Abstract
The invention involves liquid cleaning compositions that are cocamide DEA free. According to the invention, nonionic surfactants can be used as rheology modifiers in combination with various coupling agents to provide an environmentally friendly alternative for traditional liquid cleaning compositions that rely on cocamide DEA thickening agents.
Claims20
A liquid cleaning composition comprising:
- from about 0.01 wt. % to less than 2 wt. % of a nonionic surfactant, wherein said nonionic surfactant comprises a Guerbet alcohol ethoxylate of the formula
- R1—(OC2H4)n—(OH).
- wherein R1 is a branched C9-C20 alkyl group and n is from 2 to 10;
- one or more coupling agents including a protic solvent and an aromatic sulfonate;
- a neutral salt;
- and
- from about 55 wt. % to about 95 wt. % of water;
- said composition having less than 0.5 wt. % of cocamide DEA.
