Problems solved by technology

Currently commercially available scrubs are usually made of insoluble solid abrasives, oil, water, and surfactants. Surfactants have a good descaling effect, but they are synthetic chemicals that have certain adverse effects on the skin.
[0003] There are also some types of scrubs now, such as August 21, 2013, the Chinese patent with the publication number CN103251536A, which discloses a kind of exfoliating loofah scrub, which contains the following components : Polymer glue 0.5-0.6kg, distilled water 40-42kg, old loofah pulp 9-10kg, Hangzhou chrysanthemum 1.8-2kg, olive oil 3-3.2kg, compound antibacterial agent 0.2-0.25kg, old loofah pulp has very thick plants Fiber, the scrub grinds the dried old loofah pulp into a coarse powder, the product is not fine enough, it is easy to cause damage to the skin, in addition, the formula of the scrub is complicated
Another example is that the publication date is June 18, 2014, and the publication number is CN103860438A Chinese patent, which discloses a whitening scrub made of grapefruit peel, which is mixed with grapefruit peel juice by adding grapefruit peel scrub Homogenize, add a small amount of konjac powder to make a paste, and then refrigerate below 10°C; pomelo peel scrub is made according to the following method: take fresh pomelo peel, wash it, blow it out, separate and remove the white inner soil in the pomelo peel, The thickness of pomelo peel is less than 1cm. Chop the pomelo peel, grind it to 80 mesh, add rosin with a fineness of over 80 mesh, and stir well; effect
Another example is that the publication date is October 16, 2013, and the publication number is CN103349642A Chinese patent, which discloses a plant natural moisturizing and gentle exfoliating edible sugar scrub, which contains the following components by weight percentage : 55-75% edible sugar, 10-20% moisturizer, 0.5-5% natural moisturizer, 0.5-5.0% plant natural moisturizer, 0.2-1.0% thickener and 0.01-3.0% Anti-sensitivity agent, and make up to 100% by water, the scrub effect of this edible sugar scrub is poor, and it does not have antibacterial and dirt-absorbing effects
[0004] To sum up, there is no skin care scrub with unique and simple formula, good scrubbing effect, excellent affinity to human skin, repairing and protecting skin, strong ability to absorb dirt, and antibacterial effect. Paste and its preparation method

Embodiment 1

[0026] The preparation method of the skin care scrub in the present embodiment comprises the following steps.

[0027] (1) Silkworm cocoons are peeled off and pupae removed to obtain the cocoon layer. With a mass percentage of 0.5% Na 2 CO 3 Scouring the cocoon layer with aqueous solution twice, 30 minutes each time, the scouring temperature is 100°C, and the liquor ratio is 1:100. After scouring, it is fully washed with distilled water and dried naturally to obtain silk fiber. With 50% CaCl by mass percentage 2 The aqueous solution dissolves the silk fiber, the dissolution temperature is 98°C, the bath ratio is 1:25, and the time is 5 minutes. The solution obtained after dissolving is poured into a cellulose dialysis membrane (molecular component 12,000-14,000), and dialyzed in running water for 3 days. The dialyzed solution was air-dried and concentrated to obtain an aqueous silk fibroin solution. Add water-soluble sericin (molecular weight 2×103 ), to a water-soluble ...

Embodiment 2

[0038] The preparation method of the skin care scrub in the present embodiment comprises the following steps.

[0039] (1) Dissolve silk fibroin fibers with calcium chloride, water and ethanol solution with a molar ratio of 1:8:2, the dissolution temperature is 70°C, the bath ratio is 1:25, and the time is 10 minutes. The solution obtained after dissolving is poured into a cellulose dialysis membrane (molecular component 12,000-14,000), and dialyzed in running water for 3 days. The dialyzed solution was air-dried and concentrated to obtain an aqueous silk fibroin solution. Add water-soluble sericin (molecular weight 5×10 3 ), to a water-soluble sericin concentration of 0.2% w / v, adding water-soluble carboxymethyl chitosan (molecular weight 5×10 4 , DSatO 0.5, DSatN 0.3), until the concentration of water-soluble carboxymethyl chitosan is 0.4% w / v, and then stand at 60°C until the solution becomes a translucent silk gel.

Embodiment 3

[0054] The preparation method of the skin care scrub in the present embodiment comprises the following steps.

[0055] (1) Silkworm cocoons are peeled off and pupae removed to obtain the cocoon layer. Scouring the cocoon layer twice with 0.4% neutral soap solution by mass, 1 hour each time, the scouring temperature is 100°C, and the bath ratio is 1:100. After scouring, it is fully washed with distilled water and dried naturally to obtain silk fiber. Use a ternary solvent mixed with lithium bromide, ethanol, and water at a weight ratio of 45:53:2 to heat and dissolve silk fibroin fibers at a temperature of 60°C. The bath ratio is 1:50. The solution obtained after dissolving is poured into a cellulose dialysis membrane (molecular component 12,000-14,000), and dialyzed in running water for 3 days. The dialyzed solution was air-dried and concentrated to obtain an aqueous silk fibroin solution. Add water-soluble sericin (molecular weight 6×10 4 ), to a water-soluble sericin co...

Abstract

The invention relates to skin-protecting facial scrub and a preparation method thereof. Currently, skin-protecting facial scrub with unique and simple formula and a preparation method thereof do not exist. The skin-protecting facial scrub is characterized by being prepared from fibroin gel and hull carbonized powder in a dose ratio of (10ml:1g)-(10ml:1.5g). The preparation method comprises the following steps: (1) adding gel accelerant into a 4-10%w / v silk fibroin aqueous solution, uniformly mixing, standing at 20-80 DEG C to obtain fibroin gel; (2) carbonizing rice hulls at 160-220 DEG C for 30-100 hours, grinding into powder, and screening through a screen of 80-100 meshes; (3) homogenizing the fibroin gel and the hull carbonized powder in a dose ratio of (10ml:1g)-(10ml:1.5g) into a paste so as to obtain the skin-protecting facial scrub. The skin-protecting facial scrub is unique and simple in formula, and has a good scrubbing effect.
