Description

Oil-in-water emulsified cosmetics for impregnation

The present invention relates to an oil-in-water-type emulsified cosmetic material for impregnation. The oil-in-water-type emulsified cosmetic material for impregnation is impregnated in an impregnated body, and the autocorrelation impregnated body is dipped and applied to the skin with a finger or an application tool.

Previously, as a container for storing liquid cosmetics, a bottle or tube was generally used. However, because bottles and tubes are difficult to carry when going out, and it is difficult to perform makeup easily, in recent years, liquid cosmetics have been developed to impregnate liquid cosmetics in impregnated bodies such as sponges built in small containers, and use fingers and The application tool applies cosmetics in the form of containers to the skin from the impregnated body.

However, in the self-impregnated impregnated body, the oil-in-water emulsified cosmetics that are applied to the skin with fingers or a spreading tool need to consider the filling suitability and retention of the impregnated body, so the feeling of use when applied to the skin And the effect of modifying pores and fine lines is not necessarily sufficient.

Therefore, it is desired to develop an oil-in-water emulsified cosmetic material for impregnation that can maintain the filling suitability and retention of the impregnated body, while exerting an excellent feeling of use and the effect of modifying pores and fine lines.

As shown in Table 1, in Examples 1 to 8, good results were obtained for all evaluation items.

Normally, in order to impart SPF to a primer, fine particles of titanium oxide are blended. For example, if 3% by mass or more of fine-particle titanium oxide is blended, in general, it is easy to feel dry and powdery, and the evaluation of card powder and floating powder after 3 hours tends to be poor, but in the impregnating oil of the present invention In the water-type emulsified cosmetics, it was confirmed that good results can be obtained in all evaluation items even when fine particles of titanium oxide are blended.

For the viscosity of Examples 1 to 8, the viscosity measured at 30°C using a B-type rotary viscometer is about 4000~28000 mPa·s, which can be easily filled and impregnated into any impregnated body, and confirmed in impregnation After that, it can be stably maintained in the impregnated body for a long time. In addition, when it is less than 4000 mPa·s, the feeling of wearing is not sufficient and it is difficult to obtain the effect of pore modification. If it exceeds 28000 mPa·s, it is easy to produce stuck powder over time. The ratio of the non-volatile oil to the total oil is preferably 15-60%, and when it is less than 15% or more than 60%, it is difficult to obtain the effect of the present invention.

The following shows an example of the formulation of the water-in-oil type emulsified cosmetic for impregnation of the present invention. The unit of blending amount is mass %. In addition, in the case of using commercially available raw material products, it indicates the blending amount of the actual components (solid components) excluding solvents and the like.

For formulation examples 1 and 2, blend polydimethylsiloxane and (polydimethylsiloxane/polyglycerol-3) cross-linked polymer to make component (A) cross-linked polyglycerin modified silicon Ketone: For formulation examples 3 and 4, blend (polydimethylsiloxane/(PEG-10/15)) cross-linked polymer to make component (A) cross-linked polyether modified silicone.

Any of the cosmetics shown in the formula examples are excellent in the feeling of use, pore modification effect, and storage stability, and can be applied to various cosmetic products.
