Problems solved by technology

But this amino acid cleansing paper has the following problems: one is to use starch or modified starch as a film-forming agent, which has unsatisfactory physical strength and insufficient apparent flexibility. Therefore, the cleansing paper is easy to crack, fall apart, and easily Adhesion, which affects the use of the product; second, the retention rate of active ingredients in the cleansing paper is generally low, it is difficult to meet the requirements of consumers, which affects the promotion and use of the product; third, the cleansing paper does not have the effect of moisturizing and moisturizing the skin
[0010] At present, there are relatively few studies on soluble cleansing paper, and further experiments on how to improve the performance of cleansing paper need to be conducted by scholars. Therefore, it is necessary to provide a kind of Soluble cleansing paper with superior performance and good effect, moisturizing and moisturizing effect

Embodiment 1

[0036] Embodiment 1, the preparation of soluble anionic starch

[0037] Described soluble anionic starch is made by following steps:

[0038] S1) Enzymolysis: Take pea starch, add a certain amount of citric acid-disodium hydrogen phosphate buffer solution, stir and gelatinize in a boiling water bath, take it out, constant volume, prepare a gelatinized starch solution of 20mg / ml, and keep the temperature at 45°C Shake in a water bath for 10 minutes, add α-amylase, enzymatically hydrolyze for 80 minutes, stop the reaction to obtain starch hydrolyzate, and set aside;

[0039] S2) Cross-linking: Add soybean oil, sodium hydroxide solution, Span-80 and epichlorohydrin to the above starch enzymatic hydrolysis solution, stir and mix, wherein, soybean oil, sodium hydroxide solution, Span-80 and epoxy The weight ratio of chloropropane is 1:1:0.2:0.5;

[0040] S3) Anionization: add ethanol solution, monochloroacetic acid, sodium hydroxide solution and the starch enzymatic solution tre...

Embodiment 2

[0042] Embodiment 2, the preparation of cationic nano-microcrystalline cellulose

[0043] The cationic nano-microcrystalline cellulose is prepared by the following steps:

[0044] Take microcrystalline cellulose, crush it, pass through a 20-mesh sieve, add 150ml of 45wt% hydrochloric acid at 45°C, stir, react for 40min, add 9 times the volume of deionized water to dilute to terminate the reaction, and use deionized water to dilute the obtained product repeatedly. Centrifuge and wash to pH 5.0; put the obtained product into a dialysis bag, use flowing deionized water to dialyze the paper to a constant pH value, and treat the dialyzed suspension with an ultrasonic oscillator for 10 minutes to obtain nanocrystalline cellulose suspension liquid, in order to avoid product aggregation due to heat, the treatment is carried out in a hot water bath;

[0045] Add the above-mentioned nano-microcrystalline cellulose suspension to phosphate buffer solution to obtain a nano-microcrystall...

Abstract

The invention belongs to the field of cosmetics and particularly relates to soluble cleansing paper capable of moistening and moisturizing and a preparation method thereof. The soluble cleansing paper contains the following components by mass fractions: 80-95% of a carrier component and 5-20% of an active ingredient, wherein the carrier component is prepared from the following raw materials by mass fraction: 75-80% of soluble anionic starch, 17-25% of amylase and 1-5% of kation cellulose nanocrystal; and the active ingredient is prepared from the following raw materials by mass fraction: 0.5-3% of surfactin, 3-6% of watermelon skin peptide, 0.5-3.5% of hyaluronic acid, 1-5% of a glossy privet fruit extract and 85-90% of water. The cleansing paper is small in volume and convenient to carry, the mean thickness is 0.2mm, excessive oil and dust dirt on the skin surface and in pores can be safely and effectively cleaned, the soluble cleansing paper is skin-friendly, and free of any burden or damage to tender skin, and the moisture of the skin is effectively kept.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a moisturizing and water-replenishing soluble cleansing paper and a preparation method thereof. Background technique [0002] Moisture is the first element of beautiful skin. Because the skin loses water, the water circulation of the skin is not smooth, the metabolism of the skin is slowed down, the blood vessels that supply the skin with nutrition shrink, the vitality of the epidermal cells is weakened, the subcutaneous fat is reduced, collagen, elastin, etc. are lost, and finally the formation of skin wrinkles can be caused. [0003] Chinese medicine cosmetology has a long history, and can regulate the human body as a whole, treating both symptoms and root causes. Traditional Chinese medicine can improve the water shortage state of the human body, thereby alleviating dry skin, itching, aging and other symptoms caused by water shortage. For example, "Rihuazi Materia Medica...
