• RaQbSiO(4-a-b)/2 (1)
• where each R independently represents a monovalent hydrocarbon group having 1 to 30 carbon atoms and no aliphatic unsaturated bond or a silicon atom-containing organic group, each Q independently represents a polyoxyalkylene-containing organic group represented by the general formula:
• —CxH2xO—(C2H4O)t1(C3H6O)t2(C4H8O)t3—Y where x, t1, t2 and t3 are numbers satisfying 2≤x≤8, 0≤t≤60, 0≤t2≤50, 0≤t3≤50, and 2≤(t1+t2+t3)≤110, and Y is selected from among a hydrogen atom, alkyl groups having from 1 to 4 carbon atoms, and a COCH3 group, and a and b are numbers in the ranges 1.0≤a≤2.5 and 0.0001≤b≤1.5;
• (B) at least one monool organic compound selected from (B1) and/or (B2) below and being a liquid at 5° C. and having one secondary alcoholic hydroxyl group but no heteroatom other than oxygen in the molecule:
• (B1) a glycol ether compound having a hydrogen atom substituted by an alkyl group having from 2 to 8 carbon atoms at one end, a secondary alcoholic hydroxy group at the other end, and from 2 to 3 repeating oxyalkylene units having from 2 to 4 carbon atoms,
• (B2) a tripropylene glycol monomethyl ether;
• wherein isopropyl alcohol (IPA) does not exceed 1 mass % of the composition.
