Abstract
Concentrated cleaning compositions are described which exhibit an increase in viscosity simply upon dilution with water. The concentrated and diluted ("ready-to-use") versions are useful in removing food and petroleum grease from hard surfaces (particularly non-horizontal surfaces), and may be formulated as petroleum degreasers, hand soaps and bathroom cleaners. The inventive compositions include an aggregate-forming organic compound, for example an amine oxide, and a nonaggregating or mildly aggregating organic compound, such as an organic alkyl alcohol having from about 4 to about 20 carbon atoms.
Claims7
A concentrated cleaning composition which readily increases in viscosity upon dilution with water, the concentrated cleaning composition comprising:
- A) an aggregate-forming organic compound;
- B) a nonaggregating or mildly aggregating organic compound;
- the aggregate-forming compound and the nonaggregating or mildly aggregating organic compound providing a viscosity of less than 1 second BC, the composition being readily dilutable without significant shearing, and adapted to have a viscosity of at least about 5 seconds BC at a weight ratio of water to the composition of 8:1 and greater without the addition of desolubilizers, additional surfactants, hydrophobically modified polymers, or a combination thereof, wherein:
- (i) the aggregate-forming organic compound is quaternary amine salts;
- and
- (ii) the nonaggregating or mildly aggregating organic compound is selected from the group consisting of octanoic acid , nonanoic acid and lauric acid,
- said quaternary amine salt and said nonaggregating organic compound present at a weight ratio of quaternary amine salt to nonaggregating organic compound within the range from about 1:1 to about 5:1.
A concentrated cleaning composition comprising:
- a quaternary amine salt within the general formula (II):
- ##STR5## wherein R.sup.1 and R.sup.2 are the same or different and are selected from the group consisting of alkyl and substituted alkyl groups, R.sup.3 is selected from the group consisting of straight chain alkyls having from about 10 to 20 carbon atoms, branched chain alkyls having from about 10 to 20 carbon atoms, straight chain heteroalkyls having from about 10 to 20 carbon atoms, and branched chain heteroalkyls having from about 10 to 20 carbon atoms, R.sup.4 is selected from the group consisting of alkyl groups having from 1 to about 5 carbon atoms, and X is a halogen atom;
- and
- a non-aggregating or mildly aggregating compound having a water solubility of less than 1% by weight at 20.degree., said quaternary amine salt and said nonaggregating organic compound present at a weight ratio of quaternary amine salt to nonaggregating organic compound within the range from about 1:1 to about 5:1, said non-aggregating or mildly aggregating compound selected from the group consisting of octanoic acid, nonanoic acid, and lauric acid;
- said quaternary amine salt and said non-aggregating or mildly aggregating compound providing a viscosity of less than 1 second BC, the composition being readily dilutable without significant shearing, and adapted to have a viscosity of at least 5 seconds BC at a weight ratio of water to the composition of 8:1 and greater without the addition of desolubizers, additional surfactants, hydrophobically modified polymers, or a combination thereof.
A concentrated cleaning composition which readily increases in viscosity upon dilution with water, the concentrated cleaning composition comprising:
- a) a noncyclic alkanolamide aggregate-forming organic compound, and
- b) a nonaggregating or mildly aggregating mineral oil,
- wherein the noncyclic alkanolamide aggregate-forming organic compound and the nonaggregating or mildly aggregating mineral oil are present in a weight ratio of alkanolamide to nonaggregrating or mildly aggregating organic compound within the range from about 1:1 to about 6:1 to provide a viscosity of less than 1 second BC, the composition being readily dilutable without significant shearing, and adapted to have a viscosity of at least about 5 seconds BC at a weight ratio of water to the composition of 8:1 and greater without the addition of desolubilizers, additional surfactants, hydrophobically modified polymers, or a combination thereof.
