Description

[Technical field]

[0001] The present invention relates to a two-layer type lotion. [Background technology]

[0002] To finish off your makeup, it is common to use face powder with a low oil content. Face powder absorbs sebum and sweat, which helps foundation last longer and prevents makeup from coming off. It also has the aesthetic effect of diffusing light to make skin look more three-dimensional. Creased eyeshadow and uneven blush can also be solved by carefully applying face powder.

[0003] Conventionally, face powder is basically applied with a puff and excess powder is removed with a face brush, but to save this time, a spray-type finishing makeup cosmetic has been proposed in which a powder is mixed into an aqueous volatile solvent and sprayed onto the face after the makeup cosmetic has been applied (Patent Document 1). However, with a finishing cosmetic that contains only a powder, it is difficult to improve makeup staying power and it is also impossible to prevent secondary adhesion.

[0004] Similarly, finishing cosmetics (called finishing mists) that are sprayed onto the skin after makeup are also commercially available, and are touted to fix makeup and prolong the beauty of the finish by blending fragrances (rose extract) and moisturizing ingredients (aloe extract), etc. However, considering the ingredients, it is presumed that a high inhibitory effect on makeup breakdown and secondary adhesion cannot be expected.

[0005] On the other hand, it is also known that a cosmetic material (also called an overcoat) in which a specific resin selected from fluororesin, silicone resin, aromatic hydrocarbon resin, terpene resin, polybutene, polyisoprene, alkyd resin, and PVP-modified polymer is dissolved in a volatile oil is applied to the makeup surface, and the surface is covered with the resin film to prevent color dulling, makeup breakdown, and secondary adhesion (Patent Document 2). However, the conventional ingredients in these cosmetic materials The film formed from the resin is hard and crispy to the touch and does not move well with the skin. However, the effect was not satisfactory in terms of texture or effectiveness.

[0006] A finishing cosmetic composition containing fine cellulose fibers and a polymer capable of forming a film in an aqueous medium has also been disclosed (Patent Document 3). However, the redispersibility of the powder and the cosmetic durability were not satisfactory. [Prior art documents] [Patent documents]

[0010] The two-layer type lotion of the present invention is resistant to rubbing caused by masks and has excellent makeup lasting properties. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described.

[0012] [Pullulan] Pullulan, which is incorporated in the two-layer type lotion of the present invention, is a water-soluble polymer having a structure in which maltotriose, which is made up of three glucose molecules linked by α1-44 bonds, is linked by α1-6 bonds. Commercially available pullulan products include "Pullulan for cosmetics" and "Pullulan as food additive" (both manufactured by Hayashibara Biochemical Laboratories, Inc.).

[0013] The content of pullulan in the two-layer type lotion of the present invention (100% by mass) is preferably 0.001% by mass or more, more preferably 0.003% by mass or more, preferably 1.0% by mass or less, more preferably 0.5% by mass or less, and even more preferably 0.2% by mass or less, from the viewpoint of makeup retention effect. If it is less than 0.001% by mass, the makeup retention effect may not be obtained. If it is blended in an amount exceeding 1.0% by mass, the usage sensation may be sticky.

[0014] [Spherical cellulose] The spherical cellulose blended in the two-layer type lotion of the present invention is spherical crystalline cellulose, and preferably has an average particle size measured by a microscopic method of 1 to 50 μm. Commercially available products include CELLULOBEADS D-10, CELLULOBEADS D-5, CELLULOBEADS USF (all manufactured by Daito Chemical Industry Co., Ltd.), GE-800 (manufactured by Toshoku Pigment Co., Ltd.), TEGO Feel C 10 (manufactured by Evonic Operations Co., Ltd.), Nature Soft 800 (manufactured by Micro Powders Co., Ltd.), etc.

[0015] The content of spherical cellulose in the two-layered lotion of the present invention (100% by mass) is preferably 0.01% by mass or more, more preferably 0.05% by mass or more, and preferably 5.0% by mass or less, more preferably 2.0% by mass or less, from the viewpoint of cosmetic durability. If it is less than 0.01% by mass, the feeling of use may be sticky. If it is blended in an amount exceeding 1.0% by mass, good redispersibility may not be obtained.

[0016] The two-layer type lotion of the present invention is shaken at the time of use to disperse the powder evenly, and when left to stand after use, it separates into two layers, a powder layer and a water layer.

[0017] The two-layer type lotion of the present invention is preferably used as a finishing cosmetic to be applied on make-up-applied skin.

[0018] The method of application of the two-layer type lotion of the present invention is not particularly limited. For example, it may be applied by an applicator such as the hand or a puff, or it may be sprayed as a spray, aerosol or mist, but it is preferably used in the type that is sprayed as a mist.

[0019] Since the two-layer type lotion of the present invention is sprayed in the form of a mist, it is preferable to blend one or more types selected from ethylhexylglycerin and tetra-fatty acid polyoxyethylene sorbitol.

[0020] Ethylhexylglycerin is a compound in which ethylhexanol is ether-bonded to glycerin, and is not particularly limited as long as it is a component that is usually blended into cosmetics.

[0021] Commercially available ethylhexylglycerins include BEG-800 (manufactured by B&B), CleanBio-EHG (manufactured by Kolon Life Sciences), dermosoft EHG (manufactured by Evonic Dr. Straetmans), Lexgard E (manufactured by Inolex Chemical), Microcare Emollient EHG (manufactured by Thor Japan), sensiva SC 50 JP (manufactured by Schule & Mayr), Sharomix E-50 (manufactured by Sharon Laboratories), Grimoist (manufactured by NOF Corp.), ADEKA NOL NHG (manufactured by ADEKA), and 1sasKINE 50 (manufactured by SACHEM).

[0022] Tetra fatty acid polyoxyethylene sorbitol can be obtained by esterification of fatty acid with polyoxyethylene sorbitol obtained by addition reaction of ethylene oxide to sorbitol.

[0023] The constituent fatty acid residue is, for example, a fatty acid residue having 6 to 18 carbon atoms. Examples of such fatty acids include saturated fatty acids such as caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, and isostearic acid, and unsaturated fatty acids such as oleic acid, linoleic acid, and linolenic acid. In addition, fatty acid residues derived from mixed fatty acids can also be used, and examples thereof include fatty acid residues such as caprylic acid / capric acid, coconut oil fatty acid, and palm oil fatty acid. Among these fatty acids, oleic acid and / or isostearic acid are preferred.

[0024] The average number of moles of oxyethylene groups added per molecule of sorbitol is preferably 3 to 80, particularly preferably 6 to 60, and further preferably 20 to 60. If the average number of moles added is too small, the cosmetic composition may sting the eyes, whereas if the average number of moles added is too large, the cosmetic composition may lose its staying power.

[0025] Examples of tetra fatty acid polyoxyethylene sorbitols are, as cosmetic names, sorbeth-30 tetraisostearate, sorbeth-40 tetraisostearate, sorbeth-50 tetraisostearate, sorbeth-30 tetraoleate, sorbeth-40 tetraoleate, and sorbeth-60 tetraoleate.

[0026] Commercially available tetra fatty acid polyoxyethylene sorbitols can also be used. For example, tetraisostearate sorbeth-30 includes UNIOX ST-30IS (manufactured by NOF Corp.), tetraoleate sorbeth-30 includes NIKKOL GO-430NV (manufactured by Nikko Chemicals Corp.) and UNIOX ST-30E (manufactured by NOF Corp.), tetraoleate sorbeth-40 includes EMALEX PESO-440 (manufactured by Nippon Emulsion Co., Ltd.), NIKKOL GO-440V (manufactured by Nikko Chemicals Corp.) and UNIOX ST-40E (manufactured by NOF Corp.), and tetraoleate sorbeth-60 includes NIKKOL GO-460V (manufactured by Nikko Chemicals Corp.) and UNIOX ST-60E (manufactured by NOF Corp.).

[0034] [Evaluation of resistance to chafing caused by masks] To evaluate resistance to rubbing caused by masks, the following procedure was used with reference to the August 2020 issue of the magazine LDK (publisher Shinyusha). 0.01 g of a commercially available foundation was applied to a 1.5 x 1.5 cm section of black artificial leather and then allowed to dry for 10 minutes. The examples and comparative examples of the present invention were filled into a spray bottle, and one push was applied from a position 20 cm away from the artificial leather, followed by drying for 10 minutes. Next, purified water and oleic acid, each filled in a spray container, were sprayed in the same manner. A nonwoven mask was placed on top of the artificial leather, the top and bottom were clamped with magnets, and the mask and artificial leather were then pulled out. (Visual evaluation) The foundation that had transferred to the mask was visually observed and evaluated according to the following criteria. 〇: Strong makeup retention △: Has some makeup retention power ×: No makeup retention (survival rate) The area ratio of FD remaining in the skin grooves of the evaluated artificial leather was calculated using a microscope and evaluated according to the following criteria. 〇: 50% or more remaining △:45% or more remaining ×: Less than 45% remaining

[0035] [Mist state] The examples and comparative examples of the present invention were filled into a spray bottle, and the fineness of the mist sprayed and the absence of dripping were evaluated according to the following criteria. 〇: Produces a fine mist beautifully △: The mist is a little rough and drips a little. ×: The mist is coarse and drips.

[0036] [Table 1]

[0037] As shown in Table 1, the incorporation of pullulan has been shown to improve resistance to rubbing caused by masks and make-up durability.

[0038] [Table 2]

[0039] As shown in Table 2, Comparative Example 13, which contained fibrous cellulose, was not good in terms of resistance to rubbing caused by the mask and the state of the mist. Moreover, Examples 3 to 6, which contained ethylhexylglycerin and tetra fatty acid polyoxyethylene sorbitol, had good mist states.
