Sodium Hexadecyl Sulfate is used in preparation of black antibacterial PET film.
White paste or liquid with a mild odor. May float or sink in water.
Salts, basic, such as N-HEXADECYLSULFURIC ACID SODIUM SALT, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
Contact with eyes causes mild irritation. May cause skin to dry out and become irritated.
Recrystallise it from absolute EtOH or MeOH and dry it in vacuum [Abu Hamdiyyah & Rahman J Phys Chem 91 1531 1987].
