Description

Technical Field

[0001] The invention relates to the field of daily cosmetics and cleaning products, and in particular to a deep-cleaning and odor-removing handmade soap and a preparation method thereof. Background Art

[0002] As a natural cleaning product, handmade soap is not only required to have the function of skin cleaning, but also some new functions such as beauty, sterilization and deodorization with the improvement of living standards. The generation of body odor is related to many factors, among which bacteria is an important factor. Body odor is mainly produced by bacteria on the surface of the skin decomposing organic matter in sweat. The apocrine glands of the human body are mainly distributed in the armpits, groin, areola and other parts, and the sweat secreted contains organic matter such as protein and fatty acids. When these organic matter are used by Staphylococcus and Corynebacterium on the surface of the skin for metabolic activities, some volatile compounds such as isovaleric acid and butyric acid will be produced, which are the main components of body odor. In addition, the skin may absorb volatile trimethylamine, piperidine and other odors of fish and seafood in life, smoke, hot pot smell, sulfur-containing compounds and oxygen-containing compounds that are exposed during work, which are difficult to remove by simple water washing, affecting our living comfort and may also pose a potential threat to our health.

[0003] At present, soap products mainly remove odors by adding fragrance ingredients to cover up the odor with a strong fragrance. However, if the amount of fragrance used is small, it is difficult to completely cover up the odor or the effect is difficult to sustain. If the amount of fragrance used is large, long-term use may cause respiratory irritation, reduce respiratory immunity, cause skin allergies, cause headaches, dizziness, etc., causing certain harm to human health, and does not improve the fundamental cause of the odor.

[0004] Activated carbon is widely used in many fields due to its unique adsorption properties. In soap products, activated carbon can help remove impurities, odors, etc. It can not only deeply cleanse, but also improve skin problems to a certain extent. However, how to improve its stability in soap products is an issue worthy of in-depth discussion. Although activated carbon itself does not breed bacteria, soaps are placed in humid and warm environments such as bathrooms and are soaked in water for a long time. Activated carbon may absorb too much water, and its loose and porous structure also provides a suitable growth environment for bacteria. Therefore, soap products with activated carbon still have defects. Using the advantages of activated carbon to develop soap products with deep cleaning and odor removal has broad market application prospects. Summary of the invention

[0005] In order to improve the cleaning, sterilization and deodorizing capabilities of handmade soap, and make the handmade soap also have extremely low irritation.

[0039] S3022. Collect the filtrate by filtering through gauze;

[0040] S3023. Concentrate the filtrate under reduced pressure to remove ethanol to obtain tea tree essential oil.

[0041] Beneficial effects:

[0042] In the first aspect, the ammonia-modified silver-carrying activated carbon of the present invention is modified by ammonia reduction, so that the elemental silver is not only distributed on the outer surface of the activated carbon, but also fully distributed in the pores of the activated carbon, so that the silver and the activated carbon are firmly combined, which can improve the ability of the silver-carrying activated carbon to resist silver loss, thereby achieving a stronger antibacterial or bactericidal effect, and improving the applicability of soaps in environments that are prone to breeding bacteria, such as humid and warm bathrooms. On the other hand, the specific surface area of ​​the activated carbon is increased, and the alkaline groups on the surface are increased, so that the silver-carrying activated carbon has a stronger adsorption capacity for non-polar substances and volatile gases. When it is added to soap products, it can take away non-polar oils and odor components that are insoluble in water on the skin surface when cleaning the skin, and play a role in deep cleaning and deodorization.

[0043] On the second aspect, from the above, ammonia modified silver-carrying activated carbon with strong cleaning ability is used for soaps, although it can improve the cleaning ability, the skin problems caused by strong cleaning ability make ammonia modified silver-carrying activated carbon difficult to be used for soaps. The coconut oil in the present invention provides the basic hardness and foaming property of handmade soap, and sweet almond oil, red palm oil and horse oil all have the characteristics of mild and non-irritating, suitable for the characteristics of various skin qualities including sensitive skin, and are also suitable for the skin after deep cleaning, preventing the problems of dry skin and peeling caused by excessive cleaning. In addition, the red palm oil is rich in nutrients such as vitamin E and carotene, which plays an important role in the normal metabolism and repair of the skin. Horse oil also contains natural antibacterial ingredients, which have a certain inhibitory effect on some bacteria, fungi and other microorganisms on the skin. From the above, the oil phase of the present invention is selected, and the skin problems caused by deep cleaning can be prevented and repaired, so that the ammonia modified silver-carrying activated carbon with strong cleaning ability of the present invention can be applied to handmade soap for cleaning skin, so that light skin irritation and strong cleaning ability can be integrated.

[0044] On the third aspect, the ammonia-modified silver-loaded activated carbon of the present invention can effectively adsorb dirt formed by excess oil, naturally shed keratin, dust, etc. on the skin surface, and reduce organic matter on the body surface that is easily used by bacteria to produce odor. In order to further exert the adsorption effect of activated carbon on such components, the present invention adds papain to degrade protein components in the skin such as keratin, promote the adsorption effect of activated carbon on the above components, and the two synergistically enhance the skin's cleaning ability and deodorizing ability.

[0045] In the fourth aspect, the main microorganisms on the surface of human skin include Propionibacterium, Staphylococcus, Corynebacterium, Malassezia, etc. The protamine peptide of the present invention can release more positively charged groups by hydrolyzing protamine, destroying the cell wall structure of Gram-positive bacteria such as Propionibacterium, Staphylococcus, Corynebacterium, and interfering with their cell metabolism to achieve an inhibitory effect. The silver element and tea tree essential oil of the ammonia-modified silver-loaded activated carbon of the present invention have a good inhibitory effect on fungi such as Malassezia. Under the synergistic effect of the three, a more comprehensive and deep bactericidal effect is achieved, fundamentally reducing the body odor caused by bacterial decomposition of organic matter.

[0046] In the fifth aspect, the zinc ricinoleate in the present invention has a good adsorption effect on hydrogen sulfide and mercaptan odors produced by chemical plants and farms, and small molecular organic acids such as isovaleric acid contained in human sweat. However, the adsorption effect on organic acids with large molecular structures and large steric hindrance is relatively poor, while the ammonia-modified silver-loaded activated carbon of the present invention also has a good adsorption effect on large molecular organic acids and non-polar odor substances. The two are synergistic and complementary, and can fully and deeply adsorb and remove odor substances attached to the skin in a relatively short cleaning time, and have an excellent odor removal effect.

[0047] In the sixth aspect, the ammonia-modified silver-loaded activated carbon of the present invention can effectively adsorb dirt formed by excess oil on the skin surface, naturally shed keratin, dust, etc., reduce the organic matter on the body surface that is easily used by bacteria to produce odor, and also has a good adsorption effect on large molecular organic acids and non-polar odor substances. Protamine peptide, silver element of ammonia-modified silver-loaded activated carbon, and tea tree essential oil fundamentally reduce body odor caused by bacterial decomposition of organic matter. Zinc ricinoleate has an effective removal effect on hydrogen sulfide and thiol odors produced by chemical plants and farms, and small molecular organic acids such as isovaleric acid contained in human sweat. The above combination can have the effect of avoiding the generation of odors and effectively removing the generation of odors in various dimensions of odor generation, so that the handmade soap of the present invention can fundamentally solve the odor problem.

[0080] (3) Cleaning ability experiment: Chicken breast meat was dried and ground into powder as protein dirt, which was mixed with lard in a ratio of 1:2 and 20% polydimethylsiloxane was added to improve the spreadability as artificial dirt. Thirty volunteers with no skin diseases, uniform color and no trauma on the inner forearms were selected. Two symmetrical hairless areas on the inner forearms of the left and right arms were randomly numbered A and B, and a dermatoscope was used to take pictures of each test area. After washing and drying naturally, the samples were washed at 3 mg / cm 2 The amount of dirt was applied to the test area of ​​the volunteer's arm, and the application was evenly dried naturally. A dermatoscope was used to take pictures of each test area. The test product was applied to two different areas, A and B. Test area A: The handmade soap prepared in Example 1 was dissolved in clean water at a ratio of 1:10 to form a soap solution, with an amount of 2 mg / cm 2 Test area B: The handmade soap prepared in Example 4 was dissolved in clean water at a ratio of 1:10 to form a soap solution with a dosage of 2 mg / cm 2.
