Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic containing a whitening agent which gives a sense of quality and palatability. The present invention contains various surfactants and / or ionic polymers and has excellent stability and turbidity. The present invention relates to a clouding agent-containing cosmetic that exerts its effect.

[0002]

2. Description of the Related Art In recent years, cosmetics having a milky white or milky appearance tend to be favored by consumers because of their luxurious appearance.

[0003] As a clouding agent for imparting such a milky white or milky appearance, conventionally, a hardly soluble solid or crystal such as talc, titanium oxide, ethylene glycol distearate or the like has been dispersed, and oils and silicones have been used. Emulsification methods and the like are known, but according to these methods, foaming,
The drawback is that there are many restrictions on the composition, because it is greatly affected by performance such as rinsing properties and finish properties and dispersion stability.

On the other hand, it has been practiced to blend a polymer latex such as vinyl acetate or styrene as a clouding agent into a detergent or cosmetic. For example, JP-A-59-16623
No. 7 discloses a turbidity agent comprising a copolymer emulsion containing styrene and / or methacrylate and an unsaturated carboxylic acid as constituent units and a water-soluble solvent. However, in this case, if a large amount of a surfactant or a polyhydric alcohol is contained, latex particles aggregate during storage, and the long-term stability is insufficient.

In Japanese Patent Application Laid-Open No. Sho 62-63508, the average particle diameter is in the range of 0.005 to 0.2 μm.
Hair cosmetics containing styrene-based latex in an amount of at least% by weight are disclosed. However, the purpose of this is to enhance the style retention by attaching polymer particles to the hair rather than as a clouding agent, and the long-term stability and clouding effect of the clouding agent are not sufficient.

Further, Japanese Patent Application Laid-Open No. Hei 4-230206 discloses a cosmetic using a styrene resin emulsion and an aqueous solution of a carboxyl group-containing acrylic resin neutralized with an alkali as an opaque agent. However, depending on the surfactant or ionic polymer included in this case,
Lack of long-term storage stability.

[0007]

Therefore, the present invention is not affected by the type and concentration of surfactants and additives usually used as cosmetics, and is effective in improving the storage stability at high temperatures and for a long period of time. To provide a clouding agent-containing cosmetic which is excellent in high quality, high quality and taste. "

[0008]

Means for Solving the Problems In order to achieve the above object, the present inventors have conducted intensive studies on a polymer aqueous dispersion which can be stably dispersed in a high-concentration aqueous solution of a surfactant. At times, they have found that the use of a specific polymer protective colloid and a surfactant is extremely effective, and have reached the present invention.
