Problems solved by technology

[0005] It usually takes 10 to 30 minutes to apply the mask, but due to the evaporation of the mask moisture, the temperature of the mask and facial skin drops, which not only slows down the delivery of nutrients from the mask to the skin, but also causes capillaries to shrink and pores to shrink due to the drop in skin temperature. Occlusion, which eventually leads to a reduction in cosmetic effect
Marketed masks usually overcome this defect by increasing the content of active ingredients in the mask or using drugs that dilate blood vessels, but this also increases the risk of skin allergies
Not only that, applying a mask will also cause the microcirculation of the body surface to be disturbed by the drop in skin temperature, and the local blood vessels that nourish the nerves will spasm, resulting in ischemia, edema, and compression of the nerve tissue, which may easily cause facial paralysis

Embodiment 1

[0038] Embodiment one: the synthesis of lanthanum boride

[0039] Dissolve sodium borohydride in a sufficient amount of tetrahydrofuran (THF) in a ball mill jar to form a saturated solution, then weigh lanthanum hydroxide (0.19 g) and sodium borohydride (0.227g) powders are added to a ball mill jar, and after ball milling at 400 rpm for 2 hours, a paste is formed, placed in a reactor, heated at 120° C. for 30 minutes to evaporate the solvent THF, to obtain lanthanum hydroxide and A mechanical mixture of sodium borohydride, heating at a rate of 2°C / min, heating to 500°C and holding for 2 hours, releasing hydrogen, cooling to room temperature and then washing with water. During washing, sodium oxide reacts with water to form sodium hydroxide, which dissolves in water , centrifuged, and vacuum-dried at 80°C to obtain nano single-crystal lanthanum boride.

Embodiment 2

[0040] Example 2: Synthesis of thin-walled silica-coated nano single crystal lanthanum boride

[0041]In 90 milliliters of ethanol, add 1 milliliter of ammoniacal liquor (mass concentration is 30wt%) successively and continue stirring for 30 minutes to form a homogeneous solution, then dropwise add 0.1 gram of tetraethyl orthosilicate, and ultrasonically disperse for 40 minutes to form A solution; 10 milliliters of ammoniacal liquor ( Mass concentration is 30wt%) to 20 milliliters of ethanol, then add 10 milliliters of deionized water and 2 grams of monocrystalline lanthanum boride obtained in Example 1 to form a suspension; A solution is added dropwise to the suspension , carry out silica coating; stir for 12 hours, the coating is completed, and centrifuge to obtain thin-walled silica-coated nano single-crystal lanthanum boride.

Embodiment 3

[0042] Example 3: Synthesis of thickened silicon dioxide-coated nano single crystal lanthanum boride

[0043] In 90 milliliters of ethanol, add 2.5 milliliters of ammoniacal liquor (mass concentration is 30wt%) successively and continue to stir for 30min to form a homogeneous solution, then dropwise add 0.25 grams of tetraethyl orthosilicate, ultrasonic dispersion 40 minutes, form A solution; 10 milliliters of ammoniacal liquor ( Mass concentration is 30wt%) to 20 milliliters of ethanol, then add 10 milliliters of deionized water and 2 grams of monocrystalline lanthanum boride obtained in Example 1 to form a suspension; A solution is added dropwise to the suspension , carry out silica coating; stir for 12 hours, the coating is completed, and centrifuge to obtain thickened silica-coated nano single-crystal lanthanum boride.

Abstract

The invention relates to the field of cosmetic facial masks and aims to provide a preparation method of a synergistic cosmetic facial mask for improving blood circulation. Including: after ball milling and heating reaction of lanthanum hydroxide and sodium borohydride, washing, separating and drying to obtain nano single crystal lanthanum boride, and then preparing nano single crystal lanthanum boride coated with silicon dioxide; Silicon-coated nano single crystal lanthanum boride and gelatin solution are ultrasonically dispersed and mixed to form a suspension, sprayed on one side of the non-woven fabric and dried; gelatin solution is sprayed on the other side of the non-woven fabric and dried to obtain synergy type beauty mask. Since the present invention strengthens the mass transfer of nutritional ingredients, the amount of nutritional ingredients used is greatly reduced, thereby reducing the risk of skin allergies. By using the photothermal effect, the cooling of the facial skin caused by the mask is avoided, especially in winter, which can effectively reduce the risk of facial paralysis. The facial mask can be stored in a dry state, has a long shelf life, and is beneficial to commercialization.

Description

technical field [0001] The invention relates to the field of cosmetic facial masks, in particular to a preparation method of a synergistic cosmetic facial mask for improving blood circulation. Background technique [0002] Mask is a category of skin care products. It is made by loading beauty care ingredients on kaolin and other carriers, and coating them on non-woven fabrics, silk masks, tencel masks, bio-cellulose masks, and non-woven fabrics. Masks are widely used, and their most basic and important purpose is to make up for the insufficient cleansing work of makeup remover and face wash. On this basis, they can be combined with other essence ingredients to achieve other maintenance functions, such as moisturizing, whitening, anti-aging, balancing oil, etc. Wait. [0003] The beauty principle of the mask is to use the short time covered on the face to temporarily isolate the outside air and pollution, increase the temperature of the skin, expand the pores of the skin, pr...
