Description

Composition for cleansing the scalp and method for preparing the same

[0001] The present invention relates to a scalp cleansing composition and a method for manufacturing the same, according to embodiments of the present invention.

[0002]

[0003] The scalp is composed of the epidermis, dermis, and subcutaneous tissue. The stratum corneum of the scalp undergoes turnover, with new stratum corneum cells being replaced approximately every month. In a healthy scalp, small keratinocytes are shed during stratum corneum turnover and replaced with new keratinocytes. However, if turnover deviates from the normal state and there are excessive keratinocytes, they may clump together and fall off in visible clumps, which is called dandruff. This dandruff can be caused by increased sebum secretion, increased microbial proliferation and activity, and abnormal keratinization due to scalp metabolism.

[0004] Additionally, changes in temperature and humidity, exposure to sunlight, and pollutants like fine dust can irritate and contaminate the scalp during daily life. Furthermore, stress and nutritional deficiencies can also worsen scalp conditions. To address these potential scalp problems, various scalp care products are used to cleanse and purify the scalp and hair.

[0005] Current scalp care products on the market, such as scalp scaling or scalp exfoliation products, either apply to hair before shampooing and then rinse with water, or apply to the scalp, allow to absorb, and then physically exfoliate with finger massage (e.g., a physical scaling (scrubbing) function). These products require the hassle of additional shampoo or conditioner after use, and can cause secondary irritation or damage due to product residue.

[0006] Therefore, there is a need for the development of a scalp and hair cosmetic composition having scalp scaling and cleansing functions that can be easily removed during the rinsing process, can be conveniently used with the functions of a shampoo or conditioner, and can wash away residues well or minimize damage to the scalp and hair caused by residues.

[0145] (1) Bubble generation power

[0146] In order to compare the foaming power (the degree to which bubbles are generated) of each of the examples and comparative examples, 250 ml of each 5% aqueous solution was taken and bubbles were generated (3 sets) at 800 rpm for 20 seconds using the rotor of a foam tester (SITA foam tester R-2000, manufacturer: SITA Messtechnik GmbH). After stopping the rotor, the volume (mL) of the generated bubbles was measured. The results are shown in Table 1.

[0147]

[0148] (2) Hair residue

[0149] To measure the amount of amphoteric surfactants of the examples and comparative examples remaining on the hair, a Rubine Dye Test was conducted.

[0150]

[0151] 1 g of the compositions of Examples and Comparative Examples were rubbed on a wool swatch with 10 g of 33°C water for 1 minute, and then washed with running water for 30 seconds. After washing, the wool swatch was immersed in a 0.5% Rubin dye solution for 3 minutes, and the degree of color development was measured using a colorimeter to obtain a colorimeter contrast value (ㅿa), which indicates the degree of red color development. As a result, the amount of hair residue could be confirmed as described in Table 2.

[0152]

[0153] Example 1 Example 2 Example 3 Example 4 Comparative Example 1 Comparative Example 2 Comparative Example 3 Foam generation power (mL) 536539593529420450608 Hair residual amount (ㅿa) 10.2589.65211.24412.54630.25432.65235.652

[0154] Rubin dye is an anionic pigment that ionically bonds with amphoteric surfactant complexes adsorbed to the scalp and hair. Therefore, by analyzing the degree of Rubin dye dyeing with a colorimeter, the amount of surfactant remaining on the scalp and hair can be compared. If the degree of Rubin dye dyeing is high, the ㅿa value, which indicates the degree of redness in the colorimeter, will increase, indicating that there is a lot of surfactant residue that can damage the hair.

[0155] In Table 2, it can be confirmed that the products of Examples 1 to 4 of the present invention have excellent foaming power and a small amount of residue on the hair / scalp after washing by using two or three types of amphoteric surfactants. On the other hand, it can be confirmed that Comparative Examples 1 and 2 have weak foaming power and a large amount of residue, and Comparative Example 3 has increased foaming power but a large amount of residue.

[0156] The present invention can provide a scalp cleansing composition that reduces damage and irritation to the scalp / hair and has high cleansing power.

[0157]
