Abstract: The disclosure provides a liquid antiadhesive composition for unvulcanized rubber having excellent anti-adhesion properties and an excellent balance between liquid transferability and stability. The liquid antiadhesive composition for unvulcanized rubber of the disclosure includes: components (A) to (D) below; and water, in which a mass ratio (A)/(D) of the following component (A) to the following component (D) is 5 to 500. (A): Water-soluble polymer other than component (D) (B): Metal soap (C): Surfactant (D): One or more kinds of compounds selected from water-soluble polymers in which thixotropic index (2 rpm/20 rpm) of 2 mass % aqueous solution at 20° C. is 4.

Abstract: The disclosure provides an adhesion preventing agent composition for unvulcanized rubber of which the viscosity is not too high and which allows both lubricity and dispersibility to be obtained in addition to excellent adhesion preventing properties. To achieve the above objective, an adhesion preventing agent composition for unvulcanized rubber of the disclosure includes the following components (A) to (C) and water, wherein the component (B) includes the following components (B1) and (B2), and wherein the mass ratio (B1)/(B2) of the following component (B1) and the following component (B2) is in a range of 1 to 20: (A) a water-soluble polymer, (B) a metallic soap, (C) a surfactant, (B1) at least one metallic soap selected from the group consisting of calcium fatty acid and lithium fatty acid, and (B2) at least one metallic soap selected from the group consisting of zinc fatty acid, magnesium fatty acid, and aluminum fatty acid.
