Definitions
- the present invention relates to liquid detergent compositions, particularly to dishwashing compositions comprising high levels of nonionic surfactants and suds enhancing polymers.
- Non food derived soils which are often found include, for example lipstick and nicotine.
- the soils which are the hardest to remove are usually greasy soils.
- Particularly difficult soils to remove are those which have been baked-on or burnt-on or soils which have been allowed to harden onto the dish article.
- Nonionic surfactants are widely used in detergent compositions. However, except for selected nonionic surfactants, the art teaches their use generally is limited to lower levels in certain polymer-containing compositions. For example, U.S. Patent 5,167,872, issued December 1 , 1992 to Pancheri et al., states: "However, when the level of anionic surfactant is less than about 20%, the compositions should not contain any substantial amount of conventional nonionic surfactant, e.g., an alkylpolyethoxylate, in addition to the polymeric surfactant. Large amounts of conventional nonionic surfactants, e.g., more than about three or four percent, tend to harm the sudsing ability of the compositions.” (At column 8, lines 25-32.)
- Example XXIII therein provides grease control results for a composition containing a preferred polymer useful in the present invention (designated therein as compound U).
- this composition does not contain any nonionic surfactant, consistent with the hereinbefore noted teachings of this document.
- the present invention has discovered that selected polymers of this type provide enhanced sudsing for these liquid dishwashing compositions, even when higher than 3% nonionic surfactants are present.
