A clear soap bar formulation based on sodium cocoyl isethionate (SCI) and method for producing a clear soap bar. The soap bar formulation uses a SCI prepared with metal catalyst (for example zinc) to promote faster and more economical production of SCI. The clear soap bar is formed from a preliminary mixture of propylene glycol, sorbitol, sodium lauryl ether sulfate (SLES), glycerin, water, stearic acid and myristic acid. Sodium hydroxide is added for saponification of the fatty acids to form soap. The resulting mixtures is stirred until homogeneous, and a chelating agent is added. The mixture is stirred again until homogeneous. SCI is then added, and the mixture is stirred until substantially clear. The mixtures is then allowed to sit without stirring for a period of time, in order to allow air bubbles to rise to the top of the vessel. The mixture is poured into molds and allowed to cool undisturbed. The clear soap bar formulation may also contain one or more common soap bar ancillary agents including but not limited to foam stabilizers, humectants, emollients, fragrances, and chelating agents.
