Abstract
A reactive composition comprising between 60% and 98% by weight of sodium bicarbonate, between 1% and 40% by weight of sodium carbonate and between 0.02% and 2.0% by weight of ammonia, expressed in the form of ammonium ions NH4+, and comprising from 0.01 to 5% by weight of a compound selected from the group consisting of hydrocarbons, fatty alcohols, fatty acids, and fatty acid salts.

A reactive composition comprising between 60% and 98% by weight of sodium bicarbonate, between 1% and 12% by weight of sodium carbonate and between 0.02% and 2.0% by weight of ammonia, expressed in the form of ammonium ions NH4+, and comprising from 0.01 to 5% by weight of a compound selected from the group consisting of fatty acids having 12 to 20 carbon atoms per molecule and a salt thereof.
A reactive composition comprising between 60% and 98% by weight of sodium bicarbonate, between 1% and 40% by weight of sodium carbonate, between 0.02% and 2.0% by weight of ammonia and from 0.01 to 5% by weight of a compound selected from the group consisting of fatty acids having 12 to 20 carbon atoms per molecule and a salt thereof, wherein the ammonia expressed in the form of ammonium ions NH4+is defined as being gaseous ammonia (NH3) released from a product sample by heating at 30° C. during two hours and capturing the released gaseous ammonia (NH3) from the heating operation by condensation in a scrubber with HCl solution to transform the ammonia into NH4+, which is analyzed by a colorimeter.
A reactive composition comprising between 60% and 98% by weight of sodium bicarbonate, between 1% and 40% by weight of sodium carbonate and between 0.02% and 2.0% by weight of ammonia, expressed in the form of ammonium ions NH4+, and comprising from 0.01 to 5% by weight of a compound selected from the group consisting of hydrocarbons, fatty alcohols, fatty acids, and fatty acid salts.
