Abstract:
1. A process for preparing a cleansing composition having pearlescence, which comprises: mixing an aqueous liquid in which an ingredient (A) is suspended with an ingredient (B), which is molten prior to mixing, or an aqueous liquid in which said molten ingredient (B) is contained; and cooling the resultant mixture to cause said ingredient (B) to deposit on a surface of ingredient (A), wherein: said ingredient (A) is at least one ester selected from the group consisting of an ethylene glycol monoalkylate and ethylene glycol dialkylate, which may have a distribution in the number of carbon atoms in its constituent fatty acids, with the proviso that fatty acids having carbon numbers of 18 and greater account for less than 70 wt. % of all of said constituent fatty acids; and said ingredient (B) is at least one ester selected from the group consisting of an ethylene glycol monoalkylate and ethylene glycol dialkylate, which may have a distribution in the number of carbon atoms in its constituent fatty acids, with the proviso that fatty acids having carbon numbers of 18 and greater account for 70 wt. % or more of all of said constituent fatty acids wherein said cleansing composition exhibits a pearlescence stability of at least 1 month at 50° C. at a pH of 3.8.
