Description
Technical Field
The present invention relates to an oil-in-water type emulsion cosmetic.
Background
Due to intrinsic factors such as aging and stress or extrinsic factors such as ultraviolet rays or air dryness, skin is wrinkled or slacked, and pigmentation such as spots or freckles is generated. Among them, morphological changes such as wrinkles and sagging and visual changes such as pigmentation greatly affect the appearance impression, and thus there are many people who want to improve them, and various products are provided.
In order to prevent/improve wrinkles, sagging, and pigmentation, many effective ingredients have been proposed. Among them, niacinamide (niacinamide) is known to be highly safe as an active ingredient for wrinkles and sagging and to have an effect of preventing skin aging. In addition, as a whitening agent for improving or suppressing pigmentation, the use of tranexamic acid has been proposed. However, it is known that if a large amount of nicotinamide or tranexamic acid is contained, there is an undesirable feeling of use such as stickiness.
On the other hand, there is disclosed a technique of suppressing stickiness while having an effect of improving wrinkles by blending nicotinamide, a silicone oil having a viscosity of 25mPa · s or less at 25 ℃, a polyether-modified silicon, and carboxymethyl cellulose (for example, see patent document 1).
Further, there is disclosed a technology of a cosmetic lotion having a wrinkle-improving effect and a feeling of penetration during use by combining two kinds of alkylene oxide derivatives, a 2-methacryloyloxyethyl phosphorylcholine-butyl methacrylate copolymer, and a polyol (for example, see patent document 2).

That is, the component (c 1) is obtained by adding propylene oxide (generally referred to as "propylene oxide" or the like) and ethylene oxide (generally referred to as "ethylene oxide" or the like) to glycerin in a total ratio of 3 to 180 molar equivalents relative to glycerin, or further adding an alkylene oxide having 4 carbon atoms (generally referred to as "alkylene oxide" or the like) in a ratio of 0 to 15 molar equivalents relative to glycerin. The glycerol derivative of the component (c 1) can be obtained by synthesizing an adduct of PO and EO at once and then adding an alkylene oxide having 4 carbon atoms in a block form.
The component (c 1) has a mass ratio (PO/EO) of Propylene Oxide (PO) to Ethylene Oxide (EO) of 1/5 to 5/1, and the addition form of propylene oxide and ethylene oxide may be random or block. When the mass ratio (PO/EO) of Propylene Oxide (PO) to Ethylene Oxide (EO) is less than 1/5, the feeling of penetration, the moisturizing feeling immediately after coating, and the persistence of the moisturizing feeling are reduced, and when it exceeds 5/1, the feeling of non-stickiness or the feeling of penetration is reduced.
