Embodiment 1－3

[0015] The formulations of Examples 1-3 are shown in Table 1.

[0016] Table 1:

[0017] raw material name

[0018] As far as the three examples in the above table are concerned, in addition to the effects of each component, relatively speaking, in example 1, the content of sorbitol is less, the content of hydrated silica is more, the cost of mask powder is low, and the amount of water required for reconciling mask powder The ratio of blended powder to water is about 1:2, the blending property is good, the transparency of the film is average, the skin tightening effect is good, the film can be peeled off completely, there is no film residue on the skin, and the skin surface coated with the film is not dry; in Example 2, the content of sorbitol increases, the content of hydrated silica decreases, the cost of mask powder is slightly higher, and the amount of water required for reconciling mask powder is slightly less. The ratio of reconciling powder to water is about ...

Embodiment 4

[0020] The following is a comparison of the data of the dry edge of the transparent mask prepared according to the ratio of Example 1 and the ordinary alginate powder mask after 15 minutes of application (generally, the application time of the powder mask is 15-20 minutes);

[0021] Test conditions: Indoor, room temperature 21°C, relative humidity 58%, mixing water is pure water, the ratio of powder to water when mixing is: 10 grams of powder plus 20 grams of water, the thickness of the mask is 1.5 mm; the timer is a stopwatch;

[0022] At the same position on the front of the left arms of 5 female subjects, draw a quadrilateral area (240 mm in circumference) with a length of 8 cm and a width of 4 cm, and apply the mask. At the minute, measure the edge length of the edge of the mask with dry edges (the width of the dry edge is greater than or equal to 0.5mm), record the value, and then compare; The edge length of the dry edge is measured separately, but due to the short interv...

[0036] The following is the comparison of the pH value of the ordinary mask powder and the new transparent mask powder, according to GB / T13531.1 Cosmetic general test method for the determination of pH value, dilution method, using the pHS-25 type produced by Shanghai Leici Chuangyi Instrument Co., Ltd. The acidity meter is used for detection, and the acidity meter is within the detection cycle.

Abstract

The invention provides transparent alginate mask powder capable of being peeled off wholly. The transparent alginate mask powder capable of being peeled off wholly comprises a film-forming agent, a coagulant, a retarder, a humectant and a bulking agent, but does not contain diatomaceous earth, talc powder and other mineral fillers. The mask powder has the pH value of 8.0 to 8.5, is transparent after being blended with water, and is relatively mild to skin when being used for skin care; and through addition of the humectant, not only the humectant effect is improved, but also a dry edge phenomenon caused by excessively fast moisture evaporation on the periphery of a mask is avoided.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a facial mask powder. Background technique [0002] At present, the peel-off mask powder sold on the market is mainly based on the basic principle of alginate as film-forming agent and calcium ion as coagulant, diatomaceous earth, starch (corn starch, potato starch, wheat starch, etc.), Water-insoluble powders such as talcum powder and kaolin are used as fillers. After mixing with water without adding pigments, the paste is opaque white. There are many defects in this kind of film powder, for example: when the film body is solidified, there will be white dry edges with a width of 0.5-2.0 mm around the film body. dry film. During the process of water evaporation, the edge of the film body shrinks and makes the skin itchy. When the film is peeled off, the dry edge is disconnected from the film body, leaving a lot of residue on the skin, which needs to be wiped off with...
