In addition, this stickproof agent compsn. is applied approximately uniformly on both faces of a wetting condom made of natural rubber, collagen or plastics. As the petroleum waxes, such waxes that contain isoparaffin with the carbon numbers in the constitutional molecules of 31-70 and having side chains are used as the main ingredients and those containing n-paraffin and cycloparaffin are pref. used.</p> |
