• the high viscosity is preferably 500 mm 2 /s or less, more preferably 400 mm 2 /s or less as a suitable upper limit of the kinetic viscosity at 25°C, and preferably 300 mm 2 /s or more as a suitable lower limit.
• the content of the high-viscosity non-volatile oil is preferably 10% or less, more preferably 5% or less, even more preferably 3% or less, and more preferably 1% or less of the total mass of the composition (preferably the cosmetic).
• the content of the high-viscosity non-volatile oil is preferably not more than 30% by mass in the total amount of non-volatile oils (the low-viscosity non-volatile oil and non-volatile oils with a different viscosity), and more preferably is not substantially contained (1 or 0.5% by mass or more).
• the composition further contains water.
• this embodiment can also provide a multi-layered makeup protection cosmetic composition containing the above-mentioned components (A) to (D) and water. This can provide a better makeup protection effect and a finer mist.
• the water is not particularly limited as long as it is one that can be normally used in cosmetics or topical skin preparations, but in addition to purified water, ion-exchanged water, seawater, deep ocean water, and steam-distilled water from plants can also be used, and one or more types selected from these can be used.
• the lower alcohol is preferably one having 1 to 4 carbon atoms, and 1,3-butylene glycol is preferred.
• the content of the aqueous component in the present embodiment is not particularly limited, but a suitable lower limit of the total mass of the composition (preferably the cosmetic) is preferably 1% or more, more preferably 3% or more, and even more preferably 5% or more, and a suitable upper limit of the total mass of the composition (preferably the cosmetic) is preferably 30% or less, more preferably 25% or less, even more preferably 20% or less, and even more preferably 15% or less.
• the total composition does not contain 0.25% or more of emulsifier, preferably 0.1% or more, more preferably 0.05% or more.
• the components used in the present embodiment may be filled in a plurality of containers, such as a container for an aqueous layer, a container for an oily layer, and a container for powder, to form a multi-liquid combination product, such as a two-liquid type or a three-liquid type.
• the present embodiment may also be combined with tools such as a container and an application tool.
• the combination may be a set or a kit.
• the user can mix the aqueous layer component, the oily layer component, the powder component, etc. in a desired ratio and then spray the product when using the product.
• this embodiment can be used in an aerosol form using a propellant, but from the standpoint of ease of use, such as being easy to spray on the face, it is preferable to use a spray container that does not use a propellant.
• this embodiment by combining the components (A) to (D) in this embodiment, a film having high water resistance and sebum resistance due to the oleophilic resin can be formed on the applied makeup, and it is also possible to have a makeup protection effect with excellent long-lasting properties. Furthermore, this embodiment has the advantage that it can be sprayed onto the entire face in fine mist-like particles, and a film having high water resistance and water repellency can be formed on the entire face.
• Non-volatile oil The oils described below as [Low viscosity non-volatile oil] and [High viscosity non-volatile oil] used in Tables 1 to 3 were obtained as non-volatile oils that were liquid at 25° C. and normal pressure.
• compositions of the present technology (Examples 1 to 28, Reference Example 1) produce a fine mist that can be sprayed softly over the entire face, so they do not damage applied makeup, and have the advantage that even a typical user can easily form an appropriate, even makeup film over the entire face.
• the compositions of the present technology have the advantage of being highly sebum-resistant, as makeup does not come off even after application for as long as 8 hours, and are considered to have a high skin protection effect.
• these compositions preferably contain a volatile oil, and when they contain water, the water content is preferably in the range of approximately 50 to 85% by mass, and it is considered possible to adjust it to 1 to 95% by mass.
• the protective composition of the present technology contains component (A) an oleophilic resin (film-forming resin), component (B) ethanol, component (C) a metal salt, and component (D) a low-viscosity non-volatile oil, and is therefore excellent in terms of the fineness of the mist when sprayed, the makeup protection effect, the speed of film formation, the non-sticky feel when used, and the anti-clogging effect.
• the preferred mass ratio of (B)/(A) used is in the range of 1 to 200, with the more preferred range being 2 to 100.
• the preferred mass ratio of (C)/(A) used is in the range of 0.1 to 20, with the more preferred range being 0.2 to 10.
• the preferred mass ratio of (A)/(D) used is in the range of 0.01 to 6, with the more preferred range being 0.1 to 3.
• the protective composition of the present technology contains component (A) an oleophilic resin (film-forming resin), component (B) ethanol, component (C) a metal salt, and component (D) a low-viscosity non-volatile oil, and is therefore excellent in terms of the fineness of the mist when sprayed, the makeup protection effect, the non-sticky feel when used, and the effect of preventing clogging of the spray nozzle. Furthermore, by further containing water and/or a volatile oil, it is possible to obtain a composition that is extremely excellent in terms of the fineness of the mist when sprayed, the makeup protection effect, the non-sticky feel when used, and the effect of preventing clogging of the spray nozzle.
• Formulation Example 1 is a multi-layered composition containing ingredients (A) to (D) and water, and was excellent in all respects: fineness of mist when sprayed, makeup protection effect, speed of film formation, non-sticky feel when used, and anti-clogging effect.
• the container containing the composition was shaken to mix and spray.
• the composition was a multi-layered makeup protection agent separated into two layers, an oil layer on top and a water layer on the bottom.
• Formulation Example 2 is a multi-layered composition containing ingredients (A) to (D) and water, and was excellent in all respects: fineness of mist when sprayed, makeup protection effect, speed of film formation, non-sticky feel when used, and anti-clogging effect.
• the container containing the composition was shaken to mix and spray.
• the composition was left to stand, there was an oil layer on top, a water layer below, and a powder layer at the bottom of the lower layer, making it a multi-layered makeup protection agent separated into three layers.
• Formulation Example 3 is a multi-layered composition containing ingredients (A) to (D) and water, and was good in all respects: fineness of mist when sprayed, makeup protection effect, speed of film formation, non-sticky feel when used, and anti-clogging effect.
• the container containing the composition was shaken to mix and spray.
• the composition was a multi-layered makeup protection agent that separated into two layers, an oil layer on top and a water layer on the bottom. Even when the multi-layered composition was filled into the non-aerosol container used in Example 1 and used, it was good in all respects: fineness of mist when sprayed, makeup protection effect (skin protection effect), smooth feel when used, anti-gloss effect, and layer separation.
