Abstract
A solid cleaning composition, the composition including: one or more anionic surfactants, wherein the one or more anionic surfactants constitute 40 wt. % to 90 wt. % of the composition; a cationic biocide, wherein the cationic biocide constitute 0.0001 wt. % to 2 wt. % of the composition; and one or more humectants; wherein the one or more humectants constitute 0.03 wt. % to 35 wt. % of the compositions, the cationic biocide retaining its biocidal activity as demonstrated by a reduction of at least 1.0 log 10 in a standard hand wash test.
Claims20
A solid cleaning composition, the composition comprising:
- one or more anionic surfactants, wherein the one or more anionic surfactants comprise 40 wt. % to 90 wt. % of the composition;
- a cationic biocide, wherein the cationic biocide comprises 0.0001 wt. % to 2 wt. % of the composition;
- and
- one or more humectants;
- wherein the one or more humectants comprise 0.03 wt. % to 35 wt. % of the composition, the cationic biocide retaining its biocidal activity as demonstrated by a reduction of at least 1.0 log 10 in a standard hand wash test.
A solid cleaning composition, the composition comprising:
- a quaternary amine biocide;
- one or more humectants, wherein the one or more humectants comprises:
- a polyglycol, wherein the polyglycol comprises 0.1 wt. % to 20 wt. % of the composition;
- and
- one or more anionic surfactants, wherein the one or more anionic surfactants comprise at least 40 wt. % of the composition,
- wherein the composition is a solid at room temperature and pressure and wherein the composition produces at least a 1.0 log reduction in live bacteria as measured by a standard hand wash test.
A solid soap composition comprising:
- a cationic biocide;
- a humectant;
- at least 50 wt. % fatty acid salts;
- and
- at least 5 wt. % syndet, wherein the composition has a pH of 4 to 8, produces at least a 2.0 log 10 reduction of bacteria in ASTM E1174, and produces a moisturizing effect in an Lower Leg Controlled Application Test (LCAT) such that a mean corneometer measurement of a composition treated region drops at least two standard deviations less than the mean drop for a water control.
