Solid cleaner with benzalkonium chloride, PEG-8, and Guar
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.
1. A solid cleaning composition, the composition comprising:
A) a cationic biocide consisting of 0.0001 wt. % to 2 wt. % of benzalkonium chloride (BAC);
B) at least 40 wt. % anionic surfactants comprising:
i) a synthetic detergent;
ii) a soap mixture comprising at least two different C12-C20 fatty acid salts, and a C6-C22 monocarboxylic fatty acid;
C) a polysaccharide moisturizing component comprising guar: and
D) 0.5-5% of PEG-8; wherein:
a) the composition does not contain a polyquaternium;
b) the composition is a solid at room temperature and pressure; and
c) the BAC retains its biocidal activity as demonstrated by a reduction of at least 2.0 log 10 in a standard hand wash test.
2. The composition of claim 1 wherein the synthetic detergent is an isethionate.
3. The composition of claim 1 wherein at least one of the C12 to C20 fatty acid salts comprises sodium oleate.
4. The composition of claim 1 , wherein the C6-C22 monocarboxylic fatty acid comprises stearic acid.
5. The composition of claim 1 wherein the C6 to C22 monocarboxylic fatty acid comprises stearic acid and lauric acid.
6. The composition of claim 1 wherein the C12 to C20 fatty acid salt is selected from the group consisting of salts of lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, and mixtures thereof.
