Description

[Technical field]

[0001] The present invention relates to a cosmetic composition for cleansing the skin or a makeup remover composition. In particular, the present invention relates to a solid cleansing composition that contains little or substantially no water. [Background technology]

[0002] 2. Description of the Related Art Skin cleansing compositions have been known so far as they are capable of cleaning and removing aged stratum corneum, oily secretions, dirt, cosmetics, and the like from human skin.

[0003] Such compositions may generally exist as aqueous compositions, such as liquids, semi-solids (e.g., gels), etc. Conventional personal cleaning care compositions include makeup removers, facial cleansers, shaving agents, etc. They may also generally contain one or more ingredients (e.g., fragrances, preservatives, surfactants, etc.). In recent years, facial cleansers (including makeup removers) have become the subcategory with the highest penetration rate among facial skin care products in many markets. In addition to their cleansing action, such compositions may remove moisture from the skin during use, causing the skin to become too dry or rough, resulting in an unsatisfactory feel when used.

[0004] On the other hand, there are compositions that exist as solids that contain little or substantially no water, and when such compositions are applied to human skin, they can spread on the skin by external force and exert a cleansing effect. For example, cleansing agents generally called "soft solids" can give users a soft and refreshing feeling.

[0005] Patent Document 1 describes a solid anhydrous composition comprising hydrophobic aerogel particles, at least one wax having a melting point of 60° C. or higher, at least one hydrocarbon oil, and at least one nonionic surfactant. The composition has improved makeup removing power, cleaning power, and skin improving effect, is easy to carry, and can maintain good makeup removing effect. In addition, the composition has the hardness required to be compatible with the necessary equipment.

[0006] Patent Document 2 describes a solid anhydrous composition comprising a) at least one hydrophobic polymer selected from the group consisting of ester-terminated poly(ester-amide)s and mixtures thereof, b) at least one hydrocarbon-based oil, and c) at least one nonionic surfactant, which is used for cleansing keratinous materials and / or removing makeup.

[0007] Although some research has been conducted so far on the detergency, usability, makeup removing power and rinsability of anhydrous solid detergent compositions, such solid compositions contain components that are solid at room temperature (e.g., wax, etc.) and components that are liquid at room temperature (e.g., liquid oil components, etc.), and therefore have stability problems due to phase separation during production, transportation, storage and even use. This point has not yet been fully recognized or reported. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] CN106852117A [Patent Document 2] CN110062619A Summary of the Invention [Problem to be solved by the invention]

[0009] As described above, the detergency, usability, and rinsability of solid detergent compositions have been studied in the prior art. However, the inventors have conducted further research over a long period of time and found that stability problems may occur due to the presence of various components and oils that are solid at room temperature and are used in solid compositions to satisfy the above-mentioned usage characteristics.

[0010] For example, the solid composition may be subjected to external influences such as vibration (e.g., standing in a state different from the normal stable form) and temperature change during production, transportation, storage, and even use, which may cause phase separation between the solid components (including solid wax-like components) and liquid components such as oils, resulting in deterioration of appearance, usability, and even detergency. In particular, such a phenomenon becomes particularly noticeable after the solid composition has been subjected to a large temperature difference for a long time.

[0011] Therefore, the present invention provides a solid cleansing composition that contains little or substantially no water, and has good cleansing properties, a comfortable feel when used and easy to rinse off, while also having improved stability and being able to prevent phase separation due to the influence of external mechanical forces or temperature changes. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The configuration of the present invention will be described in detail below. The following description of the configuration of the present invention is based on representative embodiments and specific examples of the present invention, but the present invention is not limited to these embodiments and specific examples. In addition, the following description will be given.

[0019] In this specification, the term "may" means that the treatment may or may not be carried out.

[0020] As used herein, "optionally" or "optionally" refers to the use or non-use of an element such as a substance, ingredient, step, application condition, etc.

[0021] In this specification, "powder" and "particles" have the same physical meaning. "Solid powder particles" and "solid particles" have the same physical meaning.

[0022] In this specification, "room temperature" means an indoor ambient temperature of "25°C."

[0023] In this specification, all unit names are international standard unit names, and unless otherwise specified, "%" means percentage by weight or mass.

[0024] In this specification, "resin" and "rubber" have different meanings, and the two are distinguished by the presence or absence of "elasticity." Usually, the former does not have obvious elasticity, and the latter has obvious elasticity.

[0025] In the present invention, a "solid" composition is an expression that represents the form of a composition at 25° C. A "solid" is a composition having a hardness of 30 Nm when measured at 25° C. and atmospheric pressure (760 mmHg). -1The above means that the specific test method may be a method described in a patent document or prior art.

[0026] As used herein, "substantially free of water" means that in some embodiments of the invention, no water is added when the ingredients are mixed, meaning that any water that may be present in the composition comes only from trace amounts of moisture that are unavoidably contained in the raw materials.

[0027] As used herein, "some / preferred embodiments," "another (preferred) embodiment," "embodiment," and the like, mean that the particular elements (e.g., features, structures, properties, and / or characteristics) described in connection with the embodiment are included in at least one embodiment described herein and may or may not be present in other embodiments. However, these elements may be combined in any suitable manner in the various embodiments.

[0028] The present invention relates to a skin external preparation composition. In some embodiments, the skin cleansing composition contains little or substantially no water.

[0029] The skin external preparation composition of the present invention mainly contains solid particles (hereinafter also referred to as "solid powder particles") which are porous powders having open pores on the surface, a necessary wax component, an oil component, and a surfactant. In some preferred embodiments, the content of the water is 5% or less based on the total mass of the composition.

[0030] (solid powder particles) The skin external preparation composition of the present invention contains solid powder particles. The solid powder particles of the present invention are porous solid particles or porous solid powders having open pores on the surface.

[0031] In the present invention, the porous solid particles or porous solid powders are present mainly as primary particles in the skin external preparation composition. In some embodiments, the solid particles or powders present as primary particles account for 90% or more, preferably 95% or more, more preferably 98% or more of the total mass of all particles or powders.

[0032] In the present invention, the term "primary particles" refers to particles that exist in the form of a single particle, and is distinguished from "secondary particles" in terms of their state of existence. "Secondary particles" refer to aggregated particles formed when multiple solid particles with very small particle sizes gather together due to high surface energy, and examples of such particles include substances such as aerogel.

[0033] In some embodiments of the present invention, the primary particles of the present invention have an average primary particle size (D50) of 0.5 to 20 μm, preferably 3 to 18 μm, and more preferably 4 to 15 μm. If the average particle size of the primary particles is too small, the primary particles tend to aggregate to form secondary particles, which reduces the stability of the composition of the present invention. On the other hand, if the average particle size of the primary particles is too large, it may adversely affect the feel of use of the skin topical composition of the present invention, for example, causing excessive roughness or excessive friction.

[0034] The porous solid particles or powder of the present invention can be selected from silica particles having an open pore structure on the surface, surface-modified silica particles, organic polymer particles, or mixtures thereof. From the viewpoints of usability, thermal expansion / contraction resistance of the material, and safety, the porous solid particles or powder of the present invention are preferably silica particles having an open pore structure on the surface. In some embodiments, the porous solid particles or powder of the present invention may be hydrophobic particles or powders.

[0035] Furthermore, the surface-modified silica may be silica particles whose surface has been modified with a resin or rubber, such as silicone resin, silicone rubber, etc. The organic polymer particles may be selected from crosslinked or non-crosslinked organic polymer particles, such as particles made of (meth)acrylic resin, polyamide resin (nylon powder), polyethylene, polystyrene, copolymer resin of styrene and (meth)acrylic acid, benzoguanamine resin, polytetrafluoroethylene, cellulose, silicone resin, silicone rubber, etc., or composite particles made of two or more of these substances (for example, core-shell).

[0036] The porous solid particles or powder of the present invention have an open pore structure on the surface. The term "open pore" refers to holes that exist on the surface of the particles or powder and communicate with the outside.

[0037] In some embodiments, the average pore diameter of the pores is 7.5 nm or more, or 8 nm or more, or 10 nm or more, or 12 nm or more. Regarding the upper limit of the average pore diameter of the pores, in some embodiments, the average pore diameter of the pores is 50 nm or less, or 30 nm or less, or 20 nm or less. Furthermore, in some preferred embodiments of the present invention, the average pore diameter of the pores is preferably 7.5 to 15 nm.

[0038] The average pore size of the surface pores in the present invention can be measured by a known method. Usually, standard gas adsorption analysis tests can be performed by nitrogen adsorption at liquid nitrogen temperature, and the resulting data can be processed by the Barrett-Joyner-Halenda method (abbreviated as BJH method) to obtain the final measured value.

[0039] In some embodiments, the specific surface area of ​​the porous solid particles of the present invention is 400 m 2 / g or less, preferably 80 to 400m 2 / g or 100~400m 2 / g, and more preferably 200 to 350 m 2 / g. The specific surface area of ​​the present invention can be determined by the BET (Brunauer-Emmett-Teller) nitrogen adsorption method described in the Journal of the American Chemical Society (vol. 60, p. 309, February 1938) and the international standard ISO 5794 / 1 (Appendix D). The BET specific surface area corresponds to the total specific surface area of ​​the particles under test.

[0040] The oil absorption of the porous solid particles of the present invention is not particularly limited, but is related to the specific surface area and particle size. However, from the viewpoint of the stability of the skin external preparation composition of the present invention, the porous solid particles of the present invention have an oil absorption of 300% or less, preferably 50-250% or 100-250%. The oil absorption can be measured by known techniques, such as the wet point method or the method for measuring the oil absorption of powders described in the standard NF T 30-022.

[0041] In the present invention, it is believed that the porous solid particles or solid powder having the above-mentioned configuration will be useful in preventing the problem of decreased stability due to phase separation when mixed with other components to be incorporated in the topical skin composition of the present invention.

[0042] As a result of the study of the present invention, it is presumed that the above-mentioned effect is caused by the following mechanism. In the skin external preparation composition of the present invention, a wax component is mainly used as a solid component at room temperature, and is mixed with an oily component, solid particles, a surfactant, etc. During mixing, the oily component penetrates into the open pores on the surface of the solid particles, that is, the open pore structure on the surface exhibits the effect of fixing the oily component that enters. As a result, even if the obtained skin external preparation composition is subjected to external mechanical force stimulation (such as vibration during transportation or use) or temperature change stimulation (such as temperature change due to storage conditions or regional or seasonal differences), the oily component does not separate and precipitate from the solid phase of the skin external preparation composition, and the stability of the entire skin external preparation composition of the present invention is improved, and the original feeling of use and cleaning power are maintained. In addition, this fixing effect is well exhibited even when the content of porous solid particles is 10% or less.

[0085] [Table 2]

[0086] <Manufacturing method> [Material preparation] Material A: Put the wax into some hydrocarbon oil and heat it to 90±2℃ until it is completely melted. Material B: Mix the solid particles and the remaining oil, and stir vigorously until the particles are fully dispersed. Then add material A, keep the temperature at 85±2℃, add other raw materials in order, filter and discharge after mixing, and store.

[0087] [Filling material] The material is placed in a kettle and heated to 82±2℃, and filled once the material is fully melted. After filling, the semi-finished product is cooled to obtain a cylindrical cooled product, which is then packed into a box and stored at room temperature.

[0088] <Test Method> [Usability evaluation] The skin (face) was cleansed using the solids obtained in the following Examples and Comparative Examples, and after rinsing with water, the presence or absence of a sticky feeling was tested (average data of 20 people).

[0089] [Stability evaluation] The test specimens were placed in an oven on their side, and the oven temperature was set to 5 to 45°C, with two cycles per day, with temperatures at 5°C and 45°C maintained for two hours each. As shown in the temperature control curve in Figure 1, 28 cycles of temperature change treatment were carried out over a total of 14 days, and it was observed whether oil had seeped out onto the surface of the test specimens. The stability of the system was evaluated by carrying out the temperature change treatment with the cylinder lying on its side (instead of standing upright, see Figure 2) to simulate temperature changes under abnormal storage conditions that may occur during transportation and storage.
