〈潤滑剤の経時変化〉
<Industrial Application Field> The present invention relates to a lubricant used in condoms, and more specifically to a water-soluble lubricant. <Prior Art and Problems> Conventional condoms are mainly made of silicone oil, which is applied or attached to condoms. However, these were smooth and not sticky, and were not satisfactory. In addition, some water-soluble lubricants are applied directly to the genital area, but when applied to condoms, the condoms devitrify due to water absorption and their physical properties deteriorate, so they cannot be applied to condoms. Ta. <Means for Solving the Problems> The present invention was made in view of the above circumstances, and its means are to reduce the amount of water for dissolving polyacrylamide and to obtain a lubricant by mixing glycerin to adjust the viscosity. It was. <Function> By adjusting the viscosity, which has increased due to a reduction in the amount of water in which polyacrylamide is dissolved, with glycerin, devitrification of the condom can be prevented and deterioration of physical properties can be suppressed. <Example> To explain an example of the present invention, a condom is molded by a method well known in the technical field, and is attached to the condom to impart lubricity. Polyacrylamide is added and stirred to dissolve it, and this is mixed and stirred with glycerin in which powdered methylparaben and finely crushed propylparaben, which act as preservatives, are dissolved. Purified water is used to dissolve polyacrylamide, and the water content is preferably 10 to 30% of the total water content. Polyacrylamide is a nonionic polymer flocculant made from acrylamide (monomer), The viscosity of the solution can be changed by changing its concentration, and about 0.2 to 0.5% is added. Glycerin, which is well known in the technical field, is the main component and is 70-90%, with 0.05-0.10% methylparaben and 0.01-0.03% propylparaben added as preservatives. Next, specific embodiments are shown: Purified water 10 Polyacrylamide *1) 0.2 Glycerin 89.7 Methylparaben 0.075 Propylparaben 0.025 *1) Acoflox N manufactured by Mitsui Cyanamid Co., Ltd.
-100 First, add polyacrylamide little by little to purified water and stir for 20 to 30 minutes to dissolve. Then 65
Finely crushed granular propylparaben and powdered methylparaben are added little by little to glycerin soaked in a bath at ~70°C and stirred for about 1 hour. This is added little by little to the purified water in which the polyacrylamide can be dissolved while stirring. Leave to stand overnight as bubbles will appear when stirring.
It was a colorless and transparent solution with a viscosity of 1100CP and a pH of 6.78. <Lubricant changes over time>
