Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a washing and removing integrated bicontinuous phase makeup removing gel and a preparation method thereof.

Background

With the gradual popularization of sunscreen, isolation and color cosmetics products, common face cleaning products cannot meet the cleaning requirements of users before daily skin care, and the requirements of makeup removing products are increased. Particularly, after the makeup is popularized, the frequency of using the makeup by users is increased, the types of the used makeup products are changed, the waterproof and makeup removal preventing effects of the products are integrally enhanced, and the requirements of the users on makeup removal products are further increased.

Although the makeup removing product is mainly used for removing makeup, the makeup removing product belongs to skin care products. Makeup removal is the first step of a daily skin care procedure, and is usually a stubborn color makeup that cannot be completely removed by ordinary facial cleansers such as suntan lotion, foundation make-up, eye shadow, lipstick, mascara, and the like, before ordinary facial cleansing. Makeup removal is an extremely important link for beautifying and protecting skin, and if makeup removal is not thorough, pores can be blocked on the residual face of the makeup, so that the consequence is serious.

The makeup removing product is mainly divided into 5 types of makeup removing oil, makeup removing cream, makeup removing gel and makeup removing water according to the texture. Compared with the makeup removing liquid, the makeup removing cream and the makeup removing oil, the makeup removing gel has the best use feeling, does not need to be matched with makeup removing cotton due to the fact that the fluidity is too good like the makeup removing water, does not need to be further cleaned due to the fact that the makeup removing gel is greasy like the makeup removing oil after being used, and does not need to be further cleaned after being picked up by a stick and used like the makeup removing cream. For example, patent application 201410683413.4 provides a mild eye-lip cleansing gel and a preparation method thereof, wherein the gel comprises oil-soluble components and water-soluble components, and the eye-lip cleansing gel disclosed by the invention is light and water-moist in appearance, mild in chemical property, capable of thoroughly cleaning various makeup products, fresh and comfortable, and free of greasy feeling. However, the cleansing power of the eye and lip cleansing gel is general, and the cleansing effect is still not thorough. Patent application document 201710504241.3 provides a makeup removing cream gel and a preparation method thereof, wherein the preparation method comprises the steps of firstly forming a ternary decontamination microcapsule coating, then preparing the ternary decontamination microcapsule coating with squalane to obtain a microemulsion, and then stabilizing a system with acrylic resin to form a semitransparent makeup removing cream gel. The cleansing gel has strong cleansing ability, high safety, small irritation to eyes, easy rinsing, and moisturizing, moistening and non-greasy effects after use. However, the cleansing cream gel is poor in mildness and is not suitable for long-term use on low-tolerance skin.

In addition, most makeup removing products disclosed in the prior art can only remove water-soluble makeup or oil-soluble makeup, and cannot give consideration to multiple types of makeup removing products; meanwhile, the face can be completely cleaned only by being matched with subsequent face washing products. Therefore, it is necessary to research a makeup remover product with good removal effect on both water-soluble makeup and oil-soluble makeup.

Test example 1

Clean strength test on color cosmetics (BB cream, lipstick):

the left and right forearm were cleaned in a lump from 280 volunteers, and after the moisture was slightly absorbed by a paper towel, 3 test areas each having an area of 4cm by 4cm were marked at intervals of at least 2cm, and the 3 test areas were respectively numbered L1, L2, L3, R1, R2 and R3. After standing still for 20min, images of each test area were collected using a microscope, and the spectrophotometric instrument measured the L, a, b values of the skin after application of BB cream/lipstick.

The areas L1, L2, L3 and R1, R2, R3 were cleaned by a 1mL syringe using a commercially available facial cleanser, a commercially available cleansing water, and the cleansing gel prepared in examples 1-12, for 10 people per group. Then the mixture is washed clean by clear water and is slightly dried by paper towel. And standing for 30min, collecting images of the test areas by using a microscope, and measuring the values of L, a and b of the skin after makeup removal and cleaning by using a spectrophotometer. L represents the whiteness of black, the larger the value of L, the more white the skin, otherwise, the more black; a represents the red-green chroma, the skin is more red when the value of a is larger, and is more green when the value of a is larger; b indicates the degree of blue-yellow, and the larger the value of b indicates that the skin is more yellow, and conversely is blue. The laboratory keeps constant temperature and humidity, the testing temperature is 23-24 ℃, and the relative humidity is 50-60%.

The cleaning force calculation method comprises the following steps: calculating the skin color difference after applying BB cream/lipstick compared with the initial state, and recording as delta E (after applying); the skin color after makeup removal cleansing was poor compared to the initial state and was recorded as Δ E (after cleansing). The delta E can comprehensively reflect the three-dimensional change of skin chromaticity, the more the delta E value is, the more obvious the change of skin color is, the less the delta E value is, the closer the skin color is, the cleaning power is calculated through the delta E, and the calculation formula is as follows:

△E＝SQRT(△L*²+△a*²+△b*²)

cleaning power ═ Δ E (after application) - Δe (after cleaning)/Δe (after application)) × 100%

The results are shown in table 1(BB cream) and table 2 (lipstick):

100 volunteers were selected, 50 of which were dry skin subjects (randomly divided into 10 groups of 5 persons each) and 50 of which were oily skin subjects (randomly divided into 10 groups of 5 persons each), the skin oil content before each sample was used and the oil content after each group of samples was cleaned for the same time using a CBS skin analysis system at 25 ℃ in an environment of 25 ℃ with the fixed part of the cheek of the subject as a test area, the oil clearance was calculated according to the following formula and the arithmetic mean thereof was made, the cleaning effect of the product on oily skin and dry skin was examined, and the measurement results are shown in table 3.

TABLE 3

As can be seen from the data in Table 3: the data of dry skin testees show that the cleansing gel does not excessively remove facial grease, does not damage the skin barrier, basically does not harm the skin, does not cause skin dryness and difficulty, and is influenced by the formula composition of polyhydric alcohol and liquid grease; the data of oily skin testees show that the cleansing gel has better oil removal effect, the effect of combining washing and removing is realized, and the formula composition of the surfactant and the liquid oil can influence the cleansing gel.
