A liquid detergent composition is provided which contains, based on the total weight of the composition, 5-40 wt. % of an anionic surface active agent, 1-10 wt. % of an amine oxide, 0.5-5 wt. % of an alkali metal halide and 0.04-1.5 wt. % of at least one inorganic salt selected from sulfites, phosphates and thiosulfates. The liquid detergent composition does not corrode a manufacturing apparatus and is excellent in detergency and is mild to the skin.

Amine oxide-and alkali metal chloride-containing non-corrosive liquid

Disclosed is a process for producing the magnesium salt of an olefin sulfonic acid comprising the steps of:

Process for producing magnesium salt of olefin sulfonic acid

Disclosed is a process for producing a clear aqueous solution of the magnesium salt of an olefin sulfonic acid by (i) sulfonating an olefin with an gaseous sulfur trioxide, (ii) neutralizing the resulting sulfonated olefin with an inorganic alkali consisting of magnesium hydroxide and/or oxide and an organic amine selected from water-soluble alkanol amines in specified amounts and, then, (iii) heating the neutralized mixture at a pH of from 6.0 to 8.0. Thus, a clear aqueous solution of the magnesium salt of an olefin sulfonic acid having no bad odor and no color deterioration can be obtained.
