To improve mountability and productivity by applying a adhesion-proof agent compsn. consisting of specific ratios of either of calcium stearate or magnesium stearate in the form of fine powder or fine grains or a mixture composed thereof and silicone oil, etc., to a condom consisting of natural rubber, etc.

This adhesion-proof agent compsn. for the condom is prepd. by adding and mixing 0.1 to 20 pts.wt. either of the calcium stearate or magnesium stearate or mixture composed thereof to and with 100 pts.wt. silicone oil or ap. oily material. For example, the adhesion-proof agent compsn. is obtd. by adding 0.1 pt.wt. granular calcium stearate having an average grain size of about 30μm and smooth surfaces to 100 pts.wt. dimethyl polysiloxane-based silicone oil having a viscosity of about 50mm2/s. This compsn. is applied approximately uniformly on both surfaces of the condom made of natural rubber latex to obtain the humid condom. The operability, mountability and touch are improved by such constitution.
