This group of salts is formed by the reaction of an organic base with either an inorganic or organic acid or by the reaction of an inorganic base with an organic acid. Prominent members of this class are the salts of Carboxylic Acids. The use of salts is preferred as a rule over that of acids and bases since salts may be more stable raw materials and because salts exhibit greater water solubility.
In cosmetics, salts are used for their specific chemical effects (e.g., Ammonium Thioglycolate for hair waving; Sodium Lactate as a humectant; Brucine Sulfate as a denaturant for ethyl alcohol; and Sodium Saccharin as a sweetener).
The following listing excludes the salts of amines and alkanolamines which are classified as Amines, and the salts of fatty acids, which are classified as Soaps. Also excluded are the salts of anionic and cationic surfactants, which can be found in the class listings of the functional groups responsible for surface activity. Finally, the salts of polymeric substances are listed under Gums, Hydrophilic Colloids and Derivatives, Biological Polymers and Synthetic Polymers. |
