Description

The present invention relates to an oil-in-water emulsion cosmetic.

Oil-in-water emulsion cosmetics are moist and refreshing to use, and therefore various sunscreen cosmetics and makeup cosmetics are being investigated for use therein.
For example, Patent Document 1 describes that an oil-in-water emulsion sunscreen containing a (meth)acrylic silicone graft copolymer, a water-soluble polymer, and an ultraviolet protection agent has excellent makeup wear, is not burdensome on the skin, is non-sticky, and has excellent cleansing properties and stability over time.

JP 2014-73973 A

However, the oil-in-water emulsion cosmetic of Patent Document 1 had problems in that the cosmetic film after application had an unnatural gloss and was perceived as shiny due to the oil. In addition, the moist feeling was insufficient, and the covering power for blemishes was poor.

The inventors have discovered that by combining a specific non-volatile silicone oil with a polyacrylamide compound and a hydrophobically treated color pigment, it is possible to obtain an oil-in-water emulsion cosmetic that solves the above problems.

The present invention comprises the following components (A), (B) and (C):
(A) 0.1 to 30% by mass of a non-volatile silicone oil that is incompatible with squalane,
(B) 0.1 to 5% by mass of a polyacrylamide compound,
(C) Hydrophobically treated color pigment: 0.01 to 30% by mass
The present invention relates to an oil-in-water emulsion cosmetic comprising the above-mentioned compound.

The oil-in-water emulsion cosmetic of the present invention provides a matte finish after application, reduces glare, and also provides a moist feel and excellent coverage for blemishes.

The component (A) used in the present invention is a non-volatile silicone oil that is incompatible with squalane.
The term "non-volatile" refers to an oil agent that has a mass loss of 1% or less after 1 g of the oil agent is spread on a glass petri dish having a diameter of 48 mm and left for 24 hours at normal pressure at 25° C. The silicone oil may be a linear silicone oil such as dimethylpolysiloxane, or a modified silicone having a substituent such as phenyl-modified silicone or methylhydrogenpolysiloxane.
In addition, the term "not compatible with squalane" means that when silicone oil and squalane are mixed in a mass ratio of 1:1, and stirred and mixed by hand with a stroke frequency of 120 times/min and a stroke width of 30 cm for 30 seconds, then further stirred with a vortex mixer for 30 seconds, and then allowed to stand for 1 minute, and the state is observed, and the mixture becomes cloudy. Such silicone oil separates into two layers over time.

Component (A) preferably contains at least dimethylpolysiloxane, which is incompatible with squalane and therefore improves the matte finish after application of the cosmetic.

Furthermore, from the viewpoint of improving the matte finish after application of the cosmetic preparation by being incompatible with squalane, component (A) preferably has a viscosity at 25°C of 30 to 100,000 mPa·s, more preferably 50 to 10,000 mPa·s, even more preferably 100 to 5,000 mPa·s, and even more preferably 700 to 2,000 mPa·s.
The viscosity here is measured at 25° C. using a B-type viscometer (TVB-10 model, manufactured by Toki Sangyo Co., Ltd., measurement conditions: rotors TM1 to TM4, 6 rpm, 1 minute). Viscosities of 30 to 1000 mPa·s are measured using TM1, 1000 to 5000 mPa·s using TM2, 5000 to 20000 mPa·s using TM3, and 20000 to 100000 mPa·s using TM4.

Component (A) may be used alone or in combination with other components. From the viewpoints of improving the matte finish after application of the cosmetic composition by being incompatible with squalane, reducing glare, and improving the moist feeling and covering power for blemishes, the content is 0.05 to 30% by mass, preferably 0.1 to 30% by mass, more preferably 0.5 to 20% by mass, and even more preferably 3 to 15% by mass, of the total composition.
The reason why the oil-in-water emulsion cosmetic of the present invention improves the matte finish after application of the cosmetic is presumably because component (A) is not compatible with squalane, and therefore component (C) dispersed in component (A) is less likely to mix with sebum secreted from the skin, resulting in a uniform dispersion in component (A). In addition, the cosmetic of the present invention contains component (B), which improves the dispersibility of component (C) in component (A), and is therefore thought to further improve the matte finish.
