Patent GB-413756-A (GB)
Title: Emulsions
IPC: C09K23/00
Filed: 1933-01-26
Abstract: Aqueous compositions, containing wax-like chlorinated naphthalenes, with or without other waxes, and capable with water of forming emulsions useful for impregnating textiles, paper or leather, as insecticides or fungicides, or in the making of polishing compositions, are prepared by mixing the wax-like substances, liquefied by melting or addition of a solvent, with a limited amount of water in the presence of an emulsifying agent. Colloids such as casein, gelatine, or glue may also be present. Examples: (1) 80 parts of wax-like chlorinated naphthalene of setting point 93 DEG  C. dissolved in 100 parts of trichlorethylene are added with stirring to a warm mixture of 60 parts of water with 10 parts of turkey-red oil, 3 parts of casein and 1 part of strong ammonia; (2) into 50 parts of the chlorinated naphthalene of (1) at 100 DEG  C. 15 parts of potash soap are stirred and 80 parts of water at 80 DEG  C. containing 4 parts of casein and 1 part of strong ammonia slowly added; (3) into 80 parts of the chlorinated naphthalene of (1) at 100 DEG  C. are stirred 20 parts of pale neutral rosin oil, 18 parts of oleic acid, 18 parts of sodium silicate dissolved in 100 parts of water, and 125 parts of water containing 8 parts of casein and 2 parts of strong ammonia; (4) into a mixture of 60 parts of the chlorinated naphthalene of (1), 10 parts of carnauba wax, 20 parts of pale neutral resin oil and 20 parts of oleic acid, at 80--90 DEG  C., are stirred, 2 parts of caustic soda dissolved in 73 parts of water at 80 DEG  C., and 8 parts of casein and 0,5 parts of strong ammonia in 117 parts of water. Specification 414,072 is referred to.ALSO:Aqueous compositions, containing wax-like chlorinated naphthalenes, with or without other waxes, and capable with water of forming emulsions useful as insecticides or fungicides, are prepared by mixing the wax-like substances, liquefied by melting or addition of a solvent, with a limited amount of water in the presence of an emulsifying agent.
