Description

Fish scale exfoliating cleansing soap and preparation method thereof

The invention relates to the composition of the cleansing soap, in particular to a fish scale exfoliating cleansing soap and a preparation method thereof.

According to the fish scales, fish scales are usually regarded as waste by fishermen. Most of the treatment methods for fish scales are directly discarded or crushed to make fertilizers, which not only causes waste of resources but also burdens the environment. The fish scales account for about 3 to 5% of the total weight of the fish. Recently, the study found that the main components of the scales contain 45% collagen and 55% Hydroxy-Apatite (HAp). Among them, collagen is widely used in the field of medical beauty, while hydroxyapatite is the same as human bones, has high biocompatibility and no cytotoxicity, and is often used in orthopedics and dental materials. Therefore, the research and development of fish scales can not only transform waste into products of high economic value, but also effectively reduce the pollution caused by abandoned fish scales.

Furthermore, the stratum corneum in the human skin can prevent foreign substances from entering the body and prevent the water from dispersing in the body, but as the age increases, the stratum corneum gradually accumulates, making the active ingredients in the water-soluble cosmetics more difficult to enter the skin. The market is advertised as a cleansing soap with exfoliating function. Most of them add plastic particles to the soap body, and the plastic particles can be rubbed against the skin during use to achieve exfoliation, but the soap body The practice of adding plastic particles has been severely affected by many countries because the plastic particles cannot be decomposed and have a serious impact on the environment.

In contrast, the hydroxyapatite in the fish scale is also a natural, mild, and physical exfoliating agent. Therefore, the composition of the cleansing soap by the hydroxyapatite in the fish scale can not only achieve the effectiveness of the discarded fish scale. It can also be used to increase the effectiveness of skin absorption and increase its added value.

The main object of the present invention is to provide a fish scale exfoliating cleansing soap and a method for preparing the same, which can achieve effective reuse of discarded fish scales, and can also increase the effectiveness of skin absorption to enhance the added value.

For the purpose of the foregoing, the present invention provides a fish scale exfoliating cleansing soap, which comprises oils and fats and sodium hydroxide as a main component, and comprises fish scale powder having a particle diameter of 28 to 60 mesh, and the weight ratio of the fish scale powder is fat. 15~20%.

Furthermore, the present invention further provides a fish scale exfoliating cleansing soap preparation method comprising the following steps:

a. The fish scale is ground into a powder having a particle size of 28 to 60 mesh, and a fish scale powder is obtained;

b. In the soap making process, the oil is mixed with sodium hydroxide and added to the fish scale powder to obtain half of the finished product, wherein the weight ratio of the fish scale powder is 15-20% of the fat;

c. After stirring the semi-finished product to a thick state, it is poured into a container and allowed to stand until it is hardened.

Preferably, the oil or fat may be composed of olive oil, soybean oil, canola oil, cocoa butter or coconut oil.

Further, the semi-finished product is demolded after the container is allowed to stand until it is hardened, and the released soap is placed in a cool and dry place, and the pH is lowered to 10 or less.

The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments of the invention.

The invention provides a fish scale exfoliating cleansing soap preparation method, which can be mainly divided into a preparation process of fish scale powder and a preparation process of soap.

As shown in Figure 1, the preparation process of the fish scale powder includes the following steps:

1-1. Pre-treatment: Take the fish scales of the milkfish ( Chanos chanos; Milkfish ) as raw materials, and heat the fish scales in boiling water at 100 °C for about one minute to remove the microorganisms and bacteria on the surface of the scales to avoid protein spoilage. The taste is further completed, and then the fish scales are washed with water, and then the fish scales are dried at a temperature of 60 ° C for one day.

1-2. Milling and sieving: The dried fish scales are ground and sieved with a mesh of 28-60 mesh to obtain fish scale powder with a particle size of 28-60 mesh.

As shown in Figure 2, the soap preparation process includes the following steps:

2-1. 82 g of sodium hydroxide (NaOH) was added to dissolve in 125 ml of water to obtain a sodium hydroxide solution.

2-2. The 455 g of coconut oil was heated in a stainless steel pan over a small fire. When the temperature was close to the temperature of the formulation (50 ° C), the stainless steel pan was fired. Among them, there are many kinds of oils that can be used in soap making. In theory, various edible oils can be used, such as olive oil, soybean oil, canola oil, cocoa butter, etc., but the hardness of the soap made by the higher melting point is suitable. Of course, different oils or combinations of oils and fats may be used according to individual needs. In the present embodiment, coconut oil is taken as an example.

2-3. Slowly pour the sodium hydroxide solution into a non-fired stainless steel pot and gently agitate. The temperature of the sodium hydroxide solution should reach the temperature of the formula (50 ° C), and the method of separating the temperature by using the water is adopted. Sodium hydroxide can saponify fatty acids in fats and oils to make soap. The amount of sodium hydroxide varies depending on the oil.

2-4. After the coconut oil is dissolved with sodium hydroxide, the fish scale powder having a particle size of 28 to 60 mesh is added, wherein the weight ratio of the fish scale powder is 15 to 20% of the coconut oil.

2-5. Stirring is continued until a thick mixture is obtained.

2-6. Pour the thick mixture into a container or mold and allow the container to stand for 24 to 48 hours, at which point the container can be wrapped with a towel or blanket to maintain the desired temperature for saponification.

2-7. After the soap is hardened and solidified, the mold is released, and the soap after the mold release is placed in a cool and dry place. When the pH value is lowered to 10 or less (cooked), the present invention can be obtained by using the oil and sodium hydroxide as main components. The fish scale powder having a particle size of 28 to 60 mesh is included, and the weight ratio of the fish scale powder is 15 to 20% of the fish scale exfoliating cleansing soap.

Next, the following experimental examples are combined with the test results to further illustrate the achievable effects of the present invention.

First, the effect of adding fish scale powder with different mesh numbers on the pH value of soap

First, the main components of the fish scales of the milkfish are protein and ash. Table 1 shows the general composition of the fish scales of the milkfish of the present invention. The results show that the fish scales of the milkfish contain 51.75% of the crude protein followed by 44.74% of the ash, and the crude fat content is about 0.66%. Table 1. Analysis of the general composition of fish scales

Then add 15% and 20% different mesh number of fish scale powder to affect the pH value of the soap, wherein 15% and 20% refer to the amount of fish scale powder added in the soap preparation process (ie the weight ratio of fish scale powder to fat) ). As shown in Table 2, the pH value will decrease with time in the process of ripening with 15% fish scale powder. In the third chart, the experimental group with added fish scale powder can be seen, and the pH value is stable and fast. It is speculated that the possible cause is that the collagen in the fish scale powder has a protein buffering effect, and the group in which the fish scale powder is added can reach 10 or less in about 7 weeks. Table 2, the effect of adding 15% different mesh number of fish scale powder on the pH value of soap

As shown in Table 3, it is shown that the addition of 20% different mesh number of fish scale powder has an effect on the pH value of the soap. The results show that the pH drop rate is 15 when the addition amount is increased to 20% as shown in Fig. 4. % is stable and fast, and the group of fish scale powder added can reach 10 or less in about 5 weeks. Table 3, the effect of adding 20% different mesh number of fish scale powder on the pH value of soap

Second, the number of colonies test

The colony number test was carried out by allowing the subjects to wash their hands with soap, washing them with a sterile cotton swab before washing, and collecting the hand microbes once, and applying them to TSA agar (medium) for cultivation. After one day of culture, colony counts were performed.

Firstly, the number of microbial colonies of the fish scale soap added with different mesh numbers was tested. The results are shown in Table 4. Together with Figure 5, the changes of microorganisms in the hands before and after washing hands can be seen, and the experimental group and the control group are observed. After washing the hands, the number of colonies decreased, but the 15% 28mesh soap microbes decreased the most. It is estimated that the 15% 28mesh soap added the size of the fish scale powder is moderate, which can increase the soap detergency. Table 4, the influence of the number of microbial colonies on the scale of the fish scale soap of 15% different mesh numbers

Then, the number of colonies of the fish scale soap made by different 15% and 20% fish scale powders was measured for the number of 28mesh. The results are shown in Table 5, and the figure 6 shows the microbes of the hands before and after washing hands. Changes, and observed that 20% 28mesh soap microbes decreased the most, meaning that the addition of fish scale powder increased, the detergency also increased. Table 5, the effect of the number of microbial colonies on the palm kernel of different proportions of 28mesh

It can be seen from the above test that the number of meshes is smaller and the particles are larger. In the case of 28 mesh, the particles are the largest of the three. The present invention utilizes a fish scale powder of 28 to 60 mesh added to the soap making process, and the frictional force is enhanced by the particles, so that the 28 mesh is most moderate.

Third, smoothness detection

The method of smoothness detection is to perform a test on the subject before the start of the experiment. The experiment was conducted for five days and the subjects were given soap once a day. The second test was performed after the soap was used on the fifth day.

The smoothness test was carried out with 15% different mesh number of fish scale soap on the skin of the opponent. The results are shown in Table 6 and Figure 7. The soap with 28mesh and 60mesh scales has a smooth skin after one week of experiment. Rise, although the smoothness is slightly higher than 60 mesh, but there is no statistically significant difference between the 28m and the 28mesh before washing, that is, both can increase the smoothness. It can be observed from the data that both 28 mesh and 60 mesh can increase the smoothness because the friction between the fish scale particles and the hand skin is moderate, and the particle size of 28 mesh and 60 mesh is moderate. Table 6. Effect of 15% different mesh number of fish scale soap on skin smoothness  <TABLE border="1" borderColor="#000000" width="85%"><TBODY><tr><td> Smoothness</td><td> 0% </td><td> 15% 28 Mesh </td><td> 15% 60 mesh </td><td> 15% 100 mesh </td></tr><tr><td> before</td><td> 4.80 </td> <td> 4.60 </td><td> 4.00 </td><td> 4.20 </td></tr><tr><td> After </td><td> 4.80 </td><td> 6.20 </td><td> 5.80 </td><td> 4.20 </td></tr></TBODY></TABLE>

In summary, the present invention is a fish scale exfoliating cleansing soap prepared by adding a fish scale powder of 28 to 60 mesh, and the finished product is as shown in Fig. 8, and can be helpful in the process of soap formation. The pH value of the soap drops more rapidly, and the more the amount of addition, the faster and the more stable the drop. In the hand microbial test, the soap added with the fish scale powder helps to increase the detergency of the soap. Add 20% 28 mesh fish scale soap is the best, and in the hand skin smoothness test, adding the milkfish scale powder helps the skin smoothness rise, it is obvious that it has excellent exfoliating function, which adds 28mesh The soap made from the fish scale powder is more moderate. On the whole, the soap added with 28mesh fish scale powder has better ability to exfoliate, and at the same time makes the microorganisms less likely to adhere to the skin, so it has strong detergency and can simultaneously increase the detergency (microbial removal ability). And the effect of skin smoothness, which in turn can greatly increase its added value.

It should be noted that the above description of the embodiments is merely illustrative of the invention and is not intended to limit the invention, and that variations of the numerical values or substitution of equivalent elements are still within the scope of the invention.

In summary, when it is known to those skilled in the art that the present invention can achieve the foregoing objectives, it has been in compliance with the provisions of the Patent Law, and therefore an application is made according to law.
