Document Type and Number:

WIPO Patent Application WO/2017/130907

Kind Code:

A1

Abstract:

Provided are an engine coolant composition for automobiles that maintains the thickening effect of a surfactant as a viscosity characteristic-adjusting agent and suppresses the foamability of the surfactant, and an engine concentrated coolant composition for automobiles for obtaining the same. An engine coolant composition for automobiles containing the following components: (A) silicone oil compound; (B) polyether-modified silicone; (C) non-silicone surfactant; and (D) aqueous base, wherein the silicone oil compound (A) contains the following components: (A1) at least one selected from organopolysiloxanes represented by general formula (1) and (A2) filler, the polyether-modified silicone (B) being at least one selected from polyoxyalkylene-modified organopolysiloxanes represented by general formula (2). RmSiO(4－ｍ) ／２（１） R1 2R3SiO－(R1 2SiO)ｘ－(R1R2SiO)y－SiR1 2R3 （２）
