent gel-like cleaning composition characterized by including 1-40 mass% of glycerol further. Further, the present invention resides in any one of the above-described transparent gel detergent compositions, further comprising 0.1 to 10% by mass of a fatty acid alkanolamide type nonionic surfactant.

  By this invention, it is excellent in foaming, detergency, ease of rinsing, imparts a moderate moist feeling to the skin after use, and has excellent stability that can maintain its gel state for a long time even when stored at high or low temperature A detergent composition can be provided.

  The configuration of the present invention will be described in detail below.

  In order to prepare the potassium salt of oleic acid or isostearic acid used in the present invention, a product obtained by neutralizing oleic acid or isostearic acid with potassium in advance may be used, or oleic acid and / or isostearic acid at the time of blending. And potassium hydroxide may be added separately, and neutralization may be performed in the blending system. Moreover, the neutralization equivalent with respect to 1 mol of fatty acids has desirable neutralization of 0.8-1.5 mol. More desirably, 0.9 to 1.2 molar neutralization is desirable, and when this neutralization equivalent is less than 0.8, the gel composition is not obtained, and when neutralization exceeding 1.5 is carried out, the gel form is reduced. There is a risk that it may not be transparent.

It is necessary that 5 to 50% by mass of potassium oleate and potassium isostearate are combined in the final detergent composition of the present invention, and more preferably 10 to 30% by mass. If the blending amount is less than 5% by mass, it cannot take the form of a gel. If it exceeds 50% by mass, solidification occurs at a high temperature during production, resulting in partial crystallization. It is not preferable because it cannot be secured.

  The mass ratio of potassium oleate and potassium isostearate is preferably potassium oleate: potassium isostearate = 3: 1 to 1: 3. By blending at this mass ratio, sensory characteristics such as foaming, detergency and ease of rinsing are obtained, and stability at high temperatures and long-term storage is improved.

  It is preferable that 1-40 mass% is mix | blended with the glycerin used by this invention in the final composition of this invention, More preferably, it is 5-30 mass%. By blending glycerin, the solubility of the fatty acid salt can be increased, and a moist feel can be imparted, but the effect is not obtained with a small blending amount of less than 1% by mass, and 40% by mass. When it exceeds%, the foaming of the final composition is worsened.

Moreover, the compounding quantity is 0.1-10 mass%, More desirably, it is 0.1-3 mass%. If the amount is less than 0.1% by mass, a sufficient effect cannot be obtained, and if it exceeds 10% by mass, the fluidity of the agent during production is impaired.
