Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a highly viscous liquid soap, and more specifically to a stable high-viscosity liquid soap obtained by adding an alkylolamide to an aqueous solution in which sodium and potassium salts of fatty acid-based soap coexist. Concerning viscous liquid soap group paraboloid.

In recent years, hygiene management has improved and public facilities, public facilities, and even homes have washrooms and hand-washing facilities. However, the stone ken of the alliance is left there, dirty and black, but the reality is that it is filthy and unused. The present invention
In particular, as a sanitary product, it has been adjusted so that a certain amount of liquid soap can be dispensed in a sanitary and sanitary manner by pushing and pulling the lever of a container with a certain capacity (hereinafter referred to as a dispenser). It is something.

If it is used for such a purpose, for example, the conventional one is an aqueous solution of potash soap, which has a low viscosity like water and can easily spill from the palm of the hand (through the gaps between the fingers). When dispensing from the ivy p1 dispenser, it splatters and stains clothes, etc. It is also necessary to increase the viscosity from the product value page.

Common methods for thickening include using inorganic salts in water-soluble polymeric substances such as starch, natural gums, sodium alginate, methyl cellulose, and pvA. However, when a water-soluble polymer is used, a film forms at the discharge port of the dispenser, making it impossible to discharge the solid powder smoothly, or giving a sticky feeling when using it. Also, inorganic salts have no thickening effect in the case of soap (they are inappropriate).

The present inventor added an alkylolamide, which has been conventionally known as a viscous active agent, and by limiting the blending ratio of the sodium salt and potassium salt of the fatty acid group.
The inventors have discovered that it is possible to obtain a desired high-viscosity liquid soap that does not suffer from the above-mentioned film-forming problems, stickiness, etc. during use, and have completed the present invention.

The fatty acid group used in the present invention is a fatty acid obtained from natural fats and oils, such as coconut oil, olive oil, tall oil, beef tallow, etc., but it is preferable that the fatty acid composition contains at least 30116 oleic acids. Preferably, the sodium and potassium salts are used.

1.0 to 40% by weight of the above fatty acid group (combined sodium salt and potassium salt), preferably 5 to 2%
5 weight - can be blended, the ratio of sodium salt to potassium salt is 3:1 to 1:10, preferably 1:1 to 1:5. In this specification, the following - and parts are not specified.
r based on weight. Fatty acid monoethanolamide and fatty acid jetanolamide can be used as the alkylolamide, but coconut oil fatty acid and jetanolamine can be used in a ratio of 1:
Coconut oil fatty acid jetanolamide condensed with 1 is preferably blended in an amount of 1 to 10% by weight - preferably 2 to 6% by weight.
A stable high viscosity soap solution can be provided by mixing the ingredients.

Preferred viscosity conditions for thickened soap solutions for use in dispensers are 1000 to 5 at 20°C.
0000apm is the best! 5000 ops
It is s to 20,000 cruelties.

The soap liquid manufactured according to the present invention fully satisfies this requirement, and solves the problems of scattering and spilling from hands when discharged from the S1P dispenser, and also solves the problem of solidification at the discharge port. . Since it is provided as a hand-washing soap solution, oils and fats such as lanolin and squalene, moisturizing agents such as PCA and peptides, disinfectants such as Condidi 1 engaging agent, isoptetravirmethylphenolhibiten, and ethylene glycol are added as necessary to replenish the oil and fat content. Pearlizing agents such as stearate and fish scale foil, fragrances, etc. can also be blended as appropriate. The highly viscous liquid soap obtained in this way is widely used as an environmental hygiene product for hand washing and as a toiletry product.The general semi-manufacturing method first involves extracting ingredients that are difficult to dissolve in water (for example, If agent i) is present, add it to the light and heat it to 70°C if necessary. Next, add the fatty acid groups (sodium salt) and (potassium salt), stir evenly, and confirm that the mixture is well-oiled. Add the coconut oil fatty acid jetanolamide and cool to 50°C. (Optional fragrance, Add conditioning agent to obtain desired liquid soap.

The invention will now be illustrated by the following examples.

Each test in the following examples is as follows: 9 lines x 9.

0) Viscosity Measure the viscosity at 20°C using a Type 2 B viscometer.

■ Film forming test: Pour 30117 soap solution into a 501 beaker, leave it at 30°C for 24 hours, and check the film forming property of the liquid surface.

6) Usage test The two-soap sapon solution is actually used, and the slimy, sticky feeling is measured by a sensory test.

Example I A soap base material, an alkylolamide, and others (pigments, fragrances, and bactericides) having the composition shown in III are heated at a temperature of 100° C. or less, and dissolved with stirring. When the mixture was completely mixed, it was cooled and filled to obtain a product.

Table I As is clear from these results, in the formulation of single sodium salts and potassium salts of fatty acids, there are problems such as gelation or inability to obtain the desired viscosity. By combining the salts in a 1:1 ratio, the desired viscosity can be obtained, and a product can be obtained without problems of film formation, sliminess, or stickiness.

Example (2) Similar to Example I, tests were carried out with different mixing ratios of various raw materials, and the results are shown in Table 2.

As described above, the high viscosity liquid surface stylus of the present invention is made by combining alkali salts of soaps in a specific proportion and adding alkylolamide to prevent stickiness as in the past, or to form a film using a thickener. These problems have been solved, and a high-viscosity, high-quality soap solution that meets the intended use can be obtained, which is extremely excellent in terms of environmental hygiene.
