Description

Nicotinamide capsule mask and preparation and use methods thereof

Technical Field

The invention relates to the technical field of skin care products, in particular to a nicotinamide capsule mask and a preparation method and a using method thereof.

Background

The facial mask is a category of skin care products, is a carrier of a beauty maintaining product, and is applied on the face for moisturizing, whitening, resisting aging, balancing grease and other beauty functions. The facial mask mainly has the forms of a paste type, a tearing type, a jelly type and a wet tissue type; the mud paste type facial mask is commonly an alga facial mask, a mud facial mask and the like, the tearing type facial mask is commonly a special nasal paste for blackhead, the jelly glue type facial mask is mainly a sleep facial mask, and the wet tissue type facial mask is generally a facial mask paper which is packaged in a single piece and is soaked with beauty fluid; among them, the wet tissue type mask is widely used because of its convenient use and comprehensive efficacy.

In the prior art, a patent application publication number of CN107684536A discloses a whitening and moisturizing mask and a preparation method thereof, wherein the mask comprises the following components in parts by weight: 100 parts of water, 8-12 parts of humectant, 2-5 parts of thickener, 0.05-0.1 part of preservative, 4-6 parts of solubilizer, 5-8 parts of nicotinamide, 5-10 parts of lanolin, 2-5 parts of glycerol polymethacrylate, 10-15 parts of polygonum cuspidatum extract, 3-5 parts of chamomile flower extract, 10-15 parts of tea extract, 15-20 parts of glycyrrhiza glabra root extract, 8-10 parts of scutellaria baicalensis extract, 10-20 parts of rosemary extract, 5-10 parts of tocopherol and 8-10 parts of panthenol.

The nicotinamide added in the mask is also called nicotinamide, is a derivative of vitamin B3, has the main effects of relieving and preventing the problems of dark and yellow skin color and the like generated in the early aging process of skin in the aspect of skin anti-aging, repairing the damaged barrier of the skin, improving the resistance of the skin, reducing the transfer amount of melanin to surface cells and having remarkable whitening effect. However, for some people with sensitive skin, allergy phenomena such as skin redness, itching and stabbing pain can occur when products containing nicotinamide are used, and the allergy phenomena are more likely to occur particularly under cold and dry weather conditions. The irritation of niacinamide to some people is caused by niacin in niacinamide, which is most stable in pH 6 environment, but is hydrolyzed to form niacin in pH higher or lower than 6, resulting in skin allergy. Although the whitening effect on the skin is better as the addition amount of the nicotinamide is increased in a certain addition range, the skin irritation is more obvious. Therefore, it is desired to provide a mask which can whiten and moisturize skin and has little irritation to the skin.

Performance testing

Sensory, physicochemical, and hygienic indicators of the masks of examples 1 to 5 were measured according to the QB/T2872-2017 facial mask requirements, and the results are shown in Table 3.

Table 3 sensory, physicochemical and hygiene test charts of the masks of examples 1 to 5

According to data in table 3, the facial mask prepared by the invention meets the requirements of sensory indexes, physical and chemical indexes and sanitary indexes in the national execution standard QB/T2872-2017 facial mask.

Preparing masks by the methods of examples 1-5 and comparative examples 1-3 respectively, dividing the masks into AB groups as samples, and storing the mask of group A for 3 days at 25 ℃ and 65% RH; placing the group B facial mask in a circulation box at the temperature of-5-40 ℃ for 3 months for use.

The using method comprises the following steps: adding the stock solution of the mask into the mask solution, mixing the stock solution with the mask solution, and soaking the membrane cloth; then applying the membrane cloth on the cleaned face, taking off the membrane cloth for 15min, and cleaning the face with clear water.

The evaluation method comprises the following steps: randomly selecting female volunteers of 20-35 years old, dividing the female volunteers into 16 groups, using facial masks of the group A and the group B respectively for 10 persons in each group, using the same lotion only containing moisturizing components for the volunteers except cosmetic water every day, applying the facial masks every 3 days with the test period of 30 days, testing the skin of the volunteers by using a skin tester before and after the test, wherein the test time is the same, and the test items are skin irritation condition, skin water content change rate, skin oil secretion change rate, skin roughness change rate and skin whitening degree change rate; the skin irritation condition is that when the facial mask is used, the skin generates abnormal phenomena such as red blood streak, pruritus, red swelling, stabbing pain and the like, if the abnormal phenomena occur, the test is not performed, the skin state of each group of volunteers is recorded, and the average value of the test results is shown in table 4.

Table 4 mask performance test tables of examples 1 to 5 and comparative examples 1 to 3

According to the data in table 4, compared with the traditional mask, the mask prepared by the invention has small stimulation and good whitening and moisturizing effects; in the B group test, the facial mask still keeps good stability, and has good whitening, moisturizing and low irritation to the skin.

Compared with the example 1, in the A group test, the whitening and moisturizing effect of the facial mask of the comparative example 2 on the skin is slightly reduced, but the facial mask still has no obvious irritation on the skin, and in the B group test, the facial mask of the comparative example 3 not only has the obviously reduced whitening and moisturizing effect on the skin, but also has the obviously increased number of the skin allergic volunteers, which shows that the addition of the plant soothing agent and the skin conditioning agent can improve the stability of a product system to a certain extent and reduce the irritation of nicotinamide on the skin due to hydrolysis.

The stock solution of comparative example 3 did not contain a plant preservative and VB3 capsule particles; compared with example 1, in the group a test, the whitening and moisturizing effect on the skin of the comparative example 3 is slightly reduced, but still no obvious irritation on the skin, and in the group B test, the whitening and moisturizing effect on the skin of the facial mask of the comparative example 3 is obviously reduced, and the number of skin allergic volunteers is obviously increased, which shows that the stability of a product system can be obviously improved and the irritation on the skin caused by the hydrolysis of nicotinamide can be reduced by adding the plant preservative and the VB3 capsule particles.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
