Oil mist inhibitor, lubricant containing same, and oil mist reduction method

An oil containing an oil mist suppressant, the oil mist suppressant constituted by a silicone fluid composition having the following properties i) and ii):

• i) the property of increasing the maximum lamellar length of a dimethylpolysiloxane oil having a kinematic viscosity of 10.0 mm2/s at 25° C. by at least 5% when 1.0% by mass of the silicone fluid composition is added to the dimethylpolysiloxane oil;
• and
• ii) the property of being homogeneously miscible with a dimethylpolysiloxane oil having a kinematic viscosity of 10.0 mm2 at 25° C.;
• wherein the oil is a fiber treatment oil, spinning oil, or textile treatment oil;
• wherein the silicone fluid composition comprises:
• (A) 1-100 parts by mass of a silicone compound, where the silicone compound (A) comprises:
• (A2) a cross-linkable organopolysiloxane obtained by reacting;
• (a1) a cyclic or straight-chain organohydrogen polysiloxane, and
• (a2) a polydimethylsiloxane comprising an alkenyl group at least on both ends of the molecular chain,
• in the presence of a hydrosilylation catalyst so that the number of moles of alkenyl groups in component (a2) per 1 mole of hydrogen atoms bonded to silicon atoms in component (a1) is in a range of 0.9-1.2;
• and
• (B) 99-0 parts by mass of a nonpolar silicone oil, other than those equivalent to component (A2), and having a kinematic viscosity of 1-1,000 mm2/s at 25° C.;
• and
• wherein if the silicone fluid composition is a mixture of the silicone compound (A) and the nonpolar silicone oil (B), the two are homogeneously mixed.
