Abstract

PROBLEM TO BE SOLVED: To obtain the subject composition excellent in scrubbing effect and capable of finishing a skin smooth by containing a corn powder. SOLUTION: This skin detergent composition contains a corn powder and is blended with further a polyethylene glycol, a water soluble high polymer, glycerol, water and a surfactant. As the corn powder, a sterilized one by a hot air treatment, etc., is suitable. The blended amounts are 1-3 wt.% corn powder, 10-40 wt.% polyethylene glycol, 0.01-10 wt.% water soluble polymer, 10-40 wt.% glycerol and 1-10 wt.% surfactant. The detergent composition is used by washing with water after massaging the skin therewith. The composition is excellent in scrubbing effect and safety by containing the corn powder which is a natural product and distributed in a large amount, and also the polyethylene glycol improves the smoothness of the skin and helps an easy washing of the composition.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleansing composition, and more particularly to a skin cleansing composition having an excellent scrub effect and smoothing skin.

[0002]

2. Description of the Related Art Conventionally, as a scrubbing agent, sodium chloride, nylon powder, walnut shells, pulverized materials such as apricots and peach seeds have been used in many cases.

[0003]

However, when sodium chloride is used as it is in a scrub, it has problems such as difficulty in massage due to poor sliding and damage to the skin. Gel detergents using surfactants and water-soluble polymers also have drawbacks such as sodium chloride in the product settling out, making it difficult to maintain stability.

[0004] In addition, nylon powder has a risk of causing so-called melasma due to friction with the skin during face washing.

On the other hand, crushed materials such as walnut shells, apricots and peach seeds are natural products, but are very expensive, and because of their structure, are very difficult to remove when they enter the eyes during face washing. It was painful.

In view of the above, as a result, a skin cleansing composition which is a natural product and can be obtained by adding a sterilized corn powder which is distributed in large quantities has an excellent scrubbing effect and is safe. They found that they excelled, and led to the present invention. Accordingly, an object of the present invention is to provide a skin cleansing composition in which corn powder in a product smoothes skin.

[0007]

The above object is achieved by a skin cleansing composition comprising corn powder, polyethylene glycol, a water-soluble polymer compound, glycerin, a surfactant and water. .

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The corn powder used in the present invention is corn maize (Zeamays).
Seed powder. This corn powder is treated with hot air,
Sterilized by conventional methods such as ultraviolet treatment, ethylene oxide gas treatment, and chlorination can be produced without adding a preservative at the time of blending, and are therefore preferably used. The particle size is preferably from 1500 to 150 μm, more preferably from 450 to 1200 μm, and the compounding amount is preferably from 1 to 3% by weight (hereinafter abbreviated as%) based on the total amount.

[0009] The polyethylene glycol used in the present invention improves the smoothness of the skin and makes it easier to clean. The blending amount in the skin cleansing composition is preferably 10 to 40% based on the total amount.

Specific examples of the water-soluble polymer used in the present invention include natural polymers such as guar gum, xanthan gum, carrageenan, quince seed, karaya gum, carboxymethylcellulose and hydroxypropyl starch, carboxyvinyl polymer, polyacrylic acid and the like. The amount of the synthetic polymer in the skin cleansing composition is preferably 0.01 to 10% based on the total amount.

The amount of glycerin used in the present invention in the skin cleansing composition is 10 to 4 based on the total amount.
0% is preferred.

The amount of the surfactant used in the present invention in the skin cleansing composition is from 1 to 10 based on the total amount.
% Is preferred.

The skin cleansing composition of the present invention contains, in addition to the above essential components, a medicinal agent, a moisturizing component, an anti-inflammatory agent, a bactericide, a preservative, and the like, which are used in cosmetics and pharmaceuticals as required. UV absorbers, antioxidants, thickeners, organic and inorganic powders, pigments, fragrances and the like can be added.

The skin cleansing composition of the present invention can be produced by mixing the above-mentioned essential ingredients and the above-mentioned ingredients in a conventional manner. The thus obtained skin cleansing composition of the present invention is used by rinsing with water after massage.

[0015]

Next, the present invention will be described in more detail by way of examples. Example 1 A sterilization process was performed while flowing corn powder in hot air at 120 to 130 ° C to obtain a sterilized corn powder (sample 1). The general viable cell count before the treatment was about 3500 cfu / g after culturing at 30 ° C. for 2 days by the multi-layer coating method.
(Cfu = colony forming unit)
On the other hand, after the treatment, it was 10 cfu / g or less. Example 2 Maize powder was converted to an ethylene oxide gas concentration of 30%.
(Die side H30), 1.2kg / cm2, 60-6
The treatment was performed at 2 ° C. for 10 hours to obtain a sterilized corn powder (sample 2). In this case, the number of general viable bacteria after treatment is 10c
fu / g or less. Example 3 Maize powder was suspended in 1.5 times the volume of water, and 0.1 wt% of sodium hypochlorite (effective chlorine content: about 8%) was added per corn powder, and sterilized for a certain period of time. After that, dehydration and drying were performed to obtain a sterilized corn powder (sample 3). In this case, the number of general viable bacteria after treatment is 10c
fu / g or less.

Example 4 The sterilized corn powder (samples 1 to 3) prepared in Examples 1 to 3 was blended in a usual manner with the skin cleansing composition having the components shown in Table 1. Table 2 shows the results based on the evaluation method.
