DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shaving agent composition used for shaving beards and unnecessary hair with a safety razor, leather or the like (hereinafter referred to as a razor).

[0002]

2. Description of the Related Art When shaving beard and wasted hair with a razor, the shear stress of the beard is reduced and the skin hit by the razor is softened.
It is generally known that in order to improve the adhesion of the razor to the skin, it is effective to bring water into contact with the beard or the skin and make it penetrate. However, when water is simply applied to the beard or skin, the water is not sufficiently adhered to the beard or skin and immediately falls down, resulting in a problem that the beard or skin cannot be sufficiently softened. there were. There was also a problem that the razor was not sufficiently slippery on the skin.

Accordingly, conventionally, solid or powdered soap is foamed while dissolving it in water by hand or using a brush or the like to improve shape retention, and the foam is applied to a beard and skin and then shaved with a razor. Is being done. However, since the foam obtained from the soap has insufficient foam retention, the foam changes into a liquid over time and drips, and there is a problem that the beard and skin cannot be sufficiently softened. In addition, there is a problem that it is necessary to lather at every shaving, which is inconvenient.

In response to these problems, shaving foam aerosol products and "post-foaming" shaving gel aerosol products have been developed as products having improved foam shape retention and convenience of use. This shaving foam aerosol product is obtained by filling a water-resistant shaving foam stock solution containing a soap and another surfactant together with a liquefied gas as a propellant into a pressure-resistant container. A shaving gel aerosol product is a double-structure pressure container in which a foaming agent such as isopentane is solubilized in a mixture of water, a gelling agent such as hydroxyethylcellulose or hydroxypropylmethylcellulose, and a soap (surfactant). And the compressed gas is sealed between the inner bag and the outer cylinder can.

[0005]

However, in the case of conventional shaving foam aerosol products and shaving gel aerosol products, most of the foam formed therefrom is a gas, and the amount of water that comes into contact with the beard and skin is relatively low. There is a problem that it is difficult to sufficiently soften the beard and skin due to the large decrease. For this reason, there has been a problem that the razor has insufficient slipperiness, and the stratum corneum is turned up, and the razor loses, such as congestion and burning. In addition, since soap is used as a surfactant, there is a problem that the skin after washing with water leaves a firm feeling and it is difficult to obtain a moist and smooth feel.

[0006] Shaving foam products are required to be able to shave the same area of the skin a plurality of times.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and can sufficiently soften a beard and skin, improve the slipperiness of a razor, and prevent the razor from losing. It is an object of the present invention to provide a shaving composition capable of giving a good feeling of use after washing and capable of shaving the same area of the skin a plurality of times.

[0008]

In preparing a water-containing, non-foamable, gel-like shaving composition, the present inventors have studied the use of a carboxyvinyl polymer or a copolymer of acrylic acid and an alkyl methacrylate as a gelling agent. It has been found that the above-mentioned object can be achieved by using the coalesced and a high-polymerized polyethylene oxide having a number average molecular weight of 100,000 or more in a specific mixing ratio, and have completed the present invention.

That is, the present invention provides the following component (A):
(B) and (C) (A) Carboxyvinyl polymer or copolymer of acrylic acid and alkyl methacrylate 0.1 to
5.0% by weight (B) Highly polymerized polyethylene oxide having a number average molecular weight of 100,000 or more 0.005 to 2.0% by weight (C) Water balance Offer things.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.

In the shaving agent composition of the present invention, a carboxyvinyl polymer of the component (A) or a copolymer of acrylic acid and alkyl methacrylate is used;
Component (B) and a highly polymerized polyethylene oxide are used. The reason for using these together is as follows.

That is, the carboxyvinyl polymer of the component (A) or the copolymer of acrylic acid and alkyl methacrylate can form a hydrogel having good shape retention. Such a hydrated gel, when applied to the skin or hair, can supply sufficient moisture to them and has less stickiness to the skin, giving a user a favorable feeling of use. However, the hydrated gel composed of the carboxyvinyl polymer of the component (A) or the copolymer of acrylic acid and alkyl methacrylate has insufficient salt resistance, so that a large amount of salt components derived from sweat and the like are present. When applied to non-cleansing skin to which it has adhered, there is a disadvantage that the viscosity sharply decreases and it is difficult to be retained on a beard or skin. In addition, it is said that this hydrated gel is easily removed from the skin by one shaving operation, although it is required to be able to shave the same area a plurality of times during normal shaving. Has disadvantages. Therefore, when a hydrated gel composed of a carboxyvinyl polymer of the component (A) or a copolymer of acrylic acid and an alkyl methacrylate is applied to dry beard and skin, the beard is difficult to shave and The razor loses its slipperiness and loses the razor, such as turning over of the stratum corneum of the skin and congestion.

On the other hand, the high-polymerized polyethylene oxide of the component (B) has good salt resistance and excellent adhesion to the skin, improves the sliding property of the razor, and can be used for a plurality of times in the same area. Withstands shaving operations. However, there is a problem that the shape retention property is not sufficient, and when it is applied to the skin, it drips.

Accordingly, a non-foamable gel-like shaving agent composition comprising a combination of the carboxyvinyl polymer or the copolymer of acrylic acid and alkyl methacrylate of the component (A) and the highly polymerized polyethylene oxide of the component (B). When a product is prepared, it is expected that both disadvantages will appear. Here, non-foaming means that foaming does not occur even when trying to form an aerosol using a propellant, foaming with a mechanical device, or rubbing with hands to foam. Means

However, according to the knowledge of the present inventor, when both are used in a specific mixing ratio, a non-foamable gel-like shaving composition having excellent shape retention is obtained, contrary to expectation. In addition, the composition can sufficiently soften the beard and skin, is excellent in the sliding property of the razor, does not lose the razor, enables a plurality of shaving operations on the same area, and furthermore, hashes. It was found that a good feeling of use can be imparted later. According to this finding, in the present invention, the carboxyvinyl polymer of the component (A) or the copolymer of acrylic acid and alkyl methacrylate and the highly polymerized polyethylene oxide of the component (B) are used in combination at a specific mixing ratio. .

The carboxyvinyl polymer of the component (A) is a water-soluble vinyl polymer having a carboxyl group.

000 number. And a polymer having a structure represented by the following formula: specifically, Pemulen TR-1, Pemulen T
A product specified by a trade name such as R-2 (BFGoodrich) can be used.

Here, the compounding amount of the carboxyvinyl polymer of the component (A) or the copolymer of acrylic acid and alkyl methacrylate in the shaving agent composition is as follows:
It is 0.1 to 5.0% by weight, preferably 0.2 to 1.0% by weight. If the amount is less than 0.1% by weight, the shape retention of the composition is insufficient. If the amount is more than 5.0% by weight, it becomes difficult to spread the composition at the time of application. Clogging is likely to occur, and it is more difficult to wash off.

The non-foamable gel shaving composition of the present invention contains a highly polymerized polyethylene oxide as the component (B). Here, the number average molecular weight of the highly polymerized polyethylene oxide is 100,000 or more, preferably 2,000,000 to 4
One million. If the number average molecular weight is less than 100,000, the sliding properties of the razor will be insufficient. The compounding amount of the highly polymerized polyethylene oxide of the component (B) in the shaving agent composition is 0.005 to 2.0% by weight, and preferably 0.05 to 2.0% by weight.
1 to 0.5% by weight. If the amount is less than 0.005% by weight, the effect of improving the slipperiness of the razor cannot be sufficiently exhibited. If the amount exceeds 2.0% by weight, the razor slides upward and becomes difficult to shave deeply. It becomes easy to clog between the blade razors, and it is also difficult to rinse off. Moreover, stickiness and stringing occur, and the feeling of use is reduced.

The non-foamable gel shaving composition of the present invention contains water in a balanced amount as component (C) in addition to the above components (A) and (B). This water is a component for softening the beard and skin.

The Brookfield viscosity (30 ° C.) of the non-foamable gel-like shaving agent composition of the present invention is preferably 1,000 to 70000 cP, more preferably 1 to 70 cP.
It is 0000-40000 cP. It has a viscosity of 10
If it is less than 00 cP, the adhesion to beards and skin will be too low, and if it is more than 70,000 cP, it will be difficult to apply on beards and skin, and the razor will slide on the skin.
Here, the Brookfield viscosity can be measured using a B-type rotational viscometer (TA-type rotor, 5 rpm / 60 seconds).

Further, the non-foamable gel shaving composition of the present invention preferably contains a polyhydric alcohol as the component (D). Thereby, it is possible to prevent the skin from drying immediately after the shaving agent composition is applied to the skin and shaved with a razor, and it is possible to maintain an appropriate moist state of the skin. Therefore, it is easy to shave the same place on the skin a plurality of times. In addition, the shaving agent composition can improve adaptation to the skin and elongation. Further, a moist and favorable feeling can be imparted to the skin after use.

Examples of such polyhydric alcohols include sorbitol, glycerin, propylene glycol, 1,3
-Butylene glycol, diglycerin, dipropylene glycol, polypropylene glycol, polyethylene oxide having a molecular weight of less than 100,000 and the like.

If the amount of the polyhydric alcohol in the shaving agent composition is too small, the skin cannot be sufficiently moistened, while if it is too large, it becomes difficult to wash off the skin, and the skin becomes sticky after washing off. .0
The content is 1 to 5.0% by weight, more preferably 2.0% by weight or less. When these polyhydric alcohols are blended with the non-foamable gel-like shaving agent composition, one kind may be blended alone, or two or more kinds may be blended in combination.

From Tables 1 and 2, the shaving agent composition of Example 1 uses a carboxyvinyl polymer (0.70% by weight) and a highly polymerized polyethylene oxide (0.30% by weight) in combination. It can be seen that all the evaluation items show excellent results.

On the other hand, the shaving composition of Comparative Example 1 uses the same amount of carboxyvinyl polymer as in Example 1, but does not use highly polymerized polyethylene oxide. Sufficient results were obtained for "slipperiness of the razor" and "losing the razor".

In the case of Comparative Example 2, the same amount of the high-polymerized polyethylene oxide as in Example 1 was used, but the carboxyvinyl polymer was not contained. Received a low rating.

In the case of Comparative Example 3, the carboxyvinyl polymer and the highly polymerized polyethylene oxide were not used,
Since polyethylene oxide having a number average molecular weight of 570 to 630 was used, "slidability of razor", "losing razor", and "shape retention" were insufficient.

The shaving agent composition of Comparative Example 4 uses the same amount of carboxyvinyl polymer as in Example 1, but uses polyethylene oxide having a number average molecular weight of 570 to 630 in place of the highly polymerized polyethylene oxide. Because of the use of the razor, the results were insufficient for "slipperiness of the razor" and "losing the razor".
