8. A composition according to claim 1-5 (claim 5 inclusive) shall not act as an isotropic mixture on evaporation. The evaporation shall take place normally in a waythat both compounds shall evaporate together when exposed to air and leaving no residue on the material surface.

9. A composition ofthe solvent according to claim 1 and claim 5 shall be made from good grade chemicals and preferably laboratory standard grades. The commercial grade of composition may be used providing thatthetrace of any impurities shall firstly comply with the Consumer Protection Act and/or with the toxicological requirements of United Kingdom and Sweden. Secondly for any trace of impurities shall not exceed morethan 0.05% (=500 ppm).

10. The inventor of this composition has the rightsto dilute the original solvent with water or aqueous potassium orsodium soap orin diluting with ethyl alcohol or propane - 2 - ol, if necessary without altering the ratio ofthe original constituents as 2:98 vAr combined chemicals namely benzyl alcohol and 2-ethoxyethanol.

11. A method of preventing or inhibiting the release of a flammable vapourfrom the solvent characterized by applying the solvent in a well ventilated area. The flash point can be considered as that of 2-ethoxyethanol (flash point 44"C or 111.2 F) approximately. Dilution with water shall resultthe mixtureto be non-flammable.
