Description

Technical Field

[0001] The present invention relates to a composition, preferably a cosmetic composition, more preferably a cosmetic composition for keratinous substances such as skin and lips, containing at least two different waxes.

Background Art

[0002] Cosmetics may contain a structured, i.e., gelled and / or stiffened, fatty phase as in self-supporting solid compositions such as deodorants, lip balms, lipsticks, concealers, and eyeshadows. This structuring can be achieved by utilizing waxes in the fatty phase.

[0003] Such conventional self-supporting solid compositions, typically in stick form, contain a relatively high concentration of wax and an extremely low concentration of water to maintain a robust self-supporting stick shape with good stability. Therefore, conventional self-supporting solid compositions tend to be hard, give a heavy texture upon application, and are difficult to provide sufficient adhesion onto keratinous substances such as skin and lips.

[0228] In this specification, the term "solid" means a state that is not fluid at atmospheric pressure (101325 Pa) and room temperature (25°C). Solid compositions have high viscosity and can maintain their form during storage. In contrast to "fluid" compositions, solid compositions do not flow due to their own weight. For example, a solid composition remains unfluid after one hour at room temperature and atmospheric pressure due to its own weight.

[0229] The composition according to the present invention preferably has a hardness of less than 10 g / mm, preferably less than 9 g / mm, and more preferably less than 8 g / mm.

[0230] The hardness of the composition can be evaluated using the "cheese wire" method. This method requires cutting a stick-shaped portion of the composition with a diameter of 8 mm using a metal wire at a speed of 0.16 to 0.19 cm / second at 20°C, and measuring its hardness using a force measuring instrument such as Ametek's Chatillon®. The hardness obtained by this method can be expressed in grams / mm as the maximum shear force required to cut the stick under the above conditions.

[0231] [Cosmetic Use and Methods] The composition according to the present invention may be a cosmetic composition, preferably a skincare or makeup composition, more preferably a skincare stick, a concealer stick, or a lipstick.

[0232] The cosmetic composition according to the present invention can be used for cosmetic treatment, preferably care or makeup, of keratinous substances on the surface of the skin and mucous membranes, such as the lips.

[0233] Therefore, the present invention also relates to a cosmetic method for keratinous substances such as skin and lips, comprising the step of applying a composition according to the present invention onto a keratinous substance.

[0234] For example, the composition according to the present invention can be used for a cosmetic method for caring for or applying makeup to keratinous substances such as skin and mucous membrane surfaces (e.g., lips), the method comprising the step of applying the composition according to the present invention onto the keratinous substance.

[0235] The compositions according to the present invention can provide cosmetic effects such as coloring (e.g., makeup) and / or care (e.g., brightening, anti-aging, and moisturizing) of keratinous substances such as skin and lips.

[0238] The present invention will be described in more detail by reference to examples. However, these examples should not be construed as limiting the scope of the present invention. The following examples are presented as non-limiting illustrations in the art of the present invention.

[0239] (Examples 1-5 and Comparative Examples 1-7) [Preparation] Each of the compositions from Examples 1-5 and Comparative Examples 1-7 was prepared by mixing the components shown in Tables 1-2.

[0240] In detail, the components of Phase A in Tables 1-2 were heated to 85-90°C to ensure complete melting, mixed, and cooled to 80°C. The components of Phase B in Tables 1-2 were heated to 75-80°C and mixed to ensure complete melting. The mixture of Phase B components was slowly added to the mixture of Phase A components and homogenized at 7,000 rpm for 5 minutes at 75-80°C to obtain the compositions of Examples 1-5 and Comparative Examples 1-7 in the form of W / O emulsions.

[0241] All numerical values ​​for the amount of ingredients in Tables 1 and 2 are based on the "mass %" of the raw materials.

[0242] [Table 2A]

[0243] [Table 2B]

[0244] [Table 3A]

[0245] [Table 3B]

[0246] [evaluation] The compositions produced by Examples 1-5 and Comparative Examples 1-4, 6, and 7 were evaluated as follows.

[0247] The composition according to Comparative Example 5 underwent phase separation after its preparation, and therefore, the composition according to Comparative Example 5 could not be evaluated.

[0248] (Formation of self-supporting sticks) The compositions from Examples 1-5 and Comparative Examples 1-4, 6, and 7 were each heated to 75°C. The compositions from Examples 1-5 and Comparative Examples 1-4 and 7 were each poured into the cavity of a cylinder mold for sticks that had been heated to 45°C and then cooled to -15 to -20°C for 20 minutes. The composition from Comparative Example 6 could not be poured into the cavity of the mold for sticks because its viscosity was too high.

[0249] Next, the mold was heated to room temperature (25°C), and each of the compositions from Examples 1-5 and Comparative Examples 1-4 and 7 was released or extruded from the mold cavity. The formation of self-standing sticks was then evaluated according to the following criteria. Yes: A self-supporting stick was formed. None: No self-supporting stick was formed.

[0250] The results are shown in the row labeled "Formation of Self-Supporting Sticks" in Tables 1 and 2.

[0251] (hardness) The hardness of each composition from Examples 1-5 and Comparative Examples 3, 4, and 7 was measured at 20°C using a tester (Chatillon® DFGHS2 manufactured by Ametek). Here, the compositions were in the form of cylinders with a diameter of 8 mm and were maintained at 20°C for a period of more than one day before cutting. Hardness was determined as the maximum shear force (g) / mm when the composition was cut longitudinally at a point 1 cm from the end of the cylinder using a metal wire at a speed of 0.16-0.19 cm / sec at 20°C.

[0252] The results are shown in the "Hardness" row in Tables 1 and 2.

[0253] (Soft texture / melting sensation / adhesion) The compositions from Examples 1-5 and Comparative Examples 3, 4, and 7 were applied to the skin of four sensory panelists. The softness of the feel after application, the sensation of dissolving during application, and the degree of appropriate adhesion after application were evaluated on a scale of 1 to 5. The scores were averaged and classified according to the following criteria. Excellent: 4-5 Good: Less than 3-4 Defective: 2-3 Extremely poor: Less than 1-2

[0254] The results are shown in the rows for "Soft texture," "Melting sensation," and "Appropriate adhesion" in Tables 1 and 2.

[0255] (summary) The compositions according to Examples 1 to 5, which correspond to the present invention, were able to form self-standing solid sticks and were soft enough to provide a comfortable feeling such as sufficient adhesion and a melting sensation, as well as a soft touch.

[0256] The composition according to Comparative Example 1, which did not contain wax, was in liquid form (at 25°C) and therefore not in the form of a self-standing solid stick.

[0257] The composition according to Comparative Example 2, which contained only one type of wax, was in the form of a cream (at 25°C) and therefore not in the form of a self-standing solid stick.

[0258] The composition according to Comparative Example 5, which did not contain hydrocarbon oil, was in a solid form with phase separation and was therefore an unstable composition for the preparation of sticks.

[0259] The composition according to Comparative Example 6, which did not contain polyglyceryl fatty acid esters, had a very high viscosity and could not be poured into the cavity of the mold for the stick.

[0260] The compositions of Comparative Examples 1, 2, 5, and 6 failed to form self-standing solid sticks.

[0261] The compositions from Comparative Example 3 (containing only one type of wax), Comparative Example 4 (containing only one type of wax), and Comparative Example 7 (not containing a sufficient amount of water) were able to form self-standing solid sticks. However, these failed to provide a suitable sensory texture with sufficient adhesion, a comfortable feeling such as a melting sensation, and a soft touch.
