Description

A method for preparing silk fibroin essential oil handmade soap with silk fibroin solution

technical field

The invention belongs to a processing method of silk fibroin, in particular to a method for preparing silk essential oil handmade soap from a silk fibroin solution.

Background technique

my country is a big silk-producing country. In addition to being used in the traditional textile field this year, silk has an adjustable structure due to its good mechanical properties, superior biocompatibility, degradability, and various and relatively simple processing methods. And other advantages, the application development in the field of biomedicine has also made important progress, and because of the application of silk fibroin in biomedical materials, it provides a basis for its application in skin care products.

The silk fiber is hydrolyzed, purified, pulverized, and dried to make a white or light yellow powdery polymer protein, which contains more than a dozen amino acids, has good hygroscopicity and moisture retention, good air permeability, and strong adhesion , can absorb or release water with the change of temperature and humidity, can maintain the balance of hydrophilic and lipophilic, can reduce reflected light, absorb ultraviolet rays, and have special effects on protecting the skin and preventing skin dryness, tanning, and sunburn. Frequent use of cosmetics added with silk fibroin powder can keep human skin moisturized, white and elastic, add natural color and delay aging.

Handmade soap is DIY soap made by yourself. Only oil, NaOH, and water are required. Handmade soap can be used for face washing, makeup remover, and for bathing. The foam of the handmade soap is delicate and rich, which can thoroughly remove the oil stains deep in the pores. Make the skin moisturized, shiny and elastic. The production method is also divided into two types, the hot method and the cold method. The hot method is generally ordinary essential oil handmade soap; and the cold method is called cold creamy handmade soap; The production method cycle is completely different, and it can be said that it is a world of difference. Essential oil soaps are mostly translucent when made quickly, and the colors are very beautiful; cold creamed soaps have a long production cycle and are not fancy.

The handmade soap made from silk fibroin solution using this method has good hygroscopicity and moisturizing properties, and can play a role similar to the natural moisturizing factor (Natural moisturizing factor, NMF) in the stratum corneum of the skin, preventing skin from wrinkling . And it has excellent nutrition, moisturizing, moisturizing and sun protection functions, and can enhance the physiological function and activity of the skin, making the skin soft, smooth, shiny and elastic.

Contents of the invention

The present invention aims at the characteristics of silk fibroin and the vacant field of existing handmade soaps, and develops a kind of handmade soap whose main component is silk fibroin, which has the functions of nourishing, moisturizing and sun protection, and has simple process and convenient handling. method.

In order to achieve the above object, the concrete technical scheme of the present invention is as follows:

The invention discloses a method for preparing essential oil handmade soap from silk fibroin, and the specific preparation steps are as follows:

1) Configure a silk fibroin solution with a concentration of 0.5%-3.5%; 2) Mix the silk fibroin solution and the liquefied soap base according to the ratio of 1mL silk fibroin solution: 1.0g soap base-1mL silk fibroin solution: 3.0g soap base Mix, add pigment, essential oil and olive oil, use vitamin E to adjust the pH to neutral alkaline, stir gently and let it stand for a while; when the ratio is too low, the moisturizing performance, gloss and foaming amount of the product will be reduced; when the ratio When it is too high, the soap base is too dilute and the hardness of the handmade soap is not enough, so add essential oils.

3) Pour the mixed solution into the mold and let it solidify for a period of time, then take out the cured handmade soap.

As a further improvement, the silk fibroin solution of the present invention is a silk fibroin solution prepared by fresh extraction or a silk fibroin solution prepared by dissolving silk fibroin powder. When it is freshly extracted, the ratio of silk fibroin to deionized water is 1:50-1:100, and it is purified by dialysis; when the bath ratio is too small, the concentration of the extracted silk fibroin is too low, causing water, heat and time The waste will affect the use effect, and the economic benefit will decrease; when the bath ratio is too high, the silk fibroin extraction will not be completely waste, and the cost will be increased. If the silk fibroin powder is dissolved, the silk fibroin powder will be dissolved in deionized water.

As a further improvement, the silk fibroin in the present invention is silk fibroin from domestic silkworm or silkworm from wild silkworm.

As a further improvement, the liquid soap base of the present invention is a transparent soap base or milky white soap base, which is formed by microwave heating or external heating.

As a further improvement, the pigment used in the present invention is a natural pigment, and the dropwise amount of essential oil is 0.5-1.5 drops/100mL. Natural pigments are natural pigments that are harmless to the body and come in a variety of colors. You can increase or decrease the amount of drops or add drops in combination as needed to control the color of handmade soap. When the concentration of essential oils is too high, it will be corrosive and increase the cost ; When the concentration of essential oil is too low, the effect of essential oil is not significant, and it will affect the taste of handmade soap.

As a further improvement, the amount of olive oil added dropwise in the present invention is 0.15mL/100mL-0.5mL/100mL; if the concentration is too high, the hardness of the handmade soap will decrease, and if the concentration is too low, the lubricating effect of the handmade soap will be insufficient.

As a further improvement, the essential oils added dropwise in the present invention include various essential oils that meet national standards and are used in cosmetics, such as tea tree essential oil, lavender essential oil, rose essential oil, jasmine essential oil and the like. Under the condition of non-allergic conditions, various essential oils with appropriate concentrations have the effects of soothing emotions, anti-oxidation, antibacterial and antibacterial, and repelling mosquitoes.

As a further improvement, vitamin E is added dropwise in the present invention to adjust the pH, and the adjusted pH is 7-9; when the pH is acidic, the handmade soap has a certain corrosiveness, and the use effect is poor; when the pH is too alkaline, Reduces moisturizing effect.

As a further improvement, the stirring method of the present invention is to stir gently and thoroughly at a uniform speed for 0.25h-2h; when the stirring is not thorough, the solution will not mix uniformly and cause stratification; The quality of the soap, when the time is too short, the handmade soap is not fully cured, and the shape will be changed if it is taken out forcibly. If the time is too long, the time cost will be increased and the production efficiency will be reduced.

Compared with the prior art, the present invention has the following prominent features:

(1) The present invention has the advantages of low energy consumption, high biological safety, low price, simple and convenient operation, and no pollution to the environment during the entire treatment process;

(2) The silk fibroin handmade soap obtained by the invention has the biological characteristics of nourishing, moisturizing and whitening and the physical properties of uniform crystal clear;

(3) The silk fibroin handmade soap obtained by this invention can be used alone to achieve the target characteristics;

(4) The silk fibroin essential oil handmade soap obtained by this invention has additional functions such as sterilization and anti-inflammation, shrinking pores, soothing emotions, and naturally repelling mosquitoes according to the change of the type of essential oil added. Suitable for skin with different characteristics, such as oily and acne skin, dry skin, etc., it can clear the mind, rejuvenate, and resist depression;

(5) The silk fibroin handmade soap obtained by the invention has a greater advantage in the moisturizing effect after use;

(6) The silk fibroin handmade soap obtained by this invention can be made into a variety of styles in different colors and shapes according to user preferences;

(7) The reaction conditions of the whole preparation are mild, the pollution to the environment caused by the use of organic solvents is avoided, and the operation steps are simple.
