ABSTRACT OF THE DISCLOSURE: Disclosed is a composition for concealing graze marks on a transparent glass bottle which comprises: (A) 100 parts by weight of polydiorganosiloxane having a viscosity of 10 to 100,000 cSt at 25° C. in which 15 to 60 mole percent of the organo groups bonded to silicon atoms are organo groups selected from the group consisting of phenyl and aralkyl, (B) 1 to 100 parts by weight of film-forming polyorganosiloxane comprising; (1) two or more straight-chain diorganosiloxane portions comprising at least 10 diorganosiloxane units, and (2) one or more cross-linking portions formed by the reaction of an amino group bonded to a silicon atom through at least one carbon atom and zero or at least one nitrogen atom bonded indirectly to the silicon atom, with an epoxy group bonded to another silicon atom through at least one carbon atom and zero or at least one oxygen atom bonded indirectly to said another silicon atom,wherein the amount of Part (2) in Component (B) is 0.1 to 30% by weight, (C) 1 to 30% by weight of a cationic surfactant or a surfactant mixture of the cationic surfactant and a nonionic surfactant based on the total amount of Components (A) and (B), (D) 60-1,000% by weight of water based on the total amount of Components (A) and (B), said composition being effective to form a film having refractive index of 1.47 to 1.54 on the surfaces of glass bottles.
