Abstract: The object of the present invention is to provide a flame-retardant resin composition which has a high heat resistance, superior impact resistance and superior flame-retarding properties. The present invention provides a flame-retardant resin composition which is characterized by the fact that said composition contains (A) a polycarbonate type resin, (B) a silicone resin constructed from siloxane units expressed by the formula RSiO1.5 (T units) and siloxane units expressed by the formula R3SiO0.5 (M units), or a silicone resin constructed from T units, M units and siloxane units expressed by the formula SiO2.0 (Q units) (R indicates an unsubstituted or substituted monovalent hydrocarbon group with 1 to 10 carbon atoms), and (C) an anti-drip agent, and the aforementioned composition contains 0.1 to 9 parts by weight of the abovementioned silicone resin (B), and 0.01 to 10 parts by weight of the abovementioned anti-drip agent, per 100 parts by weight of the abovementioned polycarbonate resin (A).

Abstract: To provide a flame-retardant resin molding that has high heat resistance and excellent impact resistance and flame retardancy.

Abstract: A cleaning composition comprising at least one low molecular weight polyorganosiloxane selected from the group consisting of straight chain polydiorganosiloxane represented by a general formula: ##STR1## (wherein R.sup.1 is an organic group of single valence substituted by the same or different group or unsubstituted, and l is an integer from 0 to 5), and cyclic polydiorganosiloxane represented by a general formula: ##STR2## (wherein R.sup.1 is an organic group of single valence substituted by the same or different group or unsubstituted, and m is an integer from 3 to 7). To use it as a water system cleaning agent, polyoxyalkylene group containing polyorganosiloxane, a surfactant, and water are additionally mixed. Accordingly, a cleaning effect free from environmental destruction and contamination, equivalent to flon containing cleaning agents, and satisfactorily stable in terms of dispersion as a water system cleaning agent can be obtained.
