Abstract
A two-stage method produces a liquid soap, having an alkaline pH and stable viscosity, so as to be efficacious in controlling pathogens and generating a thick lather which optimizes its cleansing and disinfecting effects. The method involves saponification of natural and/or synthetic oils/fats using of two lyes—potassium hydroxide and sodium hydroxide—which, when combined in roughly equal proportions, yield a lathery liquid soap without the need for synthetic surfactants or chemical thickeners. The method is also distinctive insofar as it first produces a solid soap concentrate, from which the liquid soap can be made simply by dissolving the solid soap concentrate in water.
Claims4
A method of producing a liquid soap from a solid soap concentrate, comprising the following steps:
- (a) providing a constituent composition of the solid soap concentrate, consisting of (i) a fatty constituent, which consists of one or more fats, oils, fatty acids, or mixtures thereof, (ii) a first lye constituent, which consists of potassium hydroxide, (iii) a second lye constituent, which consists of sodium hydroxide, and (iv) water;
- wherein the constituent composition by weight consists of 60-70% of the fatty constituent, 5-10% of first lye constituent, 5-10% of the second lye constituent, and 20-30% of the water;
- (b) dissolving the first lye constituent and the second lye constituent in the water to produce a lye solution;
- (c) cooling the lye solution to 100°-115° F.;
- (d) heating the fatty constituent to 100°-115° F.;
- (e) saponifying the fatty constituent with the lye solution to produce a neat soap;
- (f) decanting the neat soap to a soap mold and cooling to 110°-115° F.;
- (g) dividing the neat soap to form multiple pieces of the solid soap concentrate and drying the pieces for 1-3 days;
- (h) packaging the solid soap concentrate with consumer directions for a conversion process of the solid soap concentrate into a liquid soap, wherein the conversion process comprises dissolving the pieces of the solid soap concentrate in water;
- and
- (i) producing the liquid soap in accordance with the conversion process.
