Abstract

A thickened liquid cleaning composition with desirable cleaning properties and mildness to the human skin comprising a paraffin sulfonate, an ethoxylated alkyl ether sulfate, optionally, a zwitterionic, a clay thickener, optionally, an abrasive and an essential oil and water.

Claims

1. A thickened aqueous liquid cleaning composition consisting essentially of approximately, by weight:

(a) 5% to 15% of a water soluble alkali metal or ammonium salt of a C₈ -C₁₆ ethoxylated alkali ether sulfate;

(b) 20% to 40% of a water-soluble alkali metal salt of a C₁₀ -C₂₀ paraffin sulfonate;

(c) 1% to 6% of a water-soluble betaine;

(d) 0 to 10% of a magnesium sulfate;

(e) 0.5% to 10 wt. % of an abrasive;

(f) 0.25% to 2.0% of a Laponite clay thickener having a particle size of <

2% greater than 250 microns;

(g) 0.2% to 8% of a perfume, water insoluble hydrocarbon or essential oil; and

(h) the balance being water, said composition having a pH of about 5.5.

2. A composition according to claim 1, wherein said abrasive is calcite.

3. The composition of claim 1 wherein the concentration of said abrasive is 0.5 wt. % to 10 wt. %.

4. The composition of claim 3 wherein said abrasive is selected from the group consisting of amorphous hydrated silica, calcite and polyethylene powder particles and mixtures thereof.

5. The composition of claim 1 wherein the concentration of said betaine is 1 wt. % to 6 wt %.

6. The composition of claim 1 wherein the concentration of the magnesium sulfate is 1 wt. % to 8 wt. %.

7. The composition of claim 4 wherein the concentration of said perfume, water insoluble hydrocarbon or essential oil is 0.2 wt. % to 8 wt. %.

8. The composition of claim 6 wherein said hydrocarbon is d-limonene.

9. The composition of claim 1 wherein said clay thickener includes a peptizer.
