Embodiment Construction

[0018] The present invention provides diluted thickened aqueous (aqueous) liquid cleansing compositions comprising:

[0019] - one or more surfactants;

[0020] - one or more viscosity modifiers.

[0021] More specifically, the present invention provides diluted thickened aqueous liquid cleansing compositions comprising:

[0022] - at least two anionic surfactants both of which are alkyl ether alkali metal sulfates;

[0023] - at least one electrolyte as viscosity regulator;

[0024] Wherein the ratio of the amount of surfactant to the amount of electrolyte is about 4.3 to about 12.

[0025] A preferred ratio is from about 9 to about 11.

[0026] Surfactant

[0027] The compositions of the present invention require at least one surfactant selected from anionic, amphoteric, zwitterionic and nonionic surfactants and combinations thereof. Preferred compositions of the present invention contain at least one anionic surfactant and at least one other surfactant selected from ...

Abstract

The present invention discloses cleaning compositions comprising a combination of surfactants and viscosity modifying agent including electrolyte, that upon dilution thickens so as to form a gel. The compositions are useful for household cleaning activities such as dishwashing. They provide enhanced and progressive retention of surfactant in carriers, thus avoid excessive product consumption and providing more yield.

Description

field of invention [0001] The present invention relates to cleaning compositions, their preparation, cleaning methods and methods for enhancing the retention of cleaning agents on carriers. More precisely, the present invention relates to cleaning compositions for hand dishwashing. Background technique [0002] The ability to provide liquid household cleaning products that thicken upon dilution is known in the art, as detailed in the following references: [0003] US 5,922,664 describes a composition containing a micellar dispersion of a mixture of at least two anionic surfactants having different resistances to electrolytic salting out and alkali metal citrates. The resulting viscosity upon dilution does not exceed 1,400 mPas. [0004] EP 314,232 mentions a composition: (a) a primary surfactant selected from amines, amine oxides, betaines or quaternary ammonium compounds, preferably amine oxides, (b) a hydrotropic co-surfactant , such as ethanol, methanol or triethanolam...
