Abstract
A composition and a method of preparing a transparent/translucent moisturizing/cosmetic/personal cleansing bar having a final water content of about 13% by weight or less, preferably about 7% to about 11% water, thereby increasing the melting temperature of the bar to prevent melting and reduce deformation during storage and handling, increasing its hardness and durability, and substantially reducing the tendency of the bar to lose weight over time by evaporation of water by exposure to room temperature.
Claims33
A transparent, pour molded solid bar comprising, by weight:
- 15-65% water-soluble polyhydric solvents, including about 5% to about 35% having three or more hydroxyl groups, and about 10% to about 30% having two hydroxyl groups;
- 5-35% insoluble fatty acid soap;
- 5-40% surfactants;
- and
- 4-13% water.
A method of making a transparent, pour molded bar comprising the steps of:
- (a) mixing 15-65% by weight water-soluble polyhydric solvents, including about 5% to about 35% having three or more hydroxyl groups, and about 10% to about 30% having two hydroxyl groups;
- 5-40% by weight surfactants;
- 5-35% by weight insoluble fatty acid soap;
- and
- at least 4% by weight water,
- at a temperature sufficient to form a molten mixture;
- (b) disposing the molten mixture in a shaped mold;
- (c) dehydrating the molten mixture to 13% by weight water or less if the molten mixture contains more than 13% by weight water;
- and
- (d) allowing the molten mixture to cool and solidify to form said bar.
