Abstract
A liquid scouring cleanser composition which does not scratch soft metals, yet has sufficient abrasive action to clean effectively using abrasives having a Mohs hardness of greater than 3, comprises from 2-15% by weight of a soap dispersion formed from the sodium, potassium, aluminum, zinc, calcium, magnesium, ammonium, mono lower alkyl amine, di lower alkyl amine, and tri lower alkyl amine fatty acid soaps, from 20-45% by weight of an abrasive having a Mohs hardness of greater than 3, from 1-7% by weight of an anionic and/or nonionic surfactant, from 0.2-10% by weight of a thickener, and water. The pH of the composition is from 7.0-9.5 and the ratio of abrasive to soap is within the range of from 10:1 to 3:1.
Claims1
An aqueous liquid scouring cleanser consisting essentially of:
- 2-10% by weight of a fatty acid soap having the formula MOOCR wherein M is selected from the group consisting of sodium, potassium and (R.sub.1)mHnN+, wherein m and n are selected from 1, 2 or 3 and m+n=4, R.sub.1 is an alkanol group having 1-4 carbon atoms and mixtures thereof, and R is a saturated or unsaturated alkyl group selected from the group of stearyl, aleayl and mixture thereof;
- 25-35% by weight of an abrasive having a Mohs hardness of greater than 3;
- 1-7% by weight of an anionic surfactant, nionic surfactant or mixtures thereof;
- 0.2-10% by weight of a thickener;
- and water;
- the composition having a pH within the range of 7.0-9.5 and a ratio of abrasive to soap of from 10:1 to 4:1.
