JPH10182431A - Water-soluble infiltration agent for rolled part of condom, and condom coated with water-soluble infiltration agent for rolled part of condom - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve a problem that a silicone oil having mainly been used as a lubricant or condoms can easily not be washed out due to the oily property of the silicone oil, when the silicone is adhered to a body or a wear, and another problem that a conventional water-soluble lubricant is insufficient in infiltration into the rolled part of the condom, when applied to the rolled condom, thereby causing troubles such as the mutual adhesion of the rubber film to prevent the unrolling of the condom on use and the whitening of the condom due to the absorption of the water to deteriorate the physical properties of the condom as well as the appearance. SOLUTION: This water-soluble infiltration agent comprises the aqueous solution of one or more kinds of compounds selected from among sodium lactate, trimethylglycine, sodium dl-malate and monosaccharides. The water content of the aqueous solution is 40-80wt.% in the case of the sodium lactate solution, the trimethylglycine solution or the mixture solution of the sodium lactate with the trimethylglycine, and the water content is also 50-70wt.% in the case of the solution of the other compound or the mixture of the other compounds.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-soluble lubricant applied to a condom, and a condom coated with the water-soluble lubricant, and more particularly to a rolled-up condom having excellent penetration into a roll-up portion. The present invention relates to a water-soluble wound part penetrating agent which does not cause whitening of a condom and is easy to wash off.

[0002]

2. Description of the Related Art Conventionally, silicone oil has been mainly used as a lubricant for condoms, and if silicone oil is applied to a condom before being wound up, it becomes difficult to wind up the condom. For this reason, condoms are rolled up into a shape for packing and shipping, and then silicone oil is applied and adhered to the condom. However, since silicone oil is oily, it is not easy to wash it off when it adheres to the body or clothing.

[0003] As a solution, various water-soluble lubricants have been proposed. However, even if the conventional one is applied to a rolled-up condom, the rubber film sticks to each other because it does not easily penetrate into the condom rolled-up part, and cannot be rolled down during use. Problems such as deterioration or deterioration in physical properties often occurred.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and can be easily washed off even if it adheres to the body or clothing. A water-soluble wound-up penetrant for condoms that is excellent and does not whiten the condom due to water absorption.
An object of the present invention is to provide a condom to which the wound portion penetrating agent is applied.

[0005] The above object is achieved by a condom water-soluble wound part penetrating agent and a condom coated with a condom water-soluble wound part penetrating agent described in the claims. That is,

(1) A condom water-soluble wound-portion penetrating agent which uses an aqueous solution which is excellent in penetrating the condom into the wound portion of the condom and does not cause whitening of the condom. (2) Excellent infiltration of condoms into the wound part, and
An aqueous solution that does not whiten the condom is sodium lactate,
The water-soluble wound part infiltration agent for condoms according to (1), which is an aqueous solution in which one or more of trimethylglycine, dl-sodium malate and monosaccharides are dissolved. (3) It has excellent penetration of the condom into the wound part, and
The water content of the aqueous solution that does not whiten the condom is 40 to 8 in the sodium lactate solution and the trimethylglycine solution.
0% by weight, 50-70% by weight for dl-sodium malate solution and monosaccharide solution, 40-80% by weight for a mixed solution of sodium lactate and trimethylglycine, 50-70% by weight for a mixed solution of other two or more kinds Is in the range of
(2) The water-soluble wound part penetrant for condoms according to (2). (4) A condom to which the water-soluble wound part infiltration agent for condoms according to any one of (1) to (3) is applied.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION As a result of repeated experiments based on a number of findings, the present inventor has found that a plurality of water-soluble winding portions having excellent suitability as a condom winding portion penetrant under the following mixing conditions. It was confirmed that an infiltrant was obtained.

[0008] (1) When an aqueous solution of sodium lactate is used alone, when the water content of the aqueous solution is in the range of 40 to 80% by weight, excellent infiltration into the wound portion of the condom is exhibited. If the water content is less than 40% by weight, sufficient penetration cannot be obtained, and if the water content exceeds 80% by weight, whitening of the condom occurs.

(2) When an aqueous solution of trimethylglycine is used alone, when the water content of the aqueous solution is in the range of 40 to 80% by weight, the trimethylglycine exhibits excellent infiltration into the wound part of the condom. When the water content was less than 40% by weight, trimethylglycine did not dissolve in water, and in the region exceeding 80% by weight, condom whitening occurred.

(3) When an aqueous solution of dl-sodium malate is used alone, the water content of the aqueous solution is 50 to 50%.
When the content is within the range of 70% by weight, it exhibits excellent infiltration properties with respect to the condom rolled portion. When the water content is less than 50% by weight, dl-sodium malate does not dissolve in water,
In the region exceeding 70% by weight, whitening of the condom occurred.

(4) When an aqueous solution of xylose, glucose and fructose among monosaccharides is used alone, when the water content of the aqueous solution is in the range of 50 to 70% by weight,
It exhibited excellent penetration into the condom rolled-up portion. When the water content was less than 50% by weight, the monosaccharide did not dissolve in water, and in the region exceeding 70% by weight, the condom was whitened.

(5) When an aqueous solution obtained by mixing two or more aqueous solutions of sodium lactate, trimethylglycine, dl-sodium malate, and monosaccharide is used, a mixed solution of sodium lactate and trimethylglycine is used. When the water content is in the range of 40 to 80% by weight,
It exhibits excellent penetration into the wound part of the condom. If the water content is less than 40% by weight, the condom may not be dissolved in water, and if the water content exceeds 80% by weight, whitening of the condom occurs. In the case of other two or more mixed solutions whose water content is in the range of 50 to 70% by weight,
It exhibits excellent penetration into the wound part of the condom. If its water content is less than 50% by weight, it may not be dissolved in water, and if it exceeds 70% by weight, the condom will be whitened.

[0013]

As described above, according to the present invention, it is possible to eliminate the difficulty of the conventional oil-based lubricant such as silicone oil, which is difficult to wash off when it adheres to the body or clothing, and to easily remove it with water. The condom roll-up portion penetrates the condom roll-up portion that can be washed off and does not cause the problem of infiltration into the condom roll-up portion which the water-soluble lubricant proposed so far has and the condom whitening due to water absorption. And a condom to which the wound portion penetrating agent is applied can be obtained.
