JPS5835560B2 - Comfrey-containing solid cleaning composition - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solid detergent containing comfrey, and more specifically, it is characterized in that comfrey is blended into a detergent base containing N-long chain acyl glutamate as an essential component. The present invention relates to a comfrey-containing solid detergent composition that stably maintains its green color.

Comfrey in the present invention is a perennial plant that reaches 1 m in height and is native to Europe.
It is said to be effective in treating internal bleeding, ulcers, trauma, and burns, and in ancient Europe, the leaves have been used as folk medicine, or the roots, stems, and leaf powders and decoctions have been used internally or externally.

Even in Japan, many people recognize its value as a medicinal herb.

Comfrey contains chlorophyll, vitamins, carbohydrates, and minerals, which are typical of plants, but it also contains allantoin.

Allantoin, one of the ingredients in comfrey,
It is already widely known that contact with the wound surface promotes granulation generation on the iron surface and has a remarkable effect of removing necrotic tissue.

Therefore, it is common practice to formulate these substances or derivatives into therapeutic agents.

On the other hand, rolophilia has the effect of stimulating diseased tissue and promoting tissue recovery, and is known to be prescribed in ointments for the purpose of treating trauma, and added to toothpaste and chewing gum.

Therefore, it is believed that the traditional therapeutic effects of comfrey on the various diseases mentioned above in dogs are due to the effects of allantoin and chlorophyll contained therein.

The present inventor paid attention to such useful properties of comfrey and conducted various studies on skin cleansing agents containing comfrey.

However, it has been discovered that a serious flaw occurs when manufacturing solid cleaning products containing comfrey.

In other words, the color of fatty acid soaps containing comfrey and solid detergents based on Symptobar is unstable;
During manufacture, storage, and use, the color changes from green to blackish brown.

Comfrey is a green plant, so if a composition containing this substance is not able to maintain its green color, it will seriously damage the image of the product, despite its traditional effects as described above. There is.

However, it is also true that the green color of plants tends to disappear when exposed to sunlight, as evidenced by the fact that collected leaves wither and turn brown.

The green color of comfrey is due to the presence of chlorophyll, but chlorophyll and chlorophyllin have strong pigment hiding power, and fatty acid soaps, waxes, fats and oils,
It is already widely known that it is useful as a green coloring agent for foods and the like.

However, when used as such a coloring agent,
Since natural products change color, chlorophyll M
So-called copper chlorophyllin, in which g is replaced with Cu, is used.

However, it is known that the presence of even a trace amount of free copper ions in detergent bases such as fatty acid soaps is undesirable, such as causing discoloration.

In order to find a product that does not cause discoloration when blending natural comfrey into a detergent base, the inventor sought a system that does not cause discoloration when blending various surfactants with comfrey. .

As a result, it was found that only the combination with N-long chain acyl glutamate did not cause green discoloration, and the present invention was completed.

That is, the present invention is a solid skin cleansing composition containing N-long chain acyl glutamate and comfrey powder or green juice as essential ingredients.

The product of the present invention is prepared by mixing N-long chain acyl glutamate, comfrey, and, if necessary, other auxiliary materials such as higher alcohol, fatty acid alkylolamide, etc., and solidifying the mixture by a conventional method.

The comfrey used in the present invention may be a dry powder containing only the leaves or a dry powder containing stems and the like together with the leaves.

Alternatively, so-called green juice obtained by crushing leaves, stems, etc. using a mixer or the like may be used.

Further, the N-long chain acylglutamate used in the present invention has an acyl group having 10 to 20 carbon atoms, and may be a monosodium salt, a monopotassium salt, or a mixture of these salts.

As explained in the Examples below, when comfrey is applied to a skin cleansing agent, the maintenance of the green color appears to be due to the unique effects of monosodium and monopotassium N-long chain acylglutamates. However, the reason for this effect is unknown.

The effect of N-long chain acylglutamate suggests that it can be applied to detergent compositions containing other substances containing chlorophyll as well as comfrey.

The present invention will be explained in detail below with reference to Examples.

Example I N-hardened beef tallow fatty acid acylglutamate monopotassium
75 parts comfrey dry powder 1) 15 parts water
10 parts 1) After drying the washed leaves and stems until the moisture content is about 2 ml, grind them with a ball mill to 0.1 mm.
What passed through the sieve.

The above-mentioned blended product was mixed using a mixer, extruded using a mechanical soap manufacturing device, and molded to obtain a molded product.

This molded product was left in a constant temperature phase maintained at 40° C. and indoors near a window for 7 days to perform a color fading test.

As a result, the green color before the test (JISZ-8721-
The color (close to 2.50Y'/4 in the 1964 standard color chart) was sufficiently maintained.

Example 2 Mononarylium N-coconut oil fatty acid acylglutamate
75 parts comfrey dry powder (
Same as Example 1)) 20 parts Water 8 parts The above blended product was molded according to Example 1, and then a discoloration test was conducted.

This product maintained its green color before the test.

Example 32) Monosodium N-mixed fatty acid acylglutamate
49 parts Monosodium N-lauroylglutamate 21 parts Comfrey dry powder (same as Example 1) 15 parts Polyethylene glycol 400 5 parts Water
□0 part 2) Beef fatty acid 80
The above-mentioned mixed fatty acid mixture containing 20 parts of coconut oil fatty acid was molded according to Example 1 and tested in the same manner as in Example 1.

This product maintained its pre-test color.

Example 4 85 parts of monosodium N-lauroyl glutamate Comfrey green juice 3) 15 parts 3) Water obtained by adding 150 parts of water to 159 pieces of comfrey leaves washed with water and stirring and crushing them in a household mixer. The blended product was molded according to Example 1 and tested in the same manner as in Example 1.

This product maintained its pre-test color.

Example 5 After thoroughly mixing each of the above A, B, and C with a mixer, the mixture was poured into a stainless steel cylindrical mold with an inner diameter of 50 mm, maintained at a gauge pressure of 80 kg/i for 2 minutes using a hydraulic machine, and made into a tablet. I got a body wash.

This pressure molded product was tested in the same manner as in Example 1.

These A and B. All samples C maintained their pre-test colors.

Comparative Example 1 Toilet soap base 4) 72 parts comfrey dry powder (same as Example 1) 20 parts water 8 parts 4) Obtained by saponifying, salting out, and drying fats and oils consisting of SO% beef tallow and 20 g of coconut oil. It has a moisture content of approximately 14%.

The above formulation was molded in the same manner as in Example 1.

In this molded product, the green color of the dry comfrey powder disappeared, and the molded product took on a color close to black.

When this color was compared with the standard color chart of JISZ-8721-1964, it was found to be close to the color chart of 5Y2/1.

Comparative Example 2 Sodium lauryl sulfate 72 parts Comfrey dry powder (same as Example 1) 20 parts Water 8 parts Comparative Example 3 Sodium lauroyl sarcosinate 70 parts Comfrey dry powder (same as Example 1) 20 parts Water 10 parts Comparative example 2
and 3 were molded and tested in the same manner as in Example 1.

As a result, no discoloration was observed in the molded products of Comparative Examples 2 and 3, as in each Example.

When this product was subjected to a hand washing test with warm water, it turned black within 1 hour after contact with water, and the color was comparable to that of Comparative Example 1.

However, the product of the present invention maintained its original color without discoloration even after the hand washing test.

As explained above, only the combination of N-acylglutamate and comfrey of the present invention was able to maintain the green color during storage and when using hot water.

Furthermore, a molded product containing comfrey and N-acylglutamate according to the present invention was investigated for its feel when used.

The molded products used in the investigation were the molded products shown in Example 3 and the molded products from which the comfrey dry powder was removed.

The research method used was to have 10 male and 10 male adults use the molded product while bathing, and then have them compare and evaluate the superiority and inferiority of various properties.

The results are shown in Table-1. The numbers in the table are the number of people who judged the performance to be excellent.

Table 1 Amount of foam equivalent to DEDE 1 2 17 Fineness of foam 16 3 1 Smoothness of soap during use 1541 Smoothness of skin after washing 13 2 5 Gloss of soap surface after use 116 3 D = Product of the present invention E : Products that do not contain comfrey As is clear from Table 1, the products of the present invention have finer foam and a smoother soap when used, compared to products that do not contain comfrey.

These properties are thought to be due to the effects of the gum contained in comfrey.

On the other hand, the gloss on the surface of the soap after use was said to be inferior to that of soaps that did not contain comfrey, but this is also thought to be due to the gum quality dissolved.

According to an interview survey of 20 people who participated in the survey, an overwhelming majority of respondents said that the lack of surface gloss after using the product of the present invention was not to the extent that it would pose a practical problem.
