Description

Technical Field

[0001] This invention relates to a composition preferably used for cleaning keratin materials and / or removing makeup from keratin materials. The invention also relates to a non-therapeutic method of using said composition to clean keratin materials and / or remove makeup from keratin materials. Background Technology

[0002] Cleansing or removing makeup from the skin is crucial for skincare. In particular, it is essential for consumers of makeup products to have an effective makeup remover. It must be as effective as possible because oily residues, such as dirt, excess sebum, and residues from daily makeup and color-safe products (especially waterproof products), can accumulate in skin folds and clog pores, potentially leading to blemishes.

[0003] Several types of skin cleansing or makeup removal products are known, such as two-phase makeup removers, makeup remover water, makeup remover balm, and makeup remover milk.

[0004] Two-phase makeup removers are effective, but inconvenient to use because they need to be shaken before each use, and the two phases are consumed at different rates. Makeup remover water and micellar lotion leave a refreshing feeling, but are also inconvenient because they may drip due to their low viscosity.

[0005] Makeup is primarily composed of hydrophobic substances used for long-lasting effects. It is difficult to remove with hydrophilic compositions. Therefore, makeup removers must contain hydrophobic substances as solvents, such as plant oils, hydrocarbon oils, fatty esters, fatty alcohols, and silicone oils.

[0006] However, if the makeup remover contains a higher amount of oil, it is difficult for the makeup remover to stabilize because the oil droplets cannot hold their positions due to aging or temperature changes, and they subsequently collapse, causing leakage.

[0007] Therefore, a stable composition is needed for removing makeup from keratin materials. Invention Overview The inventors have discovered that such a requirement can be achieved through this invention.

[0009] Therefore, according to one aspect, the present invention relates to a composition preferably used for cleaning keratin materials and / or removing makeup from keratin materials, comprising: (i) at least one glycolipid; (ii) at least one alkyl sulfosuccinate salt; and (iii) At least 10% by weight of at least one oil relative to the total weight of the composition.

[0010] The composition according to the invention is stable.

[0011] According to another aspect, the present invention provides a non-therapeutic method for cleaning keratinous materials (particularly skin) and / or removing makeup from keratinous materials (particularly skin), comprising applying a composition according to the invention to the keratinous material (particularly skin) and washing off the composition after an optional period of time.

[0116] The composition of Comparative Example 1 does not contain glycolipids.

[0117] The composition of Comparative Example 2 does not contain alkyl sulfosuccinate salts.

[0118] The composition of Comparative Example 3 does not contain oil.

[0119] The composition of Comparative Example 4 does not contain at least 10% by weight of oil.

[0120] Preparation process The composition is prepared as follows.

[0121] Mix all raw materials and add water to bring the total weight to 100% to obtain a mixture. Next, heat the mixture to 60°C with stirring and then cool it to 30°C.

[0122] Evaluate Evaluate the stability, appearance, and viscosity of each composition prepared above.

[0123] stability Each composition was filled into four 100 ml glass vials and placed at room temperature (25°C), 45°C, 4°C, and cyclically (one cycle: 6 hours at 20°C, 6 hours lowered to -20°C, 6 hours at -20°C, 6 hours raised to 20°C). The separation of each composition was then checked on days 2, 6, and 11.

[0124] If the test composition does not separate on days 2, 6, and 11, the test composition is considered stable; otherwise, it is unstable.

[0125] Appearance The appearance of each of the above compositions was observed with the naked eye immediately after their preparation.

[0126] Viscosity The viscosity of each composition was measured at 25°C immediately after preparation using a Rheomat R180 viscometer equipped with an M4 rotor. The measurement was performed at a shear rate of 200 rpm after the rotor had been rotating in the sample for 10 minutes (after which the viscosity and rotor rotation speed were observed to stabilize).

[0127] The stability, appearance, and viscosity of each composition of Invention Example 1 and Comparative Examples 1-4 are summarized in Table 3.

[0128] Table 3 As can be seen from Table 3, the compositions according to the present invention are stable. Furthermore, it can be seen that the compositions according to the present invention have a viscosity higher than 1000 mPa·s and do not exhibit dripping problems.
