Description

A kind of foam sheet mask

technical field

The invention relates to the technical field of cosmetics, in particular to a foaming sheet mask.

Background technique

Sheet masks are popular cosmetics that are popular among consumers and have been integrated into the basic process of consumers' skin care. The sheet mask usually consists of 3 parts, namely mask liquid, mask cloth and packaging bag. The mask liquid is the basis for realizing various functions of the mask. The mask cloth carries and holds the mask liquid to assist the mask to achieve the desired skin care effect, and the packaging bag is necessary for safe storage of the mask liquid and mask cloth.

Sheet masks can provide a variety of skin care effects. Consumers in the cosmetics market claim to pay attention to sheet masks such as hydration, moisturizing, brightening, moisturizing, firming, oil control, etc., to name a few. It has always been the goal of cosmetics developers to help consumers realize their beauty dreams and provide safe, effective and novel cosmetics.

Foaming sheet mask is a mask product that can produce spontaneous foam and has multiple effects such as cleaning, massaging, moisturizing, and brightening. Different from ordinary sheet mask products, foam sheet mask products have the effect of cleansing and renewing cuticles. In order to meet consumers' habits of using sheet masks, foaming sheet masks need to stay on the skin for about 15 minutes. In this case, it is necessary to consider not only the density and durability of the foam, but also the safety of the product. The time for the sheet mask to seal the skin is much longer than the time required for usual cleansing. Prolonged contact with surfactants under closed conditions will bring great pressure to the skin.

Detailed ways

In order to better illustrate the purpose, technical solutions and advantages of the present invention, the present invention is further illustrated by the following examples. It should be understood that the embodiments of the present invention are only used to illustrate the technical effect of the present invention, and are not used to limit the protection scope of the present invention. In the examples, the methods used are conventional methods unless otherwise specified. Meanwhile, in the examples, the materials and reagents used can be obtained from commercial sources unless otherwise specified.

The invention uses the CAMVA chicken embryo chorioallantoic membrane test to carry out the irritation test and evaluation of raw materials and formulas. The basic principle of CAMVA is to use the chorioallantoic membrane (CAM) blood vessels in the fertilized egg embryos (chicken embryos, duck embryos, goose embryos and other fertilized embryos that are easy to culture and observe) that have been incubated for 10 to 14 days to have a composition similar to that of human conjunctival blood vessels. Features, by directional stimulation of CAM blood vessels with stimulants, observing the changes in blood vessels and their surrounding tissues, simulating the stimulation damage of human conjunctival blood vessels by the stimulants to be tested, and giving a stimulation score according to the degree of vascular damage on the CAM, the final determination The stimulus value range of the product. The CAMVA scoring criteria are shown in Table 1 below.

Table 1 Scoring Criteria

Notes:

1. Ghost blood vessels: refer to blood vessels without blood perfusion in the blood vessels

2. Congestion: Refers to the phenomenon of blood filling caused by stagnant blood flow in blood vessels or blood vessel swelling

3. Bleeding: blood flows out of the blood vessel from the blood vessel, which can appear in various forms such as spotting or flocculent diffuse bleeding outside the blood vessel, and is scored according to the reaction in the test circle.

According to the average size (ie NC value) of the vascular damage score, the stimulus size of the test substance is compared, and the evaluation criteria are shown in Table 2 below.

Table 2 Evaluation Criteria

The irritation substitution test of the present invention uses SPF grade White Leghom chicken fertilized chicken embryos, hatches for 10 days, opens the shell to expose the CAM membrane and places an O-ring, directly adds different test substances into the ring, and incubates at 37°C After 30 minutes, observe and take pictures to record the changes in blood vessels, observe and count the number of chicken embryos with positive reactions (congestion, ghost blood vessels, bleeding, etc.). 0.9% normal saline was used as a negative control, and 3 chicken embryos were tested for each batch of SPF grade fertilized chicken embryos. The test substance was tested on 10 fertilized chicken embryos, one highest score and one lowest score were removed, and the average score of the remaining 8 fertilized chicken embryos was calculated to obtain the NC value of the test substance. According to the practical experience in the market, the NC value of the facial mask liquid should be ≤3, so that the irritating effect of such a facial mask liquid has a good market acceptance. The present invention evaluates the mildness of the foaming sheet mask and adopts this empirical value as the criterion.

The facial mask liquid of the foaming sheet mask containing the above-mentioned preferred betaine-based and imidazoline-based amphoteric surfactants was subjected to an extraordinary stability test, taken out at 1 day and 28 days, and returned to room temperature to observe the change in appearance. The results are shown in Tables 6 and 7 below.

Table 6 Contains preferred betaines and imidazolines foaming sheet mask's facial mask liquid 1 day super-conventional stability

Table 16 is added with the experimental group formula of mask cloth softening agent

For the preparation process of the above formula, refer to the preparation process in Table 5 in Example 1.

The difference between the control group and the experimental group is only: the control group does not add facial mask cloth softener.

Table 17 shows the evaluation results of users on the facial masks of the above-mentioned experimental group and control group.

Table 17 Evaluation Results

group Soft and good fit Good ductility Experimental group (with mask fabric softener) 87/100 85/100 Control group (without mask cloth softener) 62/100 56/100

It can be seen from the results in Table 17 that the use of mask fabric softener can significantly improve the softness and flexibility of the mask, thereby improving the comfort of the mask.

The screening of embodiment 6 mask cloth

The facial mask cloth of the present invention can be selected from at least one of natural fibers, chemical fibers, and blended fibers, and the facial mask cloth is a non-mesh dense unidirectional weaving method or a cross-laid weaving method.

Screening experiments of mask cloths of different materials and weaving methods are shown in Figures 15-16, and the formula of the mask liquid used is shown in Table 18.
