Description

[Technical Field]

[0001] This specification discloses a cleansing composition for makeup removal and facial cleansing. [Previous Technology]

[0002] With the increasing number of people wearing makeup, makeup removal has gradually become a more important factor than makeup application. Typically, makeup users first use makeup remover oil or similar products to remove makeup, and then use soap or facial cleanser for a double cleanse to remove any remaining oil or residue. To address the inconvenience of this double cleansing process, a cleansing composition was proposed in Korean Patent Publication No. 10-2002-0037206, but it was limited in its ability to remove makeup ingredients. Therefore, there is a real need to develop a composition that does not require double cleansing while still possessing excellent cleansing power. [Prior Art Documents] [Patent Documents]

[0038] Hereinafter, embodiments of the present disclosure will be described in detail. However, the following embodiments are merely examples to help fully understand the present disclosure, and the content of the present disclosure is not limited to the following embodiments. 1. Foaming power (bubble generation amount) evaluation method

[0039] 2g of the contents of the examples or comparative examples were applied to the hands and rubbed 10 times in running tap water at 25°C. The degree of foaming was then evaluated by sensory evaluation. Ten evaluators were selected, and scores were given according to the criteria in Table 1 below. The average score was then used for evaluation.

[0040] [Table 1] distinguish Bubble generation The density of the generated bubbles 5 points It foams very well The bubbles are very dense 4 points It foams better The bubbles are relatively dense 3 points Bubbling Bubbles 2 points It doesn't foam very well. The bubbles are relatively few 1 point Poor foaming The bubbles are very rare. 2. Evaluation method for spreadability (rolling sensation)

[0041] The contents of 2g of the examples or comparative examples were rubbed on the back of the hand 10 times, and the degree of rubbing without feeling any resistance was evaluated. Ten expert evaluators were selected, and scores were given according to the criteria in Table 2 below. The average score was used for evaluation.

[0042] [Table 2] distinguish Smearable 5 points It spreads very well 4 points Good spreadability 3 points The spreadability is average. 2 points Poor spreadability 1 point It has very poor spreadability. 3. Stability Evaluation Methods

[0043] A small amount of the contents of the examples or comparative examples was placed on a glass slide, a coverslip was placed on top, and a certain amount of force was applied to spread it evenly. It was observed using an optical microscope (ECLIPSE NI-U, Nikon) at 40x magnification. The stability was evaluated based on whether the hydrophilic portions of the hydrophilic portion and the hydrophobic portions of the hydrophobic portion of the contents were necessarily arranged to form a layered structure.

[0044] Figure 1a is an example of a state in which the particles of the contents form a layered structure, in which case it can be evaluated as stable (indicated by ○). Figure 1b is an example of a state in which the particles of the contents do not form a layered structure, in which case it can be evaluated as unstable (indicated by ×). 4. Cleanliness Evaluation Method (1) Test Preparation

[0045] A 2cm × 2cm area was marked on artificial leather (BIOSKIN PLATE, Beaulax) with paper tape, and the cosmetic sample was applied and dried for 1 hour. (2) Test method

[0046] After dripping 0.5g of the contents of the example or comparative example into the above 2cm×2cm area, rub it in a circular motion with your index finger 20 times. Then, cover it with a wiping paper (wipeall, manufactured by Yuhan-Kimberly) to prevent it from being wiped by physical force, and gently press with your palm to wipe away the oil and residue. Dry in this state for more than 1 hour. (3) Result confirmation

[0047] A colorimeter (Chroma Meter, CR-300 spectrophotometer, Konica Minolta) was used in the lightbox (acrylic sheet material) to measure the color difference at a certain ratio. The artificial leather before makeup, the artificial leather after makeup, and the artificial leather after cleaning were measured three times. The average value was substituted into the following mathematical formula 1 to calculate the color difference (ΔE (Lab)). [Mathematical formula] E1 = the color difference between the artificial leather before makeup and the artificial leather after makeup E2 = the color difference between the artificial leather after makeup and the artificial leather after cleaning "L*", "a*" and "b*" represent "lightness", "color opponent green-red" and "color opponent blue-yellow" respectively. For example, the blue sample has a negative b* value, while the red sample has a positive a* value. If there is a higher positive or negative value, the color is stronger. (4) Evaluation criteria

[0048] Substitute the calculated color differences E1 and E2 into the following mathematical formula 2 to obtain the cleaning power value. [Mathematical Formula 2]

[0049] The collected cleaning power values ​​were scored between 1 and 5 points based on the scores in Table 3 below, and the cleaning power was evaluated.
