Description

Technical Field

[0001] This invention relates to a makeup remover balm, its raw material composition, and its preparation method. Background Technology

[0002] With the rapid development of the cosmetics market, deep cleansing has become the first step in skincare, and makeup removal is being accepted by more and more consumers. Consumers' awareness of makeup removal has also changed significantly: people initially thought that they didn't need to remove makeup if they only applied sunscreen and primer, but now they believe that makeup removal products should also have characteristics such as skin care, high efficiency and precision, and a special skin feel.

[0003] Makeup removal is the process of removing makeup, sebum, and oil-soluble dirt from the skin's surface. It can effectively prevent clogged pores, skin aging, acne, and blackheads. Choosing a makeup remover that matches your skin type is the prerequisite for maintaining good skin condition.

[0004] Currently, the main mechanisms of action for makeup removers can be categorized into surfactant action and the principle of "like dissolves like." Surfactant action is a common mechanism in makeup removers. Nonionic surfactants, even at low concentrations, can reach the critical micelle concentration, existing in water as spherical micelles. When makeup remover comes into contact with a cotton pad, the hydrophilic heads of the surfactants contact the pad, while the hydrophobic tails align outwards. Upon contact with the skin surface, the hydrophobic chains dissolve makeup and dirt. Some of this is removed through friction, while the remaining dirt is dissolved within the micelle structure, forming a microemulsion under water rinsing to achieve a makeup removal effect. The principle of "like dissolves like" is a common mechanism in oil-based makeup removers. Leveraging the oil-dissolving property, the oils in the makeup remover formula remove makeup and oil-soluble dirt from the skin surface. Simultaneously, the surfactants in the formula achieve easy rinsing, emulsification, and residue-free results.

[0005] With the continued popularity of the concept of oil-based skincare, the idea of ​​using oils similar to the skin's lipid barrier to repair the skin barrier is gaining traction, leading to the increasing favor of cleansing oils and balms among consumers. Oil-based makeup removers can effectively remove stubborn makeup, but they require dry hands and a dry face to dissolve the makeup. For cleansing balms, improper selection of wax ingredients can result in a heavy, oily film, which can even lead to closed comedones. Furthermore, different wax ingredients can create different textures, such as mashed potato, ice cream, or fruit puree textures.

[0006] Compared to cleansing oils, cleansing balms are more convenient to use, and market expectations for these products focus on texture, feel on the skin, user experience, and makeup removal effectiveness. The texture needs to be soft and melt-in-your-mouth, leaving no oily film on the skin. The user experience should involve rapid emulsification upon contact with water, without causing stickiness or stinging in the eyes. Regarding makeup removal effectiveness, the goal is to remove basic makeup while also enhancing the removal of waterproof makeup such as mascara and eyeliner. In actual transportation, cleansing balms can experience issues like high-temperature melting and collapse, and low-temperature cracking. Therefore, the physicochemical stability of cleansing balms is a crucial factor to consider during formulation design.

[0007] Chinese patent CN115317387B discloses a cleansing balm formula that is refreshing and highly effective at removing makeup, but it still has limitations in terms of the target makeup removed and the issue of eye irritation during use. Chinese patent CN110664687B discloses a protective cleansing balm product; the active ingredients involved in the patent have significant skincare benefits, aligning with the current market concept of combining skincare and makeup removal. However, this patent also has shortcomings in terms of the target makeup removed, physicochemical stability, and the issue of eye irritation during use. Chinese patent application CN112675079A discloses a fast-emulsifying cleansing oil. This product features high refreshingness, strong emulsification ability, fast emulsification speed, and strong makeup removal power. The patent verifies the product's makeup removal power, emulsification ability, and skin irritation, but its physicochemical stability and user experience still need further verification.

[0008] Based on the current situation, there is an urgent need to develop a cleansing balm with excellent physicochemical stability, a superior user experience (especially no eye irritation during use), and the ability to remove waterproof makeup. Summary of the Invention

[0009] To overcome the technical shortcomings of existing cleansing balms in simultaneously achieving good physicochemical stability, user experience, and the ability to remove waterproof makeup, this invention provides a cleansing balm, its raw material composition, and a preparation method. Through optimization of the cleansing balm's raw material composition formula, a good balm texture is ensured while achieving excellent physicochemical stability and a pleasant user experience. It is particularly suitable for removing waterproof makeup and maintains excellent gentleness throughout use, without the eye-stinging problem found in existing cleansing balms.

Attached Figure Description

[0064] Figure 1 In Example 2, the scores of each indicator before and after use of the cleansing balms from Example 1, Comparative Example 4, and Comparative Example 6 are summarized. Detailed Implementation

[0065] The present invention is further illustrated below by way of embodiments, but the invention is not limited to the scope of the embodiments described herein. Experimental methods in the following embodiments that do not specify specific conditions were performed according to conventional methods and conditions, or as selected according to the product instructions.

[0066] The overall preparation method of the cleansing balm is as follows in the following examples and comparative examples:

[0067] S1. Mix biological surfactants, polyols, and deionized water to obtain the first phase;

[0068] S2. Mix fatty alcohol polyether surfactants and ester nonionic surfactants to obtain the second phase;

[0070] S4. At 85-100℃, add the second phase to the third phase, mix well, then add the first phase and antioxidant and stir to disperse evenly to obtain the makeup remover balm.

[0071] Furthermore, the specific filling method for the cleansing balm is as follows:

[0072] (1) Place the cleansing balm at 85℃, fill it with 50wt%-90wt% of cleansing balm, and then place it at 2-8℃ to cool and solidify for 5-20 minutes.

[0073] (2) Fill the remaining 10wt%-50wt% of the makeup remover balm, and then place it at 2-8℃ to cool and solidify for 20-60 minutes;

[0074] (3) Then transfer to room temperature and let stand for 6-24 hours.

[0075] Examples 1-11 and Comparative Examples 1-6

[0076] The corresponding cleansing balms were prepared according to the raw material composition formulas in Table 1 and the cleansing balm preparation method described above.

[0077] Table 1

[0078]

[0079]

[0080] The " / " in the table means that the component is not present in this embodiment or comparative example.

[0081] Example 1: Stability Test

[0082] Stability tests were conducted on the cleansing balms obtained in Examples 1-11 and Comparative Examples 1-6, respectively, as follows:

[0083] (1) Place the items at 50℃, 45℃, 25℃, 5℃ and -15℃ respectively for 3 months in the dark and observe whether they produce oil, sweat, collapse, etc.

[0084] (2) Place them at room temperature of 25°C under light conditions (light intensity of 15000Lx) for 3 months and observe whether they produce oil, sweat, collapse, etc.

[0085] (3) Place the items under cyclic conditions (3 days at 45℃ → 1 day at 25℃ → 3 days at -15℃), away from light, for 5 cycles, and observe whether they produce oil, sweat, collapse, etc.

[0086] The results are shown in Table 2.

[0087] Table 2

[0088]

[0089] The results showed that the cleansing balms in Examples 1-11 were all normal under high and low temperature for 3 months, light exposure for 3 months, and cyclic stability tests. They maintained a state similar to that under room temperature conditions and did not exhibit any obvious oiliness, sweating, or collapse. However, the cleansing balms in Comparative Examples 1-6 were relatively stable under room temperature and light conditions, but under extreme conditions, they all exhibited oiliness. In particular, under the three test conditions of 50℃, -15℃, and cyclic conditions, there was excessive oiliness that could not be absorbed back into the balm, which significantly affected its usability.

[0090] The above results indicate that both the fatty alcohol polyether surfactants and biological surfactants added in Examples 1-11 can effectively improve the stability of the cleansing balm under extreme conditions. In Comparative Examples 1-3 and Comparative Example 6, adding only a single fatty alcohol polyether surfactant or biological surfactant failed to improve the physicochemical stability of the cleansing balm (especially in Comparative Example 6, where the total surfactant content remained unchanged, this difference in effect still existed). In Comparative Examples 4-5, replacing the fatty alcohol polyether surfactants and biological surfactants with PEG-based nonionic surfactants, or not adding fatty alcohol polyether surfactants and biological surfactants, also failed to improve the physicochemical stability (especially in Comparative Example 5, where the total surfactant content remained unchanged, this difference in effect still existed).

[0091] Example 2: Performance Testing

[0092] For the cleansing balms obtained in Example 1, Comparative Example 4, and Comparative Example 6, the following performance tests were conducted during use and before and after use:

[0093] 1. Target Makeup: Select different types of makeup products to simulate the scene of heavy makeup in reality, in the following order: sunscreen (oil-in-water formula), long-lasting foundation (oil-in-water formula), long-lasting lipstick (pure oil-based formula), eyeliner (water-based film-forming formula), mascara (oil-based formula), and contour stick (oil-based formula).

[0094] 2. Number of participants: 10 volunteers who frequently use cleansing balm;

[0095] 3. Preparation before testing: Clean your hands and arms with facial cleanser, wipe them clean with absorbent paper, then apply a measured amount of the target makeup to the inside of your arm, let it sit at room temperature for 30 minutes, and let it air dry naturally to ensure that the makeup has completely formed a film on the inside of your arm.

[0096] 4. Scoring Indicators:

[0097] (1) Test on the spreadability and melting sensation of cleansing balm: Apply a certain amount of cleansing balm to the makeup area, massage in circular motions, and score the spreadability and melting sensation of the cleansing balm on the skin;

[0098] (2) Makeup dissolving power test: When the makeup remover balm comes into contact with makeup and is massaged in a circular motion, observe the makeup dissolving effect and score it;

[0099] (3) Hydrogel test: Take a certain amount of deionized water droplets and add them to the makeup area after massage and makeup dissolution, then massage in circles and score the resistance during the massage.

[0100] (4) Rinsing emulsification test: Rinse the area to be removed with water at a fixed flow rate and score the emulsification speed;

[0101] (5) Makeup removal power test: Massage for 20 circles in water with a fixed flow rate, and then score the makeup removal effect;

[0102] (6) Post-wash skin feel test: score the skin's freshness or residue feeling after washing;

[0103] (7) Mildness test: whether there are any uncomfortable symptoms such as eye irritation or stinging during the makeup removal process, and score accordingly;

[0104] The specific scoring criteria are shown in Table 3.

[0105] Table 3

[0106]

[0107] The results of the makeup dissolving power test are shown in Table 4.

[0108] Table 4

[0109]

[0110] The above-mentioned makeup-dissolving power test results show that, compared with Comparative Examples 4 and 6, the cleansing balm of Example 1 exhibits superior makeup-dissolving ability when dissolving different types of makeup. The target makeup products selected for this invention are all types of makeup that consumers have reported are difficult to remove, such as long-lasting foundations, long-lasting lipsticks, mascaras with high film-forming agent content, and water-based eyeliners that are currently difficult for cleansing balms to remove. The evaluation results of 10 volunteers show that the makeup-dissolving performance of Example 1 is significantly better than that of Comparative Examples 4 and 6. The main reason is the introduction of fatty alcohol polyether surfactants and biological surfactants, which effectively improve the makeup-dissolving ability of the cleansing balm for different types of makeup, making the makeup easier to remove from the skin and laying the foundation for subsequent makeup removal effects.

[0111] The results of the makeup removal power test are shown in Table 5.

[0112] Table 5

[0113]

[0114] The above makeup removal test results show that, compared with Comparative Examples 4 and 6, Example 1 showed better makeup removal ability for different types of makeup in the scores of 10 volunteers. The main reason is that when the cleansing balm is rinsed and emulsified with water and massaged, the surfactants in the formula will emulsify with water to form an oil-in-water emulsion, which makes the product have better rinsing properties. The fatty alcohol polyether surfactants and biological surfactants added in Example 1 can further improve the ability of the cleansing balm to bind with water, and accelerate the emulsification of oil and dirt on the skin surface into the oil-in-water emulsion, thereby further improving the makeup removal effect of the cleansing balm.

[0115] Furthermore, the present invention summarizes the aforementioned makeup dissolving power, makeup removing power, and related feelings during and after use in Table 6 below.

[0116] Table 6

[0117]

[0118] The results are shown in Table 6 and Figure 1 As shown in the results, the cleansing balm of Example 1 demonstrated superior user experience and makeup removal performance compared to Comparative Examples 4 and 6 in seven key indicators: initial melting sensation and makeup-dissolving power, rinsing gel and emulsification ability during use, post-use makeup removal power and skin feel, and gentleness. Furthermore, compared to Comparative Examples 4 and 6, the use of bio-surfactants in Example 1 effectively improved the gentleness of the cleansing balm during use.
