Description

[Technical Field]

[0001] The present invention relates to a film-forming composition containing at least two types of water-based acrylic emulsion bases. [Background technology]

[0002] Film-forming aqueous acrylic emulsion bases are so well known among those skilled in the art that they are included in the standards for raw materials for quasi-drugs and pharmaceutical additives in Japan. These acrylic emulsion bases consist of polymer particles dispersed in an aqueous solvent, such as water. When the aqueous solvent evaporates, the polymer particles fuse and deform together, forming a film. Specifically, the polymer particles in the emulsion fuse together at temperatures above the minimum film-forming temperature (MFT), and deform at temperatures above the glass transition temperature (Tg), forming a film.

[0003] Aqueous acrylic emulsion bases that form films by utilizing the above-described film formation are used, for example, in the field of cosmetics, and are incorporated into eyeliners, mascaras, and nail polishes. These cosmetics are required to be highly transparent, flexible, strong, and water-resistant. Patent Document 1 discloses an invention relating to an artificial nail coating composition that uses the acrylic emulsion base. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0011] 1. Film-forming composition according to the present invention The film-forming composition according to the present invention (hereinafter referred to as "the composition of the present invention") is characterized by containing the following component A together with 10 to 50 mass % of an acrylic emulsion base as component B: A) An acrylic emulsion base having a glass transition temperature (Tg) of 30°C or lower, a minimum film formation temperature (MFT) within the range of 15°C to 40°C, and a swelling ratio of 15% or lower when the formed film is immersed in water for 24 hours and allowed to swell, as calculated by the following formula (1):

[0012]

number

[0013] B) An acrylic emulsion base with a glass transition temperature (Tg) of 15°C or less and a minimum film formation temperature (MFT) of less than 20°C. The above-mentioned component B can be a base containing an acrylic emulsion base having a glass transition temperature (Tg) of less than 15°C and a minimum film formation temperature (MFT) in the range of 0°C to 25°C, and a plasticizer in the range of 1 to 10% by mass.

[0014] 1.1 About ingredient A The composition of the present invention contains Component A. Component A contains an acrylic emulsion base (film-forming agent) that has a glass transition temperature (Tg) of 30°C or lower, a minimum film-forming temperature (MFT) within the range of 15°C to 40°C, and a swelling ratio of 15% or lower, calculated from the following formula (1), when the film formed is immersed in water for 24 hours and allowed to swell. Such an acrylic emulsion base is usually in the form of an aqueous solution when used alone.

[0015]

number

[0016] As described above, the acrylic emulsion bases of Component A and Component B are prepared by dispersing polymer particles in an aqueous solvent such as water. When the aqueous solvent evaporates, the polymer particles fuse together and deform, forming a film. Therefore, Component A and Component B can form a film made of a polymer or the like on the body surface of a human or other subject. Furthermore, the water in which the polymer particles are dispersed is essentially the carrier solvent for the base. Therefore, the composition of the present invention contains water.

[0017] The glass transition temperature (Tg) of the acrylic emulsion base of component A is 30°C or lower, preferably in the range of 0°C to 25°C, and more preferably in the range of 5°C to 20°C. If the temperature is higher than 30°C, a film may not be formed on the surface of the human body, or even if a film is formed, it may develop obvious cracks, and the effects of the present invention may not be achieved. If the temperature is lower than -20°C, the adhesiveness of the film may be significantly increased. The glass transition temperature (Tg) is a physical property well known to those skilled in the art and can be determined by conventional methods. Specific examples include methods in which the temperature of a polymer sample is gradually increased or decreased while measuring changes in mechanical properties or endothermic and exothermic events (e.g., differential scanning calorimetry (DSC) and differential thermal analysis (DTA)), and mechanical spectroscopy (dynamic viscoelasticity measurement). Alternatively, Tg can be calculated using the Fox equation.

[0018] The minimum film-forming temperature (MFT) of the acrylic emulsion base for component A is usually within the range of 15°C to 40°C, preferably within the range of 20°C to 30°C, and more preferably within the range of 22°C to 25°C. If the temperature is higher than 40°C, a film may not form on the surface of the human body, or even if a film is formed, it may be subject to obvious cracking, and the effects of the present invention may not be achieved. Component A is not particularly limited as long as its MFT exceeds the MFT value of component B, and depending on the type of component B, it may have an MFT within the range of 0°C to 30°C, 5°C to 28°C, or 10°C to 25°C. The MFT is the lowest temperature at which a homogeneous, transparent film is formed, and can be determined by a minimum film-forming temperature measuring device in a conventional manner.

[0019] The film formed by the acrylic emulsion base related to Component A has a swelling ratio calculated from the above formula of 30% or less, preferably 20% or less, and more preferably 10% or less. If the swelling ratio is higher than 30%, the film formed on the surface of the human body may become cloudy when exposed to water, and may have poor water resistance.

[0020] 1.2 Component B The composition of the present invention contains Component B. Component B is an acrylic emulsion base having a glass transition temperature (Tg) of 20°C or lower and a minimum film formation temperature (MFT) of less than 20°C. Component B is an acrylic emulsion base having a glass transition temperature (Tg) of 20°C or lower and a minimum film formation temperature (MFT) in the range of 0°C to 25°C, and further containing a plasticizer, and the composition of the present invention may contain such a plasticizer in an amount of 1 to 10% by mass. Component B is usually an aqueous solution alone, and can function as an improver of film properties (e.g., film-forming ability at low temperatures) for films formed by a film-forming composition (e.g., component A).

[0021] The glass transition temperature (Tg) of the acrylic emulsion base related to component B is 20° C. or lower, preferably within the range of −20° C. to 20° C., more preferably within the range of −15° C. to 15° C., and even more preferably within the range of −12° C. to 12° C. If the temperature is lower than −20° C. or higher than 20° C., a film may not be formed on the surface of the human body, or even if a film is formed, obvious cracks may occur, and the effects of the present invention may not be achieved.

[0022] The minimum film-forming temperature (MFT) of the acrylic emulsion base for Component B is not particularly limited as long as it is lower than the MFT value of Component A, but is typically lower than 20°C. It is preferably lower than 17°C, and more preferably lower than 0°C. Component B can contain an appropriate amount of plasticizer. An acrylic emulsion base with an MFT of 20°C or higher, 17°C or higher, or 0°C or higher can be incorporated with a plasticizer to produce Component B with a temperature lower than 20°C, 17°C, or 0°C. For example, Component B may be an acrylic emulsion base with a glass transition temperature (Tg) of 20°C or lower (or within a range of −20°C to 20°C) and a minimum film-forming temperature (MFT) within a range of 0°C to 25°C, and a plasticizer added to the acrylic emulsion base. If the MFT is 20°C or higher, a film may not form on the surface of the human body, or even if a film is formed, it may be subject to obvious cracking, potentially preventing the effects of the present invention from being achieved.

[0023] The plasticizer in component B is not particularly limited as long as it can be used in the fields of cosmetics and pharmaceuticals and can lower the temperature of the MFT to below 0°C, but examples include polyhydric alcohols, esters, ester-based nonionic surfactants, and water-insoluble oils.

Examples of the fatty acids include stearic acid, oleic acid, isostearic acid, lauric acid, cetyl ether stearic acid, and stearyl ether stearic acid. Specific examples of the ester-based non-surfactant for Component B include polyethylene glycol monostearate (e.g., MYS-10V, MYS-25V, MYS-45MV, MYS-55MV (manufactured by Nikko Chemicals Co., Ltd.)), polyethylene glycol monooleate (e.g., MYO-10V (manufactured by Nikko Chemicals Co., Ltd.)), polyethylene glycol monoisostearate, polyethylene glycol monolaurate (e.g., MYL-10V (manufactured by Nikko Chemicals Co., Ltd.)), polyethylene glycol dilaurate, polyethylene glycol distearate, and polyethylene glycol dioleate.

[0032] The plasticizer may be used alone or in combination of any two or more kinds.

[0033] The content of the plasticizer varies depending on the desired plasticizer, the type and amount of the acrylic emulsion base for Components A and B, other components, etc., but is suitably in the range of 1 to 10 mass %, preferably in the range of 1.5 to 8 mass %, and more preferably in the range of 2 to 6 mass % in the composition of the present invention.
