Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aqueous peeling used for removing aging keratin, sebum, makeup cosmetic residue, dirt, and the like on the skin. It concerns cosmetics. 2. Description of the Related Art Peeling cosmetics are generally used by first rubbing an appropriate amount on the skin and rubbing them with fingers or the like by applying a physical external force to twist the so-called peeling agent. Aging keratin, dirt, etc. are wrapped and removed. It is known that this removing action smoothes the skin, activates skin respiration and metabolism, and maintains healthy skin. Conventionally, in such peeling cosmetics, organic powders, inorganic powders, water-soluble polymers, and the like have been blended. In particular, when the formulation base is an aqueous base, a blend of cellulose powder as a peeling agent is effective for achieving such a purpose and has been widely used (Japanese Patent Application Laid-Open Nos. 62-238
No. 211). However, the conventional peeling cosmetics, in use, hard to appear twisted, also in order to leave twisted cellulose powder with aging horny and dirt, will be excessive physical force is applied, this is This may cause unnecessary irritation to the skin, forcing a burden, which may lead to troubles such as rough skin. In addition, in the case where cellulose powder is blended in a normal aqueous base, sebum,
It was hardly compatible with oily stains such as makeup cosmetic residues and the removal effect was sometimes insufficient. [0004] In order to improve such a point, attempts have been made to blend oily components such as paraffin wax and candelilla wax together with the cellulose powder, but these compounds have a large physical irritation at the time of rubbing and have a twisted product. In some cases, the fine particles were difficult to coagulate, were difficult to remove after use, and sometimes remained on the skin. [0005] Accordingly, in an aqueous peeling cosmetic composition containing a cellulose powder as a peeling agent, aging keratin, excess sebum, makeup cosmetic residue, dirt, and the like can be effectively removed. It has been desired to provide a peeling cosmetic composition which can be produced and which does not apply unnecessary physical stimulus to the skin and which ensures sufficient safety. Means for Solving the Problems The inventors of the present invention have conducted intensive studies to overcome the above-mentioned drawbacks, and as a result, the present invention has been found to be achieved by mixing a specific amount of a specific compound together with a cellulose powder. And arrived at the present invention. That is, the present invention provides the following components (A) and (B): (A) 1 to 45 % by weight of cellulose powder (B) ethylene glycol monostearate, distear

Fees. Hereinafter, the present invention will be described in detail. As the cellulose powder of the component (A) used in the present invention, a cellulose hydrolyzate conventionally used widely as a cosmetic raw material is suitably used. From a fine particle having an average particle size of about 5 μm to a 50 mesh pass (JIS standard) A fibrous material of about Z-8801 (measured by a net screen) is preferable because it can be easily used as a peeling agent.

The blending amount of the cellulose powder in the aqueous peeling cosmetic composition of the present invention is 1 to 45% by weight (hereinafter simply referred to as%), preferably 1 to 40%. If it is less than 1%, a sufficient peeling effect cannot be obtained, and if it exceeds 45%, a smooth feeling of use as an aqueous dosage form cannot be obtained. The component (B) used in the present invention comprises:
Ethylene glycol monostearate, distearic acid
Ethylene glycol, propylene glycol monostearate
Cole, cholesteryl stearate, monostearic acid
One or two or more sorbitans may be selected and combined as needed. All of these compounds are solid at normal temperature, and have been conventionally blended in cosmetics as oils or surfactants, and include those that function as emulsifying aids and pearling agents. It has been found for the first time that peeling cosmetics are equally effective. The compounding amount of the component (B) is 1 to 40%, preferably 1 to 35%. If it is less than 1% or more than 40%, the effect of the invention cannot be sufficiently obtained. [0009] In the present invention, the cellulose powder and
The total amount of the specific components is 2 to 65%, preferably 5 to 50%. If it is less than 2% or more than 65%, a sufficient effect of the invention cannot be obtained. The form of the aqueous peeling cosmetic composition of the present invention is preferably in the form of an emulsion, cream, liquid or gel, but is not limited thereto. Further, as long as the effects of the present invention are not impaired, oily components and nonionic surfactants, anionic surfactants, ethyl alcohol, polyhydric alcohols, polyethylene glycol, polymer compounds, and the like which do not correspond to the component (B) are used. Perfumes, pH adjusters, cosmetic ingredients, powders, coloring materials, and the like can be blended. The present invention will be described in more detail with reference to the following examples and comparative examples, but the present invention is not limited to these examples. Example 1 A peeling cosmetic composition having the composition shown below was prepared, and the component (B) was examined. Shortness of time until the evaluation is out twisted, lack of irritation to the skin, (high is large enough evaluation point) the size of the twisted distillate, moist feel, for each 1 to 4 points in the name of five items of stickiness Perform a 4-grade evaluation, 5
A total score of 16 or more items was evaluated as ○, a score of 11 or more as Δ, and a score of 10 or less as X. Table 1 shows the results. (Formulation) (% by weight) (B) Component 3.0 Polyoxyethylene monostearate (55EO) 1.5 Liquid paraffin 10.0 Carboxyvinyl polymer 0.2 Triethanolamine 0.2 Ethanol 20.0 Cellulose powder 15.0 Purified water balance [Table 1] As is evident from the results in Table 1, when the component (B) selected in the present invention is blended, the time until twisting is short, the skin is less irritating, and the twisted product is also poor. It was large, could be easily removed after use, had a moist feeling, and was excellent in feeling of use without stickiness. On the other hand, similarly, even if it is in a solid state at normal temperature, wax, waxes,
Such effects could not be obtained when higher alcohols and higher fatty acids were blended. Examples 2-3 and Comparative Example 1 An aqueous peeling cosmetic was prepared according to the formulation shown in Table 2,
The difference in effect due to the change in the amount of the component (B) was examined. As is clear from the results in Table 2, in Examples 1 and 2, good results were obtained for the same evaluation items as in Example 1, but in Comparative Example 1 in which the total amount of the component (B) was too small, No good was obtained. [Table 2] Examples 4 to 5 and Comparative Example 2 Aqueous peeling cosmetics were prepared according to the formulations shown in Table 3, and differences in the effects due to changes in the amount of cellulose powder were examined. As is clear from the results in Table 3, in Examples 4 and 5, good results were obtained for the same evaluation items as in Example 1, but good in Comparative Example 2 in which the amount of cellulose powder was too small. Was not obtained. On the other hand, if the amount of the cellulose powder was too large, the base aqueous component was absorbed, and a product having a smooth feeling in use as an aqueous formulation could not be obtained. [Table 3] The characteristics of the aqueous peeling cosmetics obtained by the present invention are easier to adapt to aging keratin, sebum, makeup cosmetics and stains on the skin than conventional ones, and to the skin when used. It can reduce the physical stimulus to be applied and can be twisted with a gentle force. The component (B), which is an essential component of the present invention, is easily compatible with sebum, skin stains, aging keratin, and makeup cosmetic residues, and has a solid state at room temperature. Since it has the property of being easily twisted, what has conventionally been scraped off with only cellulose powder can be effectively removed by interposing a specific amount of the component (B). Furthermore, since aging keratin and dirt can be efficiently removed, the time from the start of rubbing until the peeling agent is twisted is shortened, so that the burden on the skin is further reduced. In addition, since the twisted products are largely united, the treatment after use is easy and no residue is observed, so that a component more than necessary as an emollient effect is not left, so that a refreshing feeling can be obtained.
