The preparation process was also identical to that of example 1.

Example 5

The present example provides a gel face mask comprising a face mask cloth (cotton fiber face mask cloth) and a gel composition (the same formulation as in example 1) carried on the face mask cloth.

The preparation process was also identical to that of example 1.

Example 6

The present example provides a gel face mask comprising a face mask cloth (lyocell fabric face mask cloth) and a gel composition (the same formulation as in example 1) carried on the face mask cloth.

The preparation process was also identical to that of example 1.

Example 7

The present example provides a gel face mask comprising a mask cloth (ultrafine fiber mask cloth) and a gel composition (the same formulation as in example 1) carried on the mask cloth.

The preparation process was also identical to that of example 1.

Example 8

The present example provides a gel face mask comprising a face mask cloth (lyocell fiber and ultrafine fiber composite face mask cloth) and a gel composition (the formulation is shown in the following table, and the type of water-soluble thickener is replaced in comparison with example 1) carried on the face mask cloth.

The preparation was identical to that of example 1 (the viscosity of the gel composition was 1300 mPa.s and the pH was 7.3).

Example 9

/>

The preparation process was identical to that of example 1 (the viscosity of the gel composition was 6800 mPas and the pH was 6.35). However, because the water-soluble thickener does not contain hydroxyethyl cellulose, the softening effect of the gel composition on the mask cloth is slightly poor, and the softness and the skin adhesion of the mask cloth are slightly poor when the gel composition is used as a whole.

Example 10

/>

The preparation was identical to that of example 1 (the viscosity of the gel composition was 1200 mPa.s and the pH was 7.8). Wherein the acrylamide-dimethyl taurate/VP copolymer can thicken by itself, and the pH of the system can be increased after arginine is added without neutralizing and thickening by arginine.

Example 11

The present example provides a gel face mask comprising a mask cloth (lyocell and ultrafine fiber composite mask cloth) and a gel composition (formulation shown in the following table, differing from example 1 only in that the percentage of thickener is excessive) carried on the mask cloth.

The preparation process was identical to that of example 1 (the viscosity of the gel composition was 28500 mPa.s and the pH was 6.5).

Example 12

The present example provides a gel face mask comprising a mask cloth (lyocell and ultrafine fiber composite mask cloth) and a gel composition (formulation shown in the following table, differing from example 1 only in that the percentage of thickener is too small) carried on the mask cloth.

The preparation was identical to that of example 1 (the viscosity of the gel composition was 1300 mPa.s and the pH was 7.9). The softness and skin-sticking property of the membrane cloth are slightly deteriorated due to the reduced amount of hydroxyethyl cellulose in the water-soluble thickener.

Evaluation test:

(1) Transparency evaluation

The jelly face patches prepared in examples 1, 4-7 were selected to have the same gram weights, and were tiled on a colored substrate for visual inspection. As shown in fig. 1: the A-E are sequentially lyocell fiber and superfine fiber composite mask cloth, bamboo fiber mask cloth, cotton fiber mask cloth, lyocell fiber mask cloth and superfine fiber mask cloth. As can be seen from the figure: the transparency of the gel facial mask prepared by the lyocell fiber and superfine fiber composite facial mask cloth is obviously superior to that of the gel facial mask prepared by other types of facial mask cloth.

(2) Evaluation of mechanical Properties (softness, skin-contact Property and stretch resistance)

The operation method comprises the following steps: 60 female volunteers aged 18-35 were selected and tested for the products of examples 1-12, 5 individuals per group. After the face is cleaned, the mask is taken out and spread on the face, the eyes and the nose are aligned, the lips are aligned, the mask is pressed lightly to be clung to the face, after the mask is statically applied for 20min, the mask is taken out, and the rest essence is taken out and is absorbed by the whole face and the neck without cleaning.

The evaluation method comprises the following steps: 4-5 are classified as "very satisfactory", 3-4 are classified as "satisfactory", 2-3 are classified as "general", 1-2 are classified as "less satisfactory", and 0-1 are classified as "unsatisfactory".

The test results are shown in table 1 (data in table are scoring averages after trial of 5 volunteers):

TABLE 1

Group of	Softness	Skin-sticking property	Stretch resistance
				Example 1	5	5	5
Example 2	5	5	5
				Example 3	5	5	4.2
Example 4	5	5	5
				Example 5	5	5	5

				Example 9	3	3	5
Example 10	5	5	3.5
				Example 11	5	5	2.5
Example 12	3.5	3.5	5

From the results in Table 1, it can be seen that: the gel face mask has good softness, skin-sticking performance and stretching resistance, wherein the addition of hydroxyethyl cellulose has great influence on the softness, skin-sticking performance and stretching resistance of the mask cloth. When the addition amount is low, the film cloth has poor softness and skin adhesion, good stretching resistance and difficult deformation; when the amount of the additive is relatively high, the film cloth is excellent in flexibility and skin adhesion, but is poor in tensile properties and is easily deformed.

(3) Mask cloth tape liquid amount evaluation

The liquid amount of the mask cloth belt, namely the weight of the mask cloth for absorbing essence/the weight of the mask cloth, characterizes the liquid holding capacity of the mask cloth for absorbing the essence, and the higher the liquid carrying rate is, the stronger the capacity of absorbing the essence is, the liquid is not easy to drip and dry, and meanwhile, full essence feeling can be brought to consumers.

The operation method comprises the following steps:

1. weigh the weight m of the single piece of membrane cloth ₀ ；

2. Equal amounts of the gel compositions m prepared in examples 1-12 were added to a beaker ₁ ；

3. Soaking the membrane cloth in the gel composition for 30min, and fully saturating;

4. taking out the membrane cloth by using tweezers, standing the membrane cloth perpendicular to a beaker until the membrane cloth does not drip in 30 seconds, and reading the weight m of the essence in the beaker ₂ ；

5. Calculate mask strap liquid volume= (m) ₁ -m ₂ )/m ₀ 。

The test results are shown in table 2:

TABLE 2

/>

As can be seen from the data in table 2: the gel face mask has higher liquid carrying amount, the thickness degree of the gel composition influences the liquid carrying amount of the mask, and the type of the mask also influences the liquid carrying amount of the mask.

(4) Evaluation of permeability

The permeability of the mask characterizes the capability of the mask cloth to release essence, and the better the permeability is, the stronger the capability of releasing the essence is, the more nutrition is absorbed by skin, and the better the skin feel and effect after use are.

The operation method comprises the following steps:

60 female volunteers aged 18-35 were selected and tested for the products of examples 1-12, 5 individuals per group. After the face is cleaned, the mask is taken out and spread on the face, the eyes and the nose are aligned, the lips are aligned, the mask is pressed lightly to be clung to the face, after the mask is statically applied for 20min, the mask is taken out, and the rest essence is taken out and is absorbed by the whole face and the neck without cleaning.

The test results are shown in table 3 (data in table are scoring averages after trial of 5 volunteers):

As can be seen from the data in table 3: the gel facial mask has good permeability, and the thinness degree of the gel composition and the material of the mask cloth can influence the overall permeability of the mask.

(5) Evaluation of skin moisturizing Effect

The operation method comprises the following steps:

1) After 36 volunteers (three volunteers are randomly allocated to each group of products of women, ages 18-35 and 12 groups for use) are selected for cleaning, the mask is taken out and spread on the face, the eyes and nose parts are aligned, the lips are aligned, the mask is pressed lightly to be clung to the face, after the mask is applied for 15min, the mask is taken lightly, and the rest essence is taken by tapping the whole face and neck until the mask is absorbed, so that cleaning is not needed. Skin moisture tester after waiting for 15min

CM 825 determines skin stratum corneum moisture content.

2) Stratum corneum moisture content: each volunteer was tested 3 times using a Corneometer and the final results were presented as an average of three volunteers.

Parameter interpretation: the larger the parameter value, the higher the moisture content of the skin horny layer.

And (3) result judgment: after the product is used, the moisture content value of the stratum corneum of the test area is increased compared with that before the product is used, so that the test sample has a moisturizing effect; the larger the improvement rate is, the better the moisturizing effect of the test sample is.

The results are shown in Table 4:

Example 12	43.5	58.4	34.25

As can be seen from the data in table 4: the gel facial mask has a very good moisturizing effect, and the thin and thick degree of the gel composition and the material of the mask cloth can influence the overall moisturizing effect of the mask.

(6) Evaluation of skin lightening Effect

The operation method comprises the following steps:

1) After 36 volunteers (three volunteers are randomly allocated to each group of products of women, ages 18-35 and 12 groups for use) are selected for cleaning, the mask is taken out and spread on the face, the eyes and nose parts are aligned, the lips are aligned, the mask is pressed lightly to be clung to the face, after the mask is applied for 15min, the mask is taken lightly, and the rest essence is taken by tapping the whole face and neck until the mask is absorbed, so that cleaning is not needed. Skin gloss was measured after 15min of rest using a skin gloss tester glossmeter GL 200.

2) Skin gloss: each volunteer was tested 3 times using a Glossymeter and the final results were presented as an average of three volunteers.

Parameter interpretation: the greater the value of the gloss parameter, the better the skin gloss.

And (3) result judgment: after the product is used, the glossiness value of the test area is increased compared with that before the product is used, which indicates that the test sample has the effect of improving the glossiness of the skin; the greater the improvement rate, the better the skin gloss improvement effect of the test sample. The results are shown in Table 5:

TABLE 5

As can be seen from the data in table 5: the gel facial mask has a very good effect of improving the skin glossiness, and the thinness degree of the gel composition and the material of the mask cloth can influence the overall effect of the mask.
