Abstract

PROBLEM TO BE SOLVED: To obtain an emulsified composition, excellent in dispersibility of a hydrophobic powder and further good in emulsion stability and feeling of use by blending the hydrophobic powder with a nonionic surfactant having a specific hydrophile-lipophile balance(HLB) value and a water-soluble polymer in a specified proportion. SOLUTION: This oil-in-water type emulsified cosmetic is obtained by using a nonionic surfactant having <=12 HLB (0.01-10wt.%), a hydrophobic powder (0.1-20wt.%) and a water-soluble polymer (0.01-10wt.%) in combination. Furthermore, an alkyl-modified carboxyvinyl polymer (0.01-10wt.%) is preferably contained in the system. A Pluronic (R) type surfactant (0.01-10wt.%) is further blended therein to afford an emulsified composition, improved in emulsifiability and excellent in emulsification stability. For example, sorbitan monooleate or POE glycerol monostearate is cited as the nonionic surfactant having <=12 HLB. Talc, a polyamide powder, etc., are cited as the hydrophobic powder and gum arabic, dextran, methyl cellulose, etc., are cited as the water-soluble polymer.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an oil-in-water emulsion composition, and more particularly to an emulsion composition having excellent dispersibility of powder, emulsion stability and a good feeling in use.

[0002]

2. Description of the Related Art Conventionally, powders have been incorporated into cosmetic emulsion compositions for the purpose of imparting a dry feel with less stickiness. The emulsified composition is divided into an oil-in-water type and a water-in-oil type according to its emulsification system, and the powder is also divided into a hydrophilic powder and a hydrophobic powder. Generally, when powders are blended in an emulsion composition, hydrophilic powders have been blended in the oil-in-water emulsion composition and hydrophobic powders have been blended in the water-in-oil emulsion composition due to the dispersibility of the powders.

However, in recent years, it has been expected to develop a base material which places more importance on usability, in particular, the free-flowing feeling of use, which is the greatest feature of the powder, and in fact, an oil-in-water type emulsified composition containing a hydrophobic powder, Many preparations in which a hydrophilic powder is mixed with a water-in-oil type emulsion composition have become popular. However, in such a preparation, there is a problem that the dispersibility of the powder in the system is poor, and in some cases, agglomeration or the like occurs immediately after trial production or after aging.

On the other hand, carboxyvinyl polymers, alkyl-modified carboxyvinyl polymers and the like are used from the viewpoints of a refreshing feeling of use and a fresh and moisturizing feeling. In such a polymer emulsion system, the emulsifying power of a usual activator is used. Since it is relatively weak compared to other emulsified systems, the emulsion stability is not always sufficiently satisfactory, such as coalescence of emulsified particles, which is often seen due to factors such as the type of oil and mechanical share such as stirring power. There wasn't.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide an emulsified composition having excellent dispersibility of powder, good emulsion stability and good feeling during use.

[0006]

Means for Solving the Problems As a result of repeated studies to solve the above problems, the present inventor has found that the dispersibility of the powder can be improved by blending a hydrophobic powder and a nonionic surfactant having an HLB of 12 or less. Was dramatically improved and had a good usability. Furthermore, by adding a pluronic type surfactant to this, the emulsifying power is improved, and it is found that an emulsion composition having excellent emulsion stability can be obtained.
The present invention has been completed.

That is, according to the first aspect of the invention, the nonionic surfactant having an HLB of 12 or less is 0.01 to 10% by weight, the hydrophobic powder is 0.1 to 20% by weight, and the water-soluble polymer is 0%. The oil-in-water type emulsion composition is characterized by containing 0.01 to 10% by weight.

Further, in the invention according to claim 2, the alkyl-modified carboxyvinyl polymer is added in an amount of 0.01 in the emulsion composition.
It is characterized by containing 10 to 10% by weight.

The invention according to claim 3 is characterized by containing 0.01 to 10% by weight of a pluronic type surfactant.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The oil-in-water composition of the present invention can be used, for example, in an emulsifier while adding a nonionic surfactant having HLB of 12 or less and a hydrophobic powder to an aqueous phase containing a water-soluble polymer. The content of the water-soluble polymer, the nonionic surfactant and the hydrophobic powder in the composition finally obtained by emulsification is 0.01 to 10, 0.01 to 10 and 0.1 to 20, respectively.
It can be obtained by adjusting the weight percentage.

With this composition, the emulsified composition is

The nonionic surfactant used in the present invention has an HLB value calculated by the formula (1) of 12 or less, and more preferably an HLB value of 10 or less. HLB = 7 + 11.7 · log (MW / MO) (1) Here, MW represents the molecular weight of the hydrophilic group and MO represents the molecular weight of the lipophilic group.
