Description

The present invention relates to oil-in-water cream cosmetics. More specifically, the present invention relates to an oil-in-water cream cosmetic that is hard and creamy but melts when applied to the skin, spreads smoothly, and easily blends into the skin.

Comfort in use is an important factor in cosmetics applied to the skin, such as skin care products. Particularly in the case of cream cosmetics, it is desirable that the product should maintain an appropriate hardness during storage, be soft and crumbly at the start of application, and remain smooth and spread without creaking until the end of application.

One of the factors that influences the feel of cosmetics during use is the method of thickening the cosmetics. Typical thickening methods for oil-in-water emulsified cosmetics include, for example, methods using water-soluble polymers and methods using surfactants.
Water-soluble polymers are used as thickeners for the aqueous phase. Polysaccharides and the like into which alkyl groups and ionic groups (sulfonic acid groups) have been introduced are also used to provide stability when electrolytes are added (Patent Document 1). However, when using any water-soluble polymer, if it is added in an amount sufficient to provide thickening properties and to maintain the stability of cosmetics during long-term storage, it may cause sliminess and spreadability due to concentration during application. The weight and stickiness of the product cannot be avoided.

Furthermore, examples of thickening using a surfactant include a method in which a surfactant necessary for emulsifying the oil phase is used alone or in combination with other components. For example, Patent Document 2 reports a method for preparing a spreadable cosmetic by combining an acylmethyltaurine salt and behenyl alcohol to form an α-gel. However, in order to achieve sufficient hardness with α-gel, relatively large amounts of surfactants and higher alcohols are required, which results in poor feeling of use, such as difficulty in spreading and stickiness when applied to the skin. There were cases where something bad happened.

The cosmetic of the present invention is cream-like with an appropriate hardness when stored, but when applied to the skin with fingers or the like, the viscosity rapidly decreases and it melts, but after that it spreads lightly and smoothly. An object of the present invention is to provide an oil-in-water cream cosmetic that easily blends into the skin and has an unprecedented and excellent feeling of use, which is unique to the present invention.

As a result of extensive studies to solve the above-mentioned problems, the present inventor has developed an oil-in-water cream that has the desired new properties by combining a specific thickener, surfactant, and oil. They discovered that cosmetics can be obtained and completed the present invention.

By having the above-mentioned structure, the oil-in-water cream cosmetic of the present invention has a hard cream-like consistency with a hardness of 10 to 30 N when stored at 25°C, but quickly crumbles to melt when applied to the skin with fingers. After that, you can apply it lightly without getting sticky.
As a result, it is possible to achieve an unprecedented and excellent feeling of use, giving a hard and rich impression while leaving little residue on the skin and blending well into the skin.

The oil-in-water cream cosmetic of the present invention will be described in detail below.

<(A) (meth)acrylic acid/alkyl (meth)acrylate/(meth)acrylic acid POE monoalkyl ether ester copolymer>
(A) (meth)acrylic acid/alkyl (meth)acrylate/(meth)acrylic acid POE monoalkyl ether ester copolymer (hereinafter simply "(A) (sometimes referred to as "ingredients") are

It is 0.3% by mass. If the amount is less than 0.01% by mass, it will not feel like it melts when applied to the skin with fingers, and if it exceeds 1.0% by mass, the appearance of the cosmetic will be rough and the beauty will be impaired. Or, you may not get a smooth feel when applying it.

The oil component is not particularly limited, and various oil components widely used in cosmetics can be blended. However, in the present invention, if the proportion of solid oil is too high, the cosmetic becomes hard and difficult to spread, while if the proportion of liquid oil is too large, the cosmetic becomes soft and tends to melt on the skin.
