Sapindus is a deciduous tree belonging to the family Sapindaceae. It is widely distributed in Southeast Asian countries, Japan, Taiwan and the south of the Huaihe River, and has a very wide range of utilization value.

Sapindus fruit peel contains a large amount of Sapindus sapinsin, which is an excellent plant surfactant. The saponin in the peel contains triterpene saponins, which all have strong surface activity. They are natural non-ionic surfactants, which can make "natural Pollution-free detergent". At the same time, triterpene saponins of Sapindus chinensis have been confirmed to have antibacterial, bactericidal and anti-inflammatory effects on human skin. Sapindus saponins are also excellent pesticide emulsifiers, and have good insecticidal effects on cotton aphids, spider mites and sweet potato Jinhua insects. Pharmacological studies have shown that the Sapindus fruit peel contains saponin components that have anti-dermatophyte and candida effects, inhibit tumor cell proliferation, anti-Helicobacter pylori activity, liver protection and other biological activities. In addition to having a good decontamination effect, Sapindus also contains natural nutrient conditioning substances such as amino acids and vitamins, which have antibacterial, anti-inflammatory, anti-dandruff and itching effects, are less irritating to the skin, are safe and reliable, and are rich in nutritional conditioning ingredients , so that the development of environmental protection products such as biological natural detergents and natural cosmetics has inestimable potential. In addition, Sapindus has beautiful tree shape and well-developed root system, which can absorb harmful gases such as automobile exhaust and sulfur dioxide in the air, and is also of great value in greening, water and soil conservation, and environmental protection. Sapindus saponin has a broad-spectrum elution effect on heavy metals, and the elution rate on lead, manganese, chromium, arsenic, mercury, etc. is above 90%.

Detailed ways

The present invention will be described in detail below in conjunction with specific embodiments, but it should be understood that the protection scope of the present invention is not limited by specific embodiments. The test methods that do not indicate specific conditions in the following examples are usually operated according to conventional conditions, and the sources of unindicated experimental materials are commercially available. Since they do not involve the invention point, the steps are not described in detail.

The invention provides a kind of preparation method of soapberry color handmade soap, comprising the following steps:

S1, preparation of soap base

The reaction principle of making soap base from kitchen waste oil is as follows:

The present invention utilizes saponification method to directly carry out saponification reaction of oil and alkali to prepare soap base, and the principle is represented by the following chemical reaction formula:

The kitchen waste oil is saponified with sodium hydroxide to obtain basic salts of higher fatty acids or mixed fatty acids. Its general chemical formula can be expressed as: RCOONa, where R represents a long carbon chain alkyl group, and glycerin is produced. The resulting soap base has good washing, decontamination, cleaning, moisturizing and other functions.

The steps for preparing soap base are as follows:

S11, waste oil pretreatment

In addition to fatty acid glycerides, kitchen waste oil also contains a lot of insoluble solid impurities such as silt and food residues in the state of suspension or precipitation in the oil, as well as free fatty acids, phospholipids, and pigments in the state of dissolution or emulsification in the oil. , protein and other impurities. In order to meet the requirements of soap making, oil must be pretreated, including two processes of degumming and decolorization. The main raw material that the experiment of the present invention adopts is the kitchen waste oil of university cafeteria.

S111, degumming

Degumming refers to the removal of phospholipids, proteins, and other colloids and mucus in oils and fats. The existence of colloids reduces the use value and stability of oils and fats, resulting in a decline in the quality of soap-based products. In order to achieve the purpose of degumming, the present invention adopts phosphoric acid to treat grease, colloid is coagulated by phosphoric acid, and heavy metals in oil can form phosphate precipitation with phosphoric acid at the same time. The degumming steps are as follows:

Kitchen waste oil is first filtered to remove insoluble impurities such as sediment and cellulose, then heated in a water bath to 40-50°C, sent to a constant temperature magnetic mixer, and mixed with phosphoric acid. The volume ratio of kitchen waste oil to phosphoric acid is 10:1- 2. Stir the obtained oil-acid mixture at 40-50°C for 10 minutes, take it out and let it stand still to coagulate the colloid, and mix the oil containing coagulation with hot water during the stirring process, so that the colloidal impurities such as colloid absorb water and form small colloidal particles Then the upper oil phase liquid and the condensate are separated, and the oil phase liquid is heated in a water bath to remove moisture and air, and finally degummed grease is obtained.

S112, decolorization, deodorization

Kitchen waste oil and degummed grease of S111 will entrain pigment or produce pigment from cooking residue, so decolorization treatment is required. The invention adopts a physical adsorption method to decolorize kitchen waste oil, and uses activated clay and other adsorbents to remove the pigment in the waste oil. The main components of activated clay are SiO ₂ and Al ₂ O ₃ . Specific steps are as follows:

Heat the degummed oil of S111 to 95-105°C, mix it with activated clay, the mass ratio of degummed oil and activated clay is 3:1-2, make it decolorized, and then filter the mixture of adsorbed clay and degummed oil with a filter press Carry out pressure filtration, the pressure filtration parameter that can make the two separate all is suitable for the scheme of the present invention, and the filtrate that collects is decolorized waste oil. During the decolorization process, it can not only dilute the color of kitchen waste oil, but also remove some bad smells.

S12, using the decolorized waste oil to prepare soap base

S121, measure the raw materials for making soap: measure 40g/100ml of sodium hydroxide solution, 95% ethanol solution, and the decolorized waste oil, wherein the volume ratio of the sodium hydroxide solution: ethanol solution: decolorized waste oil is 3:4:3; the addition of ethanol solution is just to make the oil easily soluble in sodium hydroxide solution and make the reaction more complete.

S122, saponification: using a hot saponification method or a cold saponification method, saponifying the raw materials measured in S121 to obtain a saponification solution;

The steps of the hot saponification method are as follows: mix the sodium hydroxide solution, ethanol solution and decolorized waste oil measured in S121, add zeolite, heat, and keep stirring to make the solution boil slightly, observe the liquid level, when a film appears on the surface Heating was stopped to obtain a saponified liquid. At this point, what is obtained is sodium stearate, and there are other substances such as residual alkali, brine, and generated glycerin. Since the density of fatty acid sodium is smaller than that of the solution, floating objects appear, indicating that fatty acid sodium has been generated.

The steps of the cold saponification method are as follows: put the measured decolorized waste oil into a beaker, and then preheat to 45-50°C to obtain solution A; mix the measured sodium hydroxide solution and ethanol solution, and preheat to 45-50°C to obtain solution B; add solution B to solution A, and continue stirring until complete saponification to obtain a saponified solution. The standard for judging complete saponification is: put a few drops of saponification liquid into a test tube, add 2-5 drops of distilled water, heat in a water bath at 100°C and shake continuously. The free oil droplets indicate that the saponification is not complete, and the oil needs to be saponified continuously and tested again until it is completely saponified.

S123, salting out: Pour the saponified solution saponified in S122 into a saturated sodium chloride solution, and the volume of the saturated sodium chloride solution is equal to the sum of the volumes of the raw materials in S121, and stir until soap flocs are formed. Stirring can separate sodium stearate in the salt solution. Since soap is less dense than salt water, it floats on the solution, and the lower layer is to generate glycerin, excess alkali and salt water. After salting out in the solution, filter and collect the floc saponin.

S124, setting the shape: putting the floc soap gel into the mold, and keeping it warm for 24-48 hours under the condition of 30° C. or less, to obtain the shaped soap base. The temperature should not exceed 30°C to prevent the soap base from being heated and melted, which is not easy to form.

S2, preparation of sapindus green handmade soap

Concentrating the sapindella fermented liquid into a colloidal state, melting the soap base described in S124 and merging with the colloidal sapindala fermented liquid, and finalizing the shape to obtain the sapindella enzyme handmade soap. Specific steps are as follows:

S21, heating the Sapindus fermented liquid in a water bath, concentrating it into a colloidal state, and obtaining a colloidal fermented liquid;

S22, take the prepared soap base and heat it to melt. The temperature in this process should not be too high, so as not to burn the soap base. Pour the melted soap base into the colloidal fermentation liquid to obtain a mixture, and keep stirring with a glass rod to control the temperature at 40 ~50°C, after stirring for 10 minutes, pour the mixture into the mold, put the mold in a drying oven at 25-35°C to dry, take out the dried soap base, and place it in a cool place for 2-3 days until it is shaped, and you can get Soapberry enzyme handmade soap, which is dried at 25-35°C to prevent the soap base from being heated and melted, which is not easy to shape.

After the soap base is heated and melted, it is mixed with auxiliary materials to improve the quality of the soap base. The auxiliary material is a sapinsia ferment concentrate, a skin care agent, a flavoring agent or a dyeing agent, and the skin care agent is honey, milk, chocolate powder or animal fat. Honey and milk can moisturize the skin, chocolate powder can activate facial blood vessels and nourish the skin, and animal fat can make laundry soap with a hard soap body; in order to make the handmade soap more beautiful, some natural soap can be added during the preparation process. Dyeing substances, such as carotene, green tea, orange peel extract and other natural dyes. In this way, the environmentally friendly soap base is endowed with colorful color changes, and the soft color enriches the visual effect of the soap base, increasing the quality and promotion value of its products; in order to make it have an elegant aroma, add your favorite natural essential oils according to your personal preferences Or the natural fragrance extracted by oneself, so that the soap base emits an elegant and pleasant smell during use.
